Google Docs for Android: An early review!!


Since Google's native app for Docs on Android came out last Wednesday, I've been giving it a test drive. Google Docs works well enough in the mobile browser, and many apps have already come out trying to provide sync and edit functions. However, nothing integrates as nicely as a native app direct from the service provider.

When you first start the Google Docs app, you are greeted with a clean, uncluttered home screen with shortcuts to all your items, collections, starred documents, and other helpful things. Text documents, spreadsheets, and PDFs all open quickly and render nicely.

There is also a home screen widget or quick access to starred documents and quick creation of new documents or photos, which Google will run through optical character recognition (OCR) to turn a photo of a document into editable text. And the native app makes sharing a document with your contacts easy.

Now for the hard part: editing documents. The native Google app is great for viewing documents, but for editing, you'll be sent to the browser. The app opens the mobile version of Google Docs first, but you will have the option to switch to the desktop version--which just means you see the site as if you were on a regular PC. With the mobile version, there's no way to close the onscreen keyboard when using a Bluetooth keyboard, even though many other apps seem to be fine with that arrangement. If you close the onscreen keyboard, you lose the cursor, and no text is inserted. The arrow keys also won't move you around the text in the Document, but bounce between page elements instead. This would work for shorter text entry or quick edits, but I didn't last more than a paragraph trying to actually create a new document that way.

So, I moved over to try Google Docs in the mobile browser. The page renders nicely in the browser, but sadly does not function as well as it would on a desktop computer. As with most full versions of Google Apps on a smartphone browser, scrolling does not work quite right. The document renders beautifully, but you can't scroll through it. The arrow keys simply move you around page elements rather than moving the cursor through the text in the document. That means that once your document reaches beyond the bottom of the screen, you can't get to it. Text entry also lagged way behind my typing in the full desktop version.

I turned to Evernote to create a text document mainly because it played nicely with the keyboard, allowing me to close the onscreen keyboard and instead type and navigate my text with the Bluetooth keyboard. I also like the easy syncing of Evernote with my other computers, as well as easy sharing of notes via e-mail.

There are a few alternative Google Docs viewers. MyDocs--in a beta, testing version for now--offers another simple and clean interface for Google Docs, but will still send you to the browser for editing. GDocs has simple editing baked in, but still won't let me minimize the onscreen keyboard when I'm using the Bluetooth keyboard. This app will also allow download of documents for offline viewing or editing.

If you need a more full-featured office suite with stronger document-creation options, check out ThinkFree Office Mobile, Docs To Go, Office Suite Pro, or Quick Office Pro. If you have one of those fancy, bigger-screened, Android 3.0 Honeycomb tablets, you'll want the HD version of Quick Office. For those who prefer open source office software, Open Office Reader can view, but not edit, .odt and .ods files. When not even that is enough, and you simply need access to the whole shebang, LogMeIn Ignition will get you back to your desktop.

The Google Docs app is a clean and simple way to browse and do minor edits to your Google documents, but not quite compelling enough for me to run out and grab an Asus Transformer for writing. Perhaps the most intriguing feature of the Android app--and the one I will definitely be testing more--is the photo document creation with OCR. For quick reference and reading of Google Docs, this is a great addition to my Android smartphone.

Windows Live Messenger is coming to Android Market!!


An official Windows Live Messenger application coming to the Android market on April 11, 2011. Interestingly, unlike its iOS counterpart, this app is developed by Miyowa – the same company that developed the "official" Windows Live Messenger app on the Windows Phone marketplace. 

We’re not sure why they’re choosing to outsource development of a messenger that many people have been waiting for, but we can’t doubt Miyowa’s ability without having actually used one of their apps. It should be noted that several features from its WP7 counterpart are expected to be omitted, such as file transfer. 

This app will be free but ad-supported, and will be compatible with all devices with Android 1.6 or later. The app will feature push notifications and multi-tasking.

While it is good to see Microsoft expanding it’s Windows Live services across multiple mobile platforms, we definitely hope to see Microsoft focusing more effort on their own mobile platform – Windows Phone 7. With MIX 11 coming up next week, perhaps we might hear about official Windows Live Messenger integration in Windows Phone 7 coming as part of their upcoming "Mango" update? Wishful thinking? We hope not.

Planing for a trip to any foreign country??? Here is your translator!!!

If you've ever wandered around a foreign country completely confused by what all of the signs are actually saying, Quest Visual has the answer with its augmented reality Word Lens App for iPhone. Simply point the camera at the text you want translated and the foreign language is replaced instantly on-screen with something you can read.

While translation software has been available before, seeing the converted text in-situ without any pop-ups is both neater and quicker. The speed of translation requires a small amount of text and Word Lens was not designed to read books. Decent light and clear text are also required for the best results, with Quest Visual telling people to "brighten the text with your phone light".

Currently the app is only available for the iPhone on the App Store for free, but you have to pay $4.99 in-app for translation packs. Currently there are only two packs available, Spanish to English and English to Spanish; however Quest Visual has big plans for the software.

"We're starting out with European languages and will expand from there. We won't stop until we get all the way across the globe!" said the official website.

More European languages should be added soon and all will be available to buy in-app, with the rest of the world following after that.

What of other handset users? Quest Visual has big plans on this front too, hinting that apps are on the way for Android, Windows Phone 7, Palm and Blackberry.

"Our goal was to get a great first release on one platform. Keep in touch!" said the website.

Facebook App for Android – Version 1.4 Available

Recently, Android got a new facebook application update (version 1.4). Facebook, being the largest online social networking site, has released a major update for its Android application. The introduction of this new application has helped bring the places and groups together over an optimum utilization of space.

The groups can now share posts within a small group. You need not publish your post with all your friends. It can be done with a small group of friends now. You can even share your place with your group of friends. For example, you can let them know where you are and even have knowledge of where your friends are. Not only that, you can even discover and locate the places nearby.

Additionally, within the application, you can view your recent notifications in your profile. Hence, it creates no disturbance while using your facebook account. The new improved notification system lets you view the comments and posts published on your wall without any havoc. The new update has also fixed up a few bugs for the facebook users.

The new android facebook app update is now available to download and can be downloaded off your android device for free. Simply go to all programs, choose the market icon, click on search, type “facebook”, and simply download and install the application on your Android based phone.

Google Instant For Android 2.2!!

The fact that Google is launching increasingly new services more often and most of them are implemented, at least initially, only in the United States is not a surprise to anyone with the new Google Instant situation is a bit different. Yesterday on the Google Blog announced new optimization search service, already available on desktop or portable systems in the U.S., and portables with the latest version of Android.

Instant Google can be summed up very simply, anything you write on Google generates instant results, there is no need to press the classic search button. But the great advantage is that with each letter you write besides Google suggests search terms in real time, beginning to show results and also in real time.

In your Android phone, for example, simply go to www.google.com then, turn in the bottom of the Google.com the English version. Normally, when you are on this version of the page no longer localized results are given priority, but it can solve this problem. Click on the Locate Me.

Given that the results are displayed in real time consumes more of your Internet traffic at any point you can enable or disable Instant Google, which is currently in testing period (Beta).

In any case the feeling is great, you should not give two or three searches to get the result you are interested in the problem often is that you missed a letter or you must put a word. Everything is resolved in a single website.

BlindType to Power Android!

BlindType was missed by us until now but this is an amazing technology that Google has acquired. Before its acquisition BlindType was expected to be on iPhone and other platforms aswell but now its safe to assume that this patent pending tech will be exclusive to Android.

BlindType predicts what the user wanted to input without any relevance of the keys that were typed. As the name suggests it promoted BLIND typing. This is made possible by mapping the gestures or pattern in which the typing was done (wrt QWERTY layout) and not where the keys are placed.The claims are such that a user might not need to have a keyboard visible at all to type using Blind Type. Just typing on the interface directly would be enough, this sounds crazy! Below is a demo video of BlindType in action. Blind Type goes against the Apple iOS auto correction that is pretty popular and the SWYPE keyboard that we have seen on Android and other platforms. However all of these require user to concentrate on the screen and requires some precision wrt to the pressing of keys. BlindType makes typing completely independent of the keyboard.

OpenFeint Makes Its Way to Android!

Even the most ardent Android fanboy has to admit that the Apple iPhone platform has it licked when it comes to gaming. OpenFeint is trying to change that and the popular mobile gaming company is bringing the heat with a bunch of popular games.

“Android users deserve great games but haven’t had access to enough of them. That changes today,” said Jason Citron, CEO of Aurora Feint. “Hundreds of thousands of people activate Android phones every day, and there is a clear need for high quality games in the marketplace. The major wireless carriers are partnering with us to select the best games from iOS - like Fruit Ninja - to bring to Android.”

A number of top notch games will be getting their OpenFeint Android launch this month, including Mega Jump, Must.Eat.Birds, Solipskier, and MiniSquadron. When all is said and done, Android is expected to see 20 OpenFeint-enabled games in its first month alone. It may be a small number when compared to the 3000 OpenFeint games on iOS devices, but it’s also a great first step that should help introduce Android gamers to the experience without completely overwhelming them.

“This is a big step for OpenFeint and an even bigger step for Android as it becomes a serious mobile gaming platform,” said Jonathan Goldberg, Analyst at Deutsche Bank Equity Research. “OpenFeint ushered in mobile online gaming for iOS devices and we think they’ll lead the revolution on Android.”
In addition to the achievements, leaderboards, and friend-tracking that OpenFeint is known for, Android gamers will also get their own Feint Spotlight app, which will help users to discover new games and even win prizes.

With these games and the upcoming full version of Angry Birds, Android users will be able to hold their heads up high when it comes to gaming.

Alert! Adobe Flash Player 10.1.82.76 Got Loophole in It!

Adobe has disclosed a newly-discovered vulnerability in current versions of the Flash Player and says there are reports that it is being exploited in the wild.

According to Adobe, a critical vulnerability exists in Adobe Flash Player 10.1.92.10 for Android. This vulnerability also affects Adobe Reader 9.3.4 for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh. This vulnerability could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild against Adobe Flash Player on Windows. Adobe is not aware of any attacks exploiting this vulnerability against Adobe Reader or Acrobat to date. 

Adobe is in the process of finalizing a fix for the issue and expect to provide an update for Adobe Flash Player Android operating systems during the week of September 27, 2010. 

While Adobe cautions owners to “follow security best practices by keeping their anti-malware software and definitions up to date”, this advice leaves Android owners in the lurch as there are no best practices or virus definition updates for this mobile OS. There are several security apps available for Android including Norton Mobile Security, droidSecurity, and Lookout, but Google’s mobile OS is a relatively young and untested platform for security applications. We really have no idea how quickly and effectively these applications will respond to a circulating threat.

Android: New Flash Player 10.1.92.10 is Available!

Do your Android phones support Flash Player? If not, Flash 10.1 has been updated to version 10.1.92.10 and is available in the market now. We can not find a changelog available, but you’ve got to figure it’s some simple bug fixes adding to stability.

You will not be asked to update, but you instead have to manually search for the application. After giving the “Install” the previous version should be replaced.

More information to follow, once it is available...

Android Gets Google Voice Widgets!!

Google on Thursday added a standalone Google Voice widget to the home screen on Android phones.

The addition is part of the new Google Voice app, which is available now in the Android Market. It includes two widgets: one for the Google Voice Inbox; and another for Settings.

"Mobile is all about getting super fast access to what you're looking for and Google Voice is no exception," Google wrote in a blog post.

The Google Voice Inbox widget brings voicemails and text messages to the home screen. Flip through messages via the widget, and selected messages will open in the Google Voice app.

The Settings widget, meanwhile, includes four icons that provide access to several features. The phone icon will provide access to the full Google Voice app. The pen and paper icon will let you quickly compose and send free text messages. The smaller phone logo lets you change what calls are placed via Google Voice on the fly. Finally, the red and white stop icon is a "Do Not Disturb" option that will send all Google Voice calls directly to voicemail.

The Settings widget also displays Google Voice credits.

To add the widgets to a home screen panel, press the menu button from the home screen and select "Add>Widgets>Google Voice Inbox or Google Voice Settings." You will need a valid Google Voice account to access them, and they are available free online.

Earlier this week, Google added a "missed calls" notification to Google Voice that will alert users of a missed call via the Google Voice inbox, e-mail inbox, or both. Last month, Google made a form of Google Voice available via its Gmail service, which lets users "chat" within the Gmail interface via free phone calls.

The Latest Android Hacks: Jailbreaking A PS3 With A Nexus One!

If Sony’s PS3 gaming system took a step backward in functionality when Sony disabled its ability to install Linux, it’s just taken two steps forward again.

t4nav, a Senior Member of xda-developers has just discovered a method to hack the PS3 using a Nexus One or a Desire! All you have to do is:


"Download this 
http://www.mediafire.com/?cgst1aw26i26b60
and place it’s contents onto the root of your SD-card.
Then download my flashable boot.img 
http://cl.ly/83b21dd1818a791d857e 
Place that on the root of your card, Reboot into recovery and flash the PS3-signed.zip
Reboot your phone.
Launch terminal emulator…
Then type the following… 
Code: 
#cd sdcard 
#su 
#insmod psfreedom.ko 
Now turn your PS3 off at the wall, and plug in your phone. 
Turn the PS3 back on at the wall. 
Press the PS3 power button followed by the eject key in quick succession…"

"To get back to normal…
Download this… 
http://cl.ly/428e11e2b0c81369761e
Go into recovery… 
Enable USB-storage 
Copy .zip 
Flash .zip"

So far, it’s only been confirmed to work with the Nexus One and Desire, though we’re sure that with proper attention from the dev community, the hack could be ported over to other devices, such as the EVO 4G or Droid X.

Live Wallpaper Creation Tool for Android Phones!

With the use of mobile phones gone much beyond the average call answering and dialing, an extra touch of personalization sure doesn’t hurt!

OwnSkin thinks along similar lines and has released a new Live Wallpaper creation tool for phones running on the Android platform. The application is intended to be pre-school friendly.

When in a mood to customize mobile phones individually, this user generated tool offers a facile solution for wallpapers that are SkinLet filled. The latter is known to be an active component present in the live wallpaper and aids in personalization via animation, phone information and live data from the internet.

The makers believe the wallpapers proffered are among the slickest in the world. Nevertheless, they’re simple to use and cater efficiently to individual requirements. This tool should strike a chord with the digital community and social network enthusiasts alike. After all, innovative and entertaining mobile content doesn’t miff anyone.

Allowing seamless upload of photos for building SkinLet, users can look forward to animation, clock compass and battery details. This interactive wallpaper can also be shared with friends and it doesn’t involve download or installation of any complicated SDK either.

The free application can be downloaded from the Android market and the OwnSkin website.

Android is Gaining in The Mobile OS Market

The Android mobile Operating System is ruling the mobile web market in comparison to Apple's iOS-based devices. The latest mobile-web-browsing numbers from Quantcast show that Android continues to grab mobile share from the iPhone and RIM.

The device which got the third place had a mobile web consumption of 11 percent, while RIM was the last one who managed to exist in the list at the last spot with 10 percent. RIM and other devices have suffered serious losses but the web use on iOS devices has suffered the most due to Android's growth in the mobile web market. 

Now, obviously, when the percentage of one platform goes up, the percentage of another platform must go down. It turns out that Android is the ONLY platform whose mobile consumption percentage did NOT go down.

The August Statistics from the Quancast show that Apple has saved itself for the time being but Mobile web use of iOS devices (excluding iPad) dropped significantly remaining at 56 percent. While RIM and "other" devices dropped down to 9 percent and 10 percent respectively. Android is the only progressive mobile operating service to jump up 2 percent to reach 25 percent, its best achievement since November 2009.

Quancast is expected to reveal the August web consumption details next week. However last month's statistics show that Apple iPhone topped the chart with 36 percent. But the company's iPod line of devices was down to 20 percent. HTC an Android vendor for the first time appeared on the chart with 11 percent of total smartphone web consumption and Motorola was at 10 percent.

In addition to that, it appears a significant number of iPhone users have figured out how to make good decisions. This is great news for Android and Google. They are clearly poised for a win in the mobile industry. I don’t think it will be too long before we see feature-phones disappear entirely and the iPhone lose its rank as king of mobile devices.

Fennec 2.0 Is Coming For Android Users From Mozilla!

Mozilla today released an alpha version of its mobile browser for smartphones running Google's Android operating system.

Fennec 2.0., which is considered to be the power of Firefox 4, has included integrated synchronization. Moreover, it is responsible for boosting performance by rendering processes as well as user interface.

Apart from that there is Electrolysis, due to which the browser interface is able to run in a separate process. With the help of this process Fennic can react faster to user input. The Electrolysis technology also is able to operate with add-ons.

This release includes Electrolysis, which allows the browser interface to run in a separate process from the one rendering Web content," said Parmenter in a post to the Mozilla blog today. "By doing this, Fennec is able to react much faster to user input while pages are loading or CPU intensive JavaScript is running.

Mozilla added its Firefox Sync service into Fennec 2.0., with the help of the service one can keep passwords, browser history, bookmarks, open tabs as well as other data.

Users of earlier editions could take advantage of Sync by means of add-on. In fact, it was the first time when it was decided to add Fennec.

It is possible to install Fennec 2.0 on many smartphones that are based on Google’s Android operating system.

Although Mozilla did not disclose a final release date for fennec 2.0, still it was noted that September 7 is a final deadline for Beta.

We've not had a proper chance to see how stable Firefox is on a mobile phone, but early indications show a surprisingly usable little web browser, though as yet little advantage over the one built in.

Froyo: Adobe Flash 10.1 Available in Android Market

Flash 10.1 is available in Android Market now!. If you're running a device with Android 2.2 Froyo and don't have Adobe Flash 10.1 Mobile yet, you can head to Android Market to download the latest Flash, which will give you access to most of the videos, games, and interactive Flash-based content on the Internet. 

Depending on your device and your operator, you may have already received Flash as part of the firmware OTA upgrade, like the EVO 4G, which was the first device in the U.S. to get updated to Android 2.2. 

In the case with Verizon Wireless with the original Droid, the OS update is now being pushed out for that device to get to Android 2.2, but the OTA firmware upgrade does not come with the Flash package built-in. Rather, the carrier is advising users to head over to Android Market to get Flash installed. 

If for whatever reason you don't want to install Flash from Android Market and you are running a supported device, then you can head over to Droid-Life to get the update.

Android app licensing cracked in less than a month!!

There has been some concern about smartphone apps in recent weeks after a malware app worked its way into the Android store that sent premium-rate text messages to make money for criminals.  What’s more the BBC demonstrated a proof-of-concept Java app that seemed to be a simple game of noughts and crosses, but was copying contacts and emails in the background.

A spokesperson for Google told the BBC about the malware app…

“Google has a system in place that can revoke malicious applications and stop them running on handsets.  Our application permissions model protects against this type of threat.  When installing an application, users see a screen that explains clearly what information and system resources the application has permission to access, such as a user’s phone number or sending an SMS.  Users must explicitly approve this access in order to continue with the installation, and they may uninstall applications at any time.  The spokesperson said the firm advises users to “only install apps they trust”.

In response to developers’ complaints of unauthorized usage of their wares, Google has set up a licensing service, by which – via a set of libraries – an application can hit Google’s server, which stores sales records. Every time an app with this protection is launched, it checks with Google to be sure the copy is legit.

The new system was to replace the old copy protection method within few months, and were considered to be more secure and less problematic. 


Now, NeoWin is reporting that the new licensing scheme for Android apps has been cracked less than a month after coming on-line!!!


The “Licensing Service for Android applications” was supposed to provide developers a “secure mechanism to manage access to all Android Market paid applications.”  In theory, the new licensing system would verify against the Android Market licensing server, which would in turn verify the application against existing sales records. If no sales records were found, the application would show an error explaining that it was not properly licensed.

The man responsible for cracking the security has published a paper on his website in which he details how to reprogram a Java app, which is the language most Android apps are written in, to change its status from unlicensed to licensed.

He says…

I am very much against piracy, and very much pro-Google. I have spent more time researching copy protection for my applications than development of the applications themselves.  Our findings show that most (any?) apps can be easily patched and stripped of licensing protection, making them an easy target for off-Market, pirated distribution. By corollary, this means that sites dedicated to pirating apps can continue to do so, using a few automated scripts mixed with some smarts.

He also provides a video demonstrating his findings.  Google have not yet commented on the crack.

Dive into the sea on your Android with Google Maps!!!

Google Earth 1.1 for Android offers a few new features, but most notably the addition of the oceans. With the new software tools and underwater exploratory landscapes, Android users can tap their inner Jacques Cousteau. Sort of.

Google Earth 1.1 doesn't let you snorkel past schools of fish or snuggle up to reefs teeming with sea life. Instead, it offers Android users the opportunity to see what the Earth's surface looks like beneath the water. Google suggests, for example, that users look at the Monteray Bay Canyon, which it says is larger than the Grand Canyon.

There is a "look around" button that lets users change the angle of view and take a new look at what's under the water.
Another tool added to Google Earth 1.1 is what Google calls the "Explore the Ocean" layer. This layer offers up a collection of photos and videos from contributors from all around the world.

Google Earth 1.1 will work just fine on devices with Android 2.1 and higher. Google reserved some special features for devices running Android 2.2 and up, however.

Google explains, "Google Earth now supports Flash in balloons, so if you have the Flash player installed on your mobile device, you can watch videos right in the balloon."

The new software also has some revised navigational tools. The big addition is support for two-finger scrolling, which allows for easier panning back and forth, up and down to change your view of the ocean's floor. User's can also twist two fingers on the screen to change what they are looking at.


The software works well, but few lags or slowdowns when the software needed to access the network to pull down new mapping information.

Google Earth 1.1 for Android is free download from the Android Market.

Android App Licensing Mechanism Still Easy to Break!!

According to Android Police, Google's new app licensing mechanism designed to protect developers against app piracy is still relatively easy to break. The site says that since the License Verification Library isn't a core component of the Android operating system, "an app developer needs to package it with the app that uses it, making it an easier patch target, without requiring root access." As such, running a few simple scripts may break the licensing code. The conclusion is such that "Google’s Licensing Service is still, in my opinion, the best option for copy protection; however, we really need to see a better solution, such as checking the apk for alterations or ways to confirm an application was installed through official means."

News of how easy it is to crack and break license codes for Android Market titles may dissuade some developers from seriously looking at Android. This in turn may hurt consumers if the development community doesn't grow due to concerns about piracy.

Android Phone Can Be Used as a Supercomputer!!

When you hear 'supercomputer' and 'small' in the same sentence, you likely wonder how small a room are they talking about. However, when the folks at MIT and Texas Advanced Computing Center say small, they mean small as in pocket-sized.

A collaboration between MIT and the Texas Advanced Computing Center has led to an Android application that the two institutions claim can do honest-to-goodness supercomputing.

TACC explains that the team at MIT performed a series of expensive high-fidelity simulations on TACC's Ranger supercomputer and then generated a smaller, reduced model, which was used to create an Android application for a Nexus One.

"You don’t need to have a high-powered computer on hand," insists David Knezevic, a post-doctoral associate in mechanical engineering at MIT. "Once you've created the reduced model, you can do all the computations on a phone."

Though this kind of model reduction has been done before, TACC says the MIT system's real advantage is its rigorous error bounds, which tell the user the range of possible solutions, and provide a metric of whether an answer is accurate or not.

Knezevic goes on to say that using a reduced scale model also results in faster computations.

"The payoff for model reduction is larger when you can go from an expensive supercomputer solution to a calculation that takes a couple of seconds on a smart phone," he said. "That’s a speed up of orders of magnitude."

Get Your Android’s Battery Last a Little Longer

A common complaint among Android users is short battery life. As we all now, Google’s platform has numerous benefits, but state-of-the-art features and constantly being connected seem to come with one drawback: comparatively large battery consumption.

I don’t suggest that you should stop taking advantage of the things that make Android great, such as streaming music players that allow you to walk around with millions of songs in your pocket, location-aware apps, background updates or all the wireless options. Still, if you’re frustrated by how often you need to connect your charger, it’s good to know what types of apps and activities that eat the most battery, so you can make an active decision whether or not it’s worth the extra juice.


Use the GPS Wisely

The GPS uses the battery like there’s no tomorrow. Location-aware software is one of Android’s many fortes, but they can be real battery drainers. The Power control widget is useful for switching the GPS on and off, and you should keep an eye on your notification bar: an icon will appear whenever the GPS is activated.


Turn off Bluetooth When You’re Not Using It

Perhaps an obvious tip, but it’s best to disable Bluetooth whenever you’re not actually using it. The quickest way to switch Bluetooth off and on is via a widget on your homescreen.


Disable Wireless Network Positioning

When your device learns your location via wireless network triangulation, it requires less battery than if it had used the GPS. But using both methods simultaneously will of course use the most power. The GPS can handle location tasks by itself, albeit a bit slower. Also, wireless network positioning is used to gather anonymous Google location data in the background, which will drain the battery further. You can turn it off from Settings > Location > Use wireless networks.

Switch off Wi-Fi, or Keep it Always On

If you’re close to a reliable WLAN during the better part of the day, having Wi-Fi always turned on may be favorable from a battery point of view, since the Wi-Fi radio uses less battery than the 3G radio. And when Wi-Fi is on, 3G is off. You can confirm Wi-Fi always stays on by going to Settings > Wireless networks > Wi-Fi Settings. Press the Menu button, tap on Advanced, Wi-Fi sleep policy and select the Never option.

On the other hand, if you’re not close to a strong Wi-Fi signal for extended periods of time, disable Wi-Fi from a homescreen widget or from Settings > Wireless networks > Wi-Fi.



Disable Always-On Mobile Data

The Always-On Mobile Data option is on by default, and can be disabled from Settings > Wireless & networks > Mobile networks > Enable always-on mobile data. It allows your phone to be connected non-stop, but does it need to be? I have disabled the setting, and I still get push Gmail and even Google Talk seems to perform as usual, as well as the few apps I have that use automatic updates. However, if you have a lot of apps that regularly connect to the Internet, disabling this option may actually be a bad idea, since turning the data connection on and off will require more energy than simply having it on all the time.

Kill 3G if Your Phone Often Struggles to Find It

When your Android attempts to decide which signal to lock on to, it strains your battery. If your phone often switches between GSM and 3G in your area, it can be preferable to simply disable 3G altogether, and hence abolishing the need for your phone to try and find a suitable network. Go to Settings > Wireless & networks > Mobile networks > Network mode > GSM only.

Use a Quick Screen Timeout

After a certain time of inactivity, your screen is automatically turned off, and that’s the Screen Timeout. To use such a low value as 15 seconds can be annoying, but one minute is on the other hand likely too long. I use 30 seconds. You can alter this option from Settings > Screen & display > Screen timeout.

Turn Down the Screen Brightness

Android’s Automatic brightness (Settings > Screen & display > Brightness) setting is recommended. If your phone doesn’t have this option, set a reasonable value at roughly 30 % and see if that suits you.

Live Wallpapers Will Use More Power than a Static Background

Oh yes, live wallpapers can be awesome. But they will obviously use precious battery juice, albeit evidently not as much as one could think, talking the eye-candy into consideration and what they can do.

Have an AMOLED Display? A Dark Wallpaper Will Spare the Battery

When having dark backgrounds, phones with AMOLED display will use less power, because each pixel on OLED screens is photoemissive and will actually generate its own light. Since there’s no need for a backlight, the pixel can essentially turn off its light source and go total black. As a result, you can save a teeny-weeny bit of energy by having a dark or black background on AMOLED screens.

Use Widgets Wisely

 Most widgets will only have a negligible effect on your battery life, but those that automatically pull info from the interwebs can be power hogs.

Use Reasonable Intervals for Automatic Updates

I personally don’t need to have automatic updates on my phone, except for emails that I want to be notified of the moment they arrive. I prefer launching the apps at my convenience and see what’s new. Most applications that connect to the Internet have an option to update upon launch, and that’s all I need. By lowering the update intervals, or by even turning them off completely, you can definitely make your battery last longer. I recommend that you reduce them to your own minimum values.

If you have an Android phone with HTC Sense, you can make sure the HTC Mail Client, the HTC Weather App, Facebook, Flickr, Stocks and Twitter update themselves as often as you want them to. This is mainly done from Settings > Accounts & sync. It’s also a good idea to look over third-party apps that grab data from the Internet, particularly the official Facebook app and the various Twitter apps, since they usually have background updates on by default.

Streaming Apps Will Use a Lot of Battery

I certainly don’t think you should avoid streaming application on your phone. But bear in mind that software that stream audio and similar apps will use plenty of power.

Learn What’s Been Drinking the Juice

Unless you have the doubtful pleasure of still running Cupcake, you can check out a built-in Android feature that tells you precisely how much your apps use the battery. You can then start using battery drainers less often, or simply uninstall them. Go to Settings > About phone > Battery > Battery use and press the items in the list for further info. You can also use JuicePlotter to analyze usage patterns.

I have gotten good results by making the tweaks and changes above, and I hope you will too. Do you know of any more tricks that can make our dear Android stay on his feet a bit longer before it needs to be charged? In case you don’t want to keep all this in mind, an app such as JuiceDefender is a good option.
