How to increase Your Android Phone's Battery Life tips

Whether it's a lowly T-Mobile G1 or the latest Motorola Droid X, here's how to get the most out of your Android-powered cell phone's battery.
Android-powered cell phones may be powerful devices, but devices like the Motorola Droid X and Samsung Vibrant don't have endless battery life. In fact, many owners would be happy to make it through a single day, hoping that a nightly recharge is sufficient.


Sadly, it sometimes isn't. A number of factors have conspired to reduce gadget endurance over the past several years. Thinner designs with less room for the battery, larger screens, faster processors, software that runs in the background, and power-hungry GPS chips all share responsibility. The move to 3G and 4G networks has also taken its toll. Our battery life test results drop significantly—sometimes more than half—when we're testing an AT&T or T-Mobile phone in 3G mode instead of 2G alone.

But there's much more to poor battery life results than that. Fortunately, there's plenty you can do to stem the flow of juice from your Android device. Try these tips to extend your handset's battery life:
Set display brightness to adjust automatically. Turning down the brightness is obvious. But the automatic adjustment setting is less well known. Activating it means the OS will automatically dim its display in darker environments, including seemingly well-lit indoor rooms.
Reduce e-mail, Twitter, and Facebook polling. This is a big one. Even handset manufacturers like Motorola don't necessary get this. Set your various messaging apps to "manual" and you'll instantly extend your device's battery life by a significant amount.
Kill extra tasks. This one is controversial, because Android does its own task management. Each new version of Android has improved automatic task management. But some programs still misbehave, especially social-networking apps that like to poll the Internet frequently. Having a task killer like Advanced Task Killer around can help neutralize unexpected network access and lengthen your battery life.
Turn hardware features off. It's great that today's phones have GPS, Wi-Fi, and Bluetooth, but do you really need all three activated 24 hours per day? Android keeps location-based apps resident in the background. The constant drain on the battery will become noticeable, fast. If you've got an HTC EVO 4G, you can turn off 4G mode separately—a good thing, since WiMAX consumes extra power but has yet to blanket the country. On AT&T and T-Mobile phones, you can even turn 3G off when you don't need speedy Internet access.
Dump unnecessary home screen widgets. Just because they're sitting on the home screen, seemingly inactive, doesn't mean they're not consuming power. That goes for widgets that poll status updates in the background, as well as ones that just sit there but look pretty and animated.
Reduce RSS feed update frequency. Staying current with the news is fine, but why update feeds constantly in the background? Plenty of third-party apps set their defaults to poll at a set period of time. Others may offer a choice, but give no indication to the user that battery life will suffer as a result.
Android Market can help. Power Manager is a powerful Android app that helps you manage many of the settings we discussed in this article. It also can add a few features here and there when necessary, such as the ability to tune the screen timeout while on a call (although the effect of that one can be miniscule). If your Android device lacks a task manager, try the free Advanced Task Manager.
Check the reviews.  When choosing a phone, make sure that real world talk time is sufficient. You can't go by what the manufacturer says; we've seen variances on the order of several hours of usage in both directions.
