5 Tips to Improve your Android Phone Battery Life
By on October 29th, 2011

Most Android users will generally complain about the poor battery life of their phone. There is a misconception that Android as an OS itself is not battery-friendly. The truth is that all Android phones, except for some HTC phones, have decent battery life. They can easily last you a day, if used properly.

Here are some tips that will help in increasing the battery life of your Android handset-:

1) Turn Off GPS, Bluetooth etc. when not needed – Don’t expect your Android phone to last a day if you always keep the Wi-Fi switched on, or keep the screen brightness at maximum. Always make sure that the unneeded radios of the phone like Bluetooth, Wi-Fi and GPS are switched off when not in use. This will help you conserve a lot of battery.

Users can also try switching to 2G mode when they won’t be using the phone for long stretches to save battery life. They can also turn off Auto-Sync, turn down the screen brightness among other things. Also, restart your phone every once in a while (once a week). This will help in freeing some resources.

2) Use Battery Saving Apps – There are quite a few apps on the Android Market that claim to improve the battery life of your handset. While I have not personally tried all of them, I have used a few of them and they do work. Apps like Juice Defender and Green Power etc. automatically turn off your phone’s data when the screen is switched off and turn it back on when the screen is turned on.

This definitely helps a LOT in increasing the battery life of your handset. In fact, the battery life of my handset improved by almost 40% after installing Juice Defender.

Sadly, there are also downsides to these apps. Since data is turned off when the screen is switched off, apps that run in the background and require data access don’t work properly. Also, your email will be synced every 15 mins (by default). There is also a possibility that these apps might not work effectively on your phone. So if you are not seeing any noticeable gain in the battery life after installing these apps, it’s better to uninstall them.

3) Deep Sleep – Every phone in this world, irrespective of its OS, has a deep sleep mode. When the phone is idle/not in use, the processor and all other components will go into a deep sleep mode, where they sip as less power as possible, and yet prevent the phone from shutting down completely.

In Android, it may be possible that an app running in the background is preventing your phone from entering the Deep sleep mode by causing a wake lock. If your phone is not going to Deep sleep mode, it will hardly last you a few hours, even when its not in use.

Android users can use ‘CPU Spy’ to check whether their phone is going into Deep sleep mode or not. They can use BetterBatteryStats to find out which app is causing a wakelock, and is thus preventing their phone from entering into Deep Sleep mode.
After finding the rogue app, users are recommended to uninstall the app.

4) Root/Install Custom ROM – Another way to get a substanial improvement in the battery life of your phone is to root it, and/or install a custom ROM.

By rooting your handset, users will be able to remove all the pre-installed bloatware on their phone, which will free up some resources and also improve battery life. For a noticeable gain, they can flash a custom ROM or custom kernel, which can improve the battery life of their phone substantially, along with an improvement in the performance of the phone.Flashing a custom ROM will also provide users with more features, and customizability power.

The only downside to rooting/flashing a custom ROM is that the phone’s warranty is void.

5) Mugen – Finally, if none of the above tips are helping you in improving the battery life of your Android handset, its time to invest some money on an extended battery. Software optimization is only one part of the story. If your phone has a huge screen, and comes with a paltry 1200mAh battery, don’t expect it to last a day (Hint: HTC).

This is where the folks from Mugen come in. These people have been making some awesome extended batteries for all the Android phones out there. The best part is that Mugen batteries come in two flavors, one without an extended batter cover (L), and the other one that requires an extended battery cover (XL).

Both the flavors of the Mugen batteries have a significantly higher battery capacity compared to the stock OEM battery. Users can always trade off a thicker phone if they want better (Read: Insanely better) battery life. If they don’t want a thicker phone, they can just buy the normal (L) size battery, which will also improve their phone’s battery life by a few hours.
