How to Increase Battery Life for Android Phones

I recently upgraded my phone to an HTC One X android phone. The phone performs very well. I have used some Android devices before, including the highly rated Asus Transformer. I was not impressed at all by those Android devices’ performances. This phone actually changed my view of Android. It has a large bright screen with high resolution. Every operation is responsive and does not lag at all. It’s way faster than my iPhone 4. There is, however, only one thing I do not like about this phone: the battery life is way too short. By default, it cannot last for even a day!

I have spent some time learning how to better manage the battery usage. Most of the suggestions I found can help to increase the battery life only by a little bit. Of all the tweaks I found, there are only some that would significantly increase the battery life. Here are the tweaks that I want to share.

Configure Accounts & Sync

On my HTC One X, this is under Settings -> Accounts & Sync. If you turn auto sync completely off, you will notice a dramatic increase of the battery life. However, turning everything off defeats the purpose of having a Smartphone. Instead of turning auto sync off, I just turned off syncing for some apps. For example, I never used the Stocks app: there was no reason for it to sync with the server. Go through all the apps listed under Accounts & Sync and turn off the apps that you do not use. After configuring this, I can now use my phone for two days without charging.

Turn off Fast boot

I usually turn my phone off when I go to bed. The phone  is supposed to keep the charge when it’s turned off, but I found that it still consumes quite a bit of power when I turn it off at night. I estimate it loses about 15% to 20% of battery life. This had me worried a bit. I thought my phone might be defective. I then found out the reason why the battery still drains when it’s off. That’s because I have this feature called fast boot. This is turned on by default. With this feature, the machine is not completely turned off. The phone is put into sleep mode, which still consumes power. I turned fast boot off and the phone no longer drains battery when it’s off. This setting is under Settings -> Power.

Always Exit out of an App

If you do not exit out of an app when you are done, the app is still running in the background. Some apps can drain out power quickly. I learned this when I found out the Weather Channel app used over 60% of my battery because I did not close it. Be sure to check the battery usage from time to time to make sure nothing is out of the ordinary. You can check this info by going Settings -> Power -> Usage.

These are the 3 tweaks which I found affect the battery life greatly. There are, of course, some minor tweaks. I am listing these here:

  • Turn off wifi, mobile data, GPS or Bluetooth when they are not in use.
  • Lower the brightness of the screen.
  • Lower the screen time out.
  • Do not use live wallpaper.
  • Install battery saving apps.
  • Limit use of widgets.
