Android 4.3 Review – Battery Life

I was able to update the Nexus 4 and the Nexus 7 to Android 4.3 pretty early after release because I followed some instructions on the internet that weren’t working for everyone who tried them. Obviously, you can’t let small things like these stop you from updating to the latest and greatest Android version.

Once, Android 4.3 was up and running there was obviously no visible change but very soon I was able to see that most visible customer facing feature of a smartphone, the battery life, had undergone a major, major improvement. With Android 4.2.2, on an average, I was able to get about 10 to 12 hours of battery life in a day. I generally had to top up sometime during the day to last till the night. After I installed Snapdragon Battery Guru, I started to get about 14 hours of battery life.

Once I updated to 4.3, I decided to remove Battery Guru to see how the update was affecting battery life. I am happy to report that with Android 4.3 I get about 18 hours of battery life on an average. In fact if I charge the phone before going to sleep in the night, I can get through the night and the whole of the next day.

More than 24 hours of battery life

More than 24 hours of battery life

Regular use for me is about 30 minutes to 1 hours of voice calls, a lot of mails in and out, some Temple Run or such casual game, a little bit of navigation for about 10 to 15 minutes and a lot of checking for updates on Twitter.

Also, I no longer use Snapdragon BatteryGuru and seriously wonder if I want to or need to. I will give it a try once and see what kind of improvement or (worsening)… whatever the opposite of that is, of battery life occurs and update.

On the other hand, there has been no improvement whatsoever in the battery life of the Nexus 7. I still get about 2 days of usage from it. Maybe that’s why Google switched processors in the Nexus 7 2013. All the improvements in the 4.3 code are really applicable to the Snapdragon processor and the Nvidia chip is just not capable of running things in the new and improved manner.

All in all, since the phone is the main Android device for me, I am happy to have the greater battery life.
