I've made a really really simple app that does one simple job. It calibrates your battery. What does that mean?

If you flashed a new ROM, for example, your batterystats.bin folder still contains the old values from the previous ROM.
This can cause high battery drain, because battery is just "not sure" how many percent has your battery.

Battery calibrator formats this batterystats.bin file and deletes the values. From time to time, your device will automatically generate new values
based on the current ROM and current usage (therefore you can calibrate your phone not only when you flash a new ROM).

After a few days of using, you can notice the battery drain is less and less agressive and the battery life is much better than it was after flashing.

Give it a try!

Is this what happens when you wipe Battery Stats through a custom recovery? I remember a post from a Google engineer who said wiping battery stats has no effect.

Not slating your app my friend, I might be totally wrong.

Edit: this is the article I was referring to: http://www.xda-developers.com/androi...-battery-life/

There's a bit of truth. It really dos not improve your battery life. On the other site, it technically improves. For some people (I believe for vast people, including me), the battery indicator is all messed up after flashing and it may show incorrect value. Also, there have been some cases when a device suddenly turns itself off even if there's (let's say) 40% battery.

This happened in my case. I have flashed my Nexus 7. Everything went perfeclty, especially battery life. It was literally "stuck" on 100% for all day. Suddenly it crashed. The battery just (suddenly) drained to 0%. Formatting the batterystats.bin helped and I no longer suffered from this weird bug.


Thanks for feedback

I've seen that occur on my Nexus 7 as well and my Galaxy Nexus can go from fully charged to 0 within an hour lol
