[Q] Resetting battery stats topic

Hi

I have flashed my phone a couple of times and have some how messed up my battery stats.

I'm running CM12 Official nightly and the 5.0 alpha modem.

When i reach about 13 % the phone just turns off to black screen, so no graceful shutdown from low battery.

When i connect the charger, the low battery warning comes up and the after i few seconds it goes to the small battery with percent in it. It says 15% right when it comes up.

When in the small green battery with percent state, is the ROM responsible for showing that screen or is it the modem/bootloader?

How do i reset the battery stats, so that it shows the correct percentage left?

I found this app: https://play.google.com/store/apps/d...ibration&hl=en
Will that fix my problem?

Thanks
