What I did that work:
Delete /data/system/batterystats.bin in adb while in recovery.
Battery history got reset.
But I am looking for an easier way to do this - the android system can reset the battery history on the fly without the need of going to recovery/reboot.
Before you say deleting this file won't help with the battery life - yes, I am very award of this myth. But all that I am looking to do is really just to reset battery history on the fly, because I often amass weeks of battery history that it becomes difficult for me to look at how the battery is doing in the past few days or so.
Charging battery above 90% would of course work, but this is not what I am looking for. I want a way to manually and instantly reset the battery history.
Thank you! I appreciate your input and help.
You tried deleting batterystats.bin which did not immediately take effect. You need to restart phone after deleting it when Android is running.
Immediate reset stats is only available in Android Kitkat 4.4.x.
Open battery history from settings and press that dustbin icon.
3 working solutions for pre-kikat
1) Delete batterystats.bin when android is running and reboot. (You can also do fast reboot from ROM Toolbox or Rebooter app.
Do not confuse with fastboot
Or type this in terminal
# busybox killall system-server
This reboots fast than normal reboot.
2) Delete batterystats.bin from recovery and reboot.
3) Make a script that will delete batterystats.bin and (fast) reboot phone and create its shortcut on home screen.
Press Thanks if helped.
