i know those that are rooted with twrp or cwm installed as a recovery can wipe battery stats, and it reflects on the OS.

however that is the only method i know of to reset the battery stats, a factory data reset may also do this. if that is the route you want to go.

You mean on the usage charts under battery? Every time you recharge and unplug your phone they reset. If you just bump the charge briefly they don't reset. I think you need to fully charge it. After that everything will report usage 'on battery' since unplugging.

You mean fully discharge, right?

No, he means charged. Once you reach full charge battery stats are wiped.

No. Fully charged. Once charged and unplugged everything resets. People remember seeing wipe battery stats in clockwork recovery and think that did something. According to Google they don't.

wiping the battery stats does nothing for battery life, most of us know that, however it does remove the file that reads battery information and you will get a fresh file when the phone boots up and reads the battery level.

Yes, but so does charging the phone. And then then you get a clean run from 100% (or as the case may be - actually 92%). Its much easier to do nothing but charge the phone and let it do its thing than to boot to recovery, wipe stats and reboot. They both clear the battery stats file.

Isn't the batterystats.bin a system file? Would you not need root to clear and reset that file? I was under the impression that over time (regardless of charging and then unplugging) the battery statistics you get are based on overall stats.

Nope. According to Google the battery stats are reset EVERY time the device is fully charged. There is no overall "battery statistics" that stores a lifetime of usage.
