battery percentage mi8

[yago78]

hi,
i replaced the battery of my mi8 but the time on is really low, worse than the old battery. i thought it was the fault of the fake chinese battery and i bought another one. same situation. i restored the rom, deleted the batterystats file, recharged in every way.
if I start it in recovery I can make it work for a long time even if the battery percentage is zero and then it disappears completely...
I recharge power bank, start multiple backups on external devices. all things that draw a lot of charge..so the full capacity of the battery is not read when powered on. what can i do to fix it?
thank you
