how to test battery

[ezzzzz]

i bought a used 6p and i only get abt 2.5 hours SOT. my wife consistently gets 3.5-4. how can i check if the battery is physically bad. all the stats look good. no power hungry apps.

There are lithium battery testers - but you don't want to spend a few hundred dollars to test a $10 battery. It's a LOT cheaper to just replace it.

You can't really physically test it - all you can do is check how it behaves. I'd suggest charging it fully, then putting it in Safe mode while you sleep. For 8 hours or so just sitting idle it should only lose a few percent.

You could try an app like AccuBattery https://forums.androidcentral.com/e...s?id=com.digibites.accubattery&token=uby0XpFi which supposedly has the ability to estimate the battery health.

YMMV.
