Battery test on 2nd hand phone

[SleepingGiant]

Hi, I'm about to buy a 2nd hand samsung s10e and was wondering on how to stress test or know how good the battery health still. 

 

Is there some way to test it like run a benchmark then check the battery drain on the specific phone

 

I really have no idea on what to do while buying a used phone. The outside seems to be all good. My only concern is the battery health

There is the app AccuBattery. If yoi run it and allow it to run in the background,  ot will determine the remaining capacity after a few charging cycles. But you have to research the original battery capacity of the phone and enter it into the original capacity to see how much it has left. My 4-5 yr old Huawei P10 lite has 65% left(1800 mAh out of the original 3000mAh)

So its like meet up, check, looks good, pay, part ways kind of thing.

Yeah. There is not that much else you can check. But to prevent the battery from degrading fast, you can just charge it up to 80%. That way if it were say 20% degraded it would stay at 20% for a much longer time

Well, there isn't really any way to know, at a glance, if the battery is good or not. Just check with apps like AccuBattery and use personal experience with day-to-day use. Over time, you'll get an estimate.

I would have bought a pixel 6, but damn the markup where im from to the msrp is 33.33%

Yeha like others have said, checking battery health takes a couple runs from full to empty and back again.

And since most phones last more then 24 hours nowadays...
