Extreme battery discharge with battery in good condition

So, I just bought a second hand iPhone 6s and the battery discharges very quickly, in one night from 90 to 26. I know it is not a software problem as I have restored multiple times and have all the best settings for the battery (background refresh, etc).

This iPhone had the battery changed in January in an Apple Store as it was eligible for the iPhone 6s battery problem.

With iMazing for mac I see that the battery discharge rate does not goes below 100 mAh (with the average being about 120 - 130 mAh), this is when the screen is off. In comparison my first gen iPad Pro (which is fine) averages a discharge rate of around 15-40 mAh when the screen is off.

Also, the battery is in good condition and it has 287 cycles

Does anyone know what can be causing this?

Answer this question I have this problem too

Is this a good question?

1st- if ur using Macbook check battery Health with coconut battery software.

You can check loadcycles and design capacity... see how many percentage it shows...

Turn off background app refresh.

If design capacity is not good change battery...

If happens again then is mother board issue.

Can u2 ic ou power management ic.
