Hi
You can download 3C battery monitor from play store and monitor battery voltage from 36%. If battery voltage drop suddenly then you have battery failure if not this will mean incorrect calculation in system which could be caused by options/features which are not fully monitored by system as Hotspot, battery bank, etc. Or simply phone is on for very long time with very low current drain and then if you start using phone harder high current drain can't be seen by system as average of current drain is still small.
Interesting.
By my opinion this is not battery fault.
Could you please provide screenshot from settings - battery
Main picture and screen on and calls, Wi-Fi on

I want see how long phone is in use, how long screen is on, how long you make phone conversation, ...
I will post screenshots to you when the battery close to be empty but there no difference, this behaviour always happened in light or normal or heavy use.

I tested the battery life with "Battery waster"
From 100% to 50% it takes always 4min for 1% drop. From 50 to 30% it takes 3 min for 1% drop and from 30% to 1% it takes only 1min for 1% drop. I will test the attery with 3C tomorrow.

Hi,
I made a screenshits that you want plus a screenshots to 3c battery.
The strange thing is although i didn't use the wifi in this period and is switched off all the time, the system saw it is on and didn't consume the battery.
