The device is running android 8.1.0 feb 2019 security patch that came preinstalled. I haven't updated it yet. Please help me. And which firmware till now is the most stable one without any bugs & battery draining. Please reply 🙏

Before start of this cycle I have completed -
1.Battery recalibration - No Result
2.SMMI Test - All test passed successfully.
3.Battery charging discharging in safe mode - Overnight battery drains to 69% ( Attached screen shot for your reference)
Is it firmware issue ? (Attached screenshot of latest updated firmware)
If yes, I have 2 same handsets of MaxProM1,32GB & 64 GB - HAVING ISSUE.
32 GB is working fine with same firmware.
Pls guide...

if it is not fixed after update
do these things in night backup apk of these apps and uninstall or disable all the google apps like google,google play service ,g map,play store , chrome ,,, facebook , messenger and enter safe mode ,,
even after doing these things ur battery backup is not good then there may be hardware problem
