Battery life on android 9 was far better than android 10. I'm not even getting 4hrs of SOT.

You battery need calibration. Best thing is let you phone discharge battery fully then recharge to full 100 percent. This cycle will re calibrate you battery and petformance will improve. Also during night put your phone battery to medium optimization. In morning you can switch back to optimized. Hope this solution helps.

after android 10 update, if you haven't reset your phone then please reset it . If possible hard reset it . It will make your phone more smooth and lag free . You will see improvement in battery life too

Battery drain was horrendous on Android 10, only got 3 or 3 and a half hour SoT.

Tried wiping cache

Tried factory reset

Tried changing the battery saving modes

 

Although phone was running smooth, but in relation to the battery nothing helped. Over the weekend I rolled back to Android 9. Finally I have a solid battery again and all the issues gone away.  

 

I do think Samsung has massively dropped the ball with Android 10 upgrade killing the awesome battery performance of this phone. I am not likely to upgrade to Android 10 any time soon
