Sot Time


Never had such low sot. Managed even 2 days between charges with 6h sot. Standby drain was worse initially(more than 1%per hour, I think), but got better with use time. Never had less than 4h sot, not even while navigating.
 
It's too early for hard conclusions, but last night I delete miui and android data folder from my internal storage. It seems that battery is much better now!
 
I got bad SOT, after too much tweaking and dirty flashing. Now I will see after clean all the thing, format all data (include internal storage), and flash latest ROM. Normally it will get at least 4 hrs SOT (from 100 - 20%). If push to 10% maybe can get 4,5 hrs, but it's not good for your battery. Keep it above 10%
 
Last 2 or 3 weekly updates were not good for my battery life. Used to get 6h sot with earlier MIUI 9 versions, now it's about 4h. Standby drain is also higher.
