Please take a look at my earlier post.
By "96 hours" I meant in overall working phone with idle time with screen OFF too. Now, no matter if I use phone or not I need to charge it every one-two days. Before it was ~3-4. I didn't mean SoT=96h which is unfortunately impossible
I wonder about your 10h SoT and what thing is wakelocking my phone. Bluetooth on all the time (for mi band)? That's why I provided screens from BetterBatteryStats app in that post. Maybe it could help?
My battery is not so degraded, ~80% of the original capacity remains.
And about speaker volume:
I didn't know about that, I though there is no controll for speaker volume.
With new default value=-10 I hardly heard the interlocutor and I haven't any problems with deafness (yet). That's why I thought it's bug (?) and wanted to report it.
Now 80% by some software? Nothing can determine the actual capacity of battery. It's Chemical reaction not some code . So 80% is highly questionable.
Increase -10 to 0 if you want no body stopped. Now I get 12 hours sot in this ROM. In MIUI app 8 hours. So my tests and other users results say. 1.5 times battery life.
