I changed from MIUIPolska/Xiaomi.eu because since Autumn weekly updates my phone lasts 0.75 (bleutooth bug) to 1.5 days... I was pissed off because earlier I had charged the phone once for a 4-5 days... Now I'm on a first run, but after a night battery drop was 6% ( MIUIPolska/Xiaomi.eu was 25-40%). Now after about a day it's 89% (some net over wifi (~ 30 min), one call, a few SMS). I use both (dual) SIMs. I don't understand why we can not achieve SOT like Redmi Note 4. It's the same hardware and battery...
I've got another question - could you integrate aptX support into ROM ?
Update: I'm now 1 day 19h, SOT so far 5:34h, Bluetooth 3h, about 2h of talking, a few sms - battery is 48%...
Maybe 9 isn't worse than 8, but there is problem with DATA. Maybe not all updates were well prepared and the only way to correct this is to wipe DATA?! So far Epic ROM gives very good battery life ( I believe in 3-4 days and SOT ~ 11h).
Update: 2 days 19h, SOT 7:22h, BLE 5:24h, twice GPS about 25km + Spotify, 3h of talking, a few SMS - 18%
Update: 3 days 10h, SOT 8:29h, BLE 6:15h, 2.5x GPS about 25km + Spotify, 3h of talking, a few SMS - death.
