Super fast battery drain on Note 10+ post One UI 4.0 update

[tanyrug2525]

I updated my phone to one ui 4.0 last night (12/01) and had full charge when I slept, woke up with 74% charge(barring alarms) but now it's 12:20pm on 13th and with minimal usage it's on 21%. There seems to be a huge battery issue with the new update. Anyone else feeling the same? I would like to add that my phone is active since September 2019 but I have reservations with the battery replacement since it's about 9k on the Samsung site

i am fine with battey performance on s21 ultra after oneui4.0. its almost same no significant difference. you should check for the app consuming more battery and put those to sleep mode.

Hey I've checked and even run a diagnostic test but no app currently is having any heavy usage as such

It will happen for a week. But its better to clear cache partition and reset settings at least.

Hey I'll check that out

I think it is a huge bug of One UI 4. I hope Samsung fixes this issue very soon because the battery is draining super fast in your case. And please visit device care, and check which app is draining the battery. Put that app to deep sleep.

Device care doesn't show any app with heavy battery usage actually, it seems to be a bug

Then clearly its a bug. It is expected in New software. I think the only option is to wait for next update. OR, u can try resetting your device

[tanyrug2525]

Yeah I'll probably do a backup and reset device
