S21 FE overnight battery drain **bleep**

[PKsamsung]

Without turning on Bluetooth, Wifi, Mobile data, location overnight, My S21 FE battery drain is about 4-6 percent in night. Even i use phone on dark mode eye confort shield extra dim in night. After one ui 5 I have reset my phone also but. Its happening after one ui 5. 

In one ui 4, overnight ideal battery drain was 2 percent only. 

After one ui 5 , battery drainage issue not solved even more battery draining whole day I have to charge 3 times a day with SOT 4-4.5 hours.

I charge twice in a day, Sot ranges from 4 to 4:30hrs, but overnight drain is 1%
Have you put app to sleeping & deep sleep?

I too had a same issue of battery drainage in night with only mobile signals on & no apps on background

switch off the phone at night...will drain only 3% 😂...serious battery issues with this series...seems Exynos is more efficient than developers

Only way that worked for me is to turn the airplane mode and nothing else. 

Before i would lose like 4% or 5%. With airplane mode, I don't lose even 1%.

Good question is should you turn it overnight? For me it's crucial to stay on so yeah.. It **bleep**.

I wonder will Samsung start to take care of their consumers. Battery is terrible, no AOD animations.. Probably the last Samsung phone I'll buy.
