Last night I took my S22 Exynos out of charging before I went to sleep. I woke up in the morning to find 40% of my battery DRAINED.

I'm really frustrated with this S22 as idle battery drain in general with screen off according to Accubattery is 5% PER HOUR. My S22 does not enter deep sleep overnight or during the day.

I opened ADB and looked and noticed a LOT of screen wakeups when I was sleeping and the phone was not charging.

It appears the phone keeps thinking it is plugged in when it is clearly not. I wonder if this stops the phone from going into deepsleep?



I have my brightness set manually (20%) and noticed that the wakelock for screen_brightness is running.

ADB command: .\adb.exe shell dumpsys power



Please help. I am truly at my wits end with this phone. Battery drain is insane.
