S25 256 battery drains 35% overnight with no app usage

[Members_YHGWr9l]

It has been a week only with this new phone. My battery was at 70% before I slept. I switched off wifi, data, location and turned on power saving mode. There are few apps like telegram that I even put to sleep. Deleted all routines. AOD is turned off. Disabled all good lock features. 

The battery in the morning is now at 33%. When I check for the apps or processes that drained it, there's none. 

How can I fix this when I can't understand which app or processes is eating my battery all night.

Have you reboot or restarted your device recently. Sometimes just a reboot can help with issues. Hold side key with the volume key simultaneously until the device shuts down. Wipe the cache partition in recovery mode and run Good Guardians app booster. Seems you are doing every thing right with saving battery over night when it comes to putting apps in deep sleep. Using battery saving mode and turning location off. I turn of mobile data and leave WiFi running. A bad network signal can cause drain.

I have the same phone. I set a bedtime routine which turns off all stuff like wifi, mobile data, location etc. I also have nealry all apps in deep sleep. My overnight drain is c. 4%/

Normally, new phones do the same. One trick that works for me. Drain battery till zero or at least 1%, then charge phone to 100% . Hope it will solve your battery problem.

I wonder why we have to do different things to figure out a solution when samsung claims AI capabilities. There is no diagnostic within the phone that shows an app causing a problem so that I can deal with it. There's none. Never had such problems with iphones. Is this something I can show as a defect to claim warranty ? Perhaps could be a problem with the battery.

The network signal was good. I switched off the wifi so that no app works. I wonder what settings the youtubers use to get 6h or screen ontime. I barely get 3.5 hours without youtube. I can't understand why a user has to try all this. Surprisingly no diagnostic to reveal what's eating my battery 😆😆😆
