Massive Battery drain

First Poster

My Galaxy Note 9 with medium power saving mode would have above 24 hours estimated battery life at 100%.

However recently idk why it drops to about 17 hours++. Is my battery damaged? Or did i accidentally enabled some features that makes it drained so fast. Anyone experiencing the same problem recently?

Have you been able to check in your battery stats section in your phones device care / device maintenance section @Zy  to see if something is highlighted.

 

A good tool to see if a downloaded app is causing this is to put the phone in Safe Mode which disables your downloaded apps and leaves the stock ones working and then see how your battery behaves. 

 

Location based apps etc can use more juice and its possible one or more of your apps are not going to sleep / dormant when not in use.

 

A Samsung Experience Store or Samsung Service Centre can run a diagnostic test on the phone for you too.

Check battery info if there isn't any process which concumes too much battery.

Next you can use this application to detect which application wakes the phone on: Wakelock Detector [LITE]

I wrote recently an article about it here but it is in czech language. You can try translate the article to english...
