Battery Drain on Note 9 suddenly

[NIZMOZ44]

I am hoping someone can help me figure out what is going on. I was getting 6 hours or more usage for screen on time, and now my battery is draining pretty fast on it's own. Here is my battery usage from today with very little use. Just 1 hour of screen usage. Android System seems to be the biggest issue. Any ideas what I can do with that?

When you got 6 hours of screen on time, was that with pretty much continuous use, or was that also with plenty of idle time mixed in?

bad service?

When it got 6 hours, it was with a lot of use of course.

 

[NIZMOZ44]

bad service?

Nope, 4-5 bars most of the day as shown in the screen shot. I haven't left the house so that signal was the same.

I just wiped the cache partition. Will see if that helps any.

It's defective?

It's defective?

Doubtful

Try look into bluetooth/NFC
I see that you use it, maybe the battery issues are there..

It could be a rogue app.

Perhaps put the phone in safe mode which turns off all your downloaded apps and leaves the stock ones alone which can help to determine if an app is causing this situation.

How do you do that?

If it was a rogue app it would be showing up under the usage pic I posted.

That's if it's being reported correctly by the phone.

I mentioned Safe Mode as this is part of the Process of Elimination processes people use to self help diagnose.

Maybe a Samsung Experience Store or Service Centre will be able to help you further via a diagnostic on the phone.

Thanks, but what does that exactly wipe? And I'm assuming its doesn't delete any information on my phone?

It gets rid of old redundant caches.

It's designed to not delete your own info like a factory reset does.

Sadly we don't have one in 200 miles.

I might try that tomorrow.
