Wow that's not good. Maybe have samsung look at it. Mine is not draining that bad. Mary

 

there have been many threads on battery drain, so many that a lot of us have simply quit reading them.

the generic sense though is, that a rogue application has been activated. One of those is an app that causes the camera.daemon to turn on, but never turn off.

You need to methodically rule out as much as possible.

1st, simply turn OFF as many apps as you can without literally crippling the phone so it can't make/take calls and SMS messaging.

Make a habit of turning OFF both Data and WiFi every time you lock the screen. I do that automatically with MacroDroid and can tell you that it works big time. My phone is on Day 3 w/o being charged and the battery status is 51%. I make a few calls a day, I look at the weather, I read the news, I visit the forums a bit... but when I shut the phone down (lock the screen), MacroDroid turns off data and wifi.... works like a champ.

You might not like my method, that's okay.

But, you need to isolate what is going on, and turning off the internet every time the screen is locked will certainly isolate a world of "what ifs"..

Okay, all the extra apps are turned off. And now your battery is doing great.

great, now turn them on 1 at a time and monitor to see which one is killing the battery....

I have a hint, anything with the name Amazon in it is Dead Meat on my phone... horrible battery muncher that app is.

I had this issue wherein android os is the no 1 cause of battery drain (could go up as much as 50 to 80+ percent). I don't know if this can help but what I did was to restore factory settings and deleted everything. Then I didn't restore my files but monitor it for a few days and my android os dropped to ~5 percent. After knowing that my phone is stable, I reinstalled my apps one at a time while monitoring for few hours each time before I added a new one. So far my problem was solved. Give it a try. I am sure one of your installed app is causing this.
