Screen usage is killing battery

[Jezza819]

A co worker of mine has a S6 and is having trouble with the screen randomly coming on and going off. As a result I think it's killing his battery. If I look at his battery stats the screen is sitting on 32%, Messenger is at 16% and Facebook is 13%. That's the three biggest readings and all others look normal. What's happening is that the screen will just pop on by itself, stay for 4 or 5 seconds, turn off for about 5 seconds, then come right back on and stay for 4 or 5 seconds. The cycle keeps repeating itself. He says that it will do this sometimes for 4 or 5 days in a row, then not do it for maybe close to a week, then it comes back.

I thought he might be getting some sort of reminder from something that is turning the screen on but then it doesn't make sense that it goes right back off again. Since it's not my phone I can't get any screen grabs or anything.

Any ideas?

Find the app or what ever is causing the screen to turn on and kill it.
Wipe system cache.
Factory reset and slowly put apps back on looking for the one causing the original issues.

How can I find out which one is causing the screen to turn on? Just wait for one to start turning the screen off and on?

First wipe system cache via recovery.

Second, have them boot into safe mode and make sure it's a third-party app and not a system issue.

If it doesn't do it in safe mode, I'd suggest to uninstall last few apps that were downloaded. Keep doing so till the problem has stopped. Add apps back one at a time till you figure out which one was causing it.

If it still does it on safe mode -or- if you have uninstalled all third-party apps and it still continues, I'd now suggest to go ahead with a factory reset.

It might be that he's just barely in range of a Bluetooth device so it keeps connecting and disconnecting

What will wiping the system cache delete? I would have to make sure that he is ok with doing that along with a factory reset. I've never even attempted that on any of my own phones.

Just in the quick look through I did on his phone he still has a lot of the factory bloatware on there like the games and such that Verizon likes to stick on there. What I thought about doing was going through and disabling all of those stupid apps.

Wiping the system cache will not delete any of his personal data. ITs like clearing browser history. Pre loaded and pre fetched info is removed. So after its wiped the device boots up and starts all the apps that the device uses and loads whats necessary to function.
