It shows up in BBS in the kernel wakelock and usually shows up when i've missed a call. It drains the battery pretty darn fast and keeps the phone awake.

I found this earlier, could be helpful. supposedly that may be a collection of different wakelocks from what I found. Check out the links and I would recommend running your phone is safe mode for a few hours to test and also running normally and freezing some apps. Hope that helps.

Maybe you're right... i didn't explain that, because in BBs it shows me 1s but not in WLD???????

It appears, only when i plug my phone on charge (or usb), and use the torch in the background...
Did you find out what that powermanagerservice.Wakelock was ? I'm having the same issue ATM on my oneplus one and don't find any solution...(I know I'm on the wrong forum but i think its not device related)

So, did anyone find out how to fix this?

I'm having the same issue on LGG3 (5.0 stock, v21a, rooted).
Phone's battery is discharging much more rapidly than before (for couple of weeks now), even when the phone is not in use at all.
2 highest wakelocks are PowerManagerService.Display and PowerManagerService

I thought the PowerManagerService.Display had to do with your display on-time. From what I understand you can at least assume that your display is supposed to consume a lot of your battery power. In that case.. Some unfounded guesses: (1) try manually adjusting your screen brightness instead of automatically, (2) keep your brightness as low as possible, (3) disable as many fancy lockscreen and launcher visual effects as you can.

If the PowerManagerService.Display actually does refer to the screen-off state, maybe look into the way your phone displays notifications?
