Backlight staying on after pressing power button

So it seems that my phone backlight stays on at random times after pressing the power button to turn screen off. I don't notice it in the day because the background is black, but i've noticed while using my phone at night that the back light stays on. I can't recreate the issue, it just happens at random times. Doesn't matter what ROM i use, it still did it with all roms. Does anyone else get this problem? The reason i say problem is because it drains the battery quickly when the backlight is on. It can go from 60% to Dead in less than an hour.
Currently running stock rooted 2.3.6
Screen is at lowest brightness
I Always press the power button to turn off screen when i'm done using it
I have screen timeout set to the lowest (15 seconds)
Any ideas?
I had this happen once when testing out chainfire3d. Restored a cwm backup and haven't seen it since.
got same problem once
When i had this prob, i was running RootDim @ background, so make sure u are not running any LCD brightness modifiers at the moment.

screen dims few seconds before it shuts off.

Maybe its normal but I have smart stay on so if i am looking at the screen it dims but doesn't turn off. This happens even with auto brightness, power saving and auto adjust screen tone turned off. the browser also has auto brightness turned off. the only thing i can think is maybe there is a conflict with quick settings which also has auto brightness turned off. if i am not looking nat eh screen it dims and in a few seconds shuts off.
what mine does...
Same here. I even start blinking and moving my eyes to see if it will stay on. I know I've got to look like an idiot.
Currently not being productive on my S3.
I have been playing with smart stay as well, but I haven't seen that it keeps the screen on any longer ... maybe I just haven't had enough patience.
smart stay does keep my screen on but it does not prevent the screen from dimming. I think the phone automatically dims right before its about to shut off even if i have all dimming settings turned off. right before it shuts off smart stay keeps it on but only after the screen dims thus i am stuck with a dim screen.

[Q] Dim screen less?

When my screen dims after inactivity, it dims to the point where I'm actually thinking the screen is off. Is this a setting I can change.
(Not the time out, but how dim it actually goes?)

Screen dimming after wake up from sleep?

I don't know what it is but my Z3 is getting dimmed a little bit after I swipe to unlock. When I press the power button, the screen turns on with a bright wallpaper, after I swipe to unlock, the screen dims like 5% brightness immediately, but in some cases several seconds later. Because the lock screen is the same as my wallpaper, this issue is very obvious. I have turned off auto brightness.
This is not so bothersome to me but it's strange? Any ideas?

Doesn't do that on mine. Do you have any power saving features on ?
Aside from auto brightness I can't guess what would do this.

Help! Z3 screen is dim and will not brighten up.

I have had my z3 for a couple months now. Yesterday the screen dimmed down significantly and will not brighten back up no matter what I do. I have turned of "Auto Adjust" and all that. I have manually increased the screen brightness to maximum and it does not thing. The current brightness is good enough for indoor use in a area with not much light, but in a bright room or outside I can barely tell what is on the screen. I have powered the phone off and restarted it several times. It's like it is stuck in some kind of battery saving mode that it won't come out of. I made sure that all battery saving modes are turned off. Nothing effects the screen brightness no matter what I do. Please help!

Does it happen in safe mode? (Long press power button, long press "power off" text, ok). If it doesn't, some app is responsible. Last resort would be to do a factory reset.
