Guys, I installed a few apps recently, and now it seems my power always stays on, even though the screen and backlight turn off. This makes the device burn through the battery in 4-5 hours instead of days. How can I find out which app is causing this? Any idea?

Hey guys I notice sometimes one every month or so when I turn off my phone (standby mode, not hard or soft reset) the phone is still on however its a black background (backlight)
What causes this error to happen? the only way for me to get rid of the backlight issue is by pulling out the battery and turning it back on.
i am having the same issue and it is draining the battery! i hope someone figured this one out
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.
As the title suggests, sometimes when my tf700 has had a long period of being idle if I go to use it and press the power button nothing will happen. I can still hear it functioning though cause I've accidentally taken screen shots when trying to reboot it when this happens, the screen is just black and I have to reset it.
Any suggestions?

Try switching WiFi sleep off and see if it helps.
Wifi sleep off?
I have that happen to me more than a few times. I just end up hitting power button and just tapping the corner. It works sometimes. but it's not always faster than just rebooting. Although, if you're going to reboot, just hold the power button till device shuts off.
What I think is happening is not that it's not waking, the display is just not turning on. I noticed this by plugging in the charger, which always turns on the display and device.
Yeah, the display isn't coming back up. I've noticed that too because I can still hear events occur (ie: unplugging the charger).
Another user on here tipped me off that it could be that it's in power save mode and the dimmer is COMPLETELY down, if you bump the brightness dimmer up just a hair, even 1 notch, it'll stop it from doing it, or at least it's stopped it so far for me since I changed it.
Why start two threads on the same issue?
I noticed that if i leave the screen on (with gravitybox) for a mid-long period, e.g. 30/60 min, the display will start flickering (or jumping) and the oscillation will increase with time. The only solution is to turn off the phone and let it rest for some time then power it on. Do you know why?

I am not sure if mine is related, but today my Nexus 5's screen flickered then went black. I can feel the phone vibrate when holding the power button down. But still nothing, tried plugging into computer and after unplugging I hear the low power chime. So I know that it is working aside from the screen staying black.
The phone is running 4.4.3 stock that I flashed via twrp, with faux123 18u kernel, exposed installer, gravity box. This could all be coincidence, and I could just have a bad screen. But does anyone have any suggestions?
Yesterday the phone did not wake me up, holding the power button it directly booted up again, just like it was turned off.
The battery was charged at 55% and there was no update in recent days, so I doubt its a software issue.
The same happened today as well... This is starting to bother me.
Is there any way to find out why it shut down ?
Don't know how to help you with finding out what causes the shut down but I'd check the "planned shut down/turn on" option in battery settings. Even if that's not it you can try to use it to force the phone on before your alarm goes off.
