Backlight does not turn off/effecting battery life - HTC Vox

I've checked my power settings and based on them my backlight should shut off after 1 minute of non-use.
When my phone is idle, or when I lock it the screen light only dims but it is never shutting off completely! This has caused a dramatic shortage of battery life.
Any suggestions?

Power always stays on

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?

Backlight problem

Hi,
I've got problem with my Vox: when on battery, backlight is randomly switching on after some time (few seconds to about few minutes) - even after display switching off. This significantly reduces time on battery - with fully charged unit, it took about 7-8 hours to have 50% charge.
I've tried different display settings in registry and few roms with WM 6.0 and 6.1, it still happens though.
When I plug in cable/charger, phone behaves like it should (display stays off as long as I don't press anything or unlock the keyboard).
What could be the reason of it?
Best regards,
niski

Battery drains out quickly, phone turns on automatically!

Hi!
I have a very big problem with my HTC.The on/off button doesn't work at all, battery drains out after few hours and phone turns on automatically when I put the battery in. What can I do?

[Q] Sleep option in power menu

The sleep option in the power menu, is it any different than taping the power button to to turn of the screen? (or letting the screen time out)
Sleep mode on a computer is a true low power state, does Android support this? I know that when the screen is off on my N1 that the OS is still running, because it has to for proper function as a phone. Now the Gtab does not need to keep running when you shut off the screen, so a true sleep mode would be great.
I have selected the sleep mode before, and to me it did not seem to take any long to "wake up" when I tapped the power button.
I think that if it is a true sleep mode, then it would be nice if we had options like a standard computer. Set the screen time out and then a separate time to enter sleep mode automatically when there is no user activity. Have it function like that when you tap the power button as well, auto sleep mode after 5 minutes or so.
It's the same as tapping the power button. Try to charge the battery full, and put it to sleep mode overnight. Do the same thing for tapping the power button. I've done this and next morning the battery is still at 100 percent full.
The battery indicator is slow to refresh upon waking back up I noticed, I guess experimenting could show if there is any real difference. Still , I would like to know from a deeper perspective, If the source is ever released someone with more knowledge than me could examine the code.
I too was wondering about the affect of sleep vs auto timeout on battery life, so I put my TnT Lite 2.0.0 to test:
(1) with sleep: after 12 hours the battery meter drops by 17% (I actually did this twice and got basically the same result)
(2) with auto-time out: after 8 hours the battery meter drops by 12%
So it seems that sleep and auto-timeout have the same affect on battery.
I am surprised to hear in post #2 that there was no change in battery life; after all, the CPU still runs, albeit at a lower clock. I do notice that when the unit comes back on -- from sleep or auto-timeout -- it takes a few seconds before the battery meter updates itself. Maybe that's the reason why in post #2 it looks as if there's not change at all?
In any case, I can live with dropping 17% over 12 hours, esp since wifi reconnects within seconds. The more I use the g-tab the more I'm amazed how well-built it is as a piece of hardware, and how much it was weight down by the stock TnT... Thanks to roebeet/rothnic/bekriebel et al for making this useable (and fun!).
I do not think the CPU runs on a lower clock when the screen is off, that is why SetCPU has the option have a profile to lower the clock with the screen off.
If we can get SetCPU to work correctly, this thing would hardly use any battery if set to minimum clock speeds.

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.
