Hello all,
First of all, apologies if this is in the wrong forum.
I have an HTC EVO 4G on Sprint. I am looking for an app that will manage the backlight in a way more like Windows Mobile's own built-in management. Here's what I am looking for more specifically. When charging or plugged in, the backlight should be full brightness and the screen should never dim or turn off. When on battery, the backlight could be set to dim after xx minutes, or not dim. The device should then shut the screen off after xx minutes.
With Android's built-in settings, all I can come up with is the setting for the screen to never sleep when charging, which is oddly placed under Applications -> Development. The screen timeout setting applies to both battery and charging statuses.
Why? When the phone is plugged in, I like to be able to quickly glance at it for time or notifications. I don't like having to hit the power button to check these. When on battery, the phone is usually in my pocket so taking it out and pressing the power button are almost one motion. It saves battery as well.
Also, in the car, I always have the phone charging. I've noticed that some GPS and other programs will keep the backlight on, but others will not. I've seen some applications just allow the backlight to dim, so I have to keep touching the display to wake it up.
Does such an application exist? If not, doesn't anyone else want to see such an application made?
This is one of the little things that I miss about Windows Mobile 6.5.

I am looking for an application that can show a clock with the backlight off. I know it will be difficult to see, but the point is that the lamp doesn't consume power.
Actually, what I really want is that when the power button is activated to turn off the display, the application should start and show the clock with the display turned off, but otherwise enter a low-power mode.
I have no idea if this is possible with windows mobile 6, though.
I just noticed that the Nokia S95 maintains a clock (without backlight) on its display at all times (unless the phone is actively used). This doesn't seem to hurt its power consumption significantly which is why I hope a similar thing can be made for wm6.
Unfortunately, the device can't enter a low-power mode and still run an application.
You can try hooking the power button, setting it to launch your program and simultaneously kill the backlight; but note that your RAM will still be powered, along with any radios you have on (Bluetooh, WiFi), and any background processes will still be actively cycling through your processor.
I have a X7510 (WM6.1 original ROM) and for some reason which I have not set up in any settings, after 20 seconds the screen would dim to 25% if you leave it alone even though I have it set to always be at 100% brightness. It seems it automatically goes into a power saving mode if left alone for 20 seconds before powering off after 2 minutes, which is my configured setting.

Hmm the ram has to powered at all times, right? Otherwise how would the phone be able nearly instantly wake up and show its UI when the phone rings?
Anyway, it is too bad if the screen display anything with the rest in low-power state.
Intesting idea! That would be cool, I have seen it with smart phones but I've never seen it with HTC WM ppc's.
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.
So the screen shuts itself off very quickly. Isn't there any way to let the screen stay on for a while when it is plugged in, and very quickly turn off when it is not plugged in?
So, if I get a text and the phone is plugged in, it stays lit, but if I get a text and it is in my pocket, it flashes on and then off.

"Stay awake"
"Screen will never sleep while charging"
I wish they'd add separate controls, but thank you very much for that find!! And the very curious location it is stored in. If I get a text while sleeping, it'll leave my phone on the whole time - which is upsetting.

It allows you to modify settings based on conditions... I have mine set to turn on WiFi & BlueTooth along with setting the screen timeout to 10 minutes whenever I plug mine in. It also mutes the system sounds after 10pm so E-mail doesn't wake me up, but a phone call will. Worth the couple of bucks for the app in my opinion.
Can your phone automatically dim or turn-off when placed on a table/desk?
I can't use the display when it rests flat on a table as it is too reflective and I can't swype/type/interact unless the phone is in my hand. The default auto-dim seems to activate only if no motion or input is detected. Thus, when I put the phone down, it needlessly burns minutes of battery power before dimming.
If a bubble-level app can detect whether a desk-top is flat/horizontal, why can't the phone dim to save power as soon as it is put down?
Ahah, the solution is a combination of two apps, neither of which work fully. Stay tuned...
Solved!
Tasker allows me to set up a phone orientation (flat on table) in which the screen is always dimmed. Meanwhile, it also allows me to set up more persistent LED/vibrate/flashlight notifications for missed calls, sms, emails, etc. Only drawbacks, the app itself is too expensive/complex/ugly.
Am i the only one whose screen, when it's off, doesn't turn back on properly? It registers both the fingerprint and the power "button" with haptic feedback, and the screen flickers quickly, but doesn't stay on until trying it finally works randomly, or if i use the squeeze gesture to open the camera immediately after pressing the power button. Locked and stocked too.
What is os version are you running?
Does this happen indoors or out?
I used to have an issue where auto brightness would immediately adjust to 0. The screen itself was on but the backlight was essentially turned of.
Only noticed it outside and auto-brightness was on (didn't even think that might be related to the issue! good call. If it happens again, I'll turn that off and see if the issue persists). Running 8.0.0.0 w/ 1.30.617.2 in USA
I have similar experience with my unlocked U12+ and may be Smart screen affected somehow screen back light. I've tried different combinations of settings (automatic Brightness on/off), Smart screen on/off and I noticed lack off problem in dark room. Even though some very strange reactions off haptic buttons (volume down by itself) makes me think about some general functionality problems of this device.
Has anyone noticed whether pressure on a particular point on the display affects the backlight?
When I squeeze moderately strong with two fingers in the area of the padlock (that is seen in a locked screen), it's the same as pressing the power button.
I've been using HTC flags for a long time, but for the first time I've come across such a touch-sensitive device. Every touch wakes him up, even in my pocket, which uses a battery.
I am terrified that there is no separate adjustment of the power and response style of touch-sensitive locations (haptic buttons, squeeze sensor)
