Viewing a clock with backlight off? - General Topics

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.

turning off the XDA EXEC

Hello
How does ont turn off the XDA EXEC, i dont see any off button. the power button just turns the screen backlight on and off.
the reason why i wanted to know what it was is because i am porting my number across networks, and 02 told me to turn off my phone a number of times during the day, so that it could go into a boot up process.
There is no real way to trurn the device off, but what they will be wanting you to do is disable the phone section (do this by turning on flight mode, or by clicking on the green connections manager in the bottom and click on the phone button. Click the phone button again to turn it on.)
Start -> Programs - Wireless Manager -> All Off (This switches of the phone.
Then use the phone on/off button at the top of the screen there, to switch it back on and force your SIM to re-register with the network, which should have the desired effect your after.
Taking out the battery is the only real 'off' button.
thanks for the replies dudes
did you try holding the power button as well? that works on my wizard
not sure if it's true for all wm5 though
i held the power down button for some time and it blanked teh screen. when i held the power button again for a few seconds the screen came back to life, but this time there is no "back light(?)"
how do i get back the "back light(?)"

There remains a bug, it seems, that sometimes prevents the backlight from firing up when starting the device.
It used to happen on my XDA2i and still happens on my Exec.
I usually have to get it in a good light and go to settings and move the brightness slider to get it working.
Turning off the device, I find, is actually achieved by pressing the power switch before closing lid.
I find I get much more out of each charge if I do this rather than just close the lid.
That of course turns of the PDA functionality of the device. The radio (phone) service is still disabled via Flight Mode.
:wink:
somehow i double posted...sry
thanks for the reply
i guess by pressing the power button, the pda goes ito some sort of sleep mode, since it does not boot up later, correct?
when it is charging up using a usb cable connected to my pc, the backlight is turned of, and no amount of pressing buttons seems to turn on the backlight, is that correct?
i checked out the brightness level sliders, there are 2, the
1. on battery which is somewhere in between
2. on power which is "slided" to the left, is that its correct position?
you will probably find it will selfboot at midnight.. this appears to have been intentional in the design of all the XDA's.
Thia can be a nuisance but it is probably to do with reseting timers. alarms etc
The backlight is configured to be on/off during external power and on battery in which ever setup you choose.
The actual levels you set it at are your choice ..
I set mine to be off after 5 mins on external power i.e. when charging except when i use tomtom and want it to stay on whilst externally powered.
On these occasions I change the setting before the journey
Your original question with reference to O2 making changes that required you phone to be off, in my experience, means not having the O2 sim in the device.
thanks for the reply dude
i think my questions have exceeded the remit of this thread. i will start another thread for the backlight questions

Jasjar Power Button not powering off Jasjar, just turning screen off?

I have WM6, but i have noticed, i can't power off the Jasjar unless i pull the battery.
If i hold the power button it turns the screen off but the unit is still on, have downloaded psShutXP and this does the same.
Am I doing something wrong or missing something, when flying you can't have the unit on, even if flight mode is activated.
Checked and searched everywhere for software etc to try resolve this but no luck!!!
Can anybody help please
Tks
yes and no
Hi there,
You correctly turn of the screen with the powerbutton. Thing is, you do not want to power it down. Because powering the unit down might cause loss of data (when you turn it on you will get a blank device). The rom is powered by the battery.
So, flightmode is sufficient for flying an airplane. All you need to proove is that all receivers and transmitters are turned off. (phone, bt, wlan).
Should you really need to power it off anyway, i´ve found no other way but to remove and reinsert the battery.
good luck
daniel
pressing the power button briefly, turns the phone onto standby mode.
pressing and holding the power button, turns off the display backlight only.
setting the phone on Flight mode, shuts off all radio activity, and is sufficient for inflight usage.
there really is no good reason why you'd wanna switch off the phone completely, but if you insist, then as you expected.. pulling the battery out is the only way for now.
i wouldn't do it anyway, as it might lead to data corruption and other issues (kinda like if you pull the battery out of your laptop while it's on standby/power saving)
You cannot completely turn off the device.. it is part of the design.
What you want to do is not a good idea. No developer even bothered figuring out how to do it, due to the mentioned side effects of losing data.. hence there is no app that can do that.
maybe when time comes, developers may come up with a hibernate mode -- saving data into the sd card

With devices like the Universal (and most other WM5 & WM6 devices), pulling the battery won't cause you to lose data - it just acts as a soft-reset. (Although older devices, eg the Alpine, if the backup battery died as well then you'd have a hard reset)
If you are going on a flight just set it in flight mode, and turn off the volume, then put it in its "off" mode (ie hit power). This should be enough for most airlines. If you are really worried, then just close all the programs running and drop the battery
Well, didn't expected a huge response.
Thank you all for your feedback and info. I had a Jamin before and you could turn that off with no data loss, therefore thought the Jasjar could do it as well.
I just thought it was my unit since i loaded WM6 onto it, but it iseems to be the norm.
Will live with that, bit annoying having to pull the battery thou to turn the device off.
Thanks

WM5 Configure Power Button to turn screen off, dont suspend????

How to configure button power for only turn screen off, dont suspend???? Because my device have issues with GSM when in suspend mode.
.................
..........................
Aren't you confusing something?
* On: The user is interacting with the device. Everything is on.
* BacklightOff: There has been a brief period of user inactivity (no one has pressed any buttons or touched a touchscreen). The backlight has been turned off, but everything else is on. When you set the backlight timeout values in the control panel, you're setting how long the system should wait before going into this state. (Note that this state is new for WM 5.)
* UserIdle: There has been a longer period of user inactivity. Both the backlight and LCD have been turned off. When you set the screen timeout value on a Smartphone control panel, you're setting how long the system should wait before going into this state. This state is generally not used on PocketPC. There's no reason to turn the screen off when the device is about to go to sleep (sleeping turns the screen off). However, if/when PocketPCs go to the "Always On" model, they'll start using this state.
* ScreenOff: You go into this state when someone specifically says to turn the screen (and backlight) off. For instance, in Media Player you can assign a button to turn the screen off. When you press it, we go into this state. This state is different than UserIdle, though. This state says, "The user wants the screen off and doesn't want it to turn back on." UserIdle says, "The user hasn't touched any buttons in a while, so we might as well turn the screen off to save power." In ScreenOff, pressing a button (other than the power button) doesn't turn the screen back on. In UserIdle, pressing a button does turn the screen back on. Both PocketPC and Smartphone use this state.
* Unattended: This is a confusing state in which the screen, the backlight, and the audio are off. I won't go into too many details, other than to say that this is a PocketPC-only state that is used by applications which need to do things without alerting the user. While the PocketPC is in this state, the user thinks the device is asleep. For instance, ActiveSync when it syncs every 5 minutes. It's waking up, syncing, and going back to sleep, but the user can't tell.
* Resuming: This is the state the PocketPC goes into when it wakes up from sleep. In this state, the screen is off, and there is a very short (15 second) timer before it goes back to sleep. The only way to keep the device from going back to sleep is to have something put it into one of the other states. This is really for dealing with spurious wakeups and for giving the system a way to get into Unattended without letting the user know about it.
* Suspended: This is the PocketPC "Sleep" state. Everything is off, and the system isn't going to wake back up until some piece of hardware wakes it up. It's not actually an official Power Manager state, the way the other six are, but I'm including it for completeness.

When you hit power button once, you go to Screen Off (Sleep). Suspended is when your device 'completely' off.

[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.

[Q] Backlight Management App

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.
