I find that when you "close" program with HOME button, it will go to background and enter S - sleep state, but wil have higher priority than other programs in background (400 instead of 500) and CAN USE some cpu cycles. For example program called Network Monitor. When you run it.. it is showing graph of network speed. And when you enter HOME button, it will disappear, but through task manager you can see, that it is still using 5-7% of CPU constantly. I have read in thread about task managers, that programs in backround don't use phone resources... this is not really true. (yes programs, i don't speaking about services. I'm speaking about network monitor GUI, not service!)
But trick is, when you "close" program with BACK button. What happen? Program goes to background and enter S - sleep state, but program priority is now normal as in other background programs = 500. And in case of network monitor, now it don't use any CPU cycles.
This is not only about Network Monitor, some other programs closed with HOME button uses CPU in background too, but not constantly and only around 1-2%.
So if you can, close program with BACK button. This is little impractical of course, because BACK button have in programs another - back function, and you will need push it more times.
-sry for bad english-
I see same memory usage if I close application with back or home button..
I just hit the "back" and "home" button a couple of times...then again...I have compulsive habits

hi folks,
every time I use tomtom for navigation and want to turn off the display to save battery power, after turning on again tomtom is closed.
the same happens to all other applications.
do you have any ideas why this happens? do you have the same problems?
greets
I am not seeing that behavior. If I hit the side power button briefly to cause the 3300 to go to sleep, once I hit it again, I am brought to the Today screen but TomTom is still running albeit not at first visible but I just have to hit either the tomtom hardware button or the icon in the taskbar.
Same applies for other applications that are running and I put the PPC to sleep.
I have Tytn with wm6 oficial from htc and sometimes the buttons doesnt work. The messages button, IE, Green One, Red One, but the keyboard works everytime. If I turn the phone off and than Turn it on they work for a while. Is there anything I can do to resolve this problem?
Thanks
same problem here...
or when Ichoose to wite a new next message or to read it, the screen flashes back to the home screen and then takes me where I want to go in a couple of seconds.

Hi,
I maybe wrong but so far I think I've nailed this down to task managers installed by either the rom developer or the user that normally aren't in the base rom.
Examples: spb mobile shell, spb plus, possibly even htc task manger.
reason: if you notice spb plus has a Red X option for closing applications when you tap the X, instead of minimizing them to the background. it also brings up a quick menu if you hold the stylus too long on a scroll bar and are scrolling a page slowly using the stylus. if you have this menu drop downwhenyou lift the stylus in that brief period that you do to put it back at the top to scroll further you may end up accidently taping the close application that shows on that menu. it can be triggered by other means on screen and maybe behind the problem.
I've had similar since I run both spb mobile shell and spb plus and have been too lazy to disable the task managers since the schaps rom I run now already has htc's task manager in it by default and is loaded on boot.
try disabling all task managers the show one the top task bar and that recognise screen gestures.
*thank god for full qwerty keyboard on this hermes as i've already done 2 posts today and were this an artimis i' be crazy or not post when I'm out and just relaxing in car in the morning due to artimis doesn't have a mechanical keyboard only onscreen hahaha*
I wanted to know if I was using wasted resources by using my direct key mapper to map the Power button to the "Lock Device" App. Whenever I hit the power button, it runs lock device and I get the "slide 2 unlock screen" When I hit it again, it puts the phone in sleep mode. Is this the best way in terms of being using resources to lock the device? I have no problem hitting the power button twice to put the phone to sleep...Just wanted to make sure it wasn't running the program over and over again. I feel that this is a much better solution then installing a keylock program to do this.
Have you given the SmartLock utility a try? It utilizes no cpu or RAM resources. This way you don't have to press the power button twice every time.
Regarding, your question, maybe you should just try it out for a day or so. If you notice your battery life taking a toll, then it's probably not a good idea.
It seems to be eating up my CPU from time to time.
It just most recently happened when I I put my camera and took ONE picture, then I just pressed home button, and all of a sudden Watchdog alerted me it was using ~50% CPU. I then removed open apps (by holding Home button and tapping Remove All), and a couple seconds later it was back to normal. This isn't the first time either... There have been times before where I wouldn't even use the Camera.
Also, BBS is showing the most wake-ups is google.android.gsf. What is this? I know it's Google Services Framework, which sometimes is on top list of cpu processes, but what exactly does it do, or which apps use it?
Any ideas?

Sometimes in poor lighting Smart Stay doesn't work. Wouldn't if be more battery efficient to disable screen timeout and Smart Stay and just manually turn the screen off with the power button when done using the phone?
My theory is ideally, for battery and ease of use, would be to have this combination (assuming you are diligent about turning the screen off manually of course.)
1) Disable Smart Stay
2) Turn Auto Screen Timeout up considerably to 5 or 10 minutes. This is assuming I don't need it to stay on longer than 5 or 10 minutes but still gives you a safety net if you forget to turn it off. (This is also assuming apps like video players are smart enough to keep the screen turned on - otherwise you would have to keep waking screen if say you were watching a movie in a dark plane cabin.)
3) Turn off screen when done using phone.
What's nice is even if timeout is set high to 10 minutes if you answer a call, screen still turns off automatically when bringing phone to face.
Second method:
1) Disable Smart Stay
2) Set timeout to 15 or 30 seconds.
3) Have some sort of button press to force screen on indefinitely, or ideally you can set it for a max amount of time like 10 min, like double press of power button? Is there an app to do this?
I think first method would be most battery efficient if you remembered to turn the screen off every time, second method is 'safer' Is there an app or stock setting to achieve second methods?
Guess I should try Screebl
https://play.google.com/store/apps/details?id=com.keyes.screebl.lite&hl=en
I'd still like an option to do a double press on the power button to force it on indefinitely.
Meh. Not liking Screebl too much for two reasons. Makes phone stay on while in my car or pocket if I forget to turn it off. But, if I am as diligent about manually powering off, it shouldn't make a diff, but, it will. Reason is, it complicates operation when you want to change a song now you have to manually turn phone off while driving after changing song. I suppose once I have bluetooth setup in my car I can have Llama disable Screeble when I have bluetooth car connection. Also don't like that there is no option to not have the notification bar icon.
In a 2 min GSAM test with phone just sitting at angle, it took 1% battery. Wonder how much Smart Stay would take. Maybe BBS will give that info?
Really still think best solution is to map double press of power button to disable screen timeout until power button is pressed again. That's all I need.
Getting closer. But unfortunately, there is no (hardware) search button on S3! Need this for long press of menu or back button?

Got it....
Screen Timeout Toggle
https://play.google.com/store/apps/details?id=com.chemdroid.screentimeouttoggle
Then for those using Nova Launcher
Settings > Gestures & Buttons > Long-press Menu > Apps > Screen Timeout Toggle
Now I can just long press menu button to toggle if screen is forced on or not. I'm actually having second thoughts about turning off Smart Stay though as I don't know for sure if part of the time I've been setting my phone down without pressing the power button! Guess I'll see...
