Power consumption, Suspend vs. ScreenOff - JASJAR, XDA Exec, MDA Pro General

Hi all,
Can anyone shed some light on this question? How does power consumption differ between always suspend the UNI versus always ScreenOff the UNI, is there a big difference?
P.S. ( Does any one know how to make the middle button become the power on/off button? I tried AEPlus Button and it cannot remap the power switch)
Thanks!!!

During suspend mode, most of the non-essential hardware is turned off (e.g. SD Card is unmounted, Screen off, CPU is under-clocked @ 104 MHz etc.) This mode can be compared with PC S3 mode. In this mode, with all radios off, my device loses max. 3% battery per day.
In screen-off mode, all the hardware except the screen is running (at full speed) and consuming the battery is a matter of hours.
My question is why would you need the screen-of mode? Unless you're using an application which really needs that, my advice is to use suspend if you don't want to charge your device more than once per day.

Thanks for the reply. I now confirmed that by actual testing too, and u were 100% right.
P.S. I wanna use screen off mainly b/c I wanna use the middle Enter button to turn on or off the phone. like a iphone style. So the best i can do is to map enter key to control backlight. While it can suspend the device, but it cannot wake the device from suspend since for Uni, i guess the middle Enter key and the navigations keys are not considered as "hardware keys" so i cannot map them to reactive the device.
Thats why I wanna know how to map the enter key as power switch as well.
hope someone knows the way, if there is any.

How to turn off magician?

how the hell do you turn off the device, if i press the power button once the screen goes completely black and i cannot tap anything but i can still recieve calls and if i press any of the buttons it comes alive. if i press and continue pressing for two seconds, the screen simply dims and i can still tap on the screen?
so how do you switch it off?
and if you reset how do you prevent it from loading the T-Mobile customization?
Also, mine has a dead pixel and i have just opened it can i take it back as faulty? it's only one dead pixel but it's really really annoying...does it count as a fault. i'm gonna try and take mine back tomorrow
A short press turns the unit off
A longer press will shut down the backlight, but leave the unit on

Well, when i do that the screen goes blank but i can still recieve calls and if i press any of the buttons it goes back on again!!!!!!!!!!!!
To totaly turn off the device you need to slide the battery lock button out and then back in. It is the only way I have found to totaly turn the device off.
To lock the keys go into "settings" then "system" and choose "button lock" then choose "Lock all buttons except power button".

oh, i see. i thought it was like the other phones, nokia SE etc.
thanks alot for all your replies
thank you
this is not a phone, this is a pdaphone, it works like a pda... if you want tu turn off the phone, you can use the flight mode.

I dont think it has anyhting to do with PDA. I have had 3 PDA's before. All of them had an "off" button that turned the thing off. Ditto for phones. So this is just Microsoft's strange decision. Dont make the guy feel back just because he is thinking logically - and they are not.
I've had quite a few PDAs over the years:- Casio E80? Psion 3, 3a, 3c, 5, 5mx, iPaq 3630, XDAI, XDAII, MDA Compact.
None of them have ever had an off button. They turn off the screen and may even slow the processor or put it in sleep mode. But they all kept their memory powered up and clock / alarms / appointments alive at all times.
This may change in the future as flash ram is now fast enough that you could actually run stuff from it so you could truly kill power (apart from clock and wakeup stuff) without emptying your memory.
My old Visor Edge, Palm Tungsten T, T2 and TE all had off buttons. I dont know of any electronic device where anyone should expect that the "off" botton doesn't turn it off.
If that button on Windows Mobile devices is a "sleep" button, then they should mark it with a "sleep" symbol, rather than the intl symbol for "power", which is what they have on there - and which is what confuses people.

So, if your Palm completely powered down when you pressed this magic "off" button, how come the alarms still worked? How come it woke up when you pressed any of the four application buttons or tapped the screen? How come your data was still kept in RAM?
More wisdom from the skagen...
My Nokia 6100 has an off button and it works. Doesn't stop my alarms from waking me up. So did my SE T610 before that
Everybody here has had a cell phone before. The all have "off" buttons that turn the device off. Only Microsoft, in its infinite stupidity, has decided to have a an "off" button that should in fact be labelled "sleep".
You are the one with no clue.
If you press the "off" button on your N 6100 or SE T610 you are right in that they would really be off. You can not receive a call, any alarms will not sound until you turn the phone on again and so on.
But this is not so for most PDA:s on the market.
Most PDA:s will go into some kind of sleep mode when you press the "off" button. And mostly it is not even a true sleep mode, a lot of processes are still running, and even network connections can be kept active. This is also the way most PDA users would want their PDA to work. Also, the way most PDA:s are built, a power down means resetting everything back to defaults and thereby loosing all of your data and third party applications. This could be cured by using non volatile RAM for all of the memory, but I guess there is probably a good reason why this is not normally done.
Actually, on most modern computers a short tap on the power button will put them in suspend mode and holding it for more than two seconds will turn them off. So the only thing that is really strange with the PDA is that a long press on the button will not even put it in sleep mode but only shut off power to the display. And as I actually don't know anyone that has ever used that worthless function I think they should probably replace it with a "real" sleep mode, where all of the hardware is actually shut off except for support voltage to keep the memory "alive".

On N 6100 ,and on all nokia phones, the clock alarm wake's up the phone... You then have a choice of whether to activate the phone or not...
Same with all the Siemens phones I owned ( 4 so far). When shutting off the phone, the clock and alarms keep working. The only thing that does not work, off course, is the radio so incoming calls are diverted to voice mail. But with the phone off, the alarms still wake me up!
It would indeed be a good idea if using the power button on any type of XDA would turn the device really off, using power only for keeping the clock working and the data stored...
If the alarms jeep working on your phone when in "off" mode it is not actually off but in a low power mode with the phone functions turned off. So what you are really asking for is that the power button should turn off the phone but keep the pda running. This seems quite useless to me. Exactly how often are you in such a hurry to turn off the phone?
Yes, the device is in sleep mode, but it is a very deep sleep indeed, since it uses close to zero power. When I put my Compact in sleep mode, running programs will not shut down but will stay running, the Today screen is still running and the same goes for the phone radio and GPRS. This means that the battery drains much quicker. So in order to save power, I have to turn off the radio (flight mode), kill running apps and then put the device to sleep with the power button. Seems like rather a hassle, doesn't it, compared to a normal phone? So I don't mean for the PDA to keep running ful operations, but rather to power down to a level where it only uses a little power to keep the storage working. And when waking up, I don't need to see the Today right away, a few seconds loading the screen like on a normal phone is worth the power save to me.

This guy is unbelievable. You were claiming that your Palm turned completely off when you hit the off button - not a cellphone, jerk.

Wrong - programs that can be _are_ suspended when you put the PDA into standby. Try it with MediaPlayer.
How do you know the Today screen is still running? Like you know the fridge light really stays on when you shut the door?
Wouldn't you be complaining more (because of the missed calls) if turning the PDA off to save the battery also killed the phone?
Most of us can get our heads round this - the Standby button on the side controls the PDA. The Flight mode controls the phone. Not exactly difficult, is it?

That's where you fall into sjkagen's trap, again. For the zillionth time, the Jam/Compact is not just a phone. It's primarily a PDA. That's why it costs so much more than a phone. And on a PDA, you need to be able to look up information instantly - not have to wait a minute for the darn thing to boot up.

Oh skagen, how ignorant you are. Seems you cannot understand pictures, let alone words.
The label on the Jam "off" button is a line through a broken circle, which is the IEC symbol for STANDBY, not POWER OFF. Just like on all other PDAs, and your TV remote control.
See
http://eetd.lbl.gov/Controls/overview/symbols1.pdf
Now look again at all your "phones" which completely shut down when you press the "power" button. What symbol do they have?
Seeing as you obviously have so much difficulty telling the difference between a cellphone and a Palm, a phone and a PocketPC, or a power switch from a standby button, here's another teaser for you.
1. How do cellphones manage to keep their memory when they are turned off or the battery is removed?
2. What is the difference between the memory in cellphone and that in most PDAs?
3. Why do most PDAs have Standby (Soft Off) and not Power (Hard Off) buttons?
Wow, seems like some people are getting really sensitive when I call the Magician a phone... Sorry if I insulted you guys, it is just that I compare it to a phone because I use it for that the most, but I do understand that it is actually much more than that!
I have no problems with the way the sleep button works, it is ok for me, I just wanted to say that there are other possibilities that could have been used to map the button to. Especially since some people would have liked the button to work more "phone wise". But since it is primarily a PDA, I see that this current application is the most logical thing for the button to do.
BTW you are totally right that most running apps are termintated when pushing the power button. Although WMP stays active in the running programs menu, the music is cut off. However, since the prog stays loaded, does this consume more power than shutting it down completey (e.g. with SPB Pocket Plus)?
I think the Today screen stays loaded BECAUSE IT IS RIGHT THERE AFTER WAKE UP, just as you say: it does not have to be booted first. BTW: I have a little window in my fridge door to check wether the light goes off .
And please guys, don't call each other jerks or ignorant just because someone's questions or remarks anoy you. Reply polite or don't reply at all!

Running programs in Standby Mode

Can any body tell me how to run progs. in standby mode. Especially programs like IM+ Messenger every time I press the power button I have to sign on again and thats not cool.I will give the program if needed. Thank you very much..
I don't think its possible, when you hit the power button, it puts it into a sleep state, meaning any running programs are paused, so the CPU isn't wasting your battery.
It sounds like you want a screen lock, for example slide2unlock, which you can set to lock and turn off your screen after a set time, or just bind it to a button, and hit that to lock/turn off your screen, It's what I use when listening to mp3s
Thats odd, on my standard rom I could go into sleep mode and go right back to what I was doing as far as IM and whatnot. When I flashed to nbd 8.2 last week Audio Manager would still run when I went into sleep mode (by pushing button), which was fine by me.

[idea] Shake to wake up?

Hi!
I would love to only shake my diamond and the backlight goes on.
For locking it i use s2u2. But the "Power on" button of the diamond is very small and not easy to find in the dark.
Is there an app which can do this?

Korbi
Actually, I just posted a request for something similar, only a bit cooler/geekier
http://forum.xda-developers.com/showthread.php?t=428994
not a good idea!
I don't think it will work so good as the last thing you want is to be walking and your phone getting unlocked!
good gadget though but don;t see it as practical.
I don't think it's possible. When device is in power off mode, all programs are halted and there is no way to check gsensor. Device will power on only on hardware events, like power button, GSM module, timer and etc.
i think major problem will be battery drain
checking gsensor constantly will decrese your batterylife extremly
And what about sliding the Enter Button ? Normally used to Zoom pictures. But it could be used also to lock/unlock. Faster then pressing the on/off Button i think.

Lock power button on TD2

Is there any way to lock the power button on the TD2?
I would like to keep the device suspended, with the screen off, even when the power button is hit.
This is to avoid that the screen of the device gets accidentally switched on when I carry it in the pocket of my jeans. This happens all the time, leading to battery drain.
I have tried TouchLockPro, it locks everything except the power button.
Any way to set this up?
Any application providing this feature?
If you lock it, how do you want to wake up the device?
I wouldn't mind finding a way to do something similar. Maybe not lock the button entirely, but make it so that you have to press the power button for a long time (say 3 secs), or press the power button and the hang up button and the same time.
no offence but if you did this wouldnt it unlock when you pull out the stylus?
and also you can change that go to start => settings => system/personal => keylock (also not sure if keylock will be installed as i dont have one, but you should be able to find it on here)
Then you can change the wake up to be any of the buttons, current setup or none.

No, this wont do what is needed. The Keylock simply stops someone from using the phone. It won't stop the screen from coming on accidental in you pocket.
You can 'lock' the phone from accidental use by pressing and holding the 'hang up' button, but again this has nothing to do with screen activation.
It is true that pulling out the stylus will both switch on and unlock the phone though, so disabling the power button may not be all bad. I still think it would be better to activate the screen via a single long button press, or some such.
Totally agree with swinster's comment and proposal.
- Lock the phone by pressing + holding "hang up" button (already implemented)
- Keep phone locked and screen off until
either stylus is pulled out
or power button and hang-up button are pressed at the same time
But disable screen-on when power button alone is pressed (like it is now).
- Anybody able to implement this proposal?
Meanwhile, how are you guys carring around your Topaz without the battery being emptied within a day (because of the described issue)?
This would be a great solution.
Mine switches on in my pocket all the time, they should have recessed the button, I thought about trying to remove it.

Its a bit of an overkil, but my laptop come with me most places.
Reminds me of the Morecambe and Wise sketch (??) where the battery was the size of a suitcase.
I think I need a car charger - which brings me to another grumble - why didn't they implement a standard mini USB interface?
Standard mini usb fits and charges.

Ooh, Ok. I thought they were different shapes. Will look into this.
[Edit - I have just read that it IS backward compatible with USB - the different shape is becasue the HTC connection supplies audio]
I'm guessing that any old Car Charger with mini USB will work then?

When you set EnableInputAtSuspend = 0, it will not unlock the power button at suspend. . It will then only awake via the Stylus. But I do not know if this setting also works on the Diamond2.
I am having some odd problems with mine if i press the power button to put it into standby. Sometimes when i press it it turns itself straight back on others it will come back on if i shake it (like the G Sensor is somehow linked to bringing it out of standby). Can you guys check this so i can confirm if i have a faulty unit please?
I think I read somewhere that someone had a similar problem - might be the stylus sensor thinking you have remove the stylus.

Thanks, sounds plausible, I'll call the supplier tomorrow.
I am sure that on my D810 I could set the lock on at zero seconds with no pin code. Then the keylock would come on every time I came out of standby but with no change of accidentally starting applications and making calls.
On my D2 the password is compulsory for keylock.
Any solution here? I don't want a pin code.
I power button fix would be even better to also save battery. The accidental turning on is a very annoying feature.

ye man,ive got this prob...the phone randomly unlocks bcoz the stylus sensor...im lookin for some application that turns the sensor off....havent found anythin yet...
This is still, by far, the most anoying "feature" of the TD2 phone. I can't believe that HTC did not have the forethought to think that people might actually put the phone in their pockets.
It should be a simple fix so that when the phone is off or in standby, the power button has to be press for say a second before the phone will come on, rather than just a single tap. They can do this to turn the phone off, so why not on?

[Q] Power button failure (alternative approaches)

Hi guys,
I'm experiencing some failures of power button of my HTC HD mini: it sometimes does not power on my phone and I have to press it several time before it reacts...
As I do not want to buy a new phone, I'm exploring some alternative approaches to power on my phone (power off is not a problem as I can use some application to power it off).
Approach 1
I'm using G-trigger which has a power on feature which may configured to any phone shake and which works even when the phone is in stand-by.
That works properly but the problem is that querying the G-sensor lead to a fast battery drain, hence this solution is actually an extreme solution that I may use only with some enhancements…
Approach 1a
I tried to work of G-trigger service in two ways:
a. By night: I configured a profile disabling the G-trigger service by night and re-enabling it in the morning
b. When in stand-by: I tried to disable the G-trigger service when in stand-by and re-enabling it when the screen turns on again. Anyway I didn’t figure out how to understand when the screen is on (I tried by mortscript here http://forum.xda-developers.com/showthread.php?t=1296958 but no success). Any idea??
Approach 2
I would try to use some of the volume button but I have no idea about: is there a way to trigger some program when the volume button is pressed when the phone is in stand-by
In conclusion, I don’t know how to proceed and I will appreciate any idea or suggestion.
Thanks in advance
