Extremely Bad Battery Life on the XDAII when the PDA is off

Hello,
I was wondering if anyone else is having the same problems.
When I go to bed I turn the PDA off. The phone is still on.
When I wake about 7 hours later I find the battery is at 60%.
What's the deal? I thought it was supposed to have 150 hour standby life.
I do find something else quite weird. When I turn the PDA off the screen turns off and it all seems fine. I have the button lock turned on so no other buttons will work. After a couple of minutes, if I move the volume slider up or down the PDA will beep. Then if I press any of the buttons such as "Record" "Camera" and "Calander" Nothign seems to happen.
But when I turn the PDA on the "Recoard" "Camera" and "Calander" applications will load.
It is kinda of like it isn't turning off the PDA at all.
Anyone know what I'm doing wrong or how to fix it?
Thanks

if grps is only and bluetooth is on and maybe messenger and or icq is on it drain the batt

GPRS and Bluetooth are both on but GPRS is not connected. And Bluetooth is not connecting to anything.
I don't use messanger.
Would that still be draining the battery that much?

Cyeoh,
Unfortunately, I know exactly what you are going through. Your phone is entering a mode called 'resuming', it’s a low power state that does not turn on the display, etc, but will respond to hardkeys, volume slider, etc......
I'm guessing your XDA2 goes into 'resume' while trying to find a GSM signal, (are you in a weak area). This is my problem, you can read about it here...

As a test, you should turn off the phone, (flight mode) for one night and compare the battery in the morning, (I'm willing to bet is almost the same as when you left it). Alternately install an app that monitors cpu usage, (like the one in the above link), and you probably will see a similar pattern to mine.
The registry solution does help, but causes problems with Bluetooth, (at least it did on my device, nothing a soft reset didn’t fix, but it was VERY annoying)….
If it is your GSM phone, you might want to try using another GSM SIM card from another provider, (maybe a friends) and see if you get better results. When I switched to a better provider I got an increase of 10% on the battery, (not great but something!)

Thank You very much.
That does answer a lot. I do have very bad reception at home. I guess this may mean I need to leave it charging over night. However I do find the XDA does charge very quickly which mean in the time it takes me to get ready for work it is back up to 93%.
I will put it into Flight mode tonight to see what happens.
It's still a little bit ****ty and it seems to be because of software. Hopefully they will fix it in the next ROM update.
Thanks
Cam

How did you go with your test last night cyeoh, did your battery last a little longer?
I'm intrested to know as when I charge my battery over night in the morning its still is not on 100% untill I do a soft reset or disable and enable flight mode then it pops up to 100% and stops charging... yet a nother feature of some software I've installed or the ROM version at the moment!!!

Missing icons from bottom of screen

I seem to have lost the ability to rotate the screen and also to switch input modes (keyboard/pen) on my XDA IIi... The respective icons are both missing.... Does anyone have any ideas?
Oh, on a related note, the device seems to guzzle power - I get about 12hrs from a fresh battery (and I've tried three). Any suggestions?

On the power front, I presume you're on an XDA2i? Is your turbo mode on? Is Bluetooth on constantly or wi-fi? What are your power save settings? You'll need to be more specific.
Cheers

Turbo mode is off. Power save settings are default, or more conservative (lower brightness on battery, for example). Yes, it's a 2i.

I've recently rebuilt my 2i (with all the same software as before) yet this time it also seems to guzzle the juice. Turbo mode is off, and I can't think of anything that could be causing it as last night the wireless was off and yet when I woke up it was 23% battery!!

WiFi kills battery when Universal is switched off?

Hi there,
With my BlueAngel I could leave the WiFi on all night as when the phone was switched off it did not eat up the battery - when the phone was switched on it would spend a couple of seconds reconnecting to the wireless point.
The Universal seems to behave in the same way, yet it eats up all the battery overnight even when I have switched the phone off and it is not connected to the WiFi access point.
Is there some setting or registry key I can alter to fix this?
Cheers,
Quilty

@Qulity, if you don't close PIE I have found the battery can be drained. I assume overnight you are using Flight Mode.

Are you closing the flip and presuming that the device gets turned off or have you actually set your device to turn off after a fixed period of inactivity in the power settings?
If it is the former, then the device actually does not turn off if there is any activity in the background like active GPRS or WiFi etc. A simple solution to this would be to press the hard-ware on/off button once you are done irrespective of whether wfi is active or not in the background.
Try it out and post your results here.

My device is set to turn off after 2 mins on battery power, but I made a special point of turning it off with the hardware button before testing last night. As I said before my BlueAngel never behaved like this.

my jasjar was turned off yesterday, and every 5min i heard sound for new wifi network!! same problem, i solved it with turnig wifi off!! any other solutions?

Wifi wont turn off in sleep mode

Hi Guys,
I got my HD2 today and i have to say i am impressed!
I only have one problem which i am not able to resolve.
When i turn on WiFi, it wont turn off during sleep mode (when i turn off the screen). i need to manually turn it on or off. this is how it came out of the box.
I wonder if other HD2 users are having the same problem / found a solution?
I tried advanced config tool, and i unchecked the "wifi during sleepmode" setting, but after each reboot the settings just come back.
Any help would be appreciated.

Hi mate, you should look this

I thought that guy just want to keep WIFI on but you did.

thanks man but it does not help me with my problem. I cant seem to be able to get WiFi to auto turn off when in standby. the reg tweak will work until you reboot the device. after reboot the WiFi again won't turn off when in sleep mode unless I manually turn it off.

Bump.
Can any other HD2 owner please confirm if this is happening on his device too?

Same problem.
HDtweak and AdvanConfig does not work. After soft reset, wifi-on-standby is back ON (checked).
Been trying to find a Auto-Disconnect for GPRS(HSDPA) but the above 2 apps does not work too.

have you tried to change wifi power settings to high? I think it does work then. I guess the medium setting is something special...it keeps the wifi connection alive in standby, but also doesn't consume much power. I have an exchange connection active, so i always need an internet connection. The moment i turn on wifi at home, it stays on, even in standby, and my data connection over 3G disconnects. My exchange still works perfectly...and no huge power drain! My wifi power setting is on the medium setting...

Yes, I can confirm I'm encountering this issue too - on my HD2.
Strange, 'cos I wasn't at first, I'm sure - I remember the wi-fi notification icon flashing when resuming from sleep.
glenner05, can you confirm that you can get wi-fi to sleep please?

Hmm.. thought it might be connected to the htckeepwifionwhenunattended registry value but mine's set already to 0.
There're others trying to do the opposite!

Anyone else found a solution?

I think HTC made this by design. If you turn GPRS data off and leave Wifi on while in standby you will be surprised how low the power utilization is.
I tested and with GPRS data off and Wifi ON, in standby you lose about 2% battery per hour...that's nothing.
It seems that on the HD2 the Wifi power consumption is really optimized so no real need to turn

Mine is on default Wi-Fi settings and when it goes into standby, wi-fi goes off.

Yeah goes of in sleep mode, if you get wifi toggle, you can choose to keep it on or turn it off when you like .
Shame the grps is still a problem....

pgamble and jrvenge: you really mean wifi switches off on the device when it goes to sleep? Ie. you see it disconnect from your router or something?
jrvenge: what did you mean by, "if you get wifi toggle"?
clubtech: when I read your post I agreed with you, maybe. I can't now be certain I remembered correctly that I'd seen wifi reconnect. And yes, the power consumption does seem low

There is a cab floating about here that enables you to force the wifi on always or turn it off.
If you forc on it stays on, if you turn of it goes off.
Return to normal and the hd2 does its power saving thing, so im all sorted there, just need a timeout on the gprs now.
If you cant find it let me know. It works a treat.

can youplease post the cab ? I have been looking for something like this .

Sure pm me your mail and i will send it

GPRS Disconnecting software here fella's, tested and working on my HD2 100%
May also turn off wifi but i've not loked yet, just about to leave for work so will check later!! lol

Ok just tried and it does not do what we want with WiFi

Yes ... if device goes to standby, when it comes out .. you see wi-fi searching to connect again ... so it definitely disconnects and the reconnects when it comes on again.
Paul.

Yup your right!
If it's in balanced or best battery mode then it turns off in standby and reconnects/searches again when you press a button to bring up the lock screen.

[Q] Bluetooth GPS Disconnecting when screens off

Running a Nook Color with CM7.1 stable. Kind of an odd issue here, I have two different Bluetooth GPS devices, and when they are paired to the Nook and I turn my screen off and then back on, it loses the connection. The only way to reconnect the devices is to restart the Nook, as it fails to connect after the screen is brought back up. I have found that if I have the Nook plugged in for power, this issue does not happen. I have tried multiple GPS apps, reflashed CM7.1 multiple times, but still have no success unless I have the Nook plugged in, or I just ensure the screen doesnt go to sleep.
I really need this to work, as I'm using this as a pilot, and I can't have the screen on the entire flight as it will drain the battery quickly. I swore it used to work before, but I know I had issues with it, and maybe now realize what was causing those issues. On a side note, my friend has also tested everything I have done, but his works consistently and reliably regardless if he leaves the screen off, or turns it on and off repetitively. Hopefully someone may have an idea!!
Thanks in advance.

So noone has any thoughts or ideas at all?

Well seeing as it doesn't happen when your plugged in that would make me think that it has something to do with the fact that WiFi turns off when the screen is turned off. The Bluetooth and WiFi are on the same module i do believe. The default setting for WiFi is to stay on all the time while plugged in and turn off when the screen is turned off while on battery.
My suggestion would be to turn the WiFi to stay on all the time and see if that changes anything. Go to WiFi settings --> menu --> advanced --> WiFi sleep policy -->never. That would be my suggestion, hope that works for ya!

That's what I was thinking too. It seems that when NC goes into deep sleep Bluetooth will lose connection. By removing deep sleep you should be able to stay connected, although your battery will drain faster than with deep sleep on, it should have a better life with screen off than on.

Well I appreciate both of your responses. However, I should have mentioned that I do already have Wi-Fi set to always stay on/never sleep. Any other suggestions?
