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?

How do you switch it off ? I have set the thing to switch off automatically after 2 minutes, but its still on after 3 hours and the battery has dropped from 99% to 40%. I had the bluetooth on and everything else switched off.
It is one week old.
Is the battery life normal ?
I'm sure it didn't switch off.
thanks
I have a jasjar. First thing i did, i uninstalled antivirus and skype. I keep it all day on with bluetooth active, and everything off at night. Based on calls and activities i put it on charge every 3 or 4 days.
I have set my MDA Pro to turn off after 3 minutes, and it does indeed turn off. If I don't touch it (turn it back on), the device can go all day with negligible battery usage (a few %).
Bluetooth is off. WiFi is on. 'Incoming beams' are off.
I sync by cable, so the device is powered while syncing. If you sync via bluetooth, then perhaps activesync is keeping the device awake even though it is not powered.
If you turn it off manually (power button on edge near SD card slot), does it turn itself back on? Mine does that when activesync is running and connected. Otherwise it is happy to stay off until I get a call or some reminder.
go to the phone options and change from Auto band select to GSM. Using 3G sucks battery like a mofo
my main issue is that it should have turned itself off
1) in the comms menu, only bluetooth was on
phone was off
wireless was off
beam set to off as well
From 98% charge to 40% in 3 hours, when I hadn't used it at all.
I am sure that is not usual.
So gsm/3g/gprs shouldn't have any bearing on the batt life, as it was set to off ....
was bluetooth actively doing anything during this time or just on and sitting there?
Firestomer, the following eat batteries:
- PIE running in the background
- Camera app running in the background (can be activated when you shut the camshell as it is easy to hit the camera switch on the front)
- UMTS (which is not a problem for as your radio is off)
hi joe
BT wasn't doing anything - I closed the clamshell and left it expecting it to switch off, but I guess it didn't since it chewed through nearly 60% power in 3 hours.
Also, what is the technique for switching it off ? I have pressed the power button to the left of the SD slot, all it does is switch the backlight off. I have held it for 0.5 seconds, 1, 5, 10 ....
I am loosing patience with the thing - wifi isn't working for me and TomTom5 keeps forgetting it has a GPS connection ...
btw what is PIE ??
firestomer
PIE = pocket IE
Two clicks of the off switch will turn the device off
On my device BT only uses about 10/15% of battery over a 12 hr period
Are you talking about svitching the device entirely off? i dont think that can be done...exept if you take the battery out and put it back in and dont turn it back on
yes as close to off as possible when I am as sleep etc, but it guess it needs to keep the clock and alarm and keypressed detect powered ....
Will Wifi drain my battery even when in sleep mode ?
I charged my phone last night as I always do right up to 100%. Left it in sleep mode and went to bed.
Received a call this morning and when the phone switched on noticed my battery was on 26% and it was trying to connect to wifi.
Is wifi similar to bluetooth in that I believe bluetooth will still be active and receiving in sleep mode and will so drain the battery ? I could have sworn I have left wifi on before in sleep mode and it didnt drain the battery, but maybe I am wrong.
So will wifi in sleep drain my battery to that extent ie from 100% to 26% from about 10.30 last night to 10am this morning ?
The wierd thing is I was playing with it all day yesterday and the battery only got to 39% or something.
Is something wrong ?
yes, leaving your wifi on will cause battery drain. If there's any traffic, this gets worse
Also activesync may have been running and trying to connect every 10 minutes or so. The activesync problem has been mentioned in another thread.
Just hope its just battery drain and not a fault.
Yes, I second the observation... 2 hours powered off drains 40% battery power...
That sucks, the blueangel didn't do that. It automatically turned wireless off on shutdown and turned it on again on wakeup.
Now I'll have to get used to doing that manually... :?
If you still have the BA, or if somebody else could check, look for this key in the registry:
HKLM\System\CurrentontrolSet\Control\Power\State\Suspend
There will be various values there. Default = 3, means state D3, which is the suspend state.
If there are any other values there, please note the value name, and the value of it.
If there aren't, check whether there are any subkeys.
For example, the Qtek 9100 has subkey {98C5250D-C29A-4985-AE5F-ADE5367E5006} which, if you look under HKLM\System\CurrentontrolSet\Control\Power\State\Interfaces\, you'll see is "Power-manageable NDIS miniports". Its default value is 4 for state D4, which is the -off- state.
Basically, I suspect, or rather expect, that the BA will have another value or subkey there which will refer to the wireless connection, and set its state to 4 as well. If that's not the case, then it's being handled more directly by whatever power manager adjustments they have made - rather than letting Windows CE's power management handle it as above.

The daft thing is when you switch your device back on, you arnt connected to the wireless network and it has to find a signal again. So its like its keeping the wifi switched on but for no reason whatsoever !
What would be cool is if on putting the device into sleep mode it would automatically put the wifi into low power mode so you could leave it on without it whacking your battery and you could possibly receive msn alerts.
That was sort of what the BA did.. :?
I still have it but with a broken screen
So unfortunately can't check, maybe someone else?
I think I've found the way to deactivate wifi again when the manager doesn't want to. Tap on the OS's connectivity icon at the top of the screen. It may say Enable wifi or disable wifi. If it says activate, tap once to activate and once again to deactivate. If it says deactivate just tap once. Then go into the wireless manager again, it should now be off. Works for mine at least
My 8125 is suddenly running out of batteries very fast. I suspect this is because of some activity running - if I turn the unit off, and leave it on my desk overnight, it is exhausted by morning (I, on the other hand, am exhausted by morning only if I am turned on. Sorry.)
I have checked for:
alarms and notifcations that are set to go off - there seem to be none
mail and other internet access items - there seem to be none
programs (like SPB Weather) updating themselves too frequently - there seem to be none
My energy settings are normal; sleep in one minute, backlight down, etc.
Is there anything I'm missing? Any suggestions?
wifi, bluetooth. make sure they are turned off.
That's exactly, WiFi and BT even when active in standby really drain the battery quickly.
thanks so much, but.... Wifi and Bluetooth are off - I never turn Wifi on, and I almost always keep Bluetooth off (though I wish there was a way to quickly - or even automatically - turn it on or off, ie, whenever I use it in phone mode, BT would turn on, and when I hang up, it turns off.)
any other thoughts?
Battery Gone Bad
Hey I think your battery is gone bad.
BT Off
Wifi Off
Backlight Down
Sounds to me battery is ready to go to the recycle bin lol
Also check your MSN Msnger Is not onn all the time.
Bernie
maybe it is the battery. the unit is less than a month old, but I just bought a spare battery. I'll compare run-down times on both.
a related question: why would WiFi and Bluetooth consume battery power if the unit is asleep?
-thanks-
I started getting horrible life out of my battery as of last month, but then I upgraded the ROM on it and have been getting FANTASTIC battery life. Better than when I first got the device.
which Rom did you upgrade to?
Summter <sp?> 2.3 for Cingular

Did you solve your battery problme?
when i am out in the country, where i might rarely get a signal, my battery drains real fast, prob to do with the constant searching for a signal to connect to.
I came upon this thread after my 8125 began having problems with the battery life last week. I'm wondering what kind of battery life people are getting and which settings they have.
For instance, before last week, I was getting little battery drainage during a 9 hour shift at work. Then this week, I was getting close to 55% battery drainage over the same duration. Just a few moments ago, I checked my battery settings and I found out that for some reason, my phone wasn't shut off after 2 minutes of idle time as it was originally set at. Okay, I'll test my battery usage tomorrow at work, but I suspect that was the problem.
Then it got me wondering how long other people have for battery life. With Bluetooth on, wifi off, lowest brightness setting and my auto shut off set at 2 minutes, I was able to last an entire 9 hour shift on standby with only about 4 - 5% drop in battery life. Hopefully, that is what I'll have tomorrow when I test it again with the auto shut off setting in place. What are others getting for battery life (please specify your settings).
I've forgotten to charge my phone at night before, and have had no problems making it through the second day of usage, though I'll usually get a low battery warning.
I keep Bluetooth and data connection on constantly. Don't use Wi-Fi unless I need something really quickly. Backlight is at the lowest active setting. I would say I use it moderately throughout the day. I use it to take important notes and make reminders for myself, along with surfing the internet without worry.
hi
Please check out activesync which drains the max battery..
make sure that activesync is not running in backround. once after disconnecting your mini-usb cable connectivity from PC please check for the activesync status.. if running turn it off.

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
http://forum.xda-developers.com/showthread.php?t=582108
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.
okay--i've been struggling with this all week and I can't figure out what is doing this. It might be bluetooth but it could be something else.
As I understand it Wifi should turn off when I put the phone in standby. For the first half of today that was the case. then mysteriously, it stopped turning off and guess what, my battery usage disappeared.
I have checked my BsB tweak settings, it is not set to have wifi on in standby. I have checked my wireless connections to disconnect after 30 seconds. Although that probably only works if i am away from a wifi signal all together.
so what else do i need to do to switch it back to default--I don't want wifi on when it's on standby. At the least, i want to be able to toggle it like it's supposed to.
thanks for the help. Once i get this figured out I am pretty confident my battery usage will be good.
