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...
http://www.pocketpcpassion.com/forum/showthread.php?s=&threadid=38598
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!!!
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?
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.
Hi,
I just got the focus couple days ago and have a question:
when you use the WIFI connection (at my house for example), does the phone turn off the 3G? does it use both? how does it work?
3G still remains on/connected providing your carrier and phone support 3G. when wifi is on and connected, it takes over 3G connection for data till you disconnect wifi again.

Yes and no.
There's a bit of a design flaw in WP7 that is catching many users by surprise.
What you're saying is correct when you're using the phone. WiFi takes precedence over 3G for data.
But, and this is the surprise, when the phone goes to sleep (mine's set to the maximum of 5 min), it turns the WiFi off, meaning 3G takes over.
Many people learn this the hard way, because they'll start some large download and leave the phone alone. At some point, the phone goes to sleep (the display turns off, basically), which turns off the WiFi, and now your download is switched to complete via 3G. Many people are wondering on the various forums why they leave their phone (say overnight) thinking it's on WiFi, and wake up to a surprise data usage number on 3G.
If your wireless router has a status screen to monitor live connections (I use DD-WRT, which does), you can see this behavior for yourself.
It gets better! If you're a "normal" user who plugs in your WP7 to charge up the battery overnight, you'll notice you can't turn the phone off. So, without taking any specific action, you have absolutely positively no choice but to burn 3G usage during the time period that the phone's plugged in, but not in actual use.
The workaround, if you're really tight on data usage, is to turn off your cell/3G manually, or switch to Airplane Mode, or stick your phone in a lead-lined box (okay, maybe not lead, but you get the point).
Brad.
I am frustrated with this too. I wish there was a simple toggle switch, application , that would simply turn one of them on and the other off without going into settings everytime.
This is very interesting (and a little worrying). How can I check my data usage from the phone?
Data usage
Dial *3282# and hit call
A text will come in with usage.
I make a habit of turning 3G off unless I need it, just to avoid 3G being used over WiFi or apps auto updating.

correction:: When you plug in your phone for charging the wifi stays ON even during standby, so 3G data is not used during this period.
@pigue
"Dial *3282# and hit call

That didn't work for me... I'm in Canada on Rogers. Is the number different up north?
im having problem with my 3g data.brought in my phone to my service provider.they couldnt fix my data because they were looking for the proxy and port.but they can only the apn settings.pls need help.im paying for data and im not able to use it.

Thanks for that clarification. I spent a bit of time yesterday monitoring my WiFi connections and it appears as though you're quite correct, WiFi does stay on the phone's when plugged in. That's a tolerable workaround.
Pity none of this is actually documented, and we're all forced to figure this out for ourselves.

I read about this in the documentation for the wifi sync somewhere. Can't remember if was M$ documentation, though.
This tip is one that seems counter-intuitive, but you can save a lot of wear and tear on your Android phone's battery if you tell it to keep the Wifi radio turned on and connected while the phone is sleeping. Your phone needs a lot of juice to keep pinging those cell towers, and even more to transmit data to and from them. Wifi radios use much less power because of their design, and they don't have to keep searching for a better access point. It's the way cellular data communication was designed, and it's a necessary evil.
But what if you're spending all day (or all evening) in one place, connected to Wifi? If you tell your phone to shut off Wifi when idle, it bounces back to cellular data (be it 2G, 3G, or 4G) and starts sucking down the electrons again when the screen shuts off. That's no good, and easy to fix:
Open the advanced Wifi settings by pressing the menu button, then Settings, Wireless & networks, Wi-Fi settings, and tapping the menu button again. You'll have a choice to either Scan, or go Advanced -- go Advanced.
Tap the Wi-Fi sleep policy entry, and you'll get a pop up dialog with the 3 choices. Choose Never.
Now even when your phone goes into standby mode, you'll stay connected to Wifi and be able to get mail and messages without turning the cell radio back on and trouncing your battery life. And for the times when you're not in an area with a Wifi connection, just shut Wifi off, either through the menu or with a handy toggle widget. Your battery will thank you for it.
#Its only for those beginners who dont know about this setting...
dont you mean tick always, as if you tick never itll go back to using your dataplan instead of the wifi
Re: [Guide] Save Battery By Keeping Wi-fi Alive
I use to believe this but for some reason on my sgs3 wifi drains more battery I get more juice with wifi off.
Results may very due to your services supporting fast dormancy, etc.

You need to choose "Always", not "Never". If you choose "never", then it disconnect wifi as soon as display is turned off.

If you're moving out of wifi range, or in and out of wifi range, turning wifi off will use less power as associating with an AP has a high energy cost. But as the original poster says, if you're going to be sitting in one place all day e.g. at home or at the office where your phone will always be connected to an AP, leaving wifi on and always connected will use less power than 3G.
More details here:
http://people.cs.umass.edu/~arun/papers/TailEnder.pdf
I suppose it's not that surprising. I'm sure many of us, after buying a new phone, have left the old one sitting around at home without a SIM card but connected to wifi, still polling emails and everything. The battery lasts ages!
Re: [Guide] Save Battery By Keeping Wi-fi Alive
This might be irrelevant, but i red an article her in xda about modern mobiles battery long time ago.the article said that when wifi on or off has no significance effect on battery life (regardless of other sitting like carrier signal .....etc)

Apparently FD doesn't affect battery life that much (See here, second post). I get better battery life on wifi and I think that's still the case for the majority of people if they are within a wifi area.
I tried and with option "always" I have more battery drain, cca. 2%/h in idle/screen off/overnight. With old setup when Wi-Fi is off in case screen goes off, I have cca. 1.6%/h. So, it doesn't work for me. Thanks anyway.
What ive found is to turn your 3g to 2g, that will save a LOT of battery. I use 3g if im out and about where theres no wifi, if im at work i dont use my phone often so switch 3g to 2g. It still brings my notifications in time. And at night switch to 2g as well.

But that's a no brainer! Of course battery life will last a lot longer on 2G! Your battery life will also last a lot longer if you have no data connectivity. The discussion here is between data and wifi.
