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 connection ever ON (is it possible?)

Is there a trick for mantain the wifi connection always on?
Because if i switch off the phone i loose my connection and the p3600 use the gprs connection for recieve the mail in background.
Thank you

That would kill your batteries very quickly...

Yes it would. When I'm at home I plug in my Trinity into the charger, which makes it stay on. I have the phone set to stay on while charging. This way I can have my wifi connected continuously and save on my 3G data usage.
I think when in standby the phone doesn't connect to data, it wakes itself up does the email check etc., then goes back into standby according to your power standby settings.

I've noticed that when using Wififofum, it still detects new wifi access points even when it's in standby.I don't know if it's really in standby, but at least the screen is off and i need to press Power button to see what it has found.

Wireless disconnects when screen turned off

Hey, tried to search about this but had no luck.
Whenever my blackstone gets the screen turned off by power saving it also disconnects from the Wi-Fi network currently connected to.. then it reconnects when I turn the screen back on again.
Is there a setting to avoid this? Pretty annoying when using msn messenger. Would like to be connected even with screen turned off.
Thanks for any input!

You can download HD Tweak it has an option to keep wifi connected when your phone sleeps, plus many other tweaks well worth the download
Just search for HD Tweak

Just keep in mind that wifi drains your battery pretty quick and with wifi constantly on it shouldn't last a day.

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.

Wireless on when standby

Was wondering if its possible to keep the wireless still turned on when the phone goes to standby. As in 3G is always on, thus always giving me new emails

Hmm #33 may be able to help you?

Easy....
Download Shap's Advanced Config Tool. There is an option to keep the Wifi on even when the phone goes on standby.
Once Advanced Config Tool installed, launch it, go to Menu/More settings/connections/Enable Wifi on Standby.
also I would recommand you to download a basic freeware named ScreenOff (by Applied PDA software), and use it to turn off the backlight without turning off the Wifi.

I've always having trouble to maintain the WiFi connection whether it's using battery or AC.
I've installed the Advanced Config Tool, the "Enable WiFi on Standby" indicated already enabled. Then I used the ScreenOff. After about 10 seconds, the WiFi connection was lost as I verified it by pinging the HD2 from a PC. It's plug into AC all the time.
However if leave the HD2 just "dim the screen", that seems to be the only way to maintain the WiFi. Obviously set it not to go into standby after 30mins (the default value).
Are you able to maintain the WiFi on HD2?

Yes. No problem here.

when you go into wifi advanced settings you can select power mode. when you set power mode in the medium setting, wifi keeps connected even in standby! and it also doesn't drain your battery while in standby. just try it. first select high power mode and turn phone in standby. wifi connection is lost. when you turn it back in, you will see wifi connecting.
with power in the middle setting, turning phone in standby keeps wifi alive, with very low power consumption. and when you turn phone back on, you will see that wifi is already connected.
i use wifi all the time when at home. my data connection is turned off. and still my push mails are recei ing through wifi!

Not that easy, I tried all power modes and in all occations it whent of after 1 minute (ping timeout). Weird that all roms behave so differently

Speaking of pinging your HD2... when your wifi is enabled and IDLE, what ping results do you get?
My HD2 acts very strange. when my wifi connectivity is on & IDLE (no data activity, device is not in standby mode), my ping results vary from 50ms in average to 200+ and sometimes I'm experiencing even higher spikes of 500ms+.
I have tried to change the wifi's adapter power scheme to "best performance", but it doesn't seem to change something.
However, as long as there is an activity, my ping replies from the HD2 seem to be fine (less than 15/10ms).

seems like some powersaving feature... when idle, why should the wifi chip work at top speed.. just like cpu scaling....

my power saving slider is in the middle and still when the screen goes off and I switch it back on the wifi is reconnecting.

Have you done the ping test from another PC/laptop on your network? Wait for about 1 minute after the screen is off and if you still can ping your HD2, I think it's probably your push mail somehow manage to maintain the wifi connection. I might try that if that's the case as I've tried absolutely everything else and so far abosolutely nothing can keep the wifi constantly on if the screen goes off.

i can still ping it after a few minutes... what you say about push mail and keeping wifi on makes sense... first thing i do when configuring my phone after fresh install is setting up my push mail... maybe that's why my wifi is always on.
You could set up a free gmail push account?

I'm not sure if my problem is related at all but my wifi only seems to connect to my router when it's diconnected from my PC. I'm sure before I upgraded to 1.48 ROM it stayed connected. Any idea guys?
oh, and I've only ever had it in the middle power saving mode and it looks like it does disconnect when it goes into standy.

I've set up gmail account as well nut as far as I know it's just IMAP or correct meif I'm wrong. if It's not push mail, it'll still kinda polling isn't it? what's your view?

Good news guys, I've finally managed to get the WiFi to stay on even after the screen is off. Yes the trick is the "push mail". I deleted my original gmail imap account and set up a Microsoft Push Mail based Gmail account. Then did the ping test and it's staying on for sure now. But I did notice that it'll have 1 packet drop occasionally.

wifi disconnecting in standby
my hd2 stayed connected to wifi in standby, then i applied a few tweaks and .cabs, i had a few little issues like the screen freexing and not refreshing so i did a hard reset, since then wifi wont stay connacted when the phone is on standby, it is confusing

Hi I found a solution. Just install this cab. No soft reset needed
