Anyone here who is able to use WiFi correctly while set to anything but "best performance" power mode (Advanced settings)?
In my case, after switching to the "middle" power-save mode, the ping raises to 300-2000ms and Internet connection slows down and stops working at all after while - although the signal strenght does not change and the indicator still shows cca 75%. No matter that the device is only 1m far from the router.
I'd love this to be working properly as it is reported to improve the battery life with Wi-Fi, backlight and constant pinging on from 3 to more than 11 hours. I'm curious if this works for some of you (?).
Same issue here.

2hours 40mins
that was how long the M5000 survived.
Conditions of test:
streaming London's Heart 106.2 over WiFi, access point in the same room, wireless settings at max power save
the phone was on, and the display was at max brightness
out of the time, 18 mins was spent talking over UMTS on speakerphone under max brightness
during the test, some activity was also done...tapping, opening menus...etc
observations: during the test, all connectivity failed at one point, (usual bug with this thing.....loses wifi, cant connect to mobile network unless flight mode is cycled or phone is reset)
if im not mistaken this happened about 40 mins into the test
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
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

Sorry, this does not work.. Goes away after a soft reset
I seam to loose all internet access as soon as I have my battery under 33%, it still connects to the network but I only get timeout connections. Is there a low battery setting that I am missing that limits the wi-fi power?
^try to remove power saving, as far as I remember, I used mine with15% battery left, no problems
Hi,
I thought that I could use Tasker (https://play.google.com/store/apps/...EsIm5ldC5kaW5nbGlzY2guYW5kcm9pZC50YXNrZXJtIl0.) to save battery life. So, what I did was to prepare the following profiles:
a) Disable autosync, enable it to 3 minutes every 30 minutes. Sync only between 6:30 and 23:05.
b) Enable autosync while on AC power, disable when not.
c) Disable wifi, enable it for 15 seconds every 15 minutes so the system would have time to connect to a known wifi if available. Then disable wifi unless its already connected.
d) When a wifi connection starts, do nothing. When it gets disconnected (like when I leave home), disable wifi.
I only use EDGE. I only sync gmail, contacts and calendar.
Before this, I had autosync and wifi on all the time so I believed this setting should conserve battery. Everything works, Tasker app itself is not draining much from the battery (according to Betterbatterystats its really negligible) but still, I have a considerably higher energy loss than with default setting.
Do you know whats the reason for this? Is is caused by the wifi enabling and disabling - taking more power? Is it caused by the fact all sync gets done at the same time? Or why is that?
Im generally happy with the Nexus S battery life but this outcome makes me curious ...
EDIT: My advanced wifi system setting always was "never disable wifi when screen is off". Also, for the purpose of this test, I disabled wifi AP on my router to check just for the outcome of the wifi search.
Check out your Awake time (can find this in BetterBatteryStats), you'll probably notice the phone stays awake for longer than it would normally. Normally the phone would go into a practically permanent "sleep" state, powering nothing but your radio, when the screen is off and doing nothing. It would just wake up every X minutes to autosync or for other alarms (exchange sync, etc) and then go back to sleep. I wouldn't be surprised if it is solely the wifi option.
Depending on the advanced setting in the wifi options, it keeps the connection indefinitely or drops it after a certain amount of time, i think around 15mins - 30 mins. This may need to be changed to fit the circumstances.
Overall though, benefiting from the use of Tasker or similar program for battery life purposes doesn't gain much over what android already does (albeit still with alot of room for improvement).
Well, I should've mentioned this: My advanced wifi system setting always was "never disable wifi when screen is off". So thats not possible reason.
Also, for the purpose of this test, I disabled wifi AP on my router to check just for the outcome of the wifi search.
I basically believed that before, the phone had wifi on and checked around every now and then. And with the new setting, it would check less often, therefore saving battery.
Awake time is about 40 minutes in 7 hours sleep.
EDIT: Maybe it would help to adjust the times better.
