Any script i can run or modification to permanently disable Wifi power saving mode at present?
Wifi works fine at home, but at work with about a million other access points around it doesnt seem to maintain a stable connection unless I disable power saving. I would rather set it permanantly if anyone knows a way.
Thanks
Matt
Just to follow up on my own thread, i dont believe there is a way however disabling Wi-Fi PSM most definitely reduces battery life.

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.
Hey guys,
i have a weird problem. I'm depending on the wifi from my neighbour atm (he gave me the key - everything legit ) and i tether it via my Desire HD to my PC. But there's this strange behaviour i discovered: When the Display is turned on, i get a ping of about 30ms. When the Display turns of it rises to about 600-800ms.
I have a rooted DHD with Cyanogenmod 7.0.2.
I tried to fix the CPU speed to 1GHz - Performance with SetCPU but it didn't help and i set the wifi connection not to go in standby whilst the display is off.
Does anyone have an idea about this?
Jack
It seems that some of the DHD's Hardware does go into standby although you disabled a few options.
Maybe this could be solved with another kernel, but i guess you would have a higher battery drain then, even without tethering.
Why don't you just leave the screen on? Start its desktop clock and it'll be a nice gadget on your desk

Hi Jack,
I have a base rom or whatever it is called. I have the same problems. I tether using my 3G connection. When the device display is turned off, the tethering has speed issue, while it is turned on, tethering works fine. I haven't found a solution yet. i just keep my display on, since its connected to pc, it will be in charging state.
Regards,
HD
Hey guys,
thanks for your replys, the best idea would pobably be (for now) to leave the phone in "desktop-clock-mode".
Thanks for your Help
Not a fix but a work-around...
Since I guessing the phone is connected to the PC, could you not set the phone to not sleep when charging (menu -> settings -> Applications -> Development -> Tick "Stay Awake")? That way the screen will stay on when ever it's charging be it mains or via USB
(EDIT: Appreciate you get this using desktop clock but this saves having to mess about every time.)
Change your wifi power saving options. The behavior you get is default, to save battery life. It's under the advanced settings in the Wifi settings, IIRC.

If you're talking about the sleep policy the OP says he's done that already.
Changing the sleep polici doesn't do it
Thanks for the hint with the display staying on while charging!
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.
wifi nexus 7. turn on airplane mode. manually turn wifi back on. what stays off, anything? GPS? Does airplane mode have any use or advantage on a wifi only device. Any battery use changes or background processes that stop? Thanks for any responses

Probably no bluetooth, either. I know it turned it off on my old work blackberry because it was on the same screen and you could see it turn off.
It should turn off EVERYTHING wireless. That includes, to my knowledge, WiFi, GPS, NFC, and Bluetooth.
It should help with battery life - although probably very slightly. GPS/NFC/Bluetooth truthfully have very little effect on battery life as is, and WiFi isn't that big of a hog. But it certainly could help to eek out an extra few percentage points if you *really* needed it.
We just switched internet providers at the beginning of the month, Wifi was going in and out with our previous internet provider A LOT. Wifi and internet has been much better lately. But today I noticed Wifi went in and out when I go to unlock my screen it's off and once I unlock my screen it comes back on quickly. Is this because I have power saving mode on? I did a FDR a few days ago and it just started doing it tonight. It's only on my phone. Is there a setting I can find that will fix this?
Yes it's because of power save mode causes it to turn off Wi-Fi to save power.
I don't know of any fix except to turn off power save mode.
