First and foremost let me say that I love this phone. But I am having an issue with serious battery drain that's occurring when I have WiFi on. I need to use WiFi Calling in my house,and it worked flawlessly on my previous mytouch 4g, running under the same conditions. In fact, my wife now has that phone and it works great, we actually manage to save a ton of battery with wifi calling turned on.
So when I got the Sensation I hoped for more of the same, great battery life when at home due to wifi calling. However, that is not the case, when I have wifi on, with or without wifi calling enabled, my battery drains at a rate of about +-10% an hour! And thats with out even touching it! Without wifi on, 2-4% per hour battery drain.
Speeds when I do things over wifi are blazing fast, and the signal is full bars, so I know the phone is not searching for the wifi. With wifi, and minimal use, I max out at 5-6 hours! Not sure what to do, as not using wifi is really not an option.
One other thing, coming from the mytouch 4g, a highly underrated phone imo, I do see some lag that wasnt present in the "lesser" phone. In particular, the USA Today app, for example, on the Mytouch scrolling was smooth as butter, not so much on the sensation, I also see it in the Android market when I look at my apps, same app list on both phones, mytouch scroll is smooth as can be, Sensation is very jittery.
Maybe someone has some thoughts, or is having similar issues, cause I am so jealous of all the "OMG my battery lasted 6 months" posts!
Thanks in advance!
Because the phone comes stock with the WiFi sleep policy set to never. In my opinion that's a stupid decision on HTC's part. Easy fix though. Go into Wireless settings and clock on WiFi settings. Then click the menu key and click advanced. You will see the WiFi sleep policy menu. Just change it to "Never When Plugged in" or after 15 minutes. If you change it to Never when plugged in then the WiFi will go into sleep mode when ever you turn your display off.
Ive had it set to the 15 minute setting, but I thought that the wifi calling would block wifi from sleeping. Once when looking at the battery screen, I zoomed either on wifi or wifi calling, and it said something to that effect.

Sorry, I forgot you said you use WiFI calling. That might have something to do with it. I always keep mine of so it doesn't matter if my WiFi sleeps right away.
Wifi can't sleep!
I don't know if i should start a new thread but this was the closest to my problem I could find.
Basically I'm having the same WiFi battery drain issues, and I tried to do the usual Wifi Sleep 'after 15 mins' or 'Never When Plugged in' options in the advanced menu but it always reverts to just 'Never' after a few minutes.
On my power graph it shows that I have had continuous wifi on despite changing the settings. So its not just the option returning to default when i open the menu either.
I'm really confused here, is there something forcing my wifi to be on all the time?
Any help is much appreciated.
Make sure wi-fi best performance is not checked. That will drain battery faster also

In the wifi sleep policy, it is possible to set wifi to sleep after screen off. However wifi does not sleep immediately but 15 minutes after screen off. I would like wifi to sleep earlier, say 5 minutes after screen off.
I searched around and found an app capable of doing this. But it is for samsung phones and doesn't work for defy. Does anyone know if and how it can be set manually?
Juicedefender. That is the exact app to use.
I tried Juice Defender. There are options to disable wifi based on connection existence, preset time, data flow etc, but there is no option to set the how long after screen off wifi would sleep.
Here you go, this should do what you want: http://forum.xda-developers.com/showthread.php?t=774507

Hmm I actually set my wifi to never turn off automatically. For instance yesterday I made a phonecall with Skype. My mobile connection is too slow for that so I switched the wifi on. During the phonecall I had the screen turned off but of course the wifi needed to stay on.
I have a widgetsoid widget on my homescreen to enable/disable the wifi. Don't like it when things go automatic and it's just as easy when you need wifi only once in a while.

Since i changed my ROM, my wifi actually goes to sleep after 15 minutes and I don't want it to turn off.
How do you set your wifi to never turn off automatically?

Thanks! Unfortunately moto doesn't have the settings.db file. I tried putting the mentioned key "wifi_idle_ms" in several other files but no effect.
Edit:
Stupid me. I find the location of settings.db and it works perfectly now
For information, the location of defy's settings.db is:

If you intend to save battery, maybe you should consider leave "wireless policy" to "never sleep".
It might sound senseless but there are a lot of people reporting substantial battery savings with this, including me, i noticed at least +20 hours in battery life only with this little thing. Charts drawn with Battery Monitor showed the same consumption, Wireless OFF. vs Wireless policy to never sleep. And the most expensive was policy of sleep when screen turned off.

That's probably the case for 3g. But I'm using 2g and find 2g uses less battery than wifi in standby mode (with some background data sync).

Thanks, naenee, for the link. In case anyone is interested, I just made a simplified adaptation of RyanZA's guide, specifically for the DEFY: http://forum.xda-developers.com/showthread.php?p=22639770
I have trouble downloading large files using this ROM since when my screen turns off, WIFI is also disabled. How can I change it. I've been looking in the settings but to no avail.
Edit: Found it...you have to click menu when in the WIFI Settings, then choose advanced.
Edit2: Wifi is disabled when screen is turn off even if the Wifi sleep policy is changed to Never.
Any ideas?
then that is some kind of bug. because setting wifi sleep policy to never should behave as such.
related note, setting wifi sleep to never greatly increases batteyr life, as said thru the forums, because back on 3g the data kills your battery much faster. so allowing wifi to stay on makes a huge improvement on battery.
for example if you leave wifi on overnight, you might lose 5% total. but if it switches back to 3g overnight, you might lose 20%.
is this bug confirmed?
me too have same problem with SuperAosp (i will test with other rom....)
My WiFI Sleep Policy is set to default (After 15 min) however the WiFi is always on. The icon is there when I turn my screen on. Checked the battery usage graph also, and WiFi is always on (as long as I don't turn if off manually).
I have a stock ROM, the latest European stock ROM.
Is this a bug? What does 'After 15 min' actually mean?
I believe it means the wifi will turn off 15 minutes after the screen goes off, and then back on with screen on.
I thought so too, but mine isn't doint that.

I know there was a recommendation to set "Never" as the sleep policy. I can't find that post unfortunately. I know on my Desire with CM7 it resulted in better battery life, counter intuitive but......
I know. I've had it set to Never on my Desire. But now I'm seeing longer standby with the current setting (After 15 min) on my Sensation compared to the Desire. Although I suspect it isn't working and it's actually never turning off.

Lol, same upgrade here. TBH I've left it at Never and not tried the other policies.
I use WiFi when at home, I'm on a 3G data plan ( I'm guessing WiFi sleeping means I wouldn't get updated Gmail. Or does it revert back to 3G ?
WiFi sleeping means going back to 3G, yes.

Thanks, might just try it and see.
Does anyone think that instead of going to sleep after 15 minutes of the screen being turned off (regardless of whether there are background apps that have active internet connections), the WiFi actually starts sleeping after 15 minutes of idle time? I think this would be a better efficiency algorithm, so, as long as you have apps that constantly use the internet, keep WiFi connected, but when no apps are doing auto-sync or any background data, only turn on WiFi when manually using the apps..
Applications can be programmed to call for a WiFi lock. If any active application does so, WiFi won't shut off when the phone is asleep.

I remember that old tips thread. It was set your wifi sleep policy to never. Install spare parts+ or pro and set end button behaviour to sleep. And something to do with Market app. Settings->notifications-> uncheck the box. For some reason market notifications were not allowing your phone to go to sleep properly or some garbage like that. Its worth a shot.
Hi guy, my wifi won't turn off when my Xoom is on sleep. I have set the settings of 'keep wifi on during sleep' both to 'NEVER' and 'ONLY WHEN PLUGGED' but nothing happens. Wifi stays on and keeps draining my battery life. I am running rooted with the latest version of nightly 62 and I've been having this issue since 55. I have reinstalled, flashed, factory reset, wiped my Xoom.
Is anyone else having this issue? What should I do?
From my experience, wifi stays on for a little while longer after device sleeps. However, some apps in background may trigger wifi back on again. So I turn off wifi when i go to bed. Actually i notice wifi itself will not drain much battery, 1-2% for 10hr. It's the host apps sucking the juice.
I am not an expert though.
OK i've also checked it out and as you said wifi turns off after some time. My main problem now is that my battery life won't last more than 3-4 hours on wifi.
I have posted my battery stats with use of web browsing and watching pictures on gallery...

What do you mean "no more than 3-4 hours"? In your battery chart, you can get more than that even starting from 75% battery.
What I wanted to say is that I think my battery won't last more than 4 hours with wifi on and some serious usage.. from my stats as I can see I've been using it 5 hours but I only had screen on and browsing the web. I think there will be a huge difference if I am watching a movie or playing a game.. I don't have the time to check it now but I will post my results in some days..
According to my previous battery graph do you see any problem or something less from what your Xoom battery holds? Does this battery drain seems normal to you?

I think you'll find it will stay on for about 15 minutes. There is some setting in a system database (using a sqlite editor) that can be changed to bring this down. I doubt Wifi is what's draining your battery. Are you synching email via activesync or running other stuff in the background?
I am only using my yahoo mail from the EMail app. I don't know if it uses activesync. I have set it to check emails every 30minutes.
wifi not turning off
Edit: I found the wifi sleep option in ICS. Google sure did a great job of hiding it. See attached picture for anyone else having wifi staying on during sleep issues.
So there are three options
Keep WiFi on during sleep
1) Always
2) Only when plugged in
3) Never
What option to set if i want Wifi to turn of after some time of when phone sleeps. Previously i had set the option to 15 minutes but that option is not available in ICS and i m having a hard time understanding how these options work on my sensation.
Can anyone explain what each of these options do ?

My guess:
1) Always: WIFI always on no matter awake or asleep
2) Only when plugged in: WIFI always on only when plugged to power
3) Never: WIFI will be off if asleep (my current setting)
That was it

For an app to change wifi sleep policy, it needs the WRITE_SETTINGS permission.
Hi all,
A coworker bought the SGS3 on my recommendation and its battery life is absolutely horrendous. He went into the advanced wifi menu and changed the one setting to Never as was recommended here. But with wifi manually turned off it will just turn itself on like every minute. Then it goes back off after a few seconds then it turns itself back on after a minute and repeat, etc.
I can be in the settings menu looking at the wifi screen and the toggle is set to off, and it will just turn itself on.
I'm thinking this probably has something to do with the terrible battery life. He can only get to about 2pm each day before having to recharge and he is not a power user. something definitely wrong with the phone.
The phone is running stock software and is on the latest update LHE not rooted or unlocked.
Any suggestions would be welcomed.

There is a thread on this already: http://forum.xda-developers.com/showthread.php?t=1878779.
For me the issue was Tower Defense, which had in it's permissions that it could change the WiFi state. I suggest you look through all the recently downloaded apps for one that can change the WiFi state.

Yes, I saw that thread. I've gone into the wifi advanced settings and made sure all the auto-connect and wifi data hog settings were set to off. nobody has found out the definite cause of this? He doesnt have Tower Defense installed. It's obviously a flaw as tons of people have this issue.
It's very disappointing because it's ruining an otherwise good phone. Who wants a phone that with only light usage is dead everyday by 2pm??
