Hi all,
I just got a Droid 2 Global today and I notice if you leave it alone for a while (which is hard to do with a new phone) the WiFi will turn itself off. The first thing I do with new Android phones is turn the WiFi Sleep Policy to "Never". And that is what I did today, but it still appears to be sleeping.
When I wake the phone I notice that the WiFi is off (Both up in the notification bar and the widget is dark) and the 3G is off as well. The only that is showing is bars. In about 5 seconds the WiFi will turn back on and connect.
Now this only happens if I don't play with the phone for a while. Turning the screen off and back on the WiFi will be on like normal.
As this annoys me that it is doing it, it is the 3G is off at this time as well. Which means the phone isn't getting any data during the period that it is off. Which isn't good since I rely on Google Voice for all of my texting, which won't come in unless there is a internet connection.
Any help on this will be great,
Thanks
I did find out what was going wrong last night. In Settings>Battery Manager>Battery Mode it was set to Nighttime saver. That would have been bad because I work 3rd shift and I'm up and using this mainly at night.

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
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 guys, i noticed an irritating problem with my One S after a few days of usage. My WiFi turns on at random, and remains on when my phone is in sleep mode. This occurs when I have 3G on. I have turned off using WiFi in sleep mode.
Anything else I can do? I feel like this takes a toll on my battery life.
I wouldn't worry too much about wifi if you just got the phone.
While its connected it shouldn't use up the battery. Afaik
It's the searching that uses battery.
yeah my wifi is on 24/7 i dont experience any drain through it..
you could put a toggle widget on one of your screens to turn it on / off.
it shouldnt be switching itself on it you manually turned it off
But it does exactly that! It turns itself on even after I have manually toggled it off. irritating as it searches for open networks even if I have data on. How do I resolve this hmmm
Maybe Tasker would help?
EDIT: Still unsolved - see post nr3
"keep wifi on during sleep" is set to "only when plugged in" - it worked like a charm in lollipop (it switched off wifi after some seconds of disactivity), it doesn't now.
EDIT: In lollipop after some seconds of inactivity wifi was turned off, that was proper behavior I guess... It is not working in Marshmallow.
1. GSAM Battery monitor seems to have problems with showing WiFi activity on Marshmallow (shows "on" when switch is turned on, but it's inactive). I used build-in Marshmallow graph instead (settings > battery) and that showed me, that WiFi is indeed being turned off during sleep.
2. In my Lollipop WiFi became inactive just seconds after screen turned off. I expected the same behavior from Marshmallow, but it is different. It seems, that now wifi is turned off after 20 minutes of inactivity (checked few times).
Am I right about deactivation timer in Lollipop / Marshmallow? I guess It's much better now, since in Lollipop I sometimes had to keep screen active in order to install all upgrades, etc. But for me 5-10 minuted would be perfect instead of 20 minutes. Any way to change that?
After some weeks I have to say, that problem is unsolved. I can't repeat the situation when wifi was turned off when phone went to sleep.
I tried safe mode - the same effect, wifi is on when screen is off. Even after I am going back home with phone in my pocket it automatically connects to the router (with screen turned off, phone should sleep)
Does anyone have similar problem?
Bump - more info.
When I turn off Wifi my phone uses 1% or less battery during night. With Wifi turned on it uses 5-10%. If it worked like it should and turned off wifi when screen is off it would use the same amount of battery life as when wifi is off.
Could anyone at least confirm, that I am the only one that has that problem? Your marshmallow Nexus 5's are working as expected?
The wifi icon disappears after few minutes of screen being off after locking. I did set wifi to be on during sleep. Does anyone else have that issue ? I have a SIP client installed on my phone and need wifi all the time so that is a pain.
Mine does the same thing. I think it might be because I have the *intelligent power saving* checked in "power management" in settings. I think the phone disables data every so often to preserve the battery. Haven't tested my theory by un-checking, but I remember this happening on my Blu studio energy.
I have intelligent power disabled.
I think I am getting this on my phone. Sometimes on wakeup it forgets it is connected to Wifi and apps and chrome won't update. I usually just turn airplane mode on/off to fix it. Still, it is annoying. Doesn't seem to happen with LTE, at least.
