Wifi Sharing chewing battery life

Got my GS2 on Friday. Charged it when I got home to full before turning it on for the first time.

Getting a bit less than 10hrs of battery life, which isn't too bad, but use hasn't been strenuous, so not thrilled.

I looked at the battery usage and WiFi Sharing has been chewing through my battery. When I was first setting up my phone I configured it, as I do use, but haven't since turned it on, or connected to it from my laptop.

When I started writing this new thread I see there is another thread on the Optimus 2x doing the same thing. Is this a bug in Android with Dual Core CPUs?

Wifi Sharing (mobile hotspot) is a battery hog on any Android device. Thats just the reality of a good feature.

Wifi sharing is a mega power-hog, as it is essentially making a base-station from your phone. So a lot of power is used as the wifi will be in use fairly heavily.

Same on every device. Hero used to get quite warm using wifi tether.

That's surprisingly good battery life for leaving wifi sharing on.. a 10 hour wifi hotspot from a phone is about the best you can get. Not even sure if those portable wifi routers get that kind of battery life.

Yes, I know it can use a huge amount of battery. But I haven't been using it. I configured it (ie, put in my WPA key, the same one I had on my Nexus One) so I could use it, but then turned it off.

I shutdown my phone last night (took out SD card to copy a bunch of music over quickly). Since I turned the phone back on, I haven't even been into the wifi sharing menu and it's used 15% of the battery.

I will try removing the config and see if it crops up again in the list tomorrow.

Cheers, Tim.

I also have this, but do not use the feature, nor do I start it, but it still keeps appearing.

Any advice?

It sounds like you might have left it enabled - mine is disabled and does not use up any battery.

This is the problem. Wifi sharing is off. I configured it, but it is off. I 'forced exited' it from from the battery usage menu after I saw it, but at some point it started again.

Force exit won't do anything, it will just start up again. Make sure the checkbox is disabled. If it is disabled, try enable it and then disable it.

Can't seem to replicate it here - when I disable the checkbox it turns off.

The same thing happened to me. I configured the sharing never turned it on and it was killing my battery. I checked a million times that sharing was not active but it made no difference the service was always running. Killing the service didn't work it kept coming back. I did a full hard reset and haven't setup sharing since and it has yet to be an issue.

Kinda sucks as I need this feature. This did not happen in my atrix which is a dual core phone aswell.
