[Q] Auto switching off Wi-Fi when in standby

---

Hi! I'm an new owner of an Xperia S, and am really proud of it!

I was just wondering if there's a way to automatically turn off Wi-Fi when the Xperia S is in standby mode. I found that keeping the Wi-Fi on while the screen is off drains the battery quite significantly. I know turning off the Wi-Fi manually is an option, but I always forget to do so.

On my previous phone, the LG Optimus 2X, the Wi-Fi automatically switches off when the phone's screen is off in about 5 minutes.

Are there specific kernels for the Xperia S which supports this?

Thanks in advance!

You can use "juice defend" in play market to do this

go to wifi settings and in advanced there is an option to turn it off while the screen is off.

option available in wi-fi settings

go to settings/wireless & networks/wi-fi settings now tap on menu (right end capacitive button) then click on Advanced/wi-fi sleep policy there you find options
1.when screen turns off
2.never when plugged in
3.never

i think you should go for option 1

Wow! I didn't know of that hidden advanced menu. Thanks a lot guys!
