My laptop doesn't go to sleep mode. I have tested this, and if it is plugged into the Apple supplied charger, the wi-fi doesn't go off, but if it is plugged into the computer USB interface, even if the computer is actively in use, it still shuts off the wi-fi after a few seconds. Charging continues, however.

That would indicate the USB port is not putting out sufficient power to both charge the phone and keep the WiFi radio alive. Given the choice, the phone should try to charge. Doing otherwise could actually result in the battery being drained while connected to USB if the available power is too low.

Good thought. Maybe that is the case as the USB ports are only rated for 500ma. Works fine for overnight charging.

Settings > general > network > disable 3G " the first choice " ,

you dont have to use 3G while you have wifi , it decrease battery and just use 2G for calls and internet 😉

my iPhone4S 16GB Black was overheated because of it ..

You really nead to read the thread you're posting in.... Start from the beginning in this ancient thread, when the iPhone 4S, iOS 5.0 did not have that option. Even with iOS 5.1.1, certain carriers, such as AT&T, no longer allow disabling 3G because they are phasing out their 2G service to make room for 4G (LTE)

It is possible!

Settings -> General -> Cellular -> Cellular Data Off

Thank you for your wonderful insight but you will note this subject is 9 months old and has been fixed for some time.

Did you honestly think we were all stupid?

Thanks Larissa!

So, pblo, sometimes in a thread that is 40 some odd pages the answer can be difficult to find so it is helpful if the answer is posted multiple times... but thanks for being rude to somebody who was just trying to help anyways.

It's a bit strange that you open a new account and your first post is also to be rude to someone. Are ypou Larrisa's boyfriend?

You are more than welcome - Please feel free to give me the details of any other numpties that need things explaining to them.

Of course he is not my boyfriend. I would never develop any positive feelings for somebody with such a negative and shallow attitude.
I wish him all the best, though.

Easily done. Just say it in front of a mirror.

Hi, i don't have the option to disable 3G, why is that ?

If you telecom service provider doesn't support anything less than 3G you cannot turn it off.

Did you READ this thread at all before you posted this question?

Settings -> Cellular -> Cellular Data

This will turn off your 3g, wifi, 2g all but amazingly i can turn on wifi alone and accessed internet. It worked for me...

Description for disabling Cellular Data

Turn off cellular data to restric all data to Wi-Fi, including bla bla bla... this means you can only access Wi-Fi no 2G or 3G... hope this helps

I don't know if it's a UK thing, but I couldn't find "Network" or "Cellular Data" in my "Settings > General".
Though I did find "Settings > Mobile Data" which I could turn OFF.
