You can turn off 3G Data this way. Settings/General/Network/Cellular Data/OFF.
That will give you voice and SMS (turn off imessage too). You will not have Edge data either. But if you then turn WiFI on in your home, you will have data there.
You can then test whether your weak data signal is the issue. Of course, you will still have 3G voice. If that is a concern turn that off too. Of course all of this is just to test what is draining your battery, not a way to operate.
thanks bro, but i allready checked all that. That is definetly the problem, there is a huge thread on the apple support forums about this.
And turning cellular data off is rediculous, i need to turn it back on every time in leave the house again then. And also cellular data isnt the same as 3G. When turning off cellular data it still connects to 3G and then back to edge constantly. Data isnt the problem, the network between which it switches is!
How can I turn of 3G voice?? Cheers
A simple turn of 3G switch, like there always was would solve mine, and for thousands of others the problems!!
