After the iOS 7 install on my iPhone 4S, my battery life is markedly worse and my phone will not connect to my home wifi. Every other device, including my wife's iPhone 5 and two iPad 2's, still connect perfectly. Please help. I wish I could go back to 6.1.3.
I've had issues since the upgrade too-messages wouldn't load, phone locked up and would turn off at random times. Then I noticed my data usage going up a ton in one day and checked and it wasn't connecting to my home wifi. Called tech support and they went through all the troubleshooting they could find and nothing helped. Had to go upgrade. You might try to reset your network settings, but that didn't help with mine
