iOS 6 battery drain and overheating while 3G

Does anybody observing than iPhone (mine is 4s) drains battery very fast and became hot after upgrading to iOS 6 when surfing 3G? Any suggestion how to "fix" it?

I'll probably just have to suck it up and do a restore. What I've found is that it only happens when I tether the iPad to my PC and it doesn't seem to matter whether iTunes is open or not. It's only happened since iOS 6.0 so something changed and it may well be corruption somewhere even though I don't appear to have the errors you mention. I haven't had to do a restore since 5.0 blew up my iPad 2 so that's not too bad but update related issues are getting annoying. Thanks much for the reply.

Hi,

I'm using a iPhone 4S and when the drain cycle starts (usually when the 3G signal is bad) I close all applications that use the network (email, facebook, etc) and, mainly, I disable the location service. I did a few times to reset the network but I think it worked by turning off the location service.

Regards

I have no idea what triggered this, but for the past 2 days my iPhone 5 first with iOS 6.0.1, and later with 6.0.2 has started overheating and draining battery like crazy. I have to charge it three times a day now.

It would be nice to get some official feedback on this issue.
