I downloaded the IOS 5.1 fix for my iphone 4s this morning and instead of fixing the problem of battery life it seems to have made it worse. I've done all the recommended changes to my settings to preserve battery life but no joy. My next task is to run the phone down completly and then recharge it. The apple web site is inundated with this problem continuing even after the update. I'm starting to think of going back to my blackberry..! hhmm maybe not ! I expect they will fix it in time but at the moment its a real pain. I remember the old big engined cars (yep I'm that old) where you could watch the petrol guage go down as you drove along.. I'm doing the same with my Iphones battery power meter.
