I have recently bought an iPhone 5 16GB. But am experiencing very low battery backup. It loses 8-10 percent avery 20 minutes while i make calls or use net. I have minimal calling and average 3G usage.
I have been using iphone since a long time, earlier have used iphone, iphone 3gs, iphone 4 and now iphone5 and have found that iphone 5 is giving the worst backup time for a fully charged phone on minimal usage.
I HAVE ALREADY TRIED RESTORING, BUT PROBLEM PERSISTS.
