Hi, I'm new here and would like to ask a few questions. Does the iphone 6 have a better battery than the iphone 5s? I recently upgraded mine and I noticed that it uses the battery faster than my old 5s. Last night after a full charge, I read a few blogs and went to sleep, awoke to check on my phone and it had gone down to 30% and it happened to shut off or rest on me. Could it be iOS 8? I could try restoring it to manufacturing settings if that helps. Suks cause I never had any probs with my 5s. Anyone experience anything like this? Jackie.
