My iPhone 4 with 32 GB and operating on iOS 7.1.1 has started running down way too fast. I have done everything listed in the link below and it didn't help at all. http://www.apple.com/batteries/iphone.html I have also deleted a ton of Apps. When I unplug it from the charger it is down to 95% in less 10 minutes. That's without me doing anything on this phone. It continues to go down rapidly. If someone has an answer it will be greatly appreciated. Thanks.
