I'm having a very strange issue with my iPad and potentially iPhone. I have a Gmail account set up on both devices. Today, I noticed my iPhone battery drop in a ridiculously fast manner, from 90% to 50% in about an hour. I tried checking my mail and it would freeze up. I could back out to the home screen, but when I went back into mail, it was frozen. I turned the iPhone off, turned it back on and it would download my e-mail but when I went into mail it was frozen again. I turned the iPhone off because it had dropped all the way down to 10% battery and was getting hot. I get home and try to check my mail on my iPad and it shows no new mail, which I know is wrong. In fact, it has nothing since 5:23 p.m. yesterday. This is the really weird part, when I go into settings on the iPad and try to access the Mail, Contacts, Calendars tab, the screen freezes and won't load. I can back out to the home screen, but I have to double tap the home button and kill the Settings app in order to go back into settings and see anything else. Any idea what could cause this? Better yet, any idea how to fix this?
