I had a similar problem with my Iphone a few months ago, and I eventually figured out that when my phone did an automatic system update it activated Siri in ALL my apps! So basically Siri was on all the time waiting to hear for commands, using tons of battery power. Go to your apps and check each setting and make sure that Siri is not activated on anything you don't want.
@whitewave, so glad that I helped! It really frustrated me to no end for a few weeks and by some luck I checked all my settings and apps and there was my answer!
Omg @whitewave! My battery is at 92%! I had no idea!
I know, who knew you could check battery life!
I’m so glad I asked.
I got my 7 when it was brand new and it just died in December...my battery was having issues as well, after my phone died I went to Verizon and they told me that a iphone can only do so many updates before they break....mine broke...I had to get a new one..I was not a happy camper, I now have a 11 and it took me forever to get use to..hopefully yours doenst break like mine
