Battery Usage

[Debs3186]

I have a 5s and have my brother's 5s on my account.  Both these phones have a dead battery within hours of charging with little or no usage.  I never had this problem up until about a month ago.  My phone is about 1 1/2 years old.

This is very unusual at the 18 month mark and for both phones, even with continuous use over 90 minutes. Do you have an Apple store near you? If you do, I would take it in to the Apple Store Geniuses to review.
