I phone 5 wont turn on
Yesterday, I turned my fully charged iphone 5 off then turned it back on an hour later, or at least tried to. It said my phone need to be charged so i turned on my charging case and waited for it to turn on but it never did. I got home and tried three different chargers and it would show that my phone was charging but it would never turn on. Now i don't know if this is related to the effective power text because i could not find anyone with the same problem. Any help would be appreciated, i will probably just go into the store tomorrow if i don't find a solution.
iPhone 5, iOS 8.3
