I have just upgraded my iPhone 5c to iOS 8.4 and my phone started acting wired its rebooting itself after 3-5 min when ever I am charging my phone and my battery usage is not being displayed properly it shows 100% all the time even after using it for 4-5 hrs. Recently I have also notice that when ever i shake my phone there is a strange sound coming out of my phone like something is dislodged in my phone. Could this be a problem with battery or something else or do I have to replace my old battery.

Hi, This could be an issue with the battery, the gas gauge of the battery may be damaged, and that’s why you are getting improper readings. The battery itself could be damaged also, try replacing the battery and it should be ok. :-)
