Chosen Solution

i have an iPhone 5c that worked great until I did a firmware update from 8.1.1 to 8.2, now the battery drops 10 percent in 30 mins to an hour. I have to keep charging it, yet it takes like 3-4 hours to charge, I installed a brand new high capacity battery and replaced the lighting usb assembly port. and still the same problem, does anybody know the cause of this?

High capacity batteries are not highly recommended check your location services and background data

This the troubleshooting order I would follow:

  1. Try a new battery
  2. Reset software
  3. Replace U2
