Hello, my peeps on the ifixit fourms I put a iPhone 5c battery in my iPhone 5s and now it wont charge will putting a iPhone 5s apple battery in it make it charge again or and fixes Thanks, Aiden

Both 5C &5S have same battery.By seeing that there is something mistake on SWI lines.Check the center point of battery that connect properly.

I think it’s either a bad battery or missing components right above battery connector as shown here:

Have you checked with a program such as CoconutBattery / 3UTools to see if the battery information / health is being read properly? Reposted as it is similar problem from other answer.
