Why is my phone over heating

@ashenafiabebe is it saying it is overheating or is it really over heating. Let us know what you have checked. Overheating on the board level, is usually related to short circuits. If it is overheating during charging, it could be the battery or the charging board. Use this video to replace the battery and the daughterboard. After that, re-evaluate.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
