My phone dosent charge

@klasnetaw there are a few possibilities. The first one would be a bad battery. Replacing it will repair this. Next one is a bad charging port. clean it of any debris. Use a few drops of high grade isopropyl alcohol and a few puffs of compressed air to clean it. If that does not work you may have to consider changing it. The charging port is soldered to your phone's circuit board. so it would require you to desolder the old pone and replace it with a new one. The other possibility is a bad power management IC on your circuit-board. For that you will need to have some special tools and skills to work on it.

Since iFixit does not yet have a specific guide for this, use something like this video Replacement batteries etc. are readily available at many online stores.

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 a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
