Charging slow and the battery dies quickly Where the problem

hello Senpai,

if you are charging and the electricity is losing power or even the phone consumes more than it has time to recharge, it may mean a short circuit to ground in the logic of the motherboard or other connected accessory, e.g. tape with the charging port, camera, screen, etc. If you do not feel up to the problem yourself take the phone to a good repair shop. However, if someone offers to replace the battery or a screen - run away from this place and find the right one :-) where technican will got enough knowlange for repair your iPhone.
