Hi, I have iphone 5s with weak gsm signal. Original owner bought new battery and dock connector. I replaced them with original battery and dock. I also put new screen. I have signal only 1-2 bars and iphone is very very hot. Iphone had never water damage. Battery drains fast too. Any solutions?

Do you know were the original owner bought the parts from. If the battery and dock connector are bought from a cheap supplier that could be your cause of the phone getting hot and also could effect your performance of you phone.
