Hi, I'm experiencing the same problem... Few weeks ago I replaced the screen, and the phone was perfect until two days ago when I didn't charge anymore and I decided to switch it off when the battery was 5%. It didn't turned on anymore... only the vibration works too much (each five minutes!). To be honest in the last period the charger didn't work well... I had to put it in a specific position to let the phone charge. Now I would like to change the battery but the original one that is on amazon is quite expensive and I'm not sure that in the end the phone will work. Did you solve the problem? How many are the possibilities that chancing the battery I will get my phone working again? Thanks a lot, Miriam
