Member: 2573586 Status: Offline Thanks Meter: 0 | iphone 5s u2 issue few questions Iphone 5s none charging issue. I did replace tristar, didnt help... (I am idiot it wasnt tristar ) Than I checked near batt connector: FL11 ; C279 are missing.... I did solder back FL11 but no yet C279 I will do later.. (I dont think C279 is very important) So I did test with multimeter. So, with usb lead and without batt, on charging pin I am getting only 0,5V on battery pin +4.89v, but there is no battery at all?? It`s normal??? What could be wrong? Bad tristar soldered? Why is +4,89v? Any advice pls Thanks |

Member: 2573586 Status: Offline Thanks Meter: 0 | there is 3 pins on battery connector. 1 pin its ground, 2 pin its for charging, 3 is vcc+ from battery. So 2 pin is 0,5v ; 3 pin is 4,89v (battery not connected at all). Connected only usb lead. |
