Battery not working and running iPhone without battery
I Want to ask you, my iphone 4s, 4x already replace the battery, when the battery is completely discharged, the battery would not charge at all on, when in turn on without charger only black blank, but when I plug the charger iphone starts normally and only up to 5 minutes he will restart again, and the battery indicator lights up 100% like without batteries, I like the battery is not working, but when I change the battery still has its new to my iphone, but can burn quickly once the battery runs out and the conditions of temperature can reach 37 degrees Celsius.
Please take the master of the solution. Thank you
Afriyadi, you did not tell us if anything happened to the phone prior to this. It sounds like a problem with the charging circuit. I'd start with the dock connector (since you already changed the battery with a new one), then open the phone and check all the charging components. This could be caused by a failed/damaged charging coil. Check for any physical damage, or if you have the knowledge and tools, check for function. You want to start by checking 3 inductors. For that, of course, you need a multimeter, or at least an ohm meter, to check for continuity. I hate to refer to those as fuses, but they most certainly control part of the charging circuit. First one is reference designator L3, it is a FERR-120-OHM-1.5A inductor. L4, right below it , has the identical value. Next would be the charger inductor L28 2.2UH-1.8A-155MOHM. All of these are pretty much available at mouser. com or digikey.com. Check the Diode D604, located just above L28. Hope this helps, good luck.
