iphone 4s battery not charging - fake charging? how to test - GSM-Forum

geekgirl123 · 03-03-2015, 04:56

HI, I have an iPhone 4s and it works fine except the battery does not charge.
I plug it in and the charging indicator is shown and it looks like it is charging but never does. I tried all chargers etc.

I replaced the dock connector with another one and it does not help. The batteries are fine, I tried two.

I think something on the logic board but I can't tell. I have a multimeter and try to follow the schematics on this forum, but can someone tell me exactly where to test the flow to see at what point it is failing? I want to try and fix myself. the connectors are so tiny, how to get the multimeter on them, and which ones to start with...I have no clue.
thanks in advance

So happy. I found a capacitor that is missing, under the battery connector... It is so tiny!!!!
I have microscope and fine soldering iron, so what do I do? replace or put solder across?

I can't post pics yet, but I will try to describe.
It is the second of 4 of the tiny capacitor. (3rd one is black). it is reddish/tan. Right under the battery connector.

sorry meant one that is missing, which is the 2nd one is black not reddish/tan.

its often better to purely give the name of the capicator resistor when explaining an issue, the schematics will give you this (eg. R1234 for resistor / C1234 for capacitor)

replace if possible, if not you may be able to jump if the component is not CRITICAL again schematics will tell you this...
