Charging Circuit Failure (Gas Gauge), Micro Solder help
During a battery swap on my old iPhone 8 I damaged some of the soldered-on components nearby the data connector for the battery. Now the iphone battery won’t charge, and the device will only stay on for a few seconds before rebooting. Most users on the forum came to the conclusion that this was a damaged charging circuit/data input for the battery.
Now almost a year has gone by, I have a new phone and a lot more free time and I thought to myself, this seems to be a great little project to get me into micro soldering, something I’ve wanted to do for a while. I’ve been watching some tutorials regarding this issue specifically, and I wanted to ask you all if I have the right idea or am completely lost.
Lets begin,
So here is an image of the phoneboard view of the circuit at hand:
the area circled in blue represents the components which have fallen off the board thanks to my aggressive connector attaching. I’d assume these are just resistors but I honestly don’t know (if anyone would like to tell me I’d love to hear), and the one on the right connects to the top right 3 prong component (MOSFET maybe?), and then connects to the main processor (not shown in photo). My thought process, was to solder a short wire (represented in red) between those two terminals. Would this work, or am I completely in the wrong?
Also here is the photo of the board through my microscope:
Esta é uma boa pergunta?
