iPhone 5s not charging
I got in a Iphone 5s that's not charging. The charging symbols pops up when i plug in the cable but then it doesn't even show its charging. It just notices when i plug it in. I replaced the battery and charging dock already and still the same result. Anyone have an idea what could be the problem?

Is there a way how i can be sure it's the U2 charging chip? And how easy is it to replace for someone with a little bit of microsoldering expirience?

I removed the chip and tried to clean it good. I attached a few pics, what do you think? I welcome all feedback because i'm still very new to this. Waiting on the parts to arrive to solder on the new chip.
Is this a good question?
