Why isn't my phone charging?

Dear community,

My iPhone7 Plus had a - or so I thought - faulty port. Prior I had noticed that I have to hold the charger in a rather odd angle to get the phone to charge at all. At some point, the battery ran out and the phone hasn’t switched back on ever since. Occasionally, it showed the “red battery” (minus or with the lightning cable) on the screen, yet, never charged to the point where it would switch back on. Hence, I went ahead and replaced the port. I had previously successfully replaced the battery and also added a new “water-resistant“ seal.

While I am no expert by any means, I was careful and everything appeared to have gone smoothly (no screws left over, didn’t tighten screws overly tight, used nitrile gloves and was overall careful). The phone, however, won’t charge, let alone switch on. It won’t even show the aforementioned “red battery” anymore. So far, ifixit has kindly sent me yet another replacement for the port but the issues persist. The very least I would have expected was that I would get the “red battery“.

I was wondering what the underlying cause could be? Did the logic board take damage somehow? Is the battery overly drained that it simply won’t react anymore? Is it worth getting an iPhone 7 plus-appropriate DC power cable to bypass the battery to see if the phone will at least switch on? May a battery (re)activation board be useful?

Many thanks for your input.

Happy New Year,

Georg

You would need to rule out the battery first. If it is not the battery it would point to a charging chip on your phone known as Tristar.

A Tristar replacement is straight forward but does require microsoldering skills and equipment.

Most repair shops offer this service and usually have access to a Tristar tester so they could determine if it has failed without taking the phone apart.

Thank you, Chris, for your valuable input. I will address the battery question first. As I mentioned, I replaced the battery - about 2-3 months ago -and all seemed fine. That doesn't rule out, of course, that it's the battery. :) In hindsight, I wish I wish I had kept the old battery so I could do that just now.

that’s what the battery testing board is telling me. I assume that’s ok?

I have never used one of those before but it looks fine. Charge it up and let us know if the phone boots.

Why isn't my phone charging? Part II

It boots yet doesn't charge. You might be right with the Tristar.
