Chosen Solution
Hi All, Have had a couple of strange issues, I thought I’d check in with the community and see if anyone has experienced them.. An iPhone 6S and an iPhone 7. Presented as battery replacements. After replacing the batteries, the phone would charge as normal. However when the phone goes flat, it won’t charge anymore. Battery life was as expected of a new one.
The issue is the Tristar chip (controls charging and USB circuit) needs to be replaced via micro-soldering. A classic symptom is the battery going flat then the phone does not charge flat batteries. Another dead giveaway is not seeing an apple logo when plugging in the charger with the battery unplugged. Like others said make sure MFi certified cables are being used because they have surge protection built in them via the small chip in these cables. Unfortunately iPhones don’t have surge protection so the Tristar chip basically acts like a fuse that gets damaged. Just to verify its not showing the low battery screen right?
Hello moffit, There are a few possible issues, but they should all be easy to fix if it is the case. First, it may just be the charging cable. Cheap, third party, gas station chargers are not very good, nor apple MFI certified cables, meaning they can possibly damage your phone or throw its battery cycles out of whack. If that is not the issue, the repair place you took it to could have broken the charging port by accident. This would hold them reliable, but it is a fairly rare occurrence. Lastly, it may just be the battery not wanting to charge. This would also be the repair places fault, but it is not likely. Hope this helps!
There is few possible belong to that faults.The common problem with SWI issues.
