Overview
What this part is
The iPhone XS Max charges and syncs through a Lightning port built into a long flex cable that runs along the bottom of the phone. Worn pins, bent contacts or liquid damage can stop the phone charging reliably, even with a good cable.
Before you buy, clean the port gently with a wooden or plastic pick and try a different cable and plug. If charging still drops in and out, this brand new charging port flex made to fit the iPhone XS Max is the usual fix.

FAQ
Frequently asked questions
Will this fit my iPhone XS Max?
Yes, if Settings › General › About shows iPhone XS Max. It fits models A1921, A2101, A2102, A2103, A2104.
Does it fit the iPhone 11 Pro Max?
No. The iPhone 11 Pro Max uses a different charging port flex. Only buy this for the iPhone XS Max.
Will it fix slow charging?
It fixes charging faults caused by a worn or damaged port. If the port is fine and the battery is worn, a new battery is the better fix.
Is it made by Apple?
No. It is a brand new, OEM-quality charging port flex made to fit the iPhone XS Max, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The flex sits under several other parts and is glued to the frame, so it needs care to fit without damage.
