When to replace the main flex
A main flex is worth replacing when a new charging port has not fixed a charging fault, or when the cable is visibly creased, torn or corroded after a drop or liquid damage. Disconnect the battery first, unplug both ends of the old flex, then peel it away gently as it is often held with light adhesive.
