We can fix 90% of iPhone charging problems by cleaning the USB port. We have tools we have designed that can reach deep into the port for a good clean out. We don't recommend DIY cleaning simply because of the ease in which the port can be damaged.
We can replace the lower USB power flex cable if necessary. We use Original Quality Parts. We do not use copy cables.
This repair is usually needed if your iPhone is fake charging, stays at 1%, or will not charge from completely dead. We offer this repair for iPhones 5C, 5S, 6, 6 Plus, 6S, 6S Plus, 7, 7 Plus, 8, and 8 Plus.
