iPhone 6 Plus - Lightning port and battery replacement
The lightning port failed on my 2 + year old iPhone 6 Plus. The battery was also getting weak prior to that and it would barely last a day without charging.
Following along with the 'iPhone 6 Plus Lightning Connector and Headphone Jack Cable Replacement' video made this repair fairly simple. I took my time and slowly and carefully followed the videos detailed instructions.
Set aside 2 hours and take your time. Watch the repair video in its entirety at least once before following along.
