Not Morgan related but this may help others. My iphone would not display a charge, though the battery was still showing 30%. Tried different leads and chargers to no avail. Then wondered if fluff or dirt from my pocket has got into the charging socket on the phone. So gave it a rub with my shaver cleaning brush...nothing. Little to lose, so attacked it with a cocktail stick, and finally, out popped a little compacted “worm” of fluff. Now charging fine. Have given it a squirt of contact cleaner just to finish off. I could easily have gone out and bought a new battery or even a new phone, all for nothing.
