Q: My brand new 6s won't charge via the wall charger; my 5s had done the same for about the last 6 months. I can only charge through the computer. I thought when I had all new parts that would help; suggestions?

Have you tried using a new plug base, or a different power outlet at the house? How about a different cable? The new iPhone 6s should have come with new charging base and cable. I suggest a different power outlet.

Dmatine,

Follow the steps listed in: If your iPhone, iPad, or iPod touch won't charge - Apple Support

If none of that works, since you have a "brand new" iPhone, be sure to Contact - Official Apple Support

The only way the device would not charge when plugged into the wall, but would charge if plugged into the computer is if the plug block, cable, or wall plug were defective. If you have tried an alternate to each of those, I suggest you make an appointment at the Genius Bar, bring all of that content and have the device and its accessories tested there. This makes no sense to me.

Good luck.
