For me, the wall charger seems to charge faster.
I would think charging through the wall charges faster. Plus also another tip ....your phone may charge faster too if your phone is turned off
The wall charger will charge the phone faster than hooking up to the computer. The wall charger has an rated output of 850ma where most usb ports on current computers are rated at 500ma max
Your fastest charge is via electrical outlet. If you want to speed that up turn the phone off and charge.
