Wired charging is the most efficient and environmentally friendly way to power your smartphone—it takes less time and uses less electricity than wireless. Charging pads are more convenient—set your phone down, and you’re done.
One caveat with wireless—you should ensure that your phone is correctly aligned on the pad. An off-center phone on a wireless charger uses more electricity to power up and can heat the phone’s battery so it degrades faster.
Whether you want convenience or efficiency (or both), you’ll find all the options you need at AT&T.
