Just the other day, I was without Wi-Fi access and was tethering my iPhone to my MacBook Air. It's a great feature. I usually feather using Wi-Fi for convenience, but started to wonder if tethering over USB or Bluetooth would make a significant difference in speed or reliability. Turns out, iMore just did some testing and it does.
There are three ways to tether to your iPhone or iPad and they are USB (via Lightning or Dock cable), Bluetooth, and Wi-Fi (personal hotspot). But which one gives you the fastest speed? Which one gives you the most reliable connection? Which one saves you the most battery life? Which is the best way to tether to your iPhone and iPad?
