That iPad Air you bought over the weekend is good for a great many things, but if you happened to invest a little extra into the Wi-Fi + Cellular model, you'll find it has the potential to be the best LTE-equipped mobile hotspot ever.
AnandTech is reporting that the iPad Air with Wi-Fi + Cellular clocked in with an impressive time while used purely as a personal hotspot with the screen turned off, despite having a smaller battery than the previous model.
While the third-generation iPad lasted 25.285 hours on a single charge, the data-equipped iPad Air clocked in at 24.08 hours after transferring 8GB of wireless data to and from a 13-inch MacBook Pro with Retina Display.
"I set the iPad Air up as a personal hotspot, wirelessly tethering it to a 13-inch MacBook Pro with Retina Display," explains Anand Lal Shimpi. "I started a constant 100KB/s transfer on the MacBook Pro (2x the transfer rate of my iPad 3 test) and with the iPad Air's display off I measured battery life.
"Last time I chose 50KB/s as it was the average transfer rate across our old WiFi web browsing battery life test, I doubled the workload to be more reflective of more strenuous demands. In reality I'd expect to see a burstier usage profile, but that's something for me to test down the road."
So there you have it, folks: Despite reducing the battery from 42.5Wh to only 32.4Wh, Apple still managed to nearly match the personal hotspot time of earlier models on the iPad Air.
