iPad Air Continues to Offer 24-Hour Battery Life as LTE Hotspot
For those customers interested in taking advantage of the iPad Air's ability to allow other devices to tap into its LTE data connection, Apple's latest iPad continues to offer a robust 24 hours of battery life as an LTE hotspot, far more than dedicated MiFi hotspot devices, reports AnandTech.
While the 24-hour hotspot battery life is not new to the iPad Air, confirmation of the feature is comforting given that Apple has taken advantage of more efficient technologies to reduce battery capacity in the iPad Air by nearly 25% compared to the previous two generations without compromising performance.
I set the iPad Air up as a personal hotspot, wirelessly tethering it to a 13-inch MacBook Pro with Retina Display. 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.
A total of 24.08 hours and over 8GB of transfers later, the iPad Air finally died. Just like last time, you'll likely burn through your monthly data allotment before you run out of power.
The iPad Air is of course a much larger hotspot solution than dedicated MiFi devices, but for those who may already be carrying an iPad Air to use on its own, it continues to provide a solid option for delivering cellular data access to other nearby Wi-Fi devices.
