Anandtech took a closer look at the new iPad's 42.5 Wh battery and discovered the battery is fantastic for those using the device as a mobile hotspot. In a series of tests, they ran the Verizon WiFi+4G iPad from a full charge down to zero with the screen off. Total time was an impressive 25.3 hours on a single charge.
Overall, the battery performs as expected. The retina-equipped iPad has a run time that's slightly less than the iPad 2, and you'll get an hour less juice on LTE than WiFi.
