The web browsing test was not impressive as the talk time. The battery of Xperia Z Ultra went flat after five hours and 23 minutes of web browsing.

The large-screen handsets such as Galaxy Mega 6.3 and Ascend Mate both offered browsing over eight hours.

The Xperia Z Ultra, as the results suggest, offered video playback up to eight hours and 45 minutes. There was a marginal difference between the video playback life of Xperia Z Ultra and Galaxy Mega 6.3, which stayed for eight hours and 34 minutes in the same test. But Huawei Ascend Mate was approximately three and half hours ahead of the Z Ultra. Motorola's Razr Maxx running on Ice Cream Sandwich was the winner in the battery test with 16 hours and 35 minutes of video playback.

The Xperia Z Ultra scored a decent endurance rating of 52 hours, which means the device can run for 52 hours on a single charge given one hour each for talking, web browsing, video playback and leaving the phone in standby mode for the rest of the time.
