In BaseMark OS II we see that the Venue 10 has a fairly average result. In any case, the video playback battery life on the Venue 10 is more than adequate to spend a flight or a car ride watching movies, and I don't think users will need to spend much longer than that. What's surprising is that the iPad Air 2 with its LCD display is able to outperform the Venue 10 at both brightness settings. The relatively small difference between the two results highlights how the high display power usage at a high APL is what leads to the short web browsing result. The lower APL of films compared to black text on white webpages allows for a battery life of 11.48 hours at 215 nits, and 11.97 hours at 178 nits. In our video playback battery test the Venue 10 does very well. Those happen to be the very same tasks the Venue 10 is targeted at with its keyboard attachment, and it's just not acceptable for a tablet of this price. In any case, the web browsing battery life on the Venue 10 is incredibly disappointing, and battery life will be similar in any display bound scenario such as editing text documents. It's also worth noting that both of these results are from the tablet alone, and would be even lower if the keyboard dock was in use. The gap between the Venue 8 and Venue 10 which have the same internal hardware indicates a fairly substantial increase in display power usage, especially given the fact that the Venue 10 has a larger battery. Even the 178 nit result is extremely disappointing, and not at all competitive with other flagship tablets or even Dell's own Venue 8 7000. At 215 nits it lasts for 4 hours and 47 minutes, and dropping to 178 nits extends this by an hour. In our WiFi web test, the Venue 10 falls short of Dell's estimated 7 hours at both brightness levels. The remaining tests were done at 215 nits. The rest of our tests are far less display bound and to show this I ran the video playback test at both brightness levels as well. Our WiFi web browsing test is our most display-bound battery benchmark, and so for it I tested the Venue 10 at both 178 nits and 215 nits. I've had to make a bit of a compromise when testing the Venue 10. This makes it impossible to test it in the exact same manner as all of our other devices. Dell's brightness curve behaves in such a way that there is a point on it where the brightness jumps from 178 nits to 215 nits at 100% APL (100% white), and there are no points in between. Unfortunately, the Venue 10 presents a problem when trying to do this.
The Venue 10 comes with a 7000 mAh (26.6Wh) battery, and Dell rates it for only seven hours of usage, which is noticeably lower than the ten hours that has become something of a standard for tablet battery life.įor our battery tests we normally calibrate all devices to 200 nits. With flagship tablets, users have come to expect that their device will give them ten hours or more of usage on a single charge.
Battery life is obviously one of the most important aspects of a mobile device.
