In an attempt to quantitatively measure the Latitude 10's battery life in a controlled benchmark environment, we ran both Battery Eater Pro and our own Hot Hardware web browsing test where we set up a webpage with a mix of graphics, Flash media and text. The page automatically refreshes every three minutes, we loop the page and disable sleep and hibernate modes. Battery life is measured down to the minute the tablet shuts down. The Wi-Fi radio is enabled in this test to simulate battery life in real-world web browsing over a wireless connection. The stock browser was used. For both tests, we set the Latitude 10's display to 50% brightness, which is still plenty bright and easy on the eyes.
When using the optional extended-life 4-cell battery, the Latitude 10 boasted of the longest battery life in comparison to all other devices we’ve tested; the Latitude 10 lasted over 18 hours in our Hot Hardware web browsing test. Using the stock 2-cell battery, the Latitude 10 took fourth place just behind the Acer Iconia W510 tablet.
The story is much the same in the Battery Eater tests: Dell’s Latitude 10 earned the top spot by a comfortable margin when using the optional extended-life 4-cell battery. When using the stock 2-cell battery, the Latitude 10 again took fourth place however this time it outlasted the Iconia W510 by a small margin.
