Lenovo IdeaPad Tablet K1 Review

Battery Life Test

In an attempt to quantitatively measure the Lenovo IdeaPad Tablet K1's battery life in a controlled benchmark environment, we ran a test in which we set up a webpage with a mix of graphics, Flash media and text. The page automatically refreshes every three minutes and we also setup a screen lock utility that keeps the display from sleeping during the test (if the tablet doesn't have this setting already available). Battery life is then measured down to the minute the tablet finally shuts down. The WiFi radio is enabled in this test, to simulate battery life in real-world web browsing over an 802.11n wireless connection.

Untethered Up-Time Measurements

For this test, we set the IdeaPad Tablet K1's display to 50% brightness, which is still plenty bright and easy on the eyes. The K1 was able to last just over 7 hours untethered before it powered down.



As you can see, as far as 10.1 slates go, battery life with the IdeaPad Tablet K1 falls on the upper end of our performance spectrum, showing it to be within striking distance of Acer's Iconia Tab but a full two hours behind the Samsung Galaxy Tab 10.1, which is our top battery life contender.  Regardless, 7 hours+ of untethered uptime is respectable for the Lenovo IdeaPad Tablet K1.
