Lenovo IdeaTab S2110 Tablet Review

Battery Life

Battery life is critical for tablets, particularly for tablets that have keyboards. If you’re thinking about buying a tablet to stand in for your laptop, strong battery life is a must.

To stretch the IdeaTab S2110’s battery life, Lenovo has a backup battery in the Keyboard Dock. Plug the tablet into the Dock, and it immediately taps your backup power. According to Lenovo, the setup boosts the tablet’s 10 hours of normal use to 20 hours.

On its own, the IdeaTab S2110 held out for 8 hours and 13 minutes, which isn't quite long enough to put it in our chart's top five. That's better battery life than the bulk of the tablets we've recently reviewed, though - and that's without the Keyboard Dock's backup battery. When we ran the same test on the S2110 docked, it took the top spot with 12 hours and 56 minutes of usable battery life.
