Lenovo ThinkPad X100e Ultraportable Review

Power Consumption and Battery Life



A few things are most important to business users: portability, rigidity, connectivity, usability and battery life. While the ThinkPad X100e excels in most of those areas, it falls short in the last department. Battery life is definitely not the X100e's strong suit, as we were only able to eke out just over two hours of usage in our real-world battery test. We left screen brightness at 65%, Wi-Fi on and all other apps closed.



We're beginning to really understand why Lenovo bundled a 6-cell battery in with this machine, even though it protrudes from the rear. A 4-cell battery would've sat flush, but the battery life would have been extreme low. As it stands, 2 hours and 11 minutes isn't the worst, but it's not fantastic; most other ultraportables can get far more life out of a single charge, and while it's nice that you can carry around a spare battery if you need it, we wanted to see at least 3 hours here.

If you used the machine lightly and disabled Wi-Fi, you may be able to get 3 or 3.5 hours from a single charge, but we wouldn't bank on seeing more than that. We also noticed a good bit of heat during usage, so it's clear that something (likely the relatively powerful Athlon Neo CPU) is really cranking through some energy.
