Camera and Battery Life
Lenovo improved the rear-facing 8 megapixel camera from previous models by incorporating an f/2.2 wide aperture lens, which is better for darker environments. The camera also has blue calcium oxide glass to (reportedly) give images more life-like colors and to help reduce glare.
In the camera controls, you’ll find options to change the resolution, select a scene mode, adjust various effects, and much more. Scene modes include Auto, Portrait, Landscape, and Sports. In the Effect menu, you can adjust the exposure, brightness, contrast, saturation and sharpness. In the final control menu, you can adjust the white balance, anti-banding, enable GPS, change the focus mode, and more.
During our tests with the Yoga Tablet 2 Pro, images taken with the rear-facing camera were acceptable. The camera did a good job at focusing quickly, and you can touch the screen to adjust the focal point. Holding the Yoga Tablet 2 Pro to try to take a picture with the rear-facing camera was very awkward since the tablet is so large and the camera is located near the base of the back of the tablet. Here are a few sample pictures:
Lenovo designs its YOGA tablets around the cylindrical battery that also serves as a handle for the tablet and provides space for the speakers and projector. According to Lenovo, the fixed 9600mAh Li-ion battery in the Yoga Tablet 2 Pro should last for up to 8 hours of Wi-Fi browsing and over 5 hours of projector usage.
In an attempt to quantitatively measure the Yoga Tablet 2 Pro's battery life in a controlled benchmark environment, we ran our own HotHardware Web browsing test where we set up a webpage with a mix of graphics, media, and text. The page automatically refreshes every few minutes. This is a simple baseline test that measures up time while browsing the web. For this test, we set the Yoga Tablet 2 Pro's display to 50% brightness and connected to the web via a wireless network. In this test, the Yoga Tablet 2 Pro lasted for nearly 7.5 hours which is close to Lenovo’s claims but not quite as long.
We also ran the latest version of the AnTuTu battery test, which is available on the Play Store. Because the new version is not compatible with the old version, we aren’t able to use the comparison numbers from previous tablet reviews to see how the Yoga Tablet 2 Pro compares. The test reported a score of 7243, which was very good in AnTuTu’s in-app comparison chart.
Compared to other tablets we’ve previously reviewed, the Yoga Tablet 2 Pro doesn’t have the same longevity in our HotHardware battery test, but it’s important to keep in mind the other devices also have smaller screens. Of course, battery life can vary considerably depending on how the tablet is used.
