Apple iPad Air 2 Review: Should You Upgrade?
Performance: Battery LIfe & Camera
How are things today? Let's have a look, starting with FaceTime HD camera.
According to Apple, the FaceTime HD lens has a larger f/2.2 aperture that's supposed to let in 81 percent more light, along with an all-new sensor, though it's still a 1.2-megapixel shooter. However, it's capable of taking single-shot HDR photos and burst selfies, and benefits from improved face detection, just like the iPhone 6 models.
While well short of being a specular camera, the FaceTime HD lens is easily sufficient for video conferencing chores, especially on a casual basis with family and friends. In the shots above, you can see how the FaceTime HD camera handles low-light situations (left) compared to a well lit environment (right).
8MP iSight Camera
As far as tricks go, it supports time-lapse video recording, 120 frames per second slo-mo, shooting in burst mode, 43-megapixel panoramic photos, and more. But it's the quality of photos that the iSight camera with an f/2.4 aperture takes that sets the iPad Air 2 apart from its predecessors in the photography department.
Battery Life
In order to make the iPad Air thin enough to hide behind a pencil, Apple had to use a lower capacity battery, dropping down from 42.5Wh to 32.2Wh. And for the iPad Air 2 to be even thinner, Apple again had to sacrifice battery capacity, this time going down to a 27.3Wh battery pack. Despite the shrinkage, Apple claims the same battery life as before:- Up to 10 hours of surfing the web on Wi-Fi, watching video, or listening to music
- Up to 9 hours of surfing the web using cellular data network (Wi-Fi + Cellular model)
The good news is 10.5 hours is still a long time, and even longer than Apple claims. Plus, you have to leave a little bit of wiggle room for margin of error -- there's no "50 percent" setting for the brightness. Instead, you have adjust the brightness slider halfway, and it's possible one or both tests weren't set at exactly the halfway point. However, that's picking nits and still wouldn't account for a full 2-hour discrepancy.
Bottom line -- battery life is still quite good, and of course will vary depending on what you use the iPad Air 2 for. Gaming will tax the battery faster than less stressful tasks, while you can do things like watch movies or listen to music all day long.
