Compared to competing devices, the battery in the TabPro is pretty typical. The Surface Pro 4, for example, packs a 38.2 Wh battery and a processor that consumes more energy. The 12.9-inch iPad Pro targets a slightly different market, but it packs a 38.8 Wh battery which again is similar in size. In general, the battery life exhibited by the TabPro S is very good. I was able to get a solid day’s worth of usage out of the device, which mostly included web browsing and document editing over Wi-Fi on a moderate brightness level. I wasn’t able to achieve Samsung’s claimed 10.5 hours in any sort of reasonable productivity use cases, and I achieved better battery life from my Surface Book, but the TabPro S did not disappoint in this department
