Samsung ATIV Book 9 Plus Review
Battery Life
The ATIV Book 9 Plus comes with a built-in 55.5WHr battery that is not user replaceable. Although we prefer user-swappable batteries, we recognize this isn’t the trend among ultrabooks. Samsung claims this battery will last up to 7.5 hours using the Mobile Mark 2012 benchmark test. To get a feel for how the battery in the ATIV Book 9 Plus compares to other systems we’ve seen previously, we tested the machine using what could be considered “worst case” and “best case” scenarios in the following two metrics.

Samsung’s ATIV Book 9 Plus lasted for nearly 2.5 hours in our “worst case” test., which was an excellent score in light of competing ultrabooks. To get another feel for how the ATIV Book 9 Plus stacks up, we also ran our standard web browsing test.
Our web browsing test measures the machine's ability to maintain power under light duty use with its Wi-Fi radio on and the display set to 50 percent brightness. This test refreshes a dedicated web page every couple of minutes and the page has a mixture of text, images, and Adobe Flash media. We consider this to be a "best case scenario" and a decent relative gauge for battery life versus competitive products in a given device class.
The ATIV Book 9 Plus lasted for over nine hours in our web browsing test and shows results that are consistent with the Battery Eater Pro test—the ATIV Book 9 Plus came in behind the 2014 Dell XPS 13 and held the second spot in our chart. Keep in mind this is a light-duty test, but the results are still very impressive.
