Giving battery life figures for any modern notebook will always be a difficult task due to the huge dynamic range of the mobile platforms used in notebooks today. Take the Samsung 900X1B I’m testing at the moment. It’s not an Ultrabook but it’s built on the same platform to the same dimensions and it will run at anything between 2.8W drain and over 10X that figure. In this article I’ll give you some results from some fairly detailed testing I completed today. In summary, the Samsung 900X1B has excellent battery life for the size, weight and battery capacity. It’s efficient.
The Samsung 900X1B runs on a Intel Core i3 2357M platform. It has a nominal 1.3Ghz clock speed but can speed-step down to 800Mhz. There’s an Intel HD3000 graphics unit, a video encode/decode unit and, of course, lots of busses, components and connectivity. There’s also a 11.6″ 1366×768 screen with a relatively powerful back-light. The battery capacity is 42Wh [I recently corrected our database which showed in incorrect 40Wh.]
The tests I did today were aimed at finding how low the platform can idle and what sort of drain you can expect some of the components to add, all the way up to maximum power usage.
