Improved Battery Life
IE11 uses the GPU to process gestures like swiping, panning, and zooming of images. The whole JPEG image-decoding pipeline is also offloaded to the GPU. All these allow the CPU to work on the more important tasks, and also enhance battery life. The browser also allows up to 100 tabs per window, as opposed to just 10 tabs per window in IE10. Powered by SkyDrive, opened tabs, favorites, history, user names, and passwords also stay in sync across multiple devices.
IE11 windows will snap side by side automatically, making working with other apps a breeze.
