We test Surface devices so we can provide you with an estimate of how much battery life you might expect from your Surface device. For some products, testing is also conducted according to carrier specifications. The actual amount of battery life you experience can vary significantly and depends on which Surface device you have, how you use it, network and feature configuration, signal strength, and settings and other factors. In addition, users of Surface devices with lithium-ion batteries will also experience changes in battery life over time. Like all batteries, lithium-ion cells are consumables that age and deteriorate over time and with usage. For more information on battery care, see Caring for your Surface battery.

We currently use battery life test models that reflect activities typical to a Surface user. For some of our older devices, we used a local video playback battery life test.  Details for the testing can be found below by Surface device.
