 Battery life
Surface Pro X: Up to 15 hours of battery life based on typical Surface device usage. Testing conducted by Microsoft in September 2020 (Surface Pro X with Microsoft SQ® 1 and Surface Pro X with Microsoft SQ® 2) using preproduction software and preproduction configurations of Surface Pro X. Testing consisted of full battery discharge with a mixture of active use and modern standby. The active use portion consists of (1) a web browsing test accessing 8 popular websites over multiple open tabs, (2) a productivity test utilising Microsoft Word, PowerPoint, Excel and Outlook, and (3) a portion of time with the device in use with idle applications. Tested with Windows Version 10.0.19041.1(20H1) and Edge version 85.0.564.51. All settings were default except screen brightness was set to 150nits with Auto-Brightness disabled. Wi-Fi was connected to a network. Battery life varies significantly with settings, usage and other factors.
