Microsoft admits faulty drivers were killing Windows 11 battery life for years

Microsoft has acknowledged that faulty third-party drivers have been causing significant battery drain and performance issues in Windows 11 and older versions for years. PCWorld reports that problematic drivers prevented laptops from entering low-power hibernation mode, leading to unexpected battery depletion during standby. Microsoft is implementing stricter driver evaluation processes that will assess power consumption, heat generation, and performance impact, with automatic rollback capabilities to block problematic drivers. It sucks when a failing battery or a slow PC lets you down at crucial moments--and Windows 11 in particular has repeatedly struggled with such issues. Microsoft now officially acknowledges that these problems appear to be linked to faulty drivers.
