Microsoft admits faulty drivers were killing Windows 11 battery life for years
Microsoft has acknowledged that faulty third-party drivers have been draining battery life and affecting performance in Windows 11 for years. The company is implementing stricter evaluation processes for drivers to prevent these issues in the future. This overhaul aims to ensure that drivers are assessed not only for crashes but also for their impact on user experience.
- ▪Faulty drivers prevented laptops from entering low-power hibernation mode, leading to unexpected battery depletion.
- ▪Microsoft will now evaluate drivers based on their power consumption, heat generation, and overall performance impact.
- ▪An automatic rollback feature will be introduced to block problematic drivers from affecting users.
