Microsoft has recently released a firmware update for the Microsoft Surface Pro 11 and Microsoft Surface Laptop 7, both equipped with Qualcomm Snapdragon ARM processors, introducing the same charging limit functionality previously available on Intel-based Surface devices.
Once updated to the latest firmware, users can configure charging limits directly within the Surface app—such as capping the battery at 80%—so charging automatically stops upon reaching this threshold, thereby extending battery lifespan.
This new feature, named Smart Charging, offers three customizable options: Adaptive Charging, an 80% charging limit, and a 100% charging limit. The 80% cap is a newly added option from Microsoft. Smart Charging is particularly valuable for those who frequently keep their devices plugged in, as it mitigates the long-term degradation caused by repeatedly charging to full capacity, which can shorten battery life and reduce endurance over time.
Previously, Surface UEFI settings did offer a charging limit, but only at an impractical 50% cap. The industry standard has long been 80%, and with this update, users no longer need to enter the UEFI menu to configure it.
Microsoft began developing Smart Charging in May, initially rolling it out to Intel-powered 12-inch Surface Pro and 13-inch Surface Laptop models. Now, Snapdragon-powered devices can also benefit from this functionality.
Firmware Update Release Notes:
- Security: Resolved vulnerabilities that could leave the system in an insecure state.
- Reliability: Fixed issues causing unexpected shutdowns after updates, as well as shutdowns related to display output.
- Usability: Corrected potential backlight flickering when using the device at the lowest brightness level.
- Usability: Enabled the new charging feature via the Surface app, allowing charging to stop at 80% to prolong battery life and offer greater flexibility.
Users of these devices can check for firmware updates via the Settings menu. The installation process may take some time, and while firmware updates generally complete without issue, it is strongly recommended to back up important data beforehand to avoid potential complications that could render the device inaccessible.
