Battery life dropping noticeably

Even if it only has 444 cycles, like all batteries, if the SP7 is stored, but not used, degradation will occur. I don't know when you purchased the SP7, but it was launched in 2019 which is pretty old in terms of computer lifetime. Microsoft is no longer servicing/replacing batteries in the SP7 - https://support.microsoft.com/en-US/surface/hardware-warranty/how-much-does-out-of-warranty-service-cost-for-your-device-or-accessory-united-states shows that the Surface Pro 7+ (the + being a different and newer device) is the oldest device they offer battery replacement service on. A third party shop may be able to replace the battery, but this is not supported by Microsoft.

Run this in powershell as admin:

powercfg /batteryreport

Check Full Charge Capacity. If it's less than <80% of Full Charge Capacity maybe it's time to replace the battery. It's not user replacable so contact Microsoft or other certified repair center.

Hi John,

A battery capacity of 79% after 444 charge cycles is lower than expected, especially if you're only getting around 2 hours of battery life. While cycle count is one factor, battery health is determined more by its remaining capacity and overall condition.

Before replacing the battery, I recommend:

Run a Battery Report (powercfg /batteryreport) and check the Full Charge Capacity versus the Design Capacity.

Install the latest Windows updates, Surface firmware, and drivers.

Check Task Manager for background apps that may be consuming excessive power.

Test battery life using the Recommended power mode and a moderate screen brightness.

If the battery health remains around 79% and your real-world usage is only about 2 hours, it is likely that the battery has significantly degraded. Since the Surface Pro 7 battery is not user-replaceable, the recommended option is to contact Microsoft Support or an authorized Surface service provider to discuss battery replacement or device service.

I hope this helps!
