Yoga C940 - Extremely Poor Battery Life

2020-12-10, 13:12 PM

I'm get less than 3 hrs, even when Windows 10 Battery Saver is on. Might have something to do with the display as I am unable to adjust the brightness, either through Windows Settings or via keyboard shortcuts. Any ideas?

What is current battery capacity (not design capacity)?

Battery wear level?

Unsure what to try. The battery only charges to 60%. From that level, it only lasts 2 hrs or so. I am unable to get battery info from Lenovo Vantage
