Stuck on checking laptop battery health

the report saves into whatever folder cmd is sitting in, so if you can't find it, read the path it prints. there's a cycle count in there too on most laptops. rough rule: once full charge is down around 80% of design capacity you'll notice it in daily use, and that's about where it counts as worn.

open cmd and run powercfg /batteryreport - it writes an html file and tells you where. open it and compare design capacity against full charge capacity. that gap is your real answer, and it's more honest than any app. what does yours come out at?
