troubleshooting battery
Hello, my inspiron15 battery is draining quickly these days. I have a battery report (made via cmd and powercfg command). Can someone help me troubleshoot? What should I look at?
Many thanks.

Divide the current charge capacity by the design capacity -- multiply by 100. This is the percentage of the original battery capacity that remains.

Thanks. I have full-charge 30,472 mWh vs. design 41,998 mWh, so 27% wear, should I replace the battery?

If the current runtime is insufficient, yes. A new battery should improve runtimes by 30%.
