How to View Battery Cycle Count on a Windows Laptop
For example, if your laptop battery drains from 100 percent to 50 percent, then you charge it back up to 100 percent and let it drop to 50 percent again, that counts as one cycle. Battery cycle count, then, is the number of times that your battery has gone through a cycle. The lower your laptop''s battery cycle count, the "healthier" its battery is.
