![]() Apple has fewer graphs built in, but you can see usage statistics in System Preferences > Battery. To see your battery usage graphs over the past 24 hours or 10 days, go to System Preferences and then Battery. There, you can see the cycle count of your battery, its estimated health, and all of your current power settings. To see it, go to the Apple menu in the top left, and click “About This Mac.” Then click the System Report button, and under Hardware, go to Power. If you’re an Apple user who’s feeling left out, don’t worry: macOS lets you access some battery information, too, though there isn’t as much historical data. My laptop is a 2018 model, and I’m pretty sure it’s gone through more than 177 cycles since then.Įven if you’re on a newer install, you can get a general sense of the health by looking at the design capacity and then the full charge capacity to see how different they are. If you’ve just bought a used laptop and want to know what state the battery is in, you’ll probably want to run this tool before wiping Windows, as it seems the cycle count only reflects what’s happened on the current Windows install. One caveat: my laptop is used, and as a policy, I completely nuke whatever Windows install is on any laptop I buy, overwriting it with a new one. Seeing the design capacity estimate versus your actual time could tell you whether it’s time to replace your battery. This could help you get an idea of how you use your battery or show your recent computer habits. The battery usage graph can tell you how fast your battery drains over time. Now you can see all of that sweet, sweet battery information. The battery report will be an HTML file that’s stored in a folder on your PC. At the command prompt, type powercfg /batteryreport, then press Enter.
