Most MacBook owners don't check their battery health until something goes wrong. CleanMachine shows your health %, cycle count, temperature, and charging status — plus five evidence-based tips to extend your battery's life. Free to check, always.
macOS 13+ · Apple Silicon & Intel MacBooks · Desktop Macs show "No Battery"
Battery health percentage measures your battery's current maximum charge capacity compared to its original design capacity. A brand-new battery is 100%. After years of use, the maximum capacity decreases — a battery at 80% health can only hold 80% of its original charge.
CleanMachine reads the raw capacity data from the AppleSmartBattery IOKit entry:
Health % = (AppleRawMaxCapacity / DesignCapacity) × 100, capped at 100%.
A battery cycle is defined as using 100% of your battery's capacity — but it doesn't have to happen in one session. Going from 100% to 50%, then charging back to 100%, then going to 50% again counts as one full cycle.
Apple's rated cycle life for MacBook batteries:
CleanMachine shows your cycle count alongside your battery's rated cycle life, so you know what percentage of the battery's designed lifetime you've used.
These are from Apple's own battery care documentation and lithium-ion chemistry research:
Health %, cycle count vs. rated life, temperature, charge status, and Optimized Charging detection. Coaching tips included. Free in CleanMachine.
Detects thermal state and CPU throttling without requiring admin. Shows if your Mac is actively throttling performance to protect thermals.
Live RAM usage breakdown: wired, active, inactive, compressed, free. Purge inactive memory without restarting when memory pressure is high.
Composite health score across storage, cleanliness, performance, memory, and security. A quick read on your Mac's overall condition.

No. Battery health below 100% is completely normal, even on a fairly new Mac. Any reading above 80% is considered normal by Apple. Start paying attention when it dips below 80% — that's when you may notice noticeably shorter battery life.
Not currently. Limiting the charge cap requires writing to the SMC (System Management Controller), which requires a privileged helper — significant complexity and security surface. CleanMachine includes the Optimized Battery Charging detection and a direct link to enable it in System Settings, which achieves similar longevity benefits through Apple's native mechanism.
CleanMachine gracefully shows "No Battery" on desktop Macs without a battery. All other features work normally on desktop Macs.
