A charge cycle is one full 100% of your battery’s capacity used — not one plug-in. Apple gives each Mac notebook a maximum cycle count: the number of cycles the battery is engineered to handle while still holding roughly 80% of its original capacity (Apple’s official figures).
Maximum cycle count by model
| Mac notebook era | Apple’s rated max cycles |
|---|---|
| Apple silicon (M1/M2/M3/M4, 2020–present) | 1000 |
| Intel Retina MacBook Pro / Air (2012–2020) | 1000 |
| Unibody MacBook / Pro / Air (2010–2011) | 1000 |
| 2008–2009 models | 500 |
| Earliest models (2006–2008) | 300 |

What the rating actually means
Reaching the maximum cycle count is not a cliff. Apple’s wording: the battery is “designed to retain up to 80% of its original capacity at its maximum cycle count.” So a 1000-cycle Mac at 1000 cycles should still hold about 80% — usable, just with less runtime. Apple recommends considering a battery replacement at that point for best performance.
How to check your cycle count
Hold Option and click the Apple menu → System Information, then select Power under Hardware — your cycle count is under Battery Information. Mac 4 Breakfast shows it live in the menu bar alongside your real capacity, so you don’t have to dig. Wondering whether your number is high for your Mac’s age?
