Say what a battery cycle is
Read the battery health page and know what the numbers mean.
A cycle is one battery’s worth of power used, whether in an afternoon or across a week.
Two half charges make one cycle. Batteries are rated in cycles, not in years.
Key points
- A cycle is one whole battery’s worth of power, in any number of pieces
- Batteries are rated in cycles, so short top-ups cost nothing extra
What to remember
- Hundreds of cycles after a few years is ordinary.
- A cycle counts power used, not times plugged in.
