TL;DR
Battery cycle count is the number of complete charge-discharge equivalents a device's lithium battery has accumulated, with partial charges summed, so two half discharges equal one cycle. Manufacturers rate design life in these units: phone batteries are engineered to hold about 80 percent capacity at 500 cycles, recent iPhones at 1000, and laptop packs commonly at 1000.
What it means
Battery cycle count is the number of complete charge-discharge equivalents a device's lithium battery has accumulated, with partial charges summed, so two half discharges equal one cycle. Manufacturers rate design life in these units: phone batteries are engineered to hold about 80 percent capacity at 500 cycles, recent iPhones at 1000, and laptop packs commonly at 1000. Repair shops read the value through diagnostic software to separate a worn battery from a power-management fault before recommending replacement. A high reading paired with shrunken full-charge capacity is the objective case for a new battery rather than guesswork about battery health.
