Battery
Battery Health
How much capacity a battery keeps over its lifetime; rated in charge cycles.
Also known as:
Battery Cycles
Charge Cycles
1000 cycles
Battery degradation
Full Definition & Technical Explanation
Battery health declines with use. Manufacturers rate batteries in cycles — e.g., Battery cycles: 1000 cycles (~80% capacity retained). See Battery cycles in specs.
Slow charging and avoiding full discharges/deep heat slow degradation. Modern phones expose a "Battery Health" % in settings.
