Battery capacity, measured in milliampere hours (mAh) or watt hours (Wh), quantifies the maximum energy a battery can store. In contrast, battery life refers to the actual duration a device operates on a single charge, typically measured in hours. While a higher capacity generally suggests longer potential battery life, real-world performance is influenced by numerous factors including device usage, screen size, temperature, and the efficiency of the operating system and hardware. Battery health, a percentage of the battery's original capacity, also degrades over time with charge cycles. AI
