Battery capacity measures the maximum energy a battery can store, expressed in mAh for phones and Wh for laptops. Battery life is how long a device lasts before recharging, measured in hours. Battery health, shown as a percentage of original capacity, degrades with charge cycles—e.g., Google Pixel 8a retains 80% capacity after 1,000 cycles.
Higher capacity theoretically increases battery life, but real-world performance depends on usage, screen size, temperature, charging efficiency, and hardware. Fast/wireless charging causes 20-30% energy loss due to heat. Apple silicon MacBooks outlast older Intel models due to efficiency.
Companies test battery life using video playback; actual life varies daily. To extend battery life, update OS, lower brightness, close background apps, and monitor power-draining apps. Battery health matters: after 1,000 cycles, a '100%' charge icon reflects reduced capacity.
