Full Definition & Technical Explanation
Battery life mixes Capacity (e.g., 3692 mAh) with efficiency (SoC, display). DeviceBenchmark shows real tests: Web Browsing: 09:21 hr, Watching Video: 19:24 hr, Gaming: 06:44 hr, Standby.
SoCs with high efficiency often outlast larger mAh rivals. Laptops report capacity in watt-hours (Wh).
