- iPhone 17 Pro Max charges 0→50% in ~38m with 40W, ~20m optimally (47% faster).
- iPhone 17 Pro charges 0→50% in ~31m with 40W, ~20m optimally (35% faster).
- iPhone 17 charges 0→50% in ~28m with ~27W, ~20m optimally (29% faster).
- iPhone 17e and Air cap at 20W—no speed gain with higher-wattage chargers.
- iPad Pro 13" M4 charges 0→50% in ~1h 30m with stock 20W, ~45m optimally (50% faster).
- iPad Air 13" M4 charges 0→50% in ~1h 25m with stock 20W, ~55m optimally (35% faster).
- MacBook Air 15" M5 charges 0→50% in ~52m with stock 40W, ~30m optimally (42% faster).
- MacBook Neo ships with 20W charger but supports 30W—biggest gap in laptop lineup.
- Battery lifespan doubles for every 10% reduction in max charge (e.g., 80% charge → 4× lifespan).
- iPhone 15+/MacBooks last 1,000 cycles to 80%; iPhone 14 and earlier last 500 cycles.
- 140W multi-port chargers split power dynamically (e.g., 100W + 60W in two-port mode).
- Apple’s old 5W USB-A charger is still in use but extremely slow for modern devices.
