Qi2: The Wireless Charging Standard Matures
Qi2 based on Apple's MagSafe technology promises 15W wireless charging with magnetic alignment for all phones. We tested 12 Qi2-certified chargers to measure actual charging speeds, temperature rise, and charging efficiency across different phone models.
Testing Protocol
Each charger was tested with an iPhone 17 Pro, Samsung Galaxy S26, and Google Pixel 10 Pro. We measured time from 20% to 80%, peak phone temperature during charging, charger surface temperature, and charging efficiency.
