Wired Fast Charging (USB-C)

Performance:

• 0% to 50% in approximately 20 minutes
• Full charge in about 1.5–2 hours

To achieve maximum speed, use any USB-C adapter rated 40W or higher. A 45W or 65W USB-C charger works perfectly.

Qi2 chargers use MagSafe-style magnetic alignment. Quality Qi2 chargers can match MagSafe speeds, though results vary by manufacturer.

Standard Qi Wireless Charging

Older wireless chargers still work but charge significantly slower.

Heat During Charging

The iPhone 17 Pro Max features vapor chamber cooling that helps manage heat during fast charging. Some warmth is normal. If the phone gets too warm, charging slows temporarily to protect battery health.
