Phone Left In A Hot Car? What Heat Does To Your Battery

A parked car's interior can get far hotter than the air outside on a sunny day. Apple says to avoid ambient temperatures above 95°F (35°C), which can permanently damage battery capacity, and that even storing a battery somewhere hot can damage it. A dashboard in July goes way beyond that.

What Heat Does

• Battery wear speeds up. Heat is the biggest cause of lost battery capacity.
• Swelling. Repeated heat can swell a battery, and the screen starts lifting.
• Screen damage. Some displays can show discoloration after extreme heat.

If It Got Hot

1. Don't put it in the fridge or freezer. Condensation can form inside.
2. Let it cool to room temperature in the shade.
3. Don't charge it until it's cool.
4. Check battery health.
5. If the screen is lifting, stop using it. Read Swollen Battery.

Prevent It

Take it with you, use a mount out of direct sun, and don't charge it on the dash in summer.
