Why dual-camera recording drains your battery faster

What’s happening

Each camera streams its own video, and the phone combines and compresses both. More work means more power and heat.

Keep going longer

• Record in short clips.
• Lower the resolution or frame rate if you don’t need them.
• Plug in, or use a power bank.
• Take thick cases off in warm weather.
• Keep out of direct sun.

Heat warnings

If the phone gets too hot, it may dim the screen, stop the flash or stop recording to protect itself. Let it cool before continuing.
