Heat, sun and cold weather

Heat and direct sun

• Shade the phone: a small umbrella or a hood over the tripod makes a big difference.
• Take the phone out of its case while recording, so it can lose heat.
• While recording, the screen dims itself after 30 seconds without a touch to save battery and heat. Tap to wake it. Prefer the screen to stay bright? Turn off Dim while recording in Settings.
• A Warm chip on the screen means the phone is getting hot: tracking checks fewer frames to cool down, but the recording quality stays the same.
• Too hot means the phone is close to its limit. Shade it straight away. iPhones can stop the camera if they overheat.

Cold weather

• Batteries drain much faster in the cold, and a cold phone can switch off even with charge left.
• Start with a full battery, and keep the phone in a pocket until just before kick-off.
• Plug into a power bank from the start, not when the battery is already low.
• Charge the gimbal too: cold drains it as well.

A phone paired as the Remote shows the camera phone's battery and heat, so you can check without touching the camera.
