How long can you record on iPhone 7 plus in slow mo

Welcome to iMore!.

Thats a tough question to ask since there are many size configurations and frame rates:
iPhone (32GB / 128GB / 256GB)
Slow Mo frame rates (120 fps / 240 fps)

A 1080p (30 fps) with 1 minute in duration requires 130 MB
A 4K video (30 fps) with 1 minute in duration requires 375 MB

1080p resolution at 120 fps uses approximately 375 MB per minute
720p resolution at 240 fps uses approximately 300 MB per minute

Hope this helps you out!
