I want to use my iPhone XS Max to film my son's wedding mass, which will run about 75 minutes. Two questions:

Use 3 devices. Two of them at different locations around the room and one down the middle.

1) It depends on the resolution you shoot the video in. For a 75 minute video i strongly recommend capturing in either 720p,. 1080p 30 fps or 60 fps. You can change your resolution in Settings --> Camera --> Record Video. With 1080p it's likely in the 5 - 10 GB range.
2) It should last 75 minutes no problem. You can also turn the brightness completely down since you won't need the display as soon after you start to record. That will also save battery.
