It hasn't been an issue so far. I have recorded well over an hour at a time and had plenty of space left on the device. I haven't tried leaving it recording overnight (since the birds are in torpor then anyway). That particular phone was 64GB, which can hold something like ~4 hours of 1080p30 video.

The phone contains no apps other than the pre-installed ones, and no data other than the video I'm capturing. After moving the videos to my computer, I remove them from the phone.
