Further to the main review…
I’ve just recorded video in 170deg, 1080p, at 30fps and drained the battery from fully charged. There was 2 hours 52 minutes of video recorded. So, aligns with the “nearly 3 hours of battery” from Drift.
Interestingly, it records in 30 minute chunks. As each 30 minutes is reached, it closes that file and opens the next in the numbered sequence. Probably not a bad idea – rather than having 1 massive file to download at the end of a day’s riding.
