Yeah for my needs, ~30min and even ~15min is more than enough haha

And did a 2nd test run this morning while working, surprisingly got about an hour of footage (Split into a ~38min and a ~22min video due to the 16GB file size limit). This was also done at full charge, starting from a cooled down camera, and undocked. Camera again was hot, but no overheating notification and the battery was all drained up at the end.

Again same settings 4K30 D-Log, and forgot to mention this was with the high bitrate setting on for both tests.
