A few minutes after starting at 7:43pm, it began to beep every few seconds. The recording was stopped and reviewed. There are approximately 10s gap between each file. My guess is that the camera has issue writing to the sd card and gave up after buffering 10sec of output, hence dropping the buffered video content and started writing to new file.
Another recording was started at 8:04pm with a more drastic result, since I had set the bitrate to high rather than the default medium.
Upon reviewing the files from the first run, the same issue is observed.
(Durations 00h08m06 and 00h01m59)
I went to flash the firmware. It was actually downgraded from 2026 to version 2015.
Third Run (different firmware version)
There is no recharge between 2nd and 3rd run. (I remove SDcard from device, rather than connecting the device to the computer via USB). The firmware downgrade erased all my settings so I had to switch on timestamping again. I left bitrate at medium.

Things are much more stable and there are no time gaps between each video. However we need to do a few more runs to ensure this firmware solved the problem.
Total duration for this battery = 00h08m06 + 00h01m59 + 8h11m01 = 8h21m06, including fiddling with settings/sdcard/firmware in-between.
