I've managed a very respectable 16 minutes and 36 seconds of 4K at 30fps with my Lumia 930 before getting the overheating message and having the recording stopped by the system..
I was planning to buy either a S6 or a G4, but after I saw that both models are limited to 5 minutes of rec time, I gave it up.
The most amazing thing about the Lumia is that even after the overheat message the phone was merely warm. I've definitely seen it a lot warmer than that.
Interesting facts:
The video file is not split after a certain amount of data (file system bounded), like in most camcorders out there.
The file size was 6.84 GiB. If you have an empty phone before starting, that means you can record almost an hour of footage in 4K. If you choose 24fps, that figure will increase, as the bitrate is set to a lower value (58 Mbps versus 45 Mbps). When it comes to video bitrate, stock vs. stock, a Lumia 930 beat every single phone out there, I guess.
The battery charge level dropped from 97 to 79% during the process, with maximum screen brightness (daylight), so we're looking at an approximate figure of 1.1% of battery juice per minute (considering a linear decrease rate).
That way, one can expect to run out of memory before running out of battery.
I haven't recorded another file in sequence, so I can't tell if it could keep on recording the same amount right after the first file.
I am planning to upload the video to my youtube page, but my connection is just crap, so it could take a time.
Conclusions:
I guess that makes Lumia phones better options when it comes to video recording than all current Android devices out there.
I just wish Microsoft could implement some additional controls for videos, like:
Contrast
Saturation
Noise suppression
Sharpness
Bitrate levels for both video and audio (something like 100Mbps for video and LPCM recording for audio).
These would help producing truly amazing videos with these phones.
Any developer out there knows whether these controls can be implemented in a dedicated third party app?
