@kilee I had the same problem as you in every video mode. 1080/60 or 4k sometimes it would record 8 minutes, other times 2 or 3 minutes. It would heat up pretty fast. I swapped to a new nano sim, tried a lot of sdcards on which I did low level format and a bunch of benchmarks and other stuff, tried to record to the internal and external memory, checked the ambient temperature and also let the phone on idle for a long time and checked its temperatures to no avail. Sometimes it would perform so and so and others a total let down. I sent it back, the store personal inspected and tested the phone and a few days later gave me a new one. With the replacement I'm really happy, except for some details on both camera's assembly and lens, but I have achieved at least 3 times recording 4k for 23-25 minutes. Air temperature at this time of the year here is in between 16-21. I even did a video playing drums with all options of the camera on... 1080/60 and 4 K recording times fine here.
Probably it could be a hardware issue. I would try contact the place from whom you bought to see what can be done.
@Sailor Where do you save the video? If it's an external microSD, make sure it's a fast one.
During the weekend, I took several videos and it was possible to record landscape around 10 minutes more.
But, when I took the video for my family(persons), it runs about 5 minutes or less.
I`m sure that this issue related to the face tracking.
Even I have been using Sony microSD card to support U3(MLC/R:95MB/W:90MB), I also tried to record the video to internal storage but the result was same.
