Apple just launched the iPhone 6s and the iPhone 6s Plus last week, and both devices are already available for pre-orders. Most notably, these phones come with new features. iOS 9 software, 3D Touch, a new Apple A9 chip, and a 12 MP camera capable of 4k video recording.
What is a 4K video?
4k videos are videos of very high resolution (3840 x 2160). The catch is that they consume lots of storage space. We discovered this when we played with the OnePlus One.
The least/cheapest model of the iPhone 6s is the 16 GB model, so PhoneArena tried to calculate just how much 4k video an owner of this iPhone can record. We should also note: out of the 16 GB storage, only (approximately) 12 GB is usable.
