Apple has finally heard the complaints of the iPhone fanbase and increased the camera resolution of its two latest models, the iPhone 6S and iPhone 6S Plus. Both devices come with a 12mp camera which can capture videos in 4K resolution (3840×2160 pixels).
Awesome, right? Well, not really. What Apple forgot to do is increase their smartphones’ storage capacity. Yes, the new models will come in the same way as their predecessor, the iPhone 6 – 16GB, 64GB and 128GB, with no possibility to expand the memory, evidently.
Let us do the math, at 8 million pixels per frame, 10 minutes of uncompressed 4K video would occupy up to 52GB of storage. Yes, now imagine how much an hour’s worth of 4K footage would take. The answer is a swooping a whooping 320gb of capacity.
Since 4K resolution is four times larger than 1080p resolution, it’s safe to assume that the iPhone 6 and iPhone 6S Plus’ camera will shoot videos which will be roughly four times the size of their predecessors. The iPhone 6’s 1080p camera shoots at 60 fps (frames per second) and an hour’s worth takes up to 12gb of capacity. If we do the math, assuming that Apple will be using the same compression codecs, the 4K video camera of the iPhone 6S will require approximatively 48GB per hour.
The top-tier iPhone’s capacity is of 128GB, that means it will probably handle a couple of hours of 4K footage. But the 16GB and 64GB versions, which are also much less expensive, are doomed to be strangers to the new technology. If we compare the device with the Samsung Galaxy S5 for example, which is also capable of 4K shooting, we will notice that Samsung’s flagship comes with a 128GB internal capacity, as well as with the possibility to expand it with another 128GB, through SD cards. The Korean device is also significantly cheaper than any of the current series of smartphones.
We have to keep in mind that most digital recorders are using compression codecs. But still, 4K videos will take up a lot regardless of how much compression they will endure. A compression algorithm cannot reduce the size of a video significantly, unless it completely butchers the quality, and that will not happen in Apple’s case. It is rather clear that the company didn’t considered this potential drawback when they conceived their latest devices.
Apple is however offering cloud storage through their brand new iCloud Drive service, but for that you will require an Internet connection.
