Here’s How Many Minutes of 4K Video Your 16GB iPhone 6s Can Shoot

Tech reviewer Marques Brownlee, who attended Apple’s iPhone 6s / 6s Plus launch event in San Francisco earlier this week, managed to get some hands-on time with both devices after the key note. Interestingly, a screen grab from his short video review, captured and shared by BGR, seems to have answered the question of exactly how many minutes of 4K video can one shoot and store on a 16GB iPhone.

While 4K video shooting capability is one of the more impressive camera features in the new iPhone models, it must be kept in mind that all of that high-resolution clarity comes at a high storage price. As you can see form the above screenshot of iPhone’s video preferences page, it states that each minute of 4K video taken at 30 fps will occupy approximately 375 MB of storage, which is actually more than 2x the amount of storage space a video taken at 1080p and 30 fps takes up. Using this info, the source has calculated the length of 4K video that can be shot using a 16B iPhone 6s.

But before we get started, it’s worth highlighting that new iPhone models doesn’t truly come with 16GB of free space right out of the box. Let’s assume that a brand new 16GB iPhone 6s will, in practice, only have about 13GB or storage for users to play around with.

At 375 MB of storage per every minute of footage, we see that 10 minutes of 4K footage would take up 3.75GB, 20 minutes of 4K footage would take up 7.5GB, and 30 minutes of 4K footage would take up 11.25 GB. Calculating to 13GB shows that a 16GB iPhone would deliver approximately 34 minutes and 40 seconds worth of 4K video.

So there you go, a 16GB iPhone 6s can shoot and store just over half an hour of 4K video, provided no third party apps are installed on its roughly 13GB of storage space.

    4K is a waste. 1080p will suffice. Save your storage.

  • Can’t wait to record 4K video, and watch it on my TV in 1080p.

  • Aleks Oniszczak

    I think the problem is that Apple still sells a 16GB iPhone with a straight face. 4K video is not the problem here.

  • FragilityG4

    4K is a waste of time. Unless you’re looking at a big screen two inches away you won’t notice the difference between it 1080 or even 720.

  • Carlos

    You actually can tell the difference. Granted, I deal with that all the time as a contract editor and colourist.

  • FragilityG4

    Yes but most people sit ten feet back from their TV. Science says the human eye can not see the difference from that viewing distance. Obviously people within a graphic field will see the difference and appreciate it, but to the rest of us, it’s a waste of money — Not to mention Blu-Ray is only 1080.

  • Aleks Oniszczak

    If I lean in from my couch, I can start seeing the pixels on my 1080P 55″ TV. If I never get a bigger TV, then sure, I don’t need to record 4K video. But some day I probably will get a bigger TV and so it will have to be 4K or greater unless I start enjoying watching pixels blink. Your children will have TVs the size of their walls – do you want them to roll their eyes every time you want to show them a blocky old “HD” home movie? 😉

  • Carlos

    Very true!!!

    But as Tim said in the keynote, most people consume media from their mobile devices and in that respect, I reckon people CAN tell the difference between 720 and 1080 watch from their phones or tablets. Not that it really matters, tbh.

    We’re just at a very awkward stage in the transition to 4k. Unlike previous transitions (480 > 720 > 1080), 4k is so accessible right now with phones and cameras that can shoot it, editing apps that can cut it and TV’s that can show it, but production houses haven’t really supported it. It’s like they’re waiting for people to adopt it in their homes and people are waiting for them to produce in it before they adopt it which is going to prolong this whole switch.

    Personally, I’m sticking to my 1080 TV until I can really justify the need for a 4K TV. On that note, I can’t recall if Apple announced the new Apple TV to be 4K ready.

  • FragilityG4

    Assuming today’s media will still be compatible ???? Save your money.

  • FragilityG4

    Cable TV can only transmit 1080i max. Until that hurdle is solved I don’t for see it taking off. Sure everyone will have a 4K TV but you’ll still be watching 1080/480 cable and 1080 Blu-Rays. Some will stream 4K Netflix shows (if they have unlimited data) and some will look at their iPhone filmed movies … But at the end of the day at this point it’s not worth it. Just ask all the HD DVD owners (if they still exist)

  • raslucas

    You’re all right. Still selling a 16GB iPhone as the base at the current price point these days is cheeky up-selling. I would think Apple is better than that. I think it’s hard from a business perspective to shy away from it when they look at the money they make from the higher storage models, as long as the sales do not suffer, which they certainly have not. Still. 16GB base models are Android fanboy fodder.

  • raslucas

    Oh, and for 4K video. I don’t see it as necessary being better for watching a movie. Although if it’s a big enough screen of course it matters. I was thinking that if you have a 4K tv and you have a bunch of nice 4K media. If you had a party at your house where people may be standing around the room, the picture would look a lot clearer. I’m talking about silent scenery and the like. You know what I mean.
