Part 1. Why 4K UHD can't play on iPhone (X/8/Plus)

Even if iPhone X/8/Plus/7/SE/6S Plus/6S Plus has announced to support recording/capturing 4K videos, why 4K UHD Videos yet can't play on iPhone (X/8/Plus)?

Reason 1: No 4K display avaliable

As pixel counts exploding over few years, a number of excellent 4K monitors hit store shelves together with quickly spilled over to TVs and PCs. But speaking to playing 4K videos on iPhone X/8/Plus/7 Plus/7/6S Plus/6S/SE, you should at first realize the following cruel facts:

iPhone Model
iPhone X
iPhone 8/7
iPhone 8 Plus/7 Plus
iPhone 7 Plus
iPhone 6S plus
iPhone 6S
iPhone 6 Plus
iPhone 6
iPhone SE
2436*1125-pixels at 458ppi
1334*750-pixels at 326ppi
1920*1080 pixels at 401ppi
1334*750-pixels at 326ppi
1920*1080 pixels at 401ppi
1334*750-pixels at 326ppi
1920*1080 pixels at 401ppi
1334*750 pixels at 326ppi
1136*640 pixels at 326ppi
4K UHD resolution: 3840*2160 (16:9) or 4096*2160 (17:9)

You see 4K UHD video cannot be directly played on iPhone (X/8/Plus)'s display as above.

Reason 2: The size of 4K UHD video is huge

Normally, the minimum size of a 50 minutes 4K UHD "Game of Throne" videos with resolution of 3840 x 2160 pixels at 60fbs (aspect ratio 16:9, the one of the two resolutions of ultra high definition TV targeted towards consumer TV, 4 times than 1080p) is almost 100G, while iPhone's storage is limited for most users as that means get more additional space for a move around 100.5G at least. That is to say, even if iPhone X/8/Plus/7 Plus does have a 256GB of memory, it can only store 2 true 4K full-length films, without in extra saving pictures and installing apps at all.

Reason 3: Network bandwidth limitataion

Then you may ask if is possible to watch 4K videos on iPhone (X/8/Plus) with YouTube app online without saving huge files to iPhone locally? Theoretically it is OK. But unfortunately, the required bandwidth and network condition are beyond your imagination. Especially, when no Wi-Fi is available, the 3G or 4G consumption will be unbearable, (for the average person).

In the meanwhile, the new iPhone X/8 Plus will house a 3GB of RAM for multithread operation (iPhone 8 features 2GB RAM), while it still can't promise the completed avoidance of crash or flashing back, when playing videos, especially 4K and other UHD videos online. The alternative solution is to watch 4K UHD videos on the existing iPhone or new iPhone X/8/Plus offline!

Reason 4:The file formats of 4K UHD Videos are not compatible

As Apple published, the iPhone video formats supported includes ".m4v", ".mp4", ".mov", and ".avi". If the original 4K videos file format is not under these category, then the player in iPhone can't shoot naturally.

"H.264 video up to 4K, 30 frames per second, High Profile level 4.2 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-?LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format"

Then, is it dead-end?
