Samsung's Galaxy S9 and S9 may have the most advanced smartphone camera ever made, but the iPhone X's camera beats it in one big way. 。

Prospective Galaxy S9 users might be disappointed to learn the new flagship Android phone can't record video in 4K resolution at the highest (read: smoothest) 60 frames per second frame rate as long as the iPhone X can. 。

A video uploaded to Reddit has revealed the Galaxy S9 and S9 only records 4K video at 60 fps for a maximum length of five minutes.。

That may not seem like a deal-breaker (seriously, maybe it's not), but it's somewhat disappointing when you compare it to the iPhone. 。

On the iPhone 8, 8 Plus, and X, you can record videos in 4K resolution at 60 fps for as long as you want — so long as you have enough storage.。

There are various reasons why Samsung might be limiting the S9's full video recording capabilities. When you record high-resolution video at higher frame rates, the camera captures and writes more data to the storage. As a result, recording in 4K60 usually taxes the system-on-a-chip (SoC), which contains the processor and graphics chip and more, and leads to overheating. 。

New users may be surprised to hear this limitation, but it's not really shocking if you've ever used a Samsung or Android phone before with a Qualcomm chipset.。

For its flagships, Samsung typically sells two versions: one with a Qualcomm Snapdragon chip and one with its own-designed Exynos chip. It would appear that Samsung phones with Snapdragon chips have long had a limit for their video recording.。

For example, a Galaxy S7 with a Snapdragon 820 chip could only record full HD video at 60 fps for a maximum of 10 minutes, whereas there was no such limitation on a Galaxy S7 with an Exynos 8890 chip. 。

Why's there a difference? Simple: hardware architecture. Samsung phones with Exynos chips seem to be less prone to overheating and therefore can withstand longer recording times. We've also reached out to Samsung for a more detailed explanation on why 4K60 capture is limited to five minutes and will update this story if we receive a response. 。

Apple, on the other hand, doesn't need to worry about these problems because it designs its own more power-efficient silicon for its iPhones. In other words: Apple's vertically-integrated hardware and iOS are more capable than lumping together a bunch of off-the-shelf components with Android.。
