Thanks to its high-quality camera and great apps for editing video and adding effects, the iPhone is a mobile-video powerhouse (so much so that some feature films have even been shot on them). But what good is all that power if you can't store the video? The question that iPhone owners who shoot a lot of videos have to ask is how much video can you record on the iPhone?

The answer isn't completely straightforward.

Many factors influence the answer, such as how much storage your device has, how much other data you have which determines how much storage space you have available, and what resolution video you're shooting. To figure out the answer, let's take a look at those issues.

How Much Available Storage Users Have 

Obviously, the number one factor in how much video you can record is how much space you have available to record that video into. If you have 100 MB of storage free, that's your limit. It's impossible for me to say precisely how much storage space any given user has available without seeing their device, and so it's impossible for me to tell you exactly how much video you can shoot.  But we can make some reasonable assumptions and work from them.

Let's assume that the average user is using 10 GB of storage on their iPhone (this is probably low, but it's a good, round number that makes the math easy).

This includes the iOS, their apps, music, photos, etc. On a 16 GB iPhone, this leaves them 6 GB of available storage to record video into; on a 128 GB iPhone, it leaves them 118 GB.

Finding Your Available Storage Capacity

To find out how much free space you have on your iPhone, follow these steps:

  1. Tap Settings
  2. Tap General
  3. Tap About
  4. Look for the Available line. This shows how much unused space you have to store the video you record.

How Much Space Each Kind of Video Takes Up

To know how much video you can record, you also need to know how much space a video is going to take up. The iPhone's camera can shoot video in different resolutions, resulting in videos of different quality. Lower resolution leads to a smaller file.

Modern iPhones can all take video at 720p and 1080p HD, while the iPhone 6 series adds 1080p HD at 60 frames/second, and the iPhone 6S series adds 4K HD.

According to Apple, this is how much storage space video at each of these resolutions takes up (figures are rounded):

How Much Video An iPhone Can Store

Here's where we get down figuring out how much video iPhones can store.

Assuming that each device has 10 GB of other data on it, here's how much each storage capacity option of the iPhone can store for each kind of video. The figures here have been rounded to the closest minute.
