The iPhone 15 has a 48 MP main camera. Photos taken in high-resolution mode are bigger than 12 MP ones (about 5 MB each in HEIC), so a library fills faster than on older iPhones. The smallest version has 128 GB. It lasts a while, but a few years of video fill it.
How much fits on the iPhone 15
Capacity of each version if it held only that type of file. Typical High Efficiency sizes; the real mix on your iPhone is different.
| Storage | 4K video, 30 fps | 4K video, 60 fps | 1080p video, 30 fps | Photos (12 MP) |
|---|---|---|---|---|
| 128 GB | 12.5 h | 5.3 h | 35.6 h | 64,000 |
| 256 GB | 25.1 h | 10.7 h | 71.1 h | 128,000 |
| 512 GB | 50.2 h | 21.3 h | 142.2 h | 256,000 |
iOS and its apps take part of the capacity, so the space you can fill is smaller than the number printed on the box.
What usually fills the iPhone 15
- Videos. A 10-minute 4K 60 fps clip is around 4 GB, so a few long recordings weigh more than thousands of photos.
- Similar shots and copies. Bursts, retakes and the same photo saved twice add up quietly.
- Old screenshots and Live Photos. Small one by one, but years of them take real space.
- Messages, apps and their data. Check Settings › General › iPhone Storage to see how much each one holds.
