Short answer
Apple's video-playback ratings rise from about 17–28 hours on iPhone 13 models to about 22–33 hours on iPhone 16. Pro Max models have always lasted longest. Real life depends on battery health and use.
Apple rates battery life in hours of video playback. These figures are approximate and are rated on a new battery.
Video playback ratings (approximate)
| Model | iPhone 13 series | iPhone 14 series | iPhone 15 series | iPhone 16 series |
|---|---|---|---|---|
| Mini / standard | 17h / 19h | 20h | 20h | 22h |
| Plus | – | 26h | 26h | 27h |
| Pro | 22h | 23h | 23h | 27h |
| Pro Max | 28h | 29h | 29h | 33h |
How to read this
- The mini and standard values in the iPhone 13 column are for iPhone 13 mini and iPhone 13.
- Newer iPhones, including iPhone 17 and 18 Pro, are rated higher still — check Apple's specifications.
- A used iPhone with a worn battery will last much less than these ratings.
Best for battery
For the longest battery life on the used market, look at Pro Max models or Plus models, and always check battery health.
