The iPhone 15 and iPhone 15 Pro models have the potential for peak charging speeds of up to 27W when used with a compatible USB-C power adapter, as reported by the Japanese blog Mac Otakara. While the source of this information remains uncertain, it appears to validate that the iPhone 15 Pro models share the same maximum charging speeds as their predecessors, the iPhone 14 Pro models.
For iPhone 15 core models or superiors Apple recommends using a 20W or higher adapter which will ensure you a 50% charge within half an hour, in fact the same way its predecessor iPhone 14. If the power transfer remains constant throughout the charging process, then you need to wait for an hour for a full charge.
Contrary to previous reports in August, which suggested that some iPhone 15 models could support charging speeds of up to 35W, it now seems that this rumor was inaccurate, as the specs sheets do not highlight these changes.
Here is a breakdown of how iPhone flagship models fare in comparison to Android devices:
| Smartphone | Peak Charging Power | 0-50% charge time |
| iPhone 15 | ~20W (expected) | 30 minutes |
| iPhone 15 Pro Max | ~27W (expected) | ~25 minutes (expected). 30 minutes with 20W adapter |
| Galaxy S23 Ultra | 45W | 17 minutes |
| Motorola. Edge 40 Pro | 125W | 10 minutes |
| OnePlus 11 | 100W | 10 minutes |
| Pixel 7 | 21W | 30 minutes |
ChargerLAB, a website, determined last year that Apple’s 30W USB-C power adapter was the most affordable option capable of charging the iPhone 14 Pro models at their maximum speeds of up to 27W. It is likely that this will remain the case for the iPhone 15 Pro models, with the adapter priced at $39 on Apple’s online store in the U.S.

While real-world tests are still pending, it appears that the 35W charging rumor was inaccurate. All four new iPhone 15 models are set to launch on Friday, September 22.
