A fresh rumor says the iPhone 14 series will support 30W fast charging, which is a significant upgrade from the iPhone 13 series’ 20W rating.

Reports claim that an unknown charger manufacturer is providing 30W iPhone 14 adapters to the press in exchange for early access and reviews, giving credence to the rumor. This organization believes that Apple will promote 30W charging as a feature of the iPhone 14 series.
This is not entirely out of the question, even though there is no visual or reference to support this leak. For a limited time during testing, the iPhone 13 Pro Max supported 27W charging, suggesting that 30W support is possible.

For now, an iPhone 8 or later plugged into an 18W PD USB-C wall converter will charge up to 50% power for 30 minutes. Fast charging at 20W is supported by the iPhone 12, and later generations.

This time can be drastically reduced with the 30W charger, but the extra heat generated will be quite uncomfortable. More power means faster charging times, especially for a small battery like the iPhone. However, this leads to higher temperatures, lower efficiency, and faster battery discharge.

It’s unclear whether 30W charging will be exclusive to the iPhone 14 Pro versions. One such limiting factor may be battery size, with only “max” models eligible for this feature.
Two 35W Dual USB-C Port Power Adapters were produced by Apple not too long ago, allowing users to charge their MacBook Air and iPhone at the same time.

These chargers were previously thought to be an expected 30W charger arriving in 2022, but this new rumor suggests that Apple may be working on another GaN charger. On September 7, Apple is rumored to have held an event where they would reveal the iPhone 14 lineup.
Twitter user DuanRui, who has a checkered past, leaked the information. His information comes from the Chinese supply chain and is widely shared on the popular Chinese microblogging service Weibo.
