iPhone 16 39W charging is not fast enough to beat Galaxy S24 Ultra

Apple iPhone 16 reportedly supports faster charging than the iPhone 15 series. The company never discloses charging support in watts on official product sites. Well, the iPhone 16 seemingly supports 39W fast charging, which is still less than the Galaxy S24 Ultra.

According to the info, Apple brought 39W charging support to the iPhone 16 series. Reports are circulating of 45W fast charging functionality. However, practical testing (via IceUniverse) indicates that the max charging speed is 39W.

CQC results suggest that the iPhone 16 features 45W wired charging. This is about 50% faster than the iPhone 15 series, which supports up to 29W charging. Meanwhile, the maximum support is 39W as tested by reliable industry sources.

Samsung continues to bring 45W charging support in select Galaxy devices. The Galaxy S24 Plus, S24 Ultra, and M55 are some of those. It’s not much higher than the 39W but shows Samsung is already ahead of Apple’s boosted charging function.

The newest S24 series is designed with convenience in mind and super fast charging is a key part. To ensure you can make the most of the S24’s rapid charging capability, there are some requirements for that such as compatible adapter and cable.

Packed with a 5000mAh battery, Samsung’s S24 Ultra typically takes around 78 minutes to fully charge from 0% using a 45W charger. Various factors can impact the charging speed and time to get the battery charged 100%.

Next year, Samsung will launch the Galaxy S25 Ultra. Early rumors indicate that there will be no charging upgrade in the Plus and Ultra models. Yet, we expect improvements in that particular aspect through artificial intelligence.
