iPhone 16 Pro Max’s maximum sustained charging speeds are around 30W

iPhone 16 Pro and iPhone 16 Pro Max feature a 48MP Fusion camera, a 48MP Ultra Wide camera, and the 5x Telephoto camera, now available on both models.
While a Chinese regulatory filing showed that all iPhone 16 models are rated for up to 45W charging speeds, tests have since shown that the devices do not actually charge this quickly. However, there do seem to be improvements over previous iPhones.

ChargerLAB last week tested the iPhone 16 Pro Max with a variety of Apple and third-party chargers, and it found that the device achieved maximum sustained charging speeds of around 30W.
In one image, the website showed the iPhone 16 Pro Max reaching a peak charging speed of 37W with Apple’s 140W USB-C power adapter, but it is unclear how long the device kept charging at that speed. Overall, this seems to be an improvement over the reported 27W peak charging speed for iPhone 15 Pro models, but it is clear that iPhone 16 models are not actually reaching the theoretical 45W ceiling that was rumored.
Apple merely says that all iPhone 16 models can achieve up to a 50% charge in around 30 minutes with a 20W or higher USB-C charger, which is exactly the same claim that it advertised for all iPhone 15 models.

MacDailyNews Note: You can fast charge your iPhone 8 or later up to 50 percent battery in around 30 minutes.
To fast charge, you need an iPhone 16 or later with a USB-C cable, like the one that came in the box, or an earlier iPhone model with a USB-C to Lightning cable and one of these adapters:
• Apple 18W or greater USB-C Power Adapter (You need a 20W or higher power adapter to fast charge your iPhone 12 and later)
• A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)
To wirelessly fast charge, you need an iPhone 16 or later with a MagSafe Charger and one of these adapters:
• Apple 30W or greater USB-C Power Adapter
• A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)
For iPhone 15 and earlier, you can fast charge up to 15W with a MagSafe Charger and one of these adapters:
• Apple 20W or greater USB-C Power Adapter
• A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)
Remember: Fast charging might not work in conditions that are too cold or too hot.
If you’re not sure which Apple Power Adapter you have, check the wattage on the top or bottom of the adapter.
