The iPhone 16 Pro and iPhone 16 Pro Max will reportedly have much faster charging speeds. According to ITHome, the iPhone 16 Pro will support 20W charging with MagSafe and 40W wired fast charging.
Current Charging Speeds
All four iPhone 15 models currently support wired fast charging speeds of 27 watts with a compatible power adapter. This allows you to charge your iPhone up to 50% battery in around 30 minutes. MagSafe charging speeds max out at 15W for the iPhone 15.
Notable Increase in Charging Speeds
If this week’s rumor is true, it’s a significant increase in charging speeds, especially for wired fast charging. However, the report also mentions that the iPhone 16 Pro models will have larger batteries than the iPhone 15 lineup, which will offset the increase in charging speeds.
Battery Capacities Comparison
Here are the battery capacities of the iPhone 15 lineup:
- iPhone 15: 3,349 mAh
- iPhone 15 Plus: 4,383 mAh
- iPhone 15 Pro: 3,274 mAh
- iPhone 15 Pro Max: 4,422 mAh
And here are the rumored capacities for the iPhone 16:
- iPhone 16: 3,561 mAh (up 6.3%)
- iPhone 16 Plus: 4,006 mAh (down 8.6%)
- iPhone 16 Pro: 3,355 mAh (up 2.5%)
- iPhone 16 Pro Max: 4,676 mAh (up 5.7%)
Energy Density and Battery Replacement
Apple analyst Ming-Chi Kuo has reported that the iPhone 16 battery will have greater energy density. Apple is also testing ways to make the iPhone 16 battery easier to replace, thanks to a new metal casing on the battery.
How to Fast Charge Your iPhone
To fast charge your iPhone 15 (or any iPhone since the iPhone 8), you need a USB-C cable or a USB-C to Lightning cable, and one of these adapters:
- Apple 18W, 20W, 29W, 30W, 35W, 61W, 67W, 87W, 96W, or 140W 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)
Personal Recommendations
My personal favorite from Apple is its 35W dual USB-C port, which features a compact design. I also like Satechi’s multi-port wall plugs.
