Apple only highlighted the inclusion of Qi wireless charging on the iPhone 8 and iPhone X at its launch event yesterday. However, an unarguably more useful feature on these handsets is the inclusion of fast charging. Apple had quietly shown a slide during the launch presentation mentioning support for fast charging on the iPhone X and iPhone 8.
If you head over to the spec sheet of the three new iPhones, Apple provides more details about fast charging. All the three iPhones are capable of being fast charged to 50 percent in only 30 minutes. Fast charging has been present in Android devices since years now so it is nice to see Apple finally catching up to its competition here.
The inclusion of fast charging should reduce the overall charging times of the devices as well, though the difference is not going to be substantial. This is because fast charging primarily works to charge a device rapidly when its battery is very low. As the battery level reaches a certain threshold, the device is again trickle charged to increase battery lifespan.
Do note that fast charging only works when you charge the iPhone 8 or iPhone X over USB, with wireless charging speeds being slower or similar to the charging rate of the iPhone 7. Unfortunately, Apple does not bundle a fast charger with its new iPhones. This means that you will have to invest in a fast charger separately.
The cheapest fast charger sold by Apple is the 29W USB-C power adapter for the MacBook which is priced at $49. However, you can always buy a third-party USB charger which is compatible with USB-Power Delivery. The same fast charging standard is used by Google on its Pixel devices and is also supported by plenty of other flagship Android devices.
