We're learning more about the type of charger the next iPhone models might use and whether it'll support fast charging.
Japanese site Macotakara has claimed the next generation of iPhone models will continue to use the Lightning port, and that Apple will bundle the same 5W charger and USB-A to Lightning cable in the box. Annoyingly, this is being reported as a way for Apple - a mega-rich companies - to save money by maintaining production costs. So, if you want to charge your iPhone faster, you'll have to separately buy 12W charging accessories.
Keep in mind this report follows numerous conflicting leaks, which have toggled between the next iPhone models featuring Lightning ports to the next iPhone models making the switch toSB Type-C protocol with fast charging cables, something many smartphones use. If you recall, Apple began shipping an 18W USB-C charger with its iPad Pro last autumn, so many expected Apple would go that way with the next iPhone lineup, too.
Let's say Apple does indeed stick to Lightning port and 5W charger, but it also increases internal battery capacities on the next iPhone model. Then, that means it will take you a lot longer to charge the new iPhone models to 100 per cent.
While we can’t confirm Apple will definitely go this route, another recent piece of evidence comes from an @OnLeaks leak that pointed toward Apple including Lightning charger ports on the phones, rather than transition to USB-C.
