Multiple rumors have suggested that Apple plans to stop offering power adapters and EarPods with future iPhone models, shipping the devices with just a charging cable.
At the current time, Apple ships iPhones with either an 18W power adapter or a 5W power adapter depending on device, but in 2020, those who need a power adapter may need to purchase one separately from Apple or a third-party company.
Eliminating the power adapter and EarPods from the iPhone's box will allow Apple to lower the production costs of the iPhone 12 lineup, which are equipped with expensive 5G hardware.
Apple is developing a new 20W USB-C power adapter that is likely to be sold separately to replace existing iPhone charger options, and it seems other smartphone manufacturers like Samsung are going to follow Apple's lead and take similar steps to eliminate accessories.
