According to Arcuri, he has predicted that with the 2017 iPhones, Apple is expected to introduce 3GB of RAM across all three models, meaning that the iPhone 7s, 7s Plus, and the iPhone 8/Edition will pack 3GB of RAM as opposed to the current configuration which we mentioned above.
What this means for users is that the increased RAM would allow for more data to be stored in memory, which should help reduce reloading times for apps that are already opened, or prevent browser tabs in Safari from refreshing whenever you switch. In addition to the upgraded RAM, Arcuri also claims that the 2017 iPhones will continue to use Lightning connectors, but will feature USB-C Power Delivery that will support faster charging.
In the past faster charging for the iPhone meant using a charger like the iPad’s charger, but presumably this will be faster. Whether or not it will be on par with the other quick charging solutions we’ve seen arrive on Android phones remains to be seen, so until then do take it with a grain of salt.
