The company plans to release an update for Pokémon GO around February 28, 2018 that will end support for older iPhone and iPad models incapable of updating to iOS 11, including the iPhone 5 and iPhone 5c.
The complete list of affected devices, released between 2011 and 2013:
- iPhone 5
- iPhone 5c
- iPad (4th generation)
- iPad (3rd generation)
- iPad mini (1st generation)
- iPad 2
More specifically, players who attempt to access Pokémon GO using any of the devices listed above will no longer be able to sign in and will see a message stating that they need to switch to a supported device, suggesting server-side changes.
Niantic said the change is a result of improvements to Pokémon GO that push the game beyond the capabilities of previous iOS versions, likely including a new AR+ mode based on Apple's ARKit for iPhone 6s and newer.
