Is iPhone 7plus compatible to iOS 15

Hello

iOS 15 is compatible with iPhone 7 and iPhone 7 Plus. Be aware it can longer get any other update after iOS 15 so at some point if apps no longer work properly or you get message to update apps or any other errors. You would want to consider looking into a newer device. Its not listed as Vintage or obsolete now but is possible in the future due to not being able to handle the most recent updates available.

• iOS 15 and iPadOS 15 are compatible with these devices - Apple Support
• Update your iPhone or iPad - Apple Support
• If your iPhone or iPad won't update - Apple Support
• Obtaining service for your Apple product after an expired warranty - Apple Support
• iPhone - Apple

Hope this helps

Yes, an iPhone 7 can currently be updated to 15.7.4.
