Re: “why my iphone 8 cant update to ios 26”


The iPhone 8 has only 2 GB of RAM. Only one of the iPhones that can run iOS 26 has as little as 3 GB of RAM, and it is the straggler. All of the others have from 4 to 8 GB of RAM. So lack of RAM would likely be one reason.


Then there is the Neural Engine. All iPhones that can run iOS 26 have at least 8 Neural Engine cores. The iPhone 8 has a rudimentary Neural Engine with only 2 cores.

You may want iOS 26 on your iPhone 8, but you can't have it. The iPhone 8, which ran iOS 11 when Apple came out with the first variants in September 2017 (more than eight years ago), cannot update past iOS 16. It did not receive iOS 17 or 18, which should have told you that it is not eligible for iOS 26.


If you want iOS 26, you will need to purchase a new iPhone that is compatible with it.


iPhone models compatible with iOS 26 - Apple Support


I would suggest one of the newer models on the list, as some older phones (like the 11-series ones) have received so many major iOS updates that it seems unlikely that they will receive iOS 27. (Also, older models would only be available used, and there can be risks to buying a used iPhone such as getting one that is Activation Locked, that is carrier-locked, or that will soon need a new battery.)


If you want Apple Intelligence, that has higher requirements. Many older phones that are compatible with iOS 26 do not have the required 8+ GB of RAM to run Apple Intelligence. For more detailed requirements, see
