Apple support for iPhone SE 2020 and IOS 18.6.2

That would be the iPhone SE (2nd generation). It originally shipped with iOS 13.4, and it can run iOS 26 – which means that it has received six major iOS updates.

While Apple has not announced their future plans for this iPhone, many other iPhone models only got five major updates before hitting "the end of the line". In addition, this iPhone has 3 GB of RAM, and if I am not mistaken, every other iPhone that can run iOS 26 has at least 4 GB. (iPhones that can run Apple Intelligence have 8 GB.). Based on this, I would not expect it to receive iOS 27.

If iOS 26 is the last version of iOS that the iPhone SE (2nd generation) gets, I would expect it to continue getting security updates for at least a year or two after subsequent versions of iOS come out. Apple's pattern has been that new features are only for the current version of iOS, but that security patches are often for both the current version and recent versions.

As LD150 pointed out …

… support by 3rd party app developers generally fizzles-out before Apple cuts off their security updates.

Our 10-year old iPhone 6s received an iOS 15 security update just two weeks ago.

Apple still support security updates on iphone 6S iOS15

As they can get iOS26, even if iOS27 may not be available, I would expect another 3 years of useful apps supported. It is usually the Whatsapps and the Snapchats of this world who decide when a phone iOS is obsolete

I am asking for a family member who currently has an iPhone 2020 SE, they would like to know when Apple will stop supporting this model, they are especially interested in when Apple will cease updating security patches for this device. They also want to know when the iOS 18.6.2 release will stop being supported. Many thanks for any information anybody can give about this..

ios 26 is the latest version for that device.

Alternatively, if they prefer to not yet upgrade to iOS 26 …

… iOS 18.7 is the current version.

Please i what to go back to the iOS 18 update please help me to update it back to iOS 18 that am using before please 😭😭😭😭😭😭😭😭😭😭😭😭😭🙏🙏🙏🙏🙏🙏🙏 please help me update it back to iOS 18

Once you’ve (presumably) upgraded to iOS 26, you can’t “downgrade” to iOS 18.

Sorry.
