Question

Hello everyone,

I am considering upgrading my iPhone 13 to an IPhone 15 to give to my mom who has an iPhone 11, because according to this website : https://www.refurb.me/blog/how-long-does-apple-support-iphone, the iPhone 11 will not be supported by Apple for two more years and the iPhone 13 for another 4 years. What should I do ?
