What mobile phones can be used for three to four years? Can you recommend them?

The mobile phone I am using now is iPhone x. I have been using it for four years and it is still very smooth to use. I have often used Apple's iPhone series mobile phones before. After using them for 3 to 4 years, many models are still relatively easy to use and cost-effective.
