Smartphone users fall into different categories, but the two most common ones are the power users, those who push their phones to the fullest, and the casual, everyday users who want to keep a smartphone for calling, texting, or browsing social media. Power users tend to be tech enthusiasts who are willing to spend more to keep up to date on the latest model. Sadly, a lot of the fault comes from planned obsolescence. Planned obsolescence is intentional limitations placed by the manufacturer, which are made obvious by your hardware or software, whether it can't support new features or does so poorly (like AI). Truly, the best time to upgrade is when your carrier or the phone manufacturer is offering a significant discount.
