The rule: the 3-Year Rule.
If your phone is under 3 years old and still works fine, keep it. A phone that age still gets software updates, and its hardware is plenty fast for everyday apps — upgrading early mostly buys you a shinier camera.
Upgrade when your phone hits 3 or more years, or starts failing you: battery health below 80%, apps crashing, or no more software updates. That’s when a new phone genuinely improves your daily life.
The money math matters too: a $30/month payment plan is $720 over two years. If your current phone works fine, that’s money you keep — and waiting only trims your trade-in value a little.
Educational estimate only. Based on YOUR phone’s age in years, battery health, monthly new phone cost, and trade-in value you enter. Uses the 3-Year Rule: keep phones under 3 years old that work fine; upgrade at 3+ years or when battery health drops below 80%. Prices and trade-in values change quickly. Not tech advice.
