At 3 years, your Samsung Galaxy A15 is in the window where an upgrade starts to make sense. Lithium-ion batteries typically fall to around 80% of their original capacity after a few hundred charge cycles, so battery life is usually the first thing owners notice. If yours still lasts a full day, there's no rush — if it doesn't, the picks below are a real improvement.
For most people the Samsung Galaxy S24 is the best balance of price and improvement, starting around $799. The main gains: Huge speed jump; Galaxy AI; 120Hz flagship display; 7 years of updates.
For everyday use, generally yes — but at 3 years the battery has usually lost meaningful capacity, and that's what most owners feel first.
Trade-in values move constantly with condition and carrier promotions, so treat any fixed number with suspicion. Check the current offer from Apple, Samsung, or your carrier directly, and compare it against selling privately — private sales usually pay more but take longer.
