Your OnePlus 9 is 5+ years old, which is past the point where most phones stop receiving full software and security updates and where battery wear is significant. This is a genuine upgrade case — and the gains below are large enough that you'll notice them daily, not just on a spec sheet.
For most people the OnePlus 12 is the best balance of price and improvement, starting around $799. The main gains: Snapdragon 8 Gen 3; 100W fast charging; Brighter display; Bigger battery.
It still works, but at 5+ years you're likely past full software support and well into battery wear. Most owners at this age notice a real difference after upgrading.
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.
