The OnePlus 15 is destined to rank among the best phones of 2026 — oh, and it's $600 off and comes with a $100 gift card

If you're looking for one of the best Android phone experiences of 2026, I just found a OnePlus 15 deal that should scratch the itch. Head to Best Buy and grab the unlocked phone today and you'll be eligible for up to $600 of trade-in credit. As if that wasn't enough, Best Buy will also throw in a free $100 gift card, just for kicks.

I don't need to be a fortune teller to tell you that the OnePlus 15 is certain to rank among the best Android phones of 2026, and if you're able to claim the max trade-in credit from this deal, getting the device for $399.99 with a $100 gift card seems like a no-brainer. 

A nearly-perfect phone gets a nearly-perfect discount

OnePlus 15 512GB: $999.99 From $399.99 with trade-in, plus $100 gift card at Best Buy

Don't let the derivative design fool you, the excellent OnePlus 15 is all innovation under the hood. Trade in an old or broken phone at Best Buy and you'll score up to $600 off the flagship, plus the retailer will slap on a free $100 gift card. Activate the device with Verizon or AT&T and you'll get another $100 off. It just keeps getting better, doesn't it?

✅Recommended if: you simply want one of the best flagship phones on the market, period; you value battery life, performance, and durability in your devices; you have a newer device to trade in.

❌Skip this deal if: you want a phone with Qi2 magnets or a ton of AI software features; you can get a better deal through your wireless carrier. 

The OnePlus 15 improves upon its "perfect" predecessor in a few key areas, coming complete with a gorgeous and eye-friendly 165Hz OLED display, a durable construction with a IP69K rating, and outstanding camera quality that could easily challenge the best devices from Samsung or Google. 

Under the hood, the phone is powered by the Snapdragon 8 Elite Gen 5 chipset, plus you get 16GB of RAM and a ridiculous 7,300mAh battery that will last up to three days on a single charge. As our 4.5/5-star review stated, the OnePlus 15 features "the fastest processor, the fastest charging, the best battery life, the best OLED, and the best ingress protection rating of any flagship phone you'll find today". Enough said. 

So what's the catch? Well, the OnePlus 15 doesn't have Qi2 charging support, there's no alert slider, and the AI features are a bit lacking compared to other modern flagships. Those issues are all pretty minor, so I'd say the main barrier to entry with this deal is the trade-in requirement.

Best Buy can be a bit stingy and arbitrary with its trade-in credit. Sending in the OnePlus 13 or Galaxy S25 Ultra, for instance, will only land you $300 and $400 of credit, respectively, while devices like the Google Pixel 10 Pro will earn you the max amount.

Needless to say, it's worth using Best Buy's trade-in tool to see how much you can get. Play your cards right and you could get one of the year's best phones at a budget phone price, AND $100 of free Best Buy cash to use on whatever you'd like. Not too shabby for a device of this caliber, if you ask me.
