OnePlus 15 Infinite Black 512GB

The OnePlus 15 packs a 7,300mAh battery, the biggest in any North American consumer smartphone, and it delivers two-day endurance that owners rave about. Performance from the Snapdragon 8 Elite Gen 5 is top of the charts, but the camera and feature set lag behind the competition. At $850 to $1,195 depending on the vendor, it's a battery-first flagship that trades polish for endurance.

The Snapdragon 8 Elite Gen 5 clocked at 4.61GHz is an absolute monster. With 16GB of RAM backing it up, this thing sits in the 99th percentile for performance in our database. Everything feels fluid, apps open instantly, and the tri-chip system with dedicated Wi-Fi and touch response chips keeps things snappy even under load. Owners describe the experience as 'insane' and 'incredible', and the numbers back that up.

Against the Samsung Galaxy S26 Ultra, the OnePlus 15 wins on battery life without breaking a sweat, that 7,300mAh cell dwarfs Samsung's offering. But the S26 Ultra fights back with a more polished camera system and a richer feature set. The Google Pixel 10 Pro has the computational photography edge, though its battery life is a known weak spot that OnePlus owners specifically call out as a reason they switched. The iPhone 17 brings ecosystem polish but can't touch this battery capacity. For raw endurance and performance per dollar, the OnePlus 15 is hard to beat.

Pricing is all over the map right now. US listings range from $850 to $1,195, which is a $345 spread depending on where you shop. At the low end, you're getting 99th percentile battery and performance for under $900, which is frankly ridiculous value. At the high end, you're creeping into Galaxy S24 Ultra territory where the camera and feature set start to look more competitive. Shop around before you commit.

The OnePlus 15 is the battery king, plain and simple. That 7,300mAh cell is the biggest in any consumer smartphone in North America, and it lands in the 99th percentile in our database. Owners are reporting two full days of use without reaching for a charger, which is the kind of endurance that makes you forget battery anxiety was ever a thing. Pair that with 80W wired charging and you're looking at a phone that refuels faster than most people finish their morning coffee.

If camera quality is your top priority, look elsewhere. The OnePlus 15's camera ranks 97th percentile in our database, but real-world feedback consistently places it a generation behind the Pixel 9 Pro XL and Galaxy S24 Ultra. The feature set also lands at just 45th percentile, so if you want an IR sensor, wireless charging, or a rich ecosystem of extras, this isn't your phone. And if you hate plastic backs on premium devices, the build materials may disappoint despite the 99th percentile build score.

The OnePlus 15 is a battery and performance powerhouse that makes a strong case for itself at the right price. The 7,300mAh cell and Snapdragon 8 Elite Gen 5 are best-in-class, and owners are genuinely thrilled with the two-day battery life. The camera is good but not great, the plastic back feels cheaper than the price suggests, and the missing wireless charging is a head-scratcher. If you can find it near the $850 mark, this is one of the best value flagships on the market.
