The OnePlus 15 is just a week away from its China launch, and the company clearly isn’t done hyping it up. In true OnePlus fashion, it’s dropping new teasers left and right – this time, focusing on raw power and performance.
OnePlus flexes hard on cooling and gaming upgrades
We already knew plenty about the OnePlus 15, but OnePlus is determined to keep the excitement going before the big reveal. The latest teasers dive deep into performance, and according to the company, this phone is packed with industry-first upgrades that supposedly take speed and cooling to a whole new level.
Now, whether that’s real innovation or just marketing talk, we’ll find out once the phone is in our hands. But the numbers and terms do sound impressive. The phone introduces a new Glacier cooling system made from ultra-thin, hand-tearable steel that reportedly dissipates heat twice as fast as before.

There’s also a new “Glacier” chip air conditioning architecture – basically a custom-designed system that lowers the core temperature of the chip – and a “Glacier” aerogel layer, which uses a space-grade insulation material to keep your fingers cool while gaming.
And speaking of gaming, for gamers, OnePlus is taking things even further with what it calls the first-ever “Gaming Hand Cooling Model.” It targets ten specific heat zones on the device, keeping your fingers cool during long gaming sessions.
We've outfitted the OnePlus 15 with cutting-edge cooling technology, from the chip to the midframe, from the materials to the structure. Layer by layer, we guarantee consistent performance even at peak performance.

So, yeah, clearly, OnePlus has gamers in mind this year. The 165Hz refresh rate display should already feel buttery smooth, but the company says it has completely rewritten the Android touch-display framework to improve touch-display synchronization – so every swipe, tap, or flick feels more instant and precise.
There’s also a new G2 gaming network chip, designed to deliver stronger Wi-Fi and cellular performance in areas where other phones struggle. And as a cherry on top, OnePlus has added a new gyroscope with console-grade specs for faster response times and more accurate controls.

So yeah – if OnePlus is to be believed, the 15 will be a beast when it comes to performance.
Big battery, fast charging, and all-around upgrades
Just yesterday, OnePlus confirmed one of the most exciting parts – a huge 7,300mAh battery with 120W wired and 50W wireless charging. Inside, it’s powered by the Snapdragon 8 Elite Gen 5 and backed by 12 GB of RAM.
Put simply, this thing is shaping up to be a monster. The OnePlus 15 already sounds like a strong follow-up to the OnePlus 13 – one of the best Android phones of its time – but this time it’s coming with a fresh new design, dropping the signature circular camera island for a cleaner look.
Would you buy a phone mainly for better cooling and gaming performance?

Can OnePlus 15 really go toe-to-toe with iPhone and Galaxy?
I genuinely think the OnePlus 15 has a real shot at shaking things up. With those specs – and assuming it all performs as promised – it could go head-to-head with the Galaxy S26 Ultra and iPhone 17 Pro Max without breaking a sweat.
If OnePlus manages to keep the price steady and make the phone easier to get globally, it might just be the perfect pick for anyone tired of choosing between Apple and Samsung. Because honestly, a flagship with that kind of battery, cooling system, and gaming focus? Yeah, that’s the kind of competition the Android world needs right now.
