If you're into mobile gaming, the OnePlus 15 is basically built for you. It has the fastest chip (Snapdragon 8 Elite Gen 5), the most RAM (up to 16GB), and a 165Hz display that makes everything buttery smooth. But let's talk about the heat situation because reviewers have had some things to say.

First, the good stuff. This phone absolutely crushes every game available right now. Reviewers ran Call of Duty Mobile with literally every setting cranked to maximum, including the experimental graphics options, and it ran perfectly. The 165Hz display is a real advantage in competitive games where you can actually lock 120fps consistently. Most phones cap at 120Hz, so you're getting an edge here.

OnePlus also built in some clever gaming features. Hyper Rendering improves frame efficiency by 80%, which means smoother visuals and less input lag. Bypass charging powers the phone directly when you're gaming plugged in instead of heating up the battery. That last one is actually really smart if you're a long-session gamer.

Now, the thermal reality. The OnePlus 15 has a fancy new Glacier cooling system with special steel, a cooling chip, and even "space-grade aerogel." For normal gaming sessions under 30 minutes? Zero issues, stays cool, performs great.

But push it hard for 30+ minutes on demanding games, and you'll notice it getting warm. Some reviewers found it throttles performance to manage heat. Interestingly, Samsung phones with slower chips sometimes maintain performance better during these extended sessions because their thermal management is more conservative.

Here's my honest take: unless you're a marathon mobile gamer who plays for hours at maximum settings, you'll probably never hit the thermal limits. For normal gaming, even "heavy" normal gaming, this phone is excellent. Just know that sustained maximum performance isn't infinite.
