Easily one of the best purchases that I have made and well worth its price.
Pros:
- SD 8 Gen 2 is fast and very power efficient. The performance is indistinguishable in day to day usage when compared to SD 8 Gen 3 on a OnePlus 12 with UFS 4.0. Even though the 12R has a UFS 3.1 storage, you are unlikely to notice any difference whatsoever without running benchmarks or checking the specifications. In real life day to day usage, I have not found any difference and I am a power user who uses a lot of applications and use the phone over 8 Hours a day.

- The vapour chamber handles the cooling very well which keeps the device at excellent temperature even when playing games for an extended duration. It almost never goes over 38c.

- The display has the same features as the OnePlus 12 (the resolution is relatively lower but it's not noticeable to the naked eye without magnification) and this is one of the best displays that you will come across. The HDR performance is also some of the best I have seen and it is a completely different experience. This can also be seen in the HDR shots taken with cameras. I'd suggest going to a OnePlus experience center and searching for 12K HDR videos on YouTube to get a better idea. Note that the 4,500 nits mentioned is only the HDR brightness at a small white portion of the display under sunlight. This is NOT the max brightness of the full display. But it is bright enough to use under direct sunlight.

- Battery life is very impressive with over 8 hours of SOT and the 100W included charger fully charges it in about 35 mins.

- Also love that the display can be used even when your hands are wet unlike most other smartphones

- The bezels are extremely slim and the chin is smaller than the one on the OnePlus 12. I do wish it was equal all around though.

Rather than cons, I'll just mention what it lacks.
- Wireless charging
- Telephoto camera

That's pretty much it. If you are looking for a smooth and reliable device with solid performance, battery life, fast charging, decent cameras and display experience, I would easily recommend this. Sure the cameras may not be as good as an iPhone 15 (81k) or a Pixel 8 (83k) but they also cost around 80% more than the OnePlus 12R.
