OnePlus 15 Full Review: 165Hz Display, 120W Charging, and DetailMax Camera Engine Explained

The OnePlus 15 has officially landed in India, and it’s carrying a price tag that might make your wallet sweat—₹72,999. For years, OnePlus fans have begged for two things: a battery that doesn’t die by tea-time and a screen that feels faster than a Formula 1 car. OnePlus heard you, but they’ve also charged you for the privilege.

With a monster 7,300mAh battery and a world-first 165Hz 1.5K display, this phone is clearly aimed at the gamers and power users. But here is the real truth: OnePlus has also killed its famous Hasselblad partnership to build its own “DetailMax Engine.” Is it a masterstroke or a massive mistake? Let’s find out.

QUICK SPECS TABLE

DESIGN & BUILD (Deep Dive)

OnePlus has finally ditched the circular “watch-dial” camera island we saw on the OnePlus 11, 12, and 13. Instead, we get a rectangular module shifted to the top-left. It feels more “iPhone-ish” yet maintains that classic OnePlus “Sand Storm” texture that feels like premium stone in your hand.

At 211 grams, it’s not light, but considering there’s a 7,300mAh battery inside, it’s a modern engineering miracle that it’s only 8.1mm thick. The build is a sandwich of Gorilla Glass Victus 2 on the front and “Crystal Shield Glass” on the back, held together by a high-grade aluminum frame.

The real truth is: This is the toughest OnePlus ever. It carries an IP69K rating, meaning you can literally blast it with high-pressure hot water (don’t try this at home, though) and it will survive.

DISPLAY & VISUALS: A Gamer’s Dream

Let’s talk about the elephant in the room: the 1.5K resolution. Yes, OnePlus “downgraded” the resolution from the 2K panels of previous years. But they did it for a reason: 165Hz.

This is the first phone in the world to offer 165Hz at 1.5K resolution. While regular scrolling happens at 1-120Hz (thanks to LTPO), the 165Hz kicks in the moment you fire up a supported game. Outdoor visibility is excellent with 1,800 nits of High Brightness Mode, though it claims a peak of 4,500 nits in HDR content.

PERFORMANCE & GAMING

Powered by the Snapdragon 8 Elite Gen 5, this phone is a beast. In our stress tests, it didn’t even break a sweat.

• Antutu Scores: Crossing the 3 million mark easily.
• Gaming: We played Genshin Impact at max settings for 60 minutes. The frame rate stayed a locked 60 FPS (and up to 120 FPS with HyperRendering), and the temperature never crossed 42°C.
• Multitasking: With 16GB of LPDDR5X RAM, you can keep 40+ apps open without the phone killing a single one in the background.

CAMERA: Life Without Hasselblad

OnePlus has ended its partnership with Hasselblad. In its place is the DetailMax Engine.

The hardware is solid:

1. Main: 50MP Sony IMX906 (OIS) – Great natural colors.
2. Ultra-wide: 50MP – Sharp, but has some distortion at edges.
3. Telephoto: 50MP (3.5x Optical) – This is the star. Portrait shots are creamy with excellent edge detection.

Don’t waste your money if you want the world’s best camera phone. While the OnePlus 15 is “good,” it still lacks the skin-tone accuracy of an iPhone 17 or the pure “wow” factor of a Samsung S25 Ultra. It’s a social-media-ready camera, not a professional tool.

BATTERY & ENDURANCE: The New Gold Standard

This is where the OnePlus 15 absolutely destroys the competition.

• Capacity: 7,300mAh (Silicon NanoStack technology).
• Real World: In our heavy usage test (5G, gaming, YouTube, Camera), we got 11 hours of Screen-On Time (SOT). For most people, this is a 2.5-day battery.
• Charging: The 120W charger takes the phone from 1% to 100% in about 30 minutes. That is insane for a battery this size.

THE COMPETITION

OnePlus 15 vs Samsung Galaxy S25 vs iQOO 15

The Winner: If you want raw power and battery, the OnePlus 15 wins. If you want software longevity and a compact feel, the Samsung S25 is your pick. If you want a pure gaming phone with a slightly lower price often found on sale, look at the iQOO 15.

FINAL VERDICT

Buy it if:

• You are a heavy gamer who needs that 165Hz edge.
• You hate carrying a power bank (that 7,300mAh battery is no joke).
• You want a phone that can survive a literal rainstorm (IP69K rating).

Skip it if:

• You want the absolute best camera in the 80k segment (Buy an iPhone or Pixel instead).
• You prefer small, compact phones (This is a big boy).
• You are happy with your OnePlus 13 (The performance jump is there, but not life-changing for casual users).
