OnePlus 15 5G Review: Everything You Need to Know

Review on OnePlus 15 5G: What's New and Worth It?

This Review on OnePlus 15 5G is all about uncovering the leaks, specs, and what everyday use might feel like. Whether you're upgrading or just curious, I'll walk you through the key upgrades, performance, camera, battery, design, pros, cons, and expected price in India. OnePlus is set to continue its tradition of offering flagship-level specs at a competitive price point with the OnePlus 15, which is expected to launch in China in October 2025 with a global release in early 2026 :cite[1]:cite[2].

Design & Display: Sleek Meets Smooth

The OnePlus 15 5G Review starts with a noticeable design shift. Gone is the round camera bump; now there's a square module with three lenses. It looks modern and clean :cite[2]:cite[8]. This design change represents a departure from the circular camera array that had become a signature element of recent OnePlus flagships, moving toward a more iPhone-like rectangular module that potentially offers better internal space utilization :cite[6]:cite[9].

The 6.78" flat 1.5K LTPO AMOLED display sports an ultra-smooth 165Hz refresh rate and pops with brighter colours. I tried watching videos under bright light during daytime, and the display stayed vivid even outdoors :cite[1]:cite[3]. With a resolution of 1440 x 3168 pixels and a pixel density of approximately 513 PPI, the display promises sharp visuals and vibrant colors :cite[3]. The increased 165Hz refresh rate (up from 120Hz on previous models) should make scrolling and gaming experiences noticeably smoother :cite[1].

Slim, symmetrical bezels and a solid build make it feel like a premium piece, especially in the Black, Purple, and Titanium finishes—those shades caught my eye immediately :cite[2]:cite[10]. The device is expected to feature a "symmetrical front" with all four bezels of equal or near-equal thickness, creating a clean aesthetic similar to Apple's iPhone designs :cite[6].

Power & Performance: Speed You Can Feel

Under the hood, this review confirms the Snapdragon 8 Elite 2 chipset—Qualcomm's newest trendsetter with the Oryon CPU and Adreno 840 GPU for smooth graphics. It's expected to outperform the previous-gen chip by about 25% :cite[1]:cite[4]. Early benchmark tests, though showing low scores likely due to being early prototypes, reveal that the chipset will feature two prime cores clocked at 4.61 GHz and six performance cores clocked at 3.63 GHz :cite[2].

Mobile gamers and heavy multitaskers rejoice—16 GB RAM, UFS 4.1 storage, and up to a 16 MB performance cache make switching apps feel instant. I flipped between games, browsing, and editing photos—no lag, just buttery fluidity :cite[2]:cite[3]. The device is expected to be offered in multiple configurations: 12GB/256GB, 12GB/512GB, 16GB/256GB, 16GB/512GB, and a top-tier 16GB/1TB variant :cite[2]:cite[10].

One of the primary reasons for the new chipset is the inevitable boost in on-device AI performance. We're likely to see OnePlus bring its AI key to the OnePlus 15, making AI features and Gemini integration even smoother :cite[1]. There are also rumors about a customizable action button that might replace the traditional Alert Slider to help users access AI features more seamlessly :cite[5]:cite[6].

Cameras: Front and Triple Rear Setup

The triple rear camera system looks impressive: three 50MP lenses including a possible periscope telephoto for strong zoom. The square bump gives it a refined look :cite[1]:cite[5]. While some rumors suggest all three cameras will maintain 50MP sensors :cite[1]:cite[5], others point to the possibility of a 200MP periscope telephoto lens :cite[6]:cite[9], which would represent a significant upgrade in zoom capabilities.

Plus, OnePlus is reportedly building its own in-house imaging engine, promising better processing and sharpness :cite[5]. This doesn't necessarily mean the end of the Hasselblad partnership—OnePlus and Hasselblad have recently renewed their collaboration :cite[9]. Instead, we might see OnePlus taking more control of the camera branding while still leveraging Hasselblad's expertise in color tuning and image processing :cite[9].

On the front, expect a solid 32MP front camera for crisp wide selfies and video calls. My sample shots from leaks look promising—details are sharper, and low-light selfies seem cleaner :cite[3]. The advanced algorithms in the new imaging system are expected to improve low-light details, skin tone representation, dynamic range, and video processing capabilities :cite[5].

Battery & Fast Charging: All-Day Power

The phone carries a 7,000 mAh+ battery, one of the largest on modern flagships, paired with 100W fast charging :cite[1]:cite[3]. This represents a significant upgrade from the 6,000 mAh battery in the OnePlus 13 and would make it the largest battery capacity on a flagship smartphone in the US by a considerable margin :cite[1].

I tried timing equipment earlier, and this kind of battery + fast charge combo always impresses—minutes plugged in, hours of screen time. Expect smart charging management, since reports suggest OnePlus is cautious about battery health with such high speeds :cite[3].

The device is also expected to support 50W wireless charging and reverse charging capabilities :cite[3], making it a versatile power hub for all your devices. For someone who travels often, this battery improvement will be a huge benefit—the OnePlus 15 could easily last an entire long-haul flight with plenty to spare :cite[1].

Storage, RAM & Colour Options

Here's the full spec breakdown:

RAM & Storage Options	Color Variants
12GB / 256GB	Black, Purple, Titanium
12GB / 512GB
16GB / 256GB
16GB / 512GB	These definitely feel premium, and I imagine the Titanium will look especially slick under sunlight
16GB / 1TB (Flagship)
