What Reviewers Agree On

The 6,000mAh battery with 100W wired and 50W wireless charging provides outstanding battery life and the fastest charging in its class
The 2K LTPO AMOLED display with up to 4,500 nits brightness is stunning for media consumption and outdoor use
Price-to-performance ratio is the best in the flagship segment, consistently undercutting Samsung and Apple by $200-400

Detailed Comparison

Display

OnePlus 15

The 6.7-inch 2K LTPO AMOLED panel pushes to a staggering 4,500 nits peak brightness with 1-120Hz adaptive refresh — one of the brightest smartphone displays available.

The 2K resolution LTPO panel is gorgeous with exceptional color accuracy, deep blacks, and 4,500 nits peak brightness that makes outdoor visibility outstanding
1-120Hz adaptive refresh rate with LTPO 2.0 ensures butter-smooth scrolling while preserving battery life during static content
The curved edge display looks elegant but can occasionally cause accidental palm touches during one-handed use

Xiaomi 15 Pro

The 6.73-inch 2K LTPO AMOLED is a technical marvel, hitting 3,200 nits peak brightness while consuming 24% less power than the Xiaomi 14 Pro's display. The 1920Hz PWM dimming reduces eye strain, though some users report OLED smear at low brightness levels.

3,200 nits peak brightness with 24% lower power consumption than the predecessor — outstanding efficiency
2K resolution (2670x1200) with 120Hz LTPO and 1920Hz PWM dimming for reduced eye strain

What Reviewers Agree On

Snapdragon 8 Elite delivers top-tier performance with excellent thermal management
Battery life is class-leading thanks to the 6,100mAh silicon-carbon cell and efficient display
Display quality is outstanding with 3,200 nits brightness and remarkable power efficiency
Camera system is good but not best-in-class — ultrawide is the weakest lens
China-only availability is a significant limitation for global buyers

Deal Breakers

No global availability — Chinese ROM only with no Google services out of the box
HyperOS described as bloated with unnecessary apps
Bootloader cannot be unlocked on Chinese ROM versions

Camera

OnePlus 15

The Hasselblad-tuned triple camera system delivers natural colors and excellent portraits, with a 50MP main, 50MP ultrawide, and 50MP 3x periscope telephoto.

Hasselblad color science produces warm, natural tones that look true to life — portraits are particularly impressive with excellent skin tone rendering and bokeh
The 3x periscope telephoto delivers sharp, detailed shots and the 50MP sensor means cropping to 6x still produces usable results
In challenging mixed-lighting conditions, HDR processing can occasionally produce artifacts and inconsistent exposure between the three lenses
Video recording at 4K60 is excellent with effective stabilization, though Dolby Vision HDR video still trails iPhone in dynamic range

Xiaomi 15 Pro

The triple 50MP Leica Summilux system delivers solid results with a standout 5x periscope telephoto. The main sensor with f/1.44 aperture handles most scenarios well, and AI Zoom makes 20x digital shots usable. However, the ultrawide is the clear weak link, and the system can't quite match the Vivo X200 Pro's imaging prowess.

5x periscope telephoto (120mm) delivers sharp, detailed results up to 10x — AI Zoom usable at 20x
Main 50MP sensor with f/1.44 aperture and Leica color science produces pleasing, natural-looking images
Ultrawide camera (50MP JN1) is the weakest lens — frequently criticized by users as noticeably below main and telephoto quality
Camera scored 82% on NotebookCheck — the lowest individual category score, behind the Vivo X200 Pro
