Detailed Comparison

Performance

Google Pixel 8 Pro

Tensor G3 is purpose-built for AI workloads but still trails Snapdragon 8 Gen 2 and A17 Pro on raw performance. Runs hotter under sustained load; gaming performance is the weak spot.

Tensor G3 (4nm) + 12GB RAM + UFS 3.1 — purpose-built for Google's AI workloads, integrates the new TPU for Magic Editor / Best Take.
Tensor G3 still trails Snapdragon 8 Gen 2 and A17 Pro on synthetic benchmarks — Google's chip strategy continues to prioritize AI over raw performance.
Runs hotter under sustained gaming/4K recording than Snapdragon-based rivals — Tensor G3 thermal throttling is a recurring real-world complaint.
Three years on (2026), Tensor G3 still handles everyday Android smoothly — only sustained gaming exposes the chip-vs-Snapdragon gap.

Xiaomi 15 Pro

The Snapdragon 8 Elite (3nm) delivers a 44% single-core improvement over the previous generation and manages thermals better than most competitors. NotebookCheck awarded a 99% application performance score, placing it among the fastest phones available.

Polished matte aluminum back, IP68, refined design — most premium-feeling Pixel yet

Deal Breakers

Tensor G3 still trails Snapdragon 8 Gen 2 and A17 Pro on raw performance, especially sustained GPU; runs hotter than rivals under load
Battery life is decent (~6h SOT) but not class-leading; multi-phone drain tests place it near the back vs OnePlus 12 / iPhone 15 Pro Max
30W wired charging is modest — slower than S23+/Ultra's 45W and far behind OnePlus 11's 80W
Modem reliability issues: signal drops and lower call quality reported in real-world use vs competitors
$999 starting was a $100 increase over the Pixel 7 Pro's $899 — pricing pushback at launch

Xiaomi 15 Pro

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

Xiaomi 15 Pro

HyperOS 2 based on Android 15 brings improved fluency over HyperOS 1 and is now receiving the HyperOS 3/Android 16 update. However, the Chinese ROM lacks Google services out of the box, and the community considers HyperOS bloated with unnecessary apps compared to stock Android.

HyperOS 2 offers "substantially improved fluency and stability" over the first version
Chinese ROM only — no Google services out of the box, no Android Auto, limited language support
HyperOS described as "full of unnecessary apps" — bootloader cannot be unlocked on Chinese ROM
