Active stylus support (Moto Pen Ultra) that works even on the cover screen, a Z Fold limitation

Detailed Comparison

Design & Build

Motorola Razr Fold

Motorola's first book-style foldable trades the iconic flip for a Samsung-like book form, with a Material Expressive look, a flat-folding hinge and a notably heavy body.

Motorola's first book-style folding phone is a premium option, not the budget-friendlier alternative the category could use, with a 6,000mAh battery, top-tier chipset and serious camera hardware.
At 243g it's about 28g heavier than the Galaxy Z Fold 7, largely because of the camera array, though it feels balanced and not heavy in the hand.
The design is Google Material Expressive instead of a misguided attempt to match Apple.
Motorola leveraged decades of hinge engineering to pull the screen taut, resulting in a surface that is startlingly flat and masks the crease.

Undercuts the Galaxy Z Fold 7 by about $100 ($1,899 / £1,799) and includes a case plus a 90W charger in the box

Best book foldable you can actually buy in the US, since the Oppo Find N6 and Honor Magic V6 aren't sold there

Deal Breakers

Uses the non-Elite Snapdragon 8 Gen 5 in a $1,899 flagship — a clear cost-down some reviewers find disappointing
Heavy at 243g (≈28g more than the Galaxy Z Fold 7) and only IP48/IP49 rated, not full IP68
Motorola's poor track record for timely updates, plus a genuine source conflict over whether it gets 7 years or only 3 years of OS updates
Foldable repair costs and Motorola's screen-peeling warranty history are recurring trust concerns

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

The build feels relatively sturdy with a zero-gap hinge and flush closure, though the soft inner screen still makes dust and dirt a concern.

Xiaomi 15 Pro

Premium glass-and-metal construction with flat aluminum sides and IP68 water resistance. At 8.35mm thin and 213g, it's impressively slim for housing a 6,100mAh battery. Available in four colors including Spruce Green and Rock Grey.

Impressively thin at 8.35mm despite housing a massive 6,100mAh battery
IP68 dust and water resistance (1.5m for 30 minutes) provides genuine peace of mind
Glossy back finish is a significant fingerprint magnet, especially on the Silver variant

Performance

Motorola Razr Fold

Snapdragon 8 Gen 5 with 16GB RAM — fast for everyday use and surprisingly good in long sessions, but the choice of the non-Elite chip in a $1,899 phone is the headline criticism.

Motorola stuck Qualcomm's excellent Snapdragon 8 Gen 5 (16GB RAM, 512GB) inside its first full-fold flagship.
With a phone this expensive it is a bit disappointing Motorola couldn't go all the way with the Elite chip.
In a 20-minute stress test the Z Fold 7's 8 Elite was ~10% better on the first loop, but the Razr Fold ran better through the 20 minutes and ended ~20% ahead on sustained performance with similar thermals.
Recording 4K120 for a long time makes the Snapdragon CPU run quite hot, though it cools down fairly fast.
The non-Elite chip, 243g weight and IP49 dust rating could be causes for concern, even if the experience is smooth.

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.

Snapdragon 8 Elite achieves Geekbench 6 single-core of 3,157 — a 44.4% leap over Snapdragon 8 Gen 3
Better thermal management and sustained performance than competitors like the Oppo Find X8 Pro
Some throttling under prolonged heavy gaming loads, though managed better than peers
