Motorola Razr Fold vs Xiaomi 17 Ultra

Motorola Razr Fold

Historically the foldable Achilles heel — but Motorola invested in hardware and software here, and DxOMark ranks it the best camera in any foldable.

• DxOMark rates the Razr Fold the #1 camera among foldables — roughly 8th overall across all phones — with a Gold Label.
• A 50MP main (f/1.6, OIS), a 50MP ultrawide (12mm, 122° FOV, f/2.0) and a third 50MP camera — all selfies can use the best 50MP main.
• This is without question the best Motorola camera I've ever used.
• Comes up just short of modern flagships like the iPhone 17 Pro, Find X9 Pro and Xiaomi 17 Ultra, with a DxOMark score of 164 points.
• Took it for a street-photography spin and came away genuinely impressed — the camera hardware was what caught attention.
• Highest-quality camera in a folding phone in the US — better than the Pixel 10 Pro Fold and Galaxy Z Fold 7, which use older sensors.

Xiaomi 17 Ultra

The reason this phone exists. A 1-inch LOFIC main sensor and an industry-first continuous mechanical optical zoom put it at or near the top of the smartphone camera rankings — but JPEG processing and a steep learning curve divide opinion.

• The 17 Ultra keeps a 1.0"-type main sensor while most makers go smaller; its main camera is quite probably the best of its kind and the phone is among the best for taking pictures currently on the market, possibly the best.
• It combines two technologies not seen together in mobile before — a 1-inch LOFIC sensor in the main camera and a mechanical periscope with continuous optical zoom — reducing ghosting and capturing highlights and shadows in a single exposure.
• Camera kit details: 23mm 50MP 1-inch main at fixed f/1.67, a 200MP 75–100mm true mechanical optical zoom (not a digital crop), and a 14mm 50MP f/2.2 ultrawide.
• This is one of the best camera systems ever used on a smartphone, as was the 15 Ultra.
• The sensor is excellent, but Xiaomi's automatic JPEG post-processing is an absolute disaster, and distant faces can look like paint blobs.

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 17 Ultra

Snapdragon 8 Elite Gen 5 keeps it firmly in the flagship tier with strong gaming, though sustained behaviour and thermals draw mixed verdicts.

• The Snapdragon 8 Elite Gen 5 brings ~20% faster CPU, ~23% faster GPU and peak speeds up to 4.61GHz over the previous generation.
• The iPhone has a slight single-core edge but the Xiaomi takes the lead in Geekbench multi-core.
• Genshin Impact at very high settings ran 30 minutes at an average of 55.3fps with a 1% frame drop, while lighter titles like Honor of Kings averaged 107.8fps; both front and back stayed around 40°C.
• It delivered significantly better gaming performance than the Xiaomi 17 Pro and performed better in the stress test than the 17 Pro with the same 16GB of RAM.
• Delta Force ran for 23 minutes straight with impressive thermal management and no notable heating.

Motorola Razr Fold

The standout: the largest battery in the book-foldable space delivering class-leading endurance, plus 80W wired charging — three times faster than the Galaxy Z Fold 7.

• Lasting an impressive 14 hours 31 minutes, the Razr Fold is officially the best notebook-style foldable for battery life (16h10m with refresh-rate optimized).
• The Galaxy Z Fold 7 managed only 10h44m in the same test, with a 4,400mAh battery versus the Razr Fold's 6,000mAh cell.
• I found the battery basically impossible to kill in a single day, even with the Fold's hotspot supplying an entire office internet connection over 12 days.
• It charges at 80W wired — over three times as fast as the Galaxy Z Fold 7's 25W — plus 50W wireless and 5W reverse, with a 90W charger and a case included in the box.
• The 6,000mAh cell is colossal — about 20% larger than the Pixel 10 Pro Fold's — though there's also more display to power.
• If you use the camera a lot or run games, the battery does drain quite quickly and you may need an afternoon top-up.

Xiaomi 17 Ultra

The single biggest divide in the coverage: lab tests record an excellent active-use score, but the global model's smaller battery, ~10%/hour real-world drain and heat make endurance inconsistent. Charging stepped down to 90W wired / 50W wireless.

• The global 17 Ultra earned an excellent active-use battery score of over 19 hours, charging 0–70% in half an hour and to full in just 43 minutes.
• After 3 months a user still had around 45% battery left at the end of the day when not using the camera intensively.
• For a 6,000mAh battery, ~4 hours of screen-on time over a full day was disappointing — the S26 Ultra's 5,000mAh cell matched or beat it under the same camera-and-navigation use.
• In a head-to-head extreme test the 17 Ultra ran hotter and lost more battery than the OnePlus 15 and Oppo Find X9 Pro at nearly every stage, finishing about 8 hours 8 minutes at 43.7°C.
• The global model holds ~800mAh less than the China version and drains roughly 10% per hour, so it can't last a full 15-hour day the way the China version does.

Motorola Razr Fold

The surprise strength — Motorola's foldable software is widely called the best balance of Pixel simplicity and Samsung multitasking, undercut only by Motorola's update-timeliness history.

• Motorola nailed the software — it feels like the perfect middle ground between the Pixel and Samsung approaches to book foldables, with a laptop mode that turns the bottom half into a trackpad.
• The Razr Fold is winning me over with something not on the spec sheet — superb multitasking software.
• Given Motorola's awful track record for timely updates, you've got to be ready to live with the little launch bugs for a while.
• Motorola promises 7 years of Android version and security updates — best-in-class and a huge jump from last year's 3-year commitment.
• Counterpoint: Motorola is only committing to 3 years of Android upgrades and 5 years of security patches, so versus Samsung's 7 years it's really no contest.

Xiaomi 17 Ultra

The phone's most consistent weakness. HyperOS is widely seen as not up to par with the hardware, with camera-app limitations and an iOS-clone feel — though a minority of long-term owners disagree.

• The 17 Ultra perfectly embodies a great camera held back by software — the HyperOS interface is seriously lagging and not up to par with the rest of the phone.
• Android Police's verdict: the best camera phone of 2026 has a serious problem.
• Camera-app software limitations frustrated reviewers — quick-launch buried in gesture settings and the ultrawide preview looking awful.
• After 3 months one owner called HyperOS 3 one of the best versions of Xiaomi software they've used, with 6 years of security support.
• Even fans note HyperOS hasn't visibly evolved in years and Xiaomi should work on the software more.

Motorola Razr Fold

At $1,899 it undercuts the Z Fold 7 and is the only premium book foldable many US buyers can actually purchase — value hinges on whether the non-Elite chip and update questions matter to you.

• At $1,899.99 / £1,799.99 it undercuts the Galaxy Z Fold 7 by about $100/£100, and the pre-order Moto Pen Ultra bundle adds real value — the sum of its parts is the best foldable on the market.
• If you're tired of Samsung-only or have no interest in the Pixel Fold, this may be the best folding phone you can get in the US right now — the Oppo Find N6 and Honor Magic V6 aren't available there.
• It could be called a disappointment, especially compared to the Samsung Galaxy Z Fold and Honor Magic V5 — it should have offered something more compelling to stand out.
• If Motorola drops the price by even two or three hundred dollars within the first few weeks, this phone suddenly becomes a much stronger contender.
• It competes fairly well with the Oppo Find N6, which is amazing to see.

Xiaomi 17 Ultra

A premium price for a premium camera. Reviewers agree the hardware is exceptional but increasingly question whether the global price and software make it the right buy versus the cheaper Xiaomi 17 or rivals.

• The 17 Ultra starts from £1,299 / €1,499 (about $1,750) globally, with the limited Leitzphone at £1,699 / €1,999 ($2,300) — right up there with high-end Pixel and Galaxy models.
• The 17 Ultra is getting all the attention as a camera-focused device with best-of-the-best specs, but most buyers are likely considering something closer in price to the standard Xiaomi 17.
• The Xiaomi 17 Ultra's value proposition has weakened compared to the previous generation, though at a discounted price it suddenly becomes excellent value.
• Tech Advisor argues the standard Xiaomi 17 actually comes out ahead for most people — bigger 6,330mAh battery, 35+ hours video playback and faster 100W charging.
