Motorola Razr Fold vs Xiaomi 15

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 15

A Leica-tuned triple 50MP system that reviewers rate among the best you can get in a compact phone, with a large 1/1.3-inch main sensor and a versatile 60mm telephoto. Pro-grade video is strong via the main sensor.

• This is one of the best and most capable camera setups you can currently get in a relatively compact phone.
• Xiaomi swapped the Xiaomi 14 sensor for a new JN5 telephoto with a 60mm focal length, paired with a large 1/1.3-inch main sensor.
• The telephoto offers 2x optical zoom (46mm) but you can still push to ~6x with an impressive level of detail — a strong pick for buyers who don't need extreme reach.
• Portrait shots were compared directly against a Sony a6100 with a 23mm f/1.4 lens (≈35mm equivalent, ~f/2.1 depth of field) and held up well.
• The main camera can shoot 8K30 from the main sensor, and that 8K footage is roughly 50% more detailed than 4K30.

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

Snapdragon 8 Elite makes it one of the fastest small phones available, and it holds sustained performance better than larger rivals — but it still runs warm under prolonged synthetic and 4K-video loads.

• It runs the Snapdragon 8 Elite — pretty much the fastest chipset available on any smartphone at launch.
• In a stress test against the Galaxy S25 and Oppo Find X8, the Xiaomi 15 won on stability (~72%) versus the S25's 67% and the Find X8's 58.6%, and also had the upper hand in Geekbench.
• Despite being a much smaller phone tested in hotter conditions, it sustained better performance and smoothness than an iQOO 13 in a 10-loop benchmark; an external cooler lifted the lowest-loop score 14%.
• The chipset swap to the Snapdragon 8 Elite is welcome, but just like last year the Xiaomi 15 still struggles to keep it cool under prolonged loads.
• A year on the flagship chipset is still very powerful and the phone's performance remains solid in 2026.

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 15

A ~5,240mAh cell that beats a Galaxy S25 in head-to-head rundowns and recharges very fast over both wire and wireless — though a HyperOS idle drain divides reviewers.

• The Xiaomi 15 packs a larger ~5,240mAh battery versus a Galaxy S25's ~4,000mAh while only being 27g heavier, and ended a head-to-head rundown at 30% vs the S25's 13%.
• It charges in around 45 minutes with the 90W adapter in the box, and the reviewer had zero issues with battery life in normal mixed use.
• From a fully dead battery a measured charge test reached 66% in 45 minutes, 91% at 1h05m and a full 100% in about 1h15m.
• It also supports 50W wireless charging — faster than typical flagship wired speeds — though there are no Qi magnets built in, so you need a 50W-compatible mat for top speed.
• Xiaomi says battery can run roughly 25% longer than the Xiaomi 14.

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 15

HyperOS is fast and feature-rich (IR blaster, long update commitment) but the bloat, ads and unremovable apps remain the phone's most consistent complaint, and big updates have shifted benchmark behaviour.

• Xiaomi committed to roughly 4 years of major Android OS updates and 5 years of security patches.
• Owners dislike that certain pre-installed apps can't be uninstalled and that HyperOS surfaces ads and unsolicited notifications even on a flagship.
• The HyperOS 3 (Android 16) update is described as one of the riskiest software moves Xiaomi has made; everything still feels like butter day-to-day but Geekbench scores have declined with every major HyperOS update.
• After the Android 16 / HyperOS 3 update many owners report better battery life, and the IR blaster remains a favourite Xiaomi touch.
• A year on the software support has kept the phone feeling fresh and reliable, with a smooth overall experience.

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 15

Widely called the best compact flagship of 2025, but it's priced like a flagship and only an iterative bump over the Xiaomi 14 — and in the US a Galaxy S25 or iPhone 16 is cheaper and easier to buy.

• One of the best compact flagships on the market, if not the best one — reviewers were left quite impressed.
• Pitched directly as 'The Best Compact Flagship of 2025?' in a benchmarks-and-blind-camera comparison against the iPhone 16 Pro Max and Galaxy S25 Ultra.
• A compact flagship with excellent battery life, though it shares near-identical design, display and cameras with its predecessor — it can feel like a fairly minor update.
• A new Xiaomi 15 (12GB/256GB) retails around €999 globally; used prices have dipped to €700-800 on eBay/Swappa — a solid 20-30% drop that makes the used market tempting.
• Compared with a Galaxy S25 or iPhone 16 — both cheaper and easier to buy in the US — the Xiaomi 15's price feels premium for what is essentially an iterative upgrade over the Xiaomi 14.
