Motorola Razr Fold vs OnePlus 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.

OnePlus 15

The most divisive part of the phone. OnePlus ended its 5-year Hasselblad partnership and moved to smaller in-house-tuned 'DetailMax' sensors: a triple 50MP wide + ultrawide + 3.5x telephoto. Some reviewers rate the results among the best camera phones; many call it a regression from the OnePlus 13 with color-accuracy and high-zoom issues.

• OnePlus's 5-year Hasselblad partnership has ended and the rear sensors are smaller than the OnePlus 13's — every rear camera sensor is smaller, which doesn't bring joy.
• The camera is consistently inconsistent — a recurring theme across reviews of this phone's imaging.
• The photos were usually just as good as the best camera phones, and in some cases the OnePlus 15 shots were the best compared to the Pixel 10 Pro and Galaxy S25 Ultra — and it's the best camera phone tested for fast-moving subjects.
• It has three 50MP rear cameras (wide, ultrawide, 3.5x optical telephoto); both it and the iPhone 17 Pro are impressive zoom shooters, but the iPhone is the obvious selfie winner.

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.

OnePlus 15

Snapdragon 8 Elite Gen 5 with up to 24GB RAM and a custom tri-chip setup — it tops benchmark charts, beats the iPhone's A19 in multi-core and runs games at up to 165fps. The asterisk is sustained thermals: day-to-day it stays cool, but extended stress benchmarks repeatedly overheat and shut down.

• Across a benchmark suite the OnePlus 15 performed 19–22% better than the OnePlus 13 and 14–19% better than the S25 Edge, and outperformed the OnePlus 13 by 10% in the stress test.
• Geekbench shows the Snapdragon 8 Elite Gen 5 easily beating the A19 with a multi-core score over 11,000; in Genshin Impact it averaged 119fps vs the iPhone 17's 107fps over 30 minutes, running cooler at under 36°C.
• BGMI runs native 120fps (165fps with frame interpolation) at under 35°C and under 4W power draw, making it one of the best phones for gaming with its 165Hz panel and bypass charging.
• In a 15-minute 20-thread CPU throttle test it throttled to 82% of max performance at a controlled 34–35°C with only 3% battery drain.
• It flashed an overheating warning after barely 8 minutes of a peak-load benchmark, shutting it down and disabling the flashlight and hotspot — though in day-to-day use it runs smoothly with only moderate warmth.

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.

OnePlus 15

The single biggest reason to buy this phone. A 7,300mAh silicon-carbon cell delivers the best smartphone battery life ever measured — a record ~25-hour drain test and 2–2.5 days of real use — with 120W wired charging refilling it in ~40–51 minutes plus 50W wireless.

• The OnePlus 15 lasted an insane 25 hours 13 minutes in the drain test — officially the best phone for battery life, beating the iPhone 17 Pro Max's 17h54m and lasting over 10 hours longer than the Galaxy S25 Ultra.
• The OnePlus 15 just delivered the best battery life we've ever measured — a very, very good phone and a strong value pick for late 2025.
• In real use it averaged 2 days 11 hours on a full charge, and 7–8 hours of screen-on time is effortless thanks to the 7,300mAh cell and aggressive standby management.
• 120W SuperVOOC charged 1→50% in 22 minutes, 75% in 36 minutes and a full 1→100% in 51 minutes; other tests hit a full charge in roughly 40–43 minutes.
• It also keeps 50W AirVOOC wireless charging — about 30% in 30 minutes and ~85% in 92 minutes, with the device staying cool around 34–35°C.

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.

OnePlus 15

OxygenOS 16 on Android 16 — clean and fast, and a clear AI redemption after the OnePlus 13: Plus Mind (via the new plus key), AI Eraser, plus Google's Gemini Live and Circle to Search. The reservation is the 4-year OS / 6-year security commitment and the lingering uncertainty over OnePlus's regional operations.

• OnePlus redeems the OnePlus 13's lack of AI with OxygenOS 16 — AI Eraser, the Pixel-Screenshots-like Plus Mind via the dedicated plus key, plus Gemini Live and Circle to Search.
• Under all the AI trends OxygenOS still feels like OxygenOS — clean, light and more customisable than a Pixel, with one of the best dark-icon implementations in the segment.
• OnePlus commits to 4 years of major Android updates and 6 years of security patches — not elite, but solid for a phone at this price, though it trails Google and Samsung's 7 years.
• OnePlus does its usual ~1-month post-launch update that fixes some camera issues, and despite overheating reports two reviewers couldn't get their units to overheat in normal use.

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.

OnePlus 15

At $899 (12/256) / $999 (16/512), the OnePlus 15 undercuts the $1,000+ Pixel 10 Pro XL, Galaxy S26 Ultra and iPhone 17 Pro Max while matching or beating them on battery, performance and charging. The recurring caveat: it's an outstanding-value flagship that camera-focused buyers may still pass on.

• OnePlus has gone from flagship killer to flagship — available for $899 (12/256) or $999 (16/512).
• It's not trying to be better than everything else — it's trying to be the best phone for $899, and it absolutely nails that, even if cameras are a bit of a letdown.
• I'll just call it the best phone you can buy and the first phone I have tested that deserves a perfect score — OnePlus's best phone, not a step down.
• The honest counterpoint: I'm not angry at the OnePlus 15, I'm just disappointed — the camera and identity sacrifices undercut an otherwise excellent phone.
• From a US perspective the performance and longevity make it a fantastic value compared to the much more expensive $1,000–1,200 offerings from Google, Samsung and Apple — the 'downgrades' are mostly hair-splitting.
