Samsung Galaxy Z Flip 7 vs Motorola Razr Ultra (2025)

The Samsung Galaxy Z Flip 7 and Motorola Razr Ultra (2025) are the two flagship clamshell foldables competing for the same pocket. Samsung's entry starts at $1,099.99 and positions itself as the more mainstream option, leaning on Samsung's established foldable ecosystem and a refined, iterative design. Motorola's Razr Ultra comes in $200 higher at $1,299.99, pushing harder on specs across the board: bigger battery, faster charging, higher-resolution outer display, and a Snapdragon 8 Elite chip paired with 16GB of RAM.

The Galaxy Z Flip 7 is the stronger phone for biometrics, speakers, microphone quality, and data transfer speeds, and it edges ahead on camera performance overall. The Razr Ultra counters with a faster processor, substantially quicker charging, a sharper inner display, and better video battery life. Their overall scores land close together, with the Razr Ultra slightly ahead. Neither phone dominates the other, and the $200 price gap makes the choice more interesting than the raw scores suggest.

Here’s how the Samsung Galaxy Z Flip 7 and the Motorola Razr Ultra (2025) compare in our testing.

Design

Both phones are aluminum-framed clamshell foldables with IP48 ratings, which means they're rated for dust particles larger than 1mm and submersion in freshwater up to a manufacturer-specified depth. Neither achieves the IP68 rating common on slab flagships, so neither is rated for pressurized water or extended submersion.

The Galaxy Z Flip 7 folds down to 85.5 x 75.2 x 13.7mm and opens to 166.7 x 75.2 x 6.5mm. It weighs 188g. The inner screen is protected by plastic (typical for foldables), while the outer cover and back use Gorilla Glass Victus 2. The Razr Ultra is a bit thicker and heavier: 88.1 x 74 x 15.7mm folded, 171.5 x 74.0 x 7.2mm unfolded, at 199g. Its inner display uses Gorilla Glass Ceramic, and the back comes in vegan leather, Alcantara, or wood finishes rather than glass. That 11g weight difference is minor, but the Razr Ultra is 2mm thicker when folded, which you'll notice in a front pocket.

The Z Flip 7's inner display has an 86.2% screen-to-body ratio with a 21:9 aspect; the Razr Ultra's inner screen is slightly larger at 7 inches with 87.3% screen-to-body and a taller 22:9 aspect. The outer displays differ more significantly in usable area and resolution, which we'll cover in the display section. Bandicoot Lab doesn't formally test design or durability, so all observations here are based on published specifications.

Display

Inner

The Razr Ultra's 7-inch inner display runs at 1080 x 2640 resolution, giving it 464 pixels per inch. The Z Flip 7's 6.8-inch panel is 1080 x 2520 at 397 PPI. You'd need to look closely to see the density difference, but text rendering is a touch crisper on the Razr Ultra. The Razr Ultra also supports up to 165Hz refresh, compared to 120Hz on the Z Flip 7.

Manual brightness favors Samsung. The Z Flip 7 reaches 690 nits with the slider maxed out; the Razr Ultra tops out at 501 nits. That gap matters outdoors when auto-brightness isn't engaged or when you want manual control. In HDR content, the two are closer: the Z Flip 7 peaks at 2,785 nits and the Razr Ultra at 2,850 nits. How well each display maintains brightness as bright areas within the image get larger is similar, with the Z Flip 7 at 54.8% and the Razr Ultra at 57.3%. Both displays hold their brightness well over sustained 30-minute HDR playback, with the Z Flip 7 at 98.7% stability and the Razr Ultra at 99.1%.

Color accuracy in their best modes is close. Both displays track sRGB well, with the Z Flip 7's Natural mode covering 99.4% of sRGB and the Razr Ultra's Radiant mode covering 96.8% of Display P3. The Z Flip 7's best color accuracy mode produces colors that are tight and consistent, with no individual patch drifting far from reference. The Razr Ultra's best mode averages slightly better overall, but its worst individual patches drift further from target, meaning you'll occasionally see a color that's clearly off even though the average looks good.

For HDR tone mapping, the Z Flip 7 renders HDR content faithfully with a mild brightness boost and starts clipping highlights at 75% of the PQ input range. The Razr Ultra holds highlights longer before clipping at 85%, which means more detail in very bright HDR scenes, but its overall tracking of the HDR reference curve is less precise. Touch latency is 18.6ms on the Z Flip 7 and 19.9ms on the Razr Ultra — a difference you won't feel.

Outer

The outer displays diverge more sharply. The Razr Ultra's 4-inch cover screen runs at 1080 x 1272 (417 PPI) with a 1-165Hz refresh rate. Samsung's 4.1-inch outer panel is 948 x 1048 (342 PPI) at 60-120Hz. The Razr Ultra's cover screen is denser, smoother, and closer to what you'd expect from a standalone small phone display.

The Z Flip 7's outer display is considerably brighter manually at 453 nits and peaks at 2,599 nits in HDR — high for a cover display.

Color accuracy on the cover screens differs. The Razr Ultra's outer display is well-calibrated — colors are accurate and neutral across the board with minimal drift. The Z Flip 7's outer panel is decent but less precise, with colors skewing slightly from target. For quick interactions, this doesn't matter much, but if you're composing photos using the cover screen as a viewfinder, the Razr Ultra gives you a more trustworthy color preview.

HDR tone mapping on the Z Flip 7's outer display tracks the reference curve closely with minimal boost and clips at 80% of the input range. Both outer displays hold brightness well over time, with the Z Flip 7 at 98.8% sustained stability.

Performance

The Galaxy Z Flip 7 runs Samsung's Exynos 2500 with 12GB of RAM. The Razr Ultra uses Qualcomm's Snapdragon 8 Elite with 16GB. The extra 4GB of RAM on the Razr Ultra helps with keeping apps in memory during multitasking.

CPU performance gives the Razr Ultra a clear lead. It scores 2,917 single-core and 8,917 multi-core in GeekBench 6, compared to the Z Flip 7's 2,322 single-core and 8,162 multi-core. That's roughly a 26% single-core advantage and a 9% multi-core advantage. In practice, the single-core gap shows up in app launch times and responsiveness; the multi-core gap is smaller and less likely to be felt day to day.

GPU performance is where the Razr Ultra pulls further ahead. Its peak Wild Life Extreme score of 6,375 beats the Z Flip 7's 5,387 by about 18%. More importantly, the Razr Ultra maintains 68.1% stability through the stress test versus just 44% for the Z Flip 7. The Z Flip 7 throttles harder under sustained GPU load — during long gaming sessions, it'll drop to noticeably lower frame rates than where it started. The Razr Ultra runs hotter (50°C versus 41.6°C at peak) but maintains performance better. Solar Bay results tell the same story: similar peak scores (11,372 vs 11,356) but the Z Flip 7 drops to 44.2% stability while the Razr Ultra holds 66.6%.

Browser performance reverses the gap entirely. The Z Flip 7 scores 26.5 in Speedometer compared to the Razr Ultra's 19.4 — a 37% advantage that you'll feel during complex web page interactions.

Camera

Both phones carry 50 megapixel main cameras with similar sensor sizes and apertures. Neither has a telephoto lens. The Z Flip 7 pairs its main with a 12 megapixel ultrawide and a 10 megapixel front camera; the Razr Ultra uses 50 megapixel sensors for both its ultrawide and front camera. The Razr Ultra's higher-resolution secondary cameras show up clearly in front camera sharpness. The Z Flip 7 scores higher overall for camera performance, pulled up by better color accuracy on its main lens and stronger dynamic range from the ultrawide.

At deep zoom levels, both phones struggle — which is expected without a telephoto lens. The Z Flip 7 retains moderate detail at 10x (its maximum digital zoom), while the Razr Ultra can push to higher zoom levels but with heavy softness. Neither is a substitute for optical zoom.

Both phones produce a slightly vivid look by default, with saturation pushed modestly above neutral in bright light. The Z Flip 7 leans a touch warmer overall; the Razr Ultra is closer to neutral saturation in mid-light but shifts significantly in low light, which we'll detail below.

Main

The Razr Ultra's main camera resolves more detail than the Z Flip 7 in bright and mid-light conditions. The Z Flip 7 holds its sharpness well as light drops, while the Razr Ultra's detail falls off substantially in dark conditions.

Color character differs between the two. The Z Flip 7's main camera pushes saturation about 13–14% above neutral across lighting conditions, giving photos a consistently vivid look. The Razr Ultra is more restrained in bright light, sitting closer to accurate saturation, and nearly neutral in mid-light. In low light, the Razr Ultra's processing shifts hard toward magenta-red, with severe hue errors. This appears to be driven by a white balance overcorrection under warm light — the processing aggressively pushes colors in a way that makes warm-lit scenes look unnatural. The Z Flip 7 also shifts toward warm tones as light drops, but the effect is considerably milder. Skin tones on the Z Flip 7 drift moderately from reference across all lighting; on the Razr Ultra, skin tones are slightly more accurate in bright light but worse in the dark.

Dynamic range on the main camera favors the Galaxy Z Flip 7. High-contrast scenes retain more shadow detail and highlight separation. The Razr Ultra’s main camera clips highlights earlier, which can flatten bright skies or lose detail in light sources. Both cameras clip highlights to some degree, but the Razr Ultra preserves more usable range in challenging scenes. Video stabilization is better controlled on the Z Flip 7, with less residual shake in handheld footage.

Ultrawide

The Z Flip 7's 12-megapixel ultrawide and the Razr Ultra's 50-megapixel ultrawide take different approaches. The Razr Ultra resolves solid detail across lighting conditions, maintaining good sharpness even in low light. The Z Flip 7's ultrawide also performs well for sharpness, and its dynamic range is strong — it pulls more detail from shadows and highlights than its own main camera.

Color on the Z Flip 7's ultrawide follows the same vivid tuning as the main lens, with saturation bumped up across the board. In low light, hue accuracy degrades significantly, with a strong magenta shift appearing — a white balance correction issue, as the bias swings dramatically under warm lighting. The Razr Ultra's ultrawide handles color more consistently across lighting conditions. Hue errors are lower and more stable as light changes, and saturation stays closer to neutral. The Razr Ultra's ultrawide produces more reliable colors in mixed and low light than the Z Flip 7's.

Dynamic range on the Razr Ultra's ultrawide is broader, with more visible gradation between shadows and highlights, though it does clip highlights. The Z Flip 7's ultrawide also clips highlights but retains good overall scene depth.

Front

The Razr Ultra's 50-megapixel front camera is significantly sharper than the Z Flip 7's 10-megapixel sensor in all lighting conditions. In bright light, the difference is large, and it persists into mid and low light. If selfie quality matters to you, this is one of the biggest gaps between the two phones.

Color accuracy on the front cameras is poor on both phones, but in different ways. The Z Flip 7's front camera produces vivid, slightly warm shots in good light, then shifts dramatically toward magenta in low light — a white balance issue that makes faces look ruddy and unnatural under warm indoor lighting. Skin tones are consistently far from accurate across all conditions. The Razr Ultra's front camera desaturates rather than oversaturates, producing muted, slightly washed-out colors, especially in mid-light. Skin tones are also inaccurate, drifting warm with a yellow cast in bright light. Neither front camera produces reliable skin tones: the Z Flip 7 oversaturates and shifts pink, while the Razr Ultra undersaturates and shifts yellow.

Dynamic range from the Razr Ultra's front camera is broader, holding more detail in both shadows and highlights. Video stabilization is better on the Razr Ultra's front camera as well, with less jitter in handheld video. The Z Flip 7's front camera shows more instability during movement.

Battery

The Razr Ultra carries a 4,700mAh battery; the Z Flip 7 has a 4,300mAh cell. That 400mAh gap translates to a meaningful difference in video playback. On the inner screen at 200 nits, the Razr Ultra lasts 29.7 hours versus the Z Flip 7's 28.4 hours. On the outer screen, the gap widens: 32.8 hours for the Razr Ultra versus 24.7 hours for the Z Flip 7. For context, 29–30 hours of video playback on the inner display means you could comfortably get through two full days of mixed use before charging either phone.

Web browsing drain over five hours is nearly identical: 22% on the Razr Ultra and 23% on the Z Flip 7. Standby drain is the same at 3% over eight hours. The real divergence is gaming. The Z Flip 7 drains 21% during the one-hour gaming stress test; the Razr Ultra burns through 43% — more than double. This tracks with the performance: the Razr Ultra's Snapdragon 8 Elite pushes harder and runs hotter under GPU load, and the battery pays for it. If you game frequently on your phone, the Z Flip 7 will last substantially longer per session despite having the smaller battery.

Charging

Charging speed is one of the widest gaps between these two phones. The Razr Ultra supports 68W wired charging; the Z Flip 7 tops out at 25W. At 10 minutes, the Razr Ultra reaches 30% versus 20% on the Z Flip 7. At 30 minutes, it's 75% versus 55%. That 20-percentage-point gap at the half-hour mark means the Razr Ultra can recover enough charge for a full evening out in the time it takes to shower and get ready.

Wireless charging follows the same pattern. The Razr Ultra's 30W wireless charging reaches 12% in 10 minutes and 29% in 30 minutes, compared to the Z Flip 7's 15W wireless at 7% and 19% respectively. If you rely on wireless charging overnight, neither phone will have trouble hitting full by morning. For quick wireless top-ups during the day, the Razr Ultra gets meaningfully more juice in less time.

Speaker

The Z Flip 7's speaker system is louder and cleaner than the Razr Ultra's. It hits 77.2 dBA maximum volume versus the Razr Ultra's 72.8 dBA — a noticeable difference in a room. Distortion is also lower on the Z Flip 7 at 5.35% average THD compared to nearly 10% on the Razr Ultra, which means the Z Flip 7 stays cleaner as you push the volume up. The Razr Ultra starts to sound rough at high volume where the Z Flip 7 still sounds composed.

Both phones have limited bass, which is typical for thin foldables, but the Z Flip 7 has fuller low-end than the Razr Ultra. The Z Flip 7 also has slightly better high-frequency clarity. The Razr Ultra's speaker sounds thinner overall and more strained at volume. For speakerphone calls and casual media playback, the Z Flip 7 is the better choice; for anything where audio quality matters, you'll want headphones with either phone.

Microphone

The Z Flip 7's microphone performs well, with consistent frequency response and low deviation across the range. It's one of the better microphones we've tested. The Razr Ultra's microphone is above average but not as flat or consistent, with slightly more variation across frequencies. For voice calls and video recording, both phones capture clear audio. The Z Flip 7 has a small edge in accuracy that might matter for voice memos or content creation.

Other

Fingerprint unlock speed favors the Z Flip 7 at 121ms average versus 165ms on the Razr Ultra. Both use capacitive sensors. The Z Flip 7's unlock is snappy and immediate; the Razr Ultra's is fine but has a perceptible pause. Neither phone has hardware-based face unlock.

Data transfer speeds are dramatically different, and this comes down to ports. The Z Flip 7 uses USB-C 3.2, delivering read speeds of 173 MB/s and write speeds of 171 MB/s. The Razr Ultra is limited to USB-C 2.0, which caps it at 39 MB/s read and 36 MB/s write — roughly a quarter of the Z Flip 7's throughput. If you transfer files to a computer with any regularity, this is a real bottleneck on the Razr Ultra.

Storage options: the Z Flip 7 comes in 256GB and 512GB configurations, while the Razr Ultra starts at 512GB and goes up to 1TB.

Conclusion

These two phones trade wins across nearly every category. The Galaxy Z Flip 7 is the better choice if you prioritize speakers, microphone quality, fast fingerprint unlock, USB transfer speeds, camera color consistency, and gaming battery efficiency. It's also $200 cheaper. The Razr Ultra wins on raw processor and GPU performance, charging speed (by a wide margin), front camera sharpness, main camera dynamic range, inner display resolution and refresh rate, and video playback endurance.

The Z Flip 7's weaknesses are its slow charging, lower GPU sustained performance, and less detailed front camera. The Razr Ultra's weak points are its loud but distorted speakers, USB 2.0 data speeds, heavy gaming battery drain, and severe color shifts in low-light photography. Both phones have mediocre low-light front camera color, so neither is great for indoor selfies under warm lighting.

If you want the phone that charges fastest, has the sharper selfie camera, and delivers the most sustained GPU power for gaming (even if it drains faster doing it), the Razr Ultra justifies its premium. If you want a more complete package at a lower price — better speakers, more reliable camera color, faster data transfer, and longer gaming sessions per charge — the Z Flip 7 is the more balanced buy.
