We're in the middle of a thin phone renaissance. Samsung's teasing the Galaxy S25 Edge, Apple's rumored iPhone Air has everyone buzzing, and now Motorola's thrown their hat in the ring with the Edge 70 (also sold as the Moto X70 Air in China).
But here's the question nobody's asking: When every flagship is racing to be the thinnest, does "thin" actually mean "better"?
I've spent weeks with the Motorola Edge 70, and I'm ready to give you the unfiltered truth about this ultra-slim smartphone. Spoiler alert: There are some genuinely impressive engineering feats here, but also a few head-scratching compromises.
Let's dive deep.
The Numbers That Matter: Just How Thin Are We Talking?
6.6mm thick. 159 grams.
To put that in perspective, that's thinner than two credit cards stacked together and lighter than most modern smartphones by 30-40 grams. You absolutely notice this the moment you pick it up.
But here's what shocked me: Despite these incredibly slim dimensions, Motorola managed to squeeze in a 4,800mAh battery. That's not some tiny compromise battery—that's legitimately competitive with phones twice as thick.
Add to that a large high-resolution screen, the new Snapdragon 7s Gen 4 chipset, and solid cameras, and you start wondering what kind of engineering wizardry is happening inside this thing.
Design: Where the Edge 70 Actually Stands Out
Look, I've tested a lot of "thin and light" phones over the years, and most of them feel like handling glass plates—sleek but terrifyingly slippery.
The Motorola Edge 70 is different.
The Grippy Back Panel Game-Changer
That textured back panel isn't just a design flourish—it's genuinely functional. The subtle texture gives you actual grip without feeling rough or cheap. I can confidently use this phone one-handed without that constant fear of it slipping out of my palm.
Is it the absolute thinnest phone on the market? Technically, no. There are a couple of devices that beat it by literal fractions of a millimeter. But those phones feel like they'll shatter if you breathe on them wrong.
Built Tougher Than It Looks
This is where Motorola earns serious respect points:
- Aluminum frame (not plastic pretending to be premium)
- US Military Standard MIL-STD-810H certified for humidity, temperature extremes, and shock resistance
- IP68 rating against dust and water submersion
- IP69 rating against high-pressure heated water jets
That IP69 rating is wild—it means this phone can handle industrial cleaning scenarios with pressurized hot water. When's the last time you needed that? Probably never. But it speaks to the build quality.
Pantone Colors (Because Motorola Gonna Motorola)
The color options come courtesy of Pantone, which is typical Motorola branding at this point. I have the green variant, and it's subtle enough to not scream "look at me" but interesting enough to not be boring.
Interestingly, the default UI theme matches the phone color—green phone gets green quick toggles and accents. It's a nice touch that shows attention to detail.
That Dedicated AI Button: Innovation or Annoyance?
There's a physical AI key on the side of this phone, and you can't reassign it to anything else.
Let that sink in. A hardware button permanently dedicated to AI functions that you cannot customize for other shortcuts.
Your mileage will vary on this. If you're deep into AI assistants and features, it might be convenient. If you're like me and occasionally use AI but don't need a dedicated button for it, this feels like wasted potential.
What I would have preferred: The ability to remap this to camera launch, flashlight, voice recorder, or literally any customizable shortcut.
What Motorola decided: Nope, AI only.
We'll talk more about the AI features later, but this hardware decision is definitely polarizing.
Display: Bright, Sharp, and Smooth
The 6.7-inch OLED panel with 1220p resolution delivers:
- 446 PPI (text is incredibly sharp)
- 120Hz refresh rate (smooth scrolling and animations)
- Gorilla Glass 7i protection (not the latest Victus, but solid)
- 10-bit color depth (over a billion colors)
- HDR10+ support for compatible video content
Brightness That Handles Sunlight
Peak brightness hit over 1,450 nits in automatic brightness mode with HDR content. That's legitimately flagship-tier brightness.
In practical terms, this means you can actually see your screen in direct sunlight without squinting and shielding it like you're trying to read ancient scrolls.
Refresh Rate Behavior: Smart But Not Adaptive
The 120Hz refresh rate drops to 60Hz when the screen is idle to save battery. This is smart, but there's no LTPO technology here.
What does that mean? LTPO allows for variable refresh rates (like 1Hz when showing a static image, ramping up to 120Hz when scrolling). Without it, you're stuck with just two modes: 120Hz active, 60Hz idle.
It's not a dealbreaker, but it does mean slightly less battery efficiency compared to flagship phones with LTPO displays.
Audio: Loud But Not Particularly Rich
Stereo speakers earned a "very good" mark in loudness testing, which is great for media consumption and speakerphone calls.
Sound quality is... average. Highs are crisp, there's some bass presence, but vocals and mids feel hollow and need more body.
For casual YouTube watching or social media scrolling, it's fine. For music appreciation or serious movie watching, you'll want headphones.
Storage Situation: A Puzzling Downgrade
Here's where things get weird: No microSD card slot.
Last year's Edge 60 had expandable storage. This year? Nope. You're stuck with either 256GB or 512GB internal storage.
But wait, it gets stranger: The storage has been downgraded from UFS 4.0 to UFS 3.1.
UFS 4.0 is significantly faster for read/write operations. Why would Motorola downgrade this in the newer model? Cost-cutting? Space constraints in the ultra-thin chassis?
Whatever the reason, it's a step backward that most reviews gloss over. I'm calling it out because if you're a power user who moves large files or plays storage-intensive games, you'll notice the difference.
Biometrics: Fast Fingerprint, Reliable Face Unlock
Optical in-display fingerprint scanner that's fast and reliable. My only complaint? It could be positioned slightly higher on the screen. When holding the phone naturally, I sometimes have to stretch my thumb down to reach it.
Face unlock works well in good lighting but struggles in dim conditions (typical for camera-based face recognition without dedicated IR sensors).
Software: Hello UI on Android 16
Motorola's Hello UI is one of the cleaner Android skins out there. If you've used recent Moto phones, you'll feel immediately at home.
The Moto App Hub: One-Stop Customization
All of Motorola's custom features live in the Moto app hub, organized into neat categories:
- Gestures and shortcuts
- Display customizations
- Gaming mode settings
- Connectivity options
Moto Unplug: Digital Wellbeing Done Right
This feature helps you take intentional breaks from social media and notifications. It's more nuanced than just "Do Not Disturb"—you can set specific times, apps, and behaviors.
In an era where every tech company pays lip service to digital wellbeing while simultaneously engineering their apps for maximum addiction, I appreciate Motorola actually building helpful tools here.
Smart Connect: Your Phone as a Desktop
Wirelessly or via cable, you can connect the Edge 70 to:
- Your PC for file sharing and notifications
- A tablet for extended screen real estate
- An external display to use it as a mobile desktop
The desktop mode is surprisingly functional. Not "replace your laptop" functional, but definitely "get work done in a pinch when traveling" functional.
The AI Situation: More Choice, Less Focus?
This is where Motorola's approach gets interesting—and maybe a bit scattered.
Instead of forcing you into one AI ecosystem, you get multiple AI assistants:
Microsoft Copilot (with Vision)
Accessible via that dedicated AI button, Copilot Vision works like Google's Gemini Live. You can have conversations with it, show it things through your camera, and ask context-aware questions.
Perplexity AI
Both as a standalone chatbot app and a context-sensitive "Explore with Perplexity" feature that deep-dives into whatever content you're viewing.
Moto AI (Motorola's Own)
Their proprietary AI assistant with its own search functionality.
Google Gemini and Gemini Live
Because of course Google's AI is here too.
The problem? Having four different AI assistants feels like too many cooks in the kitchen. Each one is competent, but which one do you actually use? The choice paralysis is real.
Specific AI Functions Worth Noting
When you press that AI key, you get access to:
Catch Me Up: Summarizes all your notifications into one digestible update. Actually useful when you've been away from your phone and come back to 50+ notifications.
Image Studio: AI-generated images, stickers, and avatars. Fun to play with, limited practical use.
Playlist Studio: AI creates music playlists based on your mood or description. Works better than expected.
Pay Attention: Records, transcribes, and summarizes audio. Fantastic for meetings, lectures, or interviews. This is genuinely useful.
Remember This: Quick note-taking that the AI organizes and uses to personalize future responses. Interesting concept that needs time to prove its value.
Software Support: Vague But Probably Good
Four years of major Android updates promised, which is solid but phrased vaguely.
Last year's Edge 60 got a guarantee of three updates. This year gets four. That's progress, but I'd prefer clear language like "guaranteed updates through Android 20" rather than "four years."
Still, four years is competitive and shows Motorola taking longevity seriously.
Performance: Solid Mid-Range, Not Flagship
Here's where we need to set expectations properly.
The Snapdragon 7s Gen 4 is Motorola's big chipset change this generation, moving from MediaTek Dimensity to Qualcomm Snapdragon.
Benchmark Reality Check
In testing, the Edge 70 scores in upper mid-range territory. It's an improvement over last year's model, but it's nowhere near flagship chips.
Compared to actual ultra-thin flagships like the rumored iPhone Air or Galaxy S25 Edge (which will pack flagship silicon), the Edge 70 is significantly less powerful on paper.
But here's the thing: In daily use, the performance is solid and reliable.
Apps launch quickly, multitasking is smooth, social media scrolling is buttery, and even demanding games run well (just not at maximum settings with all effects enabled).
Thermal Management: Impressively Cool
During prolonged stress tests, the Edge 70 maintained high performance without thermal throttling. The thin chassis actually dissipates heat well.
I gamed for extended sessions and never experienced uncomfortable heat or dramatic performance drops. That's impressive engineering in such a slim form factor.
Battery Life: The Pleasant Surprise
Remember that 4,800mAh silicon-carbon battery I mentioned?
Active use score: 13 hours and 36 minutes.
For a phone this thin, that's genuinely impressive. Not industry-leading, but way better than you'd expect from something so svelte.
In real-world mixed use (social media, browsing, some gaming, navigation, photos), I consistently got through a full day with 20-30% remaining.
Heavy users might need a midday top-up, but moderate users will comfortably make it to bedtime.
Charging: Fast Wired, Finally Wireless
68W wired charging (same as last year):
- 0 to 85% in 30 minutes
- Full charge in 41 minutes
No charger included in the box, which is unfortunately standard now. You'll need Motorola's 68W TurboPower charger (or any USB-PD compatible fast charger) to hit these speeds.
Wireless charging support (NEW this year):
Last year's model didn't have wireless charging. This year does, but there's a catch.
To get maximum wireless charging speed, you need:
- A magnetic wireless charger
- The included magnetic case
It's basically MagSafe for Motorola. The case comes bundled, which is nice, but it does add thickness that somewhat defeats the ultra-thin purpose.
Camera System: The Telephoto Sacrifice
Rear cameras:
- 50MP main camera
- 50MP ultrawide with autofocus
Front camera:
- 50MP selfie camera
Noticeably missing: No telephoto camera.
Last year's Edge 60 had 3x optical zoom. Motorola cut it this year to maintain the slim profile. Something had to give, and that was the telephoto.
Main Camera: Mature and Reliable
Daytime photos from the main camera are excellent:
- 12MP output (pixel binning from 50MP sensor)
- Great detail with natural, true-to-life rendering
- Accurate colors without oversaturation
- Wide dynamic range without being aggressive
- Excellent skin tones and facial detail in portraits
The computational photography here feels mature—not trying to impress you with artificial pop, just delivering photos that look like what you actually saw.
Portrait mode bokeh is realistic and well-executed. Subject separation is clean, and the blur gradient feels natural.
Digital Zoom: Better Than Expected
Since there's no optical telephoto, all zooming is digital.
2x zoom photos are surprisingly solid:
- Minimal detail loss
- Maintained sharpness and color accuracy
- Good dynamic range preservation
- Low noise
You won't pixel-peep and think these are native resolution shots, but for social media and quick sharing, they're more than adequate.
People photos at 2x zoom also hold up well with only minor drops in global sharpness.
Night Photography: Impressive HDR Work
Low-light shots from the main camera are genuinely good:
- Plenty of resolved detail
- Effective noise reduction without smearing
- Pleasantly saturated colors
- Impressively wide dynamic range with maintained contrast
Night mode brightens everything significantly—maybe too much. It lowers contrast and actually reduces detail slightly in the pursuit of that "bright night" look.
I preferred the standard auto mode for most night shots. The balance felt better.
2x digital zoom at night is usable but shows noticeable detail loss compared to standard shots.
Ultrawide Camera: Surprisingly Competent
Daytime ultrawide photos deliver:
- Very good detail and sharpness
- Wide dynamic range
- Color consistency with the main camera (important!)
- Natural rendering with controlled noise
Autofocus on the ultrawide means you can shoot macro close-ups. Results are nice with good detail, excellent colors, and superb dynamic range.
Night ultrawide shots have impressive detail for this type of camera, with good colors, exposure, and dynamic range.
Night mode for ultrawide improves dynamic range and reduces blown highlights in certain scenes. Worth trying depending on conditions.
Selfie Camera: High-Resolution Excellence
The 50MP front camera produces very good selfies:
- Impressively detailed
- Natural facial features rendering
- Realistic skin tones and colors
- Plenty wide dynamic range
No overly smoothed skin or aggressive beautification by default. These look like actual photos of you, not Instagram filter versions.
Video Recording: Capable But Not Perfect
All three cameras support 4K video recording.
Main Camera Video (Daytime)
Excellent footage with good detail, low noise, accurate colors, and wide dynamic range.
Zoomed video gets noticeably noisier and shakier than I'd like. The lack of optical zoom hurts here more than in photos.
Ultrawide Video
Great detail, good colors and contrast, solid dynamic range. Very usable for vlogging or wide establishing shots.
Low Light Video
The main camera handles nighttime well—good dynamic range and colors, above-average detail, and low noise.
Stabilization: Room for Improvement
Video stabilization works but isn't class-leading. There's leftover shakiness and occasional wobbling effects, especially when walking.
It's not terrible, but flagship phones from Samsung and Apple do better here. For static or slow-panning shots, it's fine. For action or walking footage, you'll notice the limitations.
Who Should Buy the Motorola Edge 70?
Buy It If:
✅ You genuinely value thin and light design and the Edge 70's textured grip appeals to you
✅ You want excellent durability (IP68, IP69, MIL-STD-810H) in a slim phone
✅ Camera quality matters but you can live without optical zoom
✅ Good battery life in a thin package is a priority
✅ You like clean Android with useful customizations
✅ Fast charging is more important to you than all-day battery
✅ You'll actually use multiple AI assistants and features
Skip It If:
❌ You need flagship performance for demanding gaming or professional apps
❌ Optical zoom is essential for your photography
❌ You hate dedicated buttons that can't be remapped
❌ Top-tier video stabilization is critical
❌ You need expandable storage via microSD
❌ Price-to-performance ratio is your main buying criterion
The Price Problem: Great Phone, But...
Here's the uncomfortable truth: The Motorola Edge 70 doesn't come cheap, despite packing a mid-range chipset rather than flagship silicon.
At launch pricing, it's competing against phones with more powerful processors. That's a tough sell.
However, once the price settles down (and it will, as it always does with Moto phones), this becomes a much more compelling proposition.
If you can snag this during a sale or a few months after launch, the value equation changes significantly.
Final Verdict: The Best Ultra-Thin Phone for Most People
The Galaxy S25 Edge will likely be more powerful. The iPhone Air will probably be thinner and have better cameras. But both of those will cost significantly more.
The Motorola Edge 70 hits a sweet spot: genuinely thin and light design that doesn't feel fragile, excellent cameras for everyday use, solid battery life, fast charging, great durability, and clean software.
Is it perfect? No. The mid-range chipset at near-flagship pricing is questionable. The lack of optical zoom hurts. Video stabilization could be better. That non-remappable AI button is frustrating.
But as a complete package—as a phone you'll actually enjoy using every day—it succeeds more than it fails.
My recommendation: Wait for the price to drop 15-20% from launch, then seriously consider this as your next ultra-thin smartphone.
It's not trying to be the absolute best at any one thing. It's trying to be really good at everything while being remarkably thin and light.
And honestly? It mostly succeeds.
Alternative Ultra-Thin Phones to Consider
If the Edge 70 doesn't quite fit your needs, keep an eye on:
- Samsung Galaxy S25 Edge - More power, higher price
- iPhone Air (rumored) - Apple ecosystem, premium pricing
- Vivo X200 Lite - Alternative slim Android option
- Honor Magic V3 - If you want thin + foldable
