If you love big, overpowered phones, 2026 is your year. On one side, Samsung is lining up the Galaxy S26 Ultra, polished, pricey, and packed with new AI tricks. On the other hand, Xiaomi already swung first with the 17 Pro Max—wild battery, a playful second screen, and a price that makes rivals look… nervous. I’ve spent the week digging through specs, early hands-ons, and launch notes. Here’s the story, told like I’d explain it to a friend over coffee.
The Release Dance and Price Gap
Xiaomi blinked first: the 17 Pro Max launched in China in late 2025 and is set to roll out globally in early 2026. It came in hot with aggressive pricing—think “ultra phone without ultra price”. Meanwhile, Samsung’s S26 Ultra is expected to headline a January Unpacked, the company’s usual global spectacle with instant availability through carriers and retail partners.
And yes, the money bit matters. Samsung aims high—around the ultra-premium tier—because it sells the whole package: service centers, trade-in deals, updates, the lot. Xiaomi undercuts. That’s not a knock; it’s a strategy. If you’ve ever looked at a $1,300 phone and thought, “Do I really need to pay that?”, Xiaomi is basically whispering, “You don’t.”
Design & Display: Classic vs Bold
Both phones are huge—roughly 6.9-inch OLEDs with adaptive 120 Hz refresh. You’ll get inky blacks, brutal brightness, and the kind of clarity that makes you squint at your old phone like it betrayed you.
-
Samsung Galaxy S26 Ultra: Expect a near-bezel-less AMOLED with Samsung’s latest panel tech and anti-reflective glass. Rumors even point to an AI privacy filter that subtly narrows viewing angles so the stranger behind you can’t read your chat. Samsung may hide the front camera under the display for that uninterrupted sheet of glass look. The shape? Still “Ultra”—a bit boxy, premium, and purposeful. It’s the phone that looks like it means business because… it does.
-
Xiaomi 17 Pro Max: The front is all flagship. The back is where it gets brave: a 2.7-inch secondary OLED sits inside the camera island. It’s not just a gimmick. You can peek at notifications, switch tracks, check the weather, or—my favorite—use it as a rear selfie viewfinder so your TikToks and selfies use the main cameras. There’s even a retro gaming case that wraps physical buttons around that back screen. It’s playful. And honestly? Kinda awesome.
Think of it this way: Samsung kept the boardroom suit. Xiaomi showed up in a tailored jacket with neon lining.
Performance: Newest vs Nicest
Both are blazingly fast. Apps snap open, games run like butter, and multitasking feels frictionless.
-
Xiaomi ships with Qualcomm’s latest Snapdragon 8 Gen 5 (“Elite”), paired with up to 16 GB RAM/1 TB storage. That’s peak Android grunt right now.
-
Samsung is expected to run Qualcomm’s newest 8-series at launch too (with Exynos in some regions), plus Samsung’s usual optimizations. Real-world difference? Minimal for most people. Benchmarks might tilt to Xiaomi by a hair; everyday use won’t care.
If you’re the kind of person who watches GPU charts for fun, you’ll appreciate Xiaomi’s first-to-chip bragging rights. If you just want your phone to never stutter—both deliver.
Battery & Charging: A Landslide Win (for One)
This is where paths split.
-
Samsung S26 Ultra: ~5,000 mAh, now with 60 W wired charging. That’s finally quick by Samsung standards. Expect a solid full day plus a bit, and a much faster top-up than older Ultras.
-
Xiaomi 17 Pro Max: 7,500 mAh. Read that again. With 100 W wired and 50 W wireless. Xiaomi is chasing two-day battery life and actually reaching it. Plug in for a short coffee break and you’re basically done.
It’s not subtle—the Xiaomi wins endurance by a country mile. The only counterpoint: Samsung’s gentler charging may be kinder to battery health long-term. But if your priority is “don’t think about charging,” Xiaomi’s approach feels like freedom.
Cameras: Two Philosophies, Both Strong
There’s no bad camera here, just different flavors of “great”.
-
Samsung leans on its 200 MP main sensor plus multiple telephotos (including 5× periscope). Expect sharper zoom, brighter lenses than last year, and Samsung’s signature “wow” processing—punchy colors, clean stabilization, slick night shots. If Samsung goes under-display selfie, you’ll get the cleanest screen but probably softer selfies than a traditional hole-punch.
-
Xiaomi teams with Leica on a balanced 50 MP + 50 MP + 50 MP setup: wide, ultra-wide, and a 5× periscope that also focuses down to macro distances. That last bit is fun: you can shoot close-ups with telephoto compression and creamy background blur. Color science? Leica’s “Authentic” or “Vibrant” profiles give photos a distinct mood without heavy filters.
The twist: Xiaomi’s rear display means you can flip the phone and take selfies with the main camera system. For creators, that’s a cheat code.
Software & AI: Serious vs Playful (but both smart)
Everyone’s talking AI, and both brands are all-in—just with different vibes.
-
Samsung One UI (around 8.5) doubles down on productivity: live call translation, on-device summarization, smart clipboard, caption suggestions, and potentially the option to pick which AI engine helps you (Samsung’s, Google’s, etc.). There’s also talk of AI-assisted privacy tricks for the display. It feels like a phone that wants to be your smart coworker.
-
Xiaomi HyperOS 3 (Android 16) is more lifestyle-forward: XiaoAI learns patterns, surfaces the right widget at the right time (tickets, QR codes, music), and pipes handy info to the rear screen exactly when you need it. There are playful touches—animated pets that react to your phone’s status—and deeper cross-device links with Xiaomi laptops/TVs. Less boardroom, more everyday companion.
You can’t go wrong either way. Pick the personality that matches yours.
Special Extras: S Pen vs Second Screen
This is the headline trade-off.
-
Samsung S Pen is still the only mainstream stylus built into a slab phone. If you sketch, annotate PDFs, or prefer handwriting to typing, nothing else replaces it. It’s the one “once you have it, you miss it everywhere else” feature.
-
Xiaomi’s rear display is a fresh kind of utility. Notifications without flipping your phone, music controls, selfie framing with the good cameras, and that optional retro gaming shell for playtime. It’s the one “people will ask about it in a café” feature.
Which sounds more “you”? That’s your winner right there.
Ecosystem, Updates, and Real-Life Ownership
The unglamorous stuff matters too.
-
Samsung has the global network—carrier deals, trade-ins, accessories, strong repair channels, Knox security, and a well-known long update policy on Ultras. If you want the smoothest ownership experience in most countries, it’s the safe bet.
-
Xiaomi is expanding fast and promises long updates on flagships, but availability varies. In China and parts of Europe/Asia, support is solid. In North America, you’ll likely be importing. If you’re comfortable with that—and you love value—Xiaomi’s proposition is hard to ignore.
Quick Tiebreakers (Because Choices Are Hard)
-
Battery anxiety? Xiaomi.
-
Stylus person? Samsung.
-
Want the newest Snapdragon first? Xiaomi.
-
Care about carrier financing, trade-ins, and service? Samsung.
-
Creator who wants the best selfie quality? Xiaomi (rear-screen framing with main cams).
-
Prefer classic “premium” design and polish? Samsung.
-
Love fun gadgets and standout features? Xiaomi.
Here’s What This Really Means (Personal Take)
When you step back, it feels like we’ve got two different definitions of premium:
-
Samsung Galaxy S26 Ultra is the refined powerhouse. It tightens the screws on everything you already expect—screen quality, camera versatility, smarter software—and finally fixes a long-standing complaint (faster charging). It’s the phone you buy if you want zero surprises and maximum support. I won’t lie: the S Pen still makes it feel like a tiny tablet that happens to be a phone. If you’ve ever signed a PDF on the go or sketched a diagram in a meeting, you know how quietly life-changing that can be.
-
Xiaomi 17 Pro Max is the bold challenger. It chases fun and function at the same time: a huge battery you can actually notice, a secondary display that does more than look cool, and a camera system that’s creative without being fussy. The price undercuts, the specs overdeliver, and daily use (two-day battery, super-fast top-ups) feels… liberating. If you’re the “try new stuff first” friend, this is your energy.
Will Samsung’s AI push end up more useful than Xiaomi’s? Possibly. Will Xiaomi’s massive battery spoil you so much you’ll never go back? Also very possible. That’s the beauty of this face-off: there isn’t one right answer, just two excellent ones pointed at different kinds of users.
Final Verdict: Which Should You Buy?
-
Choose Samsung Galaxy S26 Ultra if you want the most complete premium experience: best-in-class display, stylus productivity, robust global support, and a serious AI toolkit that helps with work and security. You’ll pay more, but you’ll also stress less—about service, updates, and resale value.
-
Choose Xiaomi 17 Pro Max if you want maximum hardware for your money: two-day endurance, lightning-fast charging, the clever rear screen, and a camera setup that’s both Leica-tuned and creator-friendly. It’s the kind of phone that makes tech fun again—without asking your bank account for permission first.
What to watch next: when the S26 Ultra officially lands, keep an eye on (1) real-world battery tests, (2) how good that AI privacy mode actually is, and (3) whether the under-display selfie matches Xiaomi’s rear-screen-framed selfies. If Samsung closes the battery efficiency gap and nails its AI features, this battle gets even tighter.
How it affects you:
-
If you charge mid-day, hate battery anxiety, or shoot lots of rear-camera selfies, Xiaomi will feel like a quality-of-life upgrade.
-
If you sign docs, annotate slides, or live in a Samsung ecosystem (watch, buds, TV, Windows link), the Ultra integrates into your day like a pro tool.
Me? I remember the first time I used a Note-series pen, suddenly my phone did “laptop things.” But I also spent a week with a two-day phone once, and wow, not hunting for a charger changes your mood. That’s the decision in a nutshell: pen power vs battery freedom. Either way, the Samsung Galaxy S26 Ultra vs Xiaomi 17 Pro Max matchup is the most exciting head-to-head we’ve had in years—because both sides actually brought something new to the table.
