Design and Build Quality
When you hold either of these phones on your hand, they both feel premium, but the materials and weight give them very different personalities.
The Galaxy S25 Ultra has a titanium frame, which makes it feel tough and solid when holding, almost like holding a tank. It weighs 218g, which gives it that “built like a beast” vibe. On the front and back of the phone, Samsung uses Gorilla Glass Armor 2, which not only protects the screen from drops and scratches but also reduces glare, so the display stays clear in bright light.
One the other hand, the OnePlus 13 uses Ceramic Guard for the screen and a slightly lighter frame, weighing in at about 210–213g. It’s got a premium finish too and is rated IP68 and IP69 meaning it’s super resistant to dust and water, even in tougher conditions.
Overall:
Samsung feels sturdier and more industrial.
OnePlus is lighter and easier to handle, with excellent durability too.
If you like your phone to feel like a metal slab of power, go for the Ultra. But if you prefer something a little more pocket-friendly and less bulky, then OnePlus wins on comfort.
Display Comparison
The phone screen is the first thing you notice when you power up you phone, and this is where Samsung phones usually leads the pack.
On the Galaxy S25 Ultra is featured a 6.9-inch AMOLED display with LTPO tech and a 120Hz refresh rate. Translation? It’s massive, insanely smooth when scrolling or gaming, and ultra-colorful. It also hits a peak brightness of 1,860 nits, which means the S25 ultra screen stays visible even under bright sunlight. Plus, Samsung added an anti-glare coating, so outdoor use is no problem at all.
The OnePlus 13 phone isn’t far behind the samsung. It sports a 6.82-inch AMOLED display, also with a 120Hz refresh rate, so it’s equally fluid and vibrant. But its peak brightness tops out at 1,104 nits, which is decent for indoors, but not quite as effective in direct sunlight.
The result?
If you’re always outdoors, or you binge Netflix on your phone in the sun, the Galaxy S25 Ultra gives you a clearer, brighter experience than the OnePlus 13.
Although the OnePlus 13 is still gorgeous to look at, but it doesn’t hit the same visibility levels under bright conditions with that of the S25 Ultra.
Camera System Breakdown
Both phones come with beast-level cameras, but each one has its own strengths depending on what kind of photos you like to take.
The Samsung Galaxy S25 Ultra really shines in selfies, portraits, panoramas, and night photos. Samsung has tuned its cameras to deliver clean, sharp images with great skin tones, rich detail, and solid contrast, even in low-light. Selfies, it photos come out looking more natural and well-lit.
The OnePlus 13, on the other hand, crushes it in macro shots (those super close-up details) and mid-range zoom, like between 5× to 30×. Where Samsung sometimes over-processes zoom photos, OnePlus keeps them natural and clear. That’s great for capturing faraway subjects like wildlife or concert stages.
So here’s the camera breakdown:
If it on image go for Samsung if you care about selfies, portraits, and low-light photography.
Go for the OnePlus if you shoot a lot of zoomed or macro shots and want more natural tones.
If you want a general-purpose camera that nails most conditions, Samsung edges out. But if your photo style is more zoom-heavy or detail-focused, OnePlus brings serious value.
Performance and Software Experience
When it comes to speed and day-to-day use, both the Galaxy S25 Ultra and OnePlus 13 are lightning fast, but they feel different depending on how you use your phone.
The Samsung Galaxy S25 Ultra runs on the Snapdragon 8 Gen 3 for Galaxy, which is just a slightly boosted version of the chip in most 2025 flagship Androids. It’s been fine-tuned by Samsung to push a little more performance, especially for gaming and graphics-heavy tasks. Apps open instantly, switching between tabs is seamless, and video editing feels smooth, even 4K.
The OnePlus 13, though, also uses the Snapdragon 8 Gen 3, and surprisingly, it actually beat Samsung in benchmark tests. In a Geek Bench multi-core test, it scored 7,450, while the S25 Ultra got 7,338. Not a massive difference, but it shows OnePlus knows how to optimize their phones for raw performance.
What about the software experience?
Samsung’s One UI 6.1 is feature-packed and It’s great if you love extras like Samsung DeX (which lets you turn your phone into a desktop with a monitor), S Pen support, and deep customization.
OnePlus OxygenOS is much cleaner and lighter which make It feels closer to stock Android, meaning fewer pre-installed apps, faster animations, and a simple, no-frills experience.
So if you love bells and whistles on a phone, like handwriting notes, customizing every screen, or turning your phone into a mini-PC—Samsung wins. But if you’re all about smooth, fast, and clean performance without distractions, OnePlus is your phone.
Battery Life and Charging
Battery life is where the OnePlus 13 straight-up flexes.
This phone clocked 17 hours and 46 minutes in real battery tests, that’s nearly two full days of use with regular tasks like social media, emails, and video.
Plus, it charges insanely fast: from 0% to 61% in just 15 minutes, and can boast of a full charge in under 30 minutes. And the best part? It includes the charger in the box, which most brands (including Samsung) no longer do.
Now the Galaxy S25 Ultra isn’t bad it can lasted 15 hours and 40 minutes, which is still great for a flagship phone. But it does lag a bit behind in charging speed. After 15 minutes, it’s only at 36%, and a full charge takes over an hour. Also, no charger included in the box, so you’ll need to buy one charger separately if you don’t already have one.
So the clear verdict?
If battery life and fast top-ups matter most to you, OnePlus dominates here.
If you’re okay charging overnight or don’t mind slower speeds, Samsung is still a solid choice.
AI and Smart Features
2025 is peak AI era in phones and Samsung is leading the charge with a full suite of smart tools baked into the S25 Ultra.
Here’s what Samsung’s Galaxy AI brings to the table:
- Circle to Search: Draw a circle around anything on your screen and instantly get Google results.
- Live Translate: Talk to someone in another language during a call, and it translates live in real time.
- Generative Edit: Move or erase objects in your photo with AI that fills in the background naturally.
- Note Assist: Turn messy notes into clean summaries or bullet points, with translation and rewrite tools.
The OnePlus 13 is much simpler in this area. It includes Google’s Magic Editor for photo edits using AI, but that’s about it. No deep system-level tools like Samsung’s.
In short:
If you want your phone to feel smart, like truly helpful on a daily level—Samsung is the one.
If you don’t care about AI tricks and just want a fast phone, OnePlus keeps it minimal.

- You want flagship performance for way less money
