OnePlus 12 vs Samsung Galaxy S24 Ultra: Full Comparison
I've spent considerable time with both the OnePlus 12 and Samsung Galaxy S24 Ultra, and they represent completely different philosophies in the Android flagship space. OnePlus keeps pushing its "flagship killer" approach with aggressive pricing, while Samsung has doubled down on being the everything-phone for people who want it all.
Let's talk about what makes the OnePlus 12 compelling at $799. That 100W SuperVOOC charging is genuinely ridiculous—I'm talking full charge on the 5400mAh battery in under 30 minutes. Samsung's 45W feels slow by comparison. The display hits 4500 nits peak brightness, which makes the screen noticeably easier to read outdoors than the S24 Ultra. OxygenOS has gotten leaner too, with less bloatware cluttering up your app drawer compared to One UI. You're getting the same Snapdragon 8 Gen 3 processor for $500 less than Samsung's asking price.
But here's where the comparison gets interesting.
Samsung is playing the long game with seven years of software updates. Your S24 Ultra will still get security patches in 2031, which is unprecedented for Android. That built-in S Pen turns the phone into something different entirely—I use it constantly for quick notes and photo editing. The camera system is where Samsung really pulls ahead with dual telephoto lenses offering 3x and 10x optical zoom, plus that 200MP main sensor that captures incredible detail.
The ecosystem piece matters more than people think. If you've already got Galaxy Buds, a Galaxy Watch, or a Samsung tablet, the S24 Ultra becomes the center of everything. Quick Share, DeX desktop mode, Universal Clipboard—these features actually work together. OnePlus doesn't have an equivalent ecosystem, though it plays nicely with standard Android accessories.
So who should buy what? The OnePlus 12 makes perfect sense if you upgrade every 2-3 years and want maximum performance per dollar. That charging speed alone is a daily quality-of-life improvement. The Samsung Galaxy S24 Ultra justifies its premium if you keep phones for 4+ years, need the S Pen for work, or you're already invested in Samsung's hardware universe. The camera versatility is unmatched if photography matters to you.
Both are genuinely excellent phones. I'd personally choose based on how long you plan to keep the device and whether that S Pen functionality appeals to you.

Frequently Asked Questions
Both will easily last you all day. The OnePlus 12 has a slightly bigger 5400mAh battery versus Samsung's 5000mAh, but the real difference is charging speed. OnePlus goes from 0-100% in 26 minutes with 100W charging, while Samsung takes about 65 minutes at 45W. If you forget to charge overnight, OnePlus is way more forgiving.
Samsung wins by a landslide here—7 years of OS and security updates for the S24 Ultra versus OnePlus's 4 years of OS updates and 5 years of security patches. If you're the type to keep a phone for 5+ years, Samsung is the obvious pick.
Depends what you need. The extra money gets you the S Pen, way better zoom with 10x optical versus 3x, those 7 years of updates, and full Samsung ecosystem integration. If you'll actually use those features, absolutely worth it. If you just want a fast phone that charges quickly, save your money and get the OnePlus.
Samsung takes this pretty easily. The 200MP main sensor captures more detail, and those dual telephoto lenses (3x and 10x optical) are in a different league from OnePlus's single 3x zoom. OnePlus takes good photos in normal situations, but Samsung's computational photography and zoom range are much better for serious photography.
Sure, they'll connect via Bluetooth just fine. But you lose all the Samsung-specific features like automatic pairing, optimized spatial audio, and the Galaxy Wearable app integration. They'll work, but not nearly as well as they do with an actual Samsung phone.
Buy the OnePlus 12 if you upgrade every 2-3 years and want the best value—it's $500 cheaper with superior charging speeds. Choose the Galaxy S24 Ultra if you keep phones for 5+ years and need advanced features like the S Pen and exceptional zoom capabilities, since Samsung's 7-year update commitment justifies the premium price.
The OnePlus 12 ($799) focuses on speed and value with industry-leading charging, while the S24 Ultra ($1,299) prioritizes longevity with 7 years of updates, S Pen support, and superior camera zoom. Pick OnePlus for immediate savings or Samsung if you want a long-term investment with more built-in productivity features.
