When I first thought about buying a used phone, I wasn’t sure what to expect. I had the same doubts about battery health, scratches, and hidden issues. But when I picked up a used Samsung Galaxy S23 Ultra, everything changed within the first few hours of using it.
It honestly didn’t feel like I was using a second-hand phone at all. The screen was huge, bright, and smooth. Apps opened instantly. The phone felt solid and premium in my hand, something you instantly notice when you’ve been using mid-range phones for a while.
This experience completely changed my view on flagship devices and how they age compared to supposedly good value mid-range phones. Let me walk you through exactly why this used flagship still feels like a premium phone, and it’s far better than mid-range devices even in 2026.
One of the biggest surprises for me was how snappy and responsive the S23 Ultra still feels even in early 2026. When the phone was brand new, it launched with the Snapdragon 8 Gen 2 chipset. It is a top-tier processor of its time & paired with up to 12 GB of RAM and UFS 4.0 storage. And even now, this combination remains extremely capable because:
The S23 Ultra 6.8-inch QHD+ Dynamic AMOLED display remains incredible, even by today’s standards:
Compared to many mid-rangers (which often stick to Full HD+ and 60 Hz), the difference in day-to-day experience is striking. I experienced smoother scrolling, richer color, and sharper text, making everything feel more premium.
Samsung Galaxy S23 Ultra comes with a quad-camera system centered around a 200 MP main sensor, backed by ultra-wide and dual telephoto lenses, including a 10× optical zoom. This surpasses many of the latest smartphones because it lets me take:
The camera also handles night scenes impressively well, thanks to strong image processing and optical stabilization. Even in 2026, the S23 Ultra produces images that look more refined than many newer mid-range camera systems.
Galaxy S23 Ultra runs all the latest apps comfortably. The phone originally launched with Android 13 and has continued to receive updates.
It is compatible with the latest social media apps like Instagram, TikTok, and Threads. Also, productivity suites like Google Workspace and MS Office work really well. Even the S23 Ultra runs advanced tools like AI utilities and cloud-based editors without breaking a sweat.
With its strong chipset and generous RAM, I rarely find an app that this phone can’t handle well, even as old software demands more resources with each passing year.
One of the biggest practical perks of owning a flagship like this is its multitasking power. With 12 GB RAM in my model (and UFS 4.0 storage), the phone handles heavy workloads with ease:
Even in 2026, this performance advantage holds because most mid-range phones prioritize cost savings over components like high-speed RAM and advanced chipsets.
Battery life is one major worry with used phones. But with the Galaxy S23 Ultra 5000 mAh battery, I’m still getting impressive 8 hours of screen on time on moderate usage. This means:
Comparing this to many mid-range smartphones with smaller batteries (4500 mAh or less) and slower charging, it’s a clear advantage.
You might think an older phone would feel outdated, but the S23 Ultra still has features many newer mid-range phones lack:
Adaptive 120 Hz AMOLED Display: Bright, fluid, and responsive, and noticeably better than standard 60 Hz mid-range displays.
S-Pen Support: lets you take quick notes, edit photos, scribble your ideas, and sign documents naturally, just like using a real pen.
Samsung DeX & Productivity Tools: It allows a desktop-style experience via USB-C or wireless. This is a distinctive feature & a productivity boost most mid-range phones don’t offer.
Ultra-Wideband (UWB) & NFC: Useful for modern connectivity tasks like precise file transfer or smart device interactions.
Here’s a quick personal breakdown of where the S23 Ultra beats typical mid-range phones:
| Category | S23 Ultra (Used) | Typical Mid-Ranger (2026) |
|---|---|---|
| Performance | Still very fast | Noticeable lag under heavy use |
| Battery | Full day easily | May struggle under heavy usage |
| Camera | Excellent in many conditions | Good but limited zoom/detail |
| Display | Premium AMOLED, 120 Hz | Often 60–90 Hz LCD/AMOLED |
| Multitasking | Excellent | Limited if the RAM is lower |
| Software Support | Longer life | Shorter update window |
| Productivity | Samsung DeX + features | Basic functionality |
Mid-range phones are of great value, no doubt about that. However, for everyday experience, the S23 Ultra still feels substantially more capable.
If someone asked me today whether a used Samsung Galaxy S23 Ultra is still worth buying compared to buying a new mid-range phone in 2026, my answer would be a very strong yes.
Buying a used Samsung Galaxy S23 Ultra made me realize that smart value doesn’t always mean buying new. A well-maintained flagship ages far better than most mid-range phones launched today. You get better performance, a better camera, a better display, and an overall smoother experience, and all that without stretching your budget.
