The Samsung Galaxy Note20 Ultra 5G (Snapdragon) is Samsung’s North American flagship “phablet” iteration that ships with the Qualcomm Snapdragon 865+ and an S‑Pen. Physically it is a large 6.9‑inch device (164.8 x 77.2 x 8.1 mm) with a 1440×3088 OLED panel at 496 ppi and an adaptive refresh rate up to 120 Hz. Storage options include 128, 256 and 512 GB and the unit reviewed by public benchmarks reports 12 GB of RAM and Android 10 as the shipping OS.
This review synthesizes published benchmark aggregates and lab testing referenced in the research brief: UL 3DMark Wild Life scores and stability data, DxOMark’s display protocol and notes comparing the Snapdragon model to the Exynos model, coverage from Wired and Counterpoint, Geekbench dataset listings, plus user discussion threads that reflect real‑world impressions. I rely only on the figures and findings documented in those sources.
High level: the Note20 Ultra (Snapdragon) still delivers one of the best large OLED experiences of its generation and the S‑Pen responsiveness earned praise, but the Snapdragon 865+ variant shows measurable limits in sustained GPU stability and is now an older silicon choice. If you want a large, sharp 120 Hz OLED with an accurate stylus and a 108 MP camera, it remains compelling; if your priority is top‑tier, long‑term GPU headroom and modern chipset longevity, there are better options today.
How fast is the Snapdragon 865+ in day‑to‑day and benchmarked workloads?
Synthetic GPU testing reported by UL shows a 3DMark Wild Life score of 4186 and a Wild Life Unlimited result of 4167; the device’s Wild Life graphics test 1 ran at about 25 FPS with a stability figure of 82%. That stability percentage indicates performance variance under sustained load — useful evidence that thermal or power‑management limits can reduce peak throughput over longer sessions.
Qualitative coverage in Wired and Counterpoint in the research brief flags the chipset as a weak point relative to newer silicon: Wired summarized the device as a good phone hampered by an older processor, while Counterpoint noted Qualcomm’s lead on benchmarks and battery life for contemporaries. Expect solid everyday responsiveness but reduced sustained 3D/GPU headroom compared with more recent flagship SoCs.
Is the 6.9" OLED still one of the best mobile displays?
DxOMark’s display testing in the brief confirms the Note20 Ultra’s 6.9‑inch OLED (1440×3088, 496 ppi) and reports that Samsung’s Exynos variant previously earned a top display score; DxOMark tested the Snapdragon version specifically to quantify tuning differences introduced by the chipset. The panel supports refresh rates up to 120 Hz and retains the high resolution and pixel density expected of a 2020 flagship.
Because DxOMark called out chipset‑sensitive tuning, expect slight behavioral differences between the Snapdragon and Exynos models (for example in color/brightness or adaptive refresh behavior) even though the OLED hardware and resolution are identical. The screen remains a key strength on paper: large diagonal, high pixel density, and 120 Hz support.
Does the 108 MP camera meet expectations?
The research brief lists a 108 MP main camera as part of the device specification and cites Wired’s positive summary: 'Great set of cameras.' Those sources indicate that camera hardware and imaging pipeline were competitive at launch and remain a strong point for photography and video within the device’s original generation.
DxOMark’s decision to re‑test the Snapdragon variant underscores that chipset/software tuning affects display and imaging results; while hardware specs remain constant, you should expect small differences in camera processing between regional chipset variants.
Is the Note20 Ultra a well‑built large phone?
The measured dimensions from DxOMark are 164.8 x 77.2 x 8.1 mm, confirming a large 'phablet' footprint. The device pairs a very large OLED with a centered circular front camera cutout and the traditional Note S‑Pen integration, which was singled out positively in coverage for its extremely low latency (Wired described the new S‑Pen as having 'next‑to‑zero latency').
Given the size and screen area, expect the usual tradeoffs for a 6.9‑inch device: excellent media immersion and stylus usability at the cost of pocketability and one‑hand use. Build quality was not contested in the brief; the device is presented as Samsung’s flagship class hardware from 2020.
Battery, software and real‑world ownership questions
The research brief includes Counterpoint’s note that Qualcomm might be slightly ahead on battery life for contemporaries; UL cautions that benchmarked battery life in public datasets is highly variable and sensitive to screen brightness. No single, controlled battery runtime figure is provided in the brief for the Snapdragon Note20 Ultra, so expect battery behavior to be typical of large‑screen flagships of its generation and sensitive to refresh‑rate and brightness settings.
Software shipped as Android 10 per the benchmark metadata in the brief. Given the device’s age in 2026 and the chipset vintage, buyers should verify current OS update status and carrier support if long‑term software updates and security patches are important to them.
Pros & Cons
- ✅ 6.9‑inch OLED display, 1440×3088 resolution at 496 ppi with adaptive refresh up to 120 Hz (DxOMark specs)
- ✅ S‑Pen with extremely low latency (Wired described it as 'next‑to‑zero' latency)
- ✅ 108 MP main camera hardware and flagship‑class imaging at launch (listed in device specs and coverage)
- ✅ Multiple storage options (128 / 256 / 512 GB) and 12 GB RAM reported in benchmark metadata
- ✅ Snapdragon 865+ provides strong single‑session responsiveness for typical app use
- ❌ Snapdragon 865+ shows reduced sustained GPU stability — 3DMark Wild Life stability recorded at 82% and graphics test ~25 FPS (UL results)
- ❌ Chipset is older generation; Wired summarized the phone as 'good phone, bad processor' indicating limits versus newer silicon
- ❌ Device ships with Android 10 in published metadata; software‑update longevity may be limited
- ❌ Public benchmark popularity is effectively 0.0% in the UL dataset, reflecting low recent testing activity for this variant
How It Compares to the Competition
- Samsung Galaxy Note20 Ultra (Exynos 990) — Same Note20 Ultra hardware but with Samsung Exynos 990; DxOMark notes differences in display and tuning between the Exynos and Snapdragon variants.
- Samsung Galaxy S20 Ultra — Another large‑screen 2020 Samsung flagship — similar class in size and camera ambitions, with different chipset/regional variants to consider.
- OnePlus 8 Pro — Contemporary large‑screen Android flagship that emphasized high refresh rates and competitive performance tuning in 2020.
- iPhone 12 Pro Max — Apple’s large‑screen 2020 flagship alternative; different OS and ecosystem, with distinct performance and update policies.
Who Should Buy This & Who Should Skip It
Buy it if: Buy this if you want one of the largest 120 Hz OLED screens of its generation, need an S‑Pen with very low latency, and value high‑resolution (108 MP) camera hardware with ample RAM and storage options. It’s a practical choice for someone prioritizing display real estate, stylus workflows and flagship‑class imaging hardware from 2020.
Skip it if: Skip this if you need the absolute latest sustained GPU performance, the longest future OS support or the newest chipset headroom — benchmark data shows the Snapdragon 865+ variant has reduced stability under sustained 3D load. Buyers who prioritize multi‑year software updates or top‑tier gaming consistency should consider newer‑silicon alternatives.
