Lenovo Legion Go S Review

Overview

The Lenovo Legion Go S is the answer to a question handheld gamers spent 2024 asking: what happens when SteamOS — the operating system that made the Steam Deck so beloved — ships on someone else's, more powerful hardware? Launched in February 2025 as a Windows 11 handheld with an entry-level AMD Ryzen Z2 Go chip, the Legion Go S was an underwhelming debut that reviewers told people to skip. Lenovo then did something rare: it fixed the product in place. A mid-2025 revision swapped the OS to native SteamOS — the first non-Valve handheld to ship it out of the box — and added a Z1 Extreme configuration, turning a launch-day lemon into one of the most praised handhelds of the year. IGN called the Z1 Extreme SteamOS version "Steam Deck 1.5" and gave it a 9/10 Editors' Choice; PCMag handed the Z2 Go SteamOS model 4/5 stars and its own Editors' Choice award.

That's the good news, and there is a lot of it. The uncomfortable news is pricing. Lenovo promised at CES 2025 that the SteamOS Legion Go S would start at $499.99. The Z2 Go model actually launched at $599 (SteamOS) to $729 (Windows), the Z1 Extreme at $829. Then, in April 2026, Best Buy — the device's primary retail partner — raised prices almost overnight: the Z2 Go jumped from $649.99 to $989.99 and the Z1 Extreme from $899.99 to $1,579.99, hikes of 52% and 76% that Lenovo blamed on the memory shortage. Reddit's r/LegionGo community dubbed it "the GoPocalypse," and the value conversation around this handheld flipped from "best budget SteamOS machine" to "why would I pay this when a Steam Deck OLED or ROG Ally X costs less?"

This review synthesizes official Lenovo specs, benchmark data from IGN, Tom's Guide, PCMag, and Notebookcheck, and owner sentiment from Reddit and Amazon to answer the real question: in mid-2026, is the Legion Go S still worth buying — and at what price?

Build Quality and Design

The Legion Go S abandons the original Legion Go's ambitious Switch-style detachable controllers for a unibody design closer to the ROG Ally X, and that decision pays off in comfort. The chassis measures 299 x 128 x 42 mm (11.77 x 5.02 x 0.88 inches) and weighs 736 grams (1.61-1.63 lbs) — lighter than the 854g original Legion Go but heavier than the Steam Deck OLED (~640g) and ROG Ally X (~678g). Press reviews and owner feedback agree the rounded grips and anti-slip texture make it comfortable for long sessions despite the weight; Tom's Guide called the ergonomics among the best in the class, and Reddit sentiment on ergonomics runs heavily positive.

Controls are a clear step up from the original Legion Go. The face buttons, asymmetrical Hall Effect joysticks with RGB rings, and a rounded "Pivot D-pad" all drew praise for responsiveness. The triggers have two-position locks to shorten travel for FPS play, and the rear paddles are clickier than the original Legion Go's. There is one design head-scratcher: a comically small touchpad tucked below the right stick. IGN called it a "major bugbear" on the Windows version, where navigating the OS demands pointer input. On the SteamOS version it matters far less — the OS is built for controller navigation — but owners who dual-boot or use desktop mode still find it fiddly, and it's the single most common controls complaint in community feedback.

Ports and layout are solid: two USB4 (40 Gbps) USB-C ports with DisplayPort support for docks and eGPUs, a microSD slot, and a 3.5mm headphone jack. Notebookcheck's teardown notes the storage is a replaceable M.2 2242 SSD, a welcome upgrade path. The microSD slot sits on the bottom edge, which is awkward in a dock but not a real problem. Two forward-facing 2W speakers sound decent for a handheld, and there's no kickstand — a cost cut Tom's Hardware specifically flagged, since propping the device up for desktop use requires a case or stand. The SteamOS version comes in a "Nebula Nocturne" dark purple that reviewers uniformly liked; the Windows version is Glacier White.

Key Features

• Native SteamOS (first non-Valve handheld): Ships with Valve's Linux-based OS out of the box — the same software experience as the Steam Deck: suspend/resume, per-game TDP and refresh controls, plug-and-play with the Steam library. Press consensus is that this alone transforms the device. Setup takes minutes rather than the multi-storefront slog of Windows handhelds.
• 8-inch 1920x1200 IPS display at 120Hz with VRR: 500 nits rated (Tom's Guide measured 441 nits), 16:10, 10-point touch. Tom's Guide measured 116.3% sRGB and 82.4% DCI-P3 coverage with a Delta-E of 0.33. Not OLED, no HDR — PCMag notes the Steam Deck OLED's panel outclasses it in contrast and HDR — but reviewers consistently call it one of the best LCDs in handhelds, and the extra resolution over the Deck's 800p is a real advantage.
• Two chip options: the baseline AMD Ryzen Z2 Go (Zen 3+, 4 cores/8 threads, RDNA 2 graphics, up to 40W) and the flagship Z1 Extreme (Zen 4, 8 cores/16 threads, RDNA 3) — the same APU family as the ROG Ally X and original Legion Go.
• 32GB LPDDR5X-6400 RAM on the Z1 Extreme: with 10GB allocatable to the GPU, versus the Steam Deck's 6GB — the difference that makes VRAM-hungry 2025-2026 titles like Monster Hunter Wilds playable.
• Hall Effect joysticks and triggers: no potentiometer wear, no drift — a durability win owners consistently cite.
• 55.5Wh battery with Super Rapid Charge: 30% in 10 minutes, ~70% in 30, full charge in about 80 minutes on the included 65W adapter.
• Dual USB4 with DisplayPort: dock it, run an eGPU, or drive an external monitor at 40 Gbps.

Performance

The Legion Go S is really two different products depending on the chip, and the OS matters as much as the silicon.

The Z1 Extreme + SteamOS version is the star. In IGN's testing, the Z1 Extreme Legion Go S scored 3,433 in 3DMark Time Spy — nearly double the Steam Deck's 1,715 — and 7,865 in Fire Strike versus the Deck's 4,322. Real games back up the synthetic numbers: Cyberpunk 2077 at 800p High with FSR Performance ran at 61 fps versus the Steam Deck's 28 fps, and Monster Hunter Wilds hit 31 fps average where the Deck struggled to 19 with single-digit dips. Tom's Guide's Z1 Extreme unit ran Doom: The Dark Ages at 56-61 fps at 800p with FSR, and roughly 25 fps at native 1200p medium without upscaling. This is comfortably the most powerful SteamOS handheld you can buy in 2026, and it's why IGN crowned it "Steam Deck 1.5."

SteamOS itself is worth frames. Tom's Guide benchmarked the same-class hardware under both OSes and found the SteamOS build trounced its Windows twin: Assassin's Creed Mirage at 32 fps versus 21 fps, Dirt 5 at 32 versus 20, Shadow of the Tomb Raider at 39 versus 16 — all at 1200p maximum settings. Notebookcheck measured a 24% CPU advantage under SteamOS and noted quieter fan behavior. PCMag's testing echoed the pattern. The lesson is consistent across every outlet: Windows overhead costs roughly a third of the performance on this hardware, and SteamOS is where the Legion Go S actually lives up to its potential.

The Z2 Go is honest about being entry-level. IGN's Windows Z2 Go review measured 2,179 in Time Spy — about 35% behind the ROG Ally X — and found it "struggles to keep up" at $729, scoring the device 6/10 with the famous advice to wait for SteamOS. On SteamOS the Z2 Go is more respectable: Notebookcheck measured Cyberpunk 2077 at 37.8 fps at 1080p Low in performance mode (21.6 balanced, 10.5 in the 7W low-power profile), and PCMag called the SteamOS Z2 Go "a better SteamOS handheld than the actual Steam Deck" — at 1200p the extra resolution means it runs harder than the Deck's 800p, but the chip trades blows with (and often beats) the Deck's older silicon.

Battery life is the weak spot. The 55.5Wh pack is decent on paper, but these chips drink power: PCMag's Z2 Go SteamOS unit lasted 1 hour 39 minutes in Baldur's Gate 3 at 50% brightness, versus 2 hours 15 minutes for the Steam Deck OLED in the same test. Tom's Guide got roughly 1.5 hours of Doom: The Dark Ages at 1200p in performance mode before a low-battery warning, and IGN's PCMark 10 run on the Windows version returned 4 hours 29 minutes of mixed use. Plan for 1.5-2 hours of demanding play — fine for a commute, short for a flight — and lean on the fast charging. Super Rapid Charge is genuinely good: 30% in ten minutes is the difference between "dead" and "one more session."

Thermals and noise. The ColdFront cooling keeps the device cool to the touch — Tom's Guide measured the underside at 83°F in its heat test — but the fans get loud. "Loud fans" is a listed con in both Tom's Guide and PCMag reviews, and Notebookcheck measured up to 39.9 dB(A) at max fan speed in performance mode. It's not annoying enough to be disqualifying on a handheld, but it's audible in a quiet room, and owners note the fan spins up even during downloads and updates.

Pros and Cons

Pros:

• First non-Valve handheld with native SteamOS — the full Steam Deck software experience out of the box
• Z1 Extreme config is the most powerful SteamOS handheld available: roughly 2x the Steam Deck's GPU performance in IGN's benchmarks
• Excellent 8-inch 1200p 120Hz IPS display with VRR — one of the best LCDs in the category
• Comfortable unibody ergonomics with Hall Effect sticks, adjustable trigger locks, and rear paddles
• 32GB RAM on the Z1 Extreme handles modern VRAM-hungry titles the Steam Deck can't
• Fast charging (30% in 10 minutes) and dual USB4 ports with eGPU/DisplayPort support

Cons:

• The April 2026 price hikes (up to 76%) destroyed the value case: $989.99 for the Z2 Go and $1,579.99 for the Z1 Extreme at Best Buy as of mid-2026
• Battery life is mediocre: roughly 1.5-2 hours of demanding play, worse than the Steam Deck OLED
• Loud fans under load (up to ~40 dB(A) in Notebookcheck's measurements)
• The tiny touchpad is nearly useless for Windows navigation and desktop mode
• Z2 Go model is a 4-core/8-thread entry chip — fine for 800p-1080p medium, but it trails the Z1 Extreme and ROG Ally X class by 30%+
• No HDR, no OLED, no kickstand

Who Should Buy This

The Legion Go S with SteamOS is for the player who wants the Steam Deck's console-like simplicity but finds the Deck's hardware — its 800p screen, aging APU, and 6GB GPU allocation — limiting. If you live in Steam's ecosystem, want to play 2025-2026 AAA titles on the go, and value suspend/resume and zero-config gaming, the Z1 Extreme version is the best SteamOS handheld money can buy. The Z2 Go version makes sense as a Steam Deck replacement for someone who wants the bigger, sharper screen and doesn't need max settings.

Skip it if you need more than ~2 hours of battery away from a charger, if you rely on Game Pass, Epic, or other non-Steam storefronts (possible on SteamOS, but it requires desktop-mode tinkering that most buyers won't enjoy), or if you want OLED HDR. And skip the Z1 Extreme at its current $1,579.99 street price — at that number, value is gone entirely.

Alternatives to Consider

• Valve Steam Deck OLED ($549-$649 MSRP, higher on the street in 2026): The incumbent. OLED HDR panel, better battery life (2h15m in PCMag's same-test comparison), lighter at ~640g, and the same SteamOS software. Less GPU horsepower and only 800p, but at a far saner price — it's the value pick against the hiked Legion Go S.
• ASUS ROG Xbox Ally X / ROG Ally X (Z2 Extreme, ~$1,000-1,200 street): The Windows handheld to beat. More powerful than the Z1 Extreme Legion Go S, 80Wh battery (roughly double the Go S's), 24GB RAM, and $1,579.99 buys you one with money left over — VideoCardz and community sentiment both point here as the smarter spend at current prices. Windows 11 fiddliness is the trade-off.
• Lenovo Legion Go 2 (Z2 Extreme, 8.8-inch OLED 144Hz): The premium sibling. Faster chip, gorgeous OLED, detachable controllers, kickstand, and fingerprint reader — but also pricey and aimed at enthusiasts willing to pay for the best.

At the Legion Go S's original pricing, the Z1 Extreme SteamOS model beat all three on value. At 2026 street pricing, the Steam Deck OLED and ROG Ally X become the rational alternatives.

Verdict

The Lenovo Legion Go S is, hardware and software aside, one of the best handhelds ever made: native SteamOS on a big 120Hz 1200p screen with Z1 Extreme-class performance is a combination no other product offers in 2026. Every major outlet that reviewed the SteamOS version came away impressed — IGN 9/10, Tom's Guide 4/5, PCMag 4/5 Editors' Choice, Notebookcheck 82% — and owner sentiment on the device itself is strongly positive. The hardware is a legitimate 9/10 product.

But a review in mid-2026 has to talk about the price. Lenovo's April 2026 hikes of 52-76% at Best Buy moved the Z2 Go to $989.99 and the Z1 Extreme to $1,579.99 — prices that put the device in a different competitive class where it no longer wins. The community reaction was immediate and angry, and it's justified: the same Z1 Extreme model was $649 during Black Friday 2025. If you can find one at launch-era pricing — $599-649 for the Z2 Go, $829 for the Z1 Extreme, or anything resembling a sale — it remains one of the best handheld purchases available. At current street prices, wait for a sale or buy the Steam Deck OLED. 7.5/10.
