Lenovo Legion Go S Steam Edition Review: SteamOS Handheld Tested
content: The Handheld Gaming Crossroads
Imagine standing before two paths: one leads to the familiar comfort of your Steam Deck OLED, the other to Lenovo's ambitious Legion Go S Steam Edition promising more power and a vibrant 8-inch display. After two weeks of testing this dark purple contender, I can confirm it delivers genuine innovation—but with significant trade-offs. SteamOS transforms this Windows-based hardware into something special, yet battery limitations and looming market shifts create real dilemmas for buyers.
Hardware Showdown: Legion Go S vs Steam Deck
Design and Ergonomics
The Legion Go S Steam Edition immediately stands out with its unique dark purple chassis and 8-inch 120Hz display. Side-by-side with the Steam Deck OLED, the size difference is stark: Lenovo's device is noticeably thicker and 100g heavier. While the ergonomic shape prevents discomfort during short sessions, extended play reveals the weight penalty. The offset thumbsticks and redesigned D-pad offer good control, though the small touchpad feels more like an afterthought than the Steam Deck's functional trackpads.
Performance Benchmarks Revealed
Testing both the Z2 Go ($600 model) and Z1 Extreme ($830) variants exposed surprising truths. Using identical Steam Deck settings (800p, medium):
| Device | Cyberpunk 2077 | Forza Horizon 5 | Thermal Performance |
|---|---|---|---|
| Legion Go S (Z2 Go) | 61 FPS | 68 FPS | 72°C peak |
| Legion Go S (Win OS) | 50 FPS | 75 FPS | 70°C peak |
| Steam Deck OLED | 48 FPS | 62 FPS | 68°C peak |
Critical finding: SteamOS boosts performance by 22% in Cyberpunk versus Windows on identical hardware. However, the Z1 Extreme's $230 premium seems unjustified for most gamers—it's only 15-20% faster than the Z2 Go in real-world testing.
The SteamOS Experience: Refined But Evolving
Console-Like Simplicity
After the latest beta update, SteamOS transforms the Legion Go S into a pick-up-and-play machine. Performance profiles (Low Power/Balanced/Performance) now work reliably, letting you prioritize battery or frames. The true advantage emerges in daily use: one-button sleep/wake functionality works flawlessly, and you'll never fumble with driver updates. This is PC gaming convenience distilled to console simplicity.
Current Limitations and Quirks
Despite improvements, my review unit revealed ongoing challenges:
- Game compatibility issues persist, with titles like The Last of Us Part II locking resolution to 1280x800 (mistaking the device for a Steam Deck)
- Touchpad and RGB controls remain non-functional in SteamOS
- Occasional TDP setting resets during sleep mode
My assessment: These aren't dealbreakers but highlight SteamOS's growing pains on third-party hardware. Valve's small team must prioritize broader compatibility updates.
Battery Life and Real-World Usability
Power Efficiency Realities
Testing Baldur's Gate 3 on Balanced mode (40% brightness) yielded just over 2 hours runtime—slightly worse than the Steam Deck OLED despite its larger 55Wh battery. The Z2 Go chip draws more power than Steam Deck's custom APU, negating the capacity advantage. Pushing performance mode slashes runtime to 90 minutes, useful only when plugged in.
Thermal and Acoustic Performance
Lenovo's cooling solution deserves praise. Even at 35W TDP, the device never exceeded 75°C in my stress tests. However, fan noise becomes intrusive above 20W—I recommend headphones for performance gaming. The ergonomic grip ensures heat stays away from palms, a thoughtful design touch.
Market Analysis: Why This Launch Matters
The Valve-Microsoft Power Struggle
Valve's 350-employee team has achieved the impossible: forcing Microsoft to reportedly develop a dedicated handheld Windows version. SteamOS's advantages—seamless sleep/wake, Proton performance gains, and console-like UX—exposed Windows' inadequacies. But Microsoft's imminent response could disrupt SteamOS's momentum.
Pricing and Value Verdict
At $600, the Legion Go S Steam Edition (Z2 Go/16GB/512GB) faces stiff competition:
- Against Steam Deck OLED ($550): Worth the $50 premium for the larger screen and extra performance if you value those
- Against Windows handhelds: Harder to justify when original Legion Go (Z1 Extreme) sells for $600
- Future-proofing concern: Microsoft's handheld-optimized Windows could erode SteamOS's advantages
My recommendation: Buy only if you specifically want a larger-screen SteamOS device now. Others should wait for software maturation or market shifts.
Actionable Insights for Gamers
Immediate Performance Checklist
- Enable FSR 2.0 in supported games to gain 15-20% fps at minimal quality loss
- Set TDP to 15W in Balanced mode for optimal battery/performance equilibrium
- Disable RGB lighting (when supported) to extend playtime by 8-12 minutes
Recommended Upgrade Path
- SSD replacement: Prioritize this over buying the 1TB model—installation takes 10 minutes
- ProtonDB.com: Check game compatibility before purchasing titles
- JSAUX Dock: Best value docking solution with 4K output
Final Verdict: A Promising But Imperfect Contender
The Legion Go S Steam Edition proves third-party SteamOS devices can work, delivering tangible benefits like 22% better Cyberpunk performance versus Windows. However, battery limitations and the $600 price create a narrow audience. Valve's partnership with Lenovo deserves applause for pushing handheld innovation, yet Microsoft's looming response could redefine this space within months.
"For now, I'm returning to my Steam Deck OLED—but only because the next generation of handhelds will make today's choices look primitive."
