Lenovo Legion Go S Review: The Best Steam Deck Upgrade

Note: This review-style article focuses on the Lenovo Legion Go S as a Steam Deck upgrade, especially the SteamOS edition. The Windows version is discussed because it matters, but the real story is what happens when Lenovo’s excellent handheld hardware meets Valve’s console-like software.

Introduction: The Steam Deck Finally Has a Serious Cousin

The Steam Deck changed handheld PC gaming by proving that people did, in fact, want to play their Steam libraries on the couch, in bed, at the airport, and in that mysterious five-minute gap before dinner. But after a few years, even the beloved Deck has started to show its age. Its interface is still wonderful, its game library is huge, and the OLED model remains a joy. Yet gamers who want a sharper screen, higher refresh rate, stronger performance, and more modern handheld hardware have been looking for the next step.

Enter the Lenovo Legion Go S, a handheld gaming PC that feels like Lenovo listened to the Steam Deck crowd and said, “What if we made that idea bigger, smoother, and a little more ambitious?” The Legion Go S is not simply a smaller version of the original Lenovo Legion Go. It drops the detachable controllers and wild “FPS mode” in favor of a cleaner, more comfortable, all-in-one design. More importantly, it became one of the first major third-party handhelds to embrace SteamOS, which is the secret sauce that makes this device feel like a real Steam Deck upgrade rather than just another Windows tablet with joysticks attached.

Is it perfect? No. Battery life can still be moody, the small touchpad is not a Steam Deck replacement, and choosing the wrong configuration can turn this exciting handheld into an overpriced “almost.” But when you look at the SteamOS version, especially the stronger Ryzen Z1 Extreme configuration, the Lenovo Legion Go S becomes one of the most compelling handheld gaming PCs available.

Lenovo Legion Go S Specs: What You Need to Know

The Lenovo Legion Go S is built around an 8-inch WUXGA IPS display with a 1920 x 1200 resolution, a 16:10 aspect ratio, a 120Hz refresh rate, and variable refresh rate support. That already gives it one of its biggest advantages over the Steam Deck: the screen is larger, sharper, and smoother. The Steam Deck OLED still wins on contrast and black levels because OLED is OLED, and OLED likes to show off. But for resolution, refresh rate, and motion clarity, the Legion Go S has a very strong case.

Depending on the configuration, the Legion Go S may come with an AMD Ryzen Z2 Go or AMD Ryzen Z1 Extreme processor, integrated Radeon graphics, up to 32GB of LPDDR5X memory, and up to 1TB of PCIe SSD storage. The SteamOS editions are the most interesting because they remove much of the friction that has made Windows handhelds feel like tiny laptops pretending to be consoles.

Key Hardware Highlights

• 8-inch 1920 x 1200 IPS touchscreen
• 120Hz refresh rate with VRR support
• AMD Ryzen Z2 Go or Ryzen Z1 Extreme options
• Integrated AMD Radeon graphics
• 16GB or 32GB LPDDR5X memory, depending on model
• 512GB or 1TB SSD storage, depending on model
• Hall Effect joysticks
• Comfort-focused fixed controller design
• SteamOS or Windows 11 configurations
• 55.5Wh-class battery

On paper, that reads like a modern handheld checklist. In practice, the experience depends heavily on the model you buy. The Windows-based Ryzen Z2 Go version launched with a premium price and received a mixed reception because its performance did not always justify the cost. The SteamOS versions, however, change the conversation. SteamOS makes the device easier to use, quicker to resume, and better aligned with what people expect from a handheld gaming console.

Design and Comfort: Lenovo Got the Grip Right

The original Lenovo Legion Go was powerful and imaginative, but it was also chunky, angular, and not exactly what you would call “snuggle-friendly.” It had detachable controllers, a kickstand, and a huge display, but holding it for long sessions could feel like trying to game on a very confident brick.

The Legion Go S is different. Lenovo traded modularity for comfort, and that was the right call. The grips are rounded, the weight is better distributed, and the fixed controls make the whole device feel more unified. It does not have the quirky Nintendo Switch-style personality of the original Legion Go, but it feels more polished and less experimental.

The buttons are responsive, the triggers feel substantial, and the Hall Effect joysticks are a welcome feature for long-term reliability. Hall Effect sticks use magnetic sensors instead of traditional contact-based mechanisms, which helps reduce the risk of stick drift. Anyone who has watched a character slowly walk left on their own knows why that matters. Stick drift is the haunted-house creak of modern controllers.

Display Quality: The Biggest Steam Deck Upgrade

The screen is one of the clearest reasons to consider the Lenovo Legion Go S over the Steam Deck. The Steam Deck OLED has rich colors and excellent contrast, but its resolution and refresh rate are lower than what the Legion Go S offers. Lenovo’s 8-inch 1920 x 1200 panel gives games more room to breathe, and the 120Hz refresh rate makes menus, indie games, 2D titles, and lighter esports games feel wonderfully smooth.

Variable refresh rate support is also a major advantage. Handheld PCs often live in the awkward performance zone between 35 and 55 frames per second. Without VRR, those dips can look choppy. With VRR, the display can better match the game’s frame output, making imperfect performance feel smoother. It is not magic, but it is the kind of practical feature that makes handheld gaming more enjoyable in the real world.

The one obvious drawback is that the Legion Go S does not use OLED. If you play horror games in a dark room or love the inky blacks of the Steam Deck OLED, Lenovo’s IPS panel will not deliver the same cinematic punch. But for players who prioritize sharpness, refresh rate, and flexibility, the Legion Go S display is a legitimate upgrade.

Performance: Choose SteamOS, Choose Carefully

Performance is where the Lenovo Legion Go S story gets interesting. The device exists in multiple versions, and they are not all equal. The Ryzen Z2 Go model is designed as a more affordable handheld chip, but early Windows-based reviews showed that it could feel underpowered for the price. It can run many modern games at lower settings, but it is not the model that makes the Legion Go S feel like the “best Steam Deck upgrade.”

The stronger case belongs to the SteamOS version with the Ryzen Z1 Extreme. That configuration pairs a proven handheld APU with a smoother operating system and enough memory to handle demanding PC games more comfortably. With SteamOS, the Legion Go S feels less like a compromised Windows machine and more like a purpose-built gaming handheld.

Realistic Game Expectations

For AAA games, expect to make settings adjustments. This is still a handheld, not a desktop tower wearing a tiny backpack. Games such as Cyberpunk 2077, Baldur’s Gate 3, Elden Ring, and Forza Horizon 5 generally benefit from medium-to-low settings, resolution scaling, FSR, and frame caps. The good news is that the 1200p screen still looks clean when running games at lower internal resolutions, and VRR helps smooth out uneven frame pacing.

For indie games, older PC games, emulation-friendly classics, and lighter titles, the Legion Go S feels fantastic. Games like Hades, Dave the Diver, Balatro, Stardew Valley, Dead Cells, and Hollow Knight are exactly the kind of titles that make handheld gaming dangerous to your sleep schedule. “Just one more run” becomes “Why is the sun judging me?”

SteamOS vs Windows: This Is the Whole Ballgame

Windows handhelds are powerful, flexible, and occasionally as graceful as a shopping cart with one bad wheel. Windows can run more launchers, more anti-cheat-restricted multiplayer games, and more non-Steam software. But on a handheld, it often feels cramped. Tiny desktop buttons, pop-up updates, background tasks, driver tools, and login prompts are not what most people want when they are just trying to play a game during lunch.

SteamOS fixes the vibe. It gives the Legion Go S a console-like interface, fast suspend and resume, easy access to Steam settings, controller-friendly menus, and a library experience that feels built for thumbs instead of mouse clicks. This is why the Steam Deck became so popular in the first place. It was not the most powerful handheld; it was the handheld that felt least annoying.

On the Legion Go S, SteamOS makes Lenovo’s hardware shine. The device wakes faster, gets into games more naturally, and avoids much of the Windows clutter that dragged down early impressions of the Windows model. That does not mean SteamOS is perfect. Some multiplayer games with anti-cheat systems still do not work properly, and non-Steam launchers may require extra steps. But for a Steam-first gamer, SteamOS is the obvious choice.

Battery Life: Good Enough, Not Class-Leading

Battery life is the one area where the Steam Deck still fights hard. The Lenovo Legion Go S has a larger battery than the Steam Deck LCD and similar capacity to some other PC handhelds, but its sharper screen and higher-performance ambitions can drain power quickly. Demanding AAA games can bring battery life down to around the one-and-a-half to two-hour range, depending on brightness, wattage, resolution, and frame-rate limits.

For lighter games, the experience is much better. Indie titles and older games can stretch much longer, especially if you lower brightness, cap the frame rate, and reduce the refresh rate. This is where SteamOS helps because its performance controls make tuning easier. A 40fps cap can be the sweet spot for many games, giving you smoother-than-30fps gameplay without burning through the battery like it owes you money.

Battery Tips for Better Results

• Use a 40fps or 45fps frame cap for demanding games.
• Lower the resolution or use FSR when possible.
• Reduce brightness indoors.
• Use lower TDP settings for indie and 2D games.
• Keep 120Hz for lighter games, but do not be afraid to reduce refresh rate for battery savings.

Controls and Audio: Better Than Expected

The Legion Go S feels like a handheld designed by people who actually hold handhelds. The sticks are accurate, the buttons are clicky without feeling cheap, and the triggers offer satisfying travel. The D-pad is suitable for platformers and retro games, though fighting-game perfectionists may still prefer a dedicated controller. The rear buttons add flexibility, especially for shooters, action RPGs, and games with awkward keyboard-heavy layouts.

The audio is also a pleasant surprise. Handheld speakers often sound like someone trapped a podcast inside a soda can, but the Legion Go S delivers fuller sound than expected. Headphones are still best for immersive play, but the built-in speakers are strong enough for casual sessions.

The weak spot is the small touchpad. It is useful in a pinch, but Steam Deck users should not expect the same trackpad experience. Valve’s dual touchpads remain one of the Steam Deck’s most distinctive advantages. If you play strategy games, CRPGs, or desktop-heavy titles, the Steam Deck may still feel more natural.

Lenovo Legion Go S vs Steam Deck OLED

The comparison is not as simple as “newer wins.” The Steam Deck OLED still has major strengths: a beautiful OLED display, excellent efficiency, mature software, great trackpads, and a huge community. It is also often easier to recommend to casual players because Valve controls the full hardware and software experience.

The Lenovo Legion Go S counters with a larger 8-inch display, higher 1920 x 1200 resolution, 120Hz refresh rate, VRR, comfortable ergonomics, and stronger performance potential in the right configuration. If you want the smoothness of SteamOS but wish the Steam Deck had more modern hardware, the Legion Go S is exactly the kind of upgrade you have been waiting for.

Buy the Steam Deck OLED If:

• You want OLED contrast and richer black levels.
• You value battery efficiency above raw performance.
• You love the Steam Deck’s trackpads.
• You want the safest, most mature handheld ecosystem.

Buy the Lenovo Legion Go S If:

• You want a larger, sharper, faster display.
• You prefer SteamOS but want stronger hardware options.
• You care about VRR and smoother frame pacing.
• You want one of the most comfortable handheld PC designs.
• You are choosing the SteamOS model, preferably with Ryzen Z1 Extreme.

Who Should Avoid the Lenovo Legion Go S?

The Legion Go S is not for everyone. If you mostly play competitive multiplayer games that rely on Windows-only anti-cheat systems, the SteamOS version may frustrate you. If you want the longest battery life, the Steam Deck OLED remains a safer pick. If you find the Windows model heavily discounted, it may be tempting, but the Windows experience is still less elegant on a handheld.

The biggest mistake is buying the wrong version at the wrong price. The Ryzen Z2 Go Windows model struggled to justify its premium launch cost. The SteamOS models are the ones that make sense, and the Z1 Extreme SteamOS version is the model that best supports the “Steam Deck upgrade” argument.

Verdict: Is the Lenovo Legion Go S the Best Steam Deck Upgrade?

Yes, with an important condition: the Lenovo Legion Go S is the best Steam Deck upgrade when you buy the SteamOS version that matches your performance expectations. It is not automatically better than the Steam Deck OLED in every category, and it does not erase the Deck’s advantages in battery life, OLED quality, and trackpad control. But it does deliver the upgrade many Steam Deck owners have wanted: a bigger screen, higher resolution, faster refresh rate, VRR, better performance potential, and a familiar SteamOS experience.

The Legion Go S proves that the future of handheld PC gaming is not just about faster chips. It is about the complete experience. Hardware matters, but software decides whether you actually enjoy using the thing. With Windows, the Legion Go S feels like a promising handheld fighting its operating system. With SteamOS, it feels like the Steam Deck went to the gym, got a sharper screen, and learned a few new tricks.

Extended Experience Section: Living With the Lenovo Legion Go S Mindset

The best way to understand the Lenovo Legion Go S is to imagine the daily routine of a Steam Deck owner who loves the Deck but has started noticing its limits. You pick up the Deck, launch a newer game, and suddenly you are bargaining with settings like a tiny graphics accountant. Shadows down. Resolution down. Frame rate capped. FSR on. Please, dear handheld gods, just give me a stable 40fps. The Steam Deck still performs miracles, but modern PC games are not getting lighter. They are arriving with bigger textures, more demanding engines, and menus that seem personally offended by low-power hardware.

The Legion Go S changes that feeling. The larger 8-inch screen immediately makes games feel more spacious. Text in RPGs is easier to read. Map icons are less microscopic. Inventory screens feel less like eye exams. In games with dense interfaces, that extra screen real estate matters. A handheld is only portable if you can actually see what you are doing without squinting like you are decoding ancient runes.

The 120Hz panel also changes how the system feels outside of games. Scrolling through the Steam library, browsing settings, moving around menus, and playing lightweight games all feel more fluid. You may not run every AAA title at 120fps, and expecting that would be like expecting a toaster to host Thanksgiving dinner. But the high-refresh screen still improves the overall feel of the device, especially when paired with VRR.

Comfort is another daily-use win. Long sessions expose bad ergonomics fast. A handheld can look incredible in product photos and still make your hands feel like they filed a complaint with human resources. The Legion Go S avoids that problem better than most. Its rounded grips and fixed controller design make it easy to hold for extended sessions, and the controls sit where your fingers expect them to be. That sounds basic, but in handheld gaming, basic comfort is premium engineering.

SteamOS is the part that makes the experience click. The magic is not that SteamOS runs every game perfectly. It does not. The magic is that it respects the handheld format. Suspend a game, put the device down, come back later, and continue. Adjust performance settings without digging through desktop utilities. Browse your library without wrestling with Windows pop-ups. It feels like a gaming device first and a computer second, which is exactly the right priority.

There are still moments when reality taps you on the shoulder. Some games do not behave on SteamOS. Some launchers are clunky. Battery life can vanish quickly if you let demanding games run wild. And if you love the Steam Deck’s trackpads, the Legion Go S touchpad will feel like a polite suggestion rather than a proper replacement. But the overall experience is strong because it solves the biggest emotional problem with Windows handhelds: friction.

The Legion Go S is at its best when treated as a premium Steam library machine. It is not trying to be a Nintendo Switch. It is not a laptop replacement. It is not a desktop PC. It is a comfortable, powerful handheld for people who already own too many Steam games and would like to ignore their backlog in more rooms of the house. In that role, it shines.

For Steam Deck owners, upgrading to the Legion Go S feels less like switching teams and more like moving into a bigger apartment. The furniture is familiar, the layout makes sense, but suddenly there is more space, smoother motion, and better room for demanding games. That is why the SteamOS Lenovo Legion Go S earns its place as one of the best Steam Deck upgrades available today.

Conclusion

The Lenovo Legion Go S is not flawless, but the SteamOS version is the handheld that finally gives Steam Deck fans a convincing upgrade path. Its larger 8-inch 120Hz display, VRR support, comfortable design, Hall Effect joysticks, and stronger configuration options make it feel more modern than Valve’s handheld in several important ways. The Steam Deck OLED still wins for OLED contrast, battery efficiency, and trackpad control, but the Legion Go S wins for gamers who want a sharper, smoother, more performance-focused SteamOS handheld.

The short version is simple: avoid overpaying for the weaker Windows configuration, choose SteamOS if your library supports it, and strongly consider the Ryzen Z1 Extreme model if performance is your top priority. Do that, and the Lenovo Legion Go S becomes more than another handheld PC. It becomes the Steam Deck upgrade many players have been waiting for.
