綜合目前玩家社群的回饋、實機測試結果與長時間使用心得來看，Switch 2雖然在效能與功能上有明顯升級，但也逐漸浮現出一些不可忽視的缺點，特別集中在手把設計與向下相容體驗這兩個層面。

首先是Joy-Con 2的設計問題。Switch 2採用全新的磁吸式軌道結構，取代過去的滑軌卡扣，理論上讓安裝與拆卸更直覺。然而實際使用中，不少玩家反映磁吸力道偏強，加上接合邊緣的設計較為銳利，若在裝卸時角度不正確或操作過快，確實存在夾傷手指的風險。這種情況在單手拆卸或匆忙更換時特別容易發生，對兒童或手較小的玩家來說更不友善。

在長時間遊玩的舒適度方面，也出現分歧評價。Joy-Con 2新增的光學感應器，讓部分遊戲能像滑鼠一樣進行精準瞄準，在射擊或策略操作上相當新鮮，但實測顯示，這種使用方式若持續太久，容易造成手腕與前臂的痠痛。此外，Switch 2本體在重量分配與厚度上的調整，雖然提升穩定感，卻也讓部分玩家在長時間手持遊玩後出現手掌或手指不適的情況，顯示人體工學仍有改進空間。

向下相容方面，Switch 2在讀取Switch一代實體卡匣時，整體體驗並非完全無痛。部分測試指出，在新主機上執行舊遊戲時，可能會出現額外的輸入延遲，操作反應略遜於在原版Switch上直接遊玩。這種差異在節奏快、講求即時反應的動作遊戲中尤為明顯，對習慣精準操作的玩家來說，會有明顯「不對勁」的感覺。

畫面與讀取效能的表現也並非全面升級。由於不少Switch一代遊戲本身解析度較低，在Switch 2的1080p螢幕上被拉伸顯示後，畫面鋸齒感可能更加明顯，色彩表現也顯得偏淡，反而放大原本的畫質限制。雖然主機內建儲存空間的讀取速度確實更快，但若玩家沿用舊款microSD卡，往往因為規格不足，無法發揮新主機的效能，甚至在某些情況下出現卡頓，造成體驗落差。

除了上述重點問題，還有一些較為普遍的缺點逐漸被玩家提及。電池續航力便是其中之一。由於效能提升與高更新率螢幕的關係，Switch 2在高效能遊戲下的續航時間約落在2到6.5小時之間，明顯低於 Switch OLED版可達4.5到9小時的表現，對長時間外出或通勤玩家來說是一項退步。此外，在向下相容測試中，仍約有2.5%的第三方遊戲出現無法啟動或遊戲途中崩潰的狀況，顯示相容性並非百分之百穩定。

螢幕表現方面也存在爭議。雖然Switch 2支援120Hz更新率，但部分測試顯示其反應時間約在33毫秒左右，在快速畫面切換時可能產生殘影感，這對重視畫面清晰度與即時反應的玩家來說，是一個略顯矛盾的設計取向。

如果玩家在使用Switch 2讀取舊卡帶時遇到特別嚴重的延遲或不順情況，較為實際的做法仍是先查閱Nintendo官方支援頁面，確認該遊戲是否列入相容性或效能優化名單，同時也可嘗試清潔卡帶的金屬接點，以排除單純的接觸不良問題。整體而言，Switch 2的缺點並非致命，但確實提醒玩家，這仍是一台需要靠後續更新與配件改良來逐步成熟的新主機。

Based on current community feedback, hands-on testing, and longer-term usage reports, the Switch 2—while clearly upgraded in terms of performance and features—has also begun to reveal several notable shortcomings. These issues are most frequently discussed in relation to controller design and backward compatibility, and together they highlight areas where the new hardware still feels somewhat unfinished.

One of the most talked-about concerns involves the redesigned Joy-Con 2 controllers. Switch 2 replaces the old rail-and-lock mechanism with a new magnetic attachment system that is meant to make connecting and detaching the controllers faster and more intuitive. In practice, however, many players report that the magnetic force is quite strong, and the edges around the connection points are relatively sharp. If the controllers are attached or removed at the wrong angle, especially when done quickly or with one hand, there is a real risk of pinching fingers. This problem is more pronounced for users with smaller hands and for children, making the design feel less forgiving than intended.

Comfort during extended play sessions has also drawn mixed reactions. The Joy-Con 2 introduces an optical sensor that allows for mouse-like precision aiming in certain games, which can feel fresh and responsive at first. However, extended use of this grip style has been shown in testing to cause wrist and forearm fatigue. At the same time, changes to the console’s weight distribution and increased thickness, while improving stability, have led some players to experience discomfort in their palms or fingers after long handheld sessions. These reports suggest that the overall ergonomics still leave room for refinement.

Backward compatibility, one of Switch 2’s major selling points, has proven to be less seamless than many expected. When running original Switch cartridges on the new hardware, some tests indicate the presence of additional input lag. Control response can feel slightly slower compared to playing the same games directly on the original Switch. This difference is especially noticeable in fast-paced action titles that rely heavily on precise timing, where even small delays can feel disruptive to experienced players.

Visual quality and loading performance are also not universally improved. Many first-generation Switch games were designed for lower native resolutions, and when these titles are upscaled to fit the Switch 2’s 1080p display, jagged edges and washed-out colors can become more apparent. Rather than benefiting from the new screen, some older games end up looking rougher due to the magnification of their original limitations. While the internal storage of Switch 2 is significantly faster, players who continue using older microSD cards may encounter bottlenecks caused by outdated standards, occasionally resulting in stuttering or inconsistent performance.

Beyond these core issues, several broader drawbacks are being mentioned more frequently. Battery life is a major one. With higher performance targets and support for high refresh rates, Switch 2 delivers only around 2 to 6.5 hours of playtime in demanding games, a clear step down from the Switch OLED model’s 4.5 to 9 hours. For commuters or players who frequently game on the go, this reduction is particularly noticeable. Compatibility is another concern: roughly 2.5% of third-party titles reportedly fail backward-compatibility testing, either refusing to launch or crashing during gameplay, indicating that support is not yet fully stable.

The display itself has also sparked debate. Although the Switch 2 supports a 120Hz refresh rate, some measurements place its response time at around 33 milliseconds. In fast-moving scenes, this can lead to noticeable ghosting, creating an odd mismatch between the high refresh rate and the panel’s actual responsiveness—an issue for players sensitive to motion clarity.

If players experience severe loading issues or unusually poor performance when using older cartridges, the most practical first step is to consult Nintendo’s official support pages to confirm whether the game is included in the compatibility or optimization list. Cleaning the cartridge’s metal contacts can also help rule out simple hardware connection problems. Overall, none of these shortcomings are necessarily deal-breaking, but they do serve as a reminder that Switch 2 is still a platform that will need time, software updates, and accessory refinements to fully reach its potential.
