Samsung is actively researching the feasibility of introducing a dedicated smartphone liquid cooling system to its Galaxy lineup in an effort to combat severe device heating and unlock higher sustained hardware performance. The initiative is a direct response to the thermal challenges posed by modern heavy workloads, including advanced mobile games and on-device AI applications.
Reports from Korea Sisa Journal-e show that Samsung Production Technology Research Institute has assembled a dedicated team focused entirely on active thermal management. The group is researching both air-assisted and liquid cooling designs, with the goal of integrating these active systems into future Galaxy smartphones. While standard liquid cooling relies on fluid circulation to carry heat away, active air systems use miniature internal fans to force cool air over components.
Active fan systems are highly effective at dropping surface temperatures rapidly, but they introduce notable engineering trade-offs, including increased handset weight, physical bulk, and audible fan noise. Smartphones also face strict waterproof sealing constraints, which makes it incredibly difficult to route heat from the processor directly to an active liquid or air radiator. As a result, most current designs combine a passive vapor chamber or liquid loop with an external or dual-stage active module.
Several Chinese brands have already experimented with hybrid designs to avoid Galaxy thermal throttling issues. For example, Nubia has shipped gaming phones featuring built-in micro-fans alongside vapor chambers, while iQOO has deployed active external cooling accessories. However, Samsung senior researcher Park Min noted that their current focus is to design a pure liquid system without fan assistance, as mechanical fans inevitably introduce unacceptable noise and durability limits.
Thermal management is becoming the primary bottleneck for mobile hardware. Samsung previously faced severe criticism in 2022 when its Game Optimization Service (GOS) aggressively throttled the Galaxy S22 series to manage heat, while Apple had to patch thermal bugs on the iPhone 15 Pro and 16 Pro lines. As on-device AI and gaming graphics demands increase, the link between temperature and performance is more critical than ever. According to Park, Apple is also patenting active thermal designs, indicating that commercial deployment of advanced active cooling is not far off.
