Interestingly, the device may not run Google's Wear OS. Instead, Samsung could use a simpler operating system that focuses more on battery life.According to Sammobile, the new wearable is being developed under the codename Galaxy Aero. References to the device were found in Samsung's Galaxy Wearable app, where it appears to be identified as a watch running an RTOS, or Real-Time Operating System.Galaxy Aero could focus on battery lifeRTOS is a simpler operating system commonly used in affordable fitness trackers and smartwatches. Unlike Wear OS, it does not require as much processing power, which can help devices offer much longer battery life.This means the Galaxy Aero could potentially last for around a week on a single charge. However, the exact battery capacity and battery life of the device are not known yet. The Galaxy Wearable app also refers to the device as "galaxy_rtos_watch", suggesting that it will have a screen and could offer more smartwatch-like features than Samsung's fitness bands. However, it is not clear whether the display will be round, square or rectangular.Since the device is expected to be priced above the Galaxy Fit 4, Samsung could also equip it with some standard smartwatch sensors, including a heart-rate sensor, accelerometer and gyroscope.Galaxy Aero could sit between Galaxy Fit 4 and Watch FE Samsung's wearable lineup currently includes fitness-focused devices as well as more feature-rich Galaxy Watches. The new wearable could fill the gap between the Galaxy Fit 4 and Galaxy Watch FE, offering more features than a fitness band while keeping the price lower than a full-fledged Galaxy Watch.However, there are still several unanswered questions. Samsung has not confirmed the device, its specifications, price or launch date. Galaxy Aero is also believed to be an internal codename, so the final product could arrive with a different name.For now, the biggest takeaway is that Samsung appears to be exploring a smartwatch that prioritises long battery life and essential smartwatch features over the wider app support offered by Wear OS. And Samsung hasn’t revealed any information about the purported Galaxy Aero, so we suggest taking it with a pinch of salt.- EndsPublished On: Aug 7, 2026 14:07 IST
