Amazfit T-Rex Dual Solar leak points to 180-day battery life and rugged outdoor features
Amazfit may be preparing to launch one of its most ambitious outdoor smartwatches yet. A new leak suggests that the upcoming Amazfit T-Rex Dual Solar could bring a unique dual solar-charging design, rugged premium materials, advanced navigation tools, and battery life that may stretch up to 180 days under ideal sunlight conditions.
The leaked information reportedly comes from a Spanish retail listing that briefly appeared online before being removed. While Amazfit has not officially confirmed the device, the details point to a smartwatch designed for hikers, athletes, explorers, and anyone who wants long-lasting performance away from a charger.
The biggest highlight is the rumored dual solar-charging system. Unlike many solar-powered smartwatches that rely mainly on a panel around or beneath the display, the Amazfit T-Rex Dual Solar is said to use photovoltaic panels on both sides of the watch. A larger ceramic-glass solar panel is reportedly built into the back of the case, allowing the watch to collect sunlight from the rear as well as the front.
If accurate, this setup could make the T-Rex Dual Solar stand out in the rugged smartwatch market. Previous leaks also suggested separate solar panels for the display side and the case back, while regulatory details have reportedly connected the device to model number A2570.
The smartwatch is expected to feature a 1.32-inch AMOLED display with peak brightness of up to 3,000 nits. That level of brightness would make the screen easier to read in direct sunlight, an important feature for outdoor users who rely on maps, workout stats, and alerts while on the move.
Durability also appears to be a major focus. The leaked specifications mention a titanium case, sapphire crystal protection, and physical buttons. These features would help the watch handle tough conditions where touchscreens can be difficult to use, such as rain, snow, mud, or while wearing gloves.
The Amazfit T-Rex Dual Solar is also rumored to operate in extreme temperatures ranging from -30°C to 70°C. That would make it suitable for harsh winter hikes, desert adventures, mountain trips, and other demanding environments. An LED flashlight with a boost mode is also said to be included, giving users a handy emergency or low-light tool directly on the wrist.
For navigation and outdoor tracking, the leak claims support for six satellite positioning systems. The watch may also include wrist-based maps, weather alerts, barometric pressure warnings, heart-rate tracking, blood-oxygen monitoring, and advanced training metrics.
These features suggest Amazfit is targeting serious outdoor users, not just casual fitness tracking fans. With map support and environmental alerts, the T-Rex Dual Solar could be useful for trail running, hiking, camping, cycling, climbing, and long-distance endurance activities.
Battery life is where the leaked Amazfit T-Rex Dual Solar becomes especially interesting. The watch is said to deliver around 25 days of typical use on a single charge. In an outdoor mode with hourly GPS updates, battery life could reportedly extend to about 40 days.
However, the most eye-catching claim is the potential 180-day battery life with regular exposure to bright sunlight. This figure appears to rely heavily on the rear solar panel and ideal charging conditions, so real-world endurance will likely vary depending on sunlight exposure, usage habits, GPS activity, display brightness, and sensor tracking.
Still, even if actual results fall below the maximum claim, a dual-sided solar system could give Amazfit a strong advantage in the outdoor smartwatch category. Many adventure watches already offer impressive battery performance, but a rear solar panel could help extend usage during long trips where charging access is limited.
The rumored 180-day endurance would also position the T-Rex Dual Solar as a direct rival to premium expedition-focused watches from Garmin and other outdoor wearable brands. For users who prioritize battery life, durability, and navigation features, this could become one of Amazfit’s most compelling releases.
It is important to treat these details as unofficial for now. Amazfit has not announced the T-Rex Dual Solar, and leaked specifications can change before launch. Pricing, release date, software features, regional availability, and final battery performance remain unknown.
If the leak proves accurate, the Amazfit T-Rex Dual Solar could be one of the most exciting rugged smartwatches of the year. With a bright AMOLED display, titanium construction, sapphire glass, extreme temperature resistance, six-system satellite tracking, built-in flashlight, and a potentially game-changing dual solar-charging design, it may appeal strongly to outdoor enthusiasts looking for a smartwatch that can last far longer between charges.
