  • Specs and images of the Amazfit T-Rex Pro 2 and Amazfit Vienna have leaked.
  • Both are rugged smartwatches with massive batteries.
  • The Vienna is a more premium device with a titanium and sapphire glass build.

Two new Amazfit watches are on their way, or so a new leak from GSMArena would have us believe. Huami, the maker of the Amazfit wearables, may be looking to expand its rugged smartwatch portfolio with the Amazfit T-Rex Pro 2 and Amazfit Vienna.

The two smartwatches are said to come with almost identical specs. However, the Vienna is meant to be a more premium product with a titanium unibody casing and sapphire glass screen.

Their headlining feature is a 500mAh battery. That sort of capacity is pretty rare to find in a smartwatch. We can only think of the TicWatch Pro 3 as another example, but it boasts an even bigger 577mAh battery.

Nevertheless, the T-Rex Pro 2’s 500mAh cell promises up to 24 days of mixed usage between charge cycles. Heavy users can expect about 10 days of uninterrupted on-time. The Amazfit Vienna is expected to deliver 14 days of use.

The T-Rex Pro 2 resembles its predecessor with a thick shell, screws at the top and bottom, and a plastic build. However, Huami is updating it with a bunch of new colors, including an ASTRO Black and Gold option alongside Wild Green and Desert Khaki.

The display size hasn’t changed much. It’s a 1.39-inch AMOLED screen with a 454 x 454 resolution. Like the T-Rex Pro, the new model features 10ATM water resistance, so it should be good to go swimming with you. It also boasts 15 military-standard durability certificates.

Amazfit is upgrading the sensors in the T-Rex Pro 2, so perhaps that’s where the real difference lies between it and the previous model. You’ll now get the BioTracker PPG 3.0 sensor for heart rate and blood oxygen measurement. The device will also feature over 150 sports modes, up from 100 activity modes on the T-Rex Pro.

Elsewhere, you’ll get built-in GPS and Bluetooth 5.0 connectivity. The watch will also bring 32MB RAM and 512MB onboard storage.

The Amazfit Vienna will settle for a smaller 1.29-inch AMOLED display with a 416 x 416 resolution. As per the leak, it gets the same fitness and sports tracking features as the T-Rex Pro 2. However, it ups the water resistance to 20ATM and onboard storage to 4GB.

There’s also built-in GPS here but no eSIM connectivity.

Both smartwatches are tipped to launch this summer, but there are no details on pricing and availability.
