On the outside, the new Amazfit GTS 4 smartwatch and Amazfit GTR 4 smartwatch are different, but they share many features on the inside.
Zepp Health's new smartwatches are the Amazfit GTR 4 and Amazfit GTR 4, but which one is worth buying? The Amazfit GT series is split into two — the Amazfit GTR line, which has a round-faced dial, and the Amazfit GTS line, which has an Apple Watch-like design. This dual-design strategy allows Zepp Health to cater to those who prefer round-faced watches and those who want a watch with a square dial.
Before the launch of the Amazfit GTS 4, Zepp already announced the Amazfit GTS 4 Mini in July as a successor to the Amazfit GTS 2 Mini. Priced at $119, it packs a bigger display, an improved sensor, upgraded GPS tracking and longer battery life. In addition, the GTS 4 Mini is the first of the Amazfit mini watches to run Zepp OS, which debuted on the Amazfit GTR 3 and GTS 3 in 2021.

The shape of the dial is the obvious difference between the two smartwatches, but there are other similarities as well. The two watches have an aluminum alloy frame, a stainless steel navigation crown, a polycarbonate bottom shell and a 5 ATM water-resistant rating. However, the Amazfit GTR 4 has a secondary button. It also uses 22mm straps, while the Amazfit GTS 4 has 20mm straps. The GTR 4 will be available in Black, Brown and Grey. On the other hand, those who prefer the GTS 4 can purchase it in Black, White, Brown and Pink.
Gracing the front of the Amazfit GTR 4 is a 1.43-inch 466 x 466 display, whereas the Amazfit GTS 4 has a 1.75-inch 390 x 450 display. Both are AMOLED panels with tempered glass protection, anti-fingerprint coating and support for Always-on display. The GTR 4 also has an anti-glare bezel and up to 200 watch faces to choose from, whereas the GTS 4 has 150 watch faces. In addition, both smartwatches feature the BioTracker 4.0, an updated health tracking sensor with four photodiodes and two LEDs that allow for all-day heart rate, SpO2 and stress monitoring. There is also support for sleep tracking and women's health tracking.
The new Amazfit smartwatches support 154 sports modes with smart recognition for up to eight. Users can also create interval training templates directly on the watch for up to 10 sports. As expected, there is a built-in GNSS chip with support for six satellite systems. In addition, Zepp claims the Amazfit GTR 4 and Amazfit GTS 4 are the first in the industry to use a dual-band circularly polarized GPS antenna, which boasts an accuracy of up to 99 percent and is comparable to handheld GPS locators. The new watches also receive an OTA update that supports importing route files with real-time navigation. There is also support for Fall Detection. Amazfit's new watches run Zepp OS 2.0, which brings new apps such as a baby feeding tracker and two mini-games. Like its previous watches, Zepp's new wearables skip the Google Assistant for Amazon's Alexa assistant. There is also an offline voice assistant. They also have built-in storage so that users can store their favorite playlists and audiobooks. A built-in speaker and mic allow for Bluetooth call support. The watches support Android and iOS and connect via Bluetooth 5.0 (BLE) and 2.4GHz Wi-Fi. They also pack a bunch of sensors, including a barometer, a gyroscope, an accelerometer and a compass.
Regarding battery life, the Amazfit GTR 4 has a 475mAh battery that will last up to 14 days on a single charge and up to 24 days in battery save mode. In contrast, the Amazfit GTS 4 has a smaller 300mAh battery that provides up to eight days of use and goes up to 16 days in battery saver mode. In addition, both watches use a magnetic charger and take up to two hours to fully charge. Despite these differences, both smartwatches sell for the same $199/€199 price and are already available in the U.S.
