Huami releases the Amazfit GTS 2e and GTR 2e with AMOLED displays, improved battery life and SpO2 sensors

After the Amazfit GTS 2 and GTR 2 comes the GTS 2e and GTR 2e. As their names suggest, the GTS 2e and GTR 2e are cut-down versions of the smartwatches that Huami released earlier this year. However, not a lot has been cut from the 'e' models. Huami has removed the Wi-Fi module and the option of storing music directly on each smartwatch, but that is it.

Correspondingly, the GTS 2e and GTR 2e use Bluetooth to communicate with a paired smartphone. The smartwatches also have Huami's BioTracker 2 installed, which allows them to read heart rates and measure blood oxygen saturation levels. Additionally, both support sleep tracking and are water-resistant up to 5 ATM.

The GTS 2e and GTR 2e do look different, though. The former has a rectangular AMOLED display that extends to 1.65-inches and has a pixel density of 341 PPI. On the other hand, the GTR 2e has a circular display with a pixel density of 326 PPI. Both smartwatches offer double the battery life of their regular counterparts. The GTS 2e will last up to 14 days on its 246 mAh battery, while the 471 mAh capacity of the GTR 2e should give it 24 days of usage between charges. All other core features of the GTS 2 and GTR 2 return. Huami has added a temperature sensor to its 'e' models, though.

The Amazfit GTS 2e and GTR 2e retail for CNY 799 (~US$122) in China. There is no word yet on whether Huami plans to release the two smartwatches globally, but we would not be surprised if it eventually did.
