Advantage Of The Amazfit Watch

As for why you would prefer the Amazfit GTR over some other name brand, full-featured smartwatch from the likes of Samsung or Huawei, to name a few significant players, the answer is pretty simple – battery life.

We already have too many devices that need charging in our lives. Out of all the wearables this reviewer has tested throughout the years, only three ever managed to stay on his wrist for more than a few weeks – a few Mi Band iterations, the Amazfit Bip and now the Amazfit GTR. Not having to worry about a frequent charging routine is the most essential thing to look for in a modern wearable wristwatche.
