When Zepp OS was announced in July, one of the new features the manufacturer revealed the new operating system would bring is an improvement in power consumption. With the launch of the new Amazfit GTR 3 and Amazfit GTS 3, that claim is indeed true as both watches do have better battery life, at least on paper, than their predecessors.
The Amazfit GTR 2 and Amazfit GTS 2 launched with a battery capacity of 471mAh and 246mAh respectively. Surprisingly, the new Amazfit GTR 3 has a smaller 450mAh battery compared to its predecessor while the new Amazfit GTS 3 has a 250mAh battery which is a tad bigger than that of its predecessor. Nevertheless, the Amazfit GTS 3 with its smaller battery capacity, but the same 1.39-inch display size as the Amazfit GTR 2, has better battery life. The Amazfit GTR 3 which has a slightly bigger battery but also a larger 1.75-inch screen compared to its predecessor, the Amazfit GTS 2 whose screen is 1.65 inches, also has better battery life.
The table below shows how the new smartwatches compare to the old ones with respect to battery life:
| Amazfit GTR 3 | Amazfit GTR 2 | Amazfit GTS 3 | Amazfit GTS 2 | |
|---|---|---|---|---|
| Display size and resolution | 1.39 inches AMOLED 454 x 454 | 1.39 inches AMOLED 454 x 454 | 1.75 inches AMOLED 390 x 450 | 1.65 inches AMOLED 348 x 442 |
| Battery capacity | 450mAh | 471mAh | 250mAh | 246mAh |
| Typical Usage | Up to 21 days | Up to 14 days | Up to 12 days | Up to 7 days |
| Heavy Usage | Up to 10 days | Up to 6.5 days | Up to 6 days | Up to 3.5 days |
| Battery Saver Mode | 35 days | Up to 38 days | Up to 20 days | Up to 20 days |
Amazfit GTR 3 vs Amazfit GTR 2
As shown in the table above, the Amazfit GTR 3, even with its smaller battery capacity has an additional 7 days of battery life when compared to its predecessor for typical usage. For heavy usage, it also gets an extra 3.5 days of battery life which is quite impressive. Surprisingly, in battery saver mode, its battery life is 3 days fewer.
Amazfit GTS 3 vs Amazfit GTS 2
The Amazfit GTS 3 has a bigger display than its predecessor and a slightly bigger battery. It is understandable that it has a bigger battery since the larger display means the overall watch is bigger and there should be more space to squeeze in a bigger battery. However, since the screen is bigger and the difference in battery capacity is very small, one wouldn’t expect a significant difference in battery life, right?
Turns out the Amazfit GTS 3 is as impressive in terms of battery life just like its circular sibling. In typical usage mode, its battery life is 5 days more than that of the Amazfit GTS 2. It also lasts for an additional 2.5 days in heavy usage mode when compared to its predecessor. In battery saver mode, both smartwatches have the same battery life.
Zepp OS – A promise delivered
It is pretty nice to see that the promise of better power consumption with the arrival of Zepp OS is not false. Although the details above were pulled from their product pages, we don’t expect a significant deviation, if at all, when the watches are reviewed.
