- Notifications – You can get notifications from your paired phone for calls, texts, apps alerts and more.
- Quick replies – Both watches allow you to respond to notifications with short preset replies or emojis on Android.

The Sense pulls ahead on smart features due to the onboard music storage and deeper voice assistant integration. But both cover the essential notification and quick reply functionality.
Accuracy
Both Amazfit and Fitbit use proprietary algorithms to process the sensor data. In general, they provide accurate health and fitness tracking compared to medical devices.
For heart rate,tests show occasional inaccuracies during intense exercise by both brands. But resting and walking heart rates are fairly precise.
The SpO2 readings on the Sense and GTS 2 are also quite accurate when compared to a pulse oximeter. You can expect +/- 2% variance in results.
When it comes to step counting, sleep and exercise detection, both watches perform on par with less than 5% error rates under controlled conditions. The Fitbit Sense may have a slight edge for tracking calorie expenditure.
So if accuracy is your priority, either watch can reliably track most health metrics and fitness activities.
Battery Life
With continuous heart rate monitoring and always-on displays, battery life is a concern for these feature-packed watches.
The 340 mAh battery on the Amazfit GTS 2 lasts around 7 days of typical usage. You’ll get around 12 days by turning off the always-on display.
The Fitbit Sense has a smaller battery at 296 mAh which provides 6+ days battery according to Fitbit. Real world usage is closer to 3-4 days for most users.
Battery life depends on usage but the GTS 2 has the advantage here. It can outlast the Sense by a few days on a single charge.
