Is the Huawei Watch D3 more accurate than the D2 for blood pressure?

No. Both use the same cuff-based oscillometric mechanism and the same differential pressure sensor. Huawei has not claimed any accuracy improvement; the D3’s changes are in software features and case comfort, not measurement accuracy.

Is the Huawei Watch D2 still worth buying at a discount?

Yes, if cuff-based blood pressure monitoring is the only feature you need. The core measurement is identical to the D3. You lose the pre/post-exercise mode, Pulse Wave Arrhythmia Analysis, and Health Community sharing, none of which exist on the D2 at any price.

What does the Huawei Watch D3 add that the D2 doesn't have at all?

A dedicated pre- and post-exercise blood pressure mode, Pulse Wave Arrhythmia Analysis for A-fib alerts, a separate Beat-by-Beat ECG app, and a Health Community feature for sharing health alerts with family members.

Is battery life better on the Huawei Watch D3?

No. Both watches quote up to 6 days of typical use, falling to 1 day with 24-hour ABPM enabled. The figures are identical despite the D3’s thinner case.
