Compare Apple Watch Series 11 vs OnePlus Watch 3

5G/cellular connectivity is considered useful for phone-free use and more efficient data access, but several reviewers see it as situational rather than a universal reason to upgrade.

LTE connectivity was the clearest missing smart feature, repeatedly criticized as absent.

The ECG feature receives strong support from a reviewer’s real family example where on-watch ECG readings caught an irregular rhythm missed elsewhere.

ECG was a major regional caveat: reviewers liked or valued the feature where available, but repeatedly criticized its absence in the US or North America.

Fit is generally good thanks to slimness and size choices, though one reviewer with smaller wrists found the larger case somewhat big.

Fit was the main ergonomic weakness, especially for smaller wrists or lug geometry, though the 43mm model improved this for some reviewers.

Contactless payments worked well where reviewers tested or discussed Google Wallet and NFC payments.

Blood oxygen tracking is treated as a welcome restored capability that makes the watch feel more complete as a health device.

Blood oxygen readings were limited in coverage but strongly positive where tested against reference readings.

Touchscreen responsiveness is good in normal use, but one runner found the curved screen harder to tap while moving.
