Overview
- OnePlus posted the Watch 4 on its global site Wednesday with full specs but no price or release date.
- The watch runs Wear OS 6 under OxygenOS Watch 8 on a Snapdragon W5 paired with a BES2800 co‑processor, and it supports Gemini voice access and Google Assistant.
- OnePlus claims a 646 mAh battery lasts up to five days in smart mode and up to 16 days in power saver mode, with a full charge in about 75 minutes at 7.5W.
- The 47 mm model shifts to an all‑titanium case that is lighter and thinner, adds IP69 alongside 5ATM and IP68, and uses a 1.5‑inch LTPO OLED rated at 3,000 nits under sapphire glass.
- Reports describe an incremental update that closely mirrors Oppo’s Watch X3, while coverage also notes conflicting information on ECG support and uncertainty over regional rollout as OnePlus reviews its business.
