With the OnePlus Watch 4, OnePlus is launching a new smartwatch on the market that is characterized by high-quality materials and an exceptionally long battery life. Despite the energy-intensive Wear OS, the model promises up to 16 days of battery life – a value that stands out in this category. In addition to a robust titanium case and sapphire crystal, the watch features modern hardware and extensive health functions.

  • Titanium case and sapphire crystal for high resistance
  • Up to 16 days of battery life in energy-saving mode
  • Wear OS with access to apps, Google Wallet and voice assistant
  • Extensive health and fitness functions including 100+ sport modes

OnePlus Watch 4 impresses with its battery life and premium materials

The OnePlus Watch 4 sets new standards in the smartwatch segment, particularly with its combination of high-quality workmanship and efficient energy management. The case is made of titanium and is water-resistant up to 5 ATM, making the watch suitable for both everyday wear and sporting activities. The robust design is complemented by a scratch-resistant sapphire crystal that reliably protects the display.

Inside is a Qualcomm Snapdragon W5 Gen 1, which is supported by an additional co-processor. This dual-chip architecture enables intelligent task distribution: while the main processor handles demanding applications, the energy-efficient co-processor takes care of background processes. In combination with a 646 mAh battery, the smartwatch achieves a runtime of up to 16 days in power-saving mode. Even with intensive use, around five days are realistic according to the manufacturer – a plausible figure compared to other Wear OS devices.

The built-in LTPO OLED display also helps to save energy as it dynamically adjusts the refresh rate. This keeps the display running smoothly without consuming unnecessary power. Overall, there is a clear focus on efficiency without compromising on the user experience.

Wear OS, health functions and powerful everyday features

With Wear OS, the OnePlus Watch 4 offers access to a broad ecosystem of apps and services. These include contactless payment via Google Wallet and voice control via the integrated assistant. These functions make the smartwatch a versatile companion in everyday life and extend its range of uses well beyond pure fitness tracking functions.

The watch is also extensively equipped in the health area. In addition to a heart rate sensor and measurement of blood oxygen saturation (SpO2), it also has a skin temperature sensor. An integrated 60-second check-up combines this data and provides a quick overview of the current health status. An ECG is also integrated, but is currently only enabled in certain regions, which is not unusual for wearables of this type.

For active users, the OnePlus Watch 4 offers support for over 100 sports modes. This covers a wide range of activities – from classic workouts to specific disciplines. The combination of precise sensor technology and comprehensive software makes the watch a versatile tool for training and health monitoring.

According to initial offers, the smartwatch is priced at around 285 euros, although official details are still pending. In view of the features, this classification in the mid to upper segment seems plausible.

Conclusion

The OnePlus Watch 4 impresses with a rare combination of long battery life, robust construction and modern smartwatch functionality. The battery life of up to 16 days in particular makes a strong statement in the Wear OS sector. Official prices are still pending, but initial offers suggest a price of around 285 euros. Availability has already started.
