OnePlus Watch 3 (Obsidian Titanium, Emerald Titanium)

How long does the OnePlus Watch 3 battery actually last?

The watch provides up to 120 hours of use on a single charge, which equals five full days. This exceptional battery life comes from the dual-engine architecture that optimises power consumption. In real-world testing, users report getting 4-5 days with typical usage including notifications, health tracking and occasional app use. Heavy users with always-on display and frequent GPS usage can expect 2-3 days between charges.

What health metrics can the watch track?

The watch monitors heart rate continuously throughout the day, measures blood oxygen levels (SpO2) and provides detailed sleep analysis including sleep stages and quality scores. It also tracks steps, calories burned, workout intensity and recovery time. The advanced sensors work 24/7 to build a complete picture of your health, offering personalised insights and recommendations based on your individual patterns and goals.

Is the watch compatible with iPhone?

Yes, the OnePlus Watch 3 works with iPhone through the Wear OS app, though some features may be limited compared to Android integration. iPhone users can receive notifications, use Google apps, track fitness metrics and access most core smartwatch functions. However, features like responding to messages directly from the watch and some Google Assistant functions may not work as seamlessly as they do with Android phones.

How durable is the sapphire crystal display?

Sapphire crystal is extremely durable, rating 9 on the Mohs hardness scale, making it virtually scratch-proof in normal use. Only diamond and a few other materials can scratch sapphire crystal. This means the display will maintain its clarity and appearance even after months or years of daily wear. The crystal also provides excellent optical clarity and light transmission for crisp, clear visibility in all lighting conditions.

What's included in the 32GB storage?

The 32GB storage holds the Wear OS operating system, pre-installed apps and leaves space for additional apps, music, photos and personal data. You can download apps directly from the Google Play Store, store offline music for workouts and keep photos on the watch. The generous storage capacity means you won't need to constantly manage space or delete apps to make room for new ones.

How accurate is the GPS tracking?

The dual-band L1+L5 GPS system combined with multiple satellite networks (Beidou, Galileo, GLONASS, QZSS) provides highly accurate positioning, typically within 1-3 metres. This multi-satellite approach ensures reliable tracking even in challenging environments like dense urban areas or under tree cover. The enhanced accuracy is particularly beneficial for running, cycling and hiking where precise distance and route tracking are important.

Can I make phone calls through the watch?

Yes, the watch supports Bluetooth calling when connected to your smartphone. You can answer incoming calls, make outgoing calls using voice commands or the dial pad and the built-in speaker and microphone provide clear audio quality. The watch essentially acts as a Bluetooth headset, routing calls through your phone's connection whilst providing the convenience of hands-free operation.

How fast does the watch charge?

The watch charges rapidly, reaching 80% capacity in approximately 30-40 minutes. A full charge from empty takes about 60 minutes using the included magnetic charging cable. The fast charging capability means you can quickly top up the battery during short breaks, such as showering or getting ready in the morning, without significantly impacting your daily routine or sleep tracking.
