Zeblaze TS 4 FAQs

Can the Zeblaze TS 4 make and receive phone calls?

Yes. The Zeblaze TS 4 supports Bluetooth calling: once paired with your phone you can answer, reject and make calls from the watch using its built-in microphone and speaker. Keep your phone within Bluetooth range, around 10 metres.

Is the Zeblaze TS 4 waterproof?

It is rated IP68 for dust and water resistance, so rain, sweat and hand washing are fine. Avoid hot showers, saunas, sea water and diving, as heat and pressure can damage the seals.

How long does the battery last?

Expect around 7–14 days of typical use from its 300 mAh Li-Po battery. Bright screens, always-on display, frequent calls and continuous heart rate tracking use more power. See our smartwatch battery life guide for tips.

Does the Zeblaze TS 4 work with iPhone and Android?

Yes, it is compatible with iOS and Android phones via the companion app.

Are the health readings medically accurate?

No smartwatch in this range is a medical device. Heart rate, blood oxygen, blood pressure, temperature and similar readings are estimates to help you spot trends in your general fitness and wellbeing. They are not suitable for diagnosing or managing a medical condition, so always speak to a healthcare professional about health concerns.
