Apple Watch Ultra 4, sold on October 22 in Vietnam, has no change in design but has major upgrades in hardware, heart rate sensor and body recovery scoring.

Ultra 4 (right) is also greatly upgraded compared to Ultra 3 in terms of health monitoring capabilities, including a new optical and electrical heart rate sensor system that can continuously monitor heart rate in the background, taking data every 5 seconds. As for the sensor, this is Apple's big addition after a long time with the "32-blade design" bottom surface - spoke lines radiating from the electrode to help the measurement system be much more accurate.

The product runs on the new S11 chip, capable of local AI processing on the device, serving a number of new smart Siri features including sound recognition, such as sirens, doorbells, baby cries; Live Rewind allows you to review the last 15 seconds of conversation in text format; and Siri summary (Siri Recap) helps summarize the conversation.

However, the new Siri features do not yet support Vietnamese and need to wait for the update to be completed after sale.

Watch Ultra 4 has a strong upgrade in battery life. Apple does not announce the capacity, instead the actual usage time is 50 hours in normal use mode, 8 hours more than the predecessor (an increase of 19%), and 84 hours in economy mode, 12 hours more than Ultra 3.

The device is priced from 23.9 million VND for the Alpine, Trail and Ocean wound versions, while the Milan Titan wire version has a higher price of 26.9 million VND.
