The Apple Watch Series 5 is expected to be released in the fall of 2019 alongside the new iPhone. Apple Watch 4 hit the stores a month after it was announced on September 2018, so it’s expected that the Apple Watch 5 will follow the same pattern.

The Apple Watch 4 was a big step forward for Apple’s smartwatches. It had an advanced design, a larger screen and FDA-cleared ECG technology. But the new Apple Watch could be even better.

While Apple Watch 4 is the best smartwatch in the market, it is missing some important features present on some of its competitors, especially in fitness tracking. This is what is expected in the Apple Watch 5 based on current rumors – and the Series 4’s missing features, reports CNet.

According to Apple analyst Ming-Chi Kuo, Apple may be set to introduce a new ceramic casing design on at least one model.

Kuo also believes Apple may make its Series 5’s ECG monitor available to more countries, although that may also be a software upgrade for the Apple Watch 4 – as well as a new charging option.

Apple filed a patent for a sensor that can monitor what’s in the air. CultofMac believes this sensor could be used to track your body odor and even air quality. In addition to notifying you about your bad breath, the sensor could also be used to detect low blood sugar levels.

It has also been reported that Apple is working on a sleep tracking feature; which means Apple Watch 5 might finally be able to track your sleep without you needing to download a third-party app.

Price of the new Apple Watch 5 isn’t known at this time, but pricing will probably remain similar to the Series 4. “Pricing will likely start at $399 and go up for the 44mm size or stainless steel. LTE versions are expected to be available for users who want to data access (for services like Apple Music). Colors will likely remain similar to the previous model and existing bands will likely remain compatible with the new watch,” according to CNet.
