Honor has teased an interesting health-related feature for its upcoming 700 series, suggesting that the rear display on the Honor 700, 700 Pro and 700S could do more than simply show notifications and other information.

A few days after officially revealing the designs of all three smartphones, Honor has released a new teaser image showing heart rate and blood oxygen readings on the rear display. This suggests that users could be able to monitor these health metrics directly from the back of their devices. However, Honor has not officially confirmed the feature or explained how it will work.

For the functionality to work, the smartphones would need a dedicated sensor capable of taking the measurements. One possible location is the component positioned above the oval-shaped multi-LED flash on the rear panel, although its actual purpose remains unconfirmed.

According to well-known Chinese tipster Digital Chat Station, the rear display will also offer several additional functions. It could serve as a viewfinder, allowing users to take selfies using the main rear cameras. The screen is also expected to support mini games and display notifications.

Honor has confirmed that all three smartphones will be available in Blue Tone, Cold White, Clear Sky and Pink Mist colour options.

According to previous leaks, the standard Honor 700 will be powered by Qualcomm’s Snapdragon 8s Gen 4 chipset, while the 700 Pro is expected to use the more powerful Snapdragon 8 Gen 5. Both models are also tipped to feature periscope telephoto cameras with teleconverter support.

The Honor 700 Pro is specifically rumoured to feature a 6.57-inch display and a massive 9,000mAh battery.
