Apple's upcoming Apple Watch upgrade will feature the ability to monitor the wearer's mental health and sleep patterns, according to Twitter user Nikias Molina.

Molina says the Apple Watch Series 6 will offer sleep tracking, longer battery life, a pulse oximeter (used for measuring oxygen saturation), an S6 chip and a new feature to monitor "Mental Health Abnormalities". How the latter will work is currently unclear.

Molina is not known for Apple leaks, but his information in this case has been confirmed by Jon Prosser, who is. (Prosser correctly called the iPhone SE launch.) Molina also says he has more to reveal soon.
