HOW TO FIX IT ???
I installed Watch OS 2 on my Apple Watch a few days after WWDC. Since then the experience of using the Watch was a complete nightmare. I have had many problems including contacts not syncing via my iPhone, not receiving notifications, home screen freezing , the watch running warm against my skin, and worst of all poor battery life. My watch only seem to last 4 hours on a single charge ever since the beta was installed. Even though Apple has not documented a way to downgrade. I decided to try to figure out a solution on my own. I tried many things like downgrading my iPhone to iOS 8.3 to see if I could force a downgrade, nothing happened. I even tried resetting the watch back to factory settings and setting up as a new watch, still nothing happened. The Apple watch app even showed me an alert saying that my iOS was out of date to use the watch. As a final resort i reupgraded my iPhone to iOS 9 just to get the Watch paired up to use, until the next beta or until somebody figured out how to downgrade. After I installed iOS 9 again I noticed the Watch would not pair to my phone using the camera, then I tried the manual pairing options and nothing happened, and no watches were showing in range. From there I tried a bunch of troubleshooting solutions like restarting the phone, the Watch app and turning on and off Bluetooth and nothing seem to fix it.
