I have install iOS 9.0 in my iphone 6 and OS 2.0 on apple watch.
But I plan to downgrade iphone 6 to iOS 8.3. But I am afraid of connection between apple watch and iPhone.
Can anyone give me some suggestions ?
Can Apple Watch with OS 2.0 can connect with iPhone 6 with iOS 8.3 ?
It is not possible to pair an Apple Watch with OS 2.0 and an iPhone running 8.3. I just tried it 🙂
Thank you ! I just want to test my app on IOS 9. But the battery is draining out so fast ! But I found that change the battery setting to Low power mode has a little help about battery life !
