One of the best things about the Apple Watch is how it interacts with your iPhone. It’s a conduit to your phone, allowing you to check messages, interact with apps and even access system-level settings without pulling your iPhone out of your pocket. While you can do a lot on your Watch, you can’t do everything, and one missing feature is the ability to check the battery of your iPhone using your Watch.
Apple Watch Help
One of the handy features of the Apple Watch is the ability to read the emails on your wrist, so you don’t have to remove your iPhone from the pocket or bag. It is not ideal to read a long email on your Apple Watch, but perfect to read short emails.
Apple: Apple Watch won’t measure heart rate every 10 minutes when you’re in motion or your arm is moving
We noticed that Apple Watch had stopped recording the heart rate every 10 minutes after installing the Watch OS 1.0.1 update.
The update process is quite different compared to other iOS devices, as you need to download the update on the Apple Watch via the iPhone. Since it seems to rely on a Bluetooth connection to transfer data, it can take quite sometime (20-30 minutes) to install the update.
Apple Watch comes with Wi‑Fi (802.11b/g/n 2.4GHz) support, which is extremely useful as it helps in extending the range between your iPhone and Apple Watch rather than just relying on Bluetooth.
