What are the practical functions if you don't connect the iPhone Apple Watch?

1. Track your movements. Without the iPhone by your side, all the activity tracking functions of Apple Watch will work as usual, except that you can't sync data back to health applications and networks until you connect to the iPhone again. Apple Watch will remind you to stand up and exercise every once in a while, urge you to complete your running goals and so on. So, you can run without a cell phone. Without a cell phone, you can't track the GPS position. 、

2, play music, Apple Watch can be used to control music playback on the iPhone. However, due to the limited storage space of this watch itself, it is difficult to listen to songs without a mobile phone for a long time.

Select a song list on the iPhone's Apple Watch app in advance, and it will synchronize. Since Apple Watch does not support playing music through its integrated speakers, you must first configure Bluetooth headsets.

3. Check the old information. Apple Watch can't receive new information without connecting to the iPhone-because it can't connect to the data network-but that doesn't mean that your old information will be lost. This watch will cache many recently received emails, iMessage and SMS messages. Therefore, if necessary, you can still bring up important information to consult.

4, payment checkout, as long as you use the iPhone to establish an Apple Pay voucher, your Apple Watch can pay independently. A security token to prove your identity is stored on the watch, but as a security measure, it will only take effect when the watch touches your skin (if you take off the watch, you must reconnect your iPhone).

5, browse the photo album, just like music, Apple Watch has no space to store photos. However, if you want to browse your most cherished photos anytime and anywhere, Apple Watch can still give you what you want. By default, my favorite albums on my iPhone are synced to Apple Watch. You can also adjust it through the Apple Watch app on your mobile phone: it may be the best choice to make a special album for watch photos.

6. Use the passbook application. At present, only applications developed by Apple can run on Apple Watch, which is independent of iPhone. Including the passbook. When necessary, you can directly call up the movie tickets, membership cards and vouchers stored in the Passbook app on your wrist, even if your smartphone is not on you. By the way, when the new generation system iOS 9 comes out in autumn, Passbook app will be renamed Wallet.

7. Set the alarm clock and timer. When the iPhone is not connected, various common watch functions on the Apple Watch can still be used as usual. For example, even if your mobile phone is dead at night, or you don't know where it is, your alarm clock will still ring on time. After the launch of WatchOS 2, you can get a good bedside table mode, and Apple Watch will be more able to be used as a small alarm clock. Other related functions, such as watch timer and stopwatch function, can be used as usual when iPhone is not around.

Give the right time

8. Even without the iPhone, the watch function of Apple Watch works as usual. Moreover, Apple promises that the time difference between the device and the global standard time will not exceed 50 milliseconds. The only thing you need to worry about is that the battery is dead.
