Apple watch

Apple's Spring Forward conference is scheduled for March 9 local time. Although Apple Watch has been released for nearly half a year, the details about this product are still unclear. 9to5Mac has obtained a series of new information through the news source.
What is the battery life?

Previous reports said that the Apple Watch could only last 2.5-4 hours under heavy use, but new information reveals that Apple has improved the device's battery life to about 5 hours under heavy use. With mixed active and passive use, it can last for a day, but it will never last until the next day.

The New York Times reported that Apple Watch will provide a power saving mode called Power Reserve, which can disable various services to improve the battery life of the watch. 9to5Mac's sources said that the power saving mode can be activated through the battery Glance and can be turned on at any power level. When turned on, the screen will dim, communication with the iPhone will slow down, and the screen will go out in 1-2 seconds.

Apple Watch will not pop up a window to remind you that the battery is low like the iPhone. When the remaining power is 20%, the battery life Glance will turn orange, and it will turn red when it is less than 10%.
Is there a heart rate sensor?

The Heart Rate Glance feature is a feature that Apple has not yet announced. Thanks to the heart rate sensor, the Heart Rate Glance of Apple Watch can display the heart rate in any situation. When you access the Glance, a heart-shaped pattern similar to the one in the picture above will appear. Pressing the button will start the measurement. The screen will not constantly update the BPM index. The source said that the measurement process is almost real-time and the data is quite accurate.
What is Glance? Are there any notifications?

Glance is a quick view feature in Apple Watch that extracts important information from apps and presents it in a concise form. Glance uses a pull mechanism rather than a push mechanism.

In addition to glances for heart rate and battery life, Apple Watch also includes glances for health data, activities, clock, weather, music, quick settings, calendar and maps by default.

In addition, the Apple Watch also has a notification system similar to the iPhone, which is also accessed by sliding down from the bottom of the screen.
How much storage space is there?

Apple Watch can store and play music without being connected to an iPhone. It is reported that the storage space of the Apple Watch prototype is 8GB and it also includes a Lightining interface, but the official version will not include this interface.
Can I set up my watch using my iPhone?

As previously reported, Apple has launched a companion app for the Apple Watch. Just like Android Wear requires corresponding app pairing settings, users need to turn on the phone's Bluetooth to connect to the Apple Watch and then make settings in the app to adjust the interaction between the watch and the iPhone.

Users can set the icon layout by long pressing and dragging on the iPhone companion's simulated interface. When users download an iPhone app that supports WatchKik, the app will be automatically installed on the Apple Watch.
What is Force Touch? Is there Siri?

Apple Watch can not only recognize every touch, but also sense the force. Force Touch technology enables the screen to sense the difference between tapping and pressing.

Sources praised the screen, which comes with Force Touch technology.

Voice and taps are the input methods of Apple Watch. There is no Siri on Apple Watch, only "Voice Control".
How is the performance? How many apps can be installed?

Previous reports have said that the performance of the S1 chip in the Apple Watch is comparable to that of the A5 chip in the iPhone 5, which means that the processing power of the Apple Watch is close to that of the first-generation iPod touch and the device runs very fast.

However, on the Apple Watch, sources said that an Apple Watch with 200 WatchKit apps installed was very laggy.
How to turn off Apple Watch?

Apple Watch does not have a power button. Sources revealed that users can long press the "communication" button on the right side of the watch to turn it off.
