From the unknown Sony Smart Watch, to Pebble, to Gear, smart watches are probably blamed most for their ungrounded air. The ultra short endurance and the dial to be awakened are the worst hit areas of the slot point. And today we are going to evaluate , which is a product improved for these two problems.

WeLoop Xiaoheiguo uses Sharp's Memory LCD screen to give the machine three weeks of endurance, while keeping its dial constantly bright at the expense of giving up color display and touch control functions.

Its screen and e-ink features are very similar: power saving, black and white, no light, and only refresh will consume power. But the difference is that it can provide a refresh rate of 60 times per second, and there is no e-ink residue phenomenon. It can be used to play animation or even video. Let's see what changes this new screen technology can bring to smart watches.

hardware component

The packaging of WeLoop Xiaohei matches its name very well - real black. Inside the package are the watch body, instructions and charging line ▼

The charging line has a magnetic suction design similar to that of Macbook, which can be automatically connected after scanning. The magnetic force is moderate ▼

The screen does not light up, the resolution is 144 * 168, and the normal distance is relatively fine ▼

The upper part of the left side of the meter body is equipped with a magnetic charging port, and the lower part is a return button ▼

The charging port has obvious depression to facilitate the docking of magnetic sockets ▼

The right side of the table body is the up and down key and the confirmation key ▼

The logo of WeLoop and five signs of atmospheric pressure waterproof are printed on the back of the surface (that is, it can work normally under the water depth of 50 meters) ▼

The physical size of the dial is 45 * 34.5 * 11mm, which translates into human words. It is similar to the general electronic watch and is one circle smaller than the mountaineering watch ▼

The frosted silicone material of the watch strap feels good, and the snap ring of the metal part is coated with black coating ▼

The appearance of normal wear reminds the author of the electronic watch he bought temporarily for the college entrance exam ▼

Software

If the particularity of its hardware comes from Sharp's Memory LCD screen, the particularity of its software comes from its mobile phone free design idea. Its core functions, such as time and step counting, can work independently of the mobile phone, and even viewing movement data can be completed by the watch itself.

Its client is only responsible for a few functions such as filtering message push and OTA firmware upgrade, which can be downloaded through major application markets ▼

As a watch, the most important thing is the dial. The current version supports the following four dials. It is said that it will add animated effects, team logo, cartoon, facial expression and other characteristic dials through OTA in the later stage ▼

Click the OK button on the right side to enter the function interface, which uses two screens to place eight function items. The first screen is Bluetooth connection, music, camera control, sports health ▼

The second screen is message notification, system settings, time and date, version information ▼

It supports Bluetooth 4.0, Android 4.3 and iPhone 4 and above devices. Users can click the corresponding Bluetooth ID name of the device in the official app to complete the connection ▼

After entering the bound device, you can also use the Find function to make the phone sound, which is used to reverse find the phone that has been lost in the corner. It is said that the anti loss function can also be added later through OTA (that is, if the distance between the phone and the watch exceeds a certain range, the user will be reminded) ▼

Set the second item as music playback control. As the name implies, it is to directly view the songs in the phone in the watch, and perform routine operations such as selecting songs, playing songs, and cutting songs ▼

Its photo function is actually a remote control phone shutter. After the phone opens the app, the watch can control the phone to take photos and route, and each shot will remind the user with a vibration ▼

The step counting function is placed in the fourth item of the setting, which can maintain a 2-week life after being turned on. All data will be directly displayed here, without the need for mobile phones to view. It includes steps, calories and walking distance. The upper right corner is the date. You can switch to other dates from left to right, which can record the movement data of the last week. Data older than that can be viewed through the official WeLoop health assistant client, which will also be automatically uploaded to the cloud for backup ▼

In fact, the author thinks that the most practical feature of a smart watch is the notification reminder function, which will automatically push the notification in the mobile phone notification bar to the watch, and display the source and details of the notification (limited by the size of the screen, sometimes some news information is too long and half can't be seen). It even displays the location of the incoming call, which should be good news for Apple devices that cannot upgrade iOS8 ▼

The seventh item on the second screen is the setting menu, which includes backlight, shake display, night mode (that is, whether to turn on backlight), motion counting and language control item ▼

The penultimate item is the time setting, and the user can manually calibrate the time ▼

Finally, the machine information such as version and serial number ▼

summary

WeLoop Xiaohei is one of the smartwatches used by the author, which is the most like a watch (nonsense) and the most grounded. Many similar products have added the function of step counting, notification pushing, and even photographing, but they all have two fatal problems: one is that the time is not always displayed, which requires action or click to wake up, and there is always one more step psychologically; The second is the sensitive endurance. Limited by the battery technology, the volume, weight and endurance cannot be both.

Faced with these two problems, Sharp's Memory LCD screen played the role of "saving the world". It sacrificed the strong endurance of color display to make the small black battery with only 110mAh battery last for three weeks.

In the process of use, the most frequently used function is the notification function, in addition to watching the time. Mobile phone alarm clock, calendar notification item, telephone, SMS, etc. can be reminded and viewed by shaking the watch, which is very useful when squeezing the subway or when the mobile phone is hidden deep in the bag. The biggest problem is that the current client has not yet improved the notification filtering function, and the game and system information often "shock" me, causing some trouble. But it is said that this function will be added in the near future.

As for the step counting function, it's basically just a matter of wearing it and starting to work. Users just need to check their exercise volume every day, or use the client to show off in the circle of friends. It is said that it will add functions such as running and fitness trainer to its client later.

Considering that few people will sleep with watches, the sleep recording function is not included for the time being, but this function can be easily pushed through OTA, so the self quantifier can not be crazy about it.
