Today, I will experience a different smartwatch with you all-Vivo Watch 2 with ultra-long battery life. When the battery life of the same type of call smartwatch on the market is still about 3 days, the battery life of the Vivo Watch 2 has been directly increased to 7 days, all of which is due to the internal design of the Vivo Watch 2.
As a smartwatch that can make calls, Vivo Watch 2 uses the main control chip + communication chip architecture. The former drives the watch and the latter intelligently connects to the network.
The two do not interfere with each other but can assist each other, reducing the basic power consumption of the computing platform from the hardware level, so as to achieve the purpose of extending battery life.
In addition, unlike many other positioning mobile phone auxiliary hardware, Vivo Watch 2 can be used completely without the mobile phone. Listening to music, listening to audiobooks, and listening to talk shows can be done directly on the watch without importing programs from the mobile phone.
For users who like sports, Vivo Watch 2 has an exclusive sports playlist. For users who like to listen to books and talk shows, Vivo Watch 2 supports the Himalaya APP to listen online, and it can communicate with mobile phones and continue listening.
In terms of functionality, Vivo Watch 2 supports all-day heart rate and blood oxygen monitoring. The newly upgraded optical sensor supports continuous monitoring in the background and synchronizes the data to the mobile phone in real-time. All-day heart rate monitoring, the monitoring frequency can be adjusted through intelligent algorithms, and an alarm will be issued in time when the heart rate is abnormal.
Vivo Watch 2 has dozens of sports modes, uses a GoMore algorithm that is more in line with the Asian physique, real-time exercise guidance, scientific analysis can be provided after exercise, of course, direct connection to WeChat is also possible. The following are the detailed parameters of Vivo Watch 2:
Design 
The Vivo Watch 2 we received is the Original Force version, and the whole body is black and the color is very delicate. Different from the previous generation, Vivo Watch 2 cancels the numbers on the dial and uses a finer scale. This design that is deliberately distinguished from mechanical watches is very bold.
The dial size of the Vivo Watch 2 is 1.43 inches, 466*466 resolution, 326PPI, OLED material, and the overall display effect is delicate. It should be noted that the screen refresh rate of Vivo Watch 2 is 60Hz, and due to the compact body, the look and feel when used is much better than that of ordinary watches.
The advantage of using an OLED screen is that it saves more power. After all, the overall size of the watch is limited. How to maximize the efficiency of the limited battery capacity is one of the issues that manufacturers need to consider.
Due to its own material, when the dark background is displayed, the black part of the OLED screen is not powered, which provides the basis for the purpose of more power saving for Vivo Watch 2.
On the side of the watch are the only two physical buttons. Although all smartwatches now support touch, the shortcut function call-out button is still indispensable. The two physical buttons of Vivo Watch 2 are designed as shortcut function call-out buttons. The upper button is responsible for the application/Home function, and the lower button is responsible for various sports recording functions.
At the same time, the stainless steel dial has a strong sense of design, and the large-area drawing process has both gloss and wears resistance. This design combining metal and technology has a natural appeal to male users.
Compared with the previous generation, the ground of the Vivo Watch2 has subtle changes while retaining its characteristics. The composite material back shell and excellent design have both strength and beauty. The position of the charging port is changed from the single side of the previous generation to the two sides of the distribution, and the design is more suitable for daily actual needs.
The speaker openings are still on both sides of the bottom surface, with 3 openings on the left and right, which can be used to play mobile phone music. Of course, it is also possible to play music directly without a mobile phone. The fluorine rubber strap is slightly more elastic than the normal silicone strap, and it can ensure firmness during daily use without being too tight to cause discomfort.
The watch strap supports quick release, and the watch strap can be taken off by the buckles on both sides of the wave. The charging base is a common magnetic base, and the length of the bundled wire is about 80 cm, which is enough for daily use.
Call experience
The biggest feature of the Vivo Watch2 is the built-in micro main control chip and independent communication chip, which do not interfere with each other. The latter supports Vivo Watch 2 to make calls. This design is rare on smartwatches.
The call function of Vivo Watch2 uses an eSIM virtual card service. The advantage of eSIM is that it can save the cost of making physical cards, it is more convenient to change operators, and because there is no physical card, the SIM card slot of the mobile phone can be omitted, leaving more space for other configurations.
In high-end smartwatches, tablet computers, and other devices, eSIM has become more and more popular, and eSIM services have been implemented in China for some years, but they have not yet become mainstream. On Vivo Watch2, the eSIM service is placed in the eSIM and mobile network settings. After completing the relevant business in the business hall, you can use the services that have been activated, which is very convenient.
Different from other smartwatches, the phone function of the Vivo Watch2 is directly built into the function options. After clicking it, it is a complete 9-square dial. You can dial directly on Vivo Watch 2 when you use it, no need to take it again. Out of the phone. If you want to use the contact function, you need to synchronize the phone-Vivo Watch 2 on the health APP, and you can still call directly on the watch after synchronization.
The interface can display the number in real-time during a call. The left side of the hang-up key is the recording key, and the right side is the function key. Inside the function, keys are the call volume and number dial, at this time the # key comes out. It should be noted that when using Vivo Watch2, you can only choose hands-free for calls, and of course, the volume can be adjusted. Think about the way you call on the watch. Does it feel like Conan?
Functional experience
As a multi-functional smartwatch, Vivo Watch2 has many sports modes, including indoor running, outdoor running, trail running, rowing machine, outdoor cycling, pool swimming, mountain climbing, skipping rope, HIIT, and so on.
Press the button below to call out the function options, which is very convenient. In actual use, Vivo Watch2 can display exercise status in real-time, including mileage, heart rate before and after exercise, pace, calories burned, and so on. The watch display is more direct than the mobile phone, which also fits the original intention of the Vivo Watch 2 to get rid of the mobile phone.
More intimately, Vivo Watch2 can also check stride length, stride frequency, etc., and also prepares the recovery time after exercise to support the strenuous exercise and avoid injury caused by excessive exercise. Real-time monitoring of pressure and blood oxygen is another unique feature of Vivo Watch 2.
In the stress test, there are 3 levels of standards, low, medium, and high. There will be different exercise suggestions under different pressure situations. Users can arrange specific exercise plans according to the pressure situation.
It should be noted that the real-time blood oxygen monitoring function of Vivo Watch 2 needs to be tested manually, and the real-time blood oxygen data can be obtained by keeping relatively static for about 30 seconds during the test.
In the health APP on the mobile phone, the amount of daily exercise and heart rate, including week length and single day length, and the type of exercise include running, brisk walking, and so on.
It should be noted that, in addition to running and brisk walking, these functions will automatically count, other functions need to be manually turned on on the watch, such as elliptical exercise, swimming, etc.
In terms of heart rate monitoring, the APP will monitor and summarize the comparison of resting heart rate and exercise heart rate in real-time. The upper and lower limits are marked, allowing users to more intuitively understand the physical changes during exercise, so as to exercise healthy and avoid injuries caused by over-exercise.
In sleep monitoring, it takes 3 hours for Vivo Watch2 to generate detailed data. In sleep monitoring for more than 3 hours, you can view the proportion of deep sleep, sleep continuity, rapid eye movement, etc. in the health APP. , The monitoring system is more comprehensive, and you can intuitively check the quality of sleep.
Other functions
From the point of view of the watch function, Vivo Watch2 is designed to be completely separated from the mobile phone.
In addition to the eSIM card we mentioned earlier, you can use the eSIM card to make calls. Since the body comes with 2GB of memory, it is also possible to listen to songs directly on the Vivo Watch 2. The 2GB capacity can theoretically store 400 songs, which is quite large for the watch.
In addition to online use of NetEase Cloud Music, Himalaya, and other apps through the eSIM card, you can also choose to import music from your mobile phone, and the switch button in the lower right corner can switch the playback state at any time.
As a top-level smartwatch, the access card function of the Vivo Watch 2 is naturally indispensable, and of course, it needs to be adapted and adjusted on the phone.
Vivo Watch 2 realizes the access control card by adapting the mobile phone to transmit the signal to the smartwatch. Swiping the watch means swiping the access control card. This is also the current mainstream access control card implementation method.
In addition to supporting access cards, Vivo Watch 2 also supports transportation card all-in-one cards. When using, you can directly open the NFC card package function on the watch to select the corresponding card.
To realize the payment function of the watch, you need to open WeChat or Alipay and scan the QR code on the watch to call up the function during use.
We all know that the payment QR code is not unique, and the QR code will change after a certain period of time. This is of course for safety reasons, which also increases the difficulty of the smartwatch payment function. After all, it is only reserved. A photo is much less difficult than real-time updating.
Vivo Watch 2 can be connected with mobile phones, and the supported eSIM service comes in handy at this time. You can use the built-in eSIM service directly, and you can pay even if you don’t have a mobile phone.
Battery
Vivo Watch 2 is fully reconstructed from the chip, antenna, and power management. In the dual-terminal mode of the same number, Vivo Watch 2 has a battery life of 7 days, which is near twice the duration of many mainstream products in the current industry.
If you turn off the independent communication and use it in the Bluetooth scenario, you can still achieve 2 weeks of battery life, which is almost twice that of products of the same grade.
In our actual test, the continuous wearing time is 3 days, the test mode is to close the independent communication, the test items include daily exercise step count monitoring, running monitoring, 3 times a day blood oxygen test, sleep monitoring, mobile payment, and other functions, intensity Bigger than daily use.
After three days of testing, the power consumption is about 20%. It is not a problem to simply convert it for half a month. In order to test more intuitively, we tested the power of continuous music playback, let’s look at the results.
When we tested, we chose to close the independent communication, adjust the music volume to the maximum, and play music continuously. The test time is 30 minutes and the power consumption is 4%. A simple conversion can play music continuously for 12.5 hours.
Taking into account the actual usage scenarios of Vivo Watch 2, this battery life is already at the top level. Even if there is a daily demand for making calls and playing music, there is no need to worry about the power of the watch.
