When Haylou headed into the smart wearable market several years ago, I thought it was just riding the trend. But what it has become now proves the extent of the company’s determination to provide added value to this sector, and this is what led to making its voice heard in the world of smartwatches, increasing demand and pushing the brand to produce more and more smartwatches that provide the best value for money, high quality, and Its most prominent product is the Haylou RS4 Plus, which is a crowd favorite and the most popular in its class.

Haylou, in this respect, almost never disappoints expectations: even in this case, therefore, we have a packaging that immediately shows the product on the front, hiding some main characteristics of the product on the back. Inside the sales package, then, reside the following accessories:

  • Haylou Solar Plus RT3
  • short USB-A cable with magnetic pins for charging
  • user manual
  • warranty certificate.

Design And Build Quality

It’s impossible to talk about the Haylou Solar Plus RT3 without mentioning how beautiful the design is. This model has a lot to envy. Unlike other competing devices, as soon as the Solar Plus RT3 is extracted from the box, the smartwatch presents itself to us in all its glory, with its zinc alloy body of great rigidity and its large 1.43-inch circular AMOLED panel and it looks elegant with its 2.5D curved glass. We can guarantee that the first impression will not be negative. The rounded face and simple curved body remind me of the Samsung Galaxy Watch Active 2, so the smartwatch is sure to be stylish in all situations, whether you want to use it for sporting activities or more events.

Truth be told, from a build point of view, after several days of use, I have yet to find any flaws in this component for its price, resulting in a glossy finish and no scratches just like day one. The same applies, of course, to the different sensors placed on the lower bezel, as well as to the two crown buttons on the right, the upper one is rotatable and clickable and through it, you can directly access the main menu and the other one lacks the same rotation and clicking it switches to the sports modes. To make calls, just below the button, you’ll find the microphone, and the addition of holes in the left part, which is the built-in speaker.

The strap is one of the important things to complete the overall look of the watch, which is why it is made of silicone, it is lightweight and comfortable on your wrist for long-term use and does not feel on the wrist in the least. And because it’s removable, you can use any 22mm strap in metal or leather.

Display Screen

On the other hand, Haylou has invested heavily in the most important aspect of the smartwatch which is the amazing display quality, I am happy to say that I was completely impressed with its display on the Haylou Solar Plus RT3. When I first turned on the watch, I was immediately greeted with vividly saturated colors and deep shades of black that blend almost seamlessly with the bezel. When you also factor in how narrow the bezels around the screen are, the watch face appears less rounded. I was really shocked because this is a display offered on an under $50 smartwatch.

By far, the most notable part of the Solar Plus RT3 is the large, bright, customizable 1.43-inch 466*466-pixel AMOLED display with an always-on mode that lets you view the current time, how many steps you’ve taken while walking, the battery level, message notifications you’ve received on your smartphone and various other information will be available without you necessarily needing to unlock the watch, making It keeps you aware of every important moment in your life around the watch. One problem is that it takes the term Always-on very literally and remains active even after you remove the watch from your wrist, consuming more battery life. There’s a library of watch faces, though you’ll need to install most of the new faces through the Haylou Fun app on your smartphone.

That’s why a sharp, vivid screen is central to the success of a smartwatch product, and the watch face stands out, and this is something Apple does very well in its watches. Also worth noting is the peak brightness that is capable of rendering content on the screen even in direct sunlight. Texts and numbers are crystal clear for reading. Therefore, there is no problem in displaying various contents on the screen. The contrast and sharpness offered by 60Hz elevate this panel on par with most popular competitors.

Solar Plus RT3 Watch faces

If you’re tired of the system’s default dial wallpaper, Haylou has made concerted efforts to design a slew of versatile watch faces with customization support so you can choose from over 100 watch faces with different themes from the app. Custom watch faces are also available, letting you choose one that perfectly matches your mood and outfit. You can easily switch between them in many ways, by long-pressing on the home screen or via the Haylou Fun app, or simply using the rotating top button. It has included a variety of retro, analog, 3D, and digital faces, or you can even use your own as a watch face wallpaper or any background and have the ability to customize. And with the wrist feature to wake the screen and always-on mode, that would be great.

Like the previous smartwatches for Haylou, the Haylou Solar Plus has an IP68 Waterproof certification, which it means can only handle sweat and splashes of water, although the watch is not approved for swimming but is good for wearing for activities, so, I do not recommend swimming or exposing it to hot water or saltwater to avoid any harm Long or short term and with the presence of a speaker and a microphone, avoiding it will be good, however, if it’s exposed to water in any way, I prefer to dry the watch after immersing it in water and before operating it so that it stays with you for as long as possible.

How To Use Haylou Solar Plus RT3

In my testing, the screen responded to scrolling and taps without the slightest delay or uncertainty, as you can navigate within the different menus thanks to different gestures on the screen with which to perform the following actions:

  • Swiping from the top reveals the Control Center, where we find the option to activate the flashlight, do not disturb mode, screen timer, alarm clock, rotate the wrist, find my phone, adjust brightness and general settings in addition to the power saving mode;
  • swipe up: access notifications, which can only be viewed on the screen but are impossible to interact with in any way;
  • Swipe left or right: With this gesture, you can access some summary pages that display activity status, heart rate, blood pressure, blood oxygen level, and sleep. Going to the right, you will obviously go around in a loop and get to the main quarter, which can be changed at any time.

The main menu can be accessed by pressing the top button, you will find Watch, Activity, Heart Rate, Sleep, Blood Oxygen, Sports, Exercise Log, Pressure, Temperature, Breathing, Notifications, Time, Music, Calendar, Calculator, Stopwatch, Timer, Alarm and Settings, and more. Also, it supports 3 viewing modes (cellular, waterfall, and list views) You can change between them from the settings.

Hardware & Connectivity

Under the body, we find a sector of hardware in line with this price range, so the Solar Plus RT3 is equipped with Bluetooth 5.3 allows ultra-strong wireless connection with the smartphone quickly and accurately with the possibility of making calls directly from your watch and without delay. Turning to the application developed by the brand, in fact, we see how the information detected by the smartwatch is transmitted to the application fairly quickly. Also, it’s able to manage all operations in the best possible way. Among the latter we have: measured heart rate, blood oxygen, stress, and temperature, albeit with an accuracy that is acceptable for its price. Then getting up with the wrist movement is excellent, fast, and fairly accurate. Finally, the absence of a built-in GPS and NFC module will force you to rely on your smartphone.

Health & Fitness Functions

The Haylou Solar Plus RT3 is competitive in all aspects that a smartwatch mainly needs. Taking a look at the sports activities, it is clear that the company wanted to provide everything necessary to facilitate the end user.

With more than 105 types of exercise, the Solar Plus RT3 is prepared for practically any type of exercise, from walking to cycling, through all winter sports and those involving the use of the ball. By scrolling through this list, in fact, it is possible to explore the different options, finding in fact countless different activities. But the main factors, after all, are always the same and are suggested as follows: outdoor running, indoor running, outdoor walking, indoor walking, outdoor cycling, indoor cycling, climbing Mountain, hiking, cross-country running, elliptical running, rowing machine, free workout. By clicking on more sports, you can access another list of different activities including curling, table tennis, karate, archery, frisbee, darts, barre, belly dancing, and many others. She wasn’t kidding when Haylou said “you get access to your personal trainer at your fingertips”

In addition to physical activity, the Haylou Solar Plus is equipped with various sensors to detect heart rate, and track sleep, stress, SpO2 level, and breathing rate. And Haylou did not disappoint me in tracking the heart rate as it was very accurate and it works 24 hours a day, you are connected all the time regarding the heartbeat and when there is a spike in these readings, you will be alerted immediately, and all of this applies to SpO2 too. As for step tracking, while it’s pretty generous with step counting, it’s still surprisingly accurate for a watch that costs just $50. As expected from Haylou!

There is also an option to test your mood, although I am not sure about its sufficiency. However, I was quite satisfied with the results obtained from sleep monitoring by detecting the time you fall asleep and the time you wake up. So I think Haylou has done a great job in this regard, and also showed us many other data related to deep sleep and light sleep.

In short, as a smartwatch to track fitness, health, and sports, we can say that Haylou Solar Plus RT3 does a good enough job for us. Also, remember that monitoring data and results are for reference only and not for diagnosis or treatment.

Haylou Fun App For Solar Plus RT3

On the phone side, the work Haylou has done on the Haylou Fun app has been painstaking, though it reminds us of other Chinese companies and how they designed their fitness apps. If you have used an Amazfit or Huawei watch, this app will look very similar.
This can be easily found on the Apple Store and Play Store and is absolutely free. It is therefore simply necessary to open it, add the smartwatch and wait for the entire configuration phase.

How To Pair The Haylou Solar Plus

Connecting the smartwatch to your phone is very simple:

  • Turn on the Bluetooth of the watch and mobile phone.
  • Click Add device in the APP settings to connect the watch to the APP.

How Haylou Fun App Works

Once all operations are completed, the various information detected by the wearable device will also be quickly reported on the APP. As in previous models, the user interface is easy to navigate, which at least from a graphic point of view is coherent and intuitive. In fact, from the main screen, we can instantly get an overview of our activities, as well as take a look at our heart rate, sleep monitoring, pressure, and body weight.
Set various heart rate monitoring options, enable notifications from different apps, set a reminder, and much more. But not only that, because in addition to all the various information on the smartwatch itself, it is possible to display more data within each individual area on the main page of the application. By clicking on the heart rate square, for example, we immediately see the full graph for the day, with all the different measurements, as well as data on the average frequency, and maximum and minimum beats.

Bluetooth Calling On Haylou Solar Plus RT3

Unlike other “smartwatches” that only notify you when a call arrives, One of the most attention-grabbing highlights of Haylou Solar Plus RT3 is the ability you can answer your smartphone calls directly from the smartwatch. Just sync them via Bluetooth 5.3 and, as soon as you receive a call, click on the button that will appear on your watch’s screen to answer it.
it’s equipped with an integrated microphone and a speaker, with the former serving up surprisingly clear sound that can be heard over general din (such as road noise), making it usable, As for the microphone, it’s mainly used for on-wrist calls or, if you’re paired to a smartphone. So it not only displays an incoming call but can also receive and dial calls made via Bluetooth directly from the watch with good sound from the speakers and a mic, and of course, this is done with your smartphone, So you don’t have to take out the phone of your pocket every time you want to make or answer a simple call.

Haylou Solar Plus RT3 Battery Life & Charging Time

The battery performance of the RT3 varies depending on how you use it and what you use it for, as some features will drain the battery more. And because it has a capacity of 220 mAh battery allows a standby time of up to 20 days. For continuous use, the brand advertises 7 days with 24/7 heart monitor use. The watch charges in about two hours.

However, this is on paper but in reality, it may differ slightly since when fully charged, the watch barely managed to reach the end of the third day. This difference in endurance is mostly due to the always-on feature, which may have affected performance. With its battery saver mode, it’s possible to increase battery life by 15 days by turning off Bluetooth connectivity and features like heart rate monitoring, leaving you with basics like steps and time. Despite all this, I can say that the battery of the Haylou Solar Plus is impressive.
