Haylou RS3 : test / review / opinion

Haylou RS3 : test / review / opinion

Category: Smartwatch

I started testing smartwatches about 1 year ago and 12 months ago I tested 16. I mainly tested Chinese brands and thought I had the main brands (Amazfit, Mi Watch, Kospet, Mibro, Zeblaze, ...) but the Chinese industry does not seem to have any limits and I completely missed out on the Haylou brand. The Haylou brand is a Chinese brand which has existed since 2015 and which has benefited from the financial support of Xiaomi, Haylou is also part of the Xiaomi ecosystem which brings a number of commercial benefits. Xiaomi has really spread its web all over China and in general they make good choices, so I'm curious to see how Haylou has managed to translate this medium into a product that manages to differentiate itself from the rest. The Haylou RS3 is a watch that rises above the Chinese entry level. I have tested many watches for less than € 30, the Haylou RS3 will be positioned a little over € 40. It's not a big difference but it has an Amoled screen and a GPS chip, these are quite rare features in this price zone. Apart from Xiaomi, I haven't seen a lot of such products in this price range.[b][b][b][b]

How are my tests different from others on the web?

- I usually buy the devices with my own money, so price is just as important as you are!
- I keep the devices for at least a few weeks (sometimes more) to see what they are worth in real conditions.
- I answer (when possible) your questions to help you decide before you buy
- no one pays me to do these reviews, so I'm completely neutral and independent...
- My pages are not filled with ads

Timeline

07/01/2021 Haylou RS3 test begins[b]

Waarom deze smartwatch?

What motivated me to test this watch is its price, its screen and the fact that it is equipped with a gps chip. There are many watches with a gps chip and an amoled screen but in this price range only Xiaomi manages to market such watches. The Haylou RS3 is also distinguished by its circular design where many manufacturers have copied each other by offering a rectangular model.[b]

Structure of my tests

I test products according to a pre-established structure (see below) to provide you with maximum information. Unfortunately, this takes a lot of time. Unlike some sites where products are tested on a single day, I use the products I test for a minimum of a few weeks and sometimes even a few months. If the test is not complete at the time of your visit, I invite you to come back later or ask your question in the comment section below.

Unpacking

The packaging of a product often gives an indication of the positioning of the product and the Haylou RS3 is not positioned at the entry level or in the premium range. The packaging is neat without having a wow effect, but we are far from the simplistic packaging of brands like Kospet for example. The box contains the watch, a magnetic charger via USB and a manual. [b]

First configuration

To configure the Haylou RS3, you must download the Haylou Fun application. I had not yet had the opportunity to test this application and I will come back to it later in this article. It is not possible to use the watch without going through the configuration via the application, I find that quite a shame. Configuration can be done by automatic detection or QR code. I first tried to set up the watch with my Samsung Galaxy S20 but couldn't because the app asks for permission to run in the background and this option on my Samsung was still greyed out. So I fell back on a Poco X3 Pro and there, on the other hand, the configuration worked the first time. The configuration (when it works) is quite easy but I was a little surprised by the number of permissions requested by the application, it only gave me a very positive feeling but I would see in use if it poses any problem. So there is nothing to worry about at this stage, if I notice anything abnormal I would point it out in my article. [b]

Finish

I am not what we call a "fashion victim" and I do not place a lot of importance on the appearance of products, I prefer a product that works well above all else. On the other hand, like everyone else, I have a subjective first impression and this impression was really positive for the Haylou RS3. I think this watch is really beautiful, the proportions are really ideal because the watch is neither too small nor too big. At this price point, the watch is mainly made of plastic but the whole holds the road quite well. I have tested many watches and I was used to the rectangular design like the Amazfit GTS but in the end I prefer this circular model, I find it more elegant. It is obviously very subjective but I give you my feelings when I had the watch in hand for the first time. [b]

Connectivity

The Haylou RS3 synchronizes in Bluetooth with your smartphone and has a GPS chipset which makes it completely autonomous for your trips outside.[b]

Battery range

The Haylou site announces that the Haylou RS3 has an autonomy of 21 days. When I saw this, I thought it was probably pretty ambitious but in reality the battery life is very good. I lasted 17 days with the first charge and depending on the intensity of use, I obtain an autonomy between 10 and 20 days. I am positively surprised because it is mainly connected bracelets that offer such autonomy.[b]

Screen quality

The Haylou RS3 is equipped with an Amoled screen, in this price range it is very rare. The Haylou RS3's amoled screen offers almost infinite contrast and excellent readability (even when looking at the screen from the side). With the brightness at maximum, the face of the watch is readable in direct sunlight, but sometimes you have to change the orientation of the wrist a little because the surface of the screen behaves like a mirror. [b][b] The screen resolution reaches 390x390 pixels and with a screen size of 1.2 inches, the pixel density is very important for a watch. The details are therefore very fine and even the small print is easily readable. [b][b] You can change the screen interface by leaving your finger on the screen for a few seconds. This is a nice feature except that if you cross your arms and your skin touches the screen, the watch will offer to change the screen.[b]

Features

The Haylou RS3 is a watch offering the basic functionality usually found on watches in this price range. The top screen lets you configure the world, activate night mode, manage the screen brightness and find your phone. The left / right screens are widgets providing access to the most common features of the watch and the lower screen provides access to the full menu. The button at the top left allows you to go back and the one at the bottom gives access to sport mode. The Haylou RS3 has a very simple and very clear interface, it does not play the abundance card like other brands.[b]

Measurements

Heart rate [b] The main flaw of entry-level watches is the reliability of heart rate measurement. I tested the Haylou RS3 with several types of activities (outdoor cycling, outdoor walking, indoor cycling) and got the results below comparing them with my Polar H10 belt. [b][b] Outdoor bike - average / max heart rate Haylou: 113/131 [b] Outdoor bike - average / max heart rate Polar: 159/183 [b][b] Indoor bike - average / max heart rate Haylou: 113/126 [b] Indoor bike - average / max heart rate Polar: 115/149 [b][b] Heart rate measurements are therefore not not very reliable, they are better in a static position (indoor bike) than in a position where the watch will move. [b][b] GPS position [b] The Haylou RS3 has its own GPS chipset, so it is completely autonomous for positioning. The connection to the GPS network is not always very fast but rather than waiting for the connection to be made, it is best to start the exercise. Positioning on a map looks pretty good, for example I did a test walking around a body of water where there is no road the map can hang onto and as you can see , my route is quite faithful because I stopped several times at the water's edge to take pictures and we can see my round trips.
On the other hand, the distance calculation is less precise because on a bike trip of 11km, the watch indicates a distance of 10 km. The difference may be due to the slow GPS connection, the watch may have missed the first mile. On the other hand, the layout on the map seems correct. [b][b] Sleep measurement [b] Like most watches, the Haylou is trapped by a position that is too static at night. If you watch TV without fidgeting too much, the watch will think you are asleep. I never gave much credibility to this kind of measurement but most watches tell me that I have very little deep sleep where the Haylou indicates that I have a very high proportion of deep sleep. I do not know if we can trust this kind of measure. [b][b] Number of steps [b] To measure the number of steps, I always walk on regular ground with a normal gait so that I can test all watches equally. The calculation of the number of steps on the Haylou RS3 seems very reliable because I did not have a deviation of more than 1 or 2 steps in my measurements. [b][b] Oxygen in the blood [b] I don't have a device to measure the level of oxygen in the blood, I know therefore not if the result obtained on the watch is reliable. I always got values between 96 and 100%[b]

App

To be able to use the Haylou RS3, you must download the Haylou Fun app from the Play Store or App Store. This app is free. As a whole this application is quite easy to use, the main screen gives you access to the most common measurements (heart rate, sleep, ...) but if you need something else you will have to search a little. If you want for example to change the face of the watch, you must click on the icon indicating the status of the connection of the watch, if you want to list the exercises recorded by the watch you must click on the three small dots at the top on the right of the screen with the map, ... in short, it's not always intuitive but once you know where to click, everything goes very well. [b][b] There are some translation errors as is often the case with Chinese applications, the customization possibilities are quite limited, you can change the dial but the list is rather short and the dials are not all very interesting.[b]

Compatibility

The Haylou RS3 is compatible with all phones capable of running the Haylou Fun app[b]

Operating system

The Haylou RS3 operating system is a proprietary system, which means you cannot change anything apart from the customization options. The interface is very well designed, it does not necessarily follow the codes established on other brands but we quickly find our benchmarks. The screens to the left and right of the home screen form a loop with a small graphical interface representing the main features of the watch. The top screen allows you to change the brightness, switch to night mode, find your phone or change settings. The screen at the bottom of the main screen gives access to all the functions of the watch. The operating system is very responsive, I didn't experience a slowdown. I also did not encounter any inconsistency in the menus or major translation errors like on other Chinese watches.[b][b]

Compare Haylou RS3 with the others

I assigned a score of 1 to 10 for each test that determines the strengths and weaknesses of a product. I am using 0 for criteria that have not (yet) been tested. A score of 1 to 3 indicates poor performance (and yes, it does), a score of 4 to 6 indicates average performance, a score of 7 to 8 indicates good performance, and a score of 9 and 10 indicates exceptional performance. .
The score is calculated based on my measurements and when there are no measurements, it is a subjective opinion based on my experience.

The scores are not static, they change over time because the performance of new products changes and this must be taken into account.

Test / Review conclusion

I did not know the Haylou brand before testing this watch, I am very happy to have been able to test it because even if everything is not perfect, this watch still has some interesting things to offer. The Haylou RS3 is sleek, it's neither too big nor too small, and although it's largely constructed from plastic, the level of finish is really good for a watch of this price point. Beyond the purely aesthetic aspect, the screen of the Haylou RS3 is a real success. The screen offers very good readability and excellent contrast because Haylou has chosen an amoled screen where most brands use an LCD screen in this price range. [b][b] The operating system is a proprietary system only available on watches of this brand but the same goes for all watches in this price range. Haylou's operating system is very easy to use, it works flawlessly. I regret that it does not offer more possibility of customization because that would have made it possible to better exploit the quality of the screen. [b][b] The battery life is one of the strengths of this watch, I obtained an autonomy of ten days in regular use (2 to 3 hours of sport) and almost 20 days in non-intensive use. I rarely test watches that are capable of exceeding the two-week mark, this territory is more that of bracelets [b][b] The Haylou RS3 is not a watch designed for athletes looking to improve their performance because heart rate measurements are not always reliable and the gps takes a long time to record the position. This watch should no longer be seen for recreational sports use.
