HAYLOU Solar Lite 2 Smartwatch Review

The Haylou Solar Lite 2 is a major leap forward from its predecessor, shifting from a budget “basic” tracker to a more premium-feeling smartwatch. While the original Solar Lite was known for its simplicity and TFT screen, the Solar Lite 2 introduces a vibrant AMOLED display and Bluetooth calling while maintaining a sleek profile.

Having tested many watches in this price bracket the Solar lite 2 comes pack with more features than others at this pricepoint giving it a more favourable look of others and like many watches in this price tier they do not offer bluetooth calling where the Haylou Solar Lite 2 does which is a sought feature for those on a budget.

Haylou’s main pitch for the Solar Lite 2 is its 9.8mm ultra-thin design. It feels noticeably lighter and less bulky on the wrist than most competitors in this price bracket.

It features a high-gloss polished zinc alloy frame that gives it a more “executive” look compared to the matte plastic feel of the first generation.

It has been upgraded to 1ATM, meaning it handles splashes and rain much better, though it is still not a dedicated deep-diving watch.

The display  is the star of the show here. with a 1.43-inch AMOLED: Moving away from the 240×240 TFT of the original, the Solar Lite 2 features a 466×466 resolution with a 60Hz refresh rate. It is fast an smooth.

Colors are punchy, and the blacks are deep. It also supports Always-On Display (AOD), which was a major missing feature in previous “Lite” models.

Key Features & Performance

  • Bluetooth Calling: You can now make and receive calls directly from your wrist. The speaker is surprisingly clear for the price, though it struggles in windy outdoor environments.

  • Health Tracking: It utilizes a new self-developed algorithm for more accurate heart rate and $SpO_2$ monitoring. It also includes 24/7 stress tracking and female health management.

  • Fitness: With over 150 sports modes (up from 100), it covers almost any activity. It also syncs directly with Strava, which is a huge win for runners and cyclists who don’t want to be locked into the Haylou Fun app.

Battery Life

Despite the power-hungry AMOLED screen, Haylou has optimized the battery system:

  • Typical Use: ~12 days.

  • Heavy Use (AOD on, frequent calls): ~5–7 days.

  • Extended Battery Mode: Up to 30 days.

Is it worth it?

At roughly 40 euro, the Haylou Solar Lite 2 is one of the best value-for-money smartwatches on the market right now. It looks and feels like a watch twice its price. If you don’t need onboard GPS for running, this is a near-perfect daily driver.

Tech Review – DIKTOYOU Men’s Smartwatch

The smartwatch is today for some seen as an expensive companion device which is true to one extent but over the years they have come down in price and more brands to sell them alongside their smartphones, For example I have my original Moto 360 which was my first smartwatch and now I have the Apple Watch Series 7, Pixel Watch A Galaxy watch 4 and several other cheaper brands that all cost less than 100 euro which this one does but this one has features none of those sub 100 euro watches have and even more expensive watches and two stand out features is a speaker to take calls and a voice assistant and also has GPS tracking.

OK so the thing here is this is a generic watch we have seen before and the software to go with it but it is kept simple and everyone wants something different and that is life, it may have some restrictions as to what you can do overall however for the price it a seriously decent watch to get you started of you do not own a smartwatch and do not want a convoluted mess of submenus or set-up this is one watch you should look at and in fact we have done several similar styled watches here before which you can find in the search option.

We go through the set-up the app and all that good stuff in the video review below so you will see what this entails in comparison to other watches out there today, most people today opt for fitness trackers and these are cheaper etc but do not offer the full suite expected on a fully fledged smartwatch and this watch is kind of offering both here which is a good thing.

The watch is a solid build with an IP67 rating and comes with two straps it is not a cheap plastic watch which is often the case at this price point too and stellar battery life it does lots of fitness activities has a huge selection of predefined watchfaces and measures the most important health features and is pretty accurate after comparing to other smartwatches I own.

Check out the video below for more and see how the speaker sounds the calls sound and how it works in general as it is a better view of what this offers for the price. For me it is a great watch to get started and overall a great watch to use and the only place it lacks is on replying on the watch itself but as for the rest it is fine, notifications come through they are a simple line of text and not detailed like more expensive watches but still gives you control at a glance whether or not you need to pick up your phone and one thing for me with smartwatches is they do keep you off your phone and today that is probably a good thing as we spend to much time on them.
