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.

-
Typical Use: ~12 days.

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