Ultimate Guide On Solar Smartwatch In 2022

In this article, we will try to give you proper insights into solar smartwatches. Before digging into it, you may consider getting a brief introduction to solar smartwatches.

So, let’s get started!

What is a solar smartwatch?

A solar smartwatch is a type of smartwatch that operates by using light energy. Sophisticated features like prolonged battery performance and a superb GPS are included in an advanced quality solar smartwatch.

Every solar watch has a solar cell beneath the dial that transforms “light energy” into “electrical energy”.

You might not believe that the solar-powered watch actually was introduced in the 1970s with pretty basic features. But as technologies are advancing, as well as people’s adaptation with the technology is also increasing, solar watches manufacturers are coming with more advanced features.

Why is a solar smartwatch a better Choice?

If you are already a smartwatch user, then you might know the benefits that a smartwatch provides. And in every update, the futures and attributes are improving.

Yet, when using a smartwatch, the biggest concern is the battery. Even if you charge it throughout the whole night, your smartwatch’s battery still may die by mid-day as you are doing a lot of tasks on it.

But when you have a solar smartwatch, you won’t need to be worried about the battery as it keeps recharging when you are outside.

Apart from this, the regular watch’s battery may need to change after a few years, which decreases the quality of the watch, such as water resistance ability decreases and much more problems come with changing the battery. This problem can also be solved by solar smartwatches as their batteries last longer.

And not to mention, the design and shape variation of the solar smartwatches goes with almost every outfit, and obviously, they are largely eco-friendly.

How a solar smartwatch works

  • Solar smartwatches are recharged by using light energy but it is not necessary that you should put the watch only under the sunlight.
  • Any source of light is able to recharge your solar smartwatch.
  • The solar watch usually comes with a solar panel on the display, case, or even on the bezel.
  • Light energy is then converted in the solar panel into electric energy.
  • As soon as the watch gets the light, the solar panel converts it into energy.
  • However, there is also a power reserve on the solar watch that stores the extra energy that is not necessary immediately and to be able to use that energy later.
  • It means, even if you are not under any light source, your watch still may operate till the stored power is over.

How to charge a solar smartwatch

Direct sunlight is the best method to charge your smartwatch. But as mentioned earlier, you can also use other sources of light to recharge your watch.

However, 50,000 – 100,000 lux of strong sunlight for 2-3 hours is enough to recharge your solar watch completely. The required light and time may vary from brand to brand.

Other sources of light
If you don’t have enough sunlight, you can also use a fluorescent lamp’s light to recharge the battery.

  • If you keep your watch around 5 cm away from the 30W fluorescent lamp, it will provide around 100,000 lux.
  • If you keep it around 20 cm away from the 30W fluorescent lamp, it will provide around 3,000 lux.
  • In the office area, the light usually provides around 700 lux.

In this case, you may need a long period of time to recharge your watch completely. However, don’t forget that even if your watch isn’t under direct light, it continues to charge as you go outside or under any source of light.

Adverse Situations

There are also a few situations that are not suitable to charge your solar smartwatch. Those are as follow:

  • When the watch is hidden beneath the sleeve of your shirt.
  • When the watch is stored in an environment where the sunlight can’t reach for an extended period of time. For example the drawer of your cabinet or in your purse.

However, it is not enough to try to recharge your watch only by wearing it. Try to charge it intentionally on a regular basis under direct sunlight or other sources of light.

Tips for better charging

There are some tips that you can follow to ensure better charging of your solar smartwatch:

  • Place your watch near the window facing the sun directly.
  • When going outside, try to wear a sleeveless or folded sleeve shirt to get more sun exposure.
  • If you’re charging your solar smartwatch with a fluorescent lamp, keep it closer to the lamp (5 cm).

Battery longevity of solar smartwatch

The battery longevity of a solar smartwatch varies from brand to brand. However, as mentioned above, solar smartwatch battery longevity is usually more than other smart watches. Here are a list of different brand’s solar watch with the battery longevity:

  • Garmin Solar Instinct – Battery saver mode – 56 days
  • Garmin Solar Instinct – smartwatch mode – 24 days
  • Timex Men’s Expedition Scout Solar – 4 month reserve
  • Casio Men’s Pro Trek Smart – 5 month reusable battery
  • Haylou Solar Smart Watch – 30 days standby battery
