What is a Smartwatch?

A smartwatch is a watch that comes with extra connectivity and functionality on top of the features provided by ordinary watches. These watches include a computer system that executes normal functionality as expected and has extra bells and whistles.

Smartwatches are available in a range of designs and functionalities. Most of them share the same functionality and have the same features. Here are some common features found in smartwatches:

  • Displaying time to the user
  • Keeping track of time
  • Setting an alarm
  • GPS tracking

Some common design features include:

  • Have a watch face or screen
  • Worn on the wrist
  • Use buttons, a touchscreen, or a dial to provide deliberate input

Why Do Most Smartwatches Lack Longer Battery Life?

Several factors have combined to make smartwatch battery life difficult, the main one being ergonomics. On the technical side, nothing is stopping these tech giants from slapping huge batteries on your wrist. But these smartwatches could easily become uncomfortable or heavy for everyday use.

Wearable engineers are striving to create a balance between battery life and other factors like comfort. One of the main reasons for low battery life is software support. Although you’d want a smartwatch that packs several apps, this demands a power-hungry processor, not to mention a slick interface and a quality display.

Fortunately, some smartwatch brands have come up with clever tricks to minimize power consumption. Some devices with an always-on screen are now scaling back refresh rates and brightness once you lower your wrist. Fortunately, there are some smartwatches that come with long battery life without compromising their functionalities.

Smartwatch with Long Battery Life Buying Guide

Finding the best smartwatches with long battery life can be overwhelming. There are tons of options out there, so it’s important to choose one that suits your needs. Here are some factors to consider if you want a long battery life smartwatch.


Before adding a smartwatch to the cart, ensure the device is compatible with your computer or smartphone. Some smartwatches only sync with Apple’s iOS while others Android and most do not sync with Windows.


If you’re a swimmer or love working out in humid areas, it’s advisable to look for a water-resistant smartwatch. Make sure you check the manufacturer’s specs to confirm the degree of resistance that the smartwatch offers.

Reliable GPS

One of the main features that you should consider when looking for a smartwatch is a reliable GPS. If you like cycling, running, or jogging, then a GPS is an excellent addition since you’ll be able to track your exercise when you’re outside. Other smartwatches can be connected to a GPS on your smartphone to help you monitor your progress after working out. If possible, look for a smartwatch that has a built-in GPS.


Smartwatches come with either an AMOLED display or a colorful LCD screen that facilitates clear viewing with rich images and bright colors. There is a known fact that colored displays consume a lot of power.


One of the most important factors to consider when purchasing a smartwatch with long battery life is its design. Looks are crucial and bring a positive change in your personality. If you want to get the best out of your smartwatch, look for one that fits in almost every outfit.

Touch or Buttons

Your preference and convenience will determine what you choose between the two options. If you love old-school designs, devices with physical buttons will suit you. However, touchscreens are preferred by most people.


Smartwatches are meant to be worn for a more extended period. Therefore, always choose one that promises extreme comfort even for a long time. Also, look for a watch that has a lightweight design and barely feels on your wrist.


Ensure you pick a smartwatch that falls with your budget. Pick one that has the features you need and provides the best value for its price. Don’t spend extra dollars on features you don’t require.
