Best Smartwatches With Long Battery Life Buying Guide Battery Life

The relationship between battery life and smartwatches is pretty simple: the more features they have, the more energy they will consume — lowering their battery life. Smartwatches With Long Battery Life.

Average Smartwatch Battery Life

Typical smartwatch batteries don’t last more than a day or two. Even watches by Apple and Samsung provide average battery life.

But if you do your research, you can find models that optimize power consumption through internal software.

These last longer than average watches, so you don’t have to worry about frequent charging.

Battery Types

Three types of batteries are most commonly used: silver oxide, alkaline, or lithium.

Lithium button cells are larger than the other two batteries and are of the 3-volt cell type. Silver oxide and alkaline cells are smaller, around 1.5 volts.

Silver Oxide

The silver oxide cell is a successor of the mercury battery and is much superior. Although their construction is quite similar to mercury batteries, they have a higher capacity: around 1.62 volts.

Lithium

Lithium cells are shaped like coins and are often referred to as “coin cells.” They are rated higher than other watch battery types, with the Lithium-Manganese Dioxide being rated at 3.0 volts.

Smartwatch Battery Quality

Smartwatches With Long Battery Life. Don’t expect any smartwatch battery to last you more than a few days, no matter how high the quality. Their batteries are not so different from regular smartphone batteries and offer roughly the same life.

Some watch brands that claim to produce the smartwatch with the “longest battery life” will often add a damning disclaimer.

This disclaimer would require users to disable battery-consuming features such as heart rate monitoring, sleep tracking, and GPS tracking to ensure the advertised longevity.

Solar Powered Options

A solar-powered smartwatch runs on a solar cell, absorbing sunlight or artificial light to charge the solar panel behind the crystal.

To power the watch, this solar energy is converted into electrical energy. During the night or overcast weather, the device uses stored energy from its rechargeable cell to power up.

Watch Face & Design

Although a watch is meant to tell time, its style is what differentiates each model. The dial, hands, bezels, and crown are components that differ from watch to watch.

Watch dials can be found in bland, textured, or slightly tweaked variants. Similarly, standard sub-dial options are chronograph, moon-phase, and panda designs, among many others.

The good thing about smartwatches is that you can choose from various analog or digital dial faces.

Features

There’s a smartwatch for every purpose. Whether it’s tracking a run, monitoring your sleep, or your stress, you can find a cocktail of features with each model.

Let’s take a look at some of the features commonly found these days:

Heart Rate Monitor

Smartwatches with heart rate monitoring technology allow you to regularly check your heart rate, track your data, and be notified of abnormal spikes in your heart’s performance.

They’re great for managing stress and tracking your heart health.

Activity Tracking

Smartwatches commonly come with activity trackers. These let users stay on top of their fitness game and gain insights into their daily activity statistics.

This data can help you achieve your fitness goals better and plan your exercise for improved gains.

Sleep Tracking

A wide variety of smartwatches feature sleep trackers. They can track your sleep duration, your sleep quality, and the phases of your sleep.

GPS Mode

GPS tracking is essential if you’re used to venturing out into uncharted territories. While they consume more battery, they can be a game-changer for training and tracking distances.

Find a watch with this mode to know precisely where you are and how to find your way.

Our Verdict

Smartwatches With Long Battery Life. In our pursuit of the longest battery life smartwatch, we found the Garmin Fenix 6 Pro to be a true masterpiece, but only if you have the budget for it.

For lower budgets, we would recommend the Garmin Vivoactive 3. If you want a compromise between both and an overall best fit, the Fitbit Blaze is our favorite.
