How To Choose the Right Smartwatch with long battery life For Power Users?

If you are a power user and you want to choose the right smartwatch for you, this section is for you. In this section, I’ll outline the things which you should consider when you are buying a smartwatch for a power user.

Battery Capacity

If you are a power user then the first thing you should consider in a smartwatch is its battery capacity. If a smartwatch has a bigger battery, it means that you will get a longer battery life.

So, when you are looking for a smartwatch, make sure that it has good battery life. In my opinion, an ideal smartwatch for power users will offer at least 2 days of battery life.

Also, if it has features such as quick charging it would be awesome but it’s also a fact that quick charging is not available on most smartwatches.

Features

The second thing you should consider when choosing a smartwatch for a power user is its features. If you need a smartwatch for tracking your workouts, make sure that it offers accurate workout tracking and has dedicated workout modes for your favorite workouts. Similarly, if you want to use it for sleep tracking, make sure that its sleep tracking is accurate.

It’s also a fact that having more features means that they will drain more battery so you will have to manage them efficiently to get better battery life.

Display Type

The Display of a smartwatch also plays an important role in determining the battery life of a smartwatch. Most smartwatches these days come with OLED & AMOLED Panels which offer crisp picture quality and they are also more power efficient than LCD displays. Similarly, on Apple Watches you will find Apple’s very own Retina Display which has better resolution than AMOLED panels but it’s not as power efficient as AMOLED panels.

Usage Pattern

Usage Pattern is another very important thing that you should consider when you are buying a smartwatch for a power user. For example, if you have an active lifestyle and you want to use the GPS all the time, then the battery of the smartwatch will drain faster.

So, you will need a smartwatch with bigger battery life and eventually, you will have to go for big-size smartwatches because they come with bigger batteries.

On the other hand, If you have a moderately active lifestyle and you won’t need to use GPS all the time, you can get good battery life with small smartwatches. All you will have to do is to manage GPS usage and other features and you will get good battery life. 

Compatibility

Last, but not least, you will also have to make sure that the smartwatch you choose is compatible with your smartphone.

For example, Wear OS Smartwatches are only compatible with Android smartphones and Apple Watches are only compatible with iPhones. So, make sure that the smartwatch you choose is compatible with your phone.

List OF 14 Best Smartwatches With The Longest Battery Life For Power Users

In 2023, we have many smartwatches available which claim to offer the best battery life but not all of them can deliver on that promise. So, after extensive research and review of top-performing smartwatches, I’ve handpicked the best 14 smartwatches that offer the longest battery life.

1. Garmin Enduro 2 – Best Overall Smartwatch for Power Users

Garmin Enduro 2 is arguably one of the best smartwatches with the longest battery life in 2023. This smartwatch is designed for Power users and it comes with exceptional battery life.

In Garmin Enduro 2, you get a big battery that offers up to 110 hours of battery life with GPS. If you stay outdoors in the sunlight, you can get up to 150 hours of battery life with GPS which is exceptional. Similarly, if you don’t use GPS all day and only use it for tracking workouts, you can get around 20 to 30 days of battery life on a single charge.

Another highlight of the Enduro is that it’s capable of recharging itself using Solar Energy. So, as long as it stays in sunlight, it will keep recharging the battery.

As Garmin Enduro 2 is an adventure smartwatch, it comes with a rugged body that features a titanium body and Power Sapphire glass. In terms of features, you get features such as SPO2, Body battery, respiration rate, stress tracker, heart-rate monitor, music storage, and tons of sensors.

Overall, Garmin Enduro 2 is a solid smartwatch with exceptional battery life and it’s arguably one of the best options for power users.

2. Samsung Galaxy Watch 5 Pro – Best Android Smartwatch for Power Users

Samsung Galaxy Watch 5 Pro is a top-of-the-line Galaxy Watch and it offers the best battery life among all the smartwatches offered by the company.

As it’s a Pro smartwatch, it comes with a bigger 590 mAh battery which easily offers up to 80 hours of battery life on a single charge. In my case, I use the Galaxy Watch 5 for tracking my running and cycling sessions and I got an average of around 3 days of battery life before I need to charge it again. On top of that, the watch is capable of fast wireless charging and it takes around 90 minutes to fully recharge the smartwatch.

In terms of features, Galaxy Watch 5 Pro offers tons of advanced features that include ECG, SPO2, Fall detection, automatic workout detection, advanced sleep tracking, stress tracking, and other useful features.

Also, the Galaxy Watch 5 pro is pretty durable with its titanium body and sapphire crystal glass. Overall, if you are looking for a high-end Android smartwatch with exceptional battery life, you can’t go wrong with Samsung Galaxy Watch 5 Pro.

3. Apple Watch Ultra – Best Apple Watch for Power Users

Apple Watch Ultra is a top-of-the-line Apple Watch and it’s the ideal option for Power Users who own an iPhone.

In the Apple Watch Ultra, you get 36 hours of battery life with normal use and if you use the GPS, you will get around 18 hours of battery life. The overall battery life of the Apple Watch Ultra is not as good as Garmin Enduro 2 or Galaxy Watch 5 Pro but it’s respectable as compared to other Apple Watches.

The good thing about Apple Watch Ultra is that it supports fast charging and it will take around 1.5 hours to completely recharge the battery.

In terms of specs, you get all the premium features such as ECG, Satellite connectivity, Fall detection, SPO2, sleep tracking, advanced temperature sensing capabilities, LTE connectivity, and automatic workout detection.

When it comes to built quality, Apple Watch Ultra is as good as any other top-tier smartwatch out there. It comes with a titanium body and flat sapphire crystal glass which makes the watch very durable.

So, if you are a Power user with an iPhone, you should consider the Apple Watch Ultra because it’s the best option for you.

4. Withings Scanwatch Horizon – Best Hybrid Smartwatch for Power Users

Withings Scanwatch Horizon is one of the best Hybrid Smartwatches that comes with exceptional battery life. 

While the Withings Scanwatch Horizon offers 30 days of exceptional battery life, there’s a caveat to it that you should consider. The Scanwatch Horizon doesn’t come with built-in GPS which explains why this hybrid smartwatch comes with such good battery life. 

Technically, you can still use GPS with it by connecting the smartwatch to your smartphone but I don’t think it’ll be a good option for many runners. So, if you are an avid runner like me, you will not get the most out of this smartwatch. However, if you are looking for a hybrid smartwatch with good battery life, you can consider this smartwatch.

Moving on to battery life, the company offers 30 days of battery life but in my tests, I was able to get around 20 days of battery life which is not bad.

In Withings Scanwatch Horizon, you get a suite of advanced features such as ECG, SPO2, advanced sleep tracking, workout tracking, and activity tracking.

Also, the built quality of the Withings Scanwatch Horizon is pretty good. You get the stainless steel body and sapphire glass on top which makes the watch very durable.

So, If you are looking for a Hybrid smartwatch with exceptional battery life for power users, you can’t go wrong with Withings Scanwatch Horizon.

5. Garmin Epix (Gen 2)

Garmin Epix (Gen 2) is another very high-quality smartwatch by Garmin that can be a good option for Power Users.

The battery life of Garmin Epix (Gen 2) is around 42 hours with GPS. If you don’t use GPS all the time, then you can easily get around 50 to 60 hours of battery life on a single charge. The watch also comes with battery saver mode and when enabled, the Epix 2 will offer up to 21 days of battery life.

In terms of features, the Epix (Gen 2) comes with heart-rate monitoring, SPO2, hydration tracking, stress monitoring, sleep tracking, workout detection, smart notifications, and many other promising features,

The built quality of the Garmin Epix (Gen 2) is pretty good. The skeleton of the body is made of Polymer featuring a stainless steel bezel on top and a steel cover on the rear side. The company has Corning Gorilla Glass on top to protect the display of the watch.

Overall, Garmin Epix (Gen 2) is a solid smartwatch and if you are looking for a multi-purpose smartwatch for a power user, you should consider Garmin Epix (Gen 2). However, if you want a more durable and athletes-focused smartwatch, you should go with Garmin Enduro 2.

6. Fitbit Versa 4

Fitbit Versa 4 is another very good smartwatch for Power Users. Although Versa 4 is not as good as premium options such as Apple Watch Ultra, Garmin Enduro 2, or Galaxy Watch 5 Pro, it offers good battery life in its category. 

The company claims that Versa 4 can last up to 6 days on a single charge and this estimate is without the GPS. If you keep the GPS on all the time, you will get around 12 hours of battery on a single charge which is not good. However, If you use the GPS only for workouts and keep it off when you are not doing workouts, you can easily get around a full day of battery life on a single charge. 

Versa 4 also comes with many good features such as heart-rate monitoring, workout tracking, sleep tracking, stress monitoring, step counter, and menstrual cycle tracking for women. 

The built quality of the Versa 4 is also pretty good. It comes with an aluminum body which allows it to handle bumps easily.

Overall, if you are looking for a multi-purpose smartwatch for power users, Fitbit Versa 4 is an ideal option for you.

7. Google Pixel Watch

Google claims that Google Pixel Watch offers 24 hours of battery on a single charge. Although this claim is true, you can only achieve it through actively managing various features of the smartwatch.

In my tests, I was able to get around 20 hours of battery life on a single charge. It included GPS usage for tracking my running sessions which lasted for around 1 hour on average. If you use GPS on Google Pixel Watch all the time, you will get around 10 to 12 hours of battery life on a single charge. The overall battery life of the Google Pixel Watch is pretty decent and it will easily last for a full day if you manage it the right way.

In terms of features, Google Pixel Watch is equipped with advanced health features such as ECG, SPO2, heart-rate monitoring, stress and sleep tracking, automatic workout detection, and smart notifications.

In my experience, If you use the GPS feature for tracking workouts only and keep it off during normal usage, you can easily get around 48 hours of battery life on a single charge.

The Ignite 3 is also very feature-rich and you get features such as 24/7 activity tracking, heart-rate monitoring, workout tracking, personalized workouts, and many other fitness features.

Similarly, the watch is well-built and despite its plastic build, the watch feels sturdy and premium. The display of the glass is protected by Gorilla Glass and it can withstand minor bumps easily.

How To Get Better Battery Life Out Of Your Smartwatch?

If you want to get better battery life out of your smartwatch, you can follow these tips. I’ve personally used these tips and I was able to get better battery life.

  • Turn-off resource-intensive features: Smartwatches come with many resource-intensive features such as GPS, WiFi, and NFC which can drain your battery. So, when you are not using them, make sure that you turn them off and you will see a significant increase in the battery life of your smartwatch.
  • Don’t use Always-On-Display: Many Smartwatches these days come with Always-On-Display and this feature drains too much battery. So, if you want to get good battery life, turn off the Always-On-Display (AOD).
  • Use a Simple Watch Face: Smartwatches such as Galaxy Watches & Wear OS Smartwatches allow you to use third-party watch faces but many of them are not well-optimized which results in battery drain. So, make sure that you only use the ones from well-known companies. Preferably, you should choose simple watch faces because they don’t drain the battery.
  • Regularly Update your Smartwatch – Smartwatch companies regularly get feedback from their customers and they regularly release software patches and updates to fix known issues. So, if your smartwatch’s battery drains too quickly, you can report it to the company and install the latest updates to potentially fix the issue.
