Best Smartwatches With The Longest Battery Life For Heavy Users 2023

So, as I have mentioned, most Smartwatches come with a rechargeable battery and the period of time between charges relies on the use of it and the features that it offers. (usually between 1 up to 5 days).

For example, a fitness/activity tracker with a built-in GPS will make you need to charge it very often since a GPS is a big energy eater.

So, if battery life is an important issue for you then you should avoid a built-in GPS in your tracker and you can buy one that can sync with the GPS in your phone(you will have to carry your phone with you in order for it to work).

The activity trackers with the longest battery life are the ones with replaceable batteries( usually coin cell batteries like the ones in watches).

1. Apple watch series 8

Along with the longest battery life, the Series 8 will let you know if it notices an abnormal cardiac rhythm, loud noises, and a high or low heart rate.

It includes several high-end functions, including oxygen saturation (SpO2) reading, pressure tracking, increased pulse rate alarms, an Amazon Alexa constructed, sleeps monitoring, and others.

Best Smartwatches With The Longest Battery Life -Buying Guidelines:

You may now choose from a wide range of trackers with long battery life. Additionally, you can see whether it is within your budget or not.

However, while selecting a tracker, remember that if you want to use it for swimming, you should also ensure that it’s waterproof and capable of tracking your pool laps.

Most of the top smartwatches track fitness and offer other services like payment processing and text message replying. However, compared to activity trackers, smartwatches seem typically more expensive having even shorter battery life!

When choosing the top fitness and activity tracker, you should take the critical steps listed below:

The Factor Of Shape:

Unlike smartwatches, they have fundamental design ideas, and fitness. While some are finger rings or clip-on accessories, you can wear others on the wrist. But the vast majority of accessible fitness trackers are worn on the wrist. 

Smartwatches are more stylish if you prefer to wear the device on your wrist and may complement your wardrobe.


Activity trackers may be substantially less expensive than smartwatches right away in terms of price. The many features and priorities typically cause this.

Most fitness trackers offer fewer functions, but this is a plus rather than a con—fitness trackers are designed to be user-friendly, reliable, and good at obtaining data.

Although activity trackers offer benefits and drawbacks, they are frequently less expensive than smartwatches because of their practical form. Consider purchasing an activity tracker if you have a limited budget.

The Tracking Capacity: 

More sensors are often preferred because they enable you to measure more variables. Numerous internal processes, such as blood oxygen levels, sleep, the number of steps taken when walking, heart rate, and body temperature, can all be tracked by wearables. 

As a result, knowing your demands is necessary before deciding which gadget would be best for you.


You will depend on your monitoring device to provide information about numerous elements of your life. Therefore it must be able to give perfect measurements. 

Don’t expect flawless accuracy from fitness trackers and smartwatches because they are not devices that have received medical approval.

Battery Life: 

A tracker should have excellent battery life, which is true of most. Smartwatches typically have a lower battery life than particular fitness trackers.

Water Intransigence:

Water resistance is equally important when selecting a smartwatch or activity tracker. There are many options available when buying a water-resistant fitness tracker. Some watches only have splash proof coatings. Others can take a severe shower or can swim.

Size Of Display: 

Navigating between various functions is made more accessible by larger screens. More sophisticated trackers show words, numbers, and symbols on a watch face display. Others use an app or an LED light display to relay information.
