Best Smartwatches with the Longest Battery Life in 2021


It is highly frustrating to see your smartwatch run out of battery when you are in the middle of a workout session, cycling, or even during a walk. Checking the battery backup of a smartwatch is something many people ignore when buying one.

From sharper screens to more health features, there’s a lot to consider when getting a smartwatch and one of the most important features to look out for is battery life.

Thus, we have listed here some of the best smartwatches with really long battery life:

Apple Watch Series 6 and Apple Watch SE:

The Apple Watch Series 6 and SE are smartwatches that can do a lot. Although the Series 6 doesn’t have many new features over its predecessor, there are some features worth noting, like the power-efficient S6 chip, blood oxygen monitoring, heart rate monitor, ECG and dual-band Wi-Fi.

The Apple watch SE also shares many of the Series 6 features minus the Blood Oxygen sensor and ECG features. However, they also share many other features such as handwashing reminders, sleep tracking and runs on the latest WatchOS 7.

The Apple Watch has decent battery life compared to most other smartwatches in its category. Apple claims the Watch Series 6 and SE are both tested and provide an 18-hour battery life on a full charge.

This applies to the Series 6, even with the Always-on Display that is now 2.5 times brighter than the previous generation of Apple smartwatches. The SE does not have an Always-On Display.

Both devices can easily charge up to 70% in an hour. They have a magnetic charging cradle that comes with the watch in order to charge it. Another clever touch is that your iPhone also receives a notification when your watch’s battery is fully charged.

The Apple Watch Series 6 price in India starts from Rs.39,990, and the Apple Watch SE starts at just Rs.29,900

Samsung Galaxy Watch Active 2:

The Samsung Galaxy Watch Active 2 is a must-have for anyone looking for a high-end Android-based smartwatch. It is an excellent smartwatch with loads of features bearing a speaker and a touch-enabled bezel that really helps with the overall experience.

It can monitor your Heart-Rate, track Fitness Activities, Blood Oxygen Levels, and measure Sleep Quality accurately with its ultra-sensitive sensors. The Galaxy Active 2 comes with both GPS and LTE connectivity for those who need it. Overall it’s an impressive all-around smartwatch for the Price.


Battery longevity will also depend on your usage patterns. With the 40mm watch, Samsung claims its 247mAh battery will last for around 36 hours on a single charge, while the 44mm device with its larger 340mAh battery can last about two days with heavy usage.

Two days isn’t too bad for a smartwatch, but it’s nowhere near Fitbit or Amazfit levels. However, the watch will last a bit less than 36 hours if you have the always-on display turned on at all times.

The Samsung Galaxy Watch Active 2 price in India is Rs.30,990.

Fitbit Versa 2:

Stylish and sturdy, the Fitbit Versa 2 scores really high in terms of its stylish looks. With the always-on display mode of the smartwatch, your information is just a glance away during workouts or workdays.

The Fitbit Versa 2 tracks all-day activities like steps, distance, active workouts and calories burned to show how much you have progressed, helping you get closer to your goals.

The Price of the Fitbit Versa 2 is Rs.13,999!

Samsung Galaxy Watch Active 3:

The Samsung Galaxy Watch 3 adds a wide variety of watch faces to your life with depth and lighting effects. It features a circular design that can make any watch face look good.

It even has a set of analogue watch faces that mimic realistic watch hand shadowing and ticking sounds to give you the feel of an actual watch. The Galaxy Watch 3 comes with a full-blown music player and onboard storage so you can carry your playlists wherever you go.
