Everyone will tell you smartwatch battery capacity vary brand to brand, battery life depends on the amount of usage. This is an obvious answer. However, we have found some stats.
Smartwatch batteries last up to 7-8 hours on average on a single charge without GPS and tracking, and the total lifespan is 2.5-3 years. However, in fitness trackers, we found battery lifespan up to 7-9 years.
Now let’s dive down into the confusion- how long does a smartwatch battery last?
Natural Life Cycle Of A Smartwatch Battery
Modern Smartwatch batteries consist of Lithium Ion batteries. It increases the total lifespan of a battery. Generally, Smartwatch batteries work up to 2-3 years which is an extended capacity than normal batteries.
There are mainly two types of batteries in a smartwatch – Lithium Polymer, and Lithium Ion. Lithium Ion is better than Lithium Polymer batteries.
It has more advanced power distribution and charging smartness.
Over time, brands are investigating to develop more powerful batteries. Whether smartwatches or smartphones people are expecting better battery life.

Chemically, battery capacity increment is not as easy as the user’s demand curve shows but wearable watch brands Apple, Fitbit, and Samsung are trying to offer the best version of battery life.
Fitbit offers a variety of ranges of battery life, the Fitbit Inspire 2 package says up to 10 days, and the Fitbit Ace 3 works up to 8 working days. Apple watch is manufactured to complete 1000-1100 charge cycles. That is nearly 2 and half years to 3 years of lifespan.
Samsung Galaxy watches are extremely serious about battery life however the last two updates are yet to be published.
On the Garmin Fitness Tracking, users can get 10-15 years of lifespan of batteries. In fitness tracker, battery lifespan is naturally longer than smartwatch due low power consumption than smartwatches.

The overall charge cycle is limited for a battery although it can be increased using some usability tricks.
Normally users change their smartphones or smartwatches after 2-3 years. Hence, it is sufficient because after this period of time the gadget would be outdated.
Battery Life Of Smartwatch: On A Single Charge
This is the most important part that you need to focus on. Every smartwatch has its individual battery life on a single charge. Here are some brand mentions of battery life.
On average, Huawei Watch GT 2 provides 7 days of battery life with enabling HR rate, GPS, and sleep tracking. Garmin Watch battery life works up to 10-14 days.
The Fitbit Inspire 2 lasts about 10 days, the Apple Watch lasts nearly 18 hours, and the Samsung Galaxy Watches are 22-24 hours.
These statistics are not the actual value of the battery capacity, this may fluctuate in real-life experience.
Quality of use defines the length of the battery life. Such as you can see different results without GPS, Always-On display, biometric tracking, and so on.
Brand Name | Battery Life |
Garmin Venu 2 | 11 Days Without GPS & Music, 22 Hours With GPS, And Other trackings |
Apple Watch Series 3 | 5-6 Hours |
Fitbit Sense | 6 Days and 4 Hours Without GPS and Tracking |
Apple Watch SE | 9-9.5 Hours With GPS and Tracking |
Fitbit Versa Active 3 | 6 Days and 8 Hours Without GPS and Tracking |
Apple Watch Series 6 | 7-8 Hours With Full GPS and Other Tracking |
Garmin Venu 2S | 10 Days Without GPS and Tracking 20 Hours GPS and Music Enabled |
Fitbit Versa | 3 Days and 5 Hours Without GPS and Tracking |
Generally, smartwatch batteries are made by Smartwatch brands but there are external manufacturers you can find on global sources, Grepow, Batteries4pro, etc.
Technically, smartwatches are built thinner and lighter than smartphones. Therefore the batteries are smaller than smartphones.
Battery Life Of Smartwatch: On A Single Charge
Modern smartwatches consist of Li-Ion batteries. Whenever you charge and turn on the smartwatch the battery usage starts right from there.
These are the main features that take most of the power usage-
- Tracking Sensors
- GPS
- Display
- Online Music Plays
- Bluetooth Connectivity
If you left your smartwatch without using these advantages then you can see nearly 1-2% battery usage after 3-4 hours.
How You Can Increase Smartwatch Battery Life
Disable Unnecessary GPS Tracking
You can see a lot of difference in battery life if you turn off your GPS tracking. GPS needs various types of network connectivity to operate as well as calculate the positioning.
Well, here you have full opportunity to take advantage of power saving. It’s weird if you need 24/7 hours of GPS tracking from your smartwatch.

Usually, users often use GPS tracking for 1-3 hours per day where only 10 minutes could be highly impacting to increase the power of the battery.
Turn-Off Always-On Display
Apple Watch Series, Samsung Galaxy watches, Fitbit, and OnePlus comes with built-in always-on display settings.
However, you can reset the settings from the settings of the watch or use the Fitness App of the respective smartwatch brand.
Some users have complained about the technical point of view of an always-on display. It sounds like the always-on display used to not be as bright when we raised our wrists to watch it.

That means the display becomes so deemed that one can not even see it.
But after raising the wrist the display brightness increases automatically without touching anything on the screen or side buttons.
The reason why we recommend turning off the Always-on display is nothing but to shut down the sensor of the display.
Manage Background Apps Synced With Smartphone
This is not only the problem of Smartwatches but smartphones, and laptops used to get slow, and are heavily power-consuming due to background apps.
With the help of Bluetooth, you can manage notifications like emails, WhatsApp chats, Facebook, and other social media, reply to messages, make or receive a call, etc.
Eliminate this connection while you don’t need it. By disconnecting the Bluetooth you can get more battery-saving opportunities.
Setup Display And Brightness
This is the most common practice that a user could do to reduce battery usage. The brightness level varies on the timing and places.

Outdoor travels are not possible with low brightness, on the other hand, you can decrease the level at night, more accurately after evening.
For decreasing your display brightness you can save the battery as well as your eyes.
Reduce Over Tracking
As we mentioned earlier, sensors are the most power-consuming element.
Your smartwatch is continuously recording different kinds of body movements, and internal health factors.
But you can track your daily activities wisely. Such as you don’t need to check your sleep often. Of course, if you are not suffering from sleep disease. But for the majority, sleep tracking is nothing but curiosity.
Step tracking or calories burnt are for workout hours, don’t track your steps during inactive hours. An accelerometer is not as smart as you think. Driving, skipping, and riding on escalator counts steps.
Hence, track when you intend to check your activities and performance.
Turning off smartwatches during sleep is beneficial for better battery life. Leaving smartwatches during sleep will reduce radiation effects on the body.
