Most often users ask – Do smartwatch batteries reduce after sometimes of usage? This common question rises up for every rechargeable battery.
The following are the reasons that will help you to understand why over time batteries lose their power holding capacity, and finally comes to the end where you would have to replace it-
In short, the answer is yes, energy holding capacity in smartwatch batteries reduces after a couple of hundred charge cycles due to incomplete anion (negatively charged ion) emersion.
Why Smartwach Battery Lose Its Power Holding Capacity
Not only smartwatch batteries but every rechargeable battery loses its power holding capacity due to limited charge cycles. After a specific amount of charge cycle, electric flow is unable to produce a certain amount of electrons that reduce the energy supply in a battery.
It sounds complex right! Well, let’s learn it with a digestible explanation.
After a few revolutions, engineers have found a highly reactive element called Lithium.
Right now, most smartwatches, as well as smartphone batteries, are Lithium-Ion batteries (Li-Ion). It is basically Lithium-Cobalt-oxide as a positive cathode and Carbon as a negative anode.
During battery usage electrons (anion) flow from anode to cathode and it comes back to the anode when we charge in the battery.
This charging cycle can happen several hundred times after that the battery would start holding some electrons gradually. This causes a decrease in power holding capacity in a secondary battery.
If you want to increase the capacity of the battery back to normal you will need a proper chemical setup for the Lithium battery production.
Very few smartwatch users will do that. The most common solution to this problem is to replace the battery.
What Is A Charge Cycle In A Battery?
Except for primary batteries, every rechargeable or secondary battery has a limited count of charging. The process of completing a change from 0 to 100 is called one charge cycle where the unit percent(%).
The range of the cycle is 100 no matter how much battery is remaining such as if you charge your smartwatch from 20% to 90%, and charge-off the charge cycle will complete if you charge the remaining 30% next time.
Therefore, 1 charge may not be equal to 1 charge cycle.
A general misconception about the “charge cycle” is it’s a unit of time, however, it is wrong. The cycles state the overall lifetime of a battery.
To keep the smartwatch healthy, the charge cycle quality plays a vital role. Generally, Lithium Batteries stay healthy with “Shallow Charging” as it keeps the battery at normal temperature but “deep charging” is not healthy for good battery life.
Shallow Charging: Charging a battery at its optimum temperature, which is generally 20% to 80%.
Deep Charging: When you charge the battery in such a way that the battery temperature is used to increase more than 45°C. Charging battery at extremely low battery 0%-10% as well as high battery 85%-90% is considered as Deep Charging.
There are different level charge cycle limits available in gadget batteries. Let’s talk about it.
Charge Cycle Limit In Smartwatch Batteries
An average smartwatch battery holds a 250-350 Charge cycle which is 2-3 years of life span but under various conditions, their battery life might be decreased.
The condition, mentioned above, has experimented with different conditions such as voltage, temperature, current type (AC/DC). Hence, the number can vary a little.
On the other hand, we used to see more than 500 charge cycles in smartphones. That is pretty much normal according to the energy requirement.
Do not mix the number of battery charges with the charge cycle of the battery because you may not complete one charge cycle at a time.
Here is a series of answers to how you could calculate the life cycle of a lithium battery.
The total number of charge cycles is limited. No external tactics can increase the number.
Although we can follow a process to utilize the overall life span of the battery.
Before jumping into the process of saving battery we must know the following tasks.
Reason Why Smartwatch Battery Drains Fast
The main power-consuming sources of smartwatch batteries are Display, Tracking Sensors, and Live Network Connectivity. People lose batteries fast due to unorganized usage of the display, and activity tracking.
To know the random battery usage in a smartwatch consider the following questions-
- How Much Time You Spend On GPS Usage
- Are The Watch Faces Killing Battery Fast?
- When And How You Use The Tracking Sensors
How Much Time You Spend On GPS Usage
At every battery life test, GPS stands as a core battery-consuming feature in the smartwatch. Without GPS usage the battery seems 25%-40% better.
For the sake of usability, GPS in smartwatches feels cool but one can save a lot of battery usage by reducing the usage.
The main reason why GPS systems are used to extract more power is nothing but the live network connectivity. With 4G and 5G, the network condition sounds satisfying but the coverage issue is still a natural problem.
Lack of data downloading time requires more than normal battery usage.
Moreover, GPS connection increases the temperature of the battery due to the high amount of energy requirement in a short time.
Are The Watch Faces Killing The Battery Fast?
Wallpapers in smartphones, watch faces in smartwatches take lots of energy. Attractive watch faces snatch user attention.
But we can’t get both good battery life and eye-catchy wallpaper, at the same time.
Watch faces including high-definition pixels, colorful elements, and crispy backgrounds would not help you to save battery life.
In addition, being screen-sensors on, Auto changing watch faces seek more battery.
There is one solution to the problem. Depending on your mood and outdoor light brightness you can reset the watch faces.
When And How You Use The Tracking Sensor
Users often waste their energy on random activity tracking. In short, tracking sensors, work in different stages to record, calculate and execute the data.
This process takes a lot of activity from a smartwatch.
Sports mode for fitness tracking offers more than 15 types. Biometric tracking includes HR rate, blood pressure, sleep tracking, stress monitoring, and so on.
This activity tracking management is a temptation for the majority of the user. Oftentimes users used to apply it randomly.
However, this can be minimized with the help of strategic activity tracking.
- HR rate recording duration shortening the power usage
- Sleep tracking is not helpful every night all week
In addition, 24/7 hour step tracking is not a profitable option for your battery and tracking accuracy.

How To Increase Smartwatch Battery Life?
To increase smartwatch battery life we can take smart steps such as battery saver mode, CFOB charging, reset brightness and display settings, etc.
First of all, Bluetooth connectivity with smartphones increases battery usage. Background apps, GPS, phone calls, take a lot of battery.
On the other hand, online music listening is also a cause of battery reduction.
The whole process of battery life increment is involved several crucial steps
- Effective Charging
- Strategic Activity Tracking Usage
- Battery Temperature Management
- Display And Brightness Setting
Charge cycle and charge quality improve battery life. There are several important guidelines for using a battery in a smartwatch.
Check a detailed Guide on- How To Increase Smartwatch Battery Life?
After that, you can focus on activity tracking duration, usage of HR tracking, sleep tracking, blood pressure, and so on.
To take care of the battery. You must provide a healthy temperature to make it happy.
Display settings include brightness level, watch face selection, screen sensor, etc.
At last, system sounds utilize a certain amount of battery. Reducing vibration level, system sound put a huge impact on power saving.
