How To Make A Smartwatch Battery Last Longer 

Smart gadgets like smartwatches are useful and trendy but highly power-consuming. The process of how to make a smartwatch battery last longer? consists of some crucial steps. 

To save batteries of a Smartwatch you need to follow-

  1. Take Advantage Of Internal Storage 
  2. Manage Brightness And Other Display Settings 
  3. Use CFOB Charging
  4. Track Only In Active Hours
  5. Avoid Unnecessary GPS Mode
  6. Battery Saver Mode Lengthen Battery Life
  7. Optimize Vibration And Other Functional Sounds
  8. Uninstall HPS Apps 
  9. Lithium Batteries Hate Temperature 

Take Advantage Of Internal Storage

The less you connect with random Wi-Fi or Bluetooth connection the less you would lose battery. 

High-speed network connectivity is used to satisfy our demand with the internet: speed and efficiency. 

But there is a difference between mobile networks and Wi-Fi or Bluetooth connectivity. The problem is neither smartphone nor smartwatch is capable of eliminating temporary network speed down with battery power consumption. 

Lengthen download time, surfing time, loading time drain battery life faster. In some cases, Wi-Fi does not work well with battery life as Ethernet.

In that case, James McInnes, On quora, has shared an interesting calculation. 

“…Wi-Fi consumes between 10 mW and 800 mW (transmitting full bandwidth); Wired ethernet consumes 50mW to 1W (full-duplex gigabit ethernet at full load). Wi-Fi uses 20% less power to transmit data at 50% the speed.

On a bytes-per-milliwatt basis, Wi-Fi is about 60% less efficient than wired Ethernet. In fact, WiFi is even less efficient in that there are more retransmissions and often additional encryption overhead…”

Therefore it would be right to take the advantage of your internal storage to listen to offline music. 

Nowadays, smartwatches are capable of storing images and documents and various formats.

Manage Brightness And Other Display Settings 


Display brightness management is a common practice to reduce battery usage but we don’t practice it effectively. 

Here are some effective settings you can try on your smartwatch-

  • During sunny days outdoor, display brightness: between (55%-70%) 
  • Cloudy Days outdoor, display brightness: between (40%-50%) 
  • Depending on the room brightness morning to afternoon brightness looks: (30%-45%)
  • At night (20%-33%) is enough 

Now, you may ask, what about the auto-brightness? Why we used to worry about the brightness level of our smartwatch all the time. 

Well, enabling auto-brightness does not reduce your battery usage. Instead, it allows your display sensor to work more actively to detect the environment’s light frequency and luminous intensity. 

If you want to save your battery you have to work one step further. 

Screen Off Duration 

This is ridiculous, we set a 30 minutes screen off duration. But after some time it transforms into a headache.

One of the main reasons batteries drain is lengthy screen-off duration. 

Generally, settings tables offer 5 sec, 10 sec, 15 sec, 30 sec, 1 minute, 3 minutes, 5 minutes, 10 minutes, 30 minutes.

If you are using a long screen off time for a certain time, reduce it after using it. 

Battery Friendly watch Faces 

High resolution and tight element watch faces are the reason for quick battery draining.

It’s hard to use watch faces with fewer elements, and black backgrounds but technically it reduces the usage of LED on the screen.

Depending on your watch brand you may find different black theme watch faces that will save your battery. 

Use CFOB Charging 

Charging affects battery life. Some habitual behavior can increase a smartwatch or fitness tracker battery life drastically.

To increase battery life we advise following a specific method which calls it- Charge For Optimized Battery Life (CFOB).  

In the CFOB method we- 

Completes 1st 3-5 complete change cycle 

Either smartphone or smartwatch it’s highly recommended to charge the battery up to 100% and dead it to 0%. By repeating this process 3-5 times you can increase the overall life of a battery. 

Charge-in Between 25%-75% 

To enlarge the battery life, you should charge the battery between the mentioned range (25%-75%). 

It’s a good practice if you are trying to charge near to 100% and reduce down to below 20%. 

Always Use Branded Adaptors 

Energy supply rate or power rating is one of the keys to good battery health. By using random adaptors you are throwing your battery in danger.

Smartwatch batteries are especially capable as smartphones to bear unnatural external power supply. 

Hence, you must keep the adapter always with yourself. 

After 1 and a half years, you can change your adapter with a new adapter from your watch brand store. 

Maintain The Temperature 

The gadget’s battery stays fit if you follow the ideal temperature guideline. 

Rechargeable batteries are not made to live in extreme cold (10°C<) or hot (50°C>). 

Therefore, don’t leave it in the sunlight for lengthy hours, or in the freezer. 

If you used to leave it at an unhealthy temperature it would start reacting with chemicals that cause ion reduction. 

Track Only In Active Hours 

Activity tracking or sensors stand in the 2nd position of the power consumption list. 

We don’t need 24/7 hours activity tracking on every feature. If you are in the gym, jogging, swimming, cycling track your activities using different sports modes. 

Eventually, step tracking needs to be tracked in a strategic way to improve the accuracy of tracking. Such as riding on accelerators, driving cars work as a tracking illusion for an accelerometer. 

Biometric sensors like Heart rate monitoring, sleep tracking, blood pressure helps us with a minimal amount of taking duration. 

Such as you need not track sleep every night. 

There may be two situations, one is for curiosity and another one is sleep disease. 

In the first case, you can check it once or twice per week. But if you are suffering from any sleep disease like insomnia still doctors will not recommend you to track every day. 

On the other hand, you can minimize the data recording duration of HR sensors. It will help you to manage and record your data for a specific time. 

Blood pressure, stress levels work simultaneously.

If you could make a schedule to track your behavior and analyze the results for a period of time, battery life will easily increase due to low processing time. 

In the beginning, users spend time exploring and testing the features on their wrist smart gadget but after a few days, you can apply a routine of tracking your fitness and health performance. 

Avoid Unnecessary GPS Mode 

At every battery testing session, we have seen that batteries in smartwatches last long without GPS or Bluetooth music. 

During global positioning, a smartwatch needs to connect with a live network. GPS can’t run without high-capacity internet connectivity. 

There are lots of stages where the processor would have to wait for the next piece of data from the web. 

Either 4G or 5G GPS will require a specific amount of energy from the battery. If you use GPS in a smartphone you may feel the battery temperature will be slightly high. 

It’s because of high volume energy usage in a short time. 

Now, here we can show some carefulness. Let me share a stat. 

With 1.5 to 2 hours of continuous GPS usage, you may lose 15% to 20% battery life. Although there are various conditions applicable such as screen brightness, sound volume, etc. 

You can make a drastic improvement in battery life without using GPS mode. 

There is no doubt that GPS mode is super useful especially in smartwatches and we are not recommending you not to use it but tactically. 

Battery Saver Mode Lengthen Battery Life 

First of all let’s clear a myth, battery saver mode doesn’t harm your battery health. It does not force your battery to spend less energy but shuts down the non-emergency features. 

To save the power of the battery, users can turn on battery saver mode while they are not using the smartwatch actively. 

Yes, it is a headache and does not go with regular user experience but it is helpful. 

In meetings or classes, you can turn the battery saver mode on. Turn it off when you are going to use it for more than normal duration small activities. 

How To Turn On Battery Saver Mode on smartwatch? 

The basic functions are pretty much accurate for all smartwatches- 

  • Swipe down or scroll down or else(depending on your watch brand) to open menu 
  • Go to settings 
  • Visit the battery section 
  • Scroll down 
  • Select the battery saver mode 
  • Turn it on 

Moreover, you can find different types of power-saving 3rd party apps. However, we never ever recommend any 3rd party battery optimizer for smartwatches as well smartphones. 

Most of the time, it affects your system and battery negatively. Therefore it is better to trust the function system of your smartwatch.

Watch OS is very strict on this topic; they hardly allow low-quality fancy apps on their system. 

Wear OS or Tizen OS users are habituated with tweaking their systems to work with more freedom. 

In both cases, 3rd party battery saver apps are not a healthy element. 

Optimize Vibration And Other Functional Sounds 

Ringtone, alarms, system volume reduction save battery usage. 

If you are still using silent mode you can make it better. Visit the settings > sounds > mode, and minimize the vibration sounds. 

Typing sound, the screen on bits, clicks can be silent. 

Now, test what works best for you, and apply it. 

P. S: If you need some crucial sounds then keep them turned on, instead reduce another functional usage from the smartwatch. 

Uninstall HPS App 

The HPS stands for High Power Consuming. 

In your smartwatch or fitness app you can check the power usage percentage. 

In apps like Facebook, Instagram, Snapchat, Tinder kills battery like a beast. During accessing these versions from your smartwatch you can welcome high battery usage. 

Monitor which apps are top of the energy consumption list. Thereafter you can minimize the usage of the particular application or simply uninstall it. 

Lithium Batteries Hates Extreme Temperature 

Right now most smartwatch batteries are Lithium-Ion batteries. And it hates extreme temperatures. 

There we had described why we should not charge a smartwatch over 90% or below 20%-10%. 

Now, what are the main reasons for increasing the temperature in a smartwatch? 

  • Long hour phone call, GPS usage 
  • Activity during charging 
  • After after healthy battery level (below 80%-85%) 
  • Charge-in extreme Low Battery (below 10%) 
  • Leaving the smartwatch in sunlight 

These practices would harm batteries in a smartwatch. Although extreme cold temperatures are also bad for battery cells. 

On OnePlus forums, developers and gadget lovers have shared their experiences with the safety limit of battery temperature. Where they have stated that above 50°C battery temperature would be a cause of worry.
