Why Does My Fitbit Sense Battery Drain So Fast? (Fixed)

Don’t know why does my Fitbit Sense battery drain so fast? Well, continue reading to know!

The Fitbit Sense has so many incredible features, so it’s easy to assume that when too many services are running simultaneously, the battery drains more quickly.

Well, the issue is not always related to one factor, rather it’s several reasons combined so let’s identify them all.

To address Fitbit Sense battery draining quickly, disable unnecessary background apps or trackers, limit notifications, and ensure charging from a reliable source.

Let’s unwrap some more details… 

Fitbit Sense Battery Life Draining So Fast – Why?

There are quite a few reasons for the short battery life of a Fitbit watch, even when the battery is not degraded due to long time usage.

Most of these factors will not impact the battery on their own, but when combined, the battery level will drop fast, making the watch hard to use…

• The screen timeout duration is set for too long.
• The always-on display mode is always enabled.
• Excessive usage of apps and notifications.
• The Fitbit watch is doing automatic detection.
• Heart rate monitoring is set to a high frequency.
• Background processes such as enabled GPS.
• The health of the battery deteriorates over time.

So let’s dive deep into the solution guide and solve the issue in minutes!

Why Does My Fitbit Sense Battery Drain So Fast? – Fixed Easily!

Information: A fully charged Fitbit Sense battery can last up to 6+ days depending on usage! 

1. Fully Charge the Fitbit Sense

The first and most important step is to charge your Sense battery completely.

The Fitbit Sense can take up to 2 hours to fully charge, and unplugging it early can reduce the usage period of your Sense battery. In addition, you need to verify the integrity of the electrical wall outlet.

Here is how to charge the Fitbit Sense correctly and fully:

1. Locate the Fitbit Sense watch (original) charging cable.
2. Plug the one end of the cable into a PC or USB adapter.
3. Plug the other end into the Fitbit Sense charging port.
4. Leave your Fitbit Sense on charging for 1 to 2 hours.
5. Use direct connection over (USB only) cable charging.

When your Sense is fully charged, track your activities as well as the battery drainage ratio to know whether the battery is performing normally.

In case the charge drops fast, keep reading!

Note: Avoid charging your Sense in extremely hot or cold environments!

2. Restart the Fitbit Sense Watch!

The Fitbit Sense may occasionally experience battery drainage issues due to software bugs or corrupted files, which gradually affect the OS and cause excessive battery drainage.

By doing a restart or “power cycle” on your Fitbit Sense, any temporal issues would be negated easily.

Here is how to power cycle the Fitbit Sense watch effectively:

1. Long press and hold the side button on the watch.
2. Keep holding the button for about 10 to 15 seconds.
3. Release the button when you see the Fitbit logo.

Turn on your Sense watch again by pressing the same side button, and then observe the Sense watch battery drainage period.

You can track the battery by noticing the significant decrease in Sense battery life compared to before.

3. Check for Fitbit App Updates

This may seem weird, but hear us out…

An outdated version of the Fitbit app prevents the Fitbit Sense watch from updating as well, which ultimately leads to skipping necessary updates.

Sometimes these updates carry scrips for an optimization of the battery, which you might be entirely missing.

• Simply check for any new updates and upgrade your Fitbit app version!

Here is how to check for Fitbit app software updates:

1. Note: Steps are the same for Androids and iPhones!
2. On your mobile, visit the Google Play or App Store.
3. Type “Fitbit” in the search bar “the magnifying glass”.
4. Check whether there is an “Update” button in there.
5. In case there is no update button, the app is up to date!

The process of updating your Fitbit app may take a few minutes, so be patient and wait for the process to complete.

Then restart the Fitbit Sense and your app mobile device and track the Sense battery life for any improvement.

In case this didn’t help, simply proceed onwards!

4. Adjust the Fitbit Display Settings!

There is no doubt that the Fitbit Sense is packed with amazing features.

However, the display settings such as screen timeout, always-on display, and screen brightness can consume a significant amount of battery power and reduce battery lifetime. 

The Solution? 

Adjust all of the Fitbit watch screen settings for battery optimization!

How to Adjust the Sense Screen Timeout Settings?

1. Navigate to Fitbit Sense Settings.
2. Find and enter the “Display” option.
3. Choose the option “Screen Time”.
4. Lower the screen timeout to 8 seconds.

How to Adjust the Sense Always ON Display Settings?

1. On your Fitbit Sense watch go to the Quick Settings.
2. Scroll down in the menu and find “always on display”.
3. Tap on the always-on display to turn the feature off.

How to Adjust the Fitbit Sense Brightness Settings?

1. Swipe left or right to access Quick Settings.
2. Look for the Brightness or Moon icon.
3. Use the + or – to set the brightness to a Low or Dim level.

Configuring these settings on your Fitbit Sense works wonders and increases battery life.

When you are done with checking everything, then test the battery drain time to track the results.

5. Reduce the Excessive Use of GPS 

If you rely heavily on your Fitbit Sense’s GPS feature to track and sync your outdoor activity data, keep in mind that it may contribute to faster battery drain.

In such cases, limiting GPS usage or turning the feature off completely, can greatly conserve the battery life.

Here is how to turn off the GPS in Fitbit Sense:

1. Open the “Exercise” app on the clock.
2. Swipe up from the screen’s bottom.
3. Navigate to Sense Exercise Settings.
4. Look for GPS and tap the toggle icon.
5. This will stop the GPS feature on the watch.

Note: Remember that the lifespan of your Fitbit Sense battery can vary depending on your usage patterns, settings, and the specific apps or features you use daily. 

6. Enable “Sleep Mode” at Bedtime!

If you wear your Fitbit Sense while sleeping to track your sleep, consider enabling Sleep Mode, which mutes notifications and changes the brightness of your Sense screen.

Ultimately this is only dimming and enhancing dark levels, but this will not affect your sleep track data.

How to Disable the Fitbit Sleep Mode?

1. Swipe right to access Quick Settings.
2. Navigate to the Quiet modes option.
3. Choose the “Sleep Mode” feature. 
4. Lastly, set a schedule for the interval.

When you enable sleep mode, it will disable features such as automatic screen wake and save battery power while tracking your sleep patterns.

If you have enabled snore detection on your Sense, know that this feature requires microphone access, which consumes more battery! 

How to Disable the Snore Detection?

1. Launch the Fitbit app on your mobile.
2. Locate and tap on the Sleep tile.
3. Click on the Settings gear icon from the top right corner.
4. Push on the toggle switch next to Detect Snoring.

This way you can save unnecessary use of your Fitbit Sense battery power!

7. Factory Reset the Fitbit Sense

If you have tried everything else and nothing helped, perform a factory reset on your Fitbit Sense watch.

Keep in mind that resetting the Sense will permanently erase all data and settings on your watch, so only use this method as a last resort. 

Here is how to factory reset the Fitbit Sense watch in easy steps:

1. Swipe right to navigate to Quick Settings.
2. Locate and tap on the “About” Sense option.
3. Choose and tap on “Factory reset” and wait.

When your Sense clock resets, simply pair it with your mobile in the Fitbit App to seamlessly take full control of your Sense clock features.

If you need further help or your Fitbit Sense battery continues draining fast, contact Fitbit Support.

Best of luck!

Quick Recap:

If you are wondering why my Fitbit Sense battery drains so fast, let your Sense fully charge for 2 hours, restart the watch, and update the Fitbit app.

In case that doesn’t help, optimize all display settings for low battery consumption and/or perform a factory reset. Visit us for more Fitbit troubleshooting guides!
