Fix it: Dealing with battery drain issues on Charge 4 & other Fitbits

Fitbit devices are known for their excellent battery life. But what should you do if the wearable is not holding charge? There’ve been complaints in particular about Charge 4 battery drain. This article is part of our series on how to fix common issues.

To start off – make sure you do this first

First off you should make sure you’re charging your device properly. Have a read through our article that explains what to do if your Fitbit activity tracker or smartwatch is not charging. It provides a few solutions to try out such as:

  • restarting your tracker,
  • cleaning the device and charging cable,
  • making sure the USB port or outlet is not faulty and
  • making sure the tracker is connected securely to the charging cable.

Fitbit says that is also not a good idea to charge your device in extreme heat or cold. It might impede with the charging process.

Finally, make sure you have the latest software issue installed. A good example is Charge 4. In early 2020 there were lots of complaints of Charge 4 battery drain issues. It turns out the culprit was a software glitch. Once users installed the new firmware update everything returned back to normal.

However, if you tried all of the above and are still having problems – try one of the solutions below.

Dealing with battery draining issues on a Fitbit

The length of time your Fitbit wearable operates depends on how frequently you use it and various settings. Here’s a table illustrating what to expect with normal use.

If you’re not approaching these sorts of numbers there are a few things you can do. But before you do any of this restart your device – that often solves any issues you might be having.

Ace series, Alta and older Inspire devices

The Ace series, Alta and older Inspire devices have an advertised battery life of around 5 days. If you’re struggling to achieve this figure try one of the following:

Turn off the option to wake the screen when you turn your wrist. On Ace, Alta and most older devices this is done by turning off the Quick View option in the Fitbit smartphone app. On more recent wearables, this can be done from the device itself. For example on Ace 2 and Inspire, press and hold the side button, then choose the Screen Wake setting and switch it off.

Turn off the option to receive notifications from your smartphone. If you receive a large amount of notifications, this can drain the battery.

Receive fewer reminders to move by tweaking the settings. You can also switch off these reminders, along with alarms which also reduce battery life.

Alta HR, Inspire HR and 2, Blaze

An Alta HR or Blaze can keep going 5 days between charges while Inspire HR’s advertised battery life is 7 days and Inspire 2 10 days. All of these have a heart rate sensor, so in addition to the solutions above you can turn off the Heart Rate setting if you don’t need heart-rate tracking day and night.

It’s worth mentioning. Inspire and Inspire HR devices have been known to be plagued by battery life issues. Have a look at our article offering a few additional solutions. The culprit of the problem seem to be certain clock faces.

Charge series

The suggestions for the Charge series are no different from the list above. The one additional thing to try is to use guided breathing sessions less frequently. This is because multiple sessions per day may reduce battery life. Fitbit Charge 3 should last up to 7 days between charges, and Fitbit Charge 2 around 5 days.

GPS issues

It’s a bit different with Charge 4. It comes with the addition of built-in GPS. Using this function drains the battery quite a bit. Switch built-in GPS on and the battery life comes down from 7 days to only 5 hours.

As mentioned, users have complained about Charge 4 battery drain issues. Make sure you have updated your firmware to the latest available version. Also, try to turn off your GPS feature and see if the battery lasts more time.

If you’re running low on battery juice and want to track your exercise – you can always switch to Connected GPS. The GPS won’t be active if you start an exercise from the smartphone app. This is much easer on the battery. If you forget to turn GPS off after exercising, it will eat up what’s left of the battery life.

Flex 2

You can use a Flex 2 for up to 5 days without reaching for a charger. Tweaking the notifications, alarms and reminders options are ways to extend battery life. One other thing you can do is make sure the swim detection feature is off when you’re not in the pool.

Ionic, Versa series & Sense

An Ionic battery lasts about 5 days and Versa’s around 4 days for the older devices and 6 days for the newer ones. Sense is on par with Versa 2 and 3.

The solution is as above. Switch off the wake the screen option, change the heart rate setting, turn off notifications, receive fewer reminders to move and reduce the number of alarms you use.

It’s worth noting, you will need to charge your device more often if you play music or use the music controls frequently, if you use apps that keep the watch’s screen on access the internet a lot, or if you use an interactive or animated clock face. As mentioned, the use of the built-in GPS on Ionic, Versa 3 and Sense is a particular drain on the battery.


Fitbit One lasts two weeks between charges. A few years old, this is a simple device that only provides the basics when it comes to tracking fitness. Fitbit’s only suggestion for extending battery life is to switch off or reduce the number of alarms.


Well done if you’re still holding on to your Zip. The device is ancient now.

Not much you can do here apart from checking your stats less frequently. The Zip operates on a 3V coin battery (CR2025), that should last six months.
