How Long Do Fitbits Last Before Replacement?
Most Fitbits last about 2 to 5 years, but the battery is what usually gives out first. Battery life starts to fade noticeably after 2 to 3 years of daily use, and once a charge no longer lasts the day, the device is near the end of its useful life.
The band, the screen, and the sensors can keep going for years. The battery is the weak link on almost every model.
Here is what to really expect, and how to stretch the life you have.
How long a Fitbit lasts on average
With normal use, plan on 2 to 5 years before you are shopping for a new one.
Newer models get about 5 to 10 days per charge when new. The Charge series often runs close to a week.
After 2 to 3 years, that same device may only hold a charge for a day or two. That drop is the battery wearing out, not a bug.
I will be honest with you here, because my family learned this the hard way.
My family’s real Fitbit track record
My family owned three Fitbits over the years. The battery life was poor on all three.
Every one of them died beyond repair much sooner than it should have for what we paid.
One was still under warranty, and Fitbit replaced it. The other two were out of warranty, so we were out of luck.
That pattern is why we stopped buying them. There is so much potential in the brand, but we have pretty much moved on. There are too many other options now.
I share that not to bash Fitbit, but so you go in with real expectations instead of hoping for five easy years.
What kills a Fitbit early
A few things speed up the decline.
Heat is the big one. Charging or storing a Fitbit in a hot car or in direct sun wears the battery down fast.
Always on displays and animated clock faces drain more power every day, which ages the battery quicker.
Water damage over time matters too. Even water resistant models are not meant for years of hot showers and pools without wear. Our guide on whether the Fitbit Versa 2 is waterproof covers what your model can take.
How to make your Fitbit last longer
You cannot stop battery aging, but you can slow it down.
Dim the screen or turn on auto brightness in the Settings app on the device.
Turn off the always on display if your model has it.
Switch to a simple clock face instead of an animated one.
Turn off SpO2 (blood oxygen) tracking if you do not use it.
Keep the charging pins clean, and never charge it in a freezing or baking hot spot.
If your battery is already draining fast, our guide on why a Fitbit loses battery so quickly walks through the fixes.
What the warranty actually covers
Fitbit gives a one year limited warranty in the United States. It covers defects in materials and workmanship under normal use.
In the UK and the European Economic Area, that period is usually two years under local law.
Here is the catch. The warranty does not cover the battery, because Fitbit treats batteries as consumable parts.
So a battery that simply wears out after two years is not a warranty claim. A device that fails from a defect inside the first year usually is.
When it is time to replace it
Replace your Fitbit when the battery will not last a full day, even after you turn features off.
Also replace it if it stops holding a charge, will not turn on, or your model no longer gets updates.
Before you retire it, pull your history off. Our guide on the symbols on your Fitbit screen helps you spot the low battery warning before it dies for good.
Frequently asked questions
Can you replace a Fitbit battery?
Not at home. Fitbit batteries are sealed inside and are not user serviceable. Opening the case damages the device and voids any warranty.
How many years should a Fitbit last?
Two to five years is realistic. Many people see the battery fade around the two to three year mark, which is often when they replace the device.
Does Fitbit warranty cover a dead battery?
No. Batteries are treated as consumables and are excluded. The warranty covers defects in materials and workmanship, not normal battery wear.
How do I get a longer life out of my Fitbit?
Dim the screen, skip the always on display and animated faces, turn off SpO2 if unused, and keep it out of extreme heat while charging.
I’ve had a Fitbit luxe 2 years now mine started having issues about 6 months ago. Not happy about that since it was $$
I noticed you did not list any sources for your report, beyond “scouring the depths of the internet”. I mean, I appreciate your doing that, but it would be helpful to know more about what your “scouring” consisted of.
I agree that reviewing customer feedback can be helpful, but it takes more information to put problems in perspective. For instance, if there are 100 problematic reviews of Fitbit Versa 2 it might seem like a lot. Yet, if Fitbit sold 10000 Versa 2, that’s only 1%.
I wish Fitbit did a better job of providing useful stats. I wish reviewers did, too.
Thanks.
Mostly forums, reddit, quora, etc. searching for common fitbit problems.
Unfortunately, having bought 3 different fitbits along with a few other brands to test, all 3 fitbit devices died within 18 months of purchase.
We always felt the one my wife was wearing daily to test was counting steps less that the others.
Had my Versa 3 for nearly three years. No problems with its functionality so far. But I have noticed lately that the battery is needing a recharge every two to three days.
I have a fitbit charge 2 that I bought in 2015 and I have worn on my ankle for most of its lifespan. I bought a new fitbit Christmas 2024 and I do not like it. I have resumed wearing the charge 2. In addition the charge 2 has been through the wash at least 10 times and also the dryer cycle once or twice. I wish I could buy a brand new one! But I soured on Fitbit anyway when they removed the steps competition from the software. It was motivating, and easy to do.
I must be a lucky one because I’ve had my Versa 2 for 2 1/2 years. I’m now where I have to charge it nightly. Not sure if I will continue with Fitbit products or not. ( I was thinking about the Versa 4, or newer model)
