Is The Fitbit Charge 4 Waterproof? (Clear Warning!)

This post may contain some affiliate links, so I’ll earn a small commission if you make a purchase using those links without any extra charge to you. Thanks if you do so, I appreciate it.

The Fitbit Charge 4 is a first for Fitbit; a first in that it finally added the much-needed GPS feature. While missing, GPS held Fitbit back from evolving its fitness wearables into the competitive atmosphere of industry giants, such as Apple and Samsung. Of course, GPS isn’t the lone feature.

The Fitbit Charge 4 is also waterproof for up to 50 meters, much like the Versa 2 and Versa Lite. You can technically term it as water resistant since it will give way once the water pressure reaches a certain limit, but unless you are deep-sea diving, you needn’t worry. 

Despite the shiny, new GPS feature, the Charge 4 is still, primarily a fitness tracker and that is exactly what it does. Since it is water-resistant to such depths, you can wear it while swimming (in lake, ocean, or pool), in the shower, bathtub, snorkeling, kayaking spending a day at the beach, or taking a dive in a river.

When you can take it for swimming there’s no reason why charge 4 will fail during hiking in rain or accidental water spills.

Regardless of what it is you do for fun or fitness in the water, the Charge 4 is always game on. 

How Long Can You Swim Underwater With Fitbit Charge 4?

But despite all these things, it is recommended to not swim 50 meters deep for a prolonged period, however, swimming for about 20-40 minutes anywhere between 1 to 30 meters will not do any harm but as you go deep the water pressure will increase and thus the time being spent decreases.

I am also saying this because when we swim our body is in constant movement especially our hands and legs. Though we wear the Fitbit charge 4 in our hands it faces un-static water pressure which in turn makes it ideal to not swim in the peak depth prescribed for more than a few minutes.

Where Not To Wear The Fitbit Charge 4?

Yes, Fitbit Charge 4 is designed to be swimproof, even though you should wear it in hot tubs and sauna because in a long run it can damage your device and may cause skin irritation because of coming into contact with shampoo, conditioner, and soaps so it is better to remove your watch and put it aside or in a locker before entering in the sauna room or a hot tub. Hot tub also means hot water springs and pools.

Waterproof Features of the Fitbit Charge 4:

When it comes to the water-based features of the Fitbit Charge 4, Fitbit only issues one warning, and that is to make sure that you completely dry the band whenever you are done, as some bands for Fitbit watches—especially some that come with it—don’t hold water well. 

You can simply find many waterproof bands for the Charge 4 for under $10 on amazon however, don’t just go and buy any – do spend some time reading the amazon reviews because there are Fitbit bands that are treated with chemicals that could cause rashes.

The Fitbit Charge 4 keeps track of many health and vital statistics while you are out on the water, especially if you are doing something strenuous, like swimming laps or trying to beat your previous swim times. 

  • Heart rate monitor
  • Blood/oxygen saturation
  • Skin temperature changes
  • 20 exercise modes

The heart rate monitor is pretty standard, but the oxygen saturation and skin temps may be pretty new to those who are upgrading from previous generations of Fitbit wearables. The 20 exercise modes don’t all include swimming, but many of them do.

You can also subscribe to Fitbit Premium, which brings a whole lot more to the table in terms of tracking and statistical information regarding your swim exercises and health. You get several things with Fitbit premium that have the potential to improve your swim workouts.

Here is the list of some that may attract you:

Guided Programs set you up for success by giving you the best advice on diet and exercise, including sleep and sleep tracking to help you maximize your energy levels in the pool or just out for a swim. 

Workouts provide you with lists of workout routines and how best to approach and execute them, including swimming as well. It includes over 200 workouts that are comprised of both video and audio. 

Advanced Insights will provide you with more detailed information on your activities, which includes all of your water activities, at least those that you choose to include. 

7 days battery backup in normal use and 4 hours when using built-in GPS though it vastly depends on conditions and usage in my experience, this battery is quiet for my overnight camping trips and a week-long survival trip in a tropical forest. Though still get a portable power bank to give it a boost of energy when it starts to settle in sleep.

Potential Risks That Can Damage The Precious Fitbit Charge 4:

First of all this device comes with a durable water resistance membrane but as it is not forever lasting, it will for sure diminish over time. However, if you don’t do any of these things then the water-resistance layer will remain intact for long enough that you’ll not regret it.

  • Dropping fitbit charge 4
  • Using the device in high velocity water sports or activities, that is why I don’t wear my watch in high flowing rivers but still a peacefully flowing river will not do any harm.
  • Expsoing it to perfumes, oils, sunscreen, deodrants, soaps, conditioners, shampoos, and insect repellents.
  • If you take it in anything other than fresh water then please wash it with clean water afterwards and dry it using lint-free cloth.

Final Thoughts

Not only is the Fitbit Charge 4 water-resistant, but it also comes with a ton of features, including the ability to separate it from your smartphone, since it now has its GPS. The Fitbit Charge 4 stands out as a premium, water-resistant device in the Fitbit lineup. 

Also, many worry about whether Fitbit can work in freezing temperatures or not then according to the brand itself the Fitbit Charge 4 is operable in temperatures as low as -20 degrees to -90 degrees celsius. So it will always be there to tell you when to stop swimming and other activities by sending you the heart rate notifications when it gets out of the beat for 10 seconds.
