Fitbit has included a long-overdue upgrade to its flagship fitness tracker: a built-in GPS. The Charge 4 comes with a built-in GPS so you can track and record your distances, steps, and pace in real-time even without your phone. It also features a map that shows the intensity of your exertion at certain points of your workout, cycling, or training.
On the other hand, the Inspire HR needs to be connected to your phone’s GPS to be able to track and record the aforementioned data. If you don’t mind carrying your phone with you all the time, then this isn’t a big issue.

Battery Life and Additional Features
The

Long battery life is imperative if you want to consistently monitor your heart rate. You can wear your Fitbit for days, and even during your sleep, thanks to their strong battery life. At full power, the Charge 4 can last for up to 7 days while the Inspire HR only lasts for up to 5 days. However, keep in mind that frequent or continuous use of the Charge 4’s GPS will yield significantly shorter usage hours.
As they both have a 5ATM certification, this means that the Charge 4 and the Inspire HR can be submerged for up to 50 meters of freshwater. This allows you to track and record your sets, pace, distance, and intensity while doing water activities such as swimming, surfing or rowing. However, they are not recommended for use in saunas or hot tubs. Something to consider when choosing a Fitbit band for your water activities is the woven bands don’t dry as fast the classic bands.
