The Charge 4 comes in two editions; Special and Standard edition, the difference is that the Special edition comes with additional woven polyester straps and is available in a different color from the Standard edition.

Fitbit Charge 4 Features
- Decent Design
- Water Resistance Rating
- 7 Days Long Battery Life
- A Comprehensive Fitness Tracker
We’d expected a more sophisticated design especially after the acquisition by Google last year, but that isn’t the case. The Charge 4 looks exactly as the Charge 3 except for a slight discrepancy in dimension. Monochrome OLED still powers the display which isn’t so lively and interactive, but easy to read outdoor. A hardened glass covers the screen just like Charge 3, while the case is made of plastic resin which makes it very lightweight at 27 grams. Navigation is via touchscreen only. The straps are made of elastomer, but the Special Edition also comes with woven polyester straps in addition to the elastomer straps.
The Charge 4 is available in Standard and Special Edition. The Standard edition comes in black, rosewood/rosewood colors, while the Special Edition comes in black/granite colors.
Charge 4 is rated 5ATM which makes it waterproof up to 50 meters. So it safe to wear to the pool or ocean.
Fitbit claims the Charge 4 is tested to last up to 7 days with continuous heart rate tracking and about 5 hours with continuous GPS tracking. This is impressive which makes Charge 4 a great choice for tracking extreme workout activities.
Just like the Charge 3, the Charge 4 is well equipped with an altimeter, SpO2 sensor, accelerometer, heart rate sensor with the addition of inbuilt GPS which enables it to track the following activities.
– Track your heart rate continuously including resting heart rate and heart rate zones which gives you a clear picture of your intensity during training.
– Track calories all day.
– Track your complete sleep cycle and stages which include REM, deep and light, and time spent in each.
– Track floors climbed.
– Automatic exercise recognition with over 20+ preloaded workout modes to choose from.
– For women, log menstrual cycle via the app and monitor changes.
– Track your blood oxygen saturation via the SpO2 sensor.
– Sedentary reminders that monitors how active you’ve been and reminds you to move.
– Track your swimming activities which include SWOLF.
– (new) Active Zone Minutes allows you to set a target heart rate in which the device will alert you when your heart rate reaches a preset goal.
– Track your VO2 Max and overall fitness level.
– Guided breathing sessions can help you resolve stress.
Compatible with both Android and iOS devices, Charge 4 is able to keep you updated with all that matters to you such as SMS, email, and other notifications from both native and third-party apps on your phone. NFC that was restricted to only the Charge 3 special edition is now available to all models of the Charge 4. This allows you to make payment directly from Charge 4 with Fitbit Pay. Moreover, music control has also been added to Charge 4.
