Wondering what’s new between the Fitbit Charge 5 vs. Fitbit Charge 4? Considered two of the best fitness trackers currently available, these activity bands are popular choices for novice step-counters and exercise enthusiasts alike.
Released about a year-and-a-half apart, the Fitbit Charge 5 and Fitbit Charge 4 serve a similar purpose in the brand’s device lineup. The Charge is the best Fitbit that’s not a smartwatch, and with each generation, the company tacks on a slew of improvements.
Fitbit Charge 5 vs. Fitbit Charge 4: Design
The Charge 4 looks almost identical to its predecessor, the Fitbit Charge 3. It has a sharp rectangular design with a grayscale OLED touchscreen, and silicone bands that strap around your wrist. A single touch-sensitive area on the left side of the Charge 4 acts as a Back button. It comes in black and a maroon-colored plastic case, too.
You’ll notice several aesthetic changes to the Charge 5. For one, it has a stainless steel case that comes in black, silver and gold. The metallic accents are more elevated, making this fitness tracker something you’ll actually want to wear outside of the gym. The curvier face also adds a fashionable touch.
In addition to a redesigned body, the Charge 5 has a color AMOLED touchscreen, which is two times brighter than the Fitbit Charge 4’s screen and offers an always-on option. It’s easy to see, even in direct sunlight. Color animations and notifications make Charge 5 feel more like a semi-smartwatch than a regular ‘ole fitness tracker, though there are plenty of low-cost activity bands that also offer a color display.
Fitbit Charge 5 vs. Fitbit Charge 4: Features
Both the Fitbit Charge 5 and Charge 4 are robust fitness trackers. You can use them to count your steps, track your heart rate throughout the day and review your sleep overnight. When you’re working out, they monitor your time elapsed and your distance traveled via GPS, when applicable. Though neither screen is large enough to see all the advanced metrics serious runners might want, check out the best running watches or best GPS watches for alternative options.
The Fitbit Charge 5 is more advanced than the Charge 4 with an electrodermal activity (EDA) sensor for detecting stress and an ECG sensor that can detect signs of atrial fibrillation. The ECG feature isn’t available at this time, though. Neither is the Daily Readiness score feature Fitbit announced alongside the Fitbit Charge 5. When it’s live, it’ll pull three different metrics — your fitness fatigue (activity), your heart rate variability (HRV), and your recent sleep — to tell you how ready your body is for exercise. This tool could be one of the major factor when deciding whether Apple Watch vs. Fitbit is right for you.
Fitbit took some features off the Fitbit Charge 5, too. It doesn’t support Spotify musiccontrols anymore and there’s no weather app. All guided breathing and relaxation sessions take place Fitbit app, while you’ll need a Fitbit Premium membership to access most of the mindfulness tools. Fitbit Premium also has more robust metrics, nutrition facts and guided exercises. Good news, you can usually try it out for a few months free when you buy a new Fitbit device.
Fitbit Charge 5 vs. Fitbit Charge 4: Battery life
Though Fitbit estimates both the Charge 5 and Charge 4 have seven days of battery life, your experience will differ based on how you use your fitness tracker. If you decide to have GPS, heart rate monitoring and the always-on display turned on all the time, you can probably expect to charge your tracker every couple of days.
Fitbit Charge 5 vs. Fitbit Charge 4: Which should you buy?
Now that you know the key differences between the Fitbit Charge 5 vs. Fitbit Charge 4, the model you decide to buy depends on what you’re looking for out of a fitness tracker. If you’re new to fitness tracking, and don’t need ECG or a color display, the Fitbit Charge 4 is a steal for the price. Plus it’s evenly matched with the Charge 5’s activity tracking features at the moment.
When the Fitbit Charge 5 gets all its features, it might be more worthwhile than the Charge 4. Not to mention, once a Fitbit model starts going on sale, you will typically find it for less from then on out.Kate Kozuch
