Fitbit Charge 5v Inspire 2: Design

Fitbit Inspire 2

With these trackers sitting at opposite ends of Fitbit’s tracker spectrum, there are some big differences on the design front.

The Inspire 2 is the thinner of the two trackers, making it lightweight and comfortable to wear 24/7, including when you sleep.

It features a plastic case accompanied by a removable silicone band with the option of black, white or pink colored bands. Like the other Fitbits, there is also a huge range of additional bands to redeem.

Unlike the Charge 5, you don’t just have to wear it on your wrist. A clip accessory lets you wear it on a belt or under your clothes for more discreet tracking.

On the Charge 5 you get a class-leading aluminum casing, with a removable silicone band along with a range of other official Fitbit bands on offer. Like the Inspire 2, it’s been slapped with a 5 ATM water resistance rating allowing you to submerge them in water up to 50 meters, making it safe for swimming.

In terms of interacting with these devices, the Inspire 2’s case can be pressed to wake up the display or go back one screen. It’s a similar story for the Charge 5, which houses haptic control and further includes stainless steel panels to provide the ability to take ECG and EDA readings.

There are big differences on the display front with the Charge 5 featuring a full AMOLED color touchscreen, which offers an always-on mode.

The Inspire 2, on the other hand, uses a grayscale display which helps Fitbit deliver strong battery performance, but we encountered some issues with visibility in direct sunlight. A bright screen mode makes it better suited for indoor viewing, you might struggle to always see it clearly outdoors.

The Inspire 2 is the thinner and lighter of the two, offers more versatile wearing options, and also offers the ability to mix and match strap options. The Charge 5 gives you a superior color screen, the same sort of customizable strap options, and nicer case materials if you’re not a fan of the all-plastic look of the Inspire 2.

When it comes to tracking your steps, sleep, health, or exercise, these two trackers are capable of covering all of those things. Although it’s clear that the Charge 5 can give you more in some of those departments.

On the sensor front, both use a 3-axis accelerometer to track steps, select indoor and outdoor activities, and enable sleep monitoring.

sleep tracking

In terms of sleep tracking, these two trackers offer an almost identical experience, and Fitbit’s sleep tracking is one of the best in the business.

Both devices offer a breakdown of the time spent in sleep stages and the duration of your night’s rest. You can also find additional data such as sleep heart rate and restlessness data through Fitbit’s premium subscription service.

However, only the Fitbit Charge 5 will track nighttime blood oxygen through its SpO2 sensor – which can be an indicator of sleep disorders such as sleep apnea.

Fitness Tracker and Sports

For those basic fitness tracking features, both can track steps, distance traveled, calories burned, and trigger inactivity alerts.

There are optical heart rate monitors on both trackers to continuously monitor heart rate, including during sleep, and to measure exertion levels during exercise.

When you want to track exercise, both Fitbits offer the same Over 20 goal-based exercise modes, including running, cycling, walking, and pool swim tracking.

The built-in heart rate monitor provides information such as active zone minutes, cardio fitness levels, and displays intensity maps in the Fitbit app. This allows you to quickly see the sections of your route where you’ve really worked hard.

The Charge 5 additionally offers Daily Readiness Scores, which are based on activity tracking, heart rate variability metrics, and the latest sleep tracking to tell you if you need to tackle a problem. hard workout or take a day off.

Two great features you only get on the Charge 5 are built-in GPS and an altimeter for measuring elevation. The Inspire 2 offers connected GPS, which means overlaying your smartphone’s GPS signal to track runs and cycles, but accuracy suffers.

Only the Charge 5 uses red LEDs and infrared sensors to enable SpO2 monitoring during sleep.

It also has an ECG sensor for more accurate heart rate readings and a skin temperature sensor to monitor skin temperature during sleep.

So while you get those tracking basics on both devices, the Charge 5 gives you great features like ECG, built-in GPS, an altimeter, and the ability to measure blood oxygen while you sleep.

All of Fitbit’s wearables are designed to help you pay more attention to your mental well-being as well as your physical well-being.

With the Inspire 2 you get guided breathing programs on the band itself, then you’ll find more mindfulness features in the Fitbit companion app, including the ability to generate stress measurement scores based on physical signs of stress. These scores are generated from resting heart rate, sleep, and recorded exercise and activity data.

There’s also female health tracking and access to meditations and sleep soundscapes, with additional features requiring Fitbit’s Premium subscription service.

The Charge 5 also offers these features, along with the addition of an EDA analysis app that can measure the body’s response to stress.

If you want the best Fitbit has to offer here, you’ll get it from the Charge 5.

That being said, many of these features are inside the Fitbit companion app, which the Inspire 2 also has access to.

Both of these trackers can run smartwatches, but their designs and the hardware they can hold dictate how useful they are when you’re not counting steps or doing guided breathing.

The Charge 5 has that larger color screen to show notifications for iPhones and Android phones, the latter supporting quick responses to those notifications. There are also music controls for Spotify, watch faces, and Fitbit Pay for making contactless payments. If you care about silent alarms and setting sleep and do not disturb modes, that’s also covered here.

The Inspire 2 also has clock faces and the ability to show notifications for both native and third-party apps and it also offers Fitbit’s Tile integration. This makes it easy to locate your tracker with your phone when you’ve misplaced it.

The Charge 5 clearly gives you more smartwatch functionality, but if you’re mainly concerned about not missing phone calls, you’ll get a pretty good experience on the Inspire 2.

Fitbit Charge 5v Inspire 2: Battery life

For the tracker that will give you the best battery life, you want the Inspire 2 on your wrist. Up to 10 days, it offers the best battery numbers available on a Fitbit right now and that includes its smartwatches.

The Charge 5 in comparison offers up to 7 days, so it’s good for a week, but may struggle to get more or even deliver less if you use it with the screen in always-on mode and using SpO2 monitoring.

Charging both from 0-100% will take around 2 hours, so they’re not the fastest chargers and lack the fast-charging technology that Fitbit has rolled out for its Versa 3 and Sense smartwatches.

If you can live without a color screen and features like ECG and skin temperature monitoring, you’re still getting a solid experience from Fitbit’s budget option that’s comfortable to wear 24/7. /7.
