The Top 10 Ranked by Battery Life (January 2021)

Based on reviews posted on popular review sites as well as from Fitbit Inspire's website, Fitbit Inspire performs very well in terms of battery performance relative to other fitness tracker brands.

The review site techadvisor.co.uk gives Fitbit Inspire excellent ratings for battery performance in a review posted on its website. Here's a brief quote from this review:

Battery-wise, Fitbit claims the Inspire should last five days, and that was borne out, almost exactly, in our testing. In fact it died after five days and one hour of moderate use.

The review site trustedreviews.com gives Fitbit Inspire excellent ratings for battery performance in a review posted on its website. Here's a brief quote from this review:

Fitbit rates the battery at five days, which felt about right during my testing. I’d have expected the Inspire to last a little longer than the Inspire HR considering the lack of HRM, but they’re identical in terms of stamina.

Based on a review posted on digitaltrends.com, Fitbit Inspire was rated as fairly average for battery performance relative to competing fitness tracker brands. Check out the entire review here. Here's a brief quote from this review:

Fitbit claims the Inspire HR will deliver up to 5 days of battery life but my experience was not as optimistic. I averaged three days of juice when using the tracker for daily one-hour workouts with connected GPS, frequent incoming alerts, 24/7 heart monitoring, and overnight sleep tracking.

Based on reviews posted on popular review sites as well as from Fitbit Charge's website, Fitbit Charge performs very well in terms of battery performance relative to other fitness tracker brands.

The review site trustedreviews.com gives Fitbit Charge excellent ratings for battery performance in a review posted on its website. From this review:

On the battery front, its nice to some improvements even if its not as radical as offering the same six months as the Fitbit Zip. Fitbit’s trackers have historically performed better than the claimed battery life, at least by a few extra days. The Charge promises 7 to 10 days and wearing it continuously using the stopwatch features and regularly checking progress it’s definitely nearer the latter. Disabling alarms and reducing interaction with the display will certainly help preserve the battery life.

The review site runnerclick.com gives Fitbit Charge excellent ratings for battery performance in a review posted on its website. Specifically, this reviewer pointed out the following:

This smart fitness watch has a long lasting battery. It lasts longer than competing trackers with a battery life of 7-10 days, depending on how much you use it.

Based on reviews posted on popular review sites as well as from Fitbit Alta's website, Fitbit Alta performs very well in terms of battery performance relative to other fitness tracker brands.

The review site runnerclick.com gives Fitbit Alta excellent ratings for battery performance in a review posted on its website. Specifically, this reviewer pointed out the following:

One of the exceptional aspects of the Fitbit Alta is its battery life. To get a full charge takes just 2-3 hours, and power last for up to five days (or longer, according to many users).

The review site theverge.com gives Fitbit Alta excellent ratings for battery performance in a review posted on its website. From this review:

Fitbit has set battery-life expectations for the Alta at five days per charge.

One reviewer on tomsguide.com said Fitbit Alta performs well on battery performance relative to its peers. You can read the full review here. Here's a brief quote from this review:

Fitbit says the Alta will last five full days and nights on a charge, and that claim held up during my testing. I charged it up to 100 percent on Wednesday afternoon, and used the wearable about every hour or so. By Monday afternoon, the Alta's in-app battery indicator showed that the wearable had about a third of the battery left. That's longer than the five days promised.

Based on reviews posted on popular review sites as well as from Fitbit Ace 2's website, Fitbit Ace 2 performs very well in terms of battery performance relative to other kids smartwatch brands.

The review site techadvisor.co.uk gives Fitbit Ace 2 excellent ratings for battery performance in a review posted on its website. Here's a brief quote from this review:

Battery life is around 5 days, which is reasonable, and fairly typical for the Fitbit range.

The review site digitaltrends.com gives Fitbit Ace 2 excellent ratings for battery performance in a review posted on its website. Here's a brief quote from this review:

The Ace 2 has a promised five days of battery life, and I found the estimate to be close to real-world use, but not exactly five days. My kids preferred the animated displays, so battery life was often three to four days. Still, the encouragement they received from the animations was worth the tradeoff.

Based on reviews posted on popular review sites as well as from Fitbit Ionic's website, Fitbit Ionic performs very well in terms of battery performance relative to other fitness tracker brands.

Based on a review posted on techadvisor.co.uk, Fitbit Ionic was rated as fairly average for battery performance relative to competing fitness tracker brands. Check out the entire review here. Here's a brief quote from this review:

When it comes to battery life, the Ionic should last for four days on one charge, which is more than some of its rivals. However, when you start using GPS you’re looking at a dramatic loss in battery life, down to 10 hours if the GPS is on all the time, which is something to keep in mind. If you also have your screen set to always on during a run, Ionic will last just five hours - that said, if you've been running for five hours you too deserve a rest!

The review site tomsguide.com gives Fitbit Ionic excellent ratings for battery performance in a review posted on its website. Here's a brief quote from this review:

Other smartwatches offer sleep-tracking apps in their app stores, but few have the battery life of the Ionic. My device lasted about three days on a charge, and that included 30-45 minutes of daily GPS use in the Exercise app and Pandora music playback. Fitbit promises the Ionic will last up to four days on a charge, or 10 hours with continuous GPS use. I have to charge my Apple Watch Series 2 every day after putting it through the same amount of exercise tracking and music playback.

The review site cnet.com gives Fitbit Ionic excellent ratings for battery performance in a review posted on its website. From this review:

Fitbit Ionic has a better-than-most-smartwatches four-day battery life, while still having always-on heart rate and a comfy fit. It has features galore: waterproofing, GPS and on-wrist mobile payments, plus new watch faces and a growing app store. It works with iOS and Android, and has an excellent phone app and social community.

The review site trustedreviews.com gives Fitbit Versa excellent ratings for battery performance in a review posted on its website. Specifically, this reviewer pointed out the following:

The Versa’s stamina truly puts other smartwatches in the shade. Fitbit says you can expect the watch to last for at least four days off a single charge, but real-life results show that to be a conservative estimate. In testing, the Versa comfortably kept going beyond four days. When it was connected to my phone via Bluetooth, it lasted five days; when it was untethered, it managed six days. What’s more, if you want to extend that even further, you could set the screen’s brightness to dim rather than automatic or bright.

Based on reviews posted on popular review sites as well as from Apollo Neuro's website, Apollo Neuro performs very well in terms of battery performance relative to other wellness wearable stores.

The review site alexfergus.com gives Apollo Neuro excellent ratings for battery performance in a review posted on its website. Here's a brief quote from this review:

Generally, I’ve found that the Apollo device has excellent battery life, giving me two or three days between charges even when using the unit for 120 minutes each night at bedtime. Charging the unit up from a drained state takes about two hours.

Based on a review posted on michaelkummer.com, Apollo Neuro was rated as fairly average for battery performance relative to competing wellness wearable stores. Check out the entire review here. From this review:

I’ve noticed that when I use Apollo for two hours at night at 80% intensity, and for 15 minutes in the morning at 60% intensity, the battery drains to 85%. With additional use throughout the day, I typically end up charging Apollo (using the provided micro-USB cable) once a day. Overall, I wish that the battery would last a bit longer so I wouldn’t have to charge Apollo so frequently.

Based on a review posted on amazon.com, Martian mVoice was rated as fairly average for battery performance relative to competing hybrid smartwatch brands. Check out the entire review here. Specifically, this reviewer pointed out the following:

The battery life is more than adequate, probably 5 days with use. I Just got back from a 4 day vacation where I left the watch at home and it still had more than 50 percent charge. I think it is likely that the smart function battery could last a good week with mild use. Of course, the real beauty of the device is that even if the battery does discharge completely, you still have a very nice looking retro style watch that as it happens is extremely comfortable to wear. With a round face, no less.
