That can be easier said than done, though, especially when life gets crazy and the last thing on your mind is stopping to check your device's battery level. You can take certain actions to make sure you never let your device's battery die completely — such as setting up calendar reminders based on the gadget's rated battery life and keeping the charging cord next to your bed — there's no denying that having a long-lasting fitness tracker puts you in a better position. Luckily, though, most of them use lower-power displays than smartwatches, so you'll be looking at about a week of battery life rather than a few days. All pricing in this article is current as of 2018 and is certain to change in the future. martin-dm / Getty Images Garmin Vivovit 3 Battery life: One year This device features a replaceable coin cell battery rated for a full year of use, so you won't have to worry about charging it up on a weekly (or even monthly) basis. This is far from the most advanced activity tracker available from Garmin, but the Vivofit does have some solid features, especially for more casual exercise enthusiasts. In addition to tracking and displaying your steps, distance, and intensity minutes on its backlit display, the wrist-worn Vivofit 3 tracks your sleep and automatically recognizes the type of exercise you're doing. You can receive reminders to get moving and track your activity progress on the move bar, too. Garmin isn't exactly known for its cutting-edge designs, so the style-conscious will be happy to know that the Vivofit 3 is compatible with a variety of bands, including options from Jonathan Adler and Gabrielle and Alexandra. Withings Activité Pop Battery life: About eight months Thanks to a button cell battery, this device gets you about eight months of use before you need to pop in a replacement battery. This is also a good option if you want an activity tracker that looks more like a standard wristwatch: The Withings Activité Pop features a traditional analog-style watch face, and you can choose from several different color options for the band. Fitness-tracking and health-related features include sleep tracking, a silent alarm that wakes you up with a vibration, standard activity tracking, and swim tracking. Fitbit Zip Battery life: Up to six months If you're considering purchasing a Fitbit device, the Fitbit Zip shouldn't necessarily be your first choice; its functionality is rather limited compared to other options such as the Fitbit Blaze and the Fitbit Surge. The Zip tracks only steps, distance, calories burned, and active minutes — not sleep or heart rate, among other things — but it's worth considering if you want to track only basic stats and need a long battery life. This tracker features a replaceable coin battery that lasts four to six months, so you won't have to worry about whether it will last you through the end of the week. Fitbit Charge Battery life: Seven to 10 days Not to be confused with the Fitbit Charge HR featured farther down on this list, this device tracks all the basic activity stats (from steps to calories burned), including sleep. It also features a silent alarm to wake you up with a vibration against your wrist, and when your (compatible) smartphone is connected to the Fitbit Charge via Bluetooth, you can view incoming call notifications on the device's display. This tracker is available in four colors: gray, black, blue, and burgundy. Samsung Galaxy Fit Battery Life: Up to seven days The Samsung Galaxy Fit is a nifty little gadget. On one hand, it looks, feels, and operates much like a Fitbit would, with smartwatch functionality taking a backseat to highly advanced fitness features. Given its emphasis on physical activity, it makes sense that the battery won't last you more than a week at a time. Between workouts, there's plenty of time to charge. Better yet, it connects seamlessly to other Samsung Galaxy products, so if you’re already rocking Galaxy Buds with your new S10, the Galaxy Fit is the perfect companion device, made better by its advanced notification features. You’ll also get Samsung’s much-lauded wellness monitoring which boasts everything from adaptable activity monitoring to heart rate, sleep, and even caffeine tracking. The Gorilla Glass face and the 5 ATM water resistance mean that, if you take it swimming, the Galaxy Fit probably won't drown. And the 120x240-pixel resolution of its ultra-vibrant AMOLED display is so crisp some would call it overkill. Jawbone UP3 Battery life: Up to seven days This option won't last you anywhere near as long as some of the other activity trackers on this list (we're talking about a week compared to several months). The upside, though, is that you don't need to buy replacement batteries: The UP3 features a rechargeable lithium-ion battery that takes about an hour to refuel via the included magnetic USB cable. It tracks sleep (and provides a breakdown of your time spent in deep, light, and REM sleep), along with steps, pace, calories burned, intensity level, distance, and active time. Idle alerts remind you to get up and move when you stay seated for too long, and a smart alarm wakes you up at the optimal time in your sleep cycle. Fitbit Charge HR Battery life: Up to five days While five days might seem like nothing compared to what you'll get with other activity trackers on this list, it's quite decent considering everything you can do with this device. In addition to providing all the usual fitness stats you'd expect from a Fitbit, the Charge HR monitors your heart rate and sleep stages, and provides more insight into your workouts than other trackers (including the Fitbit Charge, which offers many of the same features minus the heart rate tracking) by letting you see just how far you're pushing yourself at any given point. This tracker also incorporates some "smartwatch lite" features, including call notifications on your wrist. If you're training for a marathon or working toward specific fitness goals that involve measuring your heart rate, it could be worth the battery life trade-off — especially since the recharging process with the included cable isn't hard as long as you stay on top of it. UA Band Battery life: Up to five days This wrist-worn band measures stats including sleep duration and quality, resting heart rate, steps taken, and more. Like some others listed here, it provides activity alerts to get you moving when you've been inactive for a while. Other features include a vibrating smart alarm clock, the ability to control music playback when the UA Band is synced with your phone, and notifications for incoming texts, calls, calendar items, and more. It's all part of the HealthBox fitness-tracking system, which also includes a smart scale that measures weight, body fat, and progress toward your goal, and a heart rate band that measures your heart rate during workouts (the UA Band itself measures only resting heart rate). Samsung Gear Fit 2 Battery life: Up to five days Like the Fitbit Charge HR, the Samsung Gear Fit 2 offers continuous heart rate monitoring in addition to all the usual stats like distance traveled and calories burned. With the companion S Health software, you can set activity goals and create competitions with friends. This gadget also features smartwatch-style features such as app notifications, calendar alerts, and incoming call and text notifications on your wrist via the Super AMOLED display. Note that while the Gear Fit 2 is rated for up to five days of battery life, you may get just three or four, depending on how often you interact with the display.
