The Fitbit Charge 6 and the Amazfit Band 7 both clip onto your wrist and count your steps, but they are built for different shoppers. One is a full health tracker with GPS and payments. The other is a bargain band that trades features for price and battery life.
Here is the short version: buy the Charge 6 unless the price scares you off, in which case the Band 7 covers the basics for a third of the cost.
Key Differences
- GPS: The Charge 6 has built-in GPS + GLONASS, so it maps your runs and rides without your phone. The Band 7 has no GPS at all and must borrow your phone’s signal for distance.
- Payments: The Charge 6 has NFC for tap-to-pay at the register. The Band 7 does not.
- Health sensors: The Charge 6 adds ECG (heart rhythm), EDA (stress), blood oxygen, and a skin temperature sensor. The Band 7 sticks to a standard optical heart rate sensor.
- Battery: The Band 7 lasts about 18 days per charge. The Charge 6 lasts about 7 days.
- Screen and price: The Band 7 has a larger 1.47-inch display and costs $49.99. The Charge 6 has a smaller 1.04-inch display and launched at $159.95.
Deep Dive Comparison
Design & Comfort
Both bands are light and easy to forget on your wrist. The Charge 6 weighs 30 grams in an aluminum, glass, and resin body with a 36.73mm case. The Band 7 weighs 28 grams in a polycarbonate case that measures 47.4mm, so it reads as a taller, plastic-feeling band with a bigger face. Both carry a 5 ATM water rating, so showers and pool laps are fine for either one. If you want the more premium feel, the Charge 6’s metal-and-glass build wins. If you want the bigger screen for glancing at stats and notifications, the Band 7 gives you more real estate.
Battery Life
This is the Band 7’s clearest win. It runs about 18 days on a charge in normal use. The Charge 6 lasts about 7 days, which is still good but means charging roughly once a week. The catch is GPS: the Charge 6 gives you about 5 hours of built-in GPS tracking, while the Band 7 has no GPS to drain, so its long life comes partly from doing less.
Health & Fitness Features
The Charge 6 is the real fitness tool here. It tracks heart rate with an optical sensor, adds blood oxygen (SpO2), a skin temperature sensor, and electrical sensors for ECG heart-rhythm checks and EDA stress readings. Pair that with built-in GPS and you can leave your phone at home for a run and still get an accurate map and pace. The Band 7 measures heart rate and motion with its BioTracker optical sensor and accelerometer, which is enough for steps, sleep, and workouts, but it leans on your phone for GPS distance and skips the advanced heart and stress readings.
Smart Features
The Charge 6 has NFC, so you can pay at the register with a tap and store transit and cards. Neither band has a microphone or speaker, so there are no calls or voice assistant from your wrist on either one. Both show phone notifications. If tap-to-pay and phone-free workouts matter to you, the Charge 6 is the only choice of the two.
Price & Value
The Charge 6 launched at $159.95 and often sells on the street closer to $100 to $130 during sales. The Band 7 launched at $49.99 and frequently dips to around $40. So you are looking at roughly a $50 tracker against a $100-plus tracker. The Band 7 is the better raw value if you only want the basics. The Charge 6 costs more but adds GPS, payments, and medical-grade heart sensors that the Band 7 simply cannot match, which is why most buyers get more for their money by paying up.

The Verdict
The Fitbit Charge 6 is the better tracker for most people. Built-in GPS, ECG, blood oxygen, a skin temperature sensor, and tap-to-pay make it a genuine health and fitness tool, not just a step counter. Buy the Charge 6 if you run or ride and want to leave your phone at home, if you care about heart-rhythm and stress data, or if you want to pay from your wrist.
Buy the Amazfit Band 7 if your budget is tight and you mainly want steps, sleep, heart rate, and workout tracking on a big screen that lasts nearly three weeks per charge. At around $50 it is one of the best cheap bands you can strap on, as long as you accept that you give up GPS, payments, and the advanced heart sensors to get there.
Frequently Asked Questions
Which is better, the Fitbit Charge 6 or the Amazfit Band 7?
The Charge 6 is the better device overall thanks to built-in GPS, ECG, blood oxygen, a temperature sensor, and NFC payments. The Band 7 is the better value at about a third of the price, but it is a basic tracker, not a full health band. Most buyers should choose the Charge 6 unless the price is a dealbreaker.
Does the Amazfit Band 7 have GPS like the Charge 6?
No. The Band 7 has no built-in GPS and relies on your phone’s signal to map distance and pace. The Charge 6 has built-in GPS + GLONASS and can track outdoor workouts on its own with no phone needed.
Is the Fitbit Charge 6 worth three times the price of the Band 7?
For active users, yes. The extra money buys built-in GPS, tap-to-pay, ECG, blood oxygen, and a temperature sensor that the Band 7 does not have. If you only want steps, sleep, and heart rate, the $50 Band 7 covers that and the price gap is harder to justify.
Which lasts longer on a charge?
The Band 7 wins on battery, lasting about 18 days versus about 7 days for the Charge 6. Part of that gap is because the Band 7 has no GPS to drain. The Charge 6 gives up battery life to add features like GPS and NFC.
Do these work with both iPhone and Android?
Yes, both the Charge 6 and the Band 7 pair with iPhone and Android through their companion apps. Fitbit’s app is more polished and has deeper health tools, while Amazfit’s Zepp app is lighter and focused on the basics.
