| Exact variant | Black, nylon strap with hook-and-loop closure for 145 to 205 mm wrists | Three finishes (Coral/Champagne Gold, Porcelain/Silver, Obsidian/Black aluminum), with small and large Infinity bands in the box |
| Dimensions | Amazfit lists the tracker at 33.97 x 24.3 x 10.59 mm without the sensor, and 20 g. TechRadar's review gives 20 g with the band. The nylon strap is 22 mm wide and fits wrists from 145 to 205 mm around. The body is fiber-reinforced polymer. | The tracker is 36.73 mm long, 23.09 mm wide and 11.20 mm high (1.45 x 0.91 x 0.44 in). Google lists 30 g without saying whether that includes the band. The small band fits wrists from 5.1 to 6.7 in around, and the large fits 6.7 to 8.3 in. Both come in the box. |
| Installation | No installation. You pair it with the free Zepp app on an iPhone running iOS 15.0 or later or an Android phone running 7.0 or later. In the box are the strap with the tracker fitted, a magnetic charging head and a manual. Amazfit says the USB-C charging cable isn't included. The packing list has no armband, and Amazfit lists a Helio Armband as a separate accessory. | No installation. You need a smartphone, a Google Account and the Google Health app, on iOS 16.4 or later or Android 11 or later. It syncs over Bluetooth LE at up to 30 ft and needs an internet connection. In the box are the tracker, small and large Infinity bands and a charging cable. Google's Charge 6 guide says the battery isn't replaceable. |
| Materials | The body is fiber-reinforced polymer, and the strap is nylon with a hook-and-loop closure. TechRadar's review describes the central part as plastic with no metal and says it doesn't feel premium. | The display is AMOLED under Corning Gorilla Glass 3, and the finishes are listed as aluminum. The Infinity band is flexible silicone with a loop and peg closure. Google advises drying the band after it gets wet or sweaty and taking the band off now and then to rest your wrist. |
| Warranty | One year from the date of original purchase, per Amazfit's US warranty policy. It covers products bought from Amazfit's official US online store, not other sellers. Amazfit repairs or replaces the device at its option, or may refund the purchase price, and you pay to ship it to Amazfit. A repaired or replaced device is covered for the rest of the year or 90 days, whichever is longer. The warranty excludes normal wear and tear, misuse, accidents and use for medical, healthcare or treatment purposes. | Google doesn't publish a Charge 6 warranty length. It points owners to its Hardware Warranty Center, which lists Fitbit hardware bought on or after July 11, 2023. Google's older Fitbit Limited Warranty covers devices bought before that date. It gives one year for new products and excludes cosmetic damage, accidents, normal wear and consumables such as batteries. Google's Charge 6 guide says liquid damage voids the warranty. |
| Returns | 30 days from the purchase date to request a full refund, with a return authorization from Amazfit. Request the authorization by email or phone within the 30 days, then send the product back in the same condition, with all accessories and original packaging, at your own shipping cost. Amazfit can refuse a return that arrives without an authorization or all parts, or charge a 15% restocking fee or the value of missing accessories, whichever is higher. Orders placed in November and December can be returned through Jan 31 or for 45 days, whichever is longer. Shipping, handling and taxes aren't refundable, and refunds are paid within 4 weeks of Amazfit receiving the product. | 15 days from the day you receive it, for most items bought from the Google Store. Back up and factory reset the tracker first, then send it back in its original box with all accessories and documentation for a refund. The included Google Health Premium trial is canceled with a return. Google's help page doesn't say who pays return shipping and doesn't mention restocking fees. |
