|
| Exact variant | Three finishes (Coral/Champagne Gold, Porcelain/Silver, Obsidian/Black aluminum), with small and large Infinity bands in the box | Night Black with the SoftWeave Textile band (S–L) |
| Dimensions | 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. | Polar lists Loop at 1.1 in wide, 1.7 in high and 0.4 in thick. It weighs 1 oz with the band and 0.7 oz without. Polar's size chart says the package includes two bands. The S/M fits 135–190 mm wrists and the M/L fits 160–230 mm. |
| Installation | 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. | No installation. You set it up with the Polar Flow app, and Polar's page gives no minimum phone or operating system versions. The box holds the Loop, the SoftWeave bands, a buckle and a Polar Charge 2.0 cable, which is proprietary USB-C. Polar's package list doesn't include a power adapter. |
| Materials | 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. | Polar lists a stainless steel case and bezel. The band is SoftWeave textile in Night Black. Polar doesn't say what the textile is made of. |
| Warranty | 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. | Polar gives a two-year guarantee on the device, but not on the SoftWeave bands. Polar Electro, Inc. issues it for products sold in the US and Canada, covers the original buyer against defects, and asks for the receipt as proof of purchase. Silicone or plastic wristbands get one year, and textile and leather wristbands aren't covered. Normal battery wear, accidents, misuse and cracked or scratched cases are excluded. Polar's returns page says battery replacement is covered for the first six months, and Polar repairs or replaces covered products. |
| Returns | 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. | Polar's online store takes returns within 30 days, and damaged or defective items within 30 days of purchase. Items must be unused, in good condition and in the original packaging. You send them with a completed return form and a copy of the packing slip. Shipping costs are refunded only for damaged or defective products. The policy doesn't mention a restocking fee or say how long refunds take, and it doesn't say whether a standard return counts from purchase or delivery. |
