Amazfit Bip 6 Review: Fourteen Days, on Amazfit’s Settings

Amazfit rates the Bip 6 at up to 14 days of typical use, 6 days of heavy use and 26 days in battery saver mode, from a 340 mAh cell. The footnotes on Amazfit's product page spell out what typical means: a heart-rate reading every ten minutes, a static watch face, five minutes of screen time and 150 notifications a day, and three 30-minute GPS workouts a week. Heavy use switches heart rate to every minute, adds stress and sleep-breathing monitoring and triples the screen time.

Tom's Guide lost about half the charge in six days, which points to roughly twelve. Android Authority ran the always-on display while tracking GPS workouts and sleep, and the watch used about 16% a day, a little over six days, right on Amazfit's heavy-use figure. Turn the always-on display off and the second week comes back.

Charging uses a magnetic puck that plugs into any USB-C cord, which Android Authority welcomed, and there is no cable in the box. The puck differs from the Bip 5's, so an old charger will not fit. Amazfit also notes that the screen's 2,000-nit peak is unavailable once the battery drops below 30%.

Against an Apple Watch on the same workout, Android Authority found the Bip 6's heart rate within about five beats throughout. Its GPS track put the runner on the wrong side of the road at one point, yet total distances across several runs nearly matched the Apple Watch, and the watch locked on to satellites within seconds. Tom's Guide saw a two-minute wait while the watch connected to the phone before GPS was ready, which points to the assisted-GPS data the phone supplies.

Compared with a Pixel Watch 3, the Bip 6 overestimated core sleep by 30 minutes or more in Android Authority's nights, and a short wake-up ended the night, so the rest was logged as a nap. Tom's Guide found its sleep stages close to an Oura Ring's, though not identical.

Offline maps are free, with limits Amazfit states in its notes. You import OpenStreetMap files and a route file, and you cannot pick a point on the map and navigate to it. Without a downloaded map, Tom's Guide saw only an arrow and a line on a blank screen. Turn-by-turn voice prompts come in English and Chinese.

Android 7.0 and iOS 14.0 or later both work through the Zepp app. The two phones do not get the same watch, though. Amazfit's footnotes reserve WhatsApp speech-to-text replies and picture messages for Android, and Tom's Guide, testing with an iPhone, could read messages but not answer them. Health data goes to Apple Health or Google Fit, depending on the phone. Streaming music cannot be controlled from the watch in Tom's Guide's experience, though music saved to the watch plays through Bluetooth headphones.

The free app shows daily sleep and readiness scores and weekly and monthly trends. Personalized sleep and stress advice from Zepp's wellness assistant needs the Zepp Aura subscription, an annual fee that Tom's Guide notes works out close to Oura's, whose membership is required for scores and trends. Some watch faces are paid. Amazfit's US warranty runs one year.

The watch weighs 27.9 g without the strap and is rated 5 ATM for swimming. Tom's Guide found it comfortable for long wear, though the case occasionally knocked against the wrist on runs, and the Black model looked navy to its tester.
