Side-by-Side Comparison
| Spec | Amazfit Bip 6 (2025) | Fitbit Charge 6 (2023) |
|---|---|---|
| Price | $79.99 | $159.95 |
| Release Year | 2025 | 2023 |
| GPS | Built-in GNSS across five satellite systems, with free offline maps — no phone required for route or pace | Built-in GPS + GLONASS — works with the phone left at home |
| Display | 1.97-inch AMOLED touchscreen | AMOLED colour touchscreen under Gorilla Glass 3, with optional always-on mode |
| Rated Battery Life ( days) | 14✓ | 7 |
| What the Battery Claim Assumes | Amazfit's 14 days is 'typical use'; battery-saver mode stretches to 26 days. Continuous GPS use and the always-on display are not covered by the 14-day figure. Full charge 1.5–2.5 hours | Google's 'up to 7 days' assumes the always-on display OFF and SpO2 off; the spec sheet states both 'will require more frequent charging'. Full charge takes ~2 hours |
| Subscription Model | None — every metric and the offline maps are free | Optional in name, heavy in practice — Daily Readiness Score, the Sleep Score breakdown, the detailed Stress Management breakdown and the workout library all sit behind Google Health Premium. 3 months included |
| Annual Subscription Cost ($) | 0✓ | 99.99 |
| Water Resistance | 5 ATM / 50 m for up to 10 minutes | 5 ATM / 50 m to ISO 22810:2010 — Google notes water resistance 'decreases or is lost over time' |
| ECG / AFib & FDA Status | No ECG hardware and no AFib detection | ECG app via multipurpose electrical sensors plus PPG irregular-rhythm notifications. Fitbit's ECG feature is FDA-cleared in the US; Google's current Charge 6 spec sheet does not restate the clearance |
| SpO2 Sensor | Yes — blood oxygen plus stress and sleep via BioTracker | Yes — red and infrared sensors, overnight SpO2 |
| Phone Compatibility | iOS and Android via the Zepp app (text reply is Android-only) | iOS 16.4+ or Android 11+, and setup requires a Google account |
| Charger | Proprietary magnetic charging cradle terminating in USB-C. Amazfit's US product page states a cable is not included as a sustainability measure — confirm box contents before buying | Proprietary magnetic cable shared with Charge 5 and Luxe; Google sells it as a standalone accessory (the Google Store listing did not render a price when checked) |
| Data Export | Zepp syncs to Strava, Google Fit and Apple Health; no documented bulk-export format | Google Takeout export of the Google Health/Fitbit archive (JSON and CSV bundles) |
| Warranty | 12 months | 12 months |
| Colors | Black, Stone, Red | Obsidian / Black Aluminum, Porcelain / Silver Aluminum, Coral / Champagne Gold Aluminum |

Pros & Cons
Amazfit Bip 6 (2025)
Pros
- +Real multi-band GNSS and offline maps for $79.99 — half the price of the cheapest Fitbit with a GPS chip
- +14-day typical battery with a 1.97-inch AMOLED is a combination nothing else here matches
- +Standard 22mm quick-release straps, so replacements are a few dollars rather than $35
- +No subscription, no gated metrics, works with both iPhone and Android
Cons
- −Amazfit's US page says no charging cable is included in the box — verify before you buy, because the cradle is proprietary
- −No ECG, no AFib detection and no FDA-cleared health feature of any kind
- −Zepp's recovery and sleep modelling is shallower than Garmin's or WHOOP's, and there is no documented bulk data export
- −Sits awkwardly between band and watch — it is 46mm, so it wears like a watch not a slim tracker
- −The 14-day claim does not survive regular GPS workouts or the always-on display
Fitbit Charge 6 (2023)
Pros
- +Genuine built-in GPS — the single spec that separates it from every other Fitbit band
- +Bluetooth heart-rate broadcast to treadmills, bikes and Peloton is rare at this price
- +Both S and L bands ship in the box rather than being a $30 upsell
- +ECG and EDA electrodes give it health hardware the cheaper bands physically lack
Cons
- −Daily Readiness Score and the useful half of the sleep analysis are Google Health Premium features — $99.99/year once the 3-month trial lapses, up from Fitbit Premium's old $79.99
- −The 7-day figure assumes always-on display and SpO2 both off; turn either on and Google itself says to expect less
- −A Google account is mandatory to set the tracker up at all
- −Proprietary charging cable that fits only Charge 5, Charge 6 and Luxe
- −Wrist optical HR degrades badly above ~150bpm — peer-reviewed testing found Fitbit units underestimate HR during intense intervals
