Side-by-Side Comparison
| Spec | Fitbit Charge 6 (2023) | Xiaomi Smart Band 10 (2025, Global Version) |
|---|---|---|
| Price | $159.95 | $51.99 |
| Release Year | 2023 | 2025 |
| GPS | Built-in GPS + GLONASS — works with the phone left at home | None — no GPS chip. Xiaomi's own spec sheet does not list GNSS; outdoor distance depends on the phone |
| Display | AMOLED colour touchscreen under Gorilla Glass 3, with optional always-on mode | 1.72-inch AMOLED touchscreen, 1500 nits high-brightness mode |
| Rated Battery Life ( days) | 7 | 21✓ |
| What the Battery Claim Assumes | Google's 'up to 7 days' assumes the always-on display OFF and SpO2 off; the spec sheet states both 'will require more frequent charging'. Full charge takes ~2 hours | Xiaomi publishes three figures: 21 days typical, 9 days with the always-on display, 8 days under heavy load. The 21-day headline assumes AOD off |
| Subscription Model | Optional in name, heavy in practice — Daily Readiness Score, the Sleep Score breakdown, the detailed Stress Management breakdown and the workout library all sit behind Google Health Premium. 3 months included | None — no paid tier exists for the Mi Fitness app |
| Annual Subscription Cost ($) | 99.99 | 0✓ |
| Water Resistance | 5 ATM / 50 m to ISO 22810:2010 — Google notes water resistance 'decreases or is lost over time' | 5 ATM / 50 m to ISO 22810; Xiaomi explicitly excludes hot showers and saunas |
| ECG / AFib & FDA Status | 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 | No ECG hardware and no AFib detection |
| SpO2 Sensor | Yes — red and infrared sensors, overnight SpO2 | Yes — blood oxygen and stress via the nine-axis sensor package |
| Phone Compatibility | iOS 16.4+ or Android 11+, and setup requires a Google account | iOS and Android via Mi Fitness, but US units are 'Global Version' grey imports with no US Xiaomi warranty channel |
| Charger | 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) | Proprietary magnetic pogo-pin charger |
| Data Export | Google Takeout export of the Google Health/Fitbit archive (JSON and CSV bundles) | Not documented by Xiaomi — Mi Fitness syncs to Strava and Apple Health/Google Fit, but there is no published bulk export |
| Warranty | 12 months | 12 months |
| Colors | Obsidian / Black Aluminum, Porcelain / Silver Aluminum, Coral / Champagne Gold Aluminum | Midnight Black, Glacier Silver, Mystic Rose |

Pros & Cons
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
Xiaomi Smart Band 10 (2025, Global Version)
Pros
- +Three weeks of battery and a 1500-nit AMOLED for around $52
- +Genuinely nothing is paywalled — no premium tier exists at all
- +5 ATM and 15.95g make it the easiest band here to forget you are wearing
- +Huge choice of first-party straps including ceramic, leather and metal
Cons
- −No GPS chip at all — Xiaomi does not even list GNSS on the spec sheet, so every outdoor distance is the phone's
- −US buyers get 'Global Version' imports; there is no US Xiaomi warranty or support channel behind them
- −The 21-day figure drops to 9 days the moment you turn on the always-on display
- −No documented way to bulk-export your own data out of Mi Fitness
- −Sleep and recovery analysis is shallow compared with Garmin, Polar or WHOOP
