What is true of this model and changes how you fix it
- Model — Inspire 3 (basic tracker)An entry fitness band for steps, heart rate and sleep. It has NO built-in GPS (it uses your phone's GPS — 'connected GPS'), NO ECG, and NO microphone/speaker or cellular. So GPS-accuracy issues depend on carrying the phone, and voice/cellular/ECG symptoms do not apply.
- Connected GPS onlyFor mapped/outdoor workouts it relies on the phone's GPS, so you must carry the phone for distance/route accuracy — without the phone, distance is estimated from motion, which is less accurate.
- Long batteryBecause it is simple (no onboard GPS, no bright screen driving), battery lasts up to ~10 days — a short runtime is unusual and worth checking against always-on settings.
- What owners run intoThe main reports are tracking that does not sync, a tracker that will not charge or a screen that stays dark, and notifications that do not arrive. Most syncing problems trace to Bluetooth, app permissions or battery saver on the phone.
- How to approach a faultPull to sync in the app, check Bluetooth and permissions, restart the tracker and the phone, and remove a stale Bluetooth entry. Charge the tracker before judging.
- Straps and skinA strap that is too tight or wet causes poor heart-rate readings and skin irritation. Wash and dry the band and the tracker's back.
- Account and historyHistory lives in your Fitbit account, so changing phone does not lose it. Sign in and set the tracker up again.

Exact questions
Questions that only have an answer for the Fitbit Inspire 3
My Fitbit Inspire 3 running distance is inaccurate.+
The Inspire 3 has no built-in GPS — it uses your phone's GPS (connected GPS), so for accurate outdoor distance and route you must carry your phone with you and keep the Fitbit app permitted to use location. Without the phone, it estimates distance from your arm motion and stride, which is far less accurate. So carry the phone for GPS workouts; the band itself cannot track location on its own.
How long does the Inspire 3 battery last?+
About ten days.
Will I lose data if I change phone?+
No, it is in your account.
Why is the screen dark?+
It may be flat; charge it.
Does it sync over Wi-Fi?+
No, over Bluetooth.
