Full ECG, electrodermal activity stress sensing, SpO2, and continuous heart rate in a tracker thinner than most smartwatches.
Google Maps navigation, Google Wallet NFC payments, and YouTube Music controls — more useful on-device apps than any previous Charge.
7 days of typical use, dropping to around 30 minutes per GPS workout session before needing a charge.
The dual-engine Snapdragon W5 + BES2800 co-processor architecture delivers up to 5 days in Smart Mode — 2–3× longer than most Wear OS rivals. A 10-minute charge provides a full day of use.
L1 + L5 dual-band GPS gives running and cycling route accuracy typically found only on $500+ sports watches — accurate to within metres even in urban canyons.
Google Maps turn-by-turn navigation, Google Wallet contactless payment, and Play Store app access — plus Google Health Connect integration for the full Android wearables ecosystem.
The right pick depends on what you optimize for.
