The 3.0 Strap uses Bluetooth Low Energy (BLE) to transfer data from the Strap to your mobile phone. An important difference from previous generations of WHOOP is that the WHOOP app will need to stay open in the background to continue transferring data and being caught up.
The main factors that contribute to data backlog include:
- Battery Optimization Settings:
*In addition to the factors below, different Android devices abide by different battery optimization settings which can significantly limit background activity and Bluetooth activity. For specific phone settings, please refer to the link HERE.*
- Airplane mode
- Being Out of Bluetooth Range
- Power Saving Mode
- Force Quitting the App:
If you are “swiping up” or on the app to terminate it, you are indicating to the operating system that you, as the user, no longer wish the app to continue running.
- Dead WHOOP Strap:
You can double-tap the face of the WHOOP Strap to check the battery life
How long will it take for my data to catch up?
The WHOOP Strap is able to hold up to three days of data. If the data sync from the Strap to the phone falls behind, once reconnected it will start syncing your data, in order from the oldest to the most recent. Syncing a full day of data (24 hours) takes approximately 45 minutes.
