Battery Performance Query – WHOOP Peak 5.0 (First Charge Cycle)

I recently purchased a WHOOP Peak 5.0 in India and would like to inquire about the battery performance of my device.

I fully charged the device to 100% on 4 July 2026. As of 11 July 2026, the battery level is 45%. This is the first complete charge cycle since I started using the device.

Based on my observation, the estimated battery life appears to be around 12–13 days, whereas the advertised battery life is 14+ days. I understand that the first few charge cycles may require calibration, but I would appreciate your confirmation on whether this battery performance is considered normal.

Could you please advise:

  • Is this battery drain expected during the first charge cycle?
  • Should I continue using the device for a few more charge cycles before evaluating battery health?
