The Band's battery normally lasts about two days, so it’s recommended that you charge the Microsoft Band during periods when it is turned off, or when it is not in use. Charging the Band in the car on the way to work, or at home while cooking or taking a shower could work. The batteries should reach nearly 80% charge within 30 minutes of charging, and a full charge in approximately 90 minutes. If your Band isn't lasting that long, try the tips on the Troubleshooting Page.

The Microsoft Band's battery should provide two full days of use, including exercise and sleep tracking. Depending on how you use the Microsoft Band, battery life may be shorter or longer. Visit our Troubleshooting Page for more information on battery life and charging. If the troubleshooting doesn't solve your problem, visit the Battery Replacement Guide to replace the battery for new ones.
