How Long Does The Fitbit Charge 2 Battery Last?

Regarding its battery, the Charge 2 offers a very long runtime without needing to be recharged. On a regular basis, I was able to get between four and five days out of a full charge before I needed to connect it to an outlet. This involves keeping it on throughout the day and using it to keep track of workout sessions at the gym that typically last anywhere from one hour and ninety minutes to two hours.
