A:Answer Hi Nancy, thank you for reaching out to us. The battery life of the camera depends on many factors, like if you are capturing pictures or videos, if you are using audio, or capturing sound, using the flash, the resolution set etc. This camera needs to be charged for around 3-4 hours for a full charge. You should be able to run it for a day, unless it there is extreme usage. Please reach out to us at 18774080033 or support@sakar.com quoting ticket number 41739, if you have any more questions. Thank you.
