Here's a list of the average run times for the HERO3 cameras with a fully charged battery*.  

 Avg. time for camera onlyAvg. time for lowest power consumption settingAvg. time for highest power consumption settingAvg. time for Camera + LCD Touch BacPacAvg. time for Camera + Battery BacPac2
Black Edition 1.5 hrs 1.5 hrs (1080-30) 1 hr (WVGA-240) 1 hr 2.5 hrs
Silver Edition 2 hrs 2 hrs (720-30) 1.5 hrs (WVGA-120) 1.5 hrs 3 hrs
White Edition 2.5 hrs 3 hrs (WVGA-60 and 720-30) 2 hrs (1080-30) 1.5 hrs 3.5 hrs
Please note there are a variety of conditions that can affect run times, such as:
  • Cold weather, which will reduce battery-life.
  • Enabling Wi-Fi, which will reduce battery-life
  • The above times are based on doing a continuous record.  Stopping/starting recording, or powering camera on/off repeatedly will reduce the total record time.
*Based on GoPro engineering testing. Actual performance may vary based on settings, environmental conditions and other factors. Maximum battery capacity will normally decrease with time and use.
