When I bought my GoPro I went ahead and bought an extra battery from Best Buy for $19.99. I think it would be a great idea if you plan to use your GoPro quite a bit to always have an extra battery handy. In order to charge your battery you have to take your GoPro out of the case, on the side there is a battery compartment, take the cover off of that and you plug in the USB cable then put the other end in your computer or you can use an adapter like you might for your smartphone and plug it in to an electrical socket. This will charge your battery and the light will flash red until it is fully charged. To charge your extra battery open the battery compartment, take the original battery out, put your extra battery in and close the compartment. Plug it back into your computer or adapter and charge that battery.
When I first purchased my GoPro I had planned to take videos of my kids playing lazer tag at my oldest son’s birthday party so I got it all charged up and ready to go. I spent some time getting the GoPro app downloaded onto my phone and connected to the camera via WiFi so I could see on my phone what was being video taped while we were running around playing lazer tag.
Well sadly I messed up and didn’t get the lazer tag video because I hadn’t used the camera yet, I had let it sit on my desk for two days before the birthday party, I didn’t bring the extra battery that I had charged and although I turned off the WiFi app on the phone I did not turn off the WiFi on the camera. The camera battery is supposed to last about two hours according to the GoPro website’s comparison chart or an hour and a half if it’s on WiFi and you’re using the app. It probably lasted on my desk for about that hour and a half and by the time we got to the skating rink to play lazer tag it was dead and I hadn’t brought the extra battery. Like most things I learn the hard way, that won’t happen to me again, I will always bring the extra battery and I will be checking to be sure it is charged before I leave the house!
