I bought my GoPro Hero9 Black about a week ago to use on exploring 4wd journeys in our high country. It's rough country here and no cellphone coverage in much of it so I do not have a smart phone. meaning my GoPro has to function as a standalone camera. My first surprise was to find the battery in the camera dies real quick in not much over an hour. By comparison my old flip-phone battery with camera still lasts 5 days. I had thought from the GoPro advertising I would get several hours out of a battery - enough to walk in some wilderness tracks and capture wildlife. Now I realize they mean the several hours relates to the maximum time you can save on the plugin memory card. It never crossed my mind I would only get an hour out of a battery. I even went to the added expense of a 256gb card so it would last the longest possible time, meaning possibly 20 hours. Before purchase, I had told the store what I was doing and why I was buying it. The salesperson said he was also a 4wd offroad enthusiast and the GoPro would do what I expected. When I took it back the next day after purchase, thinking the battery must be faulty, they checked their material and said they thought I should get at least 16 hours at a 1080p setting (I was running 2.k). They then reset the configuration for the longest time by the lowest settings of 1080p at 30fps. I was not sure about that because I paid almost $1,000 in total including extras and peripherals expecting to get the best quality and now it was on the same settings as my $56 cheap dashcam. I find that if I set it down on a rock to catch wildlife at its 4k best settings , it makes a series of beeps after about 30 minutes, scares everything away, stops recording and is real hot to the touch. The only way I can keep it recording is to have it at the store lowest settings and connect it to the car power by a USB plug to avoid the battery going flat. Initially I left the battery connected as well but it still went flat and I was not sure of it would charge the battery at the same time it was recording. . I read the Hero6 will not but I found nothing concerning the Hero9. This also means I have to leave the battery door open. I was afraid the battery would fall out so for both reasons I removed it and leave only the usb plugged in. I read this recommended for the Hero7 and it works for my 9 also. When I turn the engine off it stops recording and next time I start the car, it repairs the chopped file before resuming a new file all with lots of beeps. Sometimes it will not restart at all but stays off ( like it is dead) with no red light on except the usb plug blue light indicates power is available. It can take up to 2 minutes of pushing buttons testing connections etc before it beeps to turn on again but at other times there is no problem at all. At the times it will not restart, I can put the battery back in and after that it will restart. then I open the camera door again and remove the battery. This is a messy exercise because I have it mounted behind the rear view mirror using the sucker mount and It is not the easiest location to work with if you are high in a mountain pass on loose rocks and gravel while the car is slipping backwards and you have to stop to fix the camera to capture the action. Otherwise it does take great pics. One annoyance is the screen looks OK so you think it's all good but when you download the clips for later editing you find it recorded everything upside down and back to front. The recorded audio is low volume hissy and it probably needs a separate microphone but I understand this is not available for this model. I search for a solution and think there is supposed to be a setting somewhere which makes it save videos the way you see them on its screen but if there is, I can't find it. I read that the Hero7 black has this feature but the Hero7 Silver does not so it must be model-specific and maybe Hero9 Black does not have it? With the store-set 1080p lowest level settings we can save about 9 hours video. I found a report online where someone with a Hero7 Black and a 128gb memory card gets 8 hours max time. I thought with the latest version and double the memory card size plus the 30% improvement that I should get about 20 hours. The store believe maybe 16 hours. But only 9 hours? Isn't there something wrong? The store will not replace it but want to send it away to be checked. I fear they will come back and say there is nothing wrong with it. That's why I need to know if this is just what you expect from a GoPro or is mine not typical? One more thing, every night we have to download the saved video onto an external storage device which takes several hours. At first we thought we had to remove the memory card and bought a card reader but now we found you can use the usb connection to find the files and download them directly. The internal way is much slower but I am worried about overuse of the external option in physically removing the card several times a day to save the files. The internal way often fails and you have to keep a watch on progress. About GoPro as an action camera? Yesterday by coincidence, we came upon a remote beach surf rescue with a radio controlled flotation device sent out to the scene because the surf was too violent for swimmers. I thought it would be a perfect opportunity for the action camera but first we had to remove it from the vehicle and then install the battery by which time we had missed the launch and then wanting to follow it out to sea, discovered the Hero Black 09 does not have a zoom capability depending on the settings, and by the time we tried all the settings to find it has a max of only 2x zoom we had missed the rescue. At that moment for the first time, I actually regretted buying the GoPro Hero9 Black and wondered what it was doing for me that my old JVC didn't do. Thinking of dashcams, the GoPro advertises that it will do "looping" and it specifically references like a dashcam. But when you get into it, you find this is not the case at all and it is possibly creative advertising. Any standard dashcam saves video in sequential time slices until the card is full at which time it deletes the oldest saved file and records the current new one using that deleted space. The Gopro operation appears quite different. It requires you to preset a fixed duration file which it continually overwrites so you do not have any record of history beyond the single file. When I first spotted that, I believed it must be a typo by GoPro but apparently not. That caught me out because I thought it really would operate as a dashcam.. At this time we are looking to see if we can change our operating practices and expectations to accommodate the way GoPro does things as it does take nice pics and clips with best settings. I am not the brightest at this technology, I just wanted to buy a simple to use quality camera for recording our adventures. ???
