With a fresh battery and fresh SD card the camera will shut off moments after starting to record a video and say "charge the battery" I turn it back on and the battery is full.
This is such a frustrating issue and I dont want to spend hundreds to send it to cannon when the fix might be simple.
Well then that's not good news. I cannot think of a setting in the menus that would cause that. Does it take pictures ok and the battery lasts as expected?
An internal problem will be expensive to repair and my guess is Canon might offer you a refurbished one instead of the cost of a repair. Im sorry I do not have a simple fix for you perhaps someone else might have an idea
