Hi, I started to have problem with my Phantom 3 Standard . After taking off , drone goes to I would say 50 feet high and give me the " Critically Low Voltage " warning and landed.I tried with extra battery what was fully charged and was the same result. Any idea ? Kind of annoying .....

If you're sure the battery was 100% charged, then the only thing that comes to mind is a cold battery. Was it real cold out when this happened?

Hello milosusa, may I know your flight environment, such as temperature, please check the screen shot about the details.
Then please full-discharge it and then charge it again, turn them on, then check the battery info on the APP.

Thanks for response, but temperature was over 70°F....
