Help CenterThere are three different power-saving modes you can choose from on your camera: auto, on, and off. Based on your description, it sounds like the power saving has been deactivated(off) so the camera would just keep running and using up the power while standing by, so it might not be able to last through 24 hours without needing to be charged again.
Typically, we would advise customers to turn the power-saving mode on(choose “on” or “auto” in settings) to conserve battery life during longer shoots by allowing the camera to sleep when not in use. So, I would suggest giving it another go with the power-saving mode enabled.
Here’s the difference between the option “auto” and “on”. If you have the power saving set to “on”, it will still go into sleep mode even if it's connected to a power source. If you choose “auto”, your camera will stay online when it's plugged in. When you find yourself in a tough spot, with only one power bank as your power source, "on" will be your best bet. It helps conserve your battery life as much as possible. On the other hand, if you have access to a continuous power source and can keep your camera plugged in, "auto" is the way to go. It’s always good to keep your camera online, it can make things a lot easier and save you from any potential connectivity issues. Plus, you'll be able to access your camera conveniently whenever your phone is nearby. However, keeping it online is quite power-consuming if I’m being honest.
In conclusion, if the battery is fully charged and the power-saving mode is set to “auto”, then I think the camera can easily survive the standby mode and complete the recording without any issues.
