I have learned that the auto-power-off can be turned off (via app). Still the latter question remains: are the four hours of battery life in reference to constant read/write access or in reference to simply being turned on? (or is the battery life four hours regardless of read/write access)
For example, let’s say I use the drive as a USB device on a PC and save a file onto it. So that I can access the file later wirelessly without physically pressing the button on the drive, I turn on the drive right then. I leave the drive turned on but not connected to anything until five hours later, when I attempt to connect to the drive. Will the drive be out of battery power or still be functioning?
