well, the battery, when I removed the diode, was rather low: not only I didn’t manage to get more tha 5 minutes of operation in any way, but if I remember well before removing D3 I had just tested again the battery life, depleting it completely (and obtaining 5 minutes of operation)…
then obviously I disconnected the battery, removed the diode, reconnected it, and connected the dso to an usb port, hoping to get a nice “battery full” icon!
unfortunately, no way… 5 minutes again
