Hey @gitup what should the trickle charge be for F1?
I see almost 300mA which concerns me. It seems too high, and F1 and the battery are really worm. Normally, I see devices using 10-50mA trickle current (after full charge) - 300mA seems too high.

Maybe other parts of the camera are kept powered too in such a scenario ?
Could also be a result of the charge circuitry used. ??

Here is a fully charged phone (with a much larger battery) trickle current ~40mA.

That is normal, the Amberella based cameras always use a lot of power to do nothing! Cameras with Novatek processors are better, but still can't turn everything off when not in use so still take more than a phone.

Not sure why it can't shut itself down or go to sleep when it is full in charge mode though...

Finally had time to check with my other Ambarella (A12) camera:

Zero (or close to it) when charged. Maybe Garmin knows a secret...
