I know, there is no "memory" effect to lithium-ion batteries, but even these need to be totally emptied to extend their life from time to time. That is what I want to do.

Due to the fact that I have to plug my 650 to a USB hub every one or two days, the accu will never be totally emptied. Far from that. No good!

So I want USB charging to be switched off. I know that it can be done, my WinMo smartphone can be adjusted not to be charged.

Yep, the 650 doesn't have an OS like WinMo, but my PC does, so it should be possible to solve the problem the other way round by unswitching the charging function on my PC.

And, I am sure, there is a way to switch it off on the 650, you only have to dig deep into the firmware.

I didn't! Did you?

Or do you know a solution to stop charging from the PCs side?
