I have my information from German c't magazine. But I found an  
English source that also provides some experimental data on battery  
aging:

Note figure one on this page:
<http://www.batteryuniversity.com/parttwo-34.htm>
> The speed by which lithium-ion ages is governed by temperature and  
> state-of-charge.

So, as I said before, yes, the cycles are an issue. But from what I  
read and (sadly) personal experience, the permanent charging stresses  
the battery more. )c:
