That is one golden observation. Thats the first time i've heard of such thing. Makes me question a lot of things.
If the charge can drop so much it's observable, can it indicate a unreliable power component/circuit?
Is it really a charge (why would there be such thing), or a way that half dead SDM behaves?
Etc...

It doesnt matters. If the've detected the problem, they should recall and replace lenses in shops instead of smuggling them to buyers. If they still allow bad lenses to be sold, they have not fixed the problem.
P.S. And i'm still avoiding any SDM lenses until the problem is rectified (explanation and proof of fix, extended warranty*, SDM II, DC or similar way).
* - few have written that the SDM fails just after the warranty ends.
