I have owned sgs1, sgs2, sgs3 and sgs4. And I have never had any problems with the battery getting damaged because of overcharging, it stops charging at 100%, like it should be.
It shouldn't stop at 93%?. To me that's not a good thing at all. And that I have to remember to unplug it, and plug in the charger again to get the last 7% on the battery, ain't a good thing either.

My earlier comment about bad timing, what it meant was that maybe you have just been unlucky and have pulled the phone off when it was no longer near 100. Bad timing.
I haven't charged my phone to 100 for a while, so I can't really report on the behaviour of my phone, but the battery in the phone is fairly advanced compared to the average battery. I would expect that it may even have some life-extension features that removable batteries lack. These features, not problems, will be trying to limit stress to your battery ie. trying to keep the battery away from "100%". But if you continue to have problems getting it close to 100, maybe the calibration really is off.
I would discharge all the way until the phone shuts off. You say you haven't done that because you don't want to damage the battery, but "0%" isn't actually 0%. You will stress the battery, like you would by charging to "100%", but you won't damage it. Really that is the one clear option I see that is left in regards to your question.
Or... Don't charge your phone so high. The battery is good enough to last on less than "100%". Your battery will like you for it. It'll extend it's lifetime.
