ONLY an idea, no factual knowledge :) but:
Perhaps the charging circuitry is flipped off when the battery reaches
100% reported charge level, and then the phone is running off of
battery, causing the slow discharge you see? When you unplug and
replug, since the battery is below 100%, the charging circuit is
turned back on till battery level once again reaches 100%? Think this
is the explanation? Have you tried unplugging the phone when it hits
100% batt charge, and leaving it unplugged, and seeing if it maintains
the same rate of discharge?
Are you in a good signal coverage area, or does the phone have to
'shout' to talk with the tower (presuming your GSM is on)? When I'm in
low-signal areas, the battery discharges faster. Been that way for my
Nokia (past) and Motorola (present) phones too.
What about other chipsets - Bluetooth, GPS, WiFi? Are they powered
off, or are they on? Might be contributing to battery drain...
