Because if I plug it in overnight, wake up in the morning and it says 100%. Unplug it and plug it back in, symbol says charging again and it takes about 10-15 minutes to say 100%.
If I plug it in when I am at work and as soon as it hits 100%, I unplug it. Plug it back in and it says charging but only for about 5 seconds then it says 100%.

It does stop charging at 100%, but it monitors the battery voltage. When the voltage drops a bit too low, it applies a low charge again, 5v and maybe 200-300 mah.
Oddly enough, it doesn't match the calculated discharge with additional charge. So while using the phone while it's plugged in, you're running off the battery, till it decides the charge dropped a little too low, then it adds some amperage as appropriate.
Also, that's a big part of the reason you'll see it say 100% battery, but then it will still take a while for the charge indicator to stop. It'll hit 4.2 volts at 900mah, so it "stops charging"... as soon as it does that, the voltage drops, so it adds a 400 mah charge again, and the voltage will continue to creep up a little bit.
