for some reason my 9650's battery always drops to about 85% within 15-20 minutes after unplugging from a full charge, then begins to deplete at a normal rate. this is my first bb so i'm wondering - is this something i should expect to work itself out soon?
I took mine off the charger at my office at 100%. That was 3 hours ago and it's still at 100%. Making calls on the way home, reading e-mails, and have been on WiFi since being home.

I've noticed that if I remove my phone from the charger the minute it peaks, it depletes the first 10% or so rather fast like you described. If I remove it after an overnight charge, it'll remain at 100% for the first few hours of usage.
I don't know if this phenomenon holds true for this battery/charger combination, but usually when a charger indicates that the battery is charged, it is only charged to about 90-95%. The charger will continue charging at a very low charge rate (trickle charge) until the battery is truly at 100% [or greater] capacity. I never concerned myself with what you described because I attributed it to the phenomenon I described - not knowing for sure whether or not that is truly the case.
Also, if you use your car charger, you're not getting a 'deep' charge and it will deplete faster than if you had used an A/C regulated charger which charges at a much slower rate and imparts what's called a 'deep trickle charge'.

Reason: Phraseology
I have the wifi and sim card both turned off. I have been off charger for about 14 hrs now with calls, constant internet use and texting and am still at 75%. Maybe check if its auto between cdma and gsm? Also if you aren't in wifi area turn that off so it doesn't search?
