Also, I keep my phone on the charger when its fully charged for hours on end at times and not once have I ever had it drop 10% after taking off the charger or even after 30 minutes for that matter.

If your evo is left on the charger for several hours after it has finished charging, most users experience the top 10% of their battery (from 100-90%) going within 30 minutes of taking it off the charger.

And you are partially right, I was partially wrong. You SHOULD (as mentioned in a post above) let it like once a month die all the way for calibration. I changed my OP.
