I got my 2600 extended battery two days ago, and am pretty pleased so far. The first day playing with it, after a full night's charge, I went about 12 hours, including playing music, using the GPS, Angry Birds, and being in some low signal situations, and it was at about 10% when I plugged it back in. Not a miracle, but a significant improvement over the original battery's performance. (I have a Touchstone mounted on my dashboard so it doesn't die on me while I'm driving around.)

My problem is that I'm seeing some conflicting information about how to best condition the battery. Is it better to drain it down to 0%, then fully charge it back up, or use it normally through the day, and charge it at night, even if it's not dead yet? And how about ongoing maintenance? Any suggestions appreciated.
