I keep reading posts about "conditioning" the battery by draining it to empty, charge, rinse and repeat to get better use of the battery. Is there any quick and/or easy way/app to drain the battery?
No, that's fine. Lithium Ion batteries can pretty much take whatever you do to them and not be affected significantly. There is one thing that they do not like though - and that is a complete drain (it can damage the cells). 5% is fine, but 0% is very bad. The only reason to drain it purposefully is to help the battery meter stay correctly calibrated. Let it go down to 15% or less every now and again just to keep it calibrated.So is it bad to keep it plugged in most of the day? While at work, I stream pandora/slacker and keep it plugged in via USB ... is this a bad thing to be doing?
Lithium batteries do not have memories and require no conditioning. Just plug it in and charge it. Its ready to go charge it as often as you like.
