Great article, sa, bookmarked!
The takeaway is to not baby your battery, and I agree.
I used to be a big proponent of bump charging. While that worked, I've gone away from that.
We monitored the Evo 3D when it came out, and immediately freaked that it was charging at too high a voltage. The story was picked up by the blogosphere and concerns grew. That kept up until I found the patent describing the new battery and charging technology that explained our observables.
Many new phones have gone to lithium polymer batteries. Tech changes. What worked on your first Evo doesn't necessarily apply here.
I wish I'd bookmarked the long term graph corresponding to the XDA article that was published here on AF. Once a battery hits the low point as defined by the manufacturer, charging starts again. Over the course of hours, it will look like a sine wave - or, like a roller coaster, up, down, up, down. That's why it's really random where the battery will be when you take it off the charger.
Anymore, maybe it's just best to think of your battery like the staff in the first Indiana Jones movie. One side says, the staff is this big, but the other says, take away some, you gotta pay the dues.
So, following that, you get around 90% (a little over, not much) battery to use.
Because the other side not discussed is the bottom end. You don't want to make a habit of taking your battery to zero, it's ok when you must, but don't make it a habit.
So, it comes off charge truly at 100%, you may hit the charger at say, 9%. It comes off charge truly at 96%, you might hit the charger at 5%.
See what I did there?
You can't escape the dues. If you really want that 4% back when you take it off the charger, take it at the back end.
Battery tinkering accomplishes nothing useful, and if you go overboard, it's dangerous. When you finally fail the system to the point of ignition, the battery will not burn like a little cozy fire. It will burn like a blowtorch. The colorful jet will extend quite a ways and the fumes will be toxic. (I know that folks like to make fun of that, my battery didn't, etc etc. Then again, up to 5 guys can win at Russian Roulette.) I ignited a battery under controlled conditions, on purpose, so I guarantee that's how they go.
Anyway, the battery is what it is. If you want to improve it, leave the charging cycle alone and learn all you can about monitoring what your apps are doing so you don't waste what you do have.
