Just curious about how these batteries charge and what's the best way to wear them down. In other words, I know there are some batteries that, once you plug them in to charge, they drain the battery and then begin a full charge with the battery being low. Others, and it may be the charger itself, idk, but they seem to charge from where the battery is at currently, meaning if it has a 40% charge, it will just start the charging process from 41% on and so on. From what I can see, it looks like the batteries begin to charge up from whatever % it's currently at, but is this the best way for these batteries to last? Sure it may work, but how much long term life are we taking from them, if this is the case? Right now, I have 1 standard battery and 1 extended. I haven't had the phone that long, so I keep playing with it (giggles), so I'm wearing the extended battery down fairly quickly. I expect that with the amount of use it's getting. If I'm in my work truck all day, and I leave it on the cigarette lighter charger all day, am I making the battery weaker by giving it a constant charge? With my Droid X, I just had the regular battery and when I kept it on the charger, it seemed that when I had it off the charger, the phone seemed to die quicker. Am I making any sense yet, because I'm starting to confuse myself lol.
