Just a reminder: Unlike the NiCd and NiMH batteries used in early cell phones, the currently used LiPo batteries don't like to be fully charged nor fully discharged. The best way to charge them is to let them drain down to about 30% and charge them up to 70% - or 20-80 if that's easier to remember, I guess the percentages aren't stone carved. Anyhow, not totally empty, not entirely full. That can triplicate the number of charging cycles which translate to "from empty to full". On the negative side there'll be much more plug-ins wearing the jack. But if you're careful and insert and remove the plug straight instead of the 45 deg angle most people seem to do the jack should last long enough.
