The Apple battery charging guide is an excellent resource for learning how to get the longest life from your battery. I have followed their suggestions for years on this and certainly do understand the physics behind it. I was simply commenting here because I was surprised that the battery life was half the advertized after only a few cycles.
@rkomar: certainly it's premature to declare that the battery has issues, which is why I started this thread: To see how other PRS350 owners were faring. I'd also like to know if the PRS650 is any better... so far no actual users have replied.
@Xanthe: Many devices like the Sony and the Kindle state the battery life in terms of page turns. I do use the smallest font, always. I average about 400 words per page. My girlfriend uses her Kindle in the opposite way, averaging about 140 words per page, it has a much larger battery too.

Ibought my 650 in mid september.
I have recharged it twice, mainly to test the third party charger I bought two days ago and to see how long it took to recharge from a USB port on my computer.
Both times the battery was still 75% full according to the battery meter.
I have found that the battery seems to discharge quicker if I let the reader go into standby mode rather than power it off when not using it.
But I haven't come anywhere near fully discharging it.
I use (read) it 3-5 hours a day since buying it, have 300+ books loaded on a 4GB SD card, and have the font set at the default size.
