I did manage almost 3 weeks of 2 hours or more per day of reading (finally had to charge it Saturday, which makes 19 1/2 days w/ 30-40hrs of reading time total, maybe a little more), so I feel like the battery life was not too bad. It was annoying that once the battery charge indicated dipped below 50% it would occasionally (about once per day) power itself off when first waking from sleep, allow itself to be powered right back on and then would report 8-18% charge for a minute or two and then 40 odd percent. It finally turned off and refused to power back on even after waiting 5 minutes one of those times when it first said 8% charge, refused to read a higher charge and I got about 6-7 pages in to reading when waking up from sleep. So I semi-suspect once the indicated charge dropped below 50%, the times it was telling me 40 odd percent was innacurately high. Though when it was reading 50% and above it might have been inaccurately high.

I just don't know.

At any rate, as my other thread mentioned, it took 10-15 minutes plugged in to my computer and a further 1:45hrs plugged in to the wall adapter to bring it to 100% charge (which I think is about right charging from 0%????). I didn't really use it that day or the next until that evening. It read 98% charge over the 36hrs since I charged it to full and let it sleep (I did reboot immediately after the full charge). I hooked it up to my computer to "test" topping it off. It took somewhere around 10 minutes or maybe a little less to top it off and as of post-breakfast 15-25 minutes of reading (a little last night right before bed and a little during breakfast) it said 99% full.

Right before topping off, waking it it gave me an 8% warning for a few seconds and then immediately reported 98% charge in the settings menu. sigh....

Hopefully I can at least get a handle on its behavior. I don't mind the occasional innacurate battery read, or even power off needing to turn it right back on because of some fault battery sensor or something going on. I just want my 2+ weeks of heavy use and reliable ways to keep it working until I HAVE to charge it.

After the next 1-2 battery cycles I plan on charging it "frequently" which probably means about once a week or so. I just want to know that I have the battery life there if I need it.
