Battery Charging
I bought my PRS300 in October and fully charged it then. I never let it hit the low battery warning and would just top it up every two weeks or so. In January I decided to see exactly how long a charge would last and how accurate the battery meter was. I realize that to properly calibrate the meter you should run a few charge/discharge cycles so my meter is currently not very accurate.
I fully charged it on Sunday, Jan 17 after it hit the low battery warning. It showed four bars for nearly 2 weeks, dropped to three bars and then to two bars within 2 days. It stayed at two bars for a week before dropping to one bar last Monday. I got the low battery warning last Thursday so my charge lasted 3 weeks and 4 days. In that time I averaged less than one hour per day of reading and made roughly 2500 to 3000 page turns. I never shut off the reader, just put it into sleep mode.
In summary:
Four bars: just under 2 weeks
Three bars: 2 days
Two bars: about 1 week
One bar: 4 days
On Thursday I charged it for about 15 minutes so I could continue reading. I am fully charging it right now and can post the results in about a month.
