After testing a couple times with a full battery charge, I consistently get 3 days max of Kindle reading. Each sitting is 4 - 5 hours (per day). This is on the font #4 setting. In theory, the smaller the font, the fewer page turns per hour and the least battery drain per day (with wireless off). So those who read using #3 or #2 font may be getting significantly more days between recharges. I'm reading only novels, not newspapers.
Anyone getting longer usage out of a charge? Amazon claims a week! (Perhaps most folks only read 2 hours a day)
Perhaps we can get a log going using the consistent format of:
Novels / Newspaper reading
Hours of usage per day
Days before battery was dead
