Ah. I keep my KFv1 at 1.6% when the lights are on and 0.8% when in the dark. I get about 12 hours of reading time. It uses little to no battery in sleep mode. I charged my Kindle Fire Friday night. Left for North Carolina the next day. I decided at the last minute not to take it with me due to not having a good case. So we got back late last night and it was at 98% I love my little tablet!
