Device updated to ver 184.108.40.206. Every since update battery just drains for no reason. Last night fully charged 100%, no reading or use this morning checked battery 40%, no reading no use now battery at 18%. Can't figure out why. Can't find any help on new improvements swippble home and personalized reading.
the promised battery life on an Oasis = "A single charge lasts up to six weeks, based on a half hour of reading per day with wireless and Bluetooth off and the light setting at 10. Battery life will vary based on light settings, wireless usage. Audible audiobook streaming over Bluetooth will reduce battery life."
this = (6 weeks X 7 days) X .5 hours = 21 hours which is, if I remember correctly, what the Voyage promised.
did you reboot the device (hold power on for a full 30 seconds)?
make sure it wasn't too full?
make sure you don't have a book or books stuck indexing? This is the most common reason for rapid battery depletion on Kindles.
as far as the Voyage goes, mine is eating up the battery a bit faster than it used to. It has the same OS build as the Oasis. However, I tend to have to charge it every few days anyway as I don't let it get below 40% and I read fast (more page turns than most people), keep the illumination around 20 and read 4-5 hours a day.
also, I'm wondering if the time might have been calculated using button page turns or touchscreen pages turns and if there's a difference in battery usage between the two methods.
