I just can't understand how things that were introduced in much earlier Android versions and are working properly on thousands of various device cannot work on this one.
I fully charged it yesterday and then put in standby. With the wifi on, true.
Today it's depleted.
My phone, my tablet, how can they cope with this situation and don't deplete and this reader that has nothing pretty much to do while in standby can't ?!
