I just wish I could find what the problem is.

Li-Ion batteries
do not have a memory. The fuel gauge can need to be calibrated. But, that is really only to ensure the full and empty levels are correct. The only way to calibrate the fuel gauge is to use it. Fully charge it and run it down to empty two or three time.
Your problem does not sound like a calibration problem. It sounds like either a bad battery. Old or failing batteries will behave like this. They appear charge fully, but, as soon as you start using them, they drain a lot quicker.
The other possibility is something draining the battery. A runaway process would do this. The last reports make it sound like the sleep cover is causing the problem. We had a series of reports similar to this a while ago. Turned out the cover in use had something sticking out a bit that touched the screen when it was closed. This prevented the device from going to sleep and made it use lot of power. So, overnight, the battery was drained.
This shouldn't be the case with the Aura H2O2 as it has a capacitive screen. That would require a really badly designed screen that activated the touch. Or you putting it somewhere that did the same or triggered the cover sensor. At one point I kept finding my Glo awake when I didn't expect it. The problem was that I tended to sit it on my iPad, or in my backpack next to the iPad, and its cover triggered the sleep and wake.
The factory reset isn't a bad idea. That resets everything to a know state. Then you can add books and read. For the kepubs, Kobo has plenty of free books. Maybe you can find a few that you like the look of and read them.
