Clara HD battery unreliable when below 30%
I've been having repeated issues where if my Clara HD shows a battery at 30% or below, I can more or less guarantee it will be dead by morning. 30% is apparently the new 5% for my Clara.
I've done everything I can to try to eliminate ambient drain. I turn off WiFi unless I'm syncing something. I keep the screen at no brighter than 5%. I have a sleep cover, but I turned the sleep cover functionality off because I suspected maybe it was inadvertently waking it up somehow. So now sleeping is completely manual, and I hit the power button every time before I close the lid, and confirm that the backlight turns off.
No luck. I don't understand what could be causing it. And surely if the battery reading were inaccurate, the battery would have recalibrated itself by now, because it has done this for my last five charges (that is to say, I found my Kobo completely drained before recharging it, so that should have been five full cycles).
It's driving me nuts, because on weeknights I generally don't check my Kobo until I'm settling down in the evening for bed, at which point I find it's dead, and I can't use it until the following day because I have to wait for it to charge.
What else can I do?
