I have a Clara HD that seems to be having similar battery problems as some other threads, with the battery dieing while sleeping. One thing in common with this problem is a faulty or 3rd party sleep cover. Except my problem started before and sleep cover was installed.

Currently: Wifi off, Sync off, Autosleep with cover off, Overdrive off, sleep after 15min. Kobo will go from full battery to between 10%, or from 10% to 1%, within 3-4 hours every 2nd day. The battery has never fully died. The clock also seems to change whenever this happens by a random amount of hours.

When the device charges it does take a couple hours (normal I assume?) with no large jumps in battery %. It has been charged to 100% 3 times, and dropped to 1% 3 times. It has not fully died. In use the battery seems perfect. Dropping 1% or so after 2-3 hours reading with a 5% backlight. Which leads me to believe it's a software issue not a hardware issue.

Things I have already tried: Plenty of restarts. A Full reset of the Clara, update to the newest firmware (4.19.14123) with a restart after an hour after the update. Loaded on books (80 or so, using Calibre. All epub, none were converted). Restarted device an hour after the book load.

Next step to try: Unload all books and see if I can download one from the Kobo store to ensure it's not a corrupt book causing the problem.
Any other ideas? Is there a way to log what the device is doing to see if it is constantly waking while sleeping? Just to help narrow down between a software or hardware problem.
If anyone has a fresh copy of what I need to flash on an SD card I'd love try a new SD card with new software incase it's a problem with the OS currently installed. After that it's going be replacing the battery if I can order one.

Last note: This was purchased used about a week ago, so I can't return and likely can't do a warranty replacement. I have no idea what the last owner may have done in terms of loading other software ect, as it was factory reset before I bought (but didn't have the latest firmware)

Help.
