eBooks with errors is the most common reason for problems. My suggestion is to use the calibre editor with the epubcheck plugin to check for errors. If you do find any errors, you will have to fix them. Where is it you get your eBooks from? |

To add to my previous post, I downloaded Kobo Utilities and checked the database which is ok.
I realised that I hadn't done the firmware updates correctly. I did it correctly this time but the issue remains. I didn't load a book through usb this time and opened a book I purchased on the kobo store. Same thing. The cover image and the help pop-up (or whatever is displayed at that time) sort of merge together and it stays like that until I plug it. The device seems to work alright as long as it gets power through USB. Which obviously is not ideal and could indicate an issue with the battery. I just now noticed that when I touch the battery icon it says "99% Full charge in 9.3 hours" which is odd... |

I added to my post before seeing your response. I was running the latest firmware but I have now rolled back to 4.37 which makes no difference. I only have the one book from the Kobo store at the moment. And the time to full charge seems to be going up not down. It now says 9.8 hours. |

I thought the device worked when plugged into power but I was wrong. When I touch the battery icon from within a book the status bar at the top turns black but nothing is displayed, when I then touch the "back to home" button the device reboots, which I think works because it's plugged in. I uplugged it, opened a book, went back and forth between the book and home page and that worked a few times and then it froze again, black background and distorted image of the home page. |

Is there no way to tell definitely if the battery is shot ?
When I picked up the device today the battery was completely drained. I plugged it and after I think less than an hour it said 100% charged. It powered up normally, I unplugged it and keeping my finger on the page turn button I was able to skip through more than a hundred pages before it froze again. I plugged it back in, turned it back on and the battery was at 99%, I unplugged it and I was able to do the same thing again before it froze. Can the battery be bad but still show 100% ? Is there a battery supplier that has been particularly reliable or should I go with one that has good ratings on Aliexpress ? Maybe this is not the right subject for such a question in which case I'm sorry and would post it again in the appropriate thread. |

The battery can have a sudden sag in voltage if it gets taxed or hot, etc., that recovers shortly afterwards. It could well be a weak battery that is on its way out. Another test, if you have the patience and time, is to do the same thing but give it 5-10 seconds between page turns instead of going constantly.

on my KA1:
- e-ink black is now like 50%? after 2021 firmwares - a borrowed Overdrive book after returning no longer has an Overdrive option to Borrow - refresh sucks, even on 1 page mode it takes 3 refreshes to wipe all; devmode toggling of GC16, antialiasing, regal etc all don't help; new settings like throttle etc also |

I was happily reading a book I bought a while ago and removed drm from.
All of a sudden, the kobo complain about drm, that I need to authorize ADE. Anyone had this happening? |

I've seen that a couple times. Generally, restarting the Kobo ereader made it go away.
