Should I be worried?

I just purchased a Clara HD for my son. My first impression is that it is a nice compact device.

I set it up, it updated the firmware to the most recent (4.33.19611) and sideloaded some content. No patching or other modification. It seemed fine. Battery was at 50%. I gave it to my son.

A couple of days later he gives it back and says the power button isn't working. Some of the screen looks a little weird and the power button doesn't do anything. I plug it in, and it starts to work. Battery is at 50%. As soon as I unplug it, a similar problem occurs. I do a factory reset from the UI (Settings-Device details), and still have similar problems: as soon as I unplug it, there are problems.

I charge to 100%, and it seems fine now.

So was it just that it needed to be charged? It needed to go through battery calibration?

I'm a little worried because I never got a low battery warning, and if it is a hardware problem, I would like to return it to Walmart instead of dealing with Kobo and warranty replacement.

What do you think?
Thanks.

How did the screen look?

I’d be worried though that’s certainly not normal behavior. Exchange if you can.

Some parts of the screen looked inverted. Notan entire section, just every couple of lines, and some pixels within a line.

It seemed strange to me that it happened as soon as I unplugged it and then tapped on something, and when I did a full charge the problem went away.

I stand by what I said. Something is funky with that Clara. It might be working now but it could be a lurking issue. Maybe wait a few days I don’t know your return/exchange window.

Not helping here - but I think I would exchange it too.

Do you know what the battery capacity was before you started to use it? Just interested to know if there was a large change in that short time frame to get to 50%.

It was at 50% out of the box.

An update, in case anyone else has similar problems.

I decided not to exchange it. I charged it to 100% after the initial problem, and it seems fine now. I've since charged it a couple times, and all seems well.

I probably should have exchanged it to be on the safe side. Thank you all for the help.
