Kindle Paperwhite charging problem

Tune Tune · 11-22-2012, 12:11 PM

My Kindle Paperwhite turned green light after about 4 hour charging but when I disconnected it from the usb cable, on it screen there was a little bit blank space in the battery icon. I mean that despite the Kindle was fully charged (the led light turned green), after it was disconnected from the electric source, the battery icon still not covered all by white color, there was a little black space in this icon as it was only charged to ~95-98%. It appeared from the first time when I charged this Kindle.

Everybody, did you experience this problem?

I've had that happen after updating my Kindle Keyboard to the latest firmware. A reboot solved the problem.

It takes several charge cycles to correctly calibrate the battery meter. Don't worry about it.

Until now, my Kindle Paperwhite has charged 3 times but this problem still appears

exactly how many charge-times does it need to calibrate its battery meter?

P/s: Does your Kindle Paperwhite show notification on its screen when it was fully charged? Mine does not. Despite it was charged more than 4 hours and the led light already turned from orange to green color, it still showed a lightning icon inside the battery icon. This lightning icon still existed despite I had tried to charge the Kindle Paperwhite 5-6 hours.

After that, I disconnected the Kindle Paperwhite out of electric source then I re-connected it to electric source via its USB cable to charge again immediately. Guess what happened? The led light turned on with orange color, and after it was re-charged about ~ 30 seconds, the led light turned green color.

I don't know what happened with my paperwhite. Please give me some advices.

Form my experience with Kindle Fire, battery indicator turns green somewhere around 92-95%, it doesn't wait until is fully charged. If you leave it on charger for about half an hour or even whole hour, it will be fully charged. Haven't noticed this behavior on PW, but generaly, if your battery life is good, forget about that.

What you describe is normal and to be expected. All it means is that the battery is start draining the moment you unplug the USB charger.

This does not indicate in any way that the battery life is poor. Mine behaves like yours too but mine lasted 49.5 hours continuous reading with LED off and 13.5 hours with LED at level 24 (full blast). If you compare that to official Amazon account, it is actually last far longer than expected.

Let at least one cycle discharge down to the screen where a large battery icon is shown plus icons for a wire and a lightning bolt for the power.

Then charge overnight. That will train the battery meter to conform to an actual cycle.

Sorry, I don't really get your idea. Do you mean that I should use my kindle paperwhite until the battery is totally drained out (0% battery left) then charge it overnight (about 8 hours) for training the battery meter?

That's certainly the fastest way to get an accurate battery meter reading, yes.

Yes, when totally empty, that screen will appear. It will also allow your battery to last much longer in the future since the chemicals within the battery get fully mixed that way.

I saw that mentioned on Amazon by a producer of solar charged storage lithium batteries when folks were complaining the batteries did not last as long as the stated parameters.

I've had this problem with both my Paperwhite and Kindle Keyboard. Restarts and resets did not fix the problem for me.

Have you tried a Factory Reset?

lizard king · 10-21-2013, 12:43 PM

about 3-4 times

HarryT · 10-21-2013, 12:49 PM

How do you know that it's not fully charged? Are you getting a battery life that's significantly less than Amazon state? You really can't go by the battery meter - it only gives the roughest of indications.
