M92 impossible to fully charge
My boox M92 says that the battery is charged at 94% after many hours of charging. Does anybody else have this problem? Can it have a bad influence on the battery?

I once charged mine to 97%, but then I stopped. So I can only confirm that it can be charged to above 94%.

I wondered about this, too. I loaded my device for a long time, but the progress was not as high as I expected.
Moreover the charge amount is not accurate. If you open and close the battery dialog several times, you will see the number alternating. |

Helo, new M92 user here. I am an e-reader newbie so I have a probably very stupid question: when using Onyx Boox readers for the first time is it better to fully charge them (or at least charge them as much as possible, in the case of the M92) or is it better to use them until the battery completely runs out of juice? As far as I know, the second option is the best one with mobile phones but I don't know how things work in the case of e-book readers... Tahnk you!!
I will report whether my device fully charges or not Last edited by Federico F.; 01-11-2012 at 03:23 AM. |

That's a hold over from days gone by. Batteries nowadays are Lithium-Ion (or more rarely Nickel–Metal Hydride) not Nickel-Cadmium which had the memory effect issue. It doesn't matter any more. Charge and use as you see fit.
What is still true is that no matter the tech a battery will lose capacity over time but there's little you can do about it unless you want to put it in a freezer (half charged). Just forget about it and charge when you have the opportunity. |

My device charges up to 100% in a very short time, so hopefully it's not a built-in problem (however just as predicted by Murphy's law my USB cable does not seem to work since my PC does not recognise the device as a removable disk... great!)
EDIT: Now that's weird... the device showed battery charged 100% but now, with the device still plugged in shows battery charge 98%... so I suppose my device too has the same precision/reliability issue Last edited by Federico F.; 01-12-2012 at 03:23 PM. |
