My iconia One 10(B3-A30) takes more than 8 hours to charge.

I bought it 5 days ago, I am using its charger/cable but it's taking a loooooooooong time to reach 100% charge (more than 5 hours!!!!!!

 

Is that normal????

    There are two charging modes and the tablet/charger are supposed to negotiate the best rate when you first connect them. In the lower power mode the charger provides the standard current allowed via the USB standard, which charges very slowly when the tablet is turned on, sometimes only holding it's own and not discharging when you're active. In the high power mode the charger provides something like four times the power for the low mode, and should charge quite quickly when you're not using the tablet and reasonably fast even when you're being active. Sounds like maybe the negotiation isn't happening right and it stays in low power mode? How does the symptom change if you power the tablet completely off then plug in the charger? Try that and give it a couple of hours then report back with how much the charge was increased...

    Had the same problem. Just get a new adapter and cabel or try plugging it into a dedicated wall plug.

    Ok, in order to avoid that power mode I reseted the tablet (factory reset), turned it off and plugged the charger.
    It after more then 10 hours (basically all night long), it reached only 85% of charge....

    I think there's something wrong...

    But where do you get it and what wattage or whatever do you ask for.  I don't know because mine went missing.  I have an Iconia
     B3- A40 and am having difficulty tracking down a replacement.  Didn't think would be this hard!

    The B3-A40 uses a 2A 5V (10W) charger that connects to the microUSB charging port. That's a pretty standard phone charger, so should be easy to find.

    Which model of One 10 do you have? Some versions of Android don't track the battery right and show less than 100% even when the battery is fully charged. You can just ignore it.
