I've had my Acer Iconia One 7 since Christmas.  I've had it plugged in for the last week and the battery is stuck at 1%.  The status bar says it's charging, but never moves from 1%.  I've tried different USB cables, different plugs, and different outlets with the same results.  Any ideas as to what's wrong or what I can do to fix this issue?

    have you tried to charge it when switched off?

    This is normal with some chargers. The charger that came with should have been a 5.35V 2A charger with internal settings that tell the tablet that it's a fast charger. When it's plugged in the tablet goes into fast charge mode and will charge even if you are using it. A standard USB port or USB charger will provide 0.5A and the tablet will only do the slow charge mode. In slow charge mode if you are using the tablet will only hold a charge, not build a charge. If you turn the tablet off it should build a charge even with the slow charger.

    You may check if your are able to use the tablet without the AC adapter pluggedin  eventhough it is stuck at 1%. Some Acer Iconia One 7 have reported this issue. This is not an hardware issue. Acer and Google are working on an update to the operating system to address this problem. This update will automatically be sent to your tablet as soon as it is available. Having the system repaired will not fix this issue. 

     

    For your reference you chekc this weblink  Tablet Charging issue

    You may open thsi weblink and click on "Notify Me " to get an alert from Acer after the update is released for this issue.

    I have the same problem. My tabley is stuck at 2%. I'm trying to reinstall the OS, not wipe data, I wanna delete all the OS. I think is a software issue.

     

    I downloaded the firmware from the acer web page:

     

    http://global-download.acer.com/GDFiles/OS/OS/OS_Acer_Acer.AV0K0.B1-730.RV01RC01.WW.GEN1_A44K_A.zip?acerid=635567119594638672&Step1=TABLET&Step2=ICONIA ONE 7&Step3=B1-730&OS=ALL&LC=es&BC=ACER&SC=EMEA_11

     

    Copied the zip to an SD Card... restart the tablet with the power button and the volume... select "apply update from an sd" but it shows this:

     

    FAILED TO MOUNT /MNT/SDCARD1 (NO SUCH FILE OR DIRECTORY)

    What am I doing wrong?

    The SD card needs to be formatted FAT32 (most are, but some are exFAT or NTFS). Did you extract the file called 'update.zip' from the downloaded zip and place it in the root of the SD card?

    There is not a update.zip file. I downloaded a file called OS_Acer_Acer.AV0K0.B1-730.RV01RC01.WW.GEN1_A44K_A.zip

     

    Inside that zip  are two files:

     

    - B1-730. Install OS from external MircoSD card Standard Operation Procedure..txt

    - SD Acer_AV0K0_B1-730_RV01RC01_WW_GEN1.zip

     

    I renamed the SD Acer_AV0K0_B1-730_RV01RC01_WW_GEN1.zip to UPDATE.zip and copied to the SD root.

    Did the second zip file contain an update.zip, or was it the actual install image inside there?

    Yes I have had exactly the same problem.  Abut a month after buying the tablet it did exactly same thing.  Won't charge past 1%.  But it gets better.  I took it back and they exchanged it for me.  And guess what, it happened again on a brand new tablet.

     

    Both were the Acer Iconia One 7.

     

    Like you I tried different chargers, turning off to charge, turning on to charge.  I stripped it back to factory default.  I loaded battery management software to try to fix it.  Nothing has worked.

     

    Not sure if its coincidence but both times it happened when I left to charge overnight.  Maybe the overcharge control isn't working properly and its screwing the battery.

     

    So I'm going to take back for a refund now.

    Sharanji, that looks a different issue.  Not completely charging seems a better outcome to not being able to get past 1%.

     

    Between my two tablets where it has happened and the original posters tablet, that is 3 tablets failing at exactly 1%.

    I wonder if the issue isn't with the battery/charge but with the software that's deciding the charge level is at 1%. If you turn everything off (full power down via long press of power button) and charge overnight how long the battery would actually last, ignoring the 1% display? If it's several hours then we're likely talking about an issue with the reporting, not with the battery or charger.

    I check that approach and its not that.  As soon as I turned it on the next day it lasted about 5 seconds and powered down again.

    OK, time for warranty repair I'm afraid. Make sure you send both the tablet and charger back. I'm guessing it's going to be a connection problem between the charger socket and the motherboard.

    I am having the same issue with mine not charging and it stays a 1%.  I just got a system update, however I can not install it because my battery will not charge pass 1%.  If this is the update that is suppose to fix the charging issue, please tell me how to bypass the can not install unless your battery is at 40% or charging and battery at 20%?

    Hi All,


    Could I ask for those having issues to share the full model name, such as B1-730HD or A1-830 etc? It will help me review and see if we have an issue being reported frequently to our contact centers and if there is any ongoing research taking place.


    Thanks,
    Cory

    I've initiated discussions internally, I have a few more questions to help us understand.

     

    Does the tablet act like it only has 1% battery? If you unplug it, are you getting minutes of usage before it tries to shutdown?

     

    Are there battery protection measures happening such as a dimming of the display?

     

    Thanks,
    Cory

    My battery meter displays 2% but I can use the tablet for 8 hours without problem. No display dim or any issue.

    To recharge the battery I turn off the tablet and connect it to the AC socket for about 2 or 3 hours or until the power adapter being cold automatically (maybe because the battery reach the 100% load). When I turn on the tablet the battery meter display 2%.
