Samsung Tab3 311 Charging problem 30

Last month I bought the Samsung’s latest launch Galaxy Tab3 311. It has an 8 inch screen with 1.5 GHz dual core processor. (More details here). However, within a fortnight of purchasing the device, it began showing charging problem. On primary investigation I found the problem was with the USB charging adapter which came with it (The device would charge from other Samsung mobile chargers while the adapter won’t charge any other mobile/ device.)

For a remedy came the idea of charging it via my laptop and so with much pleasure I connected it with the laptop and alas… it won’t charge and instead showed a red colored cross mark over the battery level symbol. On this I Googled to check if anyone else had the same issue? Some had, but they all were related to Tab 2. But on reading the problem description and proposed solutions I knew this might as well be the case with me.

Problem Reason:
Now let’s come to the actual problem. If you happen to read the adapter input output reading for the Galaxy Tab3 311, It says Input voltage range of 150-300V while the output voltage is 5V. However the interesting part is the output current parameter where it says to be of 2A (Ampere). And this is the problematic part. On searching in the market for alternate adapter I could not find any which would have these output parameters, specifically the current value. And also the usual laptop USB 2.0 port provides a current of approximately 500mA range. This is rather low to start charging a tablet.

If you really wish to charge your Tab from your laptop, simply switch it off and now connect it to the laptop. It should begin charging the battery (However at a very slow rate, I had to wait for about 6Hrs for only 75% charging, but then it’s better than nothing.)

Hope it helps. 🙂

      Hello Surya,
      As per your description it does seem that your charger is working fine while your device isn’t.
      You should get it checked at the service center if the problem persists (Since we can’t think of any other possible troubleshooting combination as of now).
      If you could find time to post here how you resolved the problem then it would be a great help to all 🙂 .

    I had this problem a lot, the rememdy I found was to press and hold the volume up and power buttons until the Tab turned itself off and the flash screen (Samsung Tab 3 screen) appeared.

    After awhile a text based screen will appear with a menu, choose reboot (volume buttons move the cursor up and down, and power button selects).

    The Tab should now reboot and then let you charge from the charger.

    I have the same Tab3-311 8 incher. My tab also developed the same problem and I gave it to the service centre but they could not solve it properly. I came across reading some online help that suggests to long press the power button while connected to the wall socket. It refreshes the battery properties and then another press of the power button would restart the device and help the battery start recharging. Actually the service centre guys might have just restarted the device while it was connected to the wall socket and it started to charge, and told me that it required just cleaning the USB port. But immediately the problem sprang up and since then have been refreshing the battery properties as often as the charging problem recurs. I am thinking it is a software problem. But I find the problem is getting worse day by day, having to restart the device several times during the day.
    Charging through laptop is a painstaking exercise!
    If you come across a good solution, please post.

    Seems like both Dharmendar and Dwayne are telling about similar solutions.
    Thanks for sharing your experiences here 🙂
    Actually the problem in our case was that the charging adapter wasn’t working even with any other devices. It had to be replaced ultimately.
    Have any of you tried the charger with any other device? Or tried charging your device with other well functioning charger?

      Hello Kulbir,
      “Some time” refers that this is not a regular problem and is occurring on a random basis.
      Could you identify some other scenarios for the problem and also check your system memory whether it is getting full?

    The issue is that T311 tabs battery is too big to charge when connected to computer USB. It will charge very slowly though Battery status in Settings would say that it is not charging.

    Even I have to restart the tab and then connect to the mains for proper charging

    I ma facing the same problem as that of Surya’s, i have to restart my Tab and then only it charges every time. What could be the reason?

  10. Reply Mehdi Jul 26,2014 6:12 pm

    The same problem. Sometimes I leave my tab for charging and when I come back I see it was not charged, even It lost the energy, let’s say, before it was 45% but now it is 10%.
    I also think that, it is software problem. I am confused what can we do. Actually I am electronic engineer. I will take readings, voltage an current during charging. I’ll inform you if any news.

    yea guys i hv got the same issue here…. charging taking too much time with the charger… service center guy told that there may be issue with the wire of the charger !!

    Hi mates,
    I have the same charging issue and one more. The tablet is being stacked (black screen, nothing happened with buttons) because of my smart cover (with the magnet, smart on/off). I have to restart the tablet by pressing power button about 10 secs. Then the tablet seems to work fine.
    I don’t know what to do and I haven’ tried to flash any custom rom.
    Any ideas?

      Hmm.. have you recently updated the device for the latest Android Kitkat update? If it is so then it seems you too are caught in the update problem. We’ve recently faced the same and are about to make a post about this.
      If this is not the case then other issues may involve lack of memory due to some process taking too much of RAM or heating of the device because of some process taking too much of CPU.

    I’ve been having similar problems for about 6 months–my Tab3 is not quite a year old.

    It seems almost random–sometimes it charges totally as expected. At other times it can be plugged into the charger for near 24 hours, and only charge to 40% or so. I’ve tried powering it down and restarting, clearing cache, changing chargers, changing cords–nothing consistently helps.

    It seems to charge best when it’s in use and plugged into the charger. There were some postings on another site about a year ago about opening the unit and disconnecting, then re-connecting a wire on the battery. I really don’t want to do this, since it voids the warranty.

    I can’t find anything that specifically brings on the problem, nor that changes when it charges correctly (which is rare). I’ll be watching to see if anyone has a suggestion.

      Thanks Dennis for sharing your experience. Yeah it does behave strangely sometimes and we too have been unable to find any sane explanation or possible solution for the same so far.

    I have been through many forums, conclusions, solutions and service center calls, replacing the USB port, restoring to factory default, but nothing came up with the exact solution.

    I have been going through a random check by myself, and i noticed one strange thing which is not allowing to charge the TAB, which was Manual Brightness mode, if i keep Auto Brightness mode connected to wall Charger which was supplied with the box (2 AMP 5V charger) it starts charging normally.

    i tried to check it randomly, if i keep Manual Brightness mode and charge the TAB at 44%, checking after an hour, it remains at 44% only, but if i change the Brightness mode to Auto mode, within 10mins, it shows 48% from 44%, thats really strange, but fortunately it worked for me.

    if anyone come across to this type of solution, then let me know.

    facing the same problems charging is very bad take tow days to charge my tablet311. would any one tell me whats wrong with it

    my regards to u

      Whoa.. Two days a lot of time. Is it using the charger provided?
      Have you checked the battery consumption details? I mean which apps are consuming most of the battery? You can check this in the settings menu.

    I have a Tab 3 7″ and it can go down with charge. The battery full charge
    is 4.2 volts. I charged a battery to 100% 4.2 volts FROM A EXTERNAL 4.2 VOLT CHARGER CONNECTED RIGHT TO THE BATTERY and the tab showed 100% charge. Using the USB charger that is 2 amps just makes the charge less
    in other words drains the battery. When on charge my meter shows no more
    than 3.8 volts and never more than that. This is something Samsung needs to fix because so many people have the same problem. I am thinking of bringing out 2 wires from the battery and using a charger from Ebay that is made for 18650 Li-ion battery they are less than $5.
    Anybody know of a class action lawsuit about this it sure looks like enough people have this problem.
