Samsung Tablet Battery Icon with a red x Fix 30

Today I would like to look at the issue of a Samsung Tablet Battery Icon with a red X and how to fix it. So if your Samsung tablet is not charging.Plus displays the Red X cross on Battery Icon when plugged in this fix should work for you. Especially if you are using a generic charger or wall brick that you got from somewhere.You know the ones that fit on the end of the USB cable and fits into the wall. It normally works so you simply use it but now you have this issue.

What does the Battery Icon with Red X mean?

The battery icon with red x indicates that the device is not charging or is a not charging icon.

Why am I seeing the Battery icon with Red X ?

This icon only appears on Samsung Tablets or other devices when the wrong charger is connected. Samsung based tablets detect if the charger is a original Charger and if not limits the chargers power and displays the not charging icon or the battery icon with the Red X. The device then does not charge because of the low power or amperage of the charger.

Samsung Tablet Battery Icon with a red x

Whats Happening Exactly?

When Samsung detects and limits a non original charger the charger only is allowed to deliver about 0.4 or 0.5 Amps of power. The normal charger supplies about 1.35 Amps of power and will charge the tablet fine. For comparison your computer regular USB 2.0 ports supplies about 0.5 Amps of power.

How to fix Samsung tablet not charging?

To fix Samsung tablet not charging Issue with Red X you simply need to in most cases is to get a Original OEM Samsung tablet charger  that works with your model tablet. If you were using a generic charger brick that’s not from Samsung as was mentioned above Samsung tends to limit the power most likely for your own safety.

Other things you can try:

You may also try any of the following in an attempt to fix your problem although getting a new charger tends to fix this issues:

1. Reboot the tablet, do this by long pressing the power button and power off and then on again.

2. If you are using the original charger make sure its functioning correctly and the USB cable has no shorts or breaks in the wires in the cable that may affect charging.

3. If you have a friend with a similar device you can confirm its the charger or cable by simply borrowing their charger.

4. If you have a battery bank you can use the USB end and try charging from that and see if that also works as a workaround.

    My tablet started to showing the X. When I moved the cable around, in the charging port, trying to place it well, it would go away. But I ended up damaging the charging port. So I replaced it. Now I still have the same problem. This is so annoying. I will buy a new charger. Hopefully it will work. Thanks for the article.

        I was using a generic charger for my Samsung tab a6. I would get the red x when I plugged in my device and it wouldn’t charge unless I powered it down, so essentially rendering me communicationless for a few hours a day. Even when I charged it overnight, it would take a lot longer than usual to get it to full charge. I bought a samsung charger from a friend and it has been back to nominal efficiency, thank you for this post. it helped a lot.

  • Gerald

    It was not very helpful!
    It is obvious that the original will work.
    Would be much more helpful to get information what Samsung is doing to prevent using gerneric chargers…..

  • Sabrina

    Mine has the red x, when I go to reboot, it goes into download mode and wont leave that till the charge runs out. No rdboot will work at all! I have tried everything I can find and nothing works. Did a total wipe did not work. Virus and malware check, did not work. Ugg what can it be?

    • Anonymous Indonesia

      My speculation you have a problem with hardware and the problem is on your volume up button. So when you booting the phone, it will going to download mode by it self.

  • Vic

    I have a Tab2 and I have this red cross problem for more then two years now. I have always been using OEM products to charge. Now my Tab4 has the same problem! I think it is the OS causing this problem. I never found an official Samsung answer/solution on this problem online.

        Hi Ricardo, ive had my Samsung Galaxy Tab A for less than 7 days, i got it brand new direct from the virgin warehouse so not a refurbished or second hand tablet.
        The tablet also came with all the correct and approved Samsung charging equipment yet from my first attempt trying to charge it ive had problems.
        If i put the device on charge using just the wire attaching the USB end directly into my computer or by using the wire and wall plug the only way i can successfully charge my tablet it is to completely switch it off and keep it switched off until its fully charged again.
        If i try to charge it whilst keeping the power on and/or whilst its still in use, it does not matter which method i try to use ( charging using the wire only or the wire and wall plug ) i cannot get it to charge all i get is a red X over the battery icon.
        Even though i know its the correct wire and everything else i have tried all of your suggestions without any success, do you have any other ideas about how i could try to fix this issue, all and any suggestions ( sensible only ) will be gratefully received.
        many thanks,

          Emma PiXi – I have the same issue here with my daughters Tab 10.1

          Exactly the same issue. It only started to happen when we had periods where she let the battery drain down below 5% or so and then we had to go through various tips to get it charging again. After that occurred several times I installed a battery low alarm so she would know when it was too low and quickly put it on charge.

          However since we got the charging to work again we now have the issue you’re describing, whereby the low power trickle charge from a USB port on a PC/laptop will charge the tab but charging it from a wall socket won’t work. Also experience the same issue whereby it won’t charge while switched on.

          Very frustrating

    Hello my samsung galaxy tablet a6 not charged when table is turn on…and when tablet is turn off battery charge starting…why can u help me mr?:)

  • Teri

    I don’t understand why other universal chargers don’t work with my Tablet. I left my charger on a small hotel and when I called them they said they didn’t find it. So then do I have to buy a new charger?

  • Mary Gilbaugh

    Thank you. I understand the problem better. I am using the cord and charger that came with my tablet. The red X remains. I can get the battery to charge when connected by USB 2.0 port on my laptop. It will not charge when plugged it an outlet with all original equipment. Now what? Am I to understand it is not the battery?

  • Mary

    Thank you so much for explaining to me that this problem has to do with the cord and charger. I got a Samsung OEM charger and new cord on Amazon for $10, plugged it into the tablet and a wall outlet and it charges perfectly!! You were very helpful.

  • carlos

    Sorry, but absolute rubbish mine shows red x on one insertion black on the next at random………and no help….just a sales ad for samung chargers……
    What about an app or something to disable this ridiculous charger check…….

    • Ricardo Gardener Post author

      Hey Carlos glad to see you are so spirited you will need that in order to actually fix this issue. First the suggestion with the charger is actually a legit one as I have seen it fix such issues. You can easily borrow a original charger and test your device the link to the charger is merely a convenient link in case you wanted to buy one and nothing else as you are not forced to use it. Also as per your suggestion regarding a charge check app to disable the check I suggest you take up your plight with Samsung I am sure they will take kindly to your warming and polite comments.

      Hey there! I have noticed it has nothing to do with bad battery or cable or charger(in most cases). I’m owning 3 Samsung tabs and red cross over battery started to show up after official software update. When I updated my first tablet resulted in red cross over battery – I first thought my battery dead or cable or …. but after I update second tablet – now on my second tablet is a red cross. Third tabled updated and same thing happened. I believe the new update has something to do how tablet monitors charging and there is some software Bug (incompatibility with some tabs). That explains way the new tablet owners has the same issue here.

    • James

      I will add one more ‘trick’. Make sure the cable is fully plugged into charger and connecting to tablet last. My tablet a6 will show the red x if the cable is even a tiny bit not fully pushed in.

      I also feel that just buy another charger to go along the box full of working charger I have is not exactly a fantastic answer. Having a solution that will work with any charger would be much more helpful.

    OH MY GOD!!!
    Now I own a Tab3 and Tab10.1 since a couple of years. and I lived with these red crosses on both since almost after a couple of months of purchase (second hand). I was about to give them away for a few bucks because it’s annoying to charge them overnight to use em for a couple of hours. Now saw this post: it’s the first time that someone supposes the use of a POWER BANK !!!, I connected the TAB3 and voila: no red cross and charging. Incredibly unbelievable that all my chargers at home are overrated….
    Thank you so much …

  • Sonny

    I have a Tab 8.4 pro T320 and it is giving me this red cross on the battery, I’ve been using it with an USB cable on my computer for many years but now it comes up. Other ports on the computer gives same result even a USB3 port. So there must be more happening than just not enough power coming out of the port.? On a powerbank with 2A output it is gone. Still I feel it’s weird it’s popping up now after many years in use on the computer.

  • D. Roberts

    Your solution didn’t work, even though I used the charge cord that came with the tablet and that charge cord works fine with my phone.

  • ullisse

    My solution wok
    1.Connect the tab with the relevant port.
    2.Now slowly connect the USB side of the connector to the USB port in your computer (remember to be slow enough till 50 percent of the connector is pushed in).
    Your tablet will now start charging normally using the PC.
    3.Now you can push in the remaining half of the connector into the slot
