Battery: Red "X" and Lightening Bolt

**Pia Macchiato** · 02-26-2013, 09:25 PM

Why is there a red "x" and lightening bolt on the battery icon of my Galaxy Tab 7.0 Plus tablet? How do I fix this? Thanks. It also says that it is charging even when not plugged into adapter. When I am about to shut down the tablet it shows big battery charging from 100% to 80% with out being plugged in. Help!

Are you using an OEM Samsung charger that is plugged into a wall outlet, or a third-party charger/USB charging connection? The red 'x' charging indicator can be caused by not using an official charger. As for thinking it's charging when not plugged in and strange battery behavior, that may indicate a problem with the charging port, power circuits, or the battery itself.

Usually, if the red "X" appears on the battery icon the tab is charged at a lower Amp. An example is when you attach it to the USB port of your computer. The lightning bolt appears when the charge Amp rating is correct, this is the case when plugging/using the wall charger to charge your tab. Both methods can charge your battery but the "red X" charging takes a lot longer. If you see both at the same time, maybe its time to head down to your Samsung repair shop.

Anim@l may be right. It's possible that the tablet think's it's charging at a slower rate or with an improper charger because of damage to the charging cable or to the charging port. First, I would try charging with a completely different official Samsung charger. If that works, you know that the charger was the problem. If it still doesn't work, it may be a problem with the tablet's charging port, and you may have to have it fixed.

Make sure there isn't any debris in the charging port on the tablet. If you can get your hands on one of those compressed air dusters, they work wonders for clearing out ports.

Update:
I bought a PowerBank a couple of weeks ago for my to power up my devices. It comes with the cable and adapters so it fits my Note 2 and Tab plus.
I used the same cable to charge my devices in the office using my laptop.
The red "X" does not appear anymore not like when I used to use the cable from the OEM charger.
But the drawback is the cable is not for data because I could not access my device when it connected to the laptop.
With this in mind, I used the 3rd party cable for charging and the OEM cable for data access.

Yea, ive been having this problem as well. I dont think this is a false cord because it came with the device. I have a samsung galaxy tab 2 and I am verry frusterated because irs not charging. I would like someone to help me aswell if you can. My email is

It might be because it has a burnt cable so you smell your usb cable

I just bought a samsung galaxy tab 2 7.0 today and at first it was taking a perfect charge and then my wife plugged the cord into a usb splitter hooked into the oem outlet charger, in hopes to charge both my new galaxy tab and her ipad at the same time...

didn't sound like too bad of an idea at first, but as I'm sure you can guess, it was. Now there's a red X over the battery when charging, and it says that the device is not charging, but it is, just veeeeery slowly...

I'm hoping dearly that it's just the cable that got "burnt", but I'm expecting the worst. Can anybody please fill me in on any more information as to my problem, and more importantly, the solution? Thanks guys. Be nice, I'm a noob

Try charging your tab2 with its OEM charger.
If the red "X" still appears, without disconnecting it from the OEM charger, restart your tab2 and hopefully the red "X" will disappear.

Thanks for the suggestion. I actually was able to resolve this problem myself thankfully!

Well, I had thought that I had been using an OEM tab 2 charger, but after I checked into it a little bit, I figured out they what I had received when buying the tab (second hand) was in fact the OEM wall plug for a Samsung galaxy s3 smartphone. Turns out they are amped totally different. I went to the local att store and looked at the voltage/watts/amps of all the usb wall chargers until I found one with the exact same specs, and bought it, roughly $30. I didn't have the highest of hopes but I took it home and plugged it in, to my amazement, no more red X while charging! Hooray! Talk about major relief... Hope my post can help someone else, this seems to be a pretty popular problem.

Glad to hear you got it solved.
Anyways, it would have been a very low charger mA you have there.
Sometimes, I charge my P6200 using my powerbank port with 500mA and the red "X" will not appear.
Charging is slow though but at least I wont run out of juice while I dont have a wall outlet to plug into.
