Its not charging while its plugged in why ?..
Hope this helps some.The red X on the battery icon is just telling you that it is not "fast charging", but if you leave the screen off and leave it plugged in to the PC for a few hours, you will see the battery level percentage increase.
That just sounds stupidI had the same problem until I tried one method by accident.
- Connect the tab with the relevant port.
- 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.
- Now you can push in the remaining half of the connector into the slot
Same here, idk why. I am using the charger that came with the Samsung DeviceI have seen red X when connected to PC
The red X only means that you're not consuming battery because the device is taking power from the USB port. As soon as you disconnect the USB cable the red X go away and the battery stars to work.
Some devices (specially tabs) hardly recommend to charge the battery using the charger and NOT the USB connection.
It's an amperage issue. A PC's USB port supplies less than 1 amp, while the wall charger supplies 2.1 amps.
ok people.. the red X does not mean anything other than the power supply detected is not supplying the correct voltage therefore the current usage for charging will be limited to less than 1/2 amps or 500 miliamps. Thats all it means. If the correct voltage is detected then the red X will not appear and the tablet will comsume all current that the supply has to offer up to a maximum limit of 3 amps. If you unplug the tablet from the pc or the charger and the red X was present, the red X will go away because no chargers are being detected.
That being said this part is very important if the red X is driving you nuts.
The red X will only appear if the charging voltage is less than 5.3v.
All computers USB ports are regulated at 5.0V. So you will always get the red X if you plug into a computer.
If you plug into a wall adapter that supplies 5.3v then the red X will go away. BUT remember that the time it takes to charge up will depend upon the amount of current the charger can supply. The Higher the current rating of the charger the faster the tablet will charge.
