Before you spend money on a new charger or even a new battery & well before you consider taking your tablet apart to touch or solder anything try this that I read on a different post on this site. First disconnect your tablet from the power cord. Then hold down the on/off button for 30 seconds & while STILL HOLDING DOWN the POWER BUTTON, SLOWLY insert the power cable. Continue to hold down the power button for up to 30 seconds, AND VOILA, PRESTO, it was fixed WITHOUT taking the Tablet apart, WITHOUT spending a dime or even a penny!!!
Its probably because you are using it whilst it is charging, let it charge when your not using it,or just let it charge for some time. If it still doesnt work,go to the shops and get your ipad/tablet thing checked. And make sure to take the charger with you, because it could be a problem with the charger
I have a Samsung note pro 12 inch only 4 months old and suddenly the battery wouldn't charge when I was on it or even on standby. It was also very slow when the tablet was off overnight. I'm in France and using a proper Samsung charger. I have just discovered that if I turn the charger the "wrong" way up it is charging like it used to do. I used to have it going via an extension cable and I think it was just fluke that I had it plugged in the right way round as the extension socket was on the floor, not vertical as when a wall socket. Hope this helps someone - only really relevant if you are using a 2 pin plug...
