samsung galaxy tab 3 8 inch not charging

[sweetsos209]

Something is wrong with My samsung galaxy tab 3. If i use it while its charging the power goes down. If i let it charge by itself it goes for 15% in 3 hours. For example my battery was on on 7% at 6:00 pm. I wake up at 2:00 a. m and its only on 27%. Samething happened yesterday but it went from 7% to 9% in the same exact same Time frame. One time my battery was at 30% and in less than a min. Went to 1%. I don't know what to do, i cant take the battery out because i dont wanna break the cord. Turning it
off and on wont work.

Assuming the battery is working properly, what you could check is the power cord and the port where you plug in the charger to the tab. If there is any dirt or dust, you could try blowing it out both from the port on tablet and the cable. If this doesn't help and you have at home another android usb cable, try charging with that one.

Are you using the original Samsung charger and cable?
The tablet requires 2.1 amps to charge, if you use another charger it may not put out enough amperage.
Many phone chargers and PC's only put out .5 amps.
