Default [Q] GT 3110 (Tab 2 7 inch) charging issue

Hi all, new member here so thanks to all for one of the best and most useful android forum out there!

I'm having minor problems with charging my tab 2. At best it is incredibly slow - 9 hours in flight mode last night! At worst it will actually discharge whilst plugged in and in use. I'm using slim ROM 4.4.2 weekly. I'm not sure what other information may be required to shed light or hopefully solve this but I am happy to provide any data. I've included last nights charge info for starters. So far I've not discovered any other such faults posted anywhere and I've ruled out power lead\cable and charge point as an issue through basic diagnosis.

Look forward to hearing from someone who may be able to help!
