I bought a Samsung Galaxy S5 and opened the box, read the manual and everything, then i turned it on. I used it until the battery had 15% then i turned it off and then i started charging it (used the wall charge attachment). When i checked back after 30 minutes the screen showed 12%. I came back another 30 minutes then it was on 9%!
Why is it losing battery rather than charging up?
Do i have to drain it fully to 0% before i charge it?
(i bought it from Kogan btw)
