I have only charged it twice and both times its got till about 10% then I have switched it off and charged it for about 4 hours until fully charged.
It then re sets the battery settings like it should and I use it as normal till I switch if off, then when I switch it back on the battery settings re sets to zero This happens for the first 3 or 4 times then it will keep the battery usage like it should until I charge it again.
