So a couple days ago my daughters Samsung tab tablet has had problems with the battery %. If I charge it to 100% it drops to 90 then 70 and so on to 1% then holds there in a matter of about 5 min. After that it maintains the 1% for 5 to 7 hours. I have searched alot on this, done bump charge, factory reset and recalibrate the battery. Normaly it wouldent be a issue sense it's full life is there but it going below 5% causes the tablet to go into a battery saver mode and cuts cpu usage and screen brightness and no way to adjust it back when it drops that low any help would be appreciated!
