Hi bought this samsung note 8 when it came first in the market, my note 8 still intact with original transparent cover front and back and hardly used. All a sudden it stopped working as battery was dying due the old ageing. i removed the battery and trying to connect directly to power but it doesnt turn on. does it need battery to turn on? i noticed some devices can be used if you connect them directly to power source. Why is it not getting on? never drop, never spill water, always packed in box.
