This battery is clearly not an original Samsung battery! While looks just merely the cuff with the printing feels kinda stuck on what should have given me food for thought! The original Samsung battery lasts (with normal use) about 30 hours, This Fake you can almost see how empty it! After 5 hours (without significant use!) Already only 50% charge !!! Even though the battery is already fully charged and 5x Also every time (almost) been fully discharged! With this battery and the Samsung Galaxy Note is never comes on the day (certainly not a working day)! So steer clear of this fake!
