Hi there. I just recently purchased a battery for my Note 4. Was having issues with the battery that came with the phone so I figured I should buy a spare one. Ad was stating it as a legit product, saying original Samsung blah blah blah. Issue with this is the battery does not charge to 100%, only to 85%. I noticed this in the morning when I woke up ( phone was left on charge over night ). I didn't touch my phone at all in the morning until I got to work. When I looked at my phone, from 85%, it dropped to 73%. I have already contacted the person who I ordered it from, just waiting for a response. Is this normal, I'm I doing something wrong, or is the product defective?? Any advice or help is appreciated. Thank you
