Samsung j7 2016 battery issue

[fakeprince]

well guys as the title says i am having battery drain issue with my j7 2016 who's 1 yr local warranty just ended last month.the battery will drop very fast from 30% to 0 %.
so i want to buy a new but "ORIGINAL" battery ,the market z full of copy ones.
I checked saddar rwp singapore plaza connect mobile were offering orignal one for 850rs and as per their statement the same one that comes in the box for last 1200 rs.
but they were silverish grey rather than the bit dark grey one that came with the phone.
i checked samsung store locator and they were also selling original one but for 1800rs .This is the one that came with the phone (EB-BJ710CBE)

Either get a guarantee from the Samsung store in writing that the battery is legit or go to the M&P service center with your phone and warranty card and buy an original battery from them.

so i bought a new battery from official samsung store . but the issue still remains the same it seems some kind of software thingy that i charge my phone 100% of which first 88% it charges like the normal j7 2016 speed but last 12 % it takes just 5 odd min the same thing happens with other battery too both orignal j7 2016 oem batteries.so as a result it does give a great screen on time around 6 hrs up till 18% then the remaining 18% drops like in 5 min to max 7 odd min.

Open the dialer app, dial *#9900#, scroll to the bottom, click BATTERYSTATS reset and then do a full factory reset on your phone. Do this while the battery is low, around 5 or 10%.

After that when it boots up, before going through the setup wizard, power off the phone.

Connect the charger while the phone is powered off and let it charge to 100% fully. Then boot up and set up the phone as you normally would.
