Battery Drains by 30% - 40% After Shutdown and then rebooting it again!

[Yusuf1237]

Since like a week ago my Samsung Galaxy J5 (2016) (which I almost have 1 year) is acting real weird battery wise, I can easily use it throughout the day but at night when I power it off and power it back on the next morning it loses like 30 to 40% battery life for no reasons whatsoever is this a bug or something? or is there something wrong with my battery? Also a heads-up I ordered a new battery for my phone 2 days ago and received it yesterday but the problems seem to have been acting up on the new battery too which is why im posting this, Because I thought maybe my battery was old and about to die so I bought a new one but that one does not seem to help in any way as its having the same problem!

If someone could help me out here!

Welcome.

If the battery discharges with the phone powered off, there may be a serious hardware fault....a short circuit perhaps. Why it only occurs when powered off, I don't know. Try leaving the battery out of the phone overnight, and see whether it still loses charge.

I will try and leave the battery out tonight and see how it will turn out, I also have another question my old battery used to get real hot, to the point that you don't even want to hold the phone anymore now I bought a new battery I don't even have it for 2 days and the same issue is happening with that battery its getting really hot and annoying to hold the phone, also when I received the battery and put it in my phone I didn't even had to charge it up it had the same amount of battery that my old battery had which is kinda weird because I expected the new battery to be completely empty, if anyone has any answers to why this is happening all of a sudden

A hot battery that drains fast is a sign of a short in the phone.

By now i have brought my phone to my local store where i bought it they said they would send it to samsung so they can take a look, hopefully samsung is able to fix it!
