Battery automatically draining overnight

[anoymous_user]

Hi guys I'm using samsung galaxy j5. I'm facing a huge problem of battery drainage in my phone. Very last night I saw my phone charging 50 % and next morning it was showing charging only 20 % even I didn't used it. Can anyone tell me how can I solve this problem?

Please replace your battery

I've just changed my battery last month but still problem is coming

Please make sure are you using Samsung approved battery?
Or replace the battery properly you have used.

It's the original battery and I have bought it from samsung service centre

So please check the battery and replace the battery. I think you haven't set the battery properly. Or contact with your nearest Service Centre as soon as possible.
