Help Battery Life Issue

[muraad]

Hello all, this is my first time on this forum. Recently my phone has been acting up. The battery drains extremely fast, it can go from 80% to 75% in 3 minutes. It wasn't like that a couple of days ago so I roamed around the internet trying to look for answers. I thought it might of been an application that I downloaded so I tried Factory Reset twice with no results. I bought two new batteries and yet I still have the same problem. I tried resetting again but nothing happened. When I go in settings > battery > it shows that my Phone (green logo) uses 41% while the rest are at like 21, 10 etc. Is it suppose to be like that? Also that status of my battery says "Discharging", is that normal? I know many people have asked already but please help me. :/
Thank you in advanced.

As you can see the "Phone" is at 40%, how do I reduce it? It seems that that is the main problem.

I forgot to mention my brightness is at its lowest, Wi-Fi, Bluetooth, GPS, etc are turned off most of the time.

Try cleaning your charging port with a clean dry toothbrush then blowing out anything that may still be loose in there.

Thank you but that doesn't seem to be the problem. I think it's because my Calling/Phone (com.android.phone) is being used for more than 40%. I tried force stopping it and everything. I'm not even using it.

You'd be surprised what a dirty port can do. When mine is dirty it turns on driving mode at random.

I tried it and it didn't change anything. It's not my charging port though, it's something in the phone.
