What version of android does your cell phone have? 
I have carried out different tests to find the problem, when I went to sleep the phone had 91% battery, I left it in airplane mode and after 6 hours without using it I had 70%, check the history of use of the battery but it does not record any application. I use Greenify app to keep apps sleeping. Also disable all smart assistant functions. I have always used only the original charger.

How long does it take for your phones to charge from 20% to 100%?

I tried greenify, amplify and other deepsleep apps. Now use none of them. I found on stock rom some great things to control battery life. Go to settings, smart assistant, app blocker. Enable it, take the adjustmemts to all apps as You want to. Check battery optimising in settings and make adjustments. Enable DuraSpeed. I am ok with my battery life now, I get 36h easily, while I use smartphone a lot. If in standby with battery fully charged I suppose I get about 1 week battery time... I will try out this night with battery widget reborn app.
