Why is my battery running out in two days?

[AC Question]

Hi. My android smartphone is running out of battery in two days from a full charge. I have no battery wasting apps and games, and only the apps that were installed by the factory (and a few other apps that don't make it run out). I have tried everything, and now, I have to charge it every two days, as I don't know what is happening. It used to run out in a week!

What do your battery usage stats indicate after such discharge?

Two days? Shut up. If I got more than 7 hours I would be happy.
