Battery drain without use

Hello there, my problem is that when I leave my phone charged and with a percentage of battery, when I go to sleep and wake up the next day, it has 12% less battery. Which I do not see very eloquent to say. Since first my phone is new and I have almost a month with it. Here I will attach the screenshots of the battery usage as it is declining.

Here you can see that I didn't use anything and still the battery was constantly dropping. It should be noted that in the settings I have the background app refresh disable. Even this happens to me with the airplane mode activated. If anyone can help me thank you.
