iPhone 5 jumping from 1440 mAh (0% wear level) to 300 mAh (79% wear level) in just one night

This morning I woke up and went to school and when I got out, I saw the battery around 30% (in a normal day I would come home and have my phone at 80%), and I haven't used my phone like just 2 times, cheking the clock. I have this battery from 29 december and I downloaded a battery wear level app and till now I had it around 3%, and all of a sudden I had it around 79% in just ONE night. Can you please help me? Thanks 🙂

iPhone 5, iOS 10.3.3, Battery

Have you noticed a significant decrease in battery life? Keep in mind that after iOS 9, battery wear level apps are pretty much useless, as Apple disabled the majority of the features that make them work (How many cycles they've been through, temperatures, etc.)
