This morning, when I woke up my phone was out of battery power. So when I checked the battery usage I see the message
Display had been used 90%.
This kind of situation had never happened to me before. I was surprised as I always turn off my mobile screen by clicking the power button.
Why has this happened even though I turn off my screen?
How can I avoid that kind of situation from happening?
