My phone is always on dark mode whether it is in the morning, afternoon or night. That part of sleeping with the phone on is just me, I will literally be feeling sleepy but still forcing myself to stay online or even watch a movie and at the end of the day I will sleep off with the video still playing and I will just wake up and see that phone battery has gone down bad. I normally update some of my apps sometimes as well but I never switch off my phone unless it goes off by itself lol. Thanks for this amazing tips.
