Simple Cell Phone Charger Advice

I rarely ask for help, so bear with me while I am vulnerable with you for a moment. I have this issue with my cell phone and I’m wondering if any of our readers can assist me with some advice. 

My phone battery is always dying. 

Look, like everyone, my screen time is usually too high. I’ve got a real habit of keeping all of my apps running (sort of like how I keep ideas ruminating in my head). I often forget to charge my phone at night. Lastly, when my phone gives me warning signs that I need to charge it, I generally push through and see how long I can go before it shuts off. 

What should I do? (And, is this a metaphor for anything?)
