why is my phone battery draining so fast?

lately, it feels like my phone battery barely lasts half a day. i used to get through the entire day without a problem, but now i'm constantly hunting for a charger. anyone else experienced this? maybe it's all the apps running in the background or maybe i need to tweak some settings. i've heard things like adjusting screen brightness or turning off location services might help. has anyone tried these or have other tips? would love to hear what worked for you. btw, if it matters, i'm using a samsung galaxy and it's just over a year old. here's a pic of my battery usage from today: [insert link to image] 🤔🔋
