phone battery draining too fast, any tips?

So I've got this phone that's only about a year old, but the battery seems to be draining way faster than it used to. I remember the days when a full charge would easily last me through the whole day, but now I'm barely making it to dinner time. I've tried the basics like reducing screen brightness and closing apps running in the background, but it doesn't seem to help much. Has anyone else faced this problem? Would love to hear any tips or tricks you guys might have to squeeze a bit more life out of my battery. Is it worth looking into a battery replacement already? Also, I read somewhere that certain apps are notorious for battery drain. Anyone know which ones to watch out for? Let's get a discussion going because I'm sure I'm not the only one dealing with this. 😊
