battery life tips for smartphones?

So, I've been noticing my phone's battery life draining faster than usual. It's a bit frustrating, especially when you're out and about and suddenly find yourself in the red zone 😅. I used to have this old phone that could last for days (okay, maybe not days, but it felt like it!). Anyway, I thought it might be fun to share some tips or tricks that have worked for you guys. I've tried the usual stuff like reducing screen brightness and closing background apps, but I'm curious if there's anything else out there. Someone once told me to turn off location services when not needed, which helped a bit. Has anyone else tried battery-saving apps or maybe even those portable chargers? Would love to hear your thoughts or any other hacks you've discovered! 📱🔋
