I spent days trying to trigger Android’s battery drain alert, but my phone outsmarted me

I was a massive science fiction fan growing up (I still am). I never imagined that one day I’d have a fully functioning computer that could do just about anything in my pocket. That tiny computer does a lot every single day. The fact that it runs on a battery is amazing. Unfortunately, some processes, apps, and usage can kill your battery fast. But if you’re on Android, your phone probably has a hidden feature that will warn you when it happens.
