IMAGINE this: You are still pumped up after watching a music concert with friends. While waiting for the crowd to thin out, you excitedly scroll through Instagram again and the gazillion selfies and HD videos you took. What a night.
You head to the exit, part ways with your friends, and whip out your smartphone again to book a ride home. The dreaded warning flashed - '10 percent battery life remaining.' You hurriedly try to book, but with many others booking their rides, you are unable to. Meanwhile, your battery is draining. Finally, it sounds out the last warning, and dies. You are stranded and on your own. Without a ride home. What a night.
