Can we talk about how my phone's battery died right when I needed directions?
I was driving to a new client's office in Phoenix yesterday and my phone was at 15%. I figured I had enough juice for the 20 minute trip. The map app drained it to zero before I even got off the freeway. I had to pull into a gas station, buy a cheap charger for $12, and wait 10 minutes just to get enough power to turn it back on. What's a good backup plan for when your main device fails like that?
