I'm in Walt Disney world. My battery keeps dying. I can only go so far with battery saving tips. What needs to be attached to my phone or in my pocket to have my phone outlast Sting's lovemaking?
You can find tiny portable micro-usb packs at a local store, like a Walmart or Radio Shack, or even Walgreens or CVS. If you had more time, I'd point you to a few online places.
I have plenty of time. No use in getting it this trip
