But you are better off with a new phone.
Thanks for the input.
It's not the battery, since we swapped batteries and her phone is still dying with my battery, and my phone's working find with hers.
A complete wipe and fresh install is something I haven't tried yet, but I agree a phone swap would be quicker/easier. The VZ store is two blocks from my office.
