The Evidence
My phone dies at exactly 2% battery. Always. Even if it was at 50% five minutes ago. The phone knows when you NEED it to last. That's when it dies.
Also, have you noticed how your phone gets heavier when you're trying to take a photo? It's trying to make you drop it. They team up with gravity.
Consumer Reports
I filed a complaint with the phone company. They said it's "user error." User error?! My phone literally threw itself into the toilet. USER ERROR? I THINK NOT!
