Ed has an iPhone 7. He's blind and he relies on Siri to do everything he needs. Leo says that the iPhone is a great phone for the blind because of its accessibility features. Ed finds, though, that the battery isn't as strong as it used to be and it dies while he's using it all the time. Leo says that the lithium-ion batteries are rated for 500 charge/discharge cycles, which is about a two-year window. But the good news is, that Apple will replace the battery for $49. Are there alternatives? Leo says that Google's assistant is really good, and with a Samsung device, customers get Bixby, which is an assistant that is designed to operate the phone itself.
