It's a hassle to keep multiple devices charged. If 80% of people have the mental bandwidth to keep their phone charged daily, I'd say less than 50% would be able to do the same for 2 devices. Part of the reason people like tablets as a second device is that you can turn off the screen and it'll maintain a charge for several days. If it had to be charged as frequently as a phone, people would just stick to their phone.
