Some adapters don't supply enough current to run the phone (the
most demanding use is having a conversation on the phone, or perhaps
long data transfers, both of which use the radio continuously). If
your battery is entirely discharged, you might have to charge it
(hopefully powered off, or at least with the screen off and no call
active) for maybe 10 minutes before making a call, and you could
still run out of juice during a long call.
I would hope that if the adapter did supply more than enough current
to run the phone, that higher voltages wouldn't damage the phone.
I believe one possible failure mode of a battery is that it
open-circuits (effectively, "it isn't there", so it won't supply
current nor take charging current) and it would be bad if that
failure also damaged the phone, it's a serious problem. This assumes
you're using an adapter approved for that phone, and that the
manufacturer cares about quality, as distinguished from including
as much lead as possible.
