This may be a dumb question, but when the battery in someone's dies and you call them, will it still ring or will it just go straight to voicemail?
Ringing takes power, so no.
voicemail. It switches off.
Erm I tried it once, the universe ceased to exist for 5 seconds, after that it went to voicemail
Voicemail. Why do you ask? Just trying to reassure yourself that your girlfriend isn't picking up because her battery is dead not because she doesn't want to talk to you?
