But are you really going to access your Facebook account and or start Twittering with your smart phone and hope that someone knows and or cares about your predicament or are you going to call the Emergency Services such as the Police, Mountain Rescue or Coast Guard? If battery power or cell service range is spotty then an SMS to your Twitter page might be worthwhile, but would you attempt to call the emergency services first and risk the last of the battery power on the phone?

Opening a browser page to login into the Facebook account on the phone will probably draw more power on the smartphone than making a voice call or sending an SMS.
