There is a new type of phone that is going to be released by Spareone.  This cellphone is unique because it runs only on 1 AA battery.  This phone is not supposed to replace a smartphone or your regular cellphone, it is mostly used for emergency calls.  For example, one may  use this phone when traveling or outdoor use.  Some people may not have a chance to charge their phones, and because “The battery life of phones is getting worse and worse,” a person can pop their sim into the Spareone phone and use it (Christian Scheder, the president of SpareOne), emergency calls do not even require a sim card.
