Systems and methods for charging a mobile phone and a mobile phone cover

Abstract

A battery in a mobile phone cover may be selectively charged according to a user-selectable parameter. When charged, the battery in the mobile phone cover may be used to charge a battery in a mobile phone.

What is claimed is: 
     
         1 - 32 . (canceled) 
     
     
         33 . A mobile phone accessory, comprising:
 one or more processors configured to selectively couple a battery of a mobile phone cover to a charging interface according to a passthrough charging parameter, wherein the one or more processors are configured to generate a warning if a flow of charge to the charging interface is below a threshold.   
     
     
         34 . The mobile phone accessory according to  claim 33 , wherein the mobile phone cover comprises the charging interface. 
     
     
         35 . The mobile phone accessory according to  claim 33 , wherein the charging interface is configured to be operably coupled to an external power source. 
     
     
         36 . The mobile phone accessory according to  claim 33 , wherein the charging interface is configured to be operably coupled to a battery of the mobile phone, and wherein the charging interface is external to the mobile phone. 
     
     
         37 . The mobile phone accessory according to  claim 33 , wherein a battery of the mobile phone is operably coupled to the battery of the mobile phone cover. 
     
     
         38 . The mobile phone accessory according to  claim 33 , wherein the one or more processors are configured to provide a user interface associated with the passthrough charging parameter. 
     
     
         39 . The mobile phone accessory according to  claim 33 , wherein when the passthrough charging parameter is selected, a battery of the mobile phone is operably coupled to the charging interface and the battery of the mobile phone cover is decoupled from the charging interface. 
     
     
         40 . The mobile phone accessory according to  claim 33 , wherein when the passthrough charging parameter is deselected, a battery of the mobile phone is operably coupled to the charging interface and the battery of the mobile phone cover is operably coupled to the charging interface. 
     
     
         41 . The mobile phone accessory according to  claim 33 , wherein when a flow of charge to the charging interface is below a threshold, the one or more processors are configured to prioritize one of charging the battery of the mobile phone cover and charging a battery of the mobile phone, wherein the prioritization is selectable. 
     
     
         42 . The mobile phone accessory according to  claim 33 , wherein the mobile phone accessory is positioned around a mobile phone. 
     
     
         43 . A mobile phone charger, comprising:
 one or more processors configured to selectively couple a battery of a mobile phone cover to a charging interface according to a passthrough charging parameter, wherein the one or more processors are configured to generate a warning if a flow of charge to the charging interface is below a threshold.   
     
     
         44 . The mobile phone charger according to  claim 43 , wherein the mobile phone cover comprises the charging interface. 
     
     
         45 . The mobile phone charger according to  claim 43 , wherein the charging interface is configured to be operably coupled to an external power source. 
     
     
         46 . The mobile phone charger according to  claim 43 , wherein the charging interface is configured to be operably coupled to a battery of the mobile phone, and wherein the charging interface is external to the mobile phone. 
     
     
         47 . The mobile phone charger according to  claim 43 , wherein a battery of the mobile phone is operably coupled to the battery of the mobile phone cover. 
     
     
         48 . The mobile phone charger according to  claim 43 , wherein the one or more processors are configured to provide a user interface associated with the passthrough charging parameter. 
     
     
         49 . The mobile phone charger according to  claim 43 , wherein when the passthrough charging parameter is selected, a battery of the mobile phone is operably coupled to the charging interface and the battery of the mobile phone cover is decoupled from the charging interface. 
     
     
         50 . The mobile phone charger according to  claim 43 , wherein when the passthrough charging parameter is deselected, a battery of the mobile phone is operably coupled to the charging interface and the battery of the mobile phone cover is operably coupled to the charging interface. 
     
     
         51 . The mobile phone charger according to  claim 43 , wherein when a flow of charge to the charging interface is below a threshold, the one or more processors are configured to prioritize one of charging the battery of the mobile phone cover and charging a battery of the mobile phone, wherein the prioritization is selectable. 
     
     
         52 . The mobile phone charger according to  claim 43 , wherein the mobile phone charger is positioned around a mobile phone.
