    响应于用户在第一显示界面中的第一操作，所述电子设备进入第二省电模式，所述第一显示界面为所述电子设备在进入第二省电模式之前的界面。
  18. 根据权利要求15-17中任一项所述的方法，其特征在于，所述电子设备启动升压电路，包括：
    所述电子设备检测所述电子设备是否包括所述升压电路；
    在确定所述电子设备包括所述升压电路时，所述电子设备启动所述升压电路。
  19. 根据权利要求15-18中任一项所述的方法，其特征在于，所述方法还包括：
    响应于用户的第二操作，所述电子设备关闭所述升压电路并关机。
  20. 根据权利要求19所述的方法，其特征在于，所述方法还包括：
    响应于用户开机的操作，所述电子设备进入所述第二省电模式。
  21. 根据权利要求15-20中任一项所述的方法，其特征在于，所述方法还包括：
    在所述第二省电模式下，所述电子设备检测到电池电量耗尽，所述电子设备关机。
  22. 根据权利要求15-21中任一项所述的方法，其特征在于，所述方法还包括：
    在所述第二省电模式下，所述电子设备检测到所述电池电量提升为第三电量时，所述电子设备关闭所述升压电路，其中，所述第三电量大于所述第二电量。
  23. 根据权利要求15-22中任一项所述的方法，其特征在于，所述第二电量为1％。
  24. 一种电子设备，其特征在于，包括：一个或多个处理器；一个或多个存储器；该一个或多个存储器存储有一个或多个计算机程序，该一个或多个计算机程序包括指令，当该指令被一个或多个处理器执行时，使得如权利要求1-23中任一项所述的省电方法被执行。
  25. 一种计算机可读存储介质，其特征在于，所述计算机可读存储介质中存储有计算机指令，当所述计算机指令在计算机上运行时，使得如权利要求1-23中任一项所述的省电方法被执行。
