Abstract: The present invention discloses a low-power startup method and a user equipment. The method includes: running, by a user equipment UE, a first subprogram in a boot load program bootloader, so as to determine whether the UE is charged through a universal serial bus interface USB; if the UE is charged through the USB and battery power is lower than a starting threshold, initializing, by the UE, the USB; when the USB successfully enumerates the UE, running, by the UE, a second subprogram in the bootloader to initialize an off-chip random memory in the UE; running, by the UE, a third subprogram in the bootloader to read a system mirror from an off-chip flash memory in the UE and load the system mirror to the off-chip random memory; and running, by the UE, the system mirror to complete a startup.

Abstract translation: 本发明公开了一种低功率启动方法和用户设备。 该方法包括：由用户设备UE运行引导加载程序引导加载程序中的第一子程序，以便确定UE是否通过通用串行总线接口USB进行充电; 如果UE通过USB充电并且电池电力低于起始阈值，则由UE初始化USB; 当USB成功地枚举UE时，由UE运行引导加载器中的第二子程序以初始化UE中的片外随机存储器; 由UE运行引导加载器中的第三子程序以从UE中的片外闪存读取系统镜像，并将系统镜像加载到片外随机存储器; 并由UE运行系统镜像来完成启动。
