例如，mt6580-android6.0，关机充电电流大小修改：
vendor/mediatek/proprietary/bootable/bootloader/lk/target/xxx/include/target/cust_battery.h...#define USB_CHARGER_CURRENTCust_CC_650MA#define AC_CHARGER_CURRENT Cust_CC_800MA
修改开机状态外部充电的方式下电流大小：
kernel-3.18/drivers/misc/mediatek/include/mt-plat/mt6580/include/mach/mt_charging.h...#define USB_CHARGER_CURRENT CHARGE_CURRENT_650_00_MA //usb充电电流#define AC_CHARGER_CURRENTCHARGE_CURRENT_800_00_MA //直流充电电流#define NON_STD_AC_CHARGER_CURRENTCHARGE_CURRENT_1600_00_MA //外部第三方充电器电流
各温度下对应电量与充电电电流：
kernel-3.18/drivers/misc/mediatek/include/mt-plat/mt6580/include/mach/mt_battery_meter.h...//各温度下电量大小#define Q_MAX_POS_50 5500#define Q_MAX_POS_25 6000#define Q_MAX_POS_0 5800#define Q_MAX_NEG_10 6000//各温度下充电最大电流，这里表示1600ma#define Q_MAX_POS_50_H_CURRENT 1600#define Q_MAX_POS_25_H_CURRENT 1600#define Q_MAX_POS_0_H_CURRENT 1600#define Q_MAX_NEG_10_H_CURRENT 1600
