## Obtaining and Setting i18n Information
The system provides APIs to configure information such as the system language, preferred language, country or region, 24-hour clock, and local digit switch.
The following table lists the APIs used to configure information such as the system language, preferred language, country or region, 24-hour clock, and use of local digits.

# Power Subsystem Changelog
## cl.powermgr.1 CommonEventBatteryChangedCode API Change
Changed the **CommonEventBatteryChangedCode** enum class in [@ohos.batteryInfo](../../../application-dev/reference/apis/js-apis-battery-info.md) as follows:
- Changed the class name to **CommonEventBatteryChangedKey**.
- Deleted **EXTRA_MAX_CURRENT**, **EXTRA_MAX_VOLTAGE**, and **EXTRA_CHARGE_COUNTER**.
- Changed the enum value type from numeric to string.
#### Change Impact
The JS API needs to be adapted for applications developed based on earlier versions. Otherwise, relevant functions will be affected.
#### Key API/Component Changes
Before change:
| Name | Value | Description |
| -------------------- | ---- | -------------------------------------------------- |
| EXTRA_SOC | 0 | Remaining battery level in percentage. |
| EXTRA_VOLTAGE | 1 | Battery voltage of the device. |
| EXTRA_TEMPERATURE | 2 | Battery temperature of the device. |
| EXTRA_HEALTH_STATE | 3 | Battery health status of the device. |
| EXTRA_PLUGGED_TYPE | 4 | Type of the charger connected to the device. |
| EXTRA_MAX_CURRENT | 5 | Maximum battery current of the device. |
| EXTRA_MAX_VOLTAGE | 6 | Maximum battery voltage of the device. |
| EXTRA_CHARGE_STATE | 7 | Battery charging status of the device. |
| EXTRA_CHARGE_COUNTER | 8 | Number of battery charging times of the device. |
| EXTRA_PRESENT | 9 | Whether the battery is supported by the device or installed.|
| EXTRA_TECHNOLOGY | 10 | Battery technology of the device. |
| EXTRA_CAPACITY_LEVEL | 11 | Battery level of the device. |
After change:
| Name | Value | Description |
| -------------------- | --------------- | -------------------------------------------------- |
| EXTRA_SOC | "soc" | Remaining battery level in percentage. |
| EXTRA_CHARGE_STATE | "chargeState" | Battery charging status of the device. |
| EXTRA_HEALTH_STATE | "healthState" | Battery health status of the device. |
| EXTRA_PLUGGED_TYPE | "pluggedType" | Type of the charger connected to the device. |
| EXTRA_VOLTAGE | "voltage" | Battery voltage of the device. |
| EXTRA_TECHNOLOGY | "technology" | Battery technology of the device. |
| EXTRA_TEMPERATURE | "temperature" | Battery temperature of the device. |
| EXTRA_PRESENT | "present" | Whether the battery is supported by the device or installed.|
| EXTRA_CAPACITY_LEVEL | "capacityLevel" | Battery level of the device. |
#### Adaptation Guide
For details, see the API reference of the [@ohos.batteryInfo](../../../application-dev/reference/apis/js-apis-battery-info.md) API.
## cl.powermgr.2 estimatedRemainingChargeTime API Change
Changed the **estimatedRemainingChargeTime** API in [@ohos.batteryInfo](../../../application-dev/reference/apis/js-apis-battery-info.md) to a system API.
#### Change Impact
The JS API needs to be adapted for applications developed based on earlier versions. Otherwise, relevant functions will be affected.
#### Adaptation Guide
For details, see the API reference of the [@ohos.batteryInfo](../../../application-dev/reference/apis/js-apis-battery-info.md) API.
## cl.powermgr.3 System Common Event Behavior Change
The following common events are provided in the battery information through [@ohos.commonEventManager (common event module)](https://gitee.com/openharmony/docs/blob/master/en/application-dev/reference/apis/js-apis-commonEventManager.md):
- COMMON_EVENT_BATTERY_LOW: common event for low battery level. It includes the remaining battery in percentage.
- COMMON_EVENT_BATTERY_OKAY: common event for normal battery level. It includes the remaining battery in percentage.
- COMMON_EVENT_POWER_CONNECTED: common event for connection to an external power supply. It includes the type of the power supply to which the device is connected.
- COMMON_EVENT_POWER_DISCONNECTED: common event for disconnection from an external power supply. It includes the type of the power supply from which the device is disconnected.
- COMMON_EVENT_CHARGING: common event for starting of battery charging. It includes the battery charging status.
- COMMON_EVENT_DISCHARGING: common event for ending of battery charging. It includes the battery charging status.
Changed the method of obtaining data from common events from **CommonEventData.data** to **CommonEventData.code**.
#### Change Impact
The application developed based on earlier versions needs to adapt the method for obtaining common events in the battery information. Otherwise, the original service logic will be affected.
#### Adaptation Guide
For details, see the API reference of the [@ohos.commonEventManager (Common Event Manager)](../../../application-dev/reference/apis/js-apis-commonEventManager.md) API.
