1. Demo 下载

2. 电池温度
// 当前电池温度
import static android.os.BatteryManager.EXTRA_TEMPERATURE;
private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (null == intent) {
return;
}
String action = intent.getAction();
if (Intent.ACTION_BATTERY_CHANGED.equals(action)) {
// 电池温度
int temperature = intent.getIntExtra(EXTRA_TEMPERATURE, -1);
3. 电池健康状态-温度过低
private String getHealth(int health) {
String result = getString(R.string.battery_health_unknow);
switch (health) {
case BATTERY_HEALTH_UNKNOWN:// 未知
break;
case BATTERY_HEALTH_GOOD:// 良好
result = getString(R.string.battery_health_good);
break;
case BATTERY_HEALTH_OVERHEAT:// 过热
result = getString(R.string.battery_health_overheat);
break;
case BATTERY_HEALTH_DEAD: // 没电
result = getString(R.string.battery_health_dead);
break;
case BATTERY_HEALTH_UNSPECIFIED_FAILURE: // 未知错误
result = getString(R.string.battery_health_unspecified_failure);
break;
case BATTERY_HEALTH_OVER_VOLTAGE:// 过电压
result = getString(R.string.battery_health_over_voltage);
break;
case BATTERY_HEALTH_COLD: // 温度过低
result = getString(R.string.battery_health_cold);
break;
}
return result;
}
底层上报数值如下
enum {
BATTERY_HEALTH_UNKNOWN = 1,
BATTERY_HEALTH_GOOD = 2,
BATTERY_HEALTH_OVERHEAT = 3,
BATTERY_HEALTH_DEAD = 4,
BATTERY_HEALTH_OVER_VOLTAGE = 5,
BATTERY_HEALTH_UNSPECIFIED_FAILURE = 6,
BATTERY_HEALTH_COLD = 7,
};
4.adb shell 查看电池温度
adb shell cat /sys/devices/platform/battery/Battery_Temperature
5. adb shell 设置电池温度
adb shell “echo 55 > /sys/devices/platform/battery/Battery_Temperature”
这里可以设置一些极限温度，手机一般会报高温和低温警告
