I ended up with this function.

Note: It's not equal to isPowerSaveMode(). It's more like isRunningOutOfPower() or couldBePowerSaveMode()

It checks if the SDK >= 21 then isPowerSaveMode function is available. if not, then check if the GPS mode is not HIGH_ACCURACY and battery level is less than 15% then it "could be" powerSaveMode.

public static boolean couldBePowerSaveMode(Context context) {
PowerManager powerManager = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
  if (powerManager != null) {
    return powerManager.isPowerSaveMode();
  }
}

if (getLocationMode(context) != Settings.Secure.LOCATION_MODE_HIGH_ACCURACY) {
  return getBatteryPercentage(context) <= 15;
}
return getBatteryPercentage(context) <= 15;

}

Check Google Developer: PowerManager

In the left top, you can change API level.

As you can see, isPowerSaveMode(), is added in API 21(Lollipop).

So it won't work on older devices.

On Mobiles with an Android version below 5.0 (Lollipop) the power_saving mode is different for each manufactor. However if your target version is 5.0 and higher you can use the PowerManager as descripted in Android Developer

There are exceptions above 5.0, still. E.g.: https://stackoverflow.com/a/35635833/1293492 – Tamás Bolvári Sep 21 '18 at 22:36

Hmm.This is check high acurary mode in GPS. This is check:

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    try {
                        if (getLocationMode(getApplicationContext()) != 3) {
                            tvmessage.setText("Please turn on GPS high Acurary");
                            btcancel_Dialog.setText("OK");
                            btcancel_Dialog.setOnClickListener(new OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
                                    dlg.dismiss();
                                }
                            });
                            dlg.show();
                        } else {

                            Intent intentvitri = new Intent(customer_textReport.this, CustomerGetLocation.class);
                            startActivityForResult(intentvitri, 111);
                        }
                    } catch (Settings.SettingNotFoundException e) {
                        e.printStackTrace();
                    }
                }

and method getLocationMode return mode of GPS:

 private int getLocationMode(Context context) throws Settings.SettingNotFoundException {
    return Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);

}

Try this (ready for copy/paste):

/**
 * Checks if device is in power save mode. For older versions that do not support this API, returns false.
 * @return true if it is, false otherwise.
 */
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private static boolean isPowerSaveMode(Context context)
{
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
    {
        PowerManager powerManager = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        return powerManager.isPowerSaveMode();
    }

    // For older versions, we just say that device is not in power save mode
    return false;
}
