您可以尝试以下几种方法：

我个人没有5.1设备但是通过模拟器试了一下

Intent batterySaver = new Intent();

battSaverIntent.setComponent(new ComponentName("com.android.settings", "com.android.settings.Settings$BatterySaverSettingsActivity"));

startActivityForResult(batterySaver, 0);

或用于摘要用法

Intent batterySaver = new Intent(Intent.ACTION_POWER_USAGE_SUMMARY);

startActivity(batterySaver);

对于API级别> 22

startActivityForResult(new Intent(Settings.ACTION_BATTERY_SAVER_SETTINGS), 0);
