It looks like it has nothing to do with 3rd-Party applications and more about iOS itself. Here's an article I found:

<a href="http://www.redmondpie.com/how-ios-9-low-power-mode-for-battery-life-saving-works/" rel="nofollow">http://www.redmondpie.com/how-ios-9-low-power-mode-for-battery-life-saving-works/</a>

Here's another article that seems to confirm it is only for iOS itself (and background processes like downloading, which may effect some apps):
<a href="http://www.idownloadblog.com/2015/06/08/low-power-mode-in-ios-9/" rel="nofollow">http://www.idownloadblog.com/2015/06/08/low-power-mode-in-ios-9/</a>

As far as I'm aware, none of this requires any developer interaction. From Apple's perspective that would be a bad idea, since then developers could essentially choose whether or not to comply, and would make their Low Power mode useless (because many developers would not choose to make their app perform worse)

On a side note, I'm happy that iOS 9 will no longer light up my screen if my device is facedown on a table and I get a notification. If you read, there's a few new power-saving features that do not involve the use of the Low Power mode.

Update for 9.0.2:
I am sorry to say, that the above answer is not correct (anymore). 
When in power mode, apps can't react to push messages anymore, because the corresponding function 

<pre><code>- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
</code></pre>

is not called. 

I wonder how messaging services go around that? 
Has anybody got any clue? 

See also my explicit question - with more details on this matter: 
<a href="https://stackoverflow.com/questions/33144238/ios9-push-battery-saver-mode-didreceiveremotenotification-not-called">IOS9 Push Battery Saver Mode - didReceiveRemoteNotification not called</a>

In the WWDC 2015 keynote, it was mentioned that batteries will last one hour longer, and have a low power state that can extend the battery three more hours.

Do iOS App developers have to do anything for this new feature? Is there something their apps must do (or not do) when in that low battery state?

iOS 9: low energy -> do developers have to prepare for that?

在WWDC 2015的主旨发言中，有人提到电池将持续一个小时以上，并且具有低功率状态，可以将电池再延长三个小时。iOS应用程序开发人员必须为这个新特性做些什么吗？在低电池状态下，他们的应用程序是否必须做些什么？
