How to handle iPhone 'Low Battery' pop up during a game

Question

I was wondering how low battery alerts can be handled during a game. I used Cocos2D to make my game. I have the game pause when an interrupt such as a text or a call come in. But what about low battery alerts? Are they the same as other interrupts? It does not seem to be.

Is there any way I can detect when it comes up so that I can pause the game?

Thanks for your replies.

You can set up "battery monitoring" and get an event when this happens. Some links with info:

You know the event you're worried about is when it hits 20%, so I think you can just check for that amount and pause when it happens.

This is perhaps not a perfect solution, as Apple could decide it should happen at 25%, not 20%.

Also, Apple recommends turning this on only when you really need to know. So it should only be activated during gameplay, not on menus that aren't time sensitive.
