What is あっちゃう in this sentence?


My friend sent me an email saying her mobile phone is having problems.
Specifically, she said this:

> 携帯{けいたい}の電池{でんち}が電話{でんわ}すると5分{ふん}でなくあっちゃうようになった

I get the overall meaning, which is that when she makes a call, the battery
runs out of power after only 5 minutes.

However I can't parse `でなくあっちゃうようになった`, specifically the `あっちゃう` part.

What is going on here, and how is it different from
`携帯{けいたい}の電池{でんち}が電話{でんわ}すると5分{ふん}でなくなる`?

_(Please no overly technical linguistic terms. Thanks!)_




As Flaw comments, this is a typo of `5分でなくなっちゃう`, which is a contracted form
of `5分でなくなってしまう` 'unfortunately, runs out in five minutes'.
