What is あっちゃう in this sentence? [closed]

Question

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!)

Answer 1

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'.
