I have a 2012 MBA as well. The battery is still doing it, at 510 cycles now. In your case try the SMC reset to fix that problem. If you hold the "alt" key then click on the battery, it will give you some information including what is consuming it. If you open the Activity Monitor in your Utility folder, then click on the Energy tab, there will be a ...

And don't forget that a cup of ...

You can use the battery from the phone that is not from your provider, but not switch radios. Batteries between models, e.g., iPhone 5, are the same even when the radios are not. Even when radio types are the same, e.g., GSM vs GSM, the operating frequencies, etc., often aren't. Other pieces, such as screen glass, case, screen layers and the like are also ...
