5 - 30 minutos
The iPhone battery would only keep a charge for 30 minutes or so. I bought the hard drive to use in place of the 160 gb hd that came in the Mac mini.
The iPhone took about 20minutes to repair. It was very simple to change it out. The hard drive I copied my Mac system on and installed it onto my mini. The repair was smooth and quick to do excluding the 4 hours it took to load/copy everything from my original hard drive.
Why replace the product when you can fixit.
