It is not like the original (of course, there are none) but at least with this one I fixed the problem it had with fast charging. Another problem that I had and is not fixed by this board is that the device is not recognized when connected with a USB cable to a computer, and it is possible that something inside is broken. The truth is that if there was an original board like this, it would be clearer what the issue is in this case. Other than that, it works fine.. it is easy to replace for someone who is handy, just be careful when opening the back cover so it doesn't break - it needs to be warmed up first.
