Does your iPhone have a good or bad A9 CPU?

Really misleading title, as the difference appears to mostly be about battery life. Now Engadget is claiming huge differences of up to 2 hours better performance with the TSMC chip phones, but speed differences are unknown. Interesting stuff.

Update: I didn’t realize at the time of posting that this was a user submitted post. Most of the data here is from Reddit. While not the best source, there does seem to be some anecdotal evidence to support the claim. This is going to be interesting as people test it more.
