iPhone 5s going unresponsive

[ghanwani]

I have an iPhone 5s running iOS 9.0.2. For the last couple of days the phone has been going unresponsive--the only thing that works is double clicking the home button and sometimes the ability to terminate apps that show up as a result of that double-clicking. My phone also feels very slow to use.

Is the unresponsiveness due to a bug or failing hardware?

Is there any information on how to optimize iOS 9 on the 5s, say by turning off certain features that consume CPU and are running by default?

Another issue I've been having is that when I use Siri to look something up, if I'm lucky to get it to recognize what I'm asking, I still get an error of the type "Siri is unable to determine your current location" and it aborts.

Didn't experience any of this with iOS 8.

Before I gave my 5s to my wife, 9.0.2 was pretty much stable. After I wiped the 5s and restored her backup from iTunes, a few days later my wife was complaining of the phone freezing. I'm saying it's the Facebook app as its not hardware nor iOS 9.0.2.

First reset all settings. If this doesn't work then restore your phone as new. That way you'll eliminate the software issues. And most probably your phone will go back to being responsive.

I don't use Facebook, so we can pretty much rule that one out, but it may well be some other app that I use.

Of course before anything else you should do a hard reset holding home and lock button till the Apple logo appears -if you haven't done that already.

I haven't tried this one yet. Perhaps I will give it a shot

This one I have already done and is what I typically do to get things running again.
