If you haven’t updated your Apple iPhone from the 10.x version to the 11.x version of the IOS, currently 11.0.3 at the time of this writing, don’t do it unless you want to find yourself frustrated and starting over.
The 11.x version is wrought with performance bugs and incompatibilities. I gladly update my iPhone almost every time a new version comes out. But this time around, I ended up with an iPhone that was almost useless to me. All it could really do correctly was make and receive phone calls. But the interface became molassesly sluggish, the apps would hang on opening, or crash repeatedly, exiting spontaneously, and clicking on anything took several tries before it would accept the request. On top of all this, my battery life went from a standby time of roughly twenty hours…. to TWO! And it is HOT ALL the TIME! Just to use my phone in the last few weeks, I carried my power adapter with me and plugged it in at ALL times to keep the phone alive for longer than these couple hours at a time.
Of course, I wanted to go back to 10.x. For a time, you could have done that. But Apple has since “unsigned” their earlier IOS versions, and generally do this after a new version has been out a while. A the time I attempted to restore to the earlier IOS version using the recovery feature of the iPhone and iTunes interface, all 10.x versions of the IOS were now unsigned and I was unable to do so.
My only recourse, which surprisingly seems to have worked, was to completely wipe the phone, and documents, files, setting,s networking, and … well… everything, and start with it as if it was brand new. I have installed the core features of software and apps that I need and the phone appears to be behaving itself. That leads me to believe that the trouble may have been one or more of the apps that was installed on the phone possibly messing with the IOS in the background. I suppose as I add more apps, I might stumble on ones that cause issues.
But this is very disturbing to me. I am not a unique case. I have asked everyone that I know that has an iPhone and had gone through the 11.x updates and come to find that the issues, frustrations, and arguments are all the same. I think my issues were more drastic or pronounced than other people. But they all stated that the interface began running sluggishly and the battery life went into the crapper. Furthermore, a Google search results in hundreds, thousands…. millions? … of posts out there all saying the same thing.
How could Apple allow this IOS to go out with such horrific performance issues, without allowing a way back to a working IOS until they can patch the issues? That is not like Apple.
I even joined the 11.1 Beta program that would allow me to install a version of the IOS that is not for the general public. This is the next version you would get, but even this future unreleased version marginally helped. my issues. My Phone was still a broken in the IOS. Again, let it be known that this IS the version of the IOS that I am running on the iPhone right now, and it is behaving but only after the factory refresh I performed. Maybe it isn’t fair to criticize the IOS if the issues I was experiencing ultimately were related to an app. But Apple is so bent on keeping the development of their apps closed and following specific guidelines for development for their platform. I find it hard to believe that one app could have killed the performance and battery life of the iPhone without Apple or the developer discovering this along the way and preventing it to be released into the general public and cause such widespread issues.
Anyway, for what its worth, beware of the 11.x IOS and be prepared to refresh the phone, or hope that APple or the App developers locate the offending issues in the next release.
