Lagging iPhone after new update.

Is anyone else experiencing issues with the new iOS 18.3.2 lagging their phone? Was fine until this update. Now there are times I go to open say an app and then it’s frozen. I start taping the phone or trying to close the app and nothing works until a good 10sec or so and then will work. Once in the app, I’ll experience more lagging issues like when the qwerty keyboard is coming up or it appears but then you tap any letter and it won’t work.

I’m also experiencing issues when trying to ‘select all’ to copy anything like texts. Why does Apple always bring an update to try fix an issue that was never broken. I have been a die hard fan of iPhone from the day they were released. Looks like I’ll be using my business phone, the s24, which has just sat on my draw since new, diverting text and phone calls to that number over to my personal number. Going to be a full time used one now. Over iPhone and the constant issues.

It has nothing to do with storage. It was fine until the update a few days ago.

Troubleshooting a Lagging iPhone:

System resources a likely being swallowed up, so to speak. So, start with clearing space. Try the following:


I. Cool Down the iPhone:

For a few hours, perform the following...

  • Power Off: the iPhone for a bit
  • Unplug: any Cables
  • Place it Atop: Laptop Cooler
  • Keep it in: an open space
  • Keep it Out of: direct sunlight


II. Clear Space:

If storage is taken up, then it can overheat, leading to lagging. Caches can increase after an update —and it’s happens to me. So, see about clearing space:

Why?:

Usually because they don’t receive enough feedback on it. Question is: "Just how many people have actually reported this to Apple?"


Report this to Apple...

So, do your Part: Provide Apple with feedback on this, letting them know about this issue.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.

  1. Go Here: Feedback - iPhone - Apple
  2. Select: "Bug Report" for the "Feedback Type"
  3. Comment: that this all began after installing an update. Include the URL of this thread
  4. Proceed from there as necessary

One other thing to check is the condition of the battery on your iPhone 13 Pro Max.


You may have a poor battery condition which cannot provide sufficient power for peak performance. What is the Battery Health of your iPhone? Open Settings ➡️ Battery ➡️ Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance. If your battery's Maximum Capacity shows a value of 80% or less, then it has gone through its lifecycle and therefore should be replaced, according to Apple.
