Because my iPhone 13 is lowering the performance in iOS 18.4

I have a semi-new iPhone 13. It has no unknown parts, nor does any warning appear in settings. I have already restored it several times (as new), I have iOS updated to the latest version and more than 90 GB of free storage.

The problem I have is that whenever I open a game, the cell phone gives me lag at the beginning, whatever the game is, even light titles like Geometry Dash or Geometry Dash SubZero. Also sometimes, the system crashes a little when I slide fast, although that is removed when restarting.

I already did all of the following:

• Factory reset from iPhone.

• Close all apps in the background.

• Review of battery usage (there are no apps consuming a lot).

• Activate "Reduce movement" in accessibility.

• Latest version of iOS installed.

• I have a lot of free space (more than 90 GB).

• The battery is at 100% health.

• I haven't seen bugs like restarts or problems with the touch screen, except for those lags when starting games or when I swipe very fast.

I don't have access to a computer to do a DFU restore, so for now I can't do that.

Do you think this is a hardware failure or an iOS error? I am interested in knowing if anyone else has gone through the same thing and if this could be solved with a future update.

I have a semi-new iPhone 13.

Please define "semi-new".

The iPhone 13 was discontinued by Apple in September 2024. So, if your iPhone 13 is really "new", it has been sitting in a warehouse somewhere for 6+ months, perhaps much longer. This would not have been good for the battery at all.

So, if your iPhone 13 is not really "new", it is used, perhaps as much as 3+ years or more.

I bought the iPhone 13 in a store that's what I mean with *Semi-New* The iPhone came without its box only the device something like *Refurbished* But I'm surprised that in the model number it starts with *M* What says that the iPhone was bought new in 2022

What says that the iPhone was bought new in 2022

Then, you know that your iPhone is used and it is at least 2+ years old. It probably has a new battery though.

The warranty probably expired long ago. What does it say about the Warranty Coverage if you check Settings > General > About on your iPhone 13?

Do you think this is a hardware failure or an iOS error?

I do not think that it is a hardware failure or an iOS error. I think that the phone is behaving normally. But, you should make an appointment at the Apple Store to get the iPhone checked and tested.

Yes, the device behaves well but I don't understand those failures and I think it's an iOS problem because I enter for example to settings and I touch an adjustment and I want to go back quickly again sometimes the click I gave is not registered, I thought it was a problem on the screen but the screen is perfect it has no scratches or anything besides that it presents lag as I told you, what I missed is that I already reset my iPhone like 3 times

There is nothing more that you can do at this point.

Please let us know the results of the checks and tests that Apple Service will run when you take the phone in for service.

The problem is that in my country there is no Apple technical service, you sell the devices but there is no specific technical place
