iPhone 12 is so slow

Without traces, it's hard to know what precisely is going on.

One thing I do know is 6th Generation Airport Extremes did have some heating issues late in their lives so it may be they are overheating on long transfers because their internal fans have failed. I bought two for relatives back then and each has had to replace them due to issues; when you notice the transfers have stopped, the LED on the front doesn't change from green to orange, does it?

I’m having the same issue with my 12. It’s Unbelievably slow. I can’t tell you how many times I’d like to throw it across the room just waiting for a photo to load on Instagram. Streaming is constantly being interrupted. I’ve been on the phone with AppleCare+3 times and they can’t offer any suggestions. I would pay $1000 to have my XS back.

Okay , so I just toggled off bold text and my web pages are loading faster. I’m curious if other people here on the forum also have bold text initiated. Time will tell throughout the day if this will fix the iPhone 12 issue with being slow.

Note that private addresses should have nothing to do with speed for any well-designed router.

Once the connection is made, whether the address is a "private" one or not literally makes zero difference.

Indeed, it makes zero difference on either Apple or Ubiquiti wireless access points.

Where I can see this making a difference is on systems that differentiate between "known" and guest devices, with guest devices being shuffled off to a low bandwidth slow subnet.

Just a reminder: If "turning off private address" solves any problems for you, your Wi-Fi router or network configuration is broken.

There is literally nothing that using a private address does that should slow down anything unless your network is doing something very funky.

If you have an issue with 5G, contact your cellular carrier.

5G is a carrier function; Apple has nothing to do with it.

Quite honestly as with past cellular networks the way 5G has been advertised to the public has little to do with how it actually functions in most circumstances.

You say you don’t use it anyway, but if a private WiFi address has any negative consequence whatsoever, it’s because the WiFi network and/or router were designed specifically to do so or were poorly implemented. There is literally nothing about a private WiFi address that can slow anything down unless a network is making improper assumptions or unless it is programmed to apportion bandwidth differently between known and guest devices.

I agree. I think I would kill to have my XS back. Now I’m just waiting until Apple lets me trade in the12. I’ll go back to ANY older phone.

Sell it on a site like eBay and purchase a new phone; you'll get more than a trade-in would be.

It's not painfully slow; in fact it's not slow at all, it's blazingly fast compared to past iPhones, even the iPhone 11 Pro Max.

If it's been fewer than14 days, return it for a refund and get an Android if you feel it better suits your needs.

No the iPhone is slow. I’m on my second i12 pro max in two months. Been on the phone with over 20 techs about 4-6 hrs a day for about 5 days a week for about the first month and 2-3 hrs a days for about 3 days a week until now. Had parts replaced on the replacement I was sent just 28 days after I purchased a brand new one. New touch screen and one week later the touch screen is bad again. I still have slow problems even when I’m getting 150-800 mbps internet speeds. Software updates, network resets, hard resets, carrier support and apple support can’t make this device worth $1600. Can’t even turn the phone off sometimes.

the iPhone 12 is a nice looking paper weight

Mine is also the same i thought it was my WiFi but my iPhone X is still connected and that is also super fast , every time I load a webpage I’m waiting ages for it to load on WiFi

Slower than my iPhone 7. 5G feels slower than 3G

If you are finding 5G speeds to be low, please contact your cellular carrier.

As mentioned previously, your next step is to find out what about your network is handling traffic incorrectly that a private Wi-Fi address makes any difference whatsoever.

Of course, VPNs slow down all network operations as all your network requests are intercepted, encrypted and run through a completely different server.
