iPhone 12 is so slow

iPhone 12 pro max same issue. Running 14.2.1. So annoying! My daughter’s iPod touch will load quickly, husband’s iPhone 8 loads quickly, other daughter’s iPhone 6s loads quickly, I get network errors and I’m left waiting. I tried disconnecting WiFi and running only cellular, but why???!! BTW my last phone did this same thing, so maybe it’s an issue with my profile backup???

Have you tried a Speedtest? I'm just curious if you are seeing slower speeds there as compared to your iPad.

These issues could be due to a variety of reasons, from Safari to DNS issues, so it would be best to find out where the theoretical slowdowns exist.

I know people hate to hear "I'm not seeing them…" but I'm not, so it would be most useful to track down where in the process things may be going awry.

Note that just loading a web page requires about six different things to work together, and an issue may be occurring in any of them.

Note also, the very first thing any of you experiencing this issue should do is notify Apple Support directly:

Contact - Official Apple Support

They are the ones who could notify software engineering of an issue; Apple does not read these forums except to monitor for adherence to the Terms of Use.

We are just fellow Apple users here, and as such we don't have the power to fix anything.

its unclear if you are referring to extremely low battery life or slow wifi, if it is the wifi, the iphone 12 uses a very new wifi protocol that you can turn off if it slows down your system.

1. Go to Settings> Wifi (connect to your network and press the i in the circle)
2. Make sure "Private address" is toggled off (it will probably be automatically enabled).
3. Also make sure low data mode is off (it should ask you to turn this off if you start a big download so you can probably keep it on).

if your battery is dying in 30 mins. of normal use, take it to the apple store or call support. Its probably a battery defect.

Turn a private address off or on for a network

1. Open the Settings app, then tap Wi-Fi.
2. Tap the information button next to a network.
3. Tap Private Address. If your device joined the network without using a private address, a privacy warning will explain why.

I have been playing with this issue and discovered that my iPhone 12 was connecting to my slower wifi 2g instead of the 5g wifi connection. I made the iPhone forget the 2g network and connect only to the 5g and the problem is fixed.

Again, note if this solves anything your network is inherently broken.

Nothing about private addresses should slow down anything.

By “inside the i,” they mean tap this in your list of Wi-Fi networks under Settings.

I am also experiencing this internet slow down on my iPhone 12 256gb. Especially when watching YouTube Videos. On 480p I can watch it just fine but 720p or 1080p, it lags and becomes unwatchable. I don’t know why. It’s slow even when using WiFi too.

My iPhone 12 pro after the update 14.2.1 started acting slow yesterday I could not get on any banking apps or and game apps it would load very slowly and when it did open it would be a blank page but my internet was working fine as well and I had full bars

Works great when I turn off WiFi, obviously that is no solution. I thought maybe it was because it was passed over the login and password when I swapped phones- told it to forget my network and then signed in again. Still the same. Our 11 and X still super fast on the WiFi. Is this an issue with the old SIM card?
