You can schedule an appointment at your Apple Store Genius Bar

Threatening to "make noise" in other ways won't get anyone here much.

Oh yes! I have just remembered something and thank you @lobsterghost1 for reminding me. I remember reading on Apple’s website and on Bell’s website both concerning the iPhone 12 and 5G connectivity, and they said that you would need to request from your carrier a new SIM card that will be able to run 5G. I am not an expert on SIM cards or on 5G so I’m not sure how it works (although I kind of remember a similar thing happened when there was a switch from 3G to 4G). Whether or not your device is running 5G, if the SIM card is incapable of that feature, it will cause issues with the phone, this is because if the device detects a SIM card and sees the carrier validity (again, not sure how it works), it will keep checking for 5G signals wherever you may be, and if the SIM Card is incompatible, this is what causes the issues. This explains why there are reports that show a very long battery life without a SIM Card as compared to with SIM Card. Simply call or got to your carrier, inform them that you have gotten the iPhone 12, a 5G capable device, and request a new SIM Card as per your plan. Another option I’ve heard of, although unsure if it’s the same case with the iPhone 12, is to use the eSim provided by Apple with your device and somehow there is a way to work it with a new plan or transfer over your current plan (not sure about the latter, but definitely see if you can anything about it).

So, the problem turned out to be the SIM CARD.

This is not the website I initially found, but it is also helpful.

Use 5G with your iPhone - Apple Support

We’re just fellow users here; you need to contact Apple Support directly:

Also, your fingers are not burning up; the phone will shut itself down well before it becomes warm enough to cause any actual injury let alone “go up in flames.”

Overheating 44Centigrade just charging or checking mails most background activities already stopped etc. Hot enough to get tour ear burnt when you talk on the phone.

Do you have proof of that 44ºC from a thermometer?

Millions of people do not have this problem, so if you want to work to solve it, please create a new thread and people will be happy to work with you on it, or you can contact Apple Support directly:

People have different tolerances to heat and cold. Some experience discomfort holding a slice of pizza from the oven while many people who work in plastic injection molding facilities can handle pieces fresh from the mold.

Regardless, the iPhone does have internal sensors which will turn it off to cool should it get too hot, long before it reaches a temperature where it could cause injury.

Keeping iPhone, iPad, and iPod touch within acceptable operating temperatures - Apple Support

Don’t worry about the temperatures, the phone will shut itself down if it gets too hot.

It’s also designed to charge quickly with the 20w power adapter - a feature called “fast charging.”

Fast charge your iPhone - Apple Support

When charging, be sure to keep your phone in an open and well-ventilated area, not under a pillow.

It’s important to keep iPhone, the charging cable, the power adapter, and any wireless charger in a well-ventilated area when in use or charging.

Important safety information for iPhone - Apple Support

Then tell Apple that. You haven't done so here on this user to user only forum. Schedule an appointment at your Apple Store Genius Bar or use the Get Support button at the top of this page or use this link to let Apple know you have an issue --> Feedback - iPhone - Apple

Complaining here to just other users, is pointless and gets you nothing. Also to suggest you're waiting for Apple to do something, when the vast majority of users have no overheating issues on their iPhone 12 is pretty difficult. It is NOT a universal issue and seems to only effect a small number of users (when you factor in the millions upon millions of iPhone 12's sold around the world). Users who have an issue need to work with Apple on their issue and stop sitting back waiting for Apple to do some mythical thing.

What's the temperature when this occurs?

The iPhone 12 Pro Max is designed to operate in temperatures of 32° to 95° F (0° to 35° C).

So are the Samsung Galaxy S21 Ultra and Google Pixel 5.

The documentation for the Pixel 5 also explicitly states:

Use of your Pixel 5 in certain modes, such as gaming, taking videos, using a flashlight setting, or VR, can cause it to generate more heat than it would under normal operating conditions. This may cause your Pixel 5 to operate in a reduced-power mode or temporarily shut down. Use extra care when operating the device in these modes.

You don’t need your SIM card to do a backup (that you would restore from on the new phone.)

I've had a 12 Pro Max since November and it never even gets noticeably warm after using it for hours, but I'm also not doing something like running a full graphic online game.

Battery health is a calculation performed based upon battery chemistry and newer batteries have more accurate battery life sensors than old phones.

For example, if you have a car whose gas gauge reads full until it's ¾ full, that doesn't mean it gets better mileage than a car whose gas gauge accurately shows levels between full and ¾.

Note Apple will replace your battery for free if the health drops to below 80% within your one year factory warranty.

If you hold your breath waiting for a recall/replacement, you'll turn blue and pass away.

I've now had my 12 Pro Max for 2 days. NO unusual warmth at all. The battery life is excellent. It fully indexed my multiple thousands of photos while I slept last night and she's been running cool as can be all day, with streaming music, while doing assorted other activities.

Have you gone to Settings > Battery and looked at what is taking the most charge. I suspect you have something running in the background which you may not be aware is.

Also, have you Force Restarted the phone since you got it? If you haven't, you should do so immediately. Here's how:

• Press and quickly release volume up button
• Then press and quickly release volume down button
• Then press and keep holding the side power button (keep holding past the swipe to power off) until you see the Apple Logo, then let go

Lastly, make sure you have updated to iOS 14.2 on your new phone.

I have the same issue ... on the iPhone 12 Pro Max 256GB - Canadian version.

• It seems to happen while gaming Candy Crush
• Had the phone since Nov 14 and noticed the problem a couple of days later.
• Noticed that it is the upper half of the phone that felt very warm.
• Noticed that it got very warm after 10-15 minutes on Candy Crush.
• Same Candy Crush gaming did not have a problem on the old iPhone (iPhone XS Max).
• In contact with tech support and they suggested that I manually turn off the phone and wait 10-15 minutes. Then turn it back on and see if Candy Crush produces the same problem. If so, contact them again.
• Will report back any new developments.

Went through Apple Support and they only assisted me in:

1. Turning iPhone off and turning it back on after a few minutes. Didn’t resolve the problem.
2. Backing up and the restoring the iPhone. Didn’t resolve the problem.
3. Finally got a Genius Bar appointment and they did a diagnostic while linked to their store Wi-Fi - diagnostic report showed no thermal warnings. Didn’t resolve the problem obviously.

Have to wonder where’s the problem STILL!?
