Iphone 15pro max temperature error after ios27

iPhone needs to cool down, warning:-

You need to identify the exact pattern and circumstances under which the warning or problem appears, rather than treating each occurrence as an isolated incident. Note what was happening on the iPhone at the time, including:

• Which app was running when the issue occurred — Safari, YouTube, WhatsApp, Instagram, Maps, streaming apps, etc.
• Whether the iPhone was connected through Wi-Fi or Cellular Data.
• If using cellular data, whether you were on your home network, another network, or roaming.
• The cellular signal strength at the time and whether the phone was switching between 5G, 4G/LTE, or different bands.
• Whether the problem occurs during ordinary browsing or only when an app is transferring a large amount of data.
• Whether the iPhone becomes noticeably warm or hot immediately before the network connection drops.
• How long the cellular connection remains unavailable and whether it automatically reconnects afterwards.
• Whether the problem affects only internet connectivity or also interrupts normal cellular voice calls.
• Whether the same behaviour occurs in different locations and with different Wi-Fi networks.

The most important clue is the relationship between the heating and the loss of cellular connectivity. If the iPhone consistently starts heating when mobile data or internet-intensive applications are being used, and at approximately the same time the cellular connection completely drops for several seconds, this should not automatically be dismissed as ordinary iPhone heating.

That pattern could point toward a cellular modem, radio, antenna, network-handling, or carrier-related issue, rather than simply the device becoming warm because of processor activity. Internet-heavy applications may increase cellular radio activity and data transmission, potentially exposing a problem that does not appear during light or offline use.

Therefore, the objective is not merely to establish that “the iPhone gets hot.” The objective is to determine whether there is a repeatable sequence such as:

Mobile Data/Heavy Internet Activity → Increased Device Heating → Cellular Signal/Connection Drops → Internet/Calls Interrupted → Connection Recovers

If this sequence can be reproduced consistently, it provides much stronger evidence of a network/modem-related problem and gives Apple Support or an authorised service provider something specific to investigate, rather than simply recording the symptom as normal device heating.

Your iPhone has exceeded the maximum operating temperature per its specifications. That is a hardware failure, unless you left the phone in direct sunlight or a really hot location.

Wait for it to cool down, but if it repeats contact Apple to discuss repair options:iPhone Repair and Service - Apple Support

it's a known issue of ios 27 (as of community, idk about apple tho) on iphone 14 and 15 series, my iphone 14 shows the false temperature warning even though the phone is cold to touch and just idling in a room with AC and the "Optimizing Search and Siri" is already finished, everything is fine when my phone is in 26.6.2 but after updating to ios 27 it randomly shows that false warning that disappears after 10-30 seconds, this looks like a regression to me, im surprised that this bug haven't patched and made it into release, it's present since ios 27 db2

Exactly same thing happening with my phone . I started facing this issue right after the ios 27 updates. Is there any soulution?

No Sir in an air conditioned room even on idle my phone showing this error and when ever it occurs it goes away in 5 to 20 seconds it start happening right after the ios 27 update

Anything you found about this issue? It’s been days now the error is still there

Apple doesn’t care about anything except MONEY !!!
