The OnePlus 15 is criticized for severe heating issues. Now the manufacturer responds – but does not acknowledge that users may experience shutdowns and loss of functionality.

OnePlus has come under fire after a series of tests revealed that its latest model, the OnePlus 15, is struggling with serious issues with heat generation under load.

Several reviewers have documented that the phone reaches over 50 degrees on the outside and in some cases shuts down to protect its components.

The model uses the new Snapdragon 8 Gen 5 chipset from Qualcomm, which is now at the center of the debate about whether the thermal design of modern phones is adequate.

Test results raise concerns

Reviews from Android Authority, Wccftech, NotebookCheck and others show that the OnePlus 15 can reach temperatures of up to 52.7 degrees during intensive use.

This happens especially during gaming or benchmark tests, where the surface of the phone becomes so hot that it is uncomfortable to hold.

In several cases, the phone automatically shut down before the tests could be completed.

The system also disabled features like the flashlight and Wi-Fi hotspot to stabilize the temperature when the thermal ceiling is reached.

This goes against OnePlus’ marketing, which emphasizes a new and efficient cooling system that should ensure high performance under prolonged load.

OnePlus: It only happens in extreme tests

OnePlus has responded to the criticism, stating that the problems only occur in tests that do not reflect regular use.

According to the manufacturer, the system is designed to reduce performance when the thermal ceiling is reached to protect the device.

– The stress tests that reviewers perform are far more demanding than typical use or even most popular mobile games, according to a statement to Android Headlines.

OnePlus emphasizes that in everyday use the phone stays within safe temperature limits and that the automatic shutdown is a safety feature and not a bug in the phone.

However, several reviewers believe that it is not enough to dismiss the criticism with reference to the test conditions.

The overheating is mainly attributed to Qualcomm’s Snapdragon 8 Gen 5, which has previously shown tendencies of high heat generation in other phones.

Critics believe that the responsibility also lies with manufacturers like OnePlus, who should ensure that performance is stable and safe no matter the load.

There are also calls for a software update to limit heat build-up and improve the phone’s handling of extreme situations.
