Execution of complex environmental tests applying extreme environments simultaneously
Improved heat dissipation performance with copper heat pipes

LG Electronics is applying the highest level of safety design and testing to its strategic smartphones to be released this year.

Following the acclaimed 'LG V20' for its outstanding durability, LG Electronics plans to unveil a product focused on safety at the MWC in February, with ▲significantly improved heat dissipation performance, including the adoption of a heat pipe, and ▲'composite environmental testing' that simultaneously applies international standard battery tests and extreme conditions.

LG Electronics significantly improves smartphone heat dissipation performance from the design stage to prevent heat generated during smartphone operation from being transferred to the battery and affecting safety.

LG Electronics is adopting a copper heat pipe, which excels in heat conduction and diffusion. Heat pipes, commonly used in laptops and PCs, effectively disperse internal smartphone heat, reducing the temperature of the application processor (AP), the primary source of heat generation, by approximately 6-10%.

We also strengthen safety testing of the batteries themselves, verifying battery quality with standards that are more stringent than international standards. We also conduct penetration tests, where we pierce the center of the battery with a nail, and impact tests, where we drop a heavy object from a certain height.

The complex environmental test is conducted by simultaneously applying conditions such as temperature, humidity, water and dust resistance, foreign substance ingress, shock, drop, and damage to extreme conditions, and tests various smartphone components such as the AP, display, camera, and fingerprint sensor.
