“In a new JerryRigEverything video, the snazzy rear vent on ASUS ROG Phone 2 has been found to be practically non-performing”
The ASUS ROG Phone 2 is a rather well-equipped phone in terms of specifications, and also comes with the added benefit of snazzy, unconventional styling. While elements such as mid-device USB ports and RGB LED lighting on the back make for rather attractive device, the rear heat dissipation vent used on the ASUS ROG Phone 2 is apparently just a cosmetic piece, without any “real” utility as such. The revelation has been brought forth by none other than teardown veteran JerryRigEverything, who dissected the ASUS ROG Phone 2 in a recent video.
As seen in the ASUS ROG Phone 2 teardown, the asymmetric “ventilation plate” is a separate entity from the rest of the phone’s rear panel. However, it did take quite a bit of effort in taking off, being attached with screws and adhesive to the base plate inside. Once it is detached, it is found to be a metal plate with a plastic inner insulation that offers no real heat dissipation technique. On top of that, it also features a metal grille to the bottom, which is directly exposed to the main board. This is a major design flaw and can essentially wreck your ASUS ROG Phone 2 unit if it accidentally gets exposed to water.
In a bid to make the ROG Phone 2 look good, ASUS appears to have hit the potential durability of the device with a double whammy, where neither is it aiding the performance, and on top of that, compromising durability as well. This seems more like a design oversight from ASUS, since while many companies do not particularly advertise water resistance any longer, most premium smartphones today come with some degree of insulation to accidental water exposure.
However, not all seems to be bad. JerryRigEverything’s video does note the flexible use and placement of the LED strips and reflectors, along with a nifty, silent pull tab that allows the massive, 6,000mAh battery to be taken out very easily. However, the overall arrangement of elements on the main board appear to be a bit haphazard and untidy — something that generally does not make for good board assembly design. While access to the main heat dissipation plate means the display will break for sure while being taken off, the massive copper plate inside is actually quite impressive.
The seemingly huge heat dissipation plate appears to be super tolerant to heat, going by its surface area. This further raises the question of why ASUS required the external faux grille to be put, seeing that their internal thermal management system (there is also some thermal paste between the SoC mount and the copper heatsink) looks able enough. As a result, if you own the ASUS ROG Phone 2, or are planning to own one, be warned against accidental exposure to any form of liquid, for even one slip of the hand can be potential disaster.
