Only days after Telstra were spruiking the all new $1,499 Oppo Reno 5G smartphone a new problem has emerged with the Chinese device heating up when used.

According to Telstra sources the device appears to have a “heat sink” problem when downloading high speed 5G data.

A heat sink is a thermal conductor that carries heat away from a CPU for example in a notebook they have fins that provide a large surface area for the heat to dissipate throughout the rest of the device, thus cooling both the heat sink and processor.

Both a heat sink and a radiator require airflow and, therefore, both have fans built in.

Both Telstra and Oppo are investigating the issue according to the source.

The expensive Oppo Reno 10x Zoom 5G camera that includes a 16MP pop-up camera.

Oppo claims that the pop-up camera has been tested to withstand over 200,000 uses.

The device has 6.6-inch AMOLED display with Corning Gorilla Glass 6, and fingerprint unlocking built into the screen.

The Reno 5G has a x50 5G modem and has a Qualcomm Snapdragon 855 processor. This is the same processor found in LG’s new dual screen 5G smartphone.

The battery delivers 4065mAh, which is equal to about 26 hours of talk time and 340 hours on standby.

At this stage it’s not known whether Oppo will pull the device from sale.

The Chinese Company is not returning calls.
