LG is getting in on the 5G hype with the new V50 ThinQ — an updated version of the V40 from last fall that keeps the same basic design, but adds support for the next-generation network.

You’ll know that the V50 supports 5G right from the start, thanks to the literally glowing 5G logo on the back of the phone. From a spec perspective, the V50 is only different from the V40 in a few ways: 5G capabilities (obviously), a larger 4,000 mAh battery (since 5G takes more power), and a Snapdragon 855 processor (presumably to support Qualcomm’s X50 5G modem). LG is is also adding a new cooling system to help cope with the extra heat from the new processor and battery.
