Xiaomi Mi Mix 3 5G is the first Xiaomi smartphone to sport the 5G connectivity. Enthusiasts favoured the Xiaomi Mi 9 to take the glorious baton, but Xiaomi went for the Mi Mix 3 5G instead. As the name implies, the smartphone is the 5G version of the Xiaomi Mi Mix 3. It strikes a lot of semblance to what Samsung did with Galaxy S10 and Galaxy S10 5G. Relative to the Mi Mix 3, this 5G version has three major upgrades in the chipset, network and battery.

Battery and Camera

Xiaomi Mi Mix 3 5G offers more battery juice compared to its Mi Mix 3 sibling. That’s expected because 5G is understood to take more toll on the battery than 4G connection. Also, the 3,800mAh battery can charge rapidly due to Quick Charge 4+ in action.
