Does Nubia Red Magic 5S have a high efficiency? This is a rhetorical question, considering that it has Snapdragon 865, 12GB of LPDDR5 RAM, UFS 3.1 internal memory, and in addition a unique cooling system. It is called ICE 4.0, based on three elements – a rod with a cooling liquid, a fan and a silver plate visible at the back of the housing. As an option – we can buy a fan with a radiator, which can be placed on the phone, which achieves 8000 rpm.
What can I write to you? This is simply one of the fastest, the most efficient smartphone on the market. Its power is uncompromising. We just need to look at benchmarks. For me, as a casual gamer, the most important thing was for the device not to have a tendency to overheat. When it comes to such an enhanced cooling system, there are no reasons to be afraid that the temperature will exceed values of decency and will decrease the efficiency of the device in any way. However, there is a drawback: the fan is loud and it can bother you while gaming, and it will definitely bother you while watching videos. It is best to turn it off while doing this.
In my opinion, the additional, optional Ice Dock fan is useless. I did not notice that adding it enhanced the work of the phone, however, it really bothers us after putting it on the smartphone. What is more, it cannot draw power from the phone, so you need to plug it to a power source. And if you would like to cool and charge the phone at the same time, you need to use a cable added to Ice Dock, which is short enough that it requires to move the add-on. And then, Ice Dock can press power or volume control buttons. Someone did not think this through. As a consolation – this add-on can be used for other phones, of up to 93mm width.
Nubia Red Magic 5S is equipped with a 4500 mAh battery, which is relatively small for the level of advancement of this construction. It is difficult to assess these lifespans, because they mostly depend on the way we are using the phone. If we use it as a regular smartphone, with the basic refreshment, turn off the backlight and the fan, we will choose the auto brightness control, our Nubia can work without any problems for 2, even 3 days.
However, if we use full capabilities of the phone (and it was created for this), we must be ready that it will work much shorter. Only for a few hours. The difference can be easily seen while comparing that time of playing a looped video. Depending on scenarios described above, it can reach up to five hours.
Lifespans are not that bad, but the impression is ruined by a weak, 18-watt charger from the set. It takes an hour and a half to fully charge the phone with it. By using a stronger charger – we can decrease it by a lot. A charger “borrowed” from a competitive smartphone filled the Nubia’s battery in 40 minutes. So it is best to order an optional, stronger charger – I will remind you that the smartphone supports 55 W charging.
