Some reviewers criticize the HUAWEI Mate 70 Pro for not the most advanced technology in the processor. Today we are testing how important nanometers are in the chipset and how long the HUAWEI Mate 70 Pro can work on a single charge in different conditions.
Advanced technological processes make it possible to achieve high energy efficiency of mobile hardware. This is the simplest and most straightforward way to make the gadget work longer. But not the only one. Full control over hardware and software, as well as careful optimization of the OS, have a similar effect: a balance is achieved between sufficient performance and minimal power consumption. Let’s see how HUAWEI engineers coped with this.
Unexplained secrecy
The autonomy of the device depends on many factors. But there are three main ones: economical hardware, a capacious battery, and optimization of power consumption by the operating system. Everything should function perfectly and complement each other. Therefore, let’s briefly run through the filling of the HUAWEI Mate 70 Pro.
The basis of the gadget’s architecture is the Kirin 9020 chipset. There is no official information about it – HUAWEI does not say anything. So, I had to use software methods and some leaks to find out at least something about this processor.
With the help of AIDA64, it was possible to find out that Kirin 9020 consists of three clusters, and the total number of cores is 12 pieces. Moreover, all of them, unlike their predecessor in the face of the Kirin 9010, switched to their own HiSilicon architecture. The fast cluster consists of 2 cores (0x0D05) with a maximum clock speed of 2.5 GHz.
The medium contains 6 cores (0x0D46) that boost to almost 2.2 GHz. And the energy-efficient one boasts only 4 cores (0x0D23) with a frequency of 1.6 GHz. It is better not to ask about the technical process – there is no exact information. Presumably, it is 5 or 7 nanometers from the Chinese chipmaker SMIC. But this is not so important, since all these numbers have long slipped into marketing.
But everything about the battery is known for certain. Its capacity is 5500 mAh, and this is quite a good figure for a device with a 6.9-inch diagonal. Silicon-carbon battery – finally, the new technology is going to the masses.
Such batteries have several advantages over classic lithium-ion batteries – higher rated capacity and charging speed, stability of operation at low ambient temperatures. But the most important thing is the smaller size and heating. The last two points are especially relevant for mobile devices.
HUAWEI Mate 70 Pro Telling figures
The HUAWEI Mate 70 Pro has long turned from a means of communication into an entertainment media center. People watch movies, surf the Internet and play games on it. Therefore, let’s choose the most popular scenarios for testing autonomy: watching and shooting videos, as well as getting stuck on social networks and various sites. PCMark Work 3.0 battery life will also come in handy for measurements — unbiased benchmark indicators are also important. We set the brightness to the maximum to create the most difficult conditions for the gadget. To estimate consumption, we will convert the mAh specified in the settings into a percentage of the battery capacity.
First, let’s talk about the performance in the PCMark Work 3.0 battery life test. In it, the HUAWEI Mate 70 Pro gave a decent result – 12 hours and 35 minutes. And this is taking into account the fact that Kirin chips are produced by Huawei using not the thinnest process. Now to the real tasks. Let’s start by watching the video. Let’s check how much the HUAWEI Mate 70 Pro battery will drain when watching a clip in Full HD resolution from VK when connected to a mobile network and Wi-Fi.
To save energy, it is better to choose a Wi-Fi connection – to watch an hour-long video, you will need to use only 5% of the charge. Switching to a mobile network will raise your appetite by up to 6% — a small price to pay for the ability to watch TV shows wherever you want.
Video shooting is a very energy-consuming process: the matrix forms a large data stream, the signal processor processes and encodes it on the fly into the codec required by the user, and the storage controller writes the resulting content to memory cells. In general, everyone is busy. So, choose a 4K resolution with 60 fps and put a geotag so that the GPS does not stand idle either. One hour of shooting will require 23% of the battery’s energy.
It should be borne in mind that the HUAWEI Mate 70 Pro gets quite hot during video recording. But it is worth giving the brand’s engineers their due: the device tried to reduce the temperature by slightly reducing the brightness of the screen but did not slow down – the recording is smooth, without missed frames.
In the last test, we used a Wi-Fi network and a Yandex browser. In such conditions, for an hour-long look at the cats, it was necessary to use up 15% of the battery charge. Considerably. No wonder they say that doomscrolling has a negative effect on people. As it turned out, not only on them.
HUAWEI Mate 70 Pro Fast, but there is a nuance
As befits a flagship, the HUAWEI Mate 70 Pro supports fast charging. Not just fast, but very fast – 100 watts for such a small device are claimed. Even some laptops come with less powerful chargers. The user has a choice between charging modes: “Slow”, “Fast” and “Turbo”. For the latter, the speed of energy replenishment is surprising: in 19 minutes, the battery is charged to 50%, and fully in 51 minutes. However, there is a nuance – for another 20 minutes, the device continues to consume about 5 watts from the outlet. Here is a small life hack from HUAWEI.
But to get such amazing figures, you need a suitable charger. The HUAWEI Mate 70 Pro supports the following standards:
- 20V/5A (100W)
- 20 V / 4.4 A (88 W)
- 10 V / 4 A (40 W)
- 10 V / 2.25 A (22.5 W)
- 4.5 V / 5 A (22.5 W)
- 5V/4.5A (22.5W)
- 9 V / 2 A (18 W)
From any others, you will replenish the battery at 10-watt power for about 2.5 hours.
HUAWEI Mate 70 Pro Results
According to the test results, the HUAWEI Mate 70 Pro proved to be a fairly autonomous smartphone. It should be admitted that it is not without flaws, but gatherings on the Internet and video filming are the most resource-intensive operations. But if you average the scenarios of operation and do not lean on gaming, the charge will last until late in the evening. As in any flagship today. And if you need to stick to your phone any longer, just plug it into a power outlet for 15-20 minutes to get a few more hours of hard work.
