1 1 series mobile phones are accused of serious fever. Is it Xiaomi or Snapdragon 888 pot?

Recently, a large number of netizens left messages under Lei Jun's personal Weibo, saying that Xiaomi 1 1 had problems such as excessive fever, WiFi failure and motherboard failure. I hope Mr. Lei will give me a response.

According to Caijing Technology, in a Xiaomi user rights protection group, more than 1800 people are seeking solutions with brands through purchasing platforms. At present, there are not only Xiaomi 65,438+0,654,38+0, but also Xiaomi 65,438+0 Pro and Xiaomi 65,438+0,654,38+equipped with Snapdragon 888.

Xiao Chao, a mobile phone enthusiast, told Caijing Technology that at present, no matter Xiaomi 1 1 series or other models equipped with Snapdragon 888, there are generally different degrees of fever, but Xiaomi 1 1 fever is mentioned more. However, it is controversial whether Xiaomi or Snapdragon 888 caused the fever.

Consumers who participate in rights protection said that it is understandable that there will be unqualified products in a certain batch of products, but there will be a large area of unqualified products, indicating that the manufacturer's product design is flawed. How to solve the problem of product design is what manufacturers should think most.

Xiaomi 1 1WiFi failed, and the problem reappeared after replacement.

Lei Ling was so emotional because the Xiaomi mobile phone he bought 1 1 had a hardware problem that WiFi could not be used twice. In the process of seeking a solution, he said that he met Xiaomi's home and the after-sales party kicking each other's balls, and the mobile phone thing has never been solved.

Science and Technology Lei Ling told Finance Technology that his Xiaomi 1 1 was1bought from the offline store of Xiaomi's official direct selling Xiaomi Home on October 8th. After normal use on May 5th, WLAN and hotspot could not be turned on. I went to the official after-sales inspection on May 6th. It was a hardware quality problem, and I got a new one.

"Without any warning, but suddenly stuck, black screen restart. After starting, WiFI and hotspots can't be turned on, "said Lei Ling, a technology company. On the afternoon of August 4th, Xiaomi 1 1 was also in normal use, and WLAN and hotspots could not be opened after the black screen was automatically restarted. This time, he can't stand it. "The last time I accepted the replacement was because I heard that there was something wrong with the first batch of designs, so the replacement machine was definitely no problem. Who knows that there is still a problem with changing the machine, I have been changing it for several months, so I ask for a return this time. "

However, Xiaomi did not return the goods for Technology Lei Ling. Science and Technology Lei Ling pointed out that Xiaomi Home, the seller, said it could not return the goods without an after-sales return form. After sale, it is said that only a list of hardware problems can be opened, and a return order cannot be opened. Science and Technology Lei Ling said that she contacted Xiaomi 400 customer service, and Xiaomi 400 customer service said that products over 7 days could not be returned for refund.

In this regard, Lei Ling pointed out that this problem should belong to the design of individual products. At present, it seems that only Xiaomi 1 1 and Xiaomi1/ultra have it, and Xiaomi 1 1 has many problems. He said that there are many netizens like him on the Internet, and even they have endured three computer changes and still have problems. He can't understand why Xiaomi 1 1 has such a big problem, but there has never been an official explanation and a solution.

It is worth noting that in the after-sales service list exposed by Science and Technology Lei Ling, it is only said that WiFi can't be turned on/off, and the detection fault is true, but the cause of the fault is not given.

Xiaomi 1 1pro black screen crashes.

Also troubled by mobile phone failures are consumers such as Ms. Deng.

There are 1805 people in Ms Deng's group. They all deal with brands or platforms according to their own situation, trying to solve the problems encountered by their Xiaomi mobile phones.

Ms. Deng's Xiaomi after-sales disassembly inspection list has no fault reason, which makes her unacceptable. She said that electronic products will definitely have such a small problem. "But it's hard to have the same problem as this. I think the main problem of Xiaomi is that the test results and the reasons for the problems of Xiaomi 1 1 series are not given. Companies that produce electronic products can't detect faults, so can I suspect that the product design is defective? "

According to Ms. Deng, the previous list would have the cause of the failure, but now it is to describe the failure. When you meet a better engineer, you will verbally say what caused it.

Ms. Deng told Caijing that she snapped up Xiaomi 1 1pro on June 2, and June 10. She asked the customer service if the mobile phone was hot. She said that in the past two months, it has been used well, except that it is hot, especially when the camera is concentrated on the top of the back of the fuselage; Will flash back, suddenly restart the phone, and the boot time is very long, this problem has also been consulted with customer service.

In the picture presented by Ms. Deng, the temperature of the mobile phone is 47, and she asked the customer service how to cool the mobile phone.

Ms. Deng said that the phone suddenly went black at around 8.2 pm 1 1, and she also asked customer service to solve it. In the next few days, she has been buying a platform to handle Xiaomi's customer service. There are three main demands: first, please let Xiaomi know clearly whether it is possible to issue a test report to explain whether it is artificial and judge the cause of the failure; Second, 1 1 series products have the same problem. Why does Xiaomi have a policy of 1 1, while other products don't? Third, exchange it for a new one or get a refund.

"Commissioner Xiaomi made more than a dozen phone calls and did not respond to any demands, including the most basic one." Ms. Deng said.

At noon on August 4, Ms. Deng went to Xiaomi authorized store for testing. Ms. Deng said that before the disassembly test, she repeatedly confirmed to the store manager and the engineer whether a non-artificial or artificial test report could be issued to judge the cause of the failure. The store manager said they didn't issue test reports, only after-sales service records. Ms. Deng further asked whether the above items would be written on this list and told that they could, so she agreed to disassemble the machine for testing.

"After the test, the engineer verbally told me that it was a screen problem or a motherboard problem, and handed me the after-sales service record for me to sign. I read the record sheet, which only described the fault, without mentioning the cause of the fault and whether it was man-made. " So, she had an argument with the store manager, and the result of the argument was: first, the Xiaomi authorized store in Cheng Nan, Dongguan could not detect what caused it; Second, the record table does not indicate that human refers to non-human; Third, it is impossible to issue a test sheet describing the cause of the failure.

Ms. Deng called Xiaomi 400 to test a single thing, and the customer service clearly told her that when she returned to the factory, she could not issue a test sheet or indicate the cause of the failure. After the mobile phone is repaired, there will be a corresponding report to give the customer the cause of the failure.

Ms. Deng said that Xiaomi sent many commissioners to contact her, but she was either sorry or asked her to take the after-sales engineer's test as the standard, but she didn't even give the cause of the failure after the sale. Ms. Deng doesn't know what to take.

Is it Snapdragon 888 or Xiaomi?

In fact, shortly after Xiaomi 1 1 came out, it was reported that the fever problem was serious. At that time, Jin Fan, director of Xiaomi products and general manager of MIUI experience, released a response to the user's feedback on the fever of Xiaomi mobile phone in Xiaomi community.

In response, there are four official reasons for Xiaomi 1 1 fever: First, in pursuit of extreme performance, Xiaomi flagship machine adopted high-standard hardware and partial performance scheduling, which brought more power consumption; Third-party applications are iteratively updated, the system load continues to increase, and the power consumption of mobile phones also increases; Second, the increase of charging power brings faster charging speed, but it also brings the risk of heating; Third, some requirements of external environment, such as the application of operator 5G SA, make some original power consumption optimization methods invalid, increase the power consumption of data network and increase the risk of heating; Fourth, the gradual warming of the weather is also a factor in the increase in the temperature of mobile phones (of course, this cannot be used as a reason).

Xiaomi said that the software and hardware were disassembled and analyzed internally, and the corresponding optimization strategies were formulated, hoping to further enhance the user experience, including: First, introducing intelligent frame stabilization technology to give priority to ensuring stable frame rate and reducing fever; Second, for some non-game scenes, an "equalization mode" is being designed and developed, which can intelligently switch the resolution and refresh rate according to different applications, and the control of background applications is stricter; Thirdly, in order to optimize the fluency, the previously developed scheduling scheme TurboSched is readjusted, the parameters are optimized, and milliwatts per frame are continuously squeezed; Fourthly, aiming at 5G power consumption, mainly the power consumption brought by SA, we have made a differentiated scenario strategy to adapt to the network CDRX and BWP capabilities, and at the same time, we have made scenario control on the premise of ensuring the priority of SA data experience.

At the same time, Xiaomi also said that most mobile phones on the 888 platform have introduced game frame stabilization technology. The balance mode and performance mode of Xiaomi mobile phone have been in the internal testing stage. Ordinary users default to the balance mode, saving electricity is basically smooth. Enthusiastic users can choose their own performance mode (expected to go online in August); The adjustment of scheduling parameters has been introduced into Xiaomi 1 1, so the function response is good, and other 888 platform phones will be gradually introduced at the end of this month.

In response to the above solution given by Xiaomi, Xiao Chao, a mobile phone enthusiast, told Caijing Technology that the game frame stabilization technology mentioned by Xiaomi is actually frame locking. For example, in a game like Genshin Impact, the highest picture quality is 60 frames, and after ten minutes, it will be locked to 45 frames and stabilized to 35 frames, which will greatly reduce the temperature of the mobile phone. "However, after forcibly locking the frame, the experience of the game will be worse than before, and the heat dissipation is at the expense of performance."

He pointed out that the issue of Xiaomi 1 1 series fever or Snapdragon 888 has always been controversial, and some people even think that it is related to the immature technology of Samsung OEM Snapdragon 888.

Xiaochao told Caijing Technology that at present, both Xiaomi 1 1 series and other models equipped with Snapdragon 888 generally have different degrees of fever, but Xiaomi 1 1 fever has been mentioned more. "Some people think that the peak performance of Snapdragon's 888CPU core is very high, so the peak power consumption is not low, and its own fever is serious. Others think that Xiaomi pursues extreme performance too much and adopts more aggressive frequency scheduling. They think that Xiaomi is not doing well in heat dissipation. "

In the view of Ming, the founder of science and technology, the product fever has a lot to do with the problem of 888 chips, and other brands also have such problems. According to this progress, there is a high probability that a VC will be added to the future 5G mobile phone, which will bring challenges to the shape design of the mobile phone. "The chip and the terminal need to strengthen cooperation, and Qualcomm dragged the terminal back several times."

Song Qinghui, a famous economist, said that from a technical point of view, this may still be due to the immature technology. Xiaomi has developed rapidly in recent years, but after-sales, technology and service can't keep up with the development speed, resulting in frequent problems.

Can the problem be solved?

Previously, Snapdragon 8 10 also experienced rollover, but Xiaochao told Caijing Technology that Xiaomi 1 1 got the stable performance output with high heat, which was different from the thermal frequency reduction locking of Snapdragon 8 10.

Xiao Suanmiao, a master of engineering at Tongji University, also pointed out that there were many reasons for the 8 10 rollover, such as 64-bit cutting, high power consumption of large core, insufficient engineering technology, and poor heat dissipation of original mobile phones.

At the same time, he pointed out that the fever problem of Snapdragon 888 was a bit serious, but it was different from Snapdragon 8 10. The problem of Snapdragon 888 is that it can't restrain power consumption under high load, which is a great test for the tuning choice and stability guarantee of the manufacturer. It is not unusual to make a completely different experience with the same soc.

He said that he has three mobile phones equipped with Snapdragon 888, and the fever problem of Xiaomi 1 1 is not caused by the high load like that of Shen Yuan, but the occasional fever of some routine applications, which appears in the process of using WeChat, Cool Dog Music and Gaode Map. Once overheated, the power will drop sharply.

"The problem of Snapdragon 888 is more reflected in Xiaomi 1 1, which is determined by many factors." He believes that these elements include Xiaomi's world premiere Snapdragon 888, which is deeply bound to Snapdragon 888 in public opinion; In addition, Xiaomi is the first mobile phone to ship Snapdragon 888 on a large scale, which is the best and only choice for early adopters, and these people just have the right to speak online; Moreover, the initial shipment of Xiaomi 1 1 is large enough, and most of the recipients are active in major network platforms, making it easier to send out the voice.

In his view, for non-game users, the fever problem of Snapdragon 888 can be completely avoided through system optimization. The current system problems of Xiaomi 1 1 are believed to be solved in the future with the polishing and maturity of Snapdragon 888 and the continuous iteration of miui 12.5.

Technology and Ms. Deng also expressed their understanding of the problems of 888 and Xiaomi, but for them, they just hope that the government can properly solve the problems, instead of the other party pushing the ball all the time when consumers seek after-sales.

"I can understand that there will be unqualified products in a certain batch of products. I also believe that no manufacturer aims to produce and sell inferior products. However, when a large-scale unqualified product appears, it shows that the product design of the manufacturer is flawed, and how to improve the product is what the manufacturer should think most. " Ms. Deng said.
