How to solve the problem that mobile phones are prone to heat and power consumption？ Have a coup

　　Nowadays, smart phones have become more and more popular, and everyone is very concerned about the problem of mobile phone fever when using smart phones. As a kind of electronic products, it is obviously unrealistic to completely suppress the fever of smart phones, but we still have some tips to keep smart phones from overheating in daily use. Let’s take a look at the fever of the mobile phone. How to solve the problem of mobile phone heating and power consumption?

　　First, the cause of mobile phone fever

　　Battery reasons, running too many large programs, high CPU load, damage to internal components, etc.

　　1. When the cell phone number strength is -75dBm, the signal strength becomes very poor. In order to ensure normal cell phone communication, the cell phone will automatically increase the transmission power. The higher the cell phone power, the greater the cell phone fever.

　　2. Multiple background applications run together, which leads to CPU overload, and the thermal effect of the current generated by it can be imagined. Moreover, the theme, background and screensaver are all users of TV University, which leads to the fever of the mobile phone. Especially when navigation, games and videos are running, when these programs are running, gps navigation, Bluetooth, wifi or hotspots will be turned on, which is very easy to cause serious fever.

　　3. When users use mobile phones to surf the Internet and transmit more data, the greater the power consumption, the higher the CPU utilization rate and the higher the calorific value.

　　4. The power consumption of the mobile phone when talking for a long time or using audio and video is very large, that is to say, its battery has a small equivalent load resistance, and it is discharged with a large current when working. After discharging a part of electricity, the internal resistance of the battery increases, but the current required for the work of the mobile phone cannot be reduced, so a considerable part of energy is consumed on the internal resistance of the battery, which leads to the battery heating.

　　5. Because people are used to holding the mobile phone with their hands, the mobile phone cannot dissipate heat. If you use your mobile phone for a long time and the heat dissipation is not good, it will also cause your mobile phone to heat up.

　　6. Charging with a non-original charger leads to the fever of the mobile phone. Such a charger lacks a protection circuit, which cannot guarantee the stability of the current when charging, and it is easy to burn out the battery, shorten the service life of the battery, and even have the danger of explosion.

　　7. When you play with your mobile phone while charging, the battery will heat up when it is charging, such as making phone calls and playing games, which will aggravate the fever. If the weather is hot and the mobile phone is covered, the mobile phone is very easy to get hot, and it is also easy to get hot with a thick mobile phone cover.

　　8. Hardware or battery failure of the mobile phone itself can also cause burning, but generally this kind of situation is less.

　　Second, the consequences of abnormal fever in mobile phones

　　If the abnormal fever of the mobile phone is not handled in time, it is easy to cause the following problems:

　　1) The most direct thing is to damage the battery and reduce its service life.

　　2) Damage to other mobile phone hardware, and the most extreme case is that the mobile phone explodes and hurts people.

　　3) It may cause system disorder, and it is easy to dial the phone by mistake and open the application indiscriminately.

　　Third, the handling method of abnormal fever of mobile phone

　　After abnormal fever occurs, you can use the following methods depending on your environment and specific application:

　　1) Physical cooling if possible. Put it in the air outlet of the air conditioner, or throw it into the refrigerator to cool down urgently. After the temperature drops, it won’t hurt the phone itself, then check what power-consuming programs are opened and turn it off.

　　2) When it is already very hot, turn it off immediately. After shutting down, it is equivalent to killing all the programs, and then turning it on after the temperature drops.

　　3) When the fever trend is relatively large, you can turn off gps positioning, wifi, Bluetooth and even direct flight mode. Or play games for a long time, just have a rest.

　　4) Other conditions, such as unplugging the charging cable, removing the phone case, or getting hot, let the phone rest.

　　Fourth, the reasons for mobile phone batteries

　　The damage of mobile phone battery is an important cause of mobile phone fever. With the mass production of mobile phones, their quality is uneven. Especially the cell phone battery is a problem that puzzles people. If your mobile phone has two batteries, change the other battery to see if it is still hot. If it is no longer hot, it means it is a battery problem. If it is still hot, please see the second method.

　　Solution to fever caused by running programs: Today’s smart phones can run applications that can only be run on computers before, but some inherent defects of mobile phones will bring us trouble, that is, fever. If you open too many applications, the load on the CPU of the mobile phone will be high, and the heat will be great. The solution is to close some large-scale running programs, and other programs that are not used should also be closed. If the phone is still hot after taking this method, please see the third method.

　　Solution of internal component damage: If you use the above two methods, the phone is still very hot, then you should consider the problem of internal component damage. If your mobile phone is still in the warranty period, you can take your mobile phone to the merchant for warranty or replacement; If your mobile phone has passed the warranty period, you need to pay for it.

　　1. When the mobile phone is at normal room temperature, it is normal for it to heat less than 50℃. When the mobile phone is very hot, remove the back cover of the battery and force heat dissipation.

　　2. It is best to use the original charger, and it is best not to play with the mobile phone when charging.

　　3. Develop a good habit of locking the machine; Don’t press the home button when you exit the program. Press home to build the program, which is still running in the background. Develop unused applications and clear them with one click in program management.

　　4. Charging for too long will damage the battery and generate heat. The normal charging time of the mobile phone is 3-5 hours. How to charge the mobile phone > >

　　5. If the mobile phone battery feels a little hot when charging, if it exceeds 50℃, immediately return to the standby state or replace the battery. If charging, immediately unplug the charger. What should I do if my mobile phone battery is not fully charged? > >

　　6, often do the "one-click cleaning" background program for the mobile phone, and usually turn off some unused function switches, such as WIFI, GPS, automatic synchronization, etc., and appropriately reduce the screen brightness, which will greatly reduce the body heating phenomenon.

　　V. Precautions for preventing abnormal fever of mobile phones

　　Mobile phones are used for making phone calls, playing games, chatting, etc. It is impossible not to use them for fear of fever, but we can pay more attention to things at ordinary times, which can improve this situation. It can only be said that it is an improvement. If it is to be thorough, it can only rely on the improvement of the functional performance of mobile phone manufacturers.

　　1) You can prohibit the background automatic update program of the mobile phone or the background upload and download of icloud. Because these may cause unexplained fever.

　　2) Try not to play with your mobile phone while charging.

　　3) If you wear a cover for your mobile phone, choose a material with better heat dissipation. If possible, you don’t need a cover. When you use your mobile phone in daily life, as long as you develop good habits, be careful not to fall and bump.

　　4) If you are playing online games or navigating for a long time, control the time or take cooling measures.

　　Six, mobile phone power consumption situation and solutions.

　　Fast power consumption of mobile phones has always been a worry for mobile phone users. It’s a bolt from the blue when the mobile phone is playing without electricity. So is there any way to solve the problem of fast power consumption of mobile phones? The answer is yes! As long as you prescribe the right medicine for the following points.

　　Case 1: There is virtual power in the mobile phone.

　　There is virtual power in the mobile phone, which means that when you turn it on, it shows full power, but when you turn it off and then connect the charger, you find that the power display is actually only about 80%.

　　The Android system generally judges the battery charge according to the battery voltage, and there are two modes to recognize the voltage.

　　One is software identification, that is, the power displayed on the mobile phone after you boot into the system; The other is hardware identification, that is, when the charger is connected, the power displayed by the mobile phone is not turned on.

　　Usually, the voltage of software identification is higher than that of hardware identification. Therefore, it will appear that when we turn on the battery, it is full. After turning off the battery and connecting the charger, we find that there is actually only 80% or even lower power. Want to fill it up? It will continue to charge for a long time!

　　In fact, we often don’t fully charge our mobile phones, wasting part of the battery capacity, and naturally feel that the power is falling fast!

　　Solution:

　　Check whether there is virtual power in your mobile phone first: it is fully charged when it is turned on, and then turn it off and connect the charger to see if it is fully charged. If there is virtual electricity, then turn it off and fully use it, and see if it will be powered off again!

　　Case 2: Too many background programs increase CPU power consumption.

　　Don’t be careless about this old-fashioned question. What’s not so good about Android is that it will automatically run in the background after the program exits. Moreover, in the case that there is generally no problem with mobile phones, these background programs are often the biggest culprit in power consumption!

　　There are also the screen brightness of the mobile phone itself, the opening of wifi, Gps, Bluetooth, etc., and other settings, etc. These seemingly insignificant little things are actually big power consumers.

　　Solution:

　　1. Clean up the background operation of the mobile phone regularly to solve the problem that unnecessary programs occupy running memory and increase CPU power consumption.

　　2. Turn down the brightness of the mobile phone screen, turn off wifi, Bluetooth, etc. when not in use, and turn off power consumption settings such as button sound and button vibration.

　　3. Think about whether you have installed a program recently, uninstall it first, and see if the power consumption of the mobile phone is back to normal. Many small programs we ignored actually consume amazing power!

　　Situation 3: Battery aging

　　Nowadays, most smart phones use lithium batteries, and the average life of lithium batteries is 2-3 years. After 400-500 times of charging and discharging, it will accelerate the aging speed and become less and less durable.

　　If we use the mobile phone battery incorrectly every day, it will easily lead to battery aging and battery life decline.

　　Solution:

　　Proper use of mobile phone batteries is the best way to prolong battery life.

　　The problem to be solved now is, how do we judge whether the mobile phone battery is aging?

　　1. If the battery has been used for a year or so, according to your usual usage habits, the mobile phone will charge quickly and consume electricity quickly, which is likely to have begun to age.

　　2. Check to see if there is a bulge in the battery. If there is a bulge, it means that it is not just aging, but the battery is no longer usable. For safety reasons, it is better to change the battery as soon as possible.

　　3. After using the mobile phone for a period of time, the battery body has been burning, so you should change the battery as soon as possible.

　　Situation 4: Caused by improper brushing

　　In order to get ROOT privileges or other factors, many people quickly brush up when they get a new machine. But not long after, I found that mobile phones are prone to various problems, especially the power consumption will increase rapidly, which is really disturbing!

　　In this case, generally speaking, the brush is incomplete, resulting in program errors, and then the program will be run repeatedly, and the power consumption will naturally accelerate!

　　Solution:

　　The major brushing systems may have some defects more or less, and some programs on the mobile phone hardware can’t be called, and then these programs will be tried again and again, which is invisible to us. Only after brushing the machine and finding problems when using the mobile phone will we know!

　　At this time, it is best to find someone to help you refresh the machine, refresh the original system or the official ROM system, and then manage the system startup and self-startup software, which can be solved perfectly.

　　Case 5: Short circuit and leakage of the mobile phone motherboard.

　　For those who are familiar with mobile phone hardware, you can manually remove it, and check whether a patch capacitor on the main board of the mobile phone is in poor contact, which leads to a short circuit and causes the mobile phone to heat up, and then check to see if there is any leakage.

　　Of course, this must be tested by professionals, which is more difficult for ordinary people.

　　Solution:

　　Take it to a mobile phone after-sales service point for testing, or go to some regular mobile phone repair shops, and let professionals test it for you. After determining the problem, you can prescribe the right medicine!

　　Seven, mobile phone power consumption is fast, you can also try the following methods.

　　Don’t let the battery run out.

　　The mobile phone battery is fully charged and then consumed, and this cycle avoids the "memory effect". In fact, this practice is only applicable to Ni-Cd or Ni-MH batteries, not to lithium batteries. At present, most smart phones use lithium batteries. The author suggests that in order to prolong battery life and protect battery health, users should fully charge their mobile phones before running out of power.

　　Positioning setting

　　When users use mobile phones, some LBS-based applications often track users’ location, which will also increase power consumption. Although the power consumption increases, users of these applications often use them, and tracking the location can make the applications serve users better. At this time, users can find the corresponding application in Settings-> Privacy-> Location Services, and set the location information that they are allowed to access as "during the use of the application", which can save a lot of electricity when the application is not used. Of course, if you don’t need the location service of this app at all, you can set it to "never".

　　Better use of WiFi network

　　Under normal circumstances, users want to be online around the clock. Mobile phone network is undoubtedly a good choice, but at the same time it also means faster power consumption, especially when the mobile phone signal in the user’s area is not good, the mobile phone will frequently search for operator signals, which will increase power consumption. At this time, if the WiFi network can be used, the mobile phone does not need to search for signals frequently.

　　However, users need to remember that when leaving the WiFi hotspot, users can turn off the WiFi connection. Generally speaking, it is to let the mobile phone stay in a stable network, and it is not necessary to search for signals frequently, so that the mobile phone can save more electricity.

　　Appropriate use of flight mode

　　Similar to the situation mentioned above, there is no busy mobile phone or WiFi signal in the underground high-speed rail, because the mobile phone will keep searching for connections, which will lead to an increase in power consumption. The user can set the mobile phone to flight mode before returning to the place with signal. In addition, turning on flight mode before going to bed is also a good way to save electricity.

　　Low energy consumption mode

　　If you don’t have the rechargeable conditions at hand for the time being, and you want the mobile phone to save as much electricity as possible, users can consider turning on the low energy consumption mode of the mobile phone. Take the iPhone as an example. When the power is only 20% and 10%, the mobile phone will automatically remind the user to turn on the low-energy consumption mode.

　　Low-power mode will temporarily reduce power consumption until your mobile phone is fully charged. When this mode is turned on, you will stop viewing acquisition, background application refresh and automatic download, and weaken or turn off some visual effects. When the iPhone is charged to 80% capacity, the low-power mode will be automatically turned off.

　　Find a big power consumer

　　Now, no matter which mobile phone, you can count the major power consumers in the system for a period of time. As long as you know who consumes a lot of power, users can optimize their use. The mobile phone is running out of power, and you must have overdone one of your applications. IPhone users can get an overview of the most power-consuming applications in the past 24 hours and the past week in the "Battery" option.

　　Android users can also select the "battery" option, and the system will display a chart of power usage since the last charging and a list of applications that use the most power.

Fresh food is destroyed by ＂sinking＂ when it comes home. Why can’t you avoid these pits every day？

Text | understand notes

Delaying service, protecting employees’ rights, breaking the capital chain, and executives’ "running away" ……

From the end of July, the "originator" of the fresh-food home model — — Fresh food every day has always been a negative rumor. A series of "tug-of-war" triggered by its "broken arm to stop bleeding" and the closure of the Speedmaster business have also been staged in many places: gossip, media reports, corporate rumors, and overwhelming news.

On August 9th, according to official website news of Beijing Consumers Association, Daily Youxian was interviewed by Beijing Consumers Association on the afternoon of August 4th because of "unable to operate normally and causing a lot of consumer complaints". Although the official platform gave a notice of service change: "the delivery time is the fastest delivery the next day", the interview also confirmed the rumor that it was "in trouble".

Some analysts pointed out that the three modes in the fresh e-commerce industry — — Pre-warehouse (fresh food comes home), warehouse-store integration, and community group purchase, the pre-warehouse model itself is the most difficult to make a profit, and it is also a heavy cost, which has also become the main reason why the daily fresh food is in trouble; Some analysts believe that there is nothing wrong with the daily excellent "urban sorting center+community pre-warehouse" secondary storage system itself, but discount subsidies and excessive involution in staking, which makes it difficult to return after losses.

Looking at it from another angle, is it a tragic "pit avoidance guide" for other players in the field of fresh food?

Is the so-called pre-warehouse mode of fresh e-commerce a pit?

Take a look at the recent situation of another player in the industry. In addition to fresh food every day, it seems that the previous days were not easy. As early as June, it was reported that under the continuous loss, Ding Dong bought vegetables and withdrew from more than ten cities to survive.

According to the relevant financial report of Ding Dong’s grocery shopping, most of the company’s net loss of 6.429 billion yuan in 2021 came from the front positions in the second and third tier (cities). Therefore, it has to shrink its network channels and close its business in cities such as Tangshan, Langfang, Xuancheng, Chuzhou, Zhongshan, Zhuhai, Qingyuan, Jiangmen, etc., mostly sinking the market in the third and fourth lines.

Although the financial report for the second quarter of 2022 (as of June 30) released by Ding Dong recently saw the dawn, it was only a staged victory: the total revenue of Ding Dong’s grocery shopping in the second quarter reached 6.63 billion yuan, a year-on-year increase of 42.8%; Non-GAAP’s net profit was 20.6 million yuan, achieving phased profit for the first time. The data shows that the net loss of Ding Dong’s grocery shopping in the same period in 2021 was 1.7285 billion yuan.

So, what is the biggest challenge for fresh food to reach the home market in the future?

"I feel that the more the market sinks, the more difficult it is to do the mode of fresh food."

In 2021, in order to take care of the sick family, Huan Jie (pseudonym), who worked hard in Shanghai for more than three years, resigned and returned to his hometown in Wuhu. He applied to be the operation manager of the local "warehouse-store integration" site, which is regarded as continuing to connect with the "Internet" in this manufacturing-oriented city.

During his work in "Magic Capital", Huan Jie was used to buying fresh products through fresh food. However, after working as a store manager in his hometown for more than a year, he found that the mode of fresh food coming home in small cities was almost difficult to improve.

"In order to seize the market, the price of the fresh platform is cheaper than that of the vegetable market, but few people buy it." He told him that he knew how to take notes. Although the store was located in the city center, the daily order volume of users was less than a quarter of that of a store in the suburbs of Shanghai, and he was losing money almost every month.

In his view:The sinking market "doesn’t catch a cold" about the mode of fresh food coming home, which has nothing to do with the price of products and the local consumption level, but is closely related to the consumption habits of residents. More precisely, it is the "aging" problem of sinking market, which hinders the development of fresh food in small cities.

"It’s not the same as when I was a child. Today, there are many middle-aged and elderly people on the streets of Wuhu, and there are very few peers." As for the reason, Huan Jie explained that, like many third-tier cities, "the siphon effect of big cities has caused local young people in Wuhu to flow out." When communicating with his classmates, he found that the problem of "aging" in Wuhu city is actually quite good, and some cities are more obvious.

According to the statistics of CBN, 149 cities in China have entered the stage of "deep aging". Eleven cities, including Nantong, Ziyang, Taizhou and Zigong, have fallen into the stage of "super aging".

Almost all of these cities are small and medium-sized cities, and they are also "sinking markets" among the Internet population. Huan Jie told those who understand notes that compared with young people who pay attention to convenience, it is difficult for middle-aged and elderly people who don’t like to be "arranged" to accept the mode of buying food fresh at home.

Even if middle-aged and elderly people have learned to buy "industrialized" products with uniform quality on the e-commerce platform, they still insist on the pursuit of freshness of meat dishes. As for the young people in small towns who are used to eating "home cooking", naturally they will not worry about buying food and eating like their peers in first-tier cities.

According to the survey data of iResearch:Among fresh e-commerce users, the proportion of people aged 45 and under is as high as 87.7%, among which consumers under 35 account for 57.7%. It can be seen that no matter what segmentation mode of fresh e-commerce, the main consumers are young users..

As for the mode of returning home with heavy stores and heavy pre-warehouses, in the sinking market with serious "aging", it is completely the rhythm of "persuasion".

Obviously, this is also the reason why when the mainstream fresh food platform "breaks the wrist to stop bleeding", it is the reason why the business in small cities is closed first.

"It is difficult for fresh food to gain a foothold in small and medium-sized cities. These big platforms are not unclear."

Talking about the topic of "sinking the market" when fresh food comes home, Chen Yu (pseudonym), who used to be the regional operation manager of a fresh food platform, believes that the chicken feathers left by the fresh e-commerce industry are the result of excessive competition and blind profit-seeking of capital in the industry in recent years.

Under the influence of the epidemic, the fresh e-commerce industry, which was almost "cool" a few years ago, started a new round of expansion in Zhang Zhilu, which was originally "rolled up" in the big platforms of first-tier cities, and all of them sank to the third-and fourth-tier cities after 2020 to tap new incremental users.

"At the end of last year, our platform planned to fully deploy third-tier cities. At that time, after a series of market research with my team, I felt that it was not suitable, so I suggested suspending the plan. But in the end, the top management decided to rush to more than a dozen small and medium-sized cities. " Chen Yu said that at that time, competitors were constantly sinking, and the boss naturally couldn’t sit still.

Regardless of whether there is an "aging" problem in small and medium-sized cities and whether there is sufficient demand for the home-based mode of fresh e-commerce, all kinds of entrepreneurs and platforms are rushing to small and medium-sized cities, scrambling to burn money subsidies, just to cultivate new consumer demand. Behind this, there is the fuel of capital, and there are also operators who are blindly optimistic and eager to race before the formation of new consumption trends.

"At the peak of industry expansion, like the third-tier cities like my hometown Qingyuan, there were four or five fresh e-commerce platforms, of which two were fresh at home, which was to fight with the community group buying platform at low prices." At that time, the fresh "bubble" and false data created by burning money will only make investors more excited.

The Beijing News reported that as of February 2021, there were 17,000 fresh e-commerce related enterprises in China, mainly distributed in Guangdong, Jiangsu, Shandong and other regions. Among them, the number of fresh e-commerce enterprises in Guangdong Province is 4,495, ranking first in the country.

Chen Yu told me that she knew how to take notes. Because the company’s fresh food platform sank in small and medium-sized cities in an all-round way, the sales performance was not bad. At an internal meeting, the company’s senior management accused her of "not doing a solid job in the previous market research", which almost made the company miss the sinking market blue ocean, which made her very speechless.

"In the previous field of fresh e-commerce, no matter whether it was a group purchase in the community or a fresh home, almost all of them were making money at a loss. Everyone wanted to win a bonus hunter. As long as the price was low enough and the subsidies were embarrassing enough, users of any age would flock to the queue to take advantage of it." It can be said that low prices and subsidies are the magic weapon for fresh e-commerce to open the sinking market, but at the same time they are also the shackles for realizing profitability.

In Chen Yu’s eyes, compared with the community group buying mode that only one community leader can open up the market, this fresh-food home-to-home mode, which relies heavily on "warehouse-store integration" or "pre-warehouse", is the least qualified to participate in the low-price war of fresh-food e-commerce industry.

"Although the front warehouses and front stores can join and cooperate, in order to ensure the quality of fresh food to the greatest extent, the platform should fully guarantee that the front warehouses and stores in the core of the city are self-operated, which is a huge investment. There are few self-operated warehouses and franchise warehouses every day, and all the food purchases are self-operated, and everyone’s burden is very heavy. "

Obviously, fresh food with high operating costs has no chance of winning in the battle between sinking market and community group buying.

Then, can we save ourselves in the crisis of survival by giving up the platform of "stopping bleeding with broken arms" in small and medium-sized cities?

Different from Daily Youxian, which is riddled with negative news, Ding Dong, who has bought food in advance, has shown that its income growth rate has not declined in the last two quarters, while its losses have steadily narrowed.

Some analysts told me that knowing how to take notes was the result of "optimizing operational efficiency". From the previous fight for scale, grabbing the market and fighting for subsidies to the optimization of regional layout, the operating cost has just been reduced.

However, in the eyes of some people in the industry, even if these platforms "stop bleeding" and return to rationality (for example, the daily fresh food is changed to the "cloud super sale" mode), and the main energy is focused on the first-tier key cities, it is still not a simple matter to turn losses into profits.

Especially in the current situation that the supply chain system of community group purchase and fresh food to home platform is mature and perfect, it is almost impossible to squeeze out more profits in the supply chain. Therefore, each platform can only increase the premium of fresh products, thus increasing the gross profit margin.

"Our company’s current practice is to emphasize the quality advantage of the home-to-home model in publicity, thus opening the gap in positioning with the low-cost community group buying model and attracting high-net-worth users who have higher pursuit of life to use our home-to-home service."

Moddy is the city manager of a well-known fresh food delivery platform. He told me that he knows how to take notes. In recent years, the trend of "getting worse and worse" of fresh food delivery and "the originator of pre-warehouse" has sounded the alarm for many colleagues.

Because the "natural" operating cost of fresh food is high, we can’t blindly fight for low prices with community group purchases that operate with "light assets". In his view, the big platform should still take advantage of the good quality of fresh products and high delivery timeliness to deeply cultivate the middle and high-end user market in first-and second-tier cities. This view can also be glimpsed in relevant industry reports:

A report released by Guotai Junan shows that in 2019, before the epidemic, the pre-warehouse was fresh at home, and the unit price of users was above 50 yuan; "Warehouse-store integration" mode, the unit price of customers is as high as that of 65 yuan. The unit price of community group buyers is usually between 30 and 50 yuan.

Relevant survey data released by iResearch show that when shopping online for fresh products, users in first-and second-tier cities and users in low-tier cities have quite different factors: users in first-and second-tier cities pay more attention to fresh quality while consumers in low-tier cities pay more attention to product price.

However, it is not easy to re-establish the "high-end" reputation and attract high-net-worth users to consume quality at once. Especially in the past one or two years, the field of fresh e-commerce has fought a low-price war, and some home-to-home platforms are limited by price and cost, which has continuously reduced the quality of products, which has had a negative impact on the fresh-to-home model.

"In the eyes of many mass consumers, community group buying is no different from fresh food, depending on whose price is low. In the eyes of high-net-worth users, the home platform that grabs the market at low prices is not necessarily high-end, and the results are not pleasing. " Moddy admits that there is still a long way to go before the fresh-to-home model can regain the favor of high-end users.

Judging from the only remaining types of players in the industry at present, the daily freshness of fresh food in the front warehouse is declining, and the grocery shopping and the food shopping in the United States (some cities) are steadily and steadily; The representatives of "warehouse-store integration" are Boxma Xiansheng, JD.COM Qixian, Wal-Mart, etc., which are still step by step; Community group buying representatives, if they buy more food and prosper, seem to be eroding the space left by daily fresh food.

The battle of fresh e-commerce is still unclear.

Some analysts believe that the "rout" of daily fresh food lies in the pre-warehouse mode, and some even completely deny the "asset-oriented" operation of fresh food to the home mode. In fact, the most controllable fresh food comes home in terms of product quality and distribution efficiency, and there is still room for exploration in the business model in the future.

The "decline" of fresh food to the home market is largely related to enterprises blindly striving for scale, sinking the market and blind subsidies. A large number of ineffective costs and expenditures eventually drag down the normal operation of the platform. Perhaps returning to rationality and regaining its position is the ultimate way out for fresh food.
