Which generation of iPhone has the best quality and rarely malfunctions?

According to research by foreign research institutions, among Apple’s previous products, the iPhone 6 has the highest failure rate, followed by the iPhone 6s, with 22 and 16 respectively. This is a very scary number, meaning that more than one in five iPhone 6s have malfunctioned. However, this situation is understandable, because iPhone 6 is the first iPhone to use a 4.7-inch screen. Many designs and processes were brand new at the time, so it is natural that it is prone to problems. Therefore, iPhone 6 Plus and iPhone 6s Plus are also more prone to failure.

Moreover, in the iPhone 6s generation, Apple used a new type of metal material to make its body stronger, but the coating of this metal has certain It is easily oxidized in the environment, causing the back cover to look corroded and the surface to become pitted. Although Apple does not think this is a quality problem, it has also led many users to have low evaluations of the quality of the iPhone 6s series.

Judging from the survey results, the iPhone 8 Plus has the lowest failure rate, only 3. This is reasonable, because as of the iPhone 8 generation, Apple has not changed the appearance of its products for four consecutive years. The design and technology of the products have basically matured, and the quality of the supply chain is stable. Even the workers in foundries such as Foxconn They have also become skilled workers, and the failure rate is naturally lower.

Although the iPhone 8 series no longer uses a metal body and uses a glass back cover, Apple has already used glass back covers on iPhone 4, 5 and other models, so it is very experienced in this area , therefore the quality of the glass body of the iPhone 8 series is still very reliable. As long as it does not encounter drops or bumps, there will basically be no major problems.

In addition, Apple has added a waterproof design since the iPhone 7 generation, canceled the easily damaged mechanical Home button, replaced it with a non-depressible Home button, and also canceled the It has a 3.5mm headphone jack, thus achieving a high standard of IP67 waterproofing. In terms of daily use, water intrusion is often the main cause of damage to mobile phones. After the iPhone becomes waterproof, the failure rate will naturally be greatly reduced. With the iPhone 11 generation, the waterproof level has been upgraded to IP68. However, the two generations of iPhone XS and iPhone 11 were released too close together, so it is difficult to judge whether the quality is good or not.

The reason why the failure rate of the iPhone 7 series is higher than that of the iPhone 8 series is mainly because the iPhone 7 encountered a "baseband gate". Due to Apple's tangents in baseband design, some batches of iPhone 7 and iPhone 7 Plus will lose network signals after upgrading the system. This cannot be solved through system repair and must be returned to the factory for repair. This problem has caused a significant increase in the failure rate of the iPhone 7 series. In fact, if there is no baseband door, from the perspective of service life, the iPhone 7 series with waterproof and metal bodies will be more durable.

It is worth mentioning that the failure rate of iPhone X is the same as that of iPhone 8 Plus, which is only 3. This is somewhat surprising because iPhone A new product with a new appearance. The reason why iPhone X’s quality is good is presumably due to its price. The starting price of iPhone

In general, smartphones are electronic products, so there is always the possibility of failure. The key is whether the failure can be repaired and the maintenance cost that the user needs to bear. In fact, the after-sales service of Apple mobile phones is one of the best in the world, so you basically don’t have to worry about quality problems when buying Apple mobile phones, because as long as the quality problems are not caused by human factors, they can be repaired or even replaced through Apple after-sales service. For example, the iPhone 7 baseband failure mentioned above can basically be repaired for free.

Of course, the out-of-warranty repair costs for Apple mobile phones are also very expensive. It costs 2,599 yuan to replace a screen of iPhone 11 Pro Max and 4,659 yuan to replace a back cover. If you accidentally break both the screen and the back cover, , the maintenance cost is not much different from that of a new machine. Therefore, Apple users who usually do not like to wear film or mobile phone cases are best to purchase the official AppleCare service. With it, even human-caused faults can be repaired at a lower price. In addition, Apple’s mobile phone repair industry chain is also the most complete. If you feel that official after-sales repair costs are too expensive, you can also choose a third-party repair shop. Although unofficial parts may not be as good, the price is much cheaper. Which generation of iPhone has the best quality and rarely malfunctions?

The core of the question is which generation of iPhone has the best quality and rarely malfunctions? I think this issue should be approached from two aspects. One is based on the specific data given by the market, and the other is objectively judged based on personal real experience data. Although the quality control of Apple mobile phones is indeed good, because they are also produced by Foxconn, Apple has professional production lines, and the production OEM requirements are indeed more stringent than other manufacturers. However, some problems with mobile phones do pass quality inspection or What cannot be detected by testing will only appear during our actual use. Let’s talk about it in detail: 01: Analyze based on real data:

The following is a mobile device repair and security status report released by the data security company Blancco in 2018. The report pointed out that the iPhone 6 has the highest failure rate among all Apple products in the past, with a failure rate as high as 22%. Of course, this phone is also the product with the highest failure rate in Apple’s history.

Because in 2016, a data report also released by Blancco showed that the failure rate of iPhone 6 was indeed still the number one at that time, reaching 13%.

In fact, these two reports cover almost all Apple models since entering the domestic market. Of course, they do not include the XR and XS series models released in 2018; and the iPhone 11 released in 2019. Series models; iPhone12 series models released in 2020.

Why is the failure rate of iPhone6 ??so high? In fact, I think this is caused by many aspects:

For example, iPhone6 ??is indeed the first time Apple has adopted a 4.7-inch screen model, and it will inevitably cause some shortcomings in terms of workmanship, including some optimizations. questions and so on.

On the other hand, the iPhone’s performance is indeed lacking. Because this is Apple's last model with 1G of running memory, if there are too many programs running in the background, it will indeed lack stability. Of course, this includes the backwardness of the processor technology, because it is equipped with an A8 processor. The process is indeed still at 20nm. It can be said that there will indeed be heating when running multiple programs, which is inevitable. This problem has only improved in the iPhone6S era. On the one hand, the processor A9 series has been upgraded to dual-core, and on the other hand, the running memory has been upgraded to 2G memory. Therefore, we will find that although the release time of these two models is only different, It takes a year, but the speed and smoothness of operation are indeed very different.

Of course, there are also some hardware deficiencies. For example, in order not to affect our feel and the thickness of the phone, the iPhone 6 is indeed very thin and light, and it uses 6000 series aluminum alloy, but this material The problem lies in poor corrosion resistance. At the same time, the 6000 series aluminum alloy used by Apple this time is not strong enough, which also leads to the emergence of curved doors. In addition, after we hold it for a long time, the body is prone to oxidation due to sweaty hands and other factors. 02. From an objective point of view, the overall experience of the iPhone6splus series I personally use is good.

Although the failure rate of the iPhone 6s series has reached 16%, in the five or so years of personal use, I have not had a single problem. Of course, I did have to replace two of them. sub-battery. But there are really no other problems, but the disadvantage is that it has indeed added stronger 7000 series aluminum alloy to the iPhone 6 to avoid the problem of sitting in bends, but the problem of oxidation still exists, corrosion resistance Poor.

Personally, I don’t have such a problem because I have been using mobile phone cases. At the same time, the reason why I personally think this phone is good is because I have used it personally. The A9 processor is a dual-core processor used by Apple on the mobile phone. At the same time, the running memory has been increased, and with the optimization of the ios system, up to now, I usually The smoothness of use and normal games is not weak, so although there are data on some problems, it does not represent all, and we have also seen that although the failure rate is high, it is only part of it.

Of course, we also know that there is a baseband problem in the iPhone 7, and in the iPhone A double-sided motherboard design is used internally, so the heat generation is relatively large.

In addition, judging from the data, the iPhone 8plus has only a 3% failure rate, which should be regarded as the lowest failure rate among Apple’s products in recent years.

The reason is that there is indeed no change in the design of Apple 8plus, and this design has indeed continued from the iPhone6 ??to the iPhone8 period, which has been a full four years. Moreover, the design of the home button has adopted a non-depressible method since the iPhone, which reduces the chance of damage. At the same time, the body is made of glass, which has higher hardness and does not have the problem of oxidation. Moreover, compared with the iPhone It can be said that there is still a lot of improvement compared to before. Summary:

From the current data analysis, the failure rate of the iPhone8plus series is indeed the lowest. Mature design solutions and compensation in various aspects, including improvements in processor technology, reduce heating problems. The iPhone6 ??series has the highest failure rate, but the iPhone6 ??series has the highest sales volume among Apple’s previous iPhones, with 220 million units. Of course, from an objective point of view, the quality of mobile phones cannot be determined by data alone, but also based on our actual experience. At the same time, I think Apple's after-sales service is really good, because if there are some minor problems with the mobile phone, they can be replaced for free. For example, if you find a baseband problem with your iPhone 7, you can still get it replaced for free.

Answer completed Why do I say iphone 8 Plus? According to market surveys, the iPhone 8 series has the lowest failure rate

According to a 2018 survey, based on the failure rate ranking of iOS devices, this product has the lowest failure rate. iPhone The 8 Plus only has a failure rate of 3. Of course, the data can only be used for reference, but the data is not groundless. It must have been through market research. In terms of failure rate data alone, the iPhone 8 Plus is better than other series. Better.

Why do I say iphone 8 Plus? Based on my own actual life experience

First of all, I can’t say what kind of fruit powder it is, as far as my own use is concerned. I was originally just because the Apple mobile phone was praised by the industry as being so easy to use, so I bought an Apple mobile phone and played with it with the attitude of giving it a try.

I bought an iPhone 8 Plus, and my mother bought an iPhone 6s. After I used the phone with my mother for a period of time, the iPhone 6s There were a lot of pockmarks on my phone. Those pockmarks were densely packed and looked weird. Later, after searching for information, I learned more about the iPhone 6s. Due to the material of the body, it is easy to cause oxidation in a humid environment. Maybe it is because my mother often I have to wash clothes and my phone has been exposed to water.

The iPhone 8 Plus is waterproof, so my phone is still intact and has not been oxidized. I am still using my iPhone 8plus for several years now. I think the overall experience of iPhone 8 Plus is very balanced. It uses the latest A11 processor, so there is no need to worry about performance. The front of iPhone 8 Plus is an upgraded 7-megapixel camera, and the rear is 12-megapixel. , the various effects of taking pictures have also been improved. It feels good and the quality is good. In the past few years of using iPhone 8 Plus, there have been no abnormalities, so this is why I don't change my phone.

Of course, I admit that there is no perfect product. iPhone 8 plus also has many shortcomings. For example, iPhone 8 plus is made of glass and has wireless charging. The weight has increased to 200g. In comparison with other models, it is not difficult to see that the weight of iPhone8 Plus is at the top. Personally, I feel that young ladies should not buy this model.

Secondly, it is precisely because the iPhone8 plus adopts a waterproof design, so I think the surroundings of the fuselage must be sealed, which can play a waterproof role. But there are pros and cons, and heat dissipation is not so good. Of course there are other advantages and disadvantages, so I won’t list them all here. Because the topic this time is just about which mobile phone is better, so as far as the mobile phones I have used, iPhone 8 plus is my favorite and the best in my mind.

Suggestions for purchasing iPhone:

I think each model of the iPhone series has its own shortcomings. Who can guarantee that there will be 100% zero defects? For example, in recent years, Apple has experienced many so-called gate incidents, such as the bending gate of iPhone 6, the oxidation gate of iPhone 6s, antenna gate, battery gate, etc.

To be honest, we cannot prevent these incidents, but I believe that Apple has now improved these defects. Generally, there will be no problem after using it for several years. After all, Apple is an international brand and will recall the phone if something goes wrong.

As the saying goes, a good customer is God! It’s the uncle! Just imagine who would be willing to abandon such a huge market in our country and not serve our God-like customers well? Unless you get kicked in the head by a donkey. Therefore, I suggest that when buying a phone, you should make a bold choice based on your own preferences and budget! Summary:

I may have a high opinion, the iPhone 8 Plus must have quality problems, but the iPhone 8 Plus I bought did not encounter such quality problems. Which model in the best iPhone series do you think has the best quality? Tell me who is the number one Apple series in your mind?

The 6s generation is good, but a bit old. The 4 and 4s are said to have antenna doors and high and low temperature WiFi doors. The 5 is said to have paint peeling off, the 5s is said to have broken U2 (I have one, and there is nothing wrong with it except two batteries have been replaced), and the 6 and 6p are prone to bending. The 6s has a battery door and a paint peeling door (thank you for the comment downstairs so I can add it), but I don’t know about the 6sp (the battery is really not that good). A common problem with 7 and 7p is that they have no baseband or hands-free. 8, 8p and iPhone Some people say that XR likes to spin circles and restart, but after XS, including XR, the signal is not good [face covering]. No one is perfect, and machines are not perfect, just use them up [I want to be quiet][I want to be quiet]

This is not an unpatriotic comment. I have used Apple 4 and Apple. 4s, iPhone 5, iPhone 5s, iPhone 6s and now Apple With X, the quality of the Apple models I have used is very good. I have never encountered any faults. The 4s and 6s at home are still in good condition.

As a post-95s generation, I used the most basic smartphone in high school (I forget what kind it was). When I was a freshman, I had enough money and directly switched to an Apple 4. It was my first contact with it. The deepest impression of Apple is that it is smooth, so smooth, and the crisp sound when locking the screen sounds very pleasant. However, the night before I went home for the winter vacation, I fell asleep in an Internet cafe all night, and my phone was stolen on the table. I was totally confused when I got home by car the next day. When I got back from school, I took out my living expenses and bought a 4s for 2600 yuan. I still have this 4s at home (more than six years ago). The battery is in very good condition. It has become an antique. There is nothing wrong with it except the operation card, and there has been no malfunction.

I have no impression of 5 and 5s anymore. The one that impressed me the most was 6s. I probably bought 6s in installments when I was a junior in college. 6s and 6 can also be regarded as epoch-making generation products in Apple. After all, it can support a large mobile game like Honor of Kings very smoothly. Its appearance and functions are more modern than those of 4 and 5. My 6s is still in good condition (four or five years ago) and the battery has not been replaced. , now I have basically run out of battery after playing two games of King of Kings. It can be said that my 6s battery can basically beat the 1000-2000 Android phones on the market. After all, I don’t update the system very much, so the smoothness is still there. Leverage.

Finally, let’s talk about Apple It is the top in the field, but it should be noted that there are two common problems with the Apple The screen can be replaced and repaired for free. This is considered a major accident. Fortunately, x has been discontinued very early. ), but most x are fine, and x without these two problems is also very good.

Generally speaking, Apple phones are expensive for a reason. They are top-notch in terms of fluency and appearance. This is also the reason why many people don’t want to use Android after getting used to Apple. Isn’t it true? Money is arbitrary, it is indeed easy to use, and sometimes it can improve efficiency. As for hardware failures, I have never encountered them during use.

I have been engaged in Apple mobile phone repair for about 6 years. Let me try to be as objective as possible! This answer only discusses iPhone6/6plus and above models. The previous ones were definitely better in terms of quality, but now except for the 5s, which can use 4g, none of them can use 4g signals. There is no point in discussing quality.

Above picture

There are only about 15 mobile phones in total.

Here we discuss the ideal state and the real state in two states.

The ideal state is that there is very little human interference during use that reduces the life of the mobile phone! In this state, I think the 6plus model has the best quality. The battery life and service life are very long-lasting. Basically, the battery life will be lower than 80% after 4 years of normal use. The batteries of other models 6s and 6sp are the worst. Apple has also implemented a free battery replacement policy for the 6s and 8th generation. In the future, most mobile phone batteries with glass back cases will need to be replaced in about two years. The glass back shell is not strong enough to dissipate heat and the phone will heat up badly, and the battery will wear out quickly! The same is true for the 7th generation series. When Apple released the 7th generation, it said that the service life of the mobile phone was 24 months, because the previous 6th generation and 6s series were so durable. The only thing that can be compared with it is the iPhone 6, but the 6th generation motherboard has more layer problems than the 6p, so ideally I think the 6th generation has the best quality! However, this is impossible in reality!

In reality, there will be slight bumps and slight water exposure during normal use! The 6th generation and 6p were excluded first because their shells were not hard enough and would easily deform when bumped or placed in a jeans pocket. Deformation could easily cause motherboard problems. The most common problems repaired by peers at the time were touch, NFC problems and rear camera jitter. caused by deformation. The baseband of the 7th generation was out of service due to a lot of minor bumps. Apple extended the warranty to 3 years to address this problem. The 7p was prone to silent phone calls and the rear camera not taking pictures, both of which were caused by minor bumps! The 8th generation and 8p are the generation models with the most problems and the poorest quality. There are many motherboard problems that cannot be repaired during normal use. The biggest drawback is that Apple does not provide free repairs for the 8p only. The Apple

The oxidation problem of the back shell of 6s and 6sp, the problem of poor battery life, the camera all understands the problem, and the problem of wireless chip being damaged for no reason and causing high temperature alarm is also eliminated! 11pro and 11promax adopt a smaller and denser double-layer motherboard chip stacking structure, which results in extremely poor drop resistance and heat dissipation. Rule it out!

Now only the XR and Apple 11 are left. Both of them have LCD screens, very strong back shells, and large battery capacity and long battery life! The model that currently has the fewest problems during repairs, but both of them have sold a lot of sales! More than other models on the market together! Since 11 also uses a double-layer motherboard and xr uses a single-layer motherboard, I think xr is the best quality among current Apple models!

The ones who have the most say should be those who do repairs. I started repairing iPhones from the first generation, and now I have repaired iPhone 11. The models with relatively few problems, I think they are still the models from Qiao Gangzhu’s time, but they are all It has become obsolete, and even if you want to use it, you can’t keep up with the speed. So the problems of the models still in use on the market, iPhone6 ??and iPhone6 ??plus, are that the metal shell of the back shell is easy to deform, and secondly, the touch chip on the motherboard is easy to disconnect and desolder, resulting in The touch is not working well. After Apple improved it, they released 6sp and 6s. The problem of deformation of the back shell was solved. The 6s battery is not durable, and the 6sp camera is out of focus. These problems are common. There are no other major problems. It is considered a classic model. Then come to 7 and 7p. 7 has motherboard baseband door problem and battery problem. It should be the model with the most problems. 7p also has camera out of focus problem. Others are fine. 8 and 8p are prone to motherboard problems, resulting in white Apple and iPhonex screens. Bad, the screen price is high, but everything else is fine. After max and 11, there are fewer problems. The most common problems are broken screen and broken rear glass, but there are almost no other problems.

Thank you for your question. In my opinion, the iPhone 6 series is still good.

A very successful model. Some media once counted the top ten Apple products in the past 10 years, and the original iPad, MacBook Pro, iPhone 6 and 6 Plus ranked among the top three. The cumulative sales of the iPhone 6 series exceed 250 million units, and its impact on the smartphone industry is profound.

The impact of iPhone 6 series. The appearance design of the iPhone 6 series has undergone a major change, which has affected the overall design of the next four years. It is basically a large bezel and a home button. It has been released for 5 years, but there are still many users using it. It uses a 4.7-inch screen, equipped with an A8 processor, a front-facing 1.2-megapixel camera, a rear-facing 8-megapixel camera, and only a 1810mAh battery. Although these hardware indicators are now outdated, they do not affect the overall performance and daily use of the phone. It shows that the quality of the iPhone 6 series is reassuring.

5s, I bought it when it was first launched, and the local gold price increased! So far I have replaced one screen and one battery, and I don’t know how many times I dropped it. Please refer to the appearance! I used it until the first half of last year, and then retired it for retirement! Planning to collect it! ! !

Which iPhone has the best quality? There are almost no failures?

I have been using it myself until now, and I can really feel that the quality of iPhones is outstanding. The two mobile phones with the best quality in my own experience -

The first iPhone 4S mobile phone, its performance is very outstanding. I have used it for so many years and it can still be used normally. More importantly, , in terms of performance, it still maintains extremely strong performance characteristics.

Our other mobile phone is the iphone 6. I am satisfied with this phone in terms of size and appearance, and it has been used for a long time. From the time I bought it, it has The main feature is its back cover, which is made of stainless steel, which makes the quality characteristics of this phone very obvious.

We also know that the 4.7-inch size of this phone is very suitable for us to hold it. Although the battery is also a problem, in daily use, we can indeed feel that its battery is still stronger than the iPhone 4s. Much more.

I have been using iPhones for such a long time, and I still feel that the quality performance of iPhone 4s and iPhone 6 is still good. At least this is the model with the highest quality of iPhones that I have used so far.
