To tell the truth, although the models are different, the conclusions reached by bloggers are similar. These outdated old machines often have the same fate: they can only listen to songs and watch dramas like MP4, and they can barely play some outdated games, such as music and entertainment.
How long does the smartphone last? I think the standard for judging whether a mobile phone is eliminated should be this: most daily apps are not running smoothly, which has reached the level of affecting normal life. IPhone 6S, Xiaomi 6 and Huawei Mate9 are typical long-lived models.
The question is, as consumers, how to distinguish between "nail house mobile phones" and ordinary mobile phones? There are three key configurations that determine the life of a mobile phone, so you must read them carefully before buying them.
First of all, the performance of CPU single core is the most critical. As we all know, the screen size of a smartphone is about 6 inches, which determines that it can only run one APP at the same time in the foreground-and not every app can perfectly support "multithreading optimization".
So unlike computers, the single-core performance of CPU basically means absolute performance, which means the upper limit of mobile phone performance and directly determines the service life. The biggest reason why we don't recommend Snapdragon 8Gen 1 is that the CPU single core is too weak.
In Geekbench 5, Snapdragon 8Gen 1 test, the running score is only 1235, which is only 9% higher than Snapdragon 888. Let's recall that the single-core CPU of iPhone 6S has increased by 56% compared with the previous generation, which is the fundamental reason why A9 has established its status as a great god.
Second, the running memory capacity. As we all know, the larger the running memory capacity, the more apps can reside in the background at the same time. The more applications that can reside in the background, the less likely it is to trigger an "application reload". The frequency of APP overload is reduced, which will reduce the frequency of caton.
In 20 18, 6GB of storage is considered as "excess performance". However, by 2022, Android phones must store at least 8GB to ensure that the whole process is not stuck, and even some game phones have begun to store 12GB as standard. This is because the system and APP will constantly introduce new functions, occupying more and more storage.
Take a chat software as an example, just hanging in the background, it has occupied 733MB of storage. Not to mention mobile games, because the mobile phone processor has no special "memory", so the higher the rendering quality of the game, the higher the storage required. It is no exaggeration to say that storage capacity and processor performance are equally important, and they are both key configurations that determine the life of mobile phones.
Third, the endurance level of mobile phones. Nowadays, smart phones are generally designed with non-removable batteries, so ordinary users can't replace the batteries themselves. If the battery is broken, it means it's time to change the phone.
Lithium batteries are charged and discharged through chemical reactions, and since they are chemical reactions, there will be losses. And as the battery power drops, the voltage of the lithium battery will also drop. So when the battery health drops below 80%, in order to ensure the normal use of the mobile phone, the system will reduce the frequency of the processor to reduce the current-this is the cause of Apple's "frequency reduction gate".
The life loss rate of lithium battery is directly related to the number of charge and discharge cycles. According to the quality standard of iPhone, after the lithium battery is charged and discharged more than 800 times, the battery health may drop below 80%, which means it can last for about two years. A small-screen mobile phone like iPhone SE2 needs to be recharged twice a day, and it may need to be replaced in a year or so.
In a word, the above three key configurations determine how long a mobile phone can last. Do you have any other ideas about this problem? Welcome everyone to discuss together.
