Why do Android devices become stuck after being used for a long time and Apple devices crash after being used for a long time?

Generally, after using a mobile phone for about two years, you will notice that it is not as smooth as before. This phenomenon used to be more common on Android phones, but in fact, the Apple iPhone, which is famous for its smoothness, will also experience poor experience after a long time of use, and even experience flashbacks, white screens, etc. To understand the reasons, let's start with the root cause.

In addition to the most common problem of excessive system garbage, the slowdown of mobile phone operation is actually caused by the inability of hardware performance to keep up with software requirements. The hardware here mainly refers to the CPU, GPU, memory, and flash memory. The program reads the data in the flash memory, loads it into the memory, and then processes it through the CPU and GPU. These hardware are closely linked.

APP is getting more and more bloated

The most likely cause of lag is memory, because nowadays APP functions and sizes are getting bigger and bigger, causing your memory to be filled up. Android users may find that in the past 4GB memory era, 50% of the memory was occupied when the phone was turned on. Now 6GB and 8GB have become the mainstream, but the memory still takes up 50% when the phone is turned on. It's embarrassing...

The reason why Apple can maintain good fluency without a lot of memory is that Apple uses a "tombstone" background mechanism. When the program is not in use, it will only stay for a short time and then be suspended, thus releasing a large amount of occupied memory space. Android's true background mechanism will take up more memory.

The domestic Android APP ecosystem is extremely chaotic. Many developers "add ingredients" to APP for profit, regardless of user privacy or slowing down the machine. Even some APPs produced by large companies have added various irrelevant functional modules to grab market share, accelerating garbage generation and resource occupation. In foreign countries, Google Play is much better, with a large number of "small and beautiful" applications to choose from. Apple IOS has always had a relatively strict review, and developers are relatively unlikely to do anything blatant.

Flash performance cannot be ignored

Flash memory can be thought of as the hard drive of a mobile phone. If a mobile phone slows down, it may be because the performance of the flash memory has declined, which is what people often call "speed drop". In fact, whether it is the flash memory of a mobile phone or the SSD used in a computer, they are all NAND particles. It's just that the particle type, main control chip, and transmission protocol are different, which leads to great differences in their lifespan and performance.

In the past, mobile phones commonly used the eMMC protocol, but now UFS has become mainstream. UFS is faster than eMMC and supports simultaneous reading and writing, so its speed performance is much better. To make a simple analogy, eMMC is a three-cylinder Xiali, and UFS is a Maserati. A three-cylinder Xiali runs on country roads, while a Maserati runs on a two-way highway.

Although the performance gap between the two is huge, they are both flash memory particles, and based on physical characteristics, they will experience performance degradation after long-term use. It's just that UFS is so fast that you can't feel it even if there is some degradation. This is like a 3.0T twin-turbocharged Maserati running faster than a three-cylinder Xiali even if it burns oil.

What's up with the annoying flashback?

Android phones freeze after a while, and Apple phones crash after a while. Neither is much better than the other. We won't go into details about the obvious problems of too much system memory and system garbage, which can be solved by flashing Android phones and updating Apple phones. On the contrary, the annoying crashes of Apple phones, especially those older than four years old, are also a stubborn problem that is difficult to cure.

There are many reasons for the crash, which can be roughly attributed to the following: APP compatibility, system memory, and various problems caused by the battery. APP compatibility is easy to understand. Many old devices are prone to compatibility issues when using new systems. In addition, many old users refuse to update to the new system, but the APP Store only pushes the new version, which leads to compatibility issues.

Battery degradation causes iPhone performance to drop significantly

For Apple devices, battery performance can have a very direct impact on performance. For example, the iPhone 6s era was a hot topic, with problems such as shutting down in seconds when the weather got cold, battery degradation leading to CPU frequency reduction, and a series of other problems. Apple officially launched a free battery replacement service and added battery health data to the system. If your old iPhone becomes stuck, crashes, or has a white screen, replacing the battery may be a miraculous solution.

Based on the above, we can roughly understand the truth about why the phone becomes slower and slower as we use it. In fact, to some extent, manufacturers have also played a role in making the phone slower, which is no longer a secret. We will sort out some tips to keep the phone running smoothly in the future, and I hope everyone will continue to pay attention.
