Who doesn't have one or two obsolete old phones at home now! But do you remember why you retired on your last phone? In real life, for most ordinary users, mobile phones will still be used until they cannot be used before they are willing to replace them, and try to make the best use of them. The general service life of mobile phones of different price points and different qualities is also different. But no matter what kind of model has the following four symptoms before retirement, especially the last one, I advise you not to endure, completely scrap it!

Indicates that there is not enough storage space
Prompt storage space is not enough, this symptom is believed that many people have experienced when eliminating the previous old machine. At first, some small partners or not dead heart, quickly clean up the garbage in the mobile phone regularly, and then delete the downloaded videos, pictures, and finally even uninstall a variety of software that is not commonly used. In the end, it was found that this problem of insufficient storage could not be solved. In fact, this problem boils down to the fact that the operation and storage configuration of the mobile phone itself is backward, far from meeting the current software operation requirements, so instead of tossing and turning, it is better to directly replace it.
Not in scope for the upgrade
The software is not within the scope of the upgrade, this symptom Android users or feel not obvious, Apple users should be deeply experienced. Apple's iOS system will be fully upgraded every year to optimize the performance and functional experience, it will generally provide after-sales upgrade services for five consecutive years, which is an important reason for the smooth and durable iPhone. If the software system of the old machine is no longer within the scope of service, it means that its hardware, configuration, etc. have not supported the new function, even if it is not upgraded at this time, it seems to be able to be used again, but it is also on the verge of elimination.
Mobile phone screen flower screen
Different users, some people will play games with their mobile phones, some people often take pictures... But no matter who is inseparable from the screen of the mobile phone, this is the root of the normal play machine, so if the mobile phone screen is flowered, it is definitely not used. In fact, the screen and battery, these accessories are all useful, when the screen appears to be a flower screen, it may be a problem with the internal circuit, or it may be a problem with the screen itself. The price of changing the screen is generally not too cheap, and it is useless to spend a high price to change the screen, so it is better to change the screen directly.
It is useless to stutter often and clean up often
These two years will always hear the word "excess performance", in fact, which users will really feel excess performance, who does not want to use three or four years are smooth and not stuck, but there are not many models that can be done, especially open source Android mobile phones. With the continuous accumulation of data, the pressure on mobile phone operation will become more and more intense, if there is a frequent stuttering, even if it is useless to clean up garbage and data frequently, it means that the hardware is really not enough. In this case, no matter how new the screen is and the camera is good, it will not play a good experience and will be completely scrapped.
The author's last mobile phone is actually Caton retired, buy something with a mobile phone to pay for half a day, often after clicking the software program to wait a long time to load the reaction, very waste of time. Later, although I changed to a new machine that is not expensive for a thousand yuan, the experience is completely different, and I admire the speed of mobile phone iteration technology! What other retirement symptoms do you think there are on the phone?
