In a world where technology advances by leaps and bounds, buying second -hand electronic devices has become an attractive option for those who seek to save without sacrificing quality.
However, this practice is not exempt from risks. Scams, devices in poor condition, damaged or with poor software are some of the problems facing those who do not know how to buy used devices.
But how to make sure the investment is worth it? What technical and security aspects should be considered before acquiring a used device?
Next, some useful tips for the purchase of second -hand technology.
The life time of used devices
Edgar Aguirre, a cell phone and microelectronic repair technician with more than 16 years of experience, explains that The useful life of a device depends largely on its use and maintenance. “In the case of the iPhone, I have seen that they have a useful life of about four to five years. Although there are models such as the iPhone 7 or 8 that still circulate, Apple usually limits its functionality over time, either slowing them down or stopping launching updates,” he says.
As for Android devices, Aguirre, who also has a YouTube channel Where he shares technical information, he points out that they usually have a similar shelf life, although they do not face the same programmed obsolescence problems. “An Android can last a little more in terms of support, but also depends on the brand and model“He adds.
For its part, Marco Antonio To, director of the Research Laboratory in Information and Communication Technologies of the Galileo University, emphasizes that The life time of a device is linked to both hardware and software. “The processors have generations, and each year they leave new. If a device is bought with a processor 10 years ago, although it works, it will not be optimal for current applications,” he explains.
In addition, he emphasizes that Operating systems have limited life cycles. “Windows 10, for example, is already reaching the end of its support, which means that you will not receive more security updates,” he warns.
To mention that there are websites, such as endoflife.date to Windows or for Androidwhere You can verify how much support time has a device remains based on your system and safety updates.
What are the most common problems of used devices?
One of the biggest risks when buying used technology is to acquire a device with hidden failures. Aguirre points out that The battery is one of the components that degrades the most over time. “A battery with less than 80% of its useful capacity is already in the last ones. On iPhone, if it is below 85%, it is likely to need to change soon,” he explains.
To and Aguirre coincide with the importance of Verify that the device is not reported as stolen or blocked by contract. “In the case of the iPhone, there is a new update that blocks the phones that are still under contract in the United States. If one of these is bought, it may not work properly in Guatemala,” says Aguirre.
To also recommend Check the physical status of the device. “If the screen is scratched, lazy screws or parts are missing, it is likely to have been repaired with non -original components,” he says.
In addition, Aguirre recommends that, before buying a used device, the price of the new device will be verified, since sometimes the cost difference is not significant. As he indicates, “suddenly, for a little more, you can find something new and with guarantee.”
Tools to verify the status of the device
For those who are not experts in technology, There are tools that can help evaluate the status of a device before buying it. Aguirre recommends application Phone Diagnostic For iPhone, which performs exhaustive tests of all components. “It’s like taking a mechanic to check a used car,” he says.
In the case of computers, to suggests Review processor specifications and operating system. “In Windows, you can access the configuration and make a hardware check. In Mac, this can only be done in an authorized service center,” he explains.
In addition, to recommend verifying in the Intel web pages and of the AMD processors If the device generation is still in force and if it will continue to receive updates.
What brands are more reliable?
Both experts agree that recognized brands are usually more reliable in the second -hand market, in addition because it is easier to find pieces if the devices need to be repaired. “Apple, Samsung and Huawei are good options for cell phones. On computers, Dell, HP and Lenovo are solid marks,” recommends To.
Aguirre adds that Apple devices tend to conserve their value better over time. “A five -year -old Macbook can still recover much of its initial investment,” he says.
Tips for selling used devices
If you are thinking of selling a used device, experts recommend investigating the market price. “Check platforms such as eBay or Facebook Marketplace to have an idea of how much your device is worth,” says To.
Aguirre adds that it is important to be transparent about the state of the team. “If the battery is worn or the device has failures, it is better to be honest to avoid problems later,” he says.
