How long does an electronic device last?

Nowadays, electronics such as smartphones, computers, TVs and others are increasingly part of our daily lives. In light of this, a concern arises: How long does an electronic device last?

In this article, we mention the main categories of electronics and appliances, indicating what you can do to preserve them for longer. Check out:

Scheduled obsolescence

Before starting, it is important for us to explain a technique that looks like a conspiracy theory, but which has already been proven and used by some companies: the Scheduled obsolescence.

This term refers to the practice of intentionally designing a product with a more limited useful life or with features that make it obsolete after a certain period of time, with the aim of encouraging early replacement and increasing sales.

A famous case in the industry involved the manufacture of traditional incandescent light bulbs, being considered the first case of the formation of a world business cartel in history. In 1924, the Phoebus cartel, composed by General Electric, OSRAM, Theta and even Philips decided that the lamps they manufactured would no longer have an indefinite life and would be limited to 1.000 hours. In fact, there were already lamps that lasted 100.000 hours, but they are no longer produced.

Another famous case involves the apple ipod. Made with removable batteries, it used to run for 18 months. After that, battery degradation could cause it to stop turning on, and even then, the company refused to offer any kind of support for component replacement. That is, the device had a hidden expiration date, and this fact made consumers take Apple Lossless Audio CODEC (ALAC), to justice in 2003, with a successful case.

Smartphones (cell phones)

In general, if well taken care of, a smartphone or cell phone is usually useful for at least 4 years, which is even the current deadline that some manufacturers guarantee support and system updates. And here comes the first tip: keep your cell phone always up to date.

A battery is also another limiting factor. Generally, cell phone batteries made of lithium ions usually last at least 2 years. After that, they start to degrade, reducing the total duration. And they can also degrade in advance, if you have the habit of leaving your cell phone in the sun (too hot) or snow (too cold). Therefore, always protect your cell phone from temperature extremes. And if the battery starts to inflate, it is a sign that you should run to a technical assistance.

It is also important to check whether the model has certification against water and dust (such as IP68) and, in these cases, you can wet the device, but only in fresh water (there is no cell phone that can withstand salty sea water).

To protect casing and screen, use protective cover and film. They help extend the life of the device. Finally, beware of generic chargers and cables. Always prefer original components or those of good origin.

Tablets

Logic for tablets follows the same pattern explained earlier in our smartphone topic. We have its useful life defined from the quality of its components, such as the power of the processors and the capacity of its RAM memory. As with cell phones, the more we demand close to the maximum processing capacity of the device, the greater its degradation and, consequently, the faster problems begin to arise through crashes.

The material of its finish has a clear difference between more expensive and entry-level models, making its resistance to impurities or water a greater or lesser problem depending on how much was invested in the purchase of the device. In addition, we must take into account that software may stop receiving updates for older models, focusing only on the newest tablets on the market, as well as their operating systems.

Desktop PC

The PC is perhaps one of the items that is more complex to assign a single integer value that translates the average useful life of the equipment. Its modular feature, with components chosen according to the user's taste, make this calculation somewhat complex — it would be possible to write an article just listing the useful life of each piece of the computer, such as processor, memory, motherboard, power supply and others.

The lifespan of a PC—and its components—varies with usage. In more common applications, such as internet browsing, media consumption and productivity programs, such as the Microsoft 365 and Google Docs suites, the tendency is for the PC to last longer than machines built for high-end games or large video editions. , which demand more and more capacity with each new generation.

For those passionate about games, it is an even more complex calculation because a GeForce GT 8800 2007 still manages to run games with simple graphics and mechanics such as Undertale. With this in mind, it is possible to define a useful life of approximately 8 years for a top-of-the-line Gamer PC, where this time is defined by the average time that developers will take to migrate their games to new engines, resulting in an exchange of parts .

Notebook (PC and Mac)

The notebook, by definition, which is nothing more than a portable computer. However, its compact feature makes manufacturers consolidate several components into one, preventing upgrades from being made in this type of computer. The only improvements that are usually possible in notebooks is the increase in RAM and storage capacity.

The lifespan of a notebook computer can vary depending on many factors, such as the build quality, use and care given to the device. On average, a good quality notebook can last 3 to 5 years, but this is not a fixed rule. As with smartphones, notebooks can be classified into quality categories between entry, intermediate and premium, and this will directly influence the build quality of the device, possibly extending its operating time.

As with smartphones, technological advancement is an important factor to take into account, precisely because it is not as simple to upgrade as we do with PCs. As programs and applications demand more hardware resources, an older laptop may not be able to handle these demands, which can limit its usefulness.

Finally, the way your notebook is used and cared for can have a significant impact on its lifespan. If subjected to extreme conditions such as excessive heat, humidity or frequent drops, this can shorten its lifespan. In addition, regular cleaning, adequate protection during transport and the use of a cooling pad can help extend the life.

• How to care for the product to last?

Television (Smart TV)

The lifespan of a Smart TV may vary depending on many factors, including the quality of manufacture, use and care given to the device. On average, a smart TV is expected to have a lifespan of approximately 7-10 years. However, some may last longer, while others may have problems before that time.

It is important to remember that the estimated useful life does not mean that the device will stop working completely after this period. Rather, it refers to the time the TV is designed to operate properly and reliably. After the estimated useful life, it is possible that it will start to have problems, such as malfunctions, display panel wear, or incompatibility with new applications and features.

Another factor that must be taken into account is the type of screen that the Smart TV has:

• LED screens are expected to last between 40.000 to 60.000 hours at near maximum brightness, that is, 4,5 to 6,8 years — if you watched 24 hours a day. As this is not the case, this term can reach 13 years. (Note: this category also includes QLED, QNED and NanoCell variations)
• Already OLED screens, which do not rely on a backlit panel, have a longer lifespan. According to LG, OLED panels lose brightness over time, and brightness is expected to drop by half in an amazing 54 years - possibly some other component will fail before the panel. However, the burn-in effect can leave undesirable marks on the screen, shortening the life of the TV.

Soundbar/Home Theater

The soundbar has been introduced to the market in recent years as a more practical and efficient replacement for home theater systems, and there have been many scenarios where consumers report that it lasts up to a decade, which may be feasible, given that traditional soundbars They last up to 30 years if well cared for.

The age of the device always depends on the quality of the brand. The shape and design of the soundbar also heavily influence the performance of these audio devices. If you have one from a premium brand, it will easily outlast a basic brand made with lower quality materials.

Finally, usage also affects the lifespan of the soundbar. If used sparingly and carefully, avoiding overloading the speakers or exceeding recommended volume limits, it will likely last longer. Excessive use and playing audio at high volumes for extended periods of time can cause premature component wear and shorten the life of your device.

Bluetooth sound box

The speakers usually have a good durability if kept under the care of its user, and can have a very long useful life depending on its quality. A JBL bluetooth speaker, which is a quality reference in the market, can last up to 20 years with good maintenance, but don't expect to see such a long life if you bought your device at the train vendor for 10 reais.

The durability of a speaker depends on some factors of its construction, one of them being the battery, which in turn has its own useful life. Such durability can be impacted by the way of use and even the temperature of the environment where the speaker is inserted. Good quality cases use Lithium Polymer batteries, which are built to last for years. On the other hand, if your device is of low quality, it may have a battery made of cheap material and in a short time present a reduction in capacity with the speaker running out more quickly.

Refrigerator and Freezer

A refrigerator and the freezer are perhaps some of the most important appliances on this list, and they were a real revolution in people's lives when they started to be popularized. So that we don't have to live like our ancestors without adequate refrigeration, it's important to be aware of some signs that the useful life of the equipment may be coming to an end.

The increase in the energy bill is probably one of the first factors that will be noticed after many years of use. If there has been no change that affects energy consumption (such as a change of season, when air conditioning equipment is used more often), suspect the refrigerator. Over time, the engine will wear out (which affects its efficiency), loss of coolant gas charge may occur, the seals may be compromised and even the insulation of the cabinet may be affected. Also check that the equipment is not freezing beyond what is necessary, indicating problems with the thermostat sensor.

The lifespan of a refrigerator can vary depending on many factors, including the make, model, build quality (stainless steel models better preserve the cabinet from corrosion), use and care taken. In general, a refrigerator is expected to last between 10 and 20 years. However, some high-quality, well-maintained models can last up to 25 years or more.

Stove and microwave

O stove and the microwave are essential in our day-to-day life and because of this, there is a need to be aware of their useful life and the best ways to prevent possible defects that arise after years of using your equipment. The lifespan of a stove or microwave can vary depending on many factors such as brand quality, proper use and maintenance, and more. On average, a well-maintained stove of good quality can last 10 to 15 years and a microwave 6 to 10 years.

However, mistakes are made and some of them can cost your device years of operation. For example, we all know that we cannot put metal inside the microwave oven, as the metal will reflect electromagnetic waves, preventing the food from heating up and preventing the device from working properly. But it's not just metal that we should be aware of, there are several other materials that are not advised to heat up inside the appliance and that includes aluminum, styrofoam and some pots like butter and containers of specific materials.

Air conditioning

The lifespan of an air conditioner can vary depending on many factors, including the quality of the equipment, frequency of use, proper maintenance and the environmental conditions in which the unit operates. On average, a well-maintained air conditioner can last between 10 to 15 years.

If used only at night or on very hot days, an air conditioner can last up to 30 years depending on the quality of the material used in the manufacture of the device. While in companies, there is a tendency that it lasts much less because the air conditioning remains on all day and every day, regardless of whether it is hot or cold, thus generating greater wear on its parts.

In addition, there is technological obsolescence in these devices as well. The emergence of more modern air conditioners, which offer greater energy efficiency and savings on the electricity bill, has led people to replace their old appliances more quickly. This means that, currently, there is a tendency to reduce the time of use of the same air conditioner.

Washing machine and/or dryer

As with other essential household appliances, it is essential to pay attention to washing machine maintenance. This is important both to avoid problems with its operation and to preserve the integrity of the clothes during the washing process. On average, a well-maintained washing machine can be expected to last between 10 to 15 years. However, some high-quality, properly maintained machines can last up to 20 years or more.

When close to the end of its useful life, the device can waste water excessively, causing an increase in water and energy consumption, in addition to a drop in its performance with clothes that are not as clean or not as dry as they should be. It is also important to pay attention to the panel, which is one of the most sensitive parts of the device and must be given extra attention to maintain the integrity of the machine.

Blender

The blender is a very versatile appliance and is present in several Brazilian recipes. With the ability to help process an ingredient and at the same time make a beautiful juice, this item has become a must-have in every kitchen. However, like everything else in life, the blender comes to an end and some of the signs that can make it clear that it is time to change equipment begin to emerge and it is important to know how to identify them and understand how we can make it last longer.

Smell of smoke and loss of power are among the main signs that the blender can provide for the user to know that it is time to replace it. After use, sometimes we can smell a burning smell, which can indicate overheating of the insulating material inside the motor and this can leave it exposed to burn very soon. So, like when we are trying to prepare a recipe and we realize that the appliance is not delivering good results, often leaving pieces of food or even crashing and not being able to process the ingredient.

The useful life of the blender will vary according to the brand and model, as different types use materials of different qualities, which can increase or decrease its durability. On average, a good quality blender is expected to have a lifespan of approximately 5 to 10 years. However, it is important to remember that this deadline is only an estimate and there may be considerable variations.

Traditional vacuum cleaner and robot vacuum cleaner

As with a blender, the lifespan of a vacuum cleaner can vary depending on many factors. Product quality, type of engine, frequency of use, proper maintenance and care when using it are some of the aspects that influence its durability.

On average, a good quality vacuum cleaner is expected to have a service life of approximately 8 to 12 years. However, this estimate can vary considerably. Some cheaper or lower quality vacuum cleaners may wear out more quickly, while other well-cared for models from well-known brands can last beyond this period and, in the case of robot vacuum cleaners, the service life lasts approximately between 3 to 5 years .

Some clear signs that your device is not working properly are loss of efficiency, noise level greater than normal, instabilities in operation with the vacuum cleaner turning off by itself, bad smell or smoke signal during use and, for those using battery , there's also the issue of the battery not holding a charge properly. In the case of the last problem, we must pay extra attention because the price of a new battery can be equivalent to 50% of the value of a new robot in some cases.

fuel car

The useful life of a car and its depreciation are hotly debated topics because of all the items on our list, the vehicle is probably the one that suffers the most from resale after use. Most of the time, when a buyer wants to buy a new car, he just discards the old one. Because of this, it is important to know how much commercial value that car has lost since its purchase.

In general, modern cars are designed to last a long time. With proper maintenance and regular care, many cars can easily exceed 200.000 kilometers and some well-maintained vehicles can reach 300.000 or even 400.000 kilometers. However, it is important to mention that there are parts and components in a car that naturally wear out over time and need to be replaced regardless of maintenance. For example, the clutch, brake pads, tires and belts usually have a limited lifespan and need to be replaced periodically.

Furthermore, automotive technology is constantly evolving, and older cars may eventually experience issues of technological obsolescence, where certain features or systems may become outdated or difficult to repair.

Electric car

The lifetime of an electric car can be influenced by many factors, but in general, an electric car is expected to have a similar or possibly longer lifetime than an internal combustion engine car. Batteries are an important component that plays a crucial role in the lifespan of the vehicle and modern electric car batteries are designed to be durable and have a projected lifespan for many years of use. Most electric car manufacturers offer long-term warranties on batteries, generally ranging from 8 to 10 years.

With proper maintenance, such as carrying out proper charge cycles and avoiding temperature extremes, it is possible to further extend the useful life of electric car batteries. Furthermore, the continued advancement of battery technology is leading to improvements in durability and efficiency, which could result in an even longer lifespan for electric cars in the future.

However, it is important to note that over time, the capacity of electric car batteries can gradually decrease due to natural wear and tear. This means that, over the years, you may need to recharge your vehicle more frequently or cover shorter distances on a full charge. However, even when the battery capacity decreases, the electric car can still be perfectly usable for many purposes, such as commuting.

In addition to the batteries, the other components of an electric car, such as the electric motor, power electronics and auxiliary systems, are also designed to have a long service life, often requiring less maintenance than their internal combustion vehicle counterparts.

Camera

In general, modern cameras are designed to last for many years, especially if they are well cared for. Digital cameras tend to have a longer lifespan than analog cameras due to their more robust electronic construction and lack of mechanical moving parts. However, even digital cameras can eventually experience wear and tear and technology-related issues such as hardware obsolescence or incompatibility with updated operating systems.

It is difficult to establish an exact number of years for the useful life of a camera, as it can vary greatly. Some professional photographers use their cameras for many years, while others may choose to update their equipment more frequently to take advantage of new technologies and features. One of the points that we can use to determine the lifetime of the camera is how many clicks the shutter of the equipment can perform, which can vary between 100.000 to 400.000 clicks depending on the quality of the model.

In short, we can say that the useful life of all the equipment on our list will directly depend on the quality of its components and how each user will take care of it. Did you like our tips and are you going to use them to make your electronic devices last longer? tell us us Comment!
