Why is the autonomy of smartphones so small?
Mobile phones have improved significantly in the last decade. Modern smartphones – θήκες κινητών – look like they came from another planet if you place them next to a regular mobile phone.
smartphone from another planetThe autonomy of their battery, however, has not improved much. In fact, not only does it not increase, but on the contrary it is constantly decreasing.
The old classic phones could work for a week or more with a full charge, unlike modern smartphones which can hardly last a whole day!
Battery technology is not improving enough
The truth is that we are accustomed to dramatic developments in technology. Processors, memories, monitors and other components are improved in performance, speed and production costs.
mobile phone developmentThey offer more computing power, capabilities and analysis in terms of cost and value for money.
Likewise, smartphones today have faster processors, more storage space, more memory and higher quality screens than ever before.
The difference between a smart phone today and one that was released a few years ago is huge.
However, battery technology is evolving very slowly.
For example, while other components are shrinking in size, batteries still occupy a respectable percentage of a phone’s internal space.
And this is not expected to change significantly in the coming years.
Emphasis on design
The technology of the batteries shows some improvement, although small, while at the same time the components of the smartphones become more efficient, which means that they consume less energy.
However, there is no significant improvement in the autonomy of the phones. Why is this happening;
Modern smartphones with Android, iOS, etc., are becoming thinner and lighter. This has a negative effect on battery life.This is because instead of focusing on maximizing autonomy, manufacturers are investing in minimizing battery size in order to shrink the size of phones as much as possible while increasing performance.
Both of these elements reduce, or rather do not increase as much as possible, the autonomy of smart phones.
Each subsequent model (either iphone, samsung galaxy etc) is thinner and lighter than the previous one with longer battery life.
However, this does not mean that it could not have improved even more if the company had chosen to maintain the same thickness as its predecessor.
But most smartphone makers choose to make a thinner and lighter phone.
In addition, larger batteries are more expensive because they contain more materials.
Therefore, shrinking the batteries also helps to minimize costs. Another big issue is access to the phone battery. Once upon a time, a spare, or more efficient, battery was an option.
Last but not least, as more and more companies (Apple, Alcatel, etc.) make phones with batteries inaccessible to the user.
Updates and synchronization in the background
A classic phone had minimal features. The user did not receive constant notifications about new emails, social media updates and so many other instantly updated information.
It did not automatically check for app updates, since there were no apps, it did not download new weather forecasts, nor did it constantly update the user’s location or anything like that.
Modern smartphones are essentially like computers. In fact, even the same software is running.
Android technology uses linux, iOS uses Darwin, and Windows Phone 8 uses the Windows NT kernel used by Windows on desktops. The screen of a mobile phone can be inactive, while the phone itself can be active and busy.
On Android devices, where applications have much more freedom, various programs can run in the background, consuming computing power and of course battery.
Apple’s iOS restricts apps much more, but does not prohibit updates and synchronizations that also consume a lot of battery power.
Larger screens, faster processors, more cores and LTE receivers
Value for money can be improved over time, but at the same time much more powerful hardware is used in the phones.
Every year, screens get bigger and higher resolution, processors get faster, and more cores and LTE receivers are added to most phones.
LTE wireless technology
Although LTE allows faster data transfer than previous 3G technology, it requires, as expected, more battery power.
In addition, there is generally a lot more hardware in a modern smartphone than in an old classic phone.
wireless networks In addition to LTE and 3G, there is Wi-Fi, Bluetooth, GPS and NFC (Near Field Communication).
The above does not have to be constant.
But when activated, they literally dry out the battery.
In summary, we can say that battery technology is not improving as exponentially as other technologies used in smartphones.
This means that a smart phone with a longer battery life requires compromises.For example we could have a smartphone with a much longer battery life, but it would be heavier and thicker.
We could also further increase battery life by installing less demanding hardware on the phone. In reality, however, the general requirement of an average user is large, high-definition and high-resolution screens and fast processors. Thus, while performance is constantly improving, batteries are unable to keep up.
