While all the technological features of the new generation mobile phones – θήκες κινητών – are improving significantly, the batteries do not seem to follow. Why is this happening; Let’s see!
Cell phones have improved significantly over the past decade. Modern smartphones look like they came from another planet if you put them next to a regular mobile phone.
In fact, not only is it not increasing, but on the contrary it is constantly decreasing.
Old classic phones could run for a week or more on a full charge, unlike modern smartphones that barely manage to last a full day!
Battery technology is not improving enough
The truth is that we are used to dramatic developments in the field of technology. Processors, memories, displays and other components are improving in performance, speed and cost of production.
They offer more computing power, features and analysis than their cost and value for money.
Likewise, smartphones today have faster processors, more storage, more memory, and higher-quality displays than ever before.
The difference between a smartphone today and one 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 today take up a respectable percentage of a phone’s internal space.
And this is not expected to change significantly in the coming years.
Emphasis on design
Battery technology is showing some improvement, albeit small, while smartphone components are also becoming more efficient, which means they consume less power.
Despite this, there is no noticeable improvement in the autonomy of the phones. Why is this happening;
Modern smartphones with Android, iOS, etc. operating systems are becoming thinner and lighter. This fact has a negative impact on the autonomy of the battery.
Slim smartphones
This is because instead of focusing on maximizing autonomy, manufacturers are investing in minimizing the size of batteries 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 they could, the autonomy of smart phones.
Each subsequent model is thinner and lighter than the previous one with longer battery life.
However, this does not mean that it could not have been improved even more if the respective company chose to keep the same thickness as its predecessor.
But most smartphone manufacturers choose to make a thinner and lighter phone.
Additionally, larger batteries are more expensive because they contain more materials.
Therefore, shrinking batteries also helps to minimize costs!
Another big issue is accessing the phone’s battery. At one time, a backup, or a more efficient battery, was an option.
Background updates and sync
A classic phone had minimal features. Its user didn’t get constant notifications about new emails, social network updates (did they really exist back then? :-P) and so many other instantly updated information.
It didn’t automatically check for app updates, since there weren’t even any apps, or download new weather forecasts, or constantly update the user’s location or anything like that.Modern smartphones are essentially like computers. In fact they even run the same software.
Android technology uses linux, iOS uses Darwin, while Windows Phone 8 uses the Windows NT kernel used by Windows on desktop computers.
The screen of a mobile can be inactive, while in fact the phone itself can be active and busy.
On Android devices, where apps have much more freedom, various programs can run in the background, consuming computing power and of course battery.
Apple’s iOS operating system limits programs much more, but does not prohibit updates and syncs, which also consume a lot of battery.
Bigger screens, faster processors, more cores and LTE receivers
The performance-price ratio may improve over time, but at the same time much more powerful hardware is used in phones.
Every year, screens get bigger and higher resolution, processors get faster, and more LTE cores and receivers are added to more phones.
Although LTE allows for faster data transfer than the older 3G technology, it also requires, as expected, more battery power.
Additionally, there is generally much more hardware in a modern smartphone than in an old classic phone.
In addition to LTE and 3G, however, there is also Wi-Fi, Bluetooth, GPS and NFC.
The above does not necessarily run continuously.
But when activated, they literally drain the battery.
In summary, we can say that battery technology is not improving at the same exponential rate as other technologies used in smartphones.
This means that a smartphone with longer battery life requires compromises.
