What has happened since 2000 with the batteries of telephones?

Modern smartphone users are not always enthusiastic about the need to often charge their powerful devices. Sometimes you have to do it even once a day. Many people remember that even in the recent past, phones were put on charge once every few days. What and how much has changed since 2000 for telephone batteries?

As ordinary push-button phones were replaced by smartphones, users began to feel that the batteries were “less”. Today, the battery life of a smartphone is usually enough for one day of use. And users, of course, would like the phone to be charged less often, every few days, as it was before with push-button phones.

There is even the impression of a lack of progress regarding battery cells. Nevertheless, the available data show that there has been progress, and it is very large. Moreover, the modern smartphone technically, in a simplified presentation, is a battery with a screen and a miniature motherboard between them.

When comparing the 50 most popular phones, notes Peter (Peter) on the pages of the resource gsmarena.com , phones were taken each year, starting in 2000. The ratio of battery capacity (in mAh) to the volume of telephones (in cubic centimeters) was compared. If we briefly outline the essence of the diagram, it shows how many mAh are per one cubic centimeter of the volume of the digital device.

As you can easily see, in 2017 this figure was seven times higher than in 2000. The green line in the diagram is the trend line, and it shows that this ratio exponentially grows. If before the phone was equipped with a small battery, then today, with respect to the size of the device itself, it is simply huge.

Moreover, the volume of phones with the years also grew, as the screens became more and more. And more and more space in the phone takes his battery. Apple to increase capacity has used two batteries in its new iPhone X, while LG has used batteries in the form of the Latin letter “L” for years. Companies strive to maximize the battery capacity, while, of course, not forgetting about another important preference for users who do not want the device to be too thick.

However, the bright screens of modern phones with high resolution and productive hardware consume a lot of energy.
