Modern smartphone users are not always thrilled with having to frequently charge their powerful devices. Sometimes we have to do even more than once a day. Many remember that in the recent past, the phone was put on charge once in several days. What and how much has changed since 2000 for phone batteries?
As a conventional push-button phones were replaced by smartphones, users began to feel that the batteries have become “less”. Today, the battery of the smartphone is usually enough for one day use. And users, of course, wish that the phone could charge less, every few days, as it was before push-button phones.
Even created the impression of lack of progress relating to batteries of the phones. However, available data show that progress has been, and it is very large. Moreover, modern mobile technically, in a simplified representation, is a battery with a miniature screen and motherboard between them.
When comparing the 50 most popular phones, says Peter (Peter) on the resource page gsmarena.com took phone each year since 2000. Were compared the ratio of the battery capacity (in mAh) to the volume of the phones (in cubic centimeters). If you summarize the essence shown in the diagram, it shows — how many mAh you have per cubic centimeter of the volume of the digital device.
As you can see easily in 2017 this figure was seven times higher than in 2000. The green line on the chart a trend line, and it shows that this ratio grows exponentially. If earlier the phone was powered by a small battery, today it, in relation to the size of the device is enormous.
Moreover, the volume of phones grew years, since screens became more and more. And more space in the phone is its battery. Apple to enhance the capacity used his new iPhone X from two batteries, while LG uses years connected batteries in a form of the Latin letter “L”. Companies seek to maximize the battery capacity, of course, not forgetting the other important preference of users who do not want the device was too thick.
However, the bright screens of modern phones with high resolution and efficient hardware consume a lot of energy.
