What each of us has in our pockets now is absolutely unmatched by phones twenty years ago. Our flat screens are now incredibly powerful. And the work that used to be solved on a PC is now clearly handled on them. Working with documents, editing 4K videos, playing demanding 3D games, handling e-mails, or high-quality cameras. In short, the phone is, from the point of view of the past, rather such an extremely powerful pocket computer. However, in today’s thinking, let’s think about why phones have such poor battery life. Otherwise, they are really great. Why We Still Don’t Have Better Batteries?
Why do phones have poor battery life?
In the last few years, the curve of technology has begun to rise to the skies. Chipsets that have better rough performance than any office computer, great cameras. That is responsible for the end of compacts, or fantastic displays with a lightning-fast response. All of this is completely incomprehensible to individuals who have experienced playing on 386 or even the first color television. On the contrary, for millennia, such a pancake is a completely normal thing. But let’s get to today’s question – why do phones have such poor battery life?
We remember the time when we had a Nokia 3310 in our pocket, which lasted a week without a charger. And we steamed a snake on her from morning till night. This applies to virtually all phones from earlier times. True, stupid phones can’t do much. From today’s point of view, browsing the internet is funny, just like java games, which we bought for an SMS from the back of magazines. But it just lasts. If someone in a group of people said they hadn’t charged their phone in a week, it didn’t seem strange to anyone. But no one would believe you today, because it is basically impossible.
Technology is improving, batteries aren’t?
Venkat Srinivasan, director of the Argonne Collaborative Center for Energy Storage Science (ACCESS) and a battery expert, has a relatively simple explanation for this problem. According to him, Moore’s Law surpassed battery technology. This means that the performance of our phones, which logically consume more power, has improved rapidly, but the progress in batteries is not so fast. He did not mean that there had been no improvement in this field. Within a few years, the small and flat battery had managed to get much more power than ever before.
This is required by the design of the phone, which has been characterized by a thin plate in recent years. According to him, today’s technology is so ahead that before inventing further improvements for the battery, the phones will again be so much more powerful than the battery life will not improve rapidly. This is said to be because batteries are still the most widely used Lithium-ion batteries today, a technology we have been using since the early 1990s, and to a large extent, humanity has reached a certain level of how much more can be improved.
However, researchers are not idle and are researching other batteries that may appear in phones in a few years. There are discussions about solid-state or graphene batteries. However, as long as there are Lithium-ion batteries in phones or laptops, endurance will not increase dramatically. We already have the first 5nm chipsets here, and a certain Moore’s rule also applies here, which will slow down development over time, so energy efficiency will not help.
