Why is the Android phone battery capacity getting bigger and bigger but not durable?

I believe that you and I have this kind of question: the battery capacity of my mobile phone is up to 3000mAh, and the iPhone6 is only 1810mAh, but it is not as durable as others. Why? So, let's talk about what factors determine the battery life.

1. The three main factors that affect mobile life

(1) The capacity of the density

The battery is the same as the camera of the mobile phone. It can't just look at the surface parameters. Apple's 800W camera can kill many brands of 1300W. The same is true for batteries. You can't just look at the size of the capacity, but also the capacity density.

It's like two volume of the same size bottle, one will only 10 stone, another technical cow X, crush the stone can, due to the gaps between the stones become smaller, the result can hold 15 stone and the size of a pebble.

Therefore, when buying a mobile phone, do not blindly look at the size of the capacity, but also depends on its density. At present, the density ratio of the mobile phone battery capacity is mostly around 350Wh/L, which is better than this density.

(2) Hardware configuration

Theoretically higher configurations often mean more power, such as a 1080p screen that saves power compared to a 2K screen, and a processor 4 core that saves more power than an 8-core. Of course, if some devices adopt a more advanced process, the power consumption can be reduced.

(3) Software optimization

Software optimization, it is a system optimization, such as the Android system involves the process of background tasks, etc., to make it more and more fluent, is becoming more and more.

Second, hardware algorithm optimization, such as quad-core processors, mild wake up only when using two nuclei, the only heavy use, such as play big game, only four full open, so you save a lot of electricity. Of course this requires hardware manufacturers and software developers to achieve the best effect.

2. Improve the mobile life what way

(1)Quick charge technology

Mobile phone is more and more thin, the capacity of the battery is difficult to do big, naturally quick charge technology, filling a while at this moment, can be used for a long time - this is a kind of solution.

Now not only Qualcomm, Media Tek chip manufacturers such as took out his quick charge scheme, there are also some mobile phone manufacturers have developed with independent intellectual property rights of quick charge technology, such as OPPO VOOC flash technology is good.

(2)Improve battery technology

The above-mentioned method of increasing the energy density of the battery is only a primary technology. After all, the increase in density is on the line, too much. So using a new lithium battery is a good way.

For example, researchers at Tsinghua University in China and the Massachusetts Institute of Technology recently developed a new nano-lithium battery that can be recharged in 6 minutes.

This battery is not only more durable, but also fast charging (only takes 6 minutes). In addition, the capacity of the new lithium-ion battery has also increased significantly, almost three times the battery capacity of mainstream mobile devices, which can make the phone's battery life last longer.

(3) The use of new materials

There are many new materials, such as graphene batteries and aluminum ion batteries that are very hot (not currently used). It is reported that graphene can increase battery energy density by 10% and life by 50%; aluminum ion battery is said to be able to fill a battery with a capacity of about 5000mAh in one minute.

Obviously, this new type of battery is what we really need. After all, the current rechargeable lithium battery was invented by Sony in 1992 and has not improved for a long time. Of course, the new battery looks attractive, but it's still in the experimental stage.
