Why iPhone can achieve 4000+mAh battery life of Android with less than 4000mAh? The reason is revealed

With the continuous development of technology, mobile phones have become an indispensable tool in people's daily lives. However, as the functions of mobile phones continue to increase, their size and weight are also increasing, which is a considerable burden for users. So how do mobile phone manufacturers achieve the balance between thinness and battery life? From the perspective of the development of smart phones, there are several methods.

1. Directly reduce battery capacity

In early mobile phones, when stacking capabilities and battery cell technology had not yet made great progress, in order to obtain a thinner and lighter appearance, additional battery capacity was usually obtained by reducing battery capacity. fuselage space, thereby reducing body volume. Among them, the most famous one is the mobile phone that can be used for a day.

2. Optimize the internal structure of the mobile phone

The solution of directly reducing the battery capacity has limitations. The key to truly solving the problem lies in optimizing the internal stacking. By adopting more efficient circuit designs, thinner screens, and more compact internal layouts, mobile phones can be made thinner and lighter without reducing battery capacity.

For example, Apple used an OLED screen and a double-layer motherboard design for the first time in the iPhone X, which effectively reduced the space occupied by the motherboard inside the fuselage, allowing the iPhone of battery.

Improve battery density

As major brands pursue the development of images, performance, battery life and other aspects, the motherboard space is occupied by CMOS sensors, and the battery capacity is stretched. Improving battery density has become key.

This year, silicon-carbon anode battery technology has made a breakthrough, significantly increasing battery density. Various companies have launched large-capacity batteries. Ultra-large batteries of 5000mAh, 5500mAh, and 6000mAh have become popular, with almost the same size, taking into account thinness, lightness, and battery life.

New direction in the future: improving the level of software and hardware electronic control

Large batteries are popular, but consumers find that battery life is not absolutely linked to battery capacity. The main reason comes from software and hardware.

Hardware: Improved imaging capabilities, multiple cameras can be turned on at the same time, and the power consumption is higher than single camera and dual camera. The level of CMOS technology has been stagnant for a long time.

For example, the one-inch outsole IMX989 uses a 40nm process. This may not be backward in the field of cameras, but it is not advanced for mobile phones that have to pay attention to efficiency everywhere. Until this year’s iteration LYT- The 900 has only been replaced with a new 22nm process, and the energy efficiency ratio has been improved.

In addition, the gradually increasing running memory and storage space are also slowly eating up the extra battery capacity. In addition to the increasing power consumption caused by the gradual increase in hardware, in the final analysis, it is also caused by the poor electrical control level of the software.

For example, when the LTPO screen was just released, many people found that most APPs in actual applications did not adapt to the refresh rate, which wasted the power consumption saved on the hardware. Many people also ridiculed - LTPO There is loneliness, and there are many software optimization problems such as difficulty in watching one core and nine cores.

There is also the excellent electronic control level of the iPhone. It only relies on a battery capacity of about 3000-4000mAh, but it can achieve the battery life of Android 4000-5000mAh. This tells us how much room for improvement there is in electronic control.

Written at the end

The balance between thinness and lightness and battery life is a relative concept, and the needs of different users need to be taken into consideration.

When achieving the balance between thinness, lightness and battery life, the best balance effect can be achieved by optimizing the internal structure and electronic control level of the mobile phone. Now different mobile phone manufacturers have adopted different strategies when pursuing the balance between thinness, lightness and battery life.

vivo has reduced the weight of mobile phones without sacrificing battery capacity by using new batteries and optimized designs, such as the soon-to-be-released iQOO Neo9S Pro+, while OPPO has increased battery capacity on the basis of the same thickness, such as OnePlus Ace3 Pro shows that OPPO attaches great importance to battery life.

As major international manufacturers, Samsung and Apple have always been at the forefront of thin and light design. By continuously improving electronic control management, they have achieved excellent battery life performance in the same thin and light size. These strategies reflect each manufacturer's understanding and choices of user needs.

With the continuous development of technology in the future, we believe that more technologies and methods will be applied to balance thinness and battery life, bringing a better user experience to users.
