In the era of feature phones, it is normal to stand by for more than ten days, and users can use phones for a week without charging. At present, the li on cell capacity of most smartphones is several times that of the feature phone era, but users need to charge them once or even twice a day.
The reason is that the development route of smart phones tends to more and more functions, increasingly strong performance, and larger screens, which greatly lift the energy consumption of mobile phones.
This shows that insufficient li on cell life of smartphones has become the biggest shortcoming on user experience.
The reason why the li on cell life of mobile phones cannot undergo qualitative changes is that they can only rely on the development of lithium-ion batteries, and the rate of increase in batteries lithium is far behind the growth rate of the demand for li on cell in smartphones.
Even Elon Musk and Tesla, known for their breakthrough innovations, have only made breakthroughs in li on cell management, and have not made progress in the materials and technology of the li on cell themselves, and still use traditional Panasonic batteries lithium.
In the field of mobile phones, it is more special. The current trend is thin and light design, which is in contradiction with the increase of li on cell capacity.
At present, the weight-to-capacity ratio of batteries lithium materials is about 150mA/g. If there is no good industrial design, simply increasing the capacity will make the appearance of mobile phones terrifying.
Therefore, many smart phone manufacturers abandoned large-volume li on cell in order to meet the appearance requirements.
The most common solution at present is to carry a mobile power bank: Although the standby time of the mobile phone is not so long, the mobile power bank of 10000mAh can basically meet the charging needs during travel.
The second method is for manufacturers to innovate in charging methods, such as the use of wireless charging technology, Wi-Fi signal charging technology, etc., which can save users from carrying too many data lines to a certain extent.
The third method can only rely on the efforts of mobile phone manufacturers and Qualcomm and other chip manufacturers to minimize the power consumption of core components such as processors and screens, while continuously optimizing system and interface settings to extend the li on cell life of mobile phones.
Of course, if the problem of insufficient li on cell life of mobile phones shall be fundamentally solved and thinner and lighter mobile phones shall be realized with small size and large-capacity li on cell, breakthrough in li on cell materials shall be pinned hopes.
However, new types of li on cell such as fuel cells and nuclear energy li on cell are generally costly, coupled with factors such as immature technology and doubtful safety guarantees, so it will take time to truly realize commercialization.
