The smart phone is better than the previous phone, and the phone battery is too weak. Apple phone battery endurance is particularly evident. Why is the battery endurance of mobile phone batteries not improved after so many years of development? We still need to charge it once a day or even twice a day. Indeed, after years of development of smart phones, battery endurance has become a chronic problem in the industry.
The performance of smart phones improves, battery power is greatly increased
In the era of feature phones, using more than 10 days is normal. Users needn’t charge for a week. At present, most smart phones have far more capacity than the feature phones in terms of battery capacity, but users need to charge one or more times a day.
The reason is that the development trend of smart phones tends to be more and more functional, the performance is getting stronger, and the screen is getting larger, which leads to a significant increase in the power consumption of mobile phones.
According to a survey on the iPhone’s shortcomings by Japan’s smartphone user service company FixYa, the number one ranking is Apple phone battery endurance. The proportion reached 35%. It can be seen that the lack of battery endurance of smart phones has become the biggest pain for users.
Lithium battery development is approaching the limit
The reason why mobile phone battery endurance can’t be qualitatively changed is that it can only rely on the development of lithium-ion batteries, but the speed of lithium battery upgrades is far behind the growth rate of smartphones’ demand for batteries.
At present, the rate of innovation of lithium battery materials is very slow, and most of them are improved in manufacturing technology, resulting in the lithium battery capacity can only achieve an increase of about 10% per year.
Even Elon Musk and Tesla, who are known for their breakthrough innovations, have only made breakthroughs in battery management. They have not made any progress in the materials and technology of the battery itself, and still use the traditional Panasonic lithium battery.
