In the era of feature phones, it is normal to have a standby battery for more than ten days, and users can even use it for a week without charging. At present, most smartphones have several times the battery capacity of the feature phone era, but users need to recharge once or even twice a day.
According to a survey on the iPhone's shortcomings by FixYa, a Japanese smartphone user service company, the number one reason is the short battery life, at 35%.
Lithium battery development is close to zero.
At present, the innovation rate of lithium battery materials is very slow, most of which are improved in the manufacturing process, resulting in the capacity of a lithium battery can only achieve an annual increment of about 10%.
In mobile phones, however, the trend is towards slimmer designs, which are at odds with improvements in battery capacity. At present, the weight capacity ratio of lithium battery materials is about 150mA/g. If there is no good industrial design, simply increasing the battery capacity will make mobile phones look horrible.
The eight immortals cross the sea, and each shows his magic.
The second method is for manufacturers to innovate in charging methods, such as wireless charging technology, wi-fi signal charging technology, etc., which can save users from carrying too many data cables to some extent.
Of course, if you want to fundamentally solve the problem of insufficient battery life for mobile phones, and make them thin and thin while still having a small battery inside, you can only hope for a breakthrough in battery materials. However, new types of batteries, such as fuel cells and nuclear batteries, are generally expensive, and due to factors such as immature technology and doubtful safety guarantees, it is still some time before they are truly commercially available.
The smartphone industry is growing at a blistering pace, though battery technology is improving only at a limited rate.
The second is the emergence of new smart hardware. In particular, lithium batteries still used in the vast majority of wearable smart devices that are small enough to carry around. On the one hand, in the absence of a breakthrough in lithium battery technology, the longer battery life means the larger battery size. On the other hand, because of the need to meet the "wearable" properties, these devices are equipped with batteries that cannot be too large.
How to let users experience these emerging devices no longer need to worry about the charging problem, go out the necessary mobile power, and have become a wearable smart device to break the "bottleneck."
