Apple recently apologized to the recent over-hyped apple battery door, apologizing to consumers to draw the next period.According to the announcement given by Apple, the whole thing is the battery aging back pan.
Cell phone battery aging is already common sense, basically we use the battery of electronic equipment usually two or three years should die. So why the original battery two or three years on aging? And today we talk about battery aging those things.
The principle of the battery
Batteries this stuff is not a new technology, we think the first real sense of the battery is 1800, then should be the era of Qing Jiaqing (that is, his son Qianlong), it is estimated that the vast majority of the time Chinese do not yet know what electricity is.
The main battery is the use of chemical reactions will be stored in the process of electrical energy, after many years of evolution, the battery performance and capacity are also getting worse.
Our current digital products are usually used in mobile phone lithium-ion rechargeable battery, the battery anode is a lithium ion compound, the cathode is mainly composed of carbon.
When charging, the lithium ion moves from the anode to the cathode under the action of external voltage. In use, the electrons are transferred from the cathode to the anode, thus providing energy to the electronic device.
Lithium-ion batteries are light weight, small in size and large in battery capacity, and have a good environmental adaptability. They can be used normally at -20 ° C to 60 ° C (it is said that the process has been improved to -45 ° C).
At the same time there is no memory effect of nickel-metal hydride batteries, with the use of charge, there is no complicated charging process, the use of more convenient. It is also because of these advantages, so that lithium batteries become the most suitable for digital electronic products battery.
Battery aging
Everything has its life expectancy, along with the battery also has the problem of battery aging, Apple this time the cause of the storm official saying is the battery aging. So why the battery aging problem? This also talk about the principle from the battery.
After all, when the battery is working, the internal is a chemical reaction that has been charged or discharged all the time, and inevitably consumes during the chemical reaction.
There are studies in the United States show that the process of battery use, One after another of lithium-ion will be 'locked', so the battery capacity will become smaller and smaller . At the same time, the path of lithium-ion batteries will gradually be blocked by obstacles, which will make the battery performance and stability declined.
Canadian battery test analysis company Cadex research said that 'a greater threat to the battery is its internal numerous chemical reactions produce some metal free material, this metal material will be in the negative a lot of accumulation, at the same time there will be positive A small part of the aggregation eventually lead to the formation of a metal coating on both poles, which is extremely unfavorable for the battery work.
In general, the lithium-ion battery in our mobile phone can have more than 80% of the battery capacity after five to six hundred times of charging and discharging. It is worthwhile to charge and discharge one time from 100% light to 0%, which is once cycle. Therefore, we use the frequency of a day a full charge, about two years or so the battery will age about 20%.
In the face of battery aging we should do
Cell phone battery aging is inevitable, but the current technology has been able to produce longer life and better battery devices, but the cost has become a big problem.
At present, consumer electronics products are moving toward the slim, cheaper and cheaper price direction, you want the cell phone battery light and standby time enough for everyday use, then sacrificing the battery life is no solution.
We usually come into contact with the battery is inevitably in the process of aging, we can not stop him from aging, can only slow down the battery aging speed. Here to introduce some battery care tips.
First of all, We are now the cell phone batteries are lithium-ion, and no memory effect does not mean every time the phone is depleted before charging, as much as possible in the phone there are twenty percent of the power under the condition of the charge, because Cell phone battery is calculated by the number of cycles, this can greatly reduce the battery loss.
In fact, you may have to worry about, our cell phone charging circuit has long joined the protection mechanism, when the phone battery is fully charged, it will not be charged to the battery, Usually use the power supply to the phone directly, so that the life of the phone battery has no direct impact.
Another for the fatal cell phone battery injury is the temperature, Cell phone use is the heat of mobile phone battery life is an important reason.
Sometimes we play the game will plug in the power, so the phone will be much larger fever. In addition, direct sunlight, with a protective cover is not enough heat and other conditions can cause abnormal cell phone fever, will bring no small impact on battery life.
iOS users can use a battery life APP to check their cell phone consumption (I checked my phone, with more than two years of iPhone 6Plus battery has been depleted by 25%)
PS: At present Apple's official overcharge protection for the iPhone 6 and later models (including iPhone 6 / 6p, iPhone 6s / 6sp, iPhone SE, iPhone 7 / 7p) offers a discount for battery replacement activities, with the old model Batteries can not switch the battery for a friend now!
Write in the end
This time the Apple frequency down gate event, Apple officials have been given a solution, and soon after the system will be able to lift the impact of the downside, while reducing the price of battery replacement, the domestic 218 yuan to replace the original battery.
But more worthy of our concern is the cell phone battery maintenance issues, in order to make our phone can be used longer, more comfortable with the daily use of the process have to pay attention to some tips to use.
