Does Apple phone turn off frequently? Look at the doorway behind the lithium battery.

A few months after the launch of the iPhone 7, rich friends are starting to lose control of their hands and are ready to give generously. Some people say that when the new iPhone comes out, the old iPhone will soon become unusable! This must be Apple's plan!

More recently, the iPhone 6 and iPhone 6s 'shutdown doors' have been fermenting for some time, and the Chinese consumer association has stepped in to push Apple to the top.

The last month or two since the shut-down door burst, the iPhone 6 and iPhone 6s series of mobile phones occurred in the event, the performance of 30 % of the remaining power when the automatic shutdown, upgrade system brushes or other useless, without connecting the charger can not open the machine. It is said that even 50 % -60 % of the electricity will be automatically turned off.

Does it make sense that the temperature is "pot man" Apple?

Initially, Apple interpreted the "shut down door" as affecting battery capacity at low temperatures, and even published a description of "Running the iPhone, iPad, and iPod touch at the right temperature"(which sounds complicated), the article said. Users need to run IOS devices between 0 °C and 35 °C. In an environment below 0 °C, the battery service time may be temporarily shortened and automatically shut down.

In fact, the low temperature can actually cause the lithium battery performance to decline automatic shutdown. Let's look at the discharge principle of lithium batteries:

At low temperatures, the resistance of lithium ions in the battery to transport in positive and negative solid particles increases, and the state is probably this:

When this state is reached to a certain extent, the output voltage of the battery will be greatly reduced. The iPhone, like some relatively high-end electronic products, automatically shuts down the monitoring chip as long as the actual voltage output of the battery is lower than the specified voltage. In the cold north of China, lithium-ion batteries do not work properly from time to time, so it is not a joke to heat the camera with a warm baby when taking photos.

At low temperatures, the user charges the lithium battery, and the lithium ion nested on the negative pole produces ion crystals that may pierce the diaphragm. In general, a micro-short circuit affects the life and performance of the lithium battery. Therefore, even normal lithium batteries, It is inevitable that "dark disease" can occur many times under low temperature. So this is particularly true for the iPhone 6 and 6s after a year or two.

So why would there be a problem with the iPhone, or not? This is because lithium batteries are too active and consistency will become poor. Even products of the same batch, same material, and the same process will have very different performance.

Whose fault is it to "suffer" in the light of "occupy reason"?

Perhaps Cook is very depressed, clearly feel that they are "reasonable", but how the end or "lost", the development of the plot is not right!

But Apple has long had a better reputation among consumers. Although this shutdown door affects the use of users, it is not as horrible as Samsung's explosion door.

So, what caused the "shutdown door" to become more and more intense?

What is wrong is not "truth", but the way to speak "truth".

First of all, Apple made the so-called "explanation" in the first place, but did not propose a solution(or reliable after-sale), so that consumers have this feeling:

Second, it was later "forced" to agree to replace the problem battery for free, and only to replace some of the iPhone 6S. But it's not just the iPhone 6s that's going wrong, it's the iPhone 6. Only replace some batches of iPhone 6S batteries, so the user with the problem iPhone 6 ...

This behavior undoubtedly implies that Apple believes that these iPhone 6 problems are due to normal battery wear and tear. That logic suggests the same "normal wear and tear" that could occur a year from now if Apple doesn't replace a batch of iPhone 6s, and two years from now the iPhone 7.

This partial solution is similar to the previous Samsung Note 7 China does not recall the same, is to dig a pit to jump. Apple's sales have a declining trend, through Samsung's explosion door's "God assists" did not show a tendency to decline, this is good, digging two pits at a time to jump off without shouting for help, who will agree with Apple again?

In the end, Samsung and Apple are not the two dominant high-end markets. After Samsung's explosion, Apple made another mistake. I don't think Huawei, Xiaomi, MOTO and so on will miss this once-in-a-lifetime opportunity. Into the high end of the market.
