In response to the unexpected shutdown of some iPhones earlier, Apple gave the latest information. On February 24th, Apple said that after the iPhone was upgraded to iOS 10.2.1, the number of diagnostics collected by the company showed that more than 80% of iPhone 6s devices and more than 70% of iPhone 6 devices have reduced accidental shutdowns.

At the end of last year, many users reported that the iPhone 6 and iPhone 6s phones automatically shut down when there is still 50%-60% of the power, and need to be connected to the charging power to automatically restart.

Subsequently, Apple investigated the situation reflected by users. On November 20, 2016, Apple issued a statement confirming that there are very few iPhone 6s devices that may shut down unexpectedly. It refers to equipment that only affects the serial number within a certain range and the production date is between September and October 2015. Apple promises that this part of the phone can be replaced free of charge. Apple explained that a battery component was exposed to a controlled ambient air for too long before it was loaded into the battery pack, causing the battery to malfunction.

However, some users have found that their iPhone is not free to replace the battery, and there is also an unexpected shutdown.

In this regard, on February 24, Apple stressed that this kind of accidental shutdown is not a security issue. "We are fully aware of the inconvenience caused by this problem and have been working hard to resolve it as soon as possible."

iPhone system upgrade to iOS 10.2.1, improve the battery load peak performance through iPhone software upgrade, so that the accidental shutdown situation is reduced by 70%-80%; if the accident still shuts down after the upgrade, the battery is aging, has exceeded the service life . However, even if an unexpected shutdown occurs, you can reboot without rebooting.

Apple explained that after the battery ages, the load capacity is reduced. When the mobile phone suddenly has a peak load, the chemical inside the lithium battery cannot generate a suitable voltage, and the mobile phone will automatically shut down. "Because people often use the iPhone to open many applications at the same time, especially video and game applications, the battery requirements are higher." Apple said.

However, with the increase in various types of smartphone applications, power consumption has increased, coupled with the pursuit of thin and light mobile phones, limited battery capacity, and frequent charging of mobile phones, accelerating battery aging.

Apple said the completion of 500 lithium battery charge and discharge, only 80% of the electricity. Exposure to high temperatures above 35 degrees for a long time, multiple charge and discharge on the battery is permanent damage; in the ultra-low temperature environment, some extreme conditions will automatically shut down.

Launched in September 2014, the iPhone 6 series is one of the best-selling iPhone models.

In November last year, the China Consumers Association received feedback from consumers that the iphone6 ​​and iphone6s series of mobile phones used by them automatically shut down when there is still 50%-60% of the power, and the phenomenon that the charger cannot be turned on after the automatic shutdown is not activated.

On the evening of November 16, last year, Apple issued an official statement saying that the company had learned from a small number of iPhone 6s users that they had an unexpected shutdown.

On November 20, 2016, Apple issued a statement confirming that there are very few iPhone 6s devices that may shut down unexpectedly. It refers to equipment that only affects the serial number within a certain range and the production date is between September and October 2015. Apple promises that this part of the phone can be replaced free of charge.

In December 2016, Apple upgraded the iOS 10.2.1 system. The new system automatically diagnoses the battery status and greatly reduces the unexpected shutdown of the battery.

On February 24, 2017, Apple announced that after the iPhone was upgraded to iOS 10.2.1, the number of diagnostics collected by the company showed that more than 80% of iPhone 6s devices and more than 70% of iPhone 6 devices have reduced accidental shutdowns. .
