iPhone automatic shutdown tracking: the reason is unknown, customer service said wearing a protective case can keep warm

Recently, many iPhone users have reported that their phones automatically shut down when the battery level is between 20% and 50%. When asked by a China News Service reporter, Apple customer service staff said that they have received many reports from users about their phones automatically shutting down.

However, Apple has not yet announced a solution. Wang Yanhui, secretary general of the China Mobile Alliance, said that the reason why Apple has not officially provided a solution is probably that it has not yet accurately found the root cause of the problem.

Many netizens reported that iPhones automatically shut down and the battery level drops quickly

Recently, media reported that many users complained that their iPhone 6s frequently shut down automatically even when the battery level was shown to be sufficient. The large-scale automatic shutdowns mainly occurred on iPhone 6s and iPhone 6s Plus phones.

Now, similar problems have occurred among some iPhone 6 and iPhone 6 Plus users.

"It still had 40% battery left, and it shut down automatically without any warning." Tian Tian told China News Service that this happened to her iPhone 6 twice within a week. Recently, it has not shut down automatically as often, but the battery is still draining very quickly, dropping from 20% to only 4% in an instant.

Recently, many netizens have reported this problem. Weibo user @@万木_千帆 said, "Sometimes when taking photos, the battery turns off when it reaches 10% and it can only be turned on after charging. And it still shows the original battery level, as if it has been activated."

Apple has not yet provided a solution. Customer service said that specific analysis is needed.

As of press time, Apple has not yet announced a solution to the problem reported by the above-mentioned iPhone users. Wang Yanhui said that the reason why Apple has not officially provided a solution is probably that it has not yet accurately found the root cause of the problem.

Apple customer service staff said that the specific circumstances of a phone's automatic shutdown vary depending on each person's usage habits, and are related to the phone's usage temperature, operating habits, battery life, etc.

"The longer you use your phone, the smaller the battery capacity will be due to wear and tear and bad charging habits." The customer service staff said that frequently using non-original chargers or mobile power banks to charge your phone; or frequently making or receiving calls or playing with your phone during charging... will damage the battery and affect its stability and service life.

Cause

Because the system has not been upgraded?

Wang Yanhui believes that the probability of software system problems is relatively high. Mobile phones with such problems have basically been on the market for more than a year and may not be related to hardware.

Some netizens believe that this may be because some users have not upgraded to the latest version of the system. China News Service found on the Internet that some users reported that even after upgrading to the latest iOS 10.1.1, the problem was still not solved. Netizen 77Crisna complained on Weibo, "My iPhone 6s also became like this after upgrading to iOS 10.1.1. It usually shuts down automatically when the battery is 20%-30%."

Maybe you didn't choose the right upgrade method? Apple customer service staff suggested that it is best to download the system upgrade using the computer version of iTunes, then connect the phone to install it. Because using the wireless network on the phone to upgrade may result in incomplete firmware download, causing the phone to frequently crash after the upgrade.

Because the temperature is too low in winter?

In addition, many netizens attributed the automatic shutdown to the low temperature in winter. An iPhone 6 Plus user said that the phone automatically shut down once last winter and again this winter, both times when the camera was used outdoors.

"Temperature definitely has an impact. The mobile phone can adapt to temperatures between 0℃-35℃, and you should avoid using it for a long time at temperatures below this." The customer service staff also added that if a mobile phone is used for more than one year, the temperature it can adapt to will change, and it is recommended to use it above 5℃.

Is the temperature adaptability of the iPhone a bit too "squeamish"? Wang Yanhui believes that "in terms of temperature, Apple phones are indeed more sensitive than other brands of phones", but there are currently no relevant regulations in the industry regarding the temperature adaptability of mobile phone devices.

Can a protective case keep your phone warm? When asked casually by a reporter, the customer service staff gave a positive answer, "To a certain extent, putting a protective case on your phone can prevent the phone from shutting down automatically due to low temperatures."

Tips:

What to do if your iPhone shuts down by itself?

Apple customer service staff provided a variety of self-resolved measures: first, you can try software correction to check whether there are any abnormalities in the power usage of each application, or whether there are any applications that are not used frequently but have a high power consumption ratio; or, turn off positioning and turn on low power mode when not needed.

In terms of hardware operation, try to use the restore settings. If you do it correctly, it will not affect the preservation of important data such as photos and contacts. It is worth noting that this operation needs to be combined with a forced shutdown and restart (press the HOME button + lock screen button at the same time); in addition, on the basis of ensuring a stable network, you can download and install the latest version of the iOS system through a computer.

If the above corrections are not effective, customer service staff recommends that users go to Apple stores and official after-sales service centers for fault detection and repair, which is free during the warranty period and requires payment outside the warranty period. The authorized dealers' repair service outlets can be found by clicking "Authorized Dealers" - "Service" at the bottom of Apple's official website.
