A few days in the cold, the phone automatically shuts down the battery.
According to Battery.com.cn news, winter is coming, one to several cold days, many people find that their smart phones do not listen, not the touch screen failure, or suddenly shut down automatically. Is the current smartphone very "cool"?
The phone is "frozen" off in the cold weather
Weihai Snow Scene
Snowfall in recent days has made Weihai a world of silver. The beautiful snow scene has excited many people. People have taken out their mobile phones and took pictures. But what I didn't expect was that at the crucial moment of taking pictures, some people's mobile phones went on strike, and they couldn't wake up when they called.
In the early morning of the 19th, Mr. Jia and his girlfriend got up early and went to Yuehai Park to watch the sunrise and enjoy the snow. In order to be light, Mr. Jia just rushed out with his own mobile phone.
What he didn't expect was that the iPhone, which he usually felt very practical, began to "strike" and shut down automatically without taking a few photos. "I don't run out of battery, just press the power button to turn it on, but the result is a reminder that you need to charge." Mr. Jia said that when he got back home and plugged in the power, the phone would "slow over" and see that there is still 39% of the battery. .
Ms. Li, a member of the public, has recently been plagued by such problems. On the 20th, Ms. Li went out to work. On the way, Ms. Li wants to make a phone call to her colleagues. She doesn't want the phone to just come out. If she hasn't had time to dial, she will automatically shut down. "I just saw that there are nearly 20% of the electricity left. How did this suddenly shut down?" Ms. Li said that this is not the first time. The more urgent, the more the mobile phone drops the chain at a critical moment, which makes her Very depressed.
The phone is turned off to protect the battery
According to the battery description of Apple's official website, the lithium-ion polymer battery used in the iPhone is running at an optimum temperature between 0 °C and 35 °C. "As much as possible, the temperature of the iPhone is close to room temperature, that is, 22 ° C, which is the most ideal operating state." An official Apple authorized repairer near the city's unification road introduced that when the temperature is too low, the metal lithium in the battery is not easy. A chemical reaction occurs and a short circuit is likely to occur inside, so the iPhone will automatically shut down to protect the battery.
The official information provided by Apple shows that not only the low temperature will affect the operation of the mobile phone , but the high temperature will also affect the normal operation of the mobile phone , and even cause permanent damage to the mobile phone battery .
Mr. Liu, who is engaged in mobile phone repair, told reporters that the phenomenon of automatic shutdown of the mobile phone in the cold weather not only appeared on the iPhone, but also in other brands of mobile phones.
Mr. Liu reminded that when winter is often used outdoors, you should try to ensure that the battery is fully charged, and the remaining 30% or 40% of the power may be turned off. In addition, try to ensure that the phone is placed in the inner pocket. When using the mobile phone outdoors, you can try to use the headset to talk, so as to avoid the automatic shutdown of the mobile phone due to the low temperature.
