Is the battery of Apple mobile phone durable when it is cold?

Despite the arrival of winter, I believe that many netizens' Apple phones have started to turn off automatically in a low temperature environment. Fear of cold is an old problem of Apple's mobile phone. In the past, the size of Apple mobile phones was not large, so the battery capacity was relatively small. The characteristic of lithium battery is that the capacity will shrink seriously in cold weather. Netizens who drive electric cars should have a deep understanding that the same car can run 200 kilometers in summer, but it may not run 100 kilometers in the coldest winter. The battery capacity of Apple mobile phone is naturally far less than that of electric car, so it will be more affected by temperature. Apple's mobile phone processor is very sensitive to battery discharge. Once the battery power fails to meet the requirements of the processor, the phone may automatically restart. Therefore, in previous generations of products, Apple strictly stipulated the applicable temperature range of mobile phones. When the sensor in the mobile phone detects that the ambient temperature is too low, the mobile phone will automatically turn off.

In addition, charging the mobile phone at low temperature is likely to affect the life of the mobile phone, so the Apple mobile phone often cannot be charged normally after it is automatically turned off at low temperature. At this time, you must take the Apple mobile phone to a warm room, and then turn it on and charge it after the body temperature rises. However, three Apple phones listed this year: iPhone.

XS, iPhone XR and iPhone XS Max may be more "cold-tolerant" than their predecessors. Because from the iPhone

Since the XS generation, the screen size of Apple mobile phone has been between 5.8 inches and 6.5 inches, which is much larger than the previous 4.7 inches, and the battery capacity has also increased. Including the iPhone.

The battery of XS reaches 2568mAh, that of iPhone XR reaches 2942mAh, and that of iPhone XS.

Max's battery has reached an astonishing 3 174mAh. Although the battery capacity of these three new Apple phones is still not too large compared with the Android phones of the same period, they have made great progress compared with the past.

With the increase of battery capacity, the sensitivity to temperature will also decrease, at least in low temperature environment, the battery shrinkage is not as obvious as before, and the probability of automatic shutdown will also decrease. Therefore, the three new iPhone should not be as afraid of cold as the old ones.

In addition, in iOS,

In the later version of 1 1, Apple added the "peak performance capacity" option to the battery health settings. When the mobile phone is turned off unexpectedly due to insufficient battery power, the "performance management mode" will be automatically turned on. At this time, the processor of Apple's mobile phone will automatically reduce the demand for battery power to avoid accidental shutdown again. But in contrast, Apple phones in performance management mode will get stuck because of processor frequency reduction. If netizens often need to use their mobile phones outdoors in winter, don't turn on the "performance management mode" option. After all, it's better to have a mobile phone card on than not to turn it on at all.
