Recently, there was a news report of a couple who charged their phones overnight after falling asleep at night. The safety of mobile phones has also become a concern for everyone, and the majority of fruit fans can't help but worry about whether overcharging iPhones is also dangerous?
In fact, the current smartphone charging will have an overcharge protection mechanism, when the phone is charged to a certain amount of power, the charger will automatically switch to trickle charging mode. This mode is to continue charging the phone's battery at a lower current. This mode protects the battery life by preventing it from overheating and overcharging. (After full charge, compensates for the loss of capacity due to self-discharge).
Apple's lithium battery
We all know that iPhones use a lithium battery, which has a long life cycle and is the most widely available rechargeable battery. However, there is a limit to the number of times this can be charged, and the closer it gets to its service life, the less rechargeable capacity it can have. For this reason, Apple has designed battery health to show the life of the battery. （）
Is overcharging necessarily unsafe?
Let's talk about the impact on the battery first: the battery itself is a consumable, and after a certain number of cycles, the life cycle of the battery has arrived. Many iPhone users basically use PD fast charging, which will affect the life of the battery, the most important thing is that fast charging will bring more power heating, and the most important impact is heating.
Excessive heat will bring dangerous signals to the mobile phone, in addition to affecting the battery life, it may also bring fire, ** and other flammable phenomena. In addition, the temperature is too cold will also affect, and Apple officials have also specially introduced that lithium batteries will affect the health of the battery in extreme weather.
Generally speaking, don't use the mobile phone when it's hot, many iPhone users will have the situation of using the phone while charging, which is not recommended, in addition to being hot, the number of cycles of the lithium battery while charging and putting it is very fast, which will harm the health of the battery.
In addition, frequent charging of iPhone phones does not affect battery life, here is an explanation: iPhone phones will not affect the number of cycles because of frequent charging, and the number of cycles is affected by the situation when you use the phone. So we keep it charged and don't use the phone, and the number of cycles won't drop.
So, can an iPhone be charged overnight? The answer is yes, but we also have to pay attention to the charging problem:
Apple reminds iPhone users to be careful not to charge their phones under blankets or pillows, especially when resting, as this may cause overheating and fire. Charging suggestion: The mobile phone should be placed in a well-ventilated place, and finally, the charging equipment is recommended to be purchased through Apple's officially certified channels to ensure the user's charging safety.
Summary: We use iPhones to facilitate daily life and other operations, the battery is a consumable, the number of cycles is over, you can change the battery; The battery capacity of the average iPhone may be about 80% after 2 to 3 years, but it is actually quite long.
Therefore, paying attention to the mobile phone experience is the most real feeling of users. We mainly ensure that the safety of mobile phone use is actually fine. In this regard, what do you think about the maintenance and use of the battery? Feel free to leave a message in the comment area.
