Many fruit fans will have a small habit after buying a new phone, that is, to check the health of the mobile phone battery. This also raises the question, how much difference is there from 100% to 80% of the mobile phone?
Is 80% health a criterion for replacing batteries?
If you want to check the battery health of the Apple phone, you can find the battery - battery health and charging after opening the settings, and you can see the maximum capacity label after entering, and the percentage number at the back is the battery health ratio of the phone.
The difference between 100% and 80% health is still very big, and many users report that when they first bought a mobile phone, the mobile phone can be used for a whole day, and they can still have about 30% of the power when they go home.
But once the health level drops to about 80%, even if it is fully charged before going out, the mobile phone will not last for half a day, and the battery will only be 20%.
From the perspective of actual battery life, the health of the battery has fallen to about eighty percent, and its performance ability is not as good as fifty percent of the new machine.
Some users believe that the percentage of health may represent the maximum capacity of the current battery. For example, a 1000 mAh battery, when the health level drops to 80%, the actual battery capacity is only 800 mAh.
This understanding is incorrect, because the percentage of battery health reflects the current wear and tear of the battery after a comprehensive assessment, and is not the current maximum capacity that many people think.
Objectively speaking, the health of most users' mobile phones has dropped to about 80%, and they can consider replacing the battery or replacing the machine.
Because as long as there is no quality problem in the machine itself, most mobile phones can be used for the last two or three years before the above situation occurs.
After two or three years of use, the battery will definitely wear out quite severely, and the health will be lower, which is indeed understandable.
However, this is also a "careful machine" for Apple's mobile phone, because the percentage of mobile phone battery health is not the result of professional measurement, but the data estimated by Apple according to the algorithm, which cannot reflect the real health of the mobile phone battery.
In a word, do you want to change the battery at this time, or do you want to change the phone directly? In fact, it should depend more on your actual use experience, rather than these cold data.
Let's take a look at Apple's official statement, according to the text on the promotional color page, the core factors that affect the battery life of Apple's mobile phone are officially attributed to the increase in the chemical age of the battery.
But this argument is not scientific.
Because the chemical age of all batteries cannot be calculated based on a length of time, such as one or two years of use, although many people will use these time units when describing the age of the battery, in fact, the real measurement of the chemical age of the battery should be the cycle.
Taking Apple mobile phones as an example, the number of cycle charges in a healthy state is 500 times, and the battery life will decline significantly after that.
If we maintain the habit of charging the phone once a day, then it will take about a year and a half to use the mobile phone battery, and the mobile phone battery will enter an aging state, and the user will feel that the battery is not as durable as it was at the beginning.
Not only Apple mobile phones, but most mobile phones on the market will have similar problems, that is, after the mobile phone battery is not durable, the mobile phone will be more stuck than before.
Apple mobile phone users can clearly feel that after the health of the mobile phone is less than 80%, the mobile phone is obviously not as silky as before.
This is because when the battery health is reduced, the Apple phone will automatically reduce the core frequency of the processor, and the performance of the mobile phone will naturally weaken a lot.
This is also Apple's careful thinking, after all, if every mobile phone is so silky and will not lag at all, how many people will keep buying new machines?
In addition to the health effect, when the battery level of the mobile phone is less than 20%, especially when it is less than 10%, no matter what brand of mobile phone will appear serious lag, and even open Douyin is difficult.
This is because when the battery is too low, the phone will force the power saving mode to start automatically, and the CPU and GPU frequency will be significantly reduced at this time.
The phone's sensors, push notifications, background processes, and so on, will also be automatically turned off.
If you've ever used a phone with less than 5% battery, I'm sure you've also encountered a situation where the camera won't turn on.
These are the self-protection measures of the mobile phone, which is to hope that the mobile phone can still last for a period of time under such a low power situation.
This kind of lag is a temporary situation, and when the phone is fully charged again, it will be full of energy again.
There is a great relationship between the feeling of use and the health of the battery, how to use the mobile phone correctly in daily life to ensure the health of the battery?
The most important point is not to think of charging until the phone has no power at all, and it is usually best to charge it at any time.
The battery is charged from 0~100% to a charging cycle, and each cycle is completed, which means that the service life of the battery is slightly shorter.
The standard charging cycle standard for Apple mobile phones is 500 times, which means that when the charging cycle reaches 500 times, the health of the battery can still be maintained at 80%.
If this happens during the warranty period, then this machine is definitely unqualified, and you can ask for a free battery replacement from Apple's official after-sales service.
If conditions permit, it is best to keep the battery power of the mobile phone in the range of about 25%~75% at all times, and when the battery of the mobile phone drops to about 25%, it is necessary to start thinking about charging, but it is best not to exceed 80%.
Although many mobile phones now have the function of fast charging, and the official claim that fast charging will not harm the health of the mobile phone battery, but from an objective point of view, slow charging is still more conducive to the health of the mobile phone battery.
Someone once experimented with a 5W, 18W, and 20W charger after buying a new iPhone. Two months later, the experimenters found that only the 5-watt Apple phone battery remained 100% healthy.
This can also show that fast charging will still slightly affect the life of some batteries.
Of course, our life is fast-paced, and it is impossible to think about charging the phone to 80% every day.
Then we can turn on the optimized battery charging function in the Apple phone, which will not affect your charging speed, but after the phone is charged to 80% of the power, the charging speed will be slowed down, so as to achieve the protection of battery health.
In addition, do not charge in an excessively hot or cold environment, and try not to charge while playing.
The lithium battery of Apple mobile phones has relatively high environmental requirements, and the official recommended operating temperature range is 16°C to 22°C.
The original charger is also used as much as possible when charging, and third-party chargers can also be used, but the quality and safety are difficult to guarantee. Some low-quality third-party chargers may also pose a risk of fire or short circuit.
