If the used (discharged) power reaches 100% of the battery capacity, it means that your iPhone battery has completed a charging cycle, but it may not be completed in one charge.
For example, you may use 75% of the electricity in a day and then fully charge your iPhone at night. The next day, you used 25% of electricity, so the total discharge reached 100%, and a charging cycle was completed in two days. It may take several days to complete a charging cycle. Therefore, it is not necessary to discharge 100% before charging.
After a certain amount of charge, the capacity of any type of battery will decrease. The capacity of lithium-ion battery will be slightly less with the completion of each charging cycle. After 500 charging cycles, the lithium-ion battery of iPhone can maintain at least 80% of its original battery capacity.
The charging process of the lithium-ion battery of this iPhone is related. The lithium battery of iPhone adopts fast charging method, which quickly reaches 80% of the power, and then switches to slow trickle charging. Depending on the settings and charging equipment, the time required to fully charge the initial 80% charge will be different. When the battery abnormally exceeds the recommended temperature, the software will limit charging after the battery reaches 80%.
Fast charging is convenient, and slow charging ensures battery life. This combination process allows you to take the equipment out of the room more quickly, while extending the battery life.
The official didn't explicitly say that you can't use batteries when the power is less than 80%. If the battery exceeds the warranty, you don't have to spend money in your pocket, and some batteries are replaced by non-original certified batteries. The system can't detect the health of the battery at all.
It's always a problem for iPhone users to decide when to change the battery, unless the battery is obviously inflated. Otherwise, it is difficult to judge from the appearance where the life of the mobile phone battery has gone.
In fact, generally speaking, the life of iPhone battery will gradually age in one year to one and a half years. The aging phenomenon is as follows:
1, fast charge and discharge
Fast charging consumes fast power, or slow charging consumes fast power.
2. The battery will jump.
Originally, the battery may only have 20% power, but when it is connected to a charger, it suddenly becomes 30% or even 40%.
3. Turn off the power supply
It is clear that there is still at least 1~20% power, but it will turn off by itself. When the charger is plugged in, it will show that there is still electricity.
In the case of pure standby, the mobile phone can't be used for a day.
If this happens to your iPhone, it's basically an aging battery, so you need to consider replacing it with a new one. In fact, if you look closely at the after-sales terms, you will find that Apple officially suggests that if the battery capacity is lower than 80%, you need to replace the new battery.
The original battery contains a proprietary chip. As long as the mobile phone system detects that the chip data battery has obvious aging phenomenon, it will slow down the system speed to maintain the complete energy efficiency of the mobile phone.
The battery that is replaced without permission will not show the health information of the battery in the battery health. After this function is activated, once the user replaces the battery at a non-Apple-designated maintenance point, whether the original battery is replaced or not, the system will display "Unable to verify whether this iPhone uses the original battery of Apple. This battery has no health information. " And the user will be forbidden to view the battery health information in the system.
The reason why Apple did this is actually the result of a combination of factors:
1, the natural event of Samsung's mobile phone almost brought disaster to Samsung. The battery has become the focus of all mobile phone manufacturers, and no one dares to make mistakes in this matter. Replace the battery, check any link from the process specification, and eliminate the hidden danger of the battery, even if it will be vomited by many users.
2. Apple's APP ecosystem and hardware ecosystem never want to be touched by any third party. Adding a microcontroller to the battery and adding an MFi authentication chip to the data line are all such examples. Because once the hardware is damaged, the first thing users complain about is "Apple products have problems", not the failure caused by third-party accessories. On the other hand, many third-party batteries not only have better parameters but also better performance than the original ones, but Apple has already seen the business opportunities.
The mobile phone should be charged at 1 day 1 ~ 2 times, and it is better to replace the battery about 1 year to 1 year and a half.
Mobile phone 1 day needs to be charged more than 3~5 times, and 1 year may need to replace the battery.
The mobile phone battery itself is a consumable. If the battery performance is really bad, you should consider replacing the battery as soon as possible. After all, the mobile phone carries our daily life and work, and we can't let it affect our efficiency and mood. When replacing the battery, it is recommended to replace the original battery through normal after-sales channels. Not only to ensure the performance of mobile phones, but also for the safety of mobile phones.
Apple's mobile phone battery capacity is only 82%. I strongly recommend replacing the battery.
It is undeniable that Apple's official standard is that battery health is less than 80% before it is recommended to change batteries. In fact, when the battery health is still around 85%, the battery life is already very poor. The author's iPhone 8 Plus, when newly bought, went out at 8 am and came back at 8 pm, with a power of about 35%. When the battery health drops to 85%, it should be recharged twice.
The battery health of the Apple mobile phone is still 82%, and the battery life will definitely shrink. Therefore, it is recommended to replace the battery. After all, it is quite troublesome to charge it twice a day.
If the main mobile phone has exceeded the warranty period, it is recommended to replace the third-party battery, and it is not recommended to replace the original Apple battery. In terms of price, Apple's original battery is too expensive and its battery capacity is small. The third-party brand large-capacity battery replaced by the author has been used for more than half a year, and its battery life is OK.
Now mobile phone battery technology is very mature and the price is relatively transparent. Replace the battery of a third-party brand and choose a regular store. For example, Pinsheng, Scud, Fujishima, these batteries have a good reputation. If you can't replace the battery, it is recommended to find a mobile phone repair shop to replace it. The cost is around 30 yuan.
In short, whether Apple's mobile phone needs to be replaced depends not only on the health of the battery, but also on whether the battery life is seriously reduced. What's more, Apple officials also said that the battery health is only a reference figure.
Hello, I suggest that you can replace the battery now. If conditions permit, you can choose Apple to replace the original battery. Or you can buy your own battery to replace it. I have had the experience of changing my own battery, and I can watch the online video tutorial several times. As long as I am careful, it is not complicated. For the first time, the Scud battery was replaced, and there was a serious bulging phenomenon within three or four months. After the sale, it was replaced, but it was not installed. I bought Pinsheng battery again. I have used it for one year now, and there is no problem. Pinsheng battery is installed on the door! More convenient.
Apple's battery capacity is generally significantly smaller than that of Android phones, especially in previous generations. Battery capacity is a big shortcoming of Apple's mobile phone. For heavy users, it is difficult to ensure that the new mobile phone is charged once a day.
The battery efficiency of 83% indicates that the mobile phone battery is almost in need of replacement. If you don't replace the battery, it will affect the experience first. It is very unpleasant to charge twice or more times a day and take a data cable or charging treasure with you when you go out! There should be many friends who feel the same way! Secondly, the battery efficiency is reduced, the use of mobile phones will be stuck, and Apple mobile phones will automatically reduce the frequency.
Pay attention to protect the battery when using the mobile phone at ordinary times. 1. Try to avoid continuing to use the mobile phone when the power is low, the power should not be less than 20%, and charge it in time. 2. Avoid playing mobile phone while charging. Playing mobile phone while charging not only damages the battery, but also has certain security risks, especially playing games while charging.
My current fee is 82 pounds ... [shaking hands], but since I have a pd fast charge and the car is carplay, I think it is acceptable to charge at any time ... It is more convenient for my company to put a wireless charging board, and I want to stick to below 80.
Ok, answer the topic of this industry, I hope my answer will help you!
What are the current shortcomings of Apple's mobile phone? One is weak signal, and the other is small battery capacity. This is really not nonsense. You can compare the mainstream Android flagship with the current iPhone and you can see it at a glance!
Then the problem is coming. The battery capacity of the landlord's Apple mobile phone has reached 82%. I think this has reached the critical point of battery replacement.
The reason why I proposed a new battery is mainly because of the use of the machine. Because now each of us is a heavy user of mobile phones, even if you don't play games, do you have to brush videos and news? Originally, the power of Apple's mobile phone didn't last long. As a result, the battery capacity dropped again. If you don't consider changing the battery, it is definitely not ideal to use your mobile phone every day!
Ensure that the power of the mobile phone is not less than 30%, that is, you can charge the mobile phone when the power is 30%, and try not to make the battery display turn red or yellow.
Now some friends still like to pay more for fast charging. In fact, fast charging is harmful to the battery. Never touch the wireless charging, the wireless power is unstable! Minimize high current discharge scenes, such as playing games for a long time and watching videos for a long time. Everyone needs a rest, let alone a cell phone.
Conclusion: I don't know how long the landlord's iPhone has been used, but in terms of power, it is obviously possible to replace the battery. If you don't want to change it, you might as well buy a new mobile phone, provided your purse is full!
The Iphone has always been relatively valuable, but in the context of the upcoming popularity of 5g, the shortcomings of the iphone have become increasingly prominent!
Iphone has three major shortcomings, poor battery life, weak signal and no support for 5g.
The reason why the battery life of iphone is not ideal is obvious, that is, the battery capacity of iphone is much lower than that of Android flagship machine, so the battery attenuation of iphone battery is fatal to its battery life. When the battery decay reaches 82%, it has reached a very critical level, and your iphone may soon have a "urine collapse"! At this time, many people's thoughts will be to replace the battery as soon as possible, and I think we should sell the iphone in the second-hand market as soon as possible and replace it with a 5g mobile phone. Especially in the case that the iphone signal problem is quite serious in the past two years, it should be replaced as soon as possible!
All existing iphones do not support the 5g function, which has become the fatal shortcoming of the iPhone in the 5g era. Now the 5g network has not been fully covered, so the fatal injury of the iphone has not yet appeared. Iphone is still relatively valuable, and there is still demand in the second-hand market. This is also the last chance to sell the iphone. If China completes the coverage of 5g network next year and iphone 12 will be released soon, then it is not just the battery that "urinates" the existing iphone.
By then, the iphone that does not support 5g will plummet, and no one cares!
Glad to answer your question!
For mobile phone lithium battery, due to the chemical characteristics of lithium battery, it will age with the repeated charging and discharging of mobile phone, leading to the increase of internal resistance and the decrease of mobile phone capacity.
There is a charging and discharging standard for mobile phone lithium batteries, that is, after a fresh lithium battery has completed 600 complete charging and discharging cycles, the available capacity cannot be less than 80% of the rated capacity of the lithium battery. If we charge and discharge the mobile phone once a day and a half on average, the number of battery cycles for almost three years is calculated as follows:
(365/ 1.5)*3=730 times, which means 730 charge and discharge cycles in three years.
There is an empirical formula to calculate the capacity change of mobile phone lithium battery during aging, that is, the capacity of lithium battery will decrease by about 3% after 100 charge and discharge cycles. According to the above estimation, the remaining capacity after 730 charge and discharge cycles in three years is as follows:
1-3%*(730/ 100)=79. 1%。
In other words, if the mobile phone is charged once a day and a half, when the battery capacity of the mobile phone becomes 80%, it is equivalent to using the mobile phone for about three years.
Apple mobile phone, the general service life is 4 to 5 years, after three years of use, the endurance is obviously weak; For Android phones, there will be a certain degree of congestion and performance degradation in about 2 years. At this time, it is recommended to replace the battery to ensure the comprehensive experience effect of the mobile phone.
For lithium batteries, the best service life is generally 3~5 years. After more than three years, the aging of lithium batteries will be more intense, resulting in a lot of capacity decline, affecting the overall battery life experience of mobile phones. At this time, it is strongly recommended that you replace the original battery with a new one.
The above views are for reference only, welcome to pay attention to communication!
It is recommended to go to the official after-sales replacement if it is within the warranty period. If the battery efficiency is lower than 80, it can be replaced for free after sale.

The health status of your mobile phone battery is still in a healthy state. If the battery health is lower than 80%, as long as it can be charged and discharged normally, as long as it does not affect the use, you can choose to continue using it. If it affects the experience, you can choose or find a professional repair shop to replace the battery. I would like to remind you that you must choose original batteries or reliable batteries, and if you use an iPhone7 or above, you need to do professional protection after replacing the batteries, otherwise it will affect the waterproof effect of the mobile phone. Buy a fast charge or paper clip battery. At present, domestic mobile phone manufacturers have introduced fast charging technology and many fast charging heads. For example, Xiaomi's fast charging head supports charging the iPhone, which can alleviate the troubles caused by poor endurance. In addition, the clip-on battery is also a good choice. Although the mobile phone is heavy, its endurance can be significantly improved.
