1. Do not charge until no power is turned off, so that it is charged with use
According to Apple's official statement, the core factor affecting the iPhone battery life is \"battery chemical age growth\
< br >
Apple's standard for this is: when the charging cycle reaches 500 times, the battery can maintain a maximum of 80% of the initial capacity, if within the warranty period, your iPhone battery health is lower than 80%, you can go to Apple's official after-sales application for free replacement of the battery.
< br >
It is worth mentioning that the standard given by Apple is extremely conservative, even if we reach 500 cycles of normal use, the battery health will not drop to 80% so quickly.
< br >
In this case, we want to delay the healthy decline of the iPhone battery, we should try to avoid charging and discharging to reach the cycle, that is, do not often use 0% to charge, usually when we have charging conditions, it is necessary to recharge at any time, the phone's power is best maintained in the range of 25% ~ 75, at least about 25% should consider charging.
< br >
2. Enable the optimized battery charging function
< br >
In Apple's official documents, there is a sentence that says: fast charge for convenience, slow charge for life.
< br >
Foreign institutions have done experiments, respectively, the use of 5w, 18w, 20w charger to charge the same new iPhone for two months, and finally found that only the use of 5w iphone battery to maintain 100%, often use fast charge is easier to shorten the battery life, the existence of trickle charging is still quite necessary. This is also the significance of optimizing the battery charging function.
< br >
The iPhone is the default to open the function of optimizing battery charging, if you do not care about the battery life of friends can choose to close, after closing, the iPhone charging speed will be improved, but the effect is not obvious.
< br >
This function will intelligently learn your charging habits, if you used to sleep at night when the mobile phone plugged in to charge overnight, it will remember this time interval, after 80% will slow down the charging speed, extend the charging time, which can greatly protect the battery health.
< br >
3. Do not charge in a hot or cold environment, and try to avoid charging while playing
< br >
The lithium battery performance of mobile phones and other electronic devices is fully operating at a temperature of 0~40 ° C, below 0 ° C lithium battery performance will decline, and above 35 ° C will lose battery capacity.
< br >
Apple officially mentioned that the best working environment for Apple devices is an ideal temperature band between 16°C and 22°C. In addition, Apple also stressed that when using the phone in a very cold environment, the phone's use time will be reduced and the battery will quickly drain, but this situation is only temporary. When the battery temperature returns to its normal operating range, its performance returns to normal.\"
< br >
That said, we should avoid leaving the iPhone in an environment where the temperature is higher than 35 degrees, and iPhoen may limit the charge after 80% of the battery is charged. If you charge your phone for a long time in a high temperature environment, it will cause irreparable damage to the battery.
< br >
In addition to environmental factors, the heat generated by the mobile phone itself will also affect the battery life, of which many people are used to charging while playing games is very easy to lead to abnormal heat of the mobile phone, so for the sake of battery health, we should try to avoid playing while charging.
< br >
Not only that, if the iPhone is wearing a protective case for wireless charging, it is also easy to generate too much heat, and we can remove the protective case when wireless charging to reduce the heat to a certain extent, thereby delaying the decline of battery health.
< br >
4. Try to use Apple's original charger when charging.
< br >
In the news, we can always see mobile phone charging fire accidents, and most of these are caused by the use of poor quality third-party chargers, poor quality third-party chargers lack the corresponding safety protection mechanism, it is very easy to have the risk of overcharging, overheating or short circuit.
< br >
Although Apple's original charger is not necessarily the fastest charging, but must be the safest, it has over-current protection, over-voltage protection, over-temperature protection, short circuit protection and shell flame retardant protection, under the premise of ensuring safety, but also to delay the decline of battery health to the greatest extent.
< br >
Apple's original charger is good, but it also has two problems that have been teased by many people for a long time, one is expensive and the other is not durable, its durability is mainly reflected in the material, the head of the charging line, especially in the hardest hit areas, so a considerable number of people will choose a third-party charger for this reason.
< br >
If you feel the same way in front of the screen, then I would recommend that you choose a third-party charger with Apple MFI certification, which has the same safety standards as the original charger, does not cause damage to the health of the iPhone battery, is affordable, and is made of more durable materials.
< br >
When the battery of my iPhone first fell, I was also very nervous, and almost every day I would check whether it would fall again, and then I found that the battery health of iPhone did not decline linearly, and it would decline after a period of time when it fell to 99% or 98%. When you have the illusion that it has been stable, Then it will suddenly drop 2, 3 percent in a row, and finally stay at 89 percent for a long time.
< br >
When the battery health is below 90%, my mentality has changed, perhaps because of \"old age\
IPhone Settings to save battery:
1, first open the Settings, then click on privacy, find location services.
2, and then click to close, positioning service is a service that consumes more power. Turning it off when we're not using it can significantly reduce our power consumption.
3, the phone back to the desktop, and then use the hand to swipe up, turn off the Bluetooth service. It can also be turned off from Settings. Turning off Bluetooth reduces battery consumption.
4, turn down the brightness, can also reduce the consumption of electricity.
5. Finally, tap Battery in Settings, and then tap Low Power mode. After opening, you can prevent the program from refreshing in the background to reduce power consumption.
There are many reasons why iPhone batteries drain fast, such as high brightness, multitasking, weak signal and so on. To slow down the battery consumption, you can do the following:
First, reduce the screen brightness, turn off the automatic lock screen and background refresh;
Second, turn off unnecessary applications and avoid multitasking.
Third, turn off unnecessary networking functions such as Wi-Fi and Bluetooth;
The fourth is to use low power mode. In addition, you can also consider updating to the latest system version to ensure that the system is optimized and possible power consumption issues are fixed.
First, replace the phone battery
< br >
The battery life of the iPhone will directly affect the card of the phone, if the battery life is not good, the phone will be more and more card. You can view the capacity of the cell phone battery in the cell phone battery. If it is lower than normal, replace the battery. This is also the fastest solution, but also to ensure the running speed of the mobile phone, when replacing must choose a professional and regular battery.

2. Turn off background app refresh
< br >
In fact, this is very important, in the general Settings, select background app refresh, and then close. This feature allows the iPhone to constantly refresh its old-school background when it connects to a wireless network or uses data. To some extent, it is very power-hungry, so turn this setting off early.
< br >
Third, find the application that is not suitable for the system
< br >
At the same time, you can look at the phone battery to see the most recent battery usage APP. If the APP is used normally, it is OK. If the APP has not been used much recently, but has been consuming the battery of the phone, it may be caused by the incompatibility between the mobile app and the system. Simply delete the app and download it again. My phone, for example, is constantly draining its battery, even when I am asleep. I just uninstalled and reinstalled wechat and solved it.
Some of the ways iphones drain power slowly are:
1. Turn off location information This must be turned off, find [Privacy] in [Settings], click [Location Services]
2. Turn off APP tracking rights to browse how various apps protect privacy, find [Privacy] in [Settings], and click [Tracking]. Disable Allow apps to request tracking permissions.
3. Disable iCloud Backup Tap the ID account in [Settings], select [iCloud], and disable [iCloud Cloud Backup].
4. Turn off background APP refresh Open [Settings], find [General], click [Background APP Refresh], and select Close. This setting must be turned off to prevent apps from using data privately and to improve the phone's battery life.
