How To Maintain The Battery Of Apple Mobile Phone? Learn This Trick And Keep Fighting For Another Two Years With 80% Health
A large number of Apple users have a common problem, that is, after using the mobile phone for more than two years, the battery health dropped below 80%, the battery life dropped off a cliff, and charging two or three times a day became the norm.
If you want to go to the official store to replace the battery, it will cost hundreds of dollars. If you choose a third party to replace it, you will worry about the quality being not guaranteed. It will be very confusing and very disturbing.
In fact, after the iOS system was updated in 2026, Apple officially launched a number of new features for battery protection. Without spending any money, by adjusting several settings, it can delay the aging of the battery, thereby improving battery life, so that mobile phones with battery health below 80% can continue to be used smoothly for another two years.
These methods are all officially certified, tested, and effective. Today, I will explain the detailed steps and real results thoroughly. All of them are in easy-to-understand terms. Just follow them.
Check the health of the battery first, and have a good idea
Even if the battery health does not exceed the 80% bottom line, it cannot be judged that the mobile phone has been scrapped. It is just that the battery has officially entered the aging stage, and battery life and performance will be affected accordingly.
When the health level is above 90%, the status is normal, and the battery life is not much different from that of new phones; when it is between 85% and 89%, there is slight attenuation, and there is no problem in daily use, but the power consumption is a little faster than before; if it is lower than 80%, the system will trigger performance management, and occasional lags will occur, and the battery life will be greatly reduced.
Many people rush to replace the battery when they see the battery is below 80%, but in fact there is no need to do so.
Battery aging is irreversible. However, with the help of scientific settings, the aging speed can be slowed down, thereby reducing the occurrence of wear and tear. At the same time, the daily battery life can be improved; it can fully meet the needs of normal use within two years.
There are several settings, which are battery protection functions that Apple officially promotes. The time limit is 2026. These settings will be adapted on all models. Their operations are simple and simple. If used for a long time, they can reduce the annual degradation of battery health by 5% to 8%. The effect of this reduction is equivalent to allowing the battery to support more than a year.
Turn on optimized battery charging, the most important step
This is a very important battery protection function of Apple. Although it is turned on by default, many people will accidentally turn it off after upgrading the system, so be sure to confirm that it is turned on.
The system will use the machine to learn your charging habits. For example, if you are used to charging at 11 o'clock in the evening and unplug the charging cable at 7 a.m., in this case, it will first charge the battery to 80% and then suspend the operation. When it is almost time to unplug the charging cable, it will replenish the remaining 20% of the battery.
Doing this can avoid and prevent the battery from being in the high-voltage state of 100% full charge for a long time, thereby greatly reducing the loss.
For iPhone 14 and earlier models, you need to do the following: first open settings, then find battery options, then enter battery health and charging, and finally turn on the "optimize battery charging" function.
For iPhone 15 and newer models, do the following, find the Settings option, then enter the battery section, click Charge, and then turn on the feature called "Optimize Battery Charging."
A little reminder, after turning it on, it will take 7 to 14 days to learn your charging habits. Keep the charging time as fixed as possible, so the effect will be better.
Customized charging limit, exclusive benefits for new models

In 2026, after the iOS update is completed, iPhone 15 and subsequent models will add a "charging upper limit" function, which can accurately control the amount of charging to balance battery life and battery life.
The actual situation is that when the battery is fully charged for a long time (100%), it will accelerate its aging. So setting the charging limit to 90% can not only meet the purpose of normal battery life on weekdays, but also achieve the effect of reducing the degree of aging under high voltage. After actual testing, it was found that compared with full charging, the health level can be retained in the range of 5% to 8% per year.
The setting method is, Settings, then enter the battery option, then find charging, and then find the charging limit. For normal use, select 90%. It can be adjusted in 5% steps. You can temporarily adjust it to 100% before a long trip.
Furthermore, in 2026, the iOS26 system will add the "adaptive power" function. You do not need to manually turn on low power mode, but the system will automatically save power for you.
Based on your usage habits, it automatically adjusts the performance of the phone, such as lowering the screen brightness, limiting background activities, and automatically turning on the low-power mode when the battery is at a low level. There will be no lag during daily use, and the battery life can be increased by about 25%.

Setting path: Settings → Battery → Power Mode → Turn on “Adaptive Power”.

Turn off the three culprits of power theft, and the battery life will be increased by half
After the battery ages, the battery life is already poor, and some useless functions secretly consume power, making the experience even worse.
These three settings are high power consumption items that are clearly stated and recognized by Apple officials in the 2026 stage. When they are turned off, the battery life of old models will generally increase by 50%. After actual testing, the effect is effective.
App refresh in the background is all enabled by default. Even if you do not open the App, it will still quietly perform network operations in the background and refresh data, which in turn will consume more than 10% of the battery in a night.
It is recommended to close or keep only commonly used apps.
The setting path is, go to General Settings, find Background App Refresh in General, and select Turn off or Wi-Fi only for Background App Refresh.
Positioning services can be said to be one of the extremely power-consuming functions in the iPhone. Many apps do not require positioning at all, but are in the "always allowed" state by default, continuously calling GPS and thus consuming power, and also leaking privacy.

It is recommended to change it to "While using" or "Never".
Setting path: Settings → Privacy and Security → Location Services → Adjust app by app.
Turn off automatic updates. For mobile phones, by default, they will perform system updates and App updates on their own. This will not only consume power, but also consume data, and also occupy performance. As a result, the phone will become hot when it is placed in your pocket, and the battery will drain faster.
Path setting: First perform the setting operation, then find the App Store option, and then turn off "App Update" and "Automatic Download".
Avoid three battery-damaging behaviors and develop good habits
Daily usage habits, in addition to settings, are also very critical. Many people have inadvertent behaviors that are causing the battery to age faster. You must avoid these three minefields.
First, do not carry out deep discharge, try not to use the power below 20%, let alone use it in the shutdown state.
It can be charged when the battery is lower than 30%. It is the best habit to charge as you use it.
Secondly, do not charge in high-temperature environments: In the summer, do not leave your phone in the car to be exposed to the sun, and do not play games or watch videos while charging, because high temperatures will cause the battery to age twice as fast as before.
Third, don’t leave it fully charged all night: Many people often charge it before going to bed at night. The charging period extends to a whole night, causing the battery to remain in a fully charged state for a long time with the battery reaching 100%. This will accelerate its aging.
After turning on "Optimize Battery Charging", this problem can be perfectly solved.
Actual testing shows that the battery capacity is 78% and there will be no problem for another two years.
There are many such friends around me. The battery health status of the iPhone 12 and iPhone 13 they hold is within the range of 75% to 80%. After setting it up according to the method mentioned above, the effect is particularly remarkable.
There was once a user of iPhone 12 whose battery health level was 78%. Before that, he needed to charge his phone three times a day. After watching short videos for an hour, the phone's battery would drop by 40%.
After adjusting the settings, charging once a day is enough for normal use. If you watch short videos for an hour, your electronic battery will drop by about 20%. The battery life has doubled directly, and after more than a year of use, the health has only dropped by 3%. It is still in a state that can be used smoothly.
When the health of the battery is less than 80%, there is no need to rush to replace it. First adjust these settings, and then develop good usage habits. In this way, there is no problem at all for another two years, which can not only save money but also make you feel at ease.
The phone is a device we cannot live without. Proper maintenance can reduce unnecessary expenses.
For mobile phones, those shared today are the latest battery maintenance techniques in 2026, which are very common and can be easily operated by ordinary people. After reading this, we should quickly set up and try them out to say goodbye to battery life anxiety and let old mobile phones glow with new vitality.
