iPhone batteries deteriorate over time even with normal use. Of course, various features have been added to iOS to make the battery last as long as possible, but did you know that the latest features have been added to the iPhone 15? It is a “charge limiter” function that limits the battery charge to 80%. You can prevent battery deterioration by not charging to 100%, so please try using it.
What is the new “charge limiter” function installed in the iPhone 15 series?
Not only iPhones but also smartphone batteries deteriorate rapidly even with regular use. In particular, the more times you charge a battery, the sooner it will reach the end of its life.
One of the causes of a battery deteriorating quickly is if the battery is used up to 0% and left unused. Another example is charging the battery at night before going to bed and continuing to charge it even after it reaches 100%. If you have any concerns, please be careful.
In this way, if you continue to use the battery roughly, it will deteriorate faster, and the battery’s maximum capacity will eventually drop to less than 80%.
The iPhone battery is designed to reach a maximum capacity of 80% after 500 full charge cycles, so if it drops below 80%, the battery won’t last a full day. Probably.
Steps to check the maximum capacity of your battery
Select “Battery Status” under “Battery” in the iPhone settings (photo on the left). If “Maximum Capacity” is “80%” or less, the battery has reached the end of its lifespan.
Did you know that the iPhone 15 has a new feature that allows you to set the battery charging limit to 80%? This is what is called a “charge limiter.”
If you set this function, charging will stop when the battery charge reaches 80%, so you can prevent battery deterioration more than usual.
The setting method is simple: open “Settings” on your iPhone, select “Battery” → “Battery Health and Charging” and select “Charging Optimization”. It is OK if you check “Upper limit 80%” here.
If you want to extend the battery life of your iPhone even a little, check the settings now.

Steps to set the charging limit to 80%
First, open your iPhone’s settings and select “Battery” (photo on the left). Next, tap “Optimize charging” on the “Battery health and charging” screen (pictured on the right)
If you check “Up to 80%” in Charging Optimization, the battery will only be charged to a maximum of 80%.
How to prevent battery deterioration on iPhone 15 and earlier models?
If you use the iPhone 15’s charge limiter, the battery will not be charged unnecessarily and will last longer, but is there nothing you can do with older models?
In fact, Apple has added several features in the past to help prevent device battery deterioration.
For example, iPhone 13 and later include a feature called “Battery Charging Optimization,” which delays charging once the battery reaches 80%.
To enable this feature, open “Battery” from iPhone settings, and turn on “Battery Charging Optimization” under “Battery Health & Charging.”
Steps to turn on “Battery Charging Optimization”
From iPhone settings, go to “Battery” → “Battery Health & Charging” (pictured on the left) and turn on the switch for “Optimize battery charging” (pictured on the right).
There are other ways to extend your iPhone’s battery life. First of all, what you should keep in mind is not to charge the battery to 100% and not to let it run down to 0%.
It is said that you can extend the life of your battery by charging and discharging between 20% and 80%, preferably by charging 50% and discharging (using) 50%.
The golden rule is to never charge your iPhone to 100% or use it to 0%. If possible, charge and discharge (use) the battery between 20 and 80% (the photo is a screenshot taken by the author)
Also, you need to pay attention to the temperature of the battery. In fact, the iPhone is designed to perform best when the temperature is between 16°C and 22°C.
Therefore, in extremely hot places (above 35 degrees Celsius) or cold places (below 0 degrees Celsius), not only will the battery not be able to achieve its original performance, but the battery will also be damaged.
If you won’t be using your iPhone for a long time, charge the battery to 50% and store it in a cool place with a temperature below 32 degrees Celsius.
iPhone batteries perform best at temperatures between 16°C and 22°C. It can be used in locations above 35 degrees Celsius and below 0 degrees Celsius, but please do not charge it (the photo is for illustrative purposes only).
summary
What do you think? This time, we introduced the new “Charging Limiter” function that can be used with the iPhone 15 series.
By setting the charging limit to 80%, you can extend the life of your battery, so it’s a good idea to do so.
Also, if you have an iPhone 13 or later, you can use the “Battery Charging Optimization” feature, so be sure to turn it on.
If you want to use your iPhone for as long as possible, make sure to actively use these features to extend the battery life as much as possible.
