How to extend iPhone battery life?

Poor battery health is one of the most common reasons for deciding to buy a new iPhone model. If you have an iPhone 15 or newer (e.g. iPhone 16 or iPhone 16 Pro), then you can make daily use of a very useful feature in your phone's Settings called CHARGE LIMIT, which can easily help extend the battery life of your smartphone.

A characteristic of modern batteries is that they are most stressed when they are fully discharged or fully charged. The ideal state for a lithium-ion battery in terms of maintaining its lifespan is 50% charge, and as the iPhone approaches 100% charge, it is more stressed.

WHAT IS THE BATTERY CHARGING LIMIT?

Charging limit battery is an option available on iPhone 15 or newer models (such as the iPhone 16 and iPhone 16 Pro) that allows you to set the maximum battery charge from 80 to 100 percent in 5 percent increments. This reduces the chemical consumption of the iPhone's battery, resulting in a longer battery life.

Traditional charging to 100% puts more strain on the battery, especially when the smartphone is left connected to the charger for a long time (e.g. at night). Limiting charging to 80%, for example helps avoid so-called chemical stress, which can lead to a faster decline in battery capacity over the long term. This means that users who frequently charge their phones at night or use an iPhone connected to a charger for long periods of time can take advantage of this feature to reduce battery degradation and thus extend battery life.

The operation of lithium-ion batteries is based on charge and discharge cycles. Each full charging cycle (from 0% to 100%) affects the gradual reduction of their capacity. By limiting the level of charge, the battery does not go through full cycles as often, which has a positive effect on its long-term performance.

HOW IPHONE'S CHARGING LIMIT FEATURE WORKS?

The feature works automatically, stopping the iPhone's battery charging process when the so-called charging threshold is reached. If necessary, the user can manually resume charging to full capacity if deemed necessary (for example, before a long trip). Apple has used intelligent algorithms that learn the user's habits and can adjust the timing of charging resumption according to the user's daily routine. When the function Charge limit is active, the iPhone does not allow the battery to reach 100%, which reduces the number of full charging cycles and slows down its degradation process.

Studies show that lithium-ion batteries, used in Apple iPhones, wear out more slowly when not regularly charged to maximum capacity. This means that use of this function can increase the time, in which the battery will maintain its optimal performance. In addition, thanks to iOS integration, the user can monitor the battery charge status in real time and decide whether to fully recharge if necessary.

HOW TO ENABLE CHARGING LIMIT ON IPHONE?

To start using the charging limit function, follow these steps:

1. Hole Settings on your iPhone.

2. Go to section Battery.

3. Select the option Charging.

4. Set the charging threshold from 80 to 100 percent.

If you have set the limit to 80 percent, then from then on your iPhone will limit the battery charge to 80 percent, taking care of its better condition in a longer period of daily use of the phone.

WHETHER IT'S WORTH USING THE CHARGING LIMIT?

Using this feature is especially recommended for people who:

• Most often, they charge the iPhone at night or use it when it is connected to a charger - such as a charger MagSpot,
• They want to keep the battery capacity high for as long as possible,
• They change the iPhone every few years and care about its longevity.

However, if you travel frequently or need maximum battery capacity on a daily basis, you can disable this feature to use 100% capacity.

SUMMARY

Function Charging limit is a great solution for people who want to extend the battery life of their iPhone. By intelligently limiting charging to 80%, you can reduce battery degradation and enjoy better battery health for a longer period of time. Enabling this feature is simple and worth considering if you want optimal performance from your device for many years to come.

The final decision to use this feature depends on the individual needs of the user. If your priority is battery longevity, it is worth leaving it active. However, in situations where a full charge to 100% is necessary, the charging limit can be temporarily turned off. With this flexibility, users can customize the way they charge their iPhone to fit their lifestyles, while taking care of battery health in the long run.
