How to Keep iPhone Battery Health at 100: A Comprehensive Guide


iPhone battery is an essential factor in the use of an iPhone. In today’s world, where smartphones run our lives, maintaining optimal battery health is crucial. A healthy battery ensures that we can stay connected, entertained, and productive throughout the day without any interruptions. This article is a comprehensive guide on how to keep your iPhone battery health at 100% for as long as possible.

Understanding Battery Health

Battery health is the capacity of a battery to hold and maintain its charge level over an extended period. It represents the state of your battery’s overall performance. iPhone batteries can up to a certain extent work without any concerns, but as time goes, the performance dips down gradually.

The majority of iPhone users confront the effect of battery degradation, which refers to the reduction in battery capacity over time. Batteries tend to degrade over time due to various reasons that are unavoidable. In this section, we will examine the causes of battery depletion.

There are specific factors that cause battery health degradation. One of the main reasons is heat. High temperatures are a significant contributor to reducing battery health. Charging a battery too quickly or storing an iPhone in a hot place may cause battery damage. The second factor is age, which is inevitable. It has often been noticed that batteries will start to age after one year of regular use. The third factor is how the battery is used. Fast charging and excessive use of applications might put a burden on the battery, causing it to degrade in the long run.

Maintaining Optimal Charging Habits

Keeping the iPhone charged for an extended period is not necessarily the right approach. In this section of the article, we will go through optimal charging habits that will prolong your iPhone’s battery lifespan.

The first thing to consider is how the iPhone should be charged. It is recommended to charge the battery before it falls below 20%. Don’t let your battery level go to zero since it can cause irreversible damage.

The second thing to keep in mind is where we should charge the iPhone. Avoid charging the iPhone if it exceeds a particular temperature. Charging near windows or heaters can cause the iPhone to heat up and harm the battery. It is essential to charge your phone in a cool place.

The third thing to consider is how long you should charge your iPhone. Overnight charging is not recommended. It’s ideal for charging the iPhone from 20% to 80%. It would be best if you avoided overcharging of the battery as it can damage the battery longevity.

Battery Life-Extending Hacks

In this section, we will explore some tips and tricks to extend the lifespan of an iPhone battery.

iOS includes an inbuilt feature to extend the life of the iPhone battery, known as Low Power Mode. Enabling Low Power Mode by going to Settings -> Battery -> Low Power Mode will deactivate some of the iPhone’s advanced features, such as iCloud sync and automatic downloads, to save on battery power.

Reducing screen brightness is a simple way to save on energy and extend the battery life. To reduce screen brightness, go to Settings -> Display & Brightness -> Brightness, and adjust the brightness to your liking.

Background app refresh is another feature that can harm battery life. Apps running in the background continue to use power, even when not in use. To prevent this, go to Settings -> General -> Background App Refresh, and turn off the feature for apps that you don’t frequently use.

Optimal Usage Patterns

In this section, we will discuss some optimal usage patterns to follow to preserve battery life.

Though it might be tempting, avoid playing games or watching videos online for long periods. These activities require significant energy consumption, and as a result, they put a strain on the battery lifespan.

You should also avoid overusing apps. Excessive use of applications puts enormous stress on the battery, and it is a common reason why batteries degrade quicker than usual.

Turning off location services for unnecessary applications will also help prolong battery life.

Maintenance and Replacing the Battery

Even after taking necessary precautions, there may come a time when it becomes inevitable to replace your iPhone’s battery.

It is advisable to maintain battery health through long-term methods. Apple provides an official battery replacement program that allows you to replace the battery at a reasonable price.

If you are handy with a screwdriver, you can try replacing an iPhone’s battery. However, it is not a simple task and should only be attempted by experienced individuals.


This article was a comprehensive guide on how to keep iPhone battery health at 100% for as long as possible. We explored different aspects of battery health, optimal charging habits, life-extending hacks, optimal usage patterns, and maintenance and replacing the battery. Taking necessary measures to maintain battery health can help ensure your iPhone performs optimally throughout the day, and prolongs battery life.

To summarize, we hope that our tips in this guide will help you keep your iPhone’s battery health at 100%. Remember, maintaining battery health is essential for better performance, and it’s possible through proper usage of charging habits and following optimal usage patterns.
