iPhone 11 Pro Max Battery Health: Understanding the 87% Conundrum


The iPhone 11 Pro Max is a powerful device that boasts an impressive battery life. However, some users have reported a peculiar issue where their device's battery health drops to 87% despite proper care and maintenance. In this article, we'll delve into the reasons behind this phenomenon and provide guidance on how to address it.

What is Battery Health?

Before we dive into the 87% mystery, let's first understand what battery health means. Battery health refers to the capacity of a lithium-ion battery to hold its charge relative to its original capacity. A battery's health is gauged by its ability to supply power to the device, and it's measured in percentage terms.

Why Does Battery Health Drop to 87%?

There are several reasons why your iPhone 11 Pro Max's battery health might drop to 87%. Here are some possible explanations:

Normal Wear and Tear

As you use your iPhone, the battery will naturally degrade over time. This is a normal process, and it's expected that battery health will decrease gradually.

Charge Cycles

A charge cycle is when you charge your iPhone from 0% to 100%. The more charge cycles, the more the battery health will degrade. Apple estimates that an iPhone 11 Pro Max battery will retain up to 80% of its original capacity at 500 charge cycles.

Environmental Factors

Extreme temperatures, humidity, and physical damage can also affect battery health. If you live in an area with high temperatures or humidity, it may impact your battery's performance.

Manufacturing Defects

In some cases, a manufacturing defect could be the reason behind the 87% battery health. If you suspect that your iPhone 11 Pro Max has a faulty battery, you may need to contact Apple Support for assistance.

What to Do if Your iPhone 11 Pro Max Battery Health Drops to 87%?

If your iPhone 11 Pro Max battery health has dropped to 87%, here are some steps you can take:

Update Your iPhone

Make sure your iPhone is running the latest software. Sometimes, software updates can resolve battery-related issues.

Calibrate Your Battery

Calibrating your battery can help improve its performance. To calibrate your battery, let it drain to 0% and then charge it to 100%. Repeat this process a few times to see if it makes a difference.

Avoid Extreme Temperatures

Keep your iPhone away from extreme temperatures, which can affect battery performance.

Contact Apple Support

If none of the above steps resolve the issue, you may need to contact Apple Support for further assistance. They can help diagnose the problem and provide a solution or replacement if necessary.


In conclusion, a 87% battery health on an iPhone 11 Pro Max is not uncommon and can be attributed to various factors. By understanding the reasons behind this issue and taking proactive steps, you can help extend the life of your iPhone's battery. If the problem persists, don't hesitate to reach out to Apple Support for assistance.
