Some iPhone users reported that their phones stopped charging at 80%, especially after updating the iOS 16.4.1. This can be frustrating, especially when you need to charge the iPhone fully. This phenomenon is mostly related to iPhone battery management features, which are designed to optimize battery health but can sometimes confuse users. Understanding its reasons can ensure better iPhone performance.
In this article, you will learn about the common causes behind this issue, the effective solutions to fix it, and tips to increase the battery lifespan!
Why Does My Battery Stop Charging at 80%?
There are several reasons why an iPhone may stop charging at 80%. Here are some leading ones to consider:
Charging Optimization
Apple introduced the “Optimized Battery Charging” feature in iOS 13 to prolong battery lifespan. This feature uses machine learning to study users’ charging habits, preventing the battery from charging beyond 80%. It helps reduce wear on the battery caused by keeping it at full charge. However, this can sometimes misfire, especially if your routine changes or you need a full charge at unexpected times.
Overheating of iPhone
iPhones are designed with thermal management systems to prevent overheating during charging. If the device becomes too warm, the iPhone won’t charge past 80 as a protective measure. This prevents further heat generation, which can degrade battery performance over time.
Hardware Damage
If the battery or charging components are damaged, your iPhone won’t charge past 80. This can be the wear and tear of internal battery components, water damage, or issues with the charging port. If there is hardware damage, the charging capacity might be affected, requiring a professional repair.
Efficient Approaches to Avoid iPhone Stop Charging at 80%
After exploring the causes behind your iPhone not charging past 80, there are several approaches you can take to avoid this problem:
Cool Down Your iPhone
If the iPhone is overheating, allow it to cool down before resuming charging. Moving to a cooler environment or reducing the usage of heavy apps while charging can prevent thermal issues from disturbing the charging process.
Take off iPhone Case
A protective case can trap heat, contributing to overheating issues during charging. Removing the case while charging helps to dissipate heat more effectively and can prevent the phone from stopping its charge at 80%.
Use Original or MFi-certified Charger and Cable
Using non-certified charging accessories can affect the charging process and may lead to inefficiencies. To maintain proper charging functionality, use an original Apple or MFi (Made for iPhone) certified charger and cable.
Keep the Battery over 20%
Dropping your battery below 20% frequently can stress it, causing it to degrade faster. Maintaining a charge above 20% when possible can help avoid issues with the phone’s charging system, including the 80% limit.

Tips: How to Maximize Your iPhone Battery Lifespan
Although the iPhone likely lasts 3 to 4 years, the battery is degradable and sometimes gets consumed significantly with time. So, let’s explore some key tips to ensure your iPhone battery lasts long and functions efficiently:
Keep Away from Extreme Temperatures
Firstly, you should stop exposing your iPhone to extreme cold or heat, as these conditions can degrade the battery over time.
Avoid Fully Charging and Completely Discharging
Charging your iPhone between 20% and 80% is ideal for battery health. Avoid regularly fully charging or letting the battery drain to 0%.
Use Wired Charging
Wired charging is generally more efficient and less prone to overheating than wireless charging, helping maintain battery health over the long term.
Use Fast Charger Only When Needed
While fast charging is convenient, using it frequently can harm the battery. So, use fast chargers only when necessary, and stick to regular charging otherwise.
