If you’ve noticed your iPhone stop charging at 80%, don’t worry; it’s a common issue, and there’s a good reason behind it. Apple has built-in mechanisms to protect your battery’s lifespan, which can cause your device to pause charging before it reaches 100%. In this article, we’ll explain why this happens and guide you through the steps to fix it.
Why Does Your iPhone Stop Charging at 80%?
The primary reason your iPhone stops charging at 80% is optimized battery charging, a feature introduced in iOS 13. This feature is designed to extend your battery’s health by reducing the time your battery spends at a high charge level. Here’s why:
- Heat Management: Charging generates heat, and keeping a battery at high charge levels for extended periods can degrade its lifespan.
- Battery Chemistry: Lithium-ion batteries, like the one in your iPhone, age faster when held at 100% for too long.
When Optimized Battery Charging is enabled, your iPhone learns your charging routine. It pauses charging at 80% and waits to finish charging until just before you typically unplug it.
How to Fix Your iPhone Stopping at 80% Charging
If you need your iPhone to charge past 80%, you can disable optimized battery charging or address other potential issues. Follow these steps:
Disable Optimized Battery Charging
- Open the Settings app on your iPhone.
- Scroll down and select Battery.
- Tap Battery Health & Charging.
- Toggle off optimized battery charging.
Once disabled, your iPhone will charge past 80% without pausing. However, remember that this could slightly reduce your battery’s overall lifespan over time.
Check for High Temperatures
- iPhones stop charging temporarily if the battery overheats to protect it from damage.
- Ensure your phone is in a cool, ventilated space while charging.
- Avoid using thick cases that trap heat or charging under direct sunlight.
Update Your iOS
- Apple frequently releases updates to improve battery management.
- Go to Settings > General > Software Update and install the latest version of iOS.
Try a Different Charger or Cable
- A faulty charger or cable can disrupt the charging process.
- Use a certified Apple charger and Lightning cable, or a high-quality third-party accessory with MFi (Made for iPhone) certification.
Reset Your iPhone’s Settings
If the problem persists, resetting your iPhone’s settings might help:
- Navigate to Settings > General > Transfer or Reset iPhone > Reset.
- Select Reset All Settings.
- This won’t erase your data but will reset preferences, including Wi-Fi passwords and display settings.
Perform a Battery Health Check
- Go to Settings > Battery > Battery Health & Charging.
- Check the maximum capacity percentage. If it’s significantly below 80%, your battery may need replacement.
- Visit an Apple Store or authorized service provider for a battery diagnostic.
Additional Tips to Keep Your iPhone Battery Healthy
- Avoid extreme temperatures: Extreme cold or heat can damage your battery. Keep your iPhone within Apple’s recommended temperature range of 32°F to 95°F (0°C to 35°C).
- Charge Smartly: Try not to let your battery level drop below 20% frequently, and avoid keeping it at 100% for long periods.
- Use Optimized Battery Charging: It’s a handy feature for maintaining long-term battery health, especially if you follow a predictable charging schedule.
