When your iPhone reaches 80% battery life, you might notice that the charging speed slows down. There are several reasons why this occurs. In this article, we will explore the reasons behind this phenomenon and what you can do about it. πŸ”

Battery Management at its Best:

One of the main reasons for this is battery management. iOS, the operating system of the iPhone, has a feature called "Battery Health" that manages the charging and discharging of the battery to extend its lifespan. When the battery reaches 80% capacity, the charging speed slows down to prevent overcharging and damage to the battery. πŸ”‹πŸ’‘

Temperature Matters Too:

Another reason is temperature. Charging an iPhone when it is very hot can damage the battery, so iOS throttles the charging speed to keep the temperature under control. If your iPhone is very hot when charging, try to cool it down before continuing to charge. β˜€οΈπŸ”₯

Faster Charging Options:

If you want to increase the charging speed past 80%, you can try using a different power adapter or cable. Some third-party adapters and cables may provide faster charging speeds than the ones provided by Apple. However, be careful to ensure that they are safe and compatible with your iPhone. πŸ”Œβš‘

Wrapping Up:

In conclusion, the reason why the iPhone charging speed decreases when it reaches 80% is to protect the battery and manage its lifespan. By following these tips, you can ensure that your battery stays healthy and your iPhone charges as quickly and safely as possible. πŸ”ŒπŸ”‹πŸ’‘

Β Step-by-Step Solutions to Fix the Charging Limit

  1. Disable Optimized Battery Charging:

    • Go to Settings > Battery > Battery Health.
    • Turn off the β€œOptimized Battery Charging” option.
    • This should allow your phone to charge beyond 80%.
  2. Check Your Charging Environment:

    • Ensure your iPhone is not in a hot environment, as heat can trigger the 80% charging limit.
    • Move your phone to a cooler spot and try charging again.
  3. Inspect Your Charging Accessories:

    • Faulty cables or adapters can hinder charging. Try using a different charger or cable to see if the issue persists.
    • Always use Apple-certified charging accessories for the best results.
  4. Update Your iOS:

    • Sometimes, a software bug can cause charging issues. Updating to the latest iOS version can resolve these bugs.
    • Go to Settings > General > Software Update to check for updates.
  5. Hard Reset Your iPhone:

    • A hard reset can help fix temporary glitches.
    • The method varies depending on the iPhone model, but generally involves pressing and holding specific buttons until the Apple logo appears.
  6. Battery Health Check:

    • If your iPhone's battery health is significantly degraded, it may not charge fully.
    • Go to Settings > Battery > Battery Health to check your battery's condition.
    • Consider replacing the battery if its health is below optimal levels.
  7. Seek Professional Help:

    • If none of the above solutions work, it might be time to consult an Apple technician.


An iPhone only charging to 80% can be a minor hiccup in your daily usage, but with these straightforward solutions, you should be able to tackle the problem effectively. Remember, maintaining your iPhone’s battery health is key to ensuring a long-lasting device.
