iPhone Battery Health When To Replace

iPhones are amazing smartphones, but they aren’t particularly well-known for their battery life, are they? The iPhone 13 appears to have fixed this issue. All iPhone 13 models have bigger batteries than their predecessors, which means they last longer on a charge.

However, batteries are still consumable hardware with a finite lifespan. They will eventually degrade to the point that you will have no choice but to replace them. So, when will that be? Let’s see what happens! How do you tell when it’s time to replace your iPhone battery?

At what percentage of battery health should I replace my iPhone battery?

After 500 complete charge cycles, your iPhone should maintain up to 80% of its original battery capacity. When the battery health percentage falls below 80%, the quantity of charge your battery can retain begins to decrease. That doesn’t imply you should hurry out and get a new battery. That number is only for orienting purposes. This isn’t a one-size-fits-all situation.

For example, if you’re not viewing films or playing games, an iPhone with 70 or 80 percent battery health may still run for the entire day. It all depends on how you use the computer.

When you discover that your iPhone’s battery isn’t holding a sufficient charge to get you through the day, it’s time to replace it. In other words, if the amount your iPhone has isn’t enough for your needs or makes the device inoperable, you should change the battery.

Replace the battery when the battery life is bothering you enough to make you want to spend the money on a new battery. Most users should be OK with an 80 percent battery health level to get them through the day.

However, after 40 or 50 percent battery health, things start to go downhill quickly. After each charge, you will only be able to use your iPhone for a few hours. When your battery health falls below 40%, it’s time to replace it. Essentially, your iPhone becomes inoperable.

What Happens If Your iPhone’s Battery Health Is Low?

Battery degradation might potentially cause your iPhone to shut down abruptly. This is due to the battery’s inability to supply power to your physical components. Of course, if you want to avoid similar situations in the future, you should replace your battery as soon as it reaches 80 percent capacity.

Remember that low battery health concerns are more common on older iPhone models. Newer versions have better hardware and software architecture that works well when the battery isn’t as good as it should be.

The amount of apparent change is determined by how much strain you apply to your gadget. Other frequent symptoms of battery health concerns, aside from decreased battery life, include slow applications, poor frame rates, lower speaker volume, etc.

You are unable to halt the process.

As your iPhone’s battery ages chemically, you’ll get fewer hours of use between charges. As a result, you’ll have to charge your battery more regularly. There is, however, nothing you can do to halt this process. It’s just how lithium-ion batteries function.

While you cannot stop the process, you can delay it correctly by caring for your device. Here’s how to get the most out of your iPhone’s battery life and longevity.

How to Extend the Life of Your iPhone’s Battery

  • Keep your smartphone up-to-date to take advantage of the most recent battery-focused software enhancements.
  • Use your device only at moderate temperatures. If you must, don’t expose it to very hot or very cold temperatures for too long or too often.
  • While charging, remove the case. You remove the casing to keep the battery from overheating if you’re using the gadget in a hot climate.
  • Don’t charge your iPhone using third-party connections or chargers. Go all-in on Apple.


While your iPhone’s battery begins to degrade clearly after achieving 80 percent battery health, this does not necessarily indicate that you should replace it. If the smartphone still has enough charge to get you through the day, continue to use the same battery. Replace it if you notice significant performance concerns or if the device becomes inoperable.
