How To Tell If You Should Replace iPhone Battery

Are you using an iPhone for a while and wondering if you should replace your iPhone battery? Don’t worry! We’ll clear your perplexion on this matter. Before replacing your iPhone’s battery, you should check for some signs. To learn more about these signs, you can read this article.

Many iPhone users face failing battery issues because, according to a 2022 survey, at least one-third of iPhone users buy previously owned iPhones that don’t have 100% battery capacity.  You can easily differentiate between a new and a used battery by looking at the hours of usage between charges. 

People often rush to buy a new one. But it can be a waste of money because sometimes replacing the phone’s battery can improve its performance like new. You can simply go to the Apple store; they will replace the battery for free if you still have the warranty time left. And if the phone is out of warranty, you can replace it for a specific price.

Signs to Replace iPhone Batteries

These are the signs that indicate that it’s time to replace your battery:

1. Battery Health Decreasement

The maximum capacity of an iPhone’s battery is 100%, and you’ll find this maximum capacity in your new phone. But if you buy an active iPhone, the capacity may be less than 100%. Also, if you buy a phone that is activated long after manufacturing, the capacity may show less than 100%. 

According to what Apple claims, their phone’s batteries can maintain normal conditions when they are up to 80% of their original capacity. So when it goes under 80%, you may experience some inconvenience while using the iPhone. But if it goes below 70%, it can become a real headache, and that’s when you should replace the battery.

2. Swollen or Bloated Battery

If your phone’s battery gets swollen or bloated, you should replace the battery immediately. If you don’t replace it in time, the battery may cause the phone to malfunction, leading to catching fire. 

3. Unexpected Shut Downs

The primary sign of a failing battery is unexpected shutdowns. If your iPhone shuts down randomly, it means the battery cannot supply enough power to keep the phone running. When this lack of power supply occurs, it takes longer for the apps to launch, restarts take longer, and the screen keeps stuttering or hangs when scrolling. 

4. Sluggish Performance

If you have a damaged battery, your iPhone will function slowly, and it will take a long time to run apps even though you’re not using many apps. A failing battery makes the processor slow, causing the phone to run out of power than usual.

5. Battery Percentage Barely Lasts a Few Years

A damaged battery, or battery with low capacity, drains the iPhone’s battery quicker than usual. It doesn’t hold charges for more than a few hours. In short, the battery loses the capability to hold the charge, causing the phone to run out of power.

In case you are already using iMazing or similar tools, you may view the actual capacity of your iPhone battery. It may help to understand about the condition better.

How much does it cost to replace an iPhone battery?

Battery replacement for previous models like the iPhone X, iPhone 11, iPhone 12, and iPhone 13 was $69. But now the scenario has changed, and it costs $89 for iPhone’s battery replacement. However, in the case of the iPhone 15 or 14 series, the price is relatively high from the beginning, which is $99.

If you want to replace the battery of older models of iPhones like the iPhone SE, iPhone 8, and earlier models, you can do it cheaper than the newer ones. Even though it’s cheaper than new models, their battery price has risen to $49 from $69.

To be the cherry on top of this increased price, Apple has stated that the out-of-warranty battery service fee will get a $20 increase will apply to all iPhone models before iPhone 14 and 15. 

Is it Worth it To Replace a Battery in an iPhone?

Many people have the misconception that if an iPhone’s battery capacity is below 80%, they have to replace the battery. But that’s not true, and if you do it based on only the battery capacity, it won’t be worth your money. 

But you should replace the battery if your phone shows other signs along with low battery capacity, including a bloated battery or random freezing issue. After replacement, your iPhone will be as smooth as new. So, it will be worth the money as you don’t have to waste money to buy a new phone.

Of course, spending $69 on a battery is better than spending over $1000 on a new iPhone when they will give an almost close performance! 


We hope that we cleared your perplexion on whether you should replace your iPhone battery by mentioning the clear signs above in this article. 

Replacement of the battery depends on the battery capacity and the ability to hold charges. Apart from these signs, damaged bloated batteries should be replaced too.  So when you see any of the mentioned signs happening to your iPhone, replace it as soon as possible.
