How To Check Battery Health On IPhone 


Just like it is on any other device, the iPhone battery will slowly degrade the more often it is charged,  and used. That’s how they were made. However, your iPhone’s battery is guaranteed to last forever or to function at its best.

The good news in this scenario is that Apple has a function that allows you to check the health of your iPhone’s battery and adjust how the device charges to ensure that you get the longest possible battery life from your device.

TIn addition to the regular built-in battery health check and a few other iPhone features that aid in battery management, there are some things you can do to ensure your battery lasts are several things that you can do to ensure your battery lasts longer and the inbuilt battery health check and some other features also help you out. This article will discuss how you can check battery health on iPhone and also maintain the health of your iPhone battery.

What does iPhone battery health mean? 

The Battery Health page shows your iPhone’s remaining battery capacity, among other breakdowns of battery health.

Following Apple’s description, the Maximum Capacity listed is “a measure of battery capacity relative to when it was new. A new device would come in at 100% battery capacity. With time, such battery capacity reduces. Lower capacity may result in fewer hours of usage between charges.” The closer your device is to 100%, the better.

Apple says your phone’s battery is “designed to retain up to 80% of its original capacity after 500 complete charge cycles,” which for most people takes about two years. 

How do I check battery health on iPhone?

Below are the simple steps to check battery health on iPhone along with other iPhone battery settings you should know about

Step 1. Launch the Settings app on your iPhone.

Step 2. Scroll down and click on the Battery.

Battery Capacity

Here, you will find out your battery’s Maximum Capacity. This tells you how much of the battery’s original capacity remains, which in turn tells you how much your battery has declined. The closer it is to 100%, the better. 80% and above is widely considered good regarding the iPhone’s maximum battery capacity. For example, let’s say your Maximum Capacity is 80%; this means that a full charge now will last you as long as a new battery charged to 80% would.

You would see two other options when checking battery health:

  • Peak Performance Capability

This indicates whether your iPhone is being slowed down to avoid an unexpected shutdown. When the battery is degraded,  your iPhone’s processing power is limited by iOS. However, you can bypass that and restore the original iPhone speed, but the issue here is that your iPhone’s battery won’t last as long and might shut down unexpectedly. 

  • Optimized Battery Charging

This relates to your charging habits and how your device adapts accordingly. If you charge your iPhone every night and unplug it at 6 AM, your iPhone battery won’t be fully charged until 6 AM or thereabout. This happens because keeping your iPhone on the charger while its battery is full contributes to its degradation. 

How to maximize the battery performance  of your iPhone

“Battery life” is the time a device runs before it needs to be re-charged. “Battery lifespan” is the time a battery lasts until it needs to be replaced. Let’s find out how you can maximize the lifespan and performance of your device’s battery. 

1. Update to the latest software

Simple yet effective. Apple software updates often include advanced energy-saving technologies, so always make sure your device is using the latest version of iOS.

2. Avoid exposing your device to extreme  temperatures

The ideal temperature comfort zone is between 16 – 22 degrees). Avoid exposing your device to an ambient temperature higher than 35 degrees. For example, under direct sun, near a high-heat area, etc. The damage can be irreversible and decrease the battery’s long lifespan. 

3. Store it half-charged when you store it long term

If you are not using your device for a while: you can adopt some of the following steps:

  • Do not fully charge or discharge your device’s battery – charge it to around 50%. 
  • Switch off the device to avoid additional battery use. 
  • Place your device in a cool, moisture-free environment of fewer than 32 degrees. 

4. Optimize your settings 

You can optimize some of your settings which will, in turn, help preserve your device’s battery life. Some of the settings you can optimize include:

  • Adjust your screen brightness. Dim the screen or turn on Auto-Brightness to extend battery life
  • Disable Bluetooth connection if you are not using wireless speakers. 
  • Set Auto-Lock to 1 Minute. Setting your iPhone to standby mode when not used can help conserve your battery life. 

5. Enable Low Power Mode

Low Power Mode is an easy way to extend the battery life of your iPhone when it starts to get low. It allows you to use important apps till your phone is charged again. 

6. View Battery Usage Information 

To view your usage, go to Settings > Battery. This allows you to see the app that takes up most of your battery life and change the settings to minimize battery usage.  

7. Disable Features You Don’t Use

There are probably some features you never use but are using up power in the background. You can consider disabling these battery-draining features:


So, it’s no news that the maximum battery capacity of your iPhone battery can’t stay at 100% forever, and you can use the steps discussed in the article to check battery health on iPhone. With time, this level is bound to drop. However, as shown in the article above, you can ensure you maintain the battery capacity, and you, in turn, enjoy your device’s battery life. 

Frequently Asked Questions 

How exactly does your iPhone complete charge cycles?

Apple uses a lithium-ion battery which employs fast charging to reach 80 percent of its capacity quickly, then switches to slower trickle charging. An iPhone lithium-ion battery typically holds up to 500 charge cycles, or about two years, before you see a degradation of the battery to 80% of its full capacity. 

You complete one charge cycle when you have used an amount that equals 100% of your battery’s capacity. For instance, you use up 60% today and re-charge it the next day. If you use 40% the next day, you will have discharged 100%. That is one charge cycle. It could also take several days to complete a cycle. 

When should you replace your iPhone battery? 

When the capacity of your iPhone battery dips below 80%, you’ll most definitely get a message saying: “Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity. More about service options….”

This doesn’t mean you still can’t make use of that battery but just simply letting you know it won’t be at the level it once was since the maximum battery capacity has dropped. You might be unable to effectively carry out some tasks, such as playing games, as this would require more battery usage. 

Can you leave your iPhone to charge overnight, even at 100 Percent?

Well, theoretically speaking, you can.  Once the battery is complete, the iPhone will automatically discharge some of its charges so it can continue receiving a charge without damaging the battery. However, in the long run, this might, later on, have adverse effects on the battery cycle of your device.
