Checking the health of your iPhone battery is critical because it allows you to determine whether the internal battery needs to be replaced. Poor battery health means that you will get fewer hours of use out of your iPhone before it needs to be charged. If you’ve had your iPhone for a while, you’ve probably noticed that the battery doesn’t last as long as it used to. This is perfectly normal. Your battery’s quality will deteriorate over time.

Checking Battery Status on Your iPhone

Before beginning with the steps you need to follow to check your iOS version. Make sure your iPhone running on iOS 11.3 or higher.

  1. Open Setting app on your iPhone.
  2. Scroll down and tap Battery.
  3. Tap Battery Health.How to Check iPhone's Battery Health

You’ll see your battery’s remaining capacity, among other things. It is a comparison of your current battery capacity to when it was new. When you bought your iPhone, the battery capacity was set to 100%. This percentage decreases over time, which is completely normal for lithium-ion batteries. The lower the percentage, the fewer hours of use you’ll have between charge cycles.

According to Apple, an iPhone’s battery retains approximately 80% of its capacity after 500 charge cycles or approximately two years.

When to Replace an iPhone’s Battery

You can monitor your iPhone’s battery performance using the Peak Performance Capability option. The iPhone will display various messages based on which you can determine whether the battery needs to be replaced.

  1. Go to Settings > Battery.
  2. Tap on Battery Health.
  3. You will see what the Maximum Capacity of your battery is – this is a measure of your battery capacity relative to when the battery was new. The older your iPhone, the lower this number is likely to be. Apple advises that “Lower capacity may result in fewer hours of usage between charges.”
  4. Below is an indication of the battery’s Peak Performance Capacity.

You can check here to see if your battery is working properly. Among the messages you may encounter are:

  • “Your battery is currently supporting normal peak performance” – If your battery has no failures and is performing as it should; you’ll see this message.
  • “Built-in dynamic software and hardware will help counter-performance impacts that may be noticed as your iPhone battery chemically ages” – If you’ve had your iPhone for a while, you may have noticed this message. It indicates that your phone’s battery has begun to degrade.
  • “This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again” – This message indicates that you are having battery problems. You’ll notice that your phone has slowed down in addition to the message.
  •  “Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity” – This message will appear on the screen if your iPhone’s battery capacity is less than 80%. You can continue to use the same battery, but your phone will be much slower, and it is recommended that the battery be replaced.

The last two messages indicate that you should replace your battery to ensure that your iPhone’s performance is not jeopardized.

Other factors to consider when determining whether your battery needs to be replaced include:

  • If your phone restarts and the message appears “This iPhone has experienced an unexpected shutdown.” Performance management options will be enabled in this case to prevent this from happening in the future. You can choose to disable it, but remember that you won’t be able to re-enable it. If there is another shutdown, the option will be enabled automatically. In this case, you should think about replacing the battery.
  • If you have a newer iPhone and notice it has slowed down, is overheating, or is unable to open certain apps, you may need to replace the battery or take it to an Apple store to be fixed up.
How to Maximize Battery Life On an iPhone

If you want to ensure that your battery lasts as long as possible until it can be replaced, try the following suggestions:

  • Turn off Location Services.
  • Disable Background App Refresh.
  • Make sure Auto-Brightness is enabled.
  • Use Airplane Mode when you don’t need to be connected to the internet.

If you’re desperate for more battery life from your iPhone, you should think about getting a Smart Battery case. These cases protect your phone in the same way that a regular case does, but they also charge your phone when you need it.

Apple notes that the number of times a battery has been charged is “not the only factor in this chemical aging process”, because “device use” and “leaving or charging a battery in a hot environment” can cause a battery to age faster.

Those lot of explanations are important to remember. Make sure you comprehend your iPhone’s Battery Health and do the tips to maximize your battery life on. Good luck!
