How To Check Battery Health On iPhone

Battery health is an important factor to consider when using an iPhone. Nobody wants to run out of battery in the middle of the day, and nobody wants a phone that dies quickly. In this guide, we will show you how to check your battery health and find out if there is anything wrong with it. We will also provide tips on how to improve your battery life.

How to check battery health on iPhone?

iPhones are known for their battery life, and for a good reason. Even with heavy use, most people can get a full day out of their iPhone without needing to recharge. However, over time, batteries naturally degrade and lose the ability to hold a charge as long as they did when they were new.

If you're concerned about the health of your iPhone's battery, there's a built-in tool that can give you some insight. Here's how to check battery health on your iPhone.

To check your iPhone's battery health, open the Settings app and tap Battery. On the Battery screen, you'll see two numbers: Maximum Capacity and Peak Performance Capacity.

Maximum Capacity is the total capacity of your iPhone's battery when it was new. As the battery ages, it will naturally lose some of its capacity.

Peak Performance Capacity is a measure of your battery's ability to deliver peak power. If your battery is unable to deliver peak power, you may experience unexpected shutdowns or performance issues.

If you want more detailed information about your battery's health, you can install a third-party app like coconutBattery. With coconutBattery, you can see not only your current maximum capacity and peak performance capacity but also your "Design Capacity."

Design Capacity is the total amount of power that your battery is designed to hold. As with Maximum Capacity, this number will decrease as your battery ages.

You can also use coconutBattery to see the "Cycle Count" of your battery. The Cycle Count is the number of times your battery has been completely discharged and then recharged. Every time you charge your iPhone to 100% that counts as one cycle.

Generally speaking, a battery is considered worn when it has a capacity of 80% or less. However, this number is not set in stone, and some people are comfortable with a lower capacity as long as their iPhone is still performing well.

If you're happy with the performance of your iPhone and don't mind the occasional recharge, then you don't need to worry about the health of your battery. However, if you're experiencing unexpected shutdowns or reduced performance, it's worth taking a closer look at your battery health.

How do I know if my iPhone battery is bad?

If your iPhone is older than two years, chances are its battery isn't going to be as good as it used to be. Apple's batteries are designed to retain up to 80% of their original capacity at 500 complete charge cycles, so if you're constantly topping up your phone throughout the day, you might start seeing some noticeable degradation in battery life.

There are a few telltale signs that your iPhone's battery might be on the way out:

  • Your phone doesn't hold a charge as long as it used to.
  • It takes longer to charge your phone than it used to.
  • Your phone feels warm to the touch when it's charging.
  • The battery percentage jumps up and down erratically.

If you're seeing any of these signs, it's probably time to start thinking about replacing your battery. You can either do it yourself (if you're feeling brave) or take it to an Apple Store and have them do it for you. Either way, it's not a bad idea to have a backup battery on hand, just in case.

How long do iPhone batteries last?

This is a question that gets asked a lot, and unfortunately, there isn't a clear answer. iPhone batteries are designed to retain up to 80% of their original capacity after 500 charges, but this number can vary depending on how you use your phone.

There are a few ways to check if your battery is holding less charge than it used to. One way is to go to the Settings app and navigate to battery> Battery Health. This page will show you your "maximum capacity," which is the measure of your battery's original capacity compared to its current capacity.

If your maximum capacity is below 80%, it means your battery isn't performing as well as it used to, and you might want to consider replacing it.

Another way to check your battery's health is to download a Battery Life app from the App Store. These apps will show you more detailed information about your battery usage and capacity.

If you're noticing that your battery isn't lasting as long as it used to, there are a few things you can do to help extend its life. One is to enable Low Power Mode, which will disable some features and background processes that use up a lot of battery power.

You can also try calibrating your battery, which you can do by charging it to 100% and then letting it drain all the way down to 0%. This can help improve your battery's accuracy in reporting its charge level.

If you're still having trouble with your battery after trying these things, then it might be time to get a new one. Replacing your battery is a pretty easy process, but it's important to make sure you get the right size battery for your iPhone model. You can find instructions for replacing your battery online or in the iPhone User Guide.

Once you have a new battery, be sure to take care of it, so it lasts as long as possible. Avoid exposing it to extreme temperatures, and don't let it drain all the way down to 0% too often. With proper care, your new battery should last you for a long time.

Is it OK to leave your iPhone charging all night?

Charging your iPhone overnight might be one of the worst things you can do to its battery. If your iPhone is plugged in, it's also working hard to maintain that charge. So if you leave it plugged in all night, that's just going to wear out your battery over time.

It is always ideal to unplug your iPhone as soon as it hits 100%. But if you must leave it plugged in, try to do so for only a short period of time.

In conclusion, checking your iPhone's battery health is important to ensure that your device is working properly. By following the steps above, you can easily check your battery's health and make sure that it is in good condition. If you find that your battery health is poor, then you should take action to improve it. There are a few different ways to do this, such as by reducing your screen brightness, disabling background app refresh, and more. By taking these steps, you can help to improve your battery health and keep your iPhone working properly for longer.
