How Long Does An iPhone Battery Last?

Are you curious about the actual battery life of an iPhone? You are in the proper location!

How well you take care of your iPhone battery will determine how long it lasts, ensuring that you won’t be unprepared without a phone when you need it most.

The majority of people believe that a phone has a two-year lifespan because this corresponds to an average of two years of use for most users. With proper care, you can get between three and five years from iPhones, possibly even longer.

In this article, we’ll respond to some frequently asked questions about iPhone batteries, covering everything from knowing what good capacity levels are and what you can do to extend iPhone’s battery life.

Your iPhone’s original battery has a very, very long lifespan. People I know who own iPhones that are more than five years old and STILL have their original batteries.

That these iPhones no longer last 12 to 20 hours on a single charge is the major caveat in this situation. Only six to eight hours may be possible on an iPhone with a five-year-old battery before it needs to be recharged.

Apple isn’t to blame for this. The maker of the iPhones, Apple, is required to abide by the laws of chemistry and psychics even though it is one of the most technologically advanced businesses on the planet.

The lithium-ion battery, which is used in Apple’s iPhones, is the newest stable battery technology, but lithium-ion batteries still rely on chemical processes that deteriorate over time.

These lithium-ion batteries have a lower capacity to hold full charges as they age and degrade. Because of this, the battery life of an iPhone (and any other computing device, including Android phones) gradually decreases. The battery technology we rely on has a natural accusing process where a battery can no longer hold a charge for as long.

So how long does an iPhone battery actually last? Here by “actually” we mean, how long can you expect an iPhone’s battery to be capable of retaining a “like-new” charge? That answer also depends on just how aggressively you use and charge your iPhone, but for all practical purposes, an iPhone battery will have “like new” charge capabilities for about two years.

The battery life of your iPhone will start to decline after two years (as per physical laws, not a sinister Apple plot). Past this two-year mark, your iPhone battery will be by no means “dead” but it just won’t hold as much of a charge as it used to.

The majority of iPhone users, however, probably won’t need to consider replacing their iPhone battery until it has been used for four years. And by then, purchasing a new iPhone just makes sense.

What iPhone Battery Capacity is Considered An Optimal Condition?

You might believe that the only situation that qualifies as ideal is when your iPhone’s maximum capacity is at 100%. That isn’t exactly accurate, though. Any iPhone that has a battery capacity of 80% or higher is deemed to be in excellent condition by Apple.

Apple cares so much about battery health, in fact, that its one-year warranty will cover any battery with 80% or more capacity. iPhones with battery capacities of 95% or higher after a year are not uncommon to see.

Because Apple builds its batteries with excess capacity, even when the Battery Health indicator reads 100%, it doesn’t actually use all of its available operating power. Your phone is still working at peak efficiency even when it is at 80%.

How to Check the Battery Status of Your iPhone?

How Long Does An iPhone Battery Last?

Go to Settings > Battery > Battery Health on any iPhone running iOS 11.3 or later to see how much juice is left in the battery. It’s important to remember that this feature is only accessible on iPhone 6 and later models.

Peak Performance Capability is a significant secondary metric that you can see on your Battery Health screen. This screen might actually be more significant than capacity due to the aforementioned nuance.

A straightforward message stating that your phone is performing at normal peak levels will be displayed if your battery is operating optimally to support all of your installed apps. You will notice a warning that your battery has degraded and needs to be replaced if it is worn out and potentially in need of replacement.

Your phone will still work if you see the warning message, but there will be much less time in between charge cycles. Only when your battery capacity is 79% or lower does the message appear.

How to Maximize iPhone Battery Performance?

Through performance throttling, also known as performance management, which generated some controversy a few years ago, Apple has attempted to increase the battery life of their phones.

To keep the iPhone running and preserve battery life, performance management slows down your phone’s performance on your behalf. You can manually turn it off, but doing so will cause your iPhone’s battery to quickly deplete because the device will be working at or near its limits.

Instead, it makes sense to take these few simple steps that can extend your phone’s battery life, courtesy of Apple:

  • Maintain the most recent iOS upgrade. New features that preserve and increase battery life are included with every significant upgrade.
  • The ideal temperature range for your phone should be between 16 and 22 degrees Celsius. Any amount above or beyond could harm your lithium battery.
  • When charging, keep the temperature down. Your phone’s battery may suffer damage if it overheats due to certain cases or surfaces. While it is charging, make sure it stays cool by checking it.
  • Store your phone with only a partial charge. The battery could enter a deep discharge state after being completely discharged, which would result in serious harm. The same outcome might result from a full battery’s drainage.
  • On the auto-brightness setting. The brightest screen settings have a tendency to quickly deplete your battery, forcing you to charge it more frequently and causing battery deterioration.
  • Settings > General > Background Refresh is where you can check your background activity. Your battery will be drained if there are too many background apps running.

How Long Do iPhones Last?

Much longer than the battery, if you’re wondering how long an iPhone lasts. An iPhone 4 will soon turn almost ten years old, but I know people who are still using them. Naturally, their old iPhone no longer receives iOS updates, but it still functions.

iPhones usually are still perfectly capable smartphones for at least 5-6 years after you buy one. However, they may last a decade or longer. If you do not want to upgrade to a new iPhone, you will most likely need to get an iPhone battery replacement once you have exceeded the 4-year mark because your iPhone battery will begin to suffer significantly.


An iPhone battery can last for at least two years because it can hold a full charge for between 500 and 800 battery cycles, or full charges before capacity drops to about 80%.

In general, the iPhone typically prevails in battery comparisons. It’s strong from the beginning and keeps being strong for a longer period of time. That is why anyone looking for a refurbished smartphone should consider it.


How Often Does An iPhone Battery Need to Be Replaced?

Your iPhone’s battery has a finite shelf life no matter what you do. A full charge won’t last as long as it once did because the battery slows down with age. Most batteries are good for at least 2 to 3 years, often longer, but how do you know when to replace your iPhone battery? Asurion helps millions of people make the most of their technology.

How Do I Know If My iPhone Battery Needs to Be Replaced?

iOS 11.3 and later for iPhone 6 and later add new features to display battery health and suggest battery replacement if necessary. You can find these in Settings > Battery > Battery Health (with iOS 16.1 or later, find in Battery Health & Charging under Settings > Battery.
