Whatever you do, your iPhone® battery has a finite lifespan. The battery slows down as it ages, so a full charge won’t last as long. Most batteries last at least two to three years, and often much longer, but how do you know when to replace your iPhone battery?
iPhones are powered by rechargeable lithium-ion batteries. They charge quickly and fit more power into a smaller battery than ever before. Older iPhones are more vulnerable to battery problems than newer models, which are designed with advanced features that compensate for poor battery health. However, all batteries deteriorate over time.
If your phone keeps shutting down unexpectedly and you can’t get through a day on a single charge, you most likely have a battery problem. Sluggish apps and lower-than-usual speaker volume are also indicators.
Make sure your phone is fully charged before going to Settings > Battery and selecting Battery Health. You’ll find information on maximum capacity, performance capability, important battery messages, and when to replace your iPhone battery here.
Let’s take a closer look at what you could discover.
This is where you’ll find a clear indication of whether your battery needs to be replaced. This percentage compares the battery capacity of your phone to when it was brand new. It starts at 100% (or slightly less), and as the battery ages, capacity decreases, resulting in fewer hours between charges. According to Apple, if the number under Maximum Capacity is greater than 80%, you have a healthy battery.
When your battery has the maximum capacity available and is operating normally, you’ll see the following message in your Battery Health screen:
“At the moment, your battery is supporting normal peak performance.”
If your battery is causing slower load times or other performance issues, it’s time to replace it. You will see the following message in this case:
“This iPhone shut down unexpectedly because the battery was unable to deliver the required peak power.” To help prevent this from happening again, performance management has been implemented.”
If you’re looking for a unique way to communicate your message, this is the place to be.
“This iPhone shut down unexpectedly because the battery was unable to deliver the required peak power.” You have disabled performance management safeguards manually.”
Remember that once you’ve turned off performance management, you can’t turn it back on. If your phone shuts down unexpectedly, it will automatically restart. You can also choose to disable it.
When the capacity of your iPhone battery falls below 80%, the following message appears:
“The health of your battery has significantly deteriorated. To restore full performance and capacity, an Apple Authorized Service Provider can replace the battery. More on service options…”
Don’t be concerned. This does not imply that your battery is faulty; rather, it holds less charge than it
did when it was new. If you only use your phone for email and social media, the battery may be adequate. However, if you’re a gamer or power user, you should probably replace the battery.
When your phone is unable to determine the health of the battery, possibly due to an unknown or improperly installed battery, you will see the following message:
“This iPhone cannot determine battery health.” The battery can be serviced by an Apple Authorized Service Provider.”
If you have an iPhone XS, XS Max, XR, or later, the following message indicates that your battery cannot be verified:
“We were unable to confirm that this iPhone has a genuine Apple battery.” This battery does not have any health information. Find out more…”
If you receive this message, it’s time to schedule an appointment with an iPhone repair specialist. They can inspect your battery and advise you on the next steps.
