How to judge whether the iphone battery needs to be replaced?

If your iphone frequently experiences inaccurate battery levels, shortened battery life, and unexpected shutdowns, it may be due to an aged or damaged battery which requires replacement. This article will teach you how to test the health of your iphone's battery and how to obtain official battery replacement services.

Testing Battery Health

iphones come with a battery health report system which displays the maximum capacity and peak performance capacity of the battery. Maximum capacity refers to the maximum amount of electrical charge the battery can store, expressed as a percentage compared to a new battery. Peak performance capacity refers to the maximum instantaneous power the battery can provide, which affects the phone's operational speed and stability. If these two indicators fall below 80%, it indicates that the battery has degraded and may require replacement.

To view the battery health report, you need to go to "Settings" > "Battery" > "Battery Health and Charging". Here, you can see the battery's maximum capacity percentage and peak performance capacity status. If you receive the message "Battery needs servicing" or "Recalibration unsuccessful", it indicates that your battery has issues and needs to be replaced as soon as possible.

In addition to the built-in functionality, you can also use third-party software to obtain detailed information about your Apple phone's battery. For example, you can download apps such as "Battery Life" or "iTools" from the App Store, which can display the battery's actual capacity, cycle count, temperature, impedance, and other data. This data enables you to more accurately determine if your battery is working correctly.

Obtaining Official Battery Replacement Services

If you are certain that your iphone needs a battery replacement, the best option is to obtain official battery replacement services. This ensures that you receive an original, high-quality battery and benefit from quality assurance and after-sales service. You can obtain official battery replacement services in the following ways:

Book an appointment at an Apple Store or authorized service provider. You can search for nearby service points on the Apple Support website and make an online appointment. Once you arrive, the personnel will inspect your phone and advise you if a battery replacement is necessary and the cost involved. Generally, a battery replacement takes between 15 and 30 minutes.

Contact an Apple support technical advisor. You can select "Contact Us" on the Apple Support website, then choose "iPhone" > "Battery, Power, and Charging" > "Phone Support". The technical advisor will communicate with you and assist in arranging mail-in repair services or an appointment at a service point.

Use the Apple Support app. You can download the "Apple Support" app from the App Store and select "iPhone" > "Battery, Power, and Charging" > "Battery needs servicing" > "View all", then choose either onsite or mail-in repair.

Regarding the official battery replacement service fees, they may vary for different models of iPhones. Currently, in mainland China, the cost for models of iPhone X and above is RMB 519, and RMB 359 for models of iPhone 8 Plus and below. If you have an AppleCare+ service plan and the battery defects cause the battery storage capacity to fall below 80%, you can get a free battery replacement. If your iPhone has other damages, such as a cracked screen, you may need to resolve the relevant issue before replacing the battery, which may result in additional repair costs.

The above provides several methods for determining if an iphone battery requires replacement and if necessary, how to obtain official replacement services. In addition to official channels, you may also choose to replace your battery with a third-party iphone replacement battery which provides ultra-high capacity, extended standby and battery life, as well as one-year warranty service to ensure after-sales service.
