According to the latest statistics, more than 60% of iPhone users experience significant battery performance degradation within two years of purchase. Are you one of them, often troubled by low battery anxiety? Whether your iPhone is low on power, slow to boot, or experiencing abnormal battery-related failures, it is important to understand the process of replacing your iPhone Battery. Let's explore some key considerations to help you complete the replacement process smoothly.
When to replace the battery?
If your iPhone charges slowly or often shuts down unexpectedly during use, this may be a sign of battery aging. According to Apple's recommendations, you should consider replacing the battery when the battery's time after reaching full capacity is significantly reduced or the maximum capacity drops below 80%.
How do you know if the battery is bad?
Battery health check: In iOS 11.3 and later, you can view the health of your battery through Settings > Battery > Battery Health. This feature will indicate the maximum capacity and performance capabilities of the battery. If it shows that the battery health has significantly decreased, it needs to be replaced.

Options for battery replacement:
Official service: It is strongly recommended to go to an Apple authorized service provider or Apple Store for battery replacement. Official channels use original authentic batteries to eliminate quality risks such as false battery life and overheating and bulging caused by non-original batteries, and can also avoid damage to the iPhone Motherboard and other components due to improper battery adaptation. It is worth mentioning that users with AppleCare+ service can directly enjoy free replacement service if the battery health drops below 80%, saving time and worry.
Self-replacement: Although there are DIY battery replacement tutorials and Battery Repair Tool Kits on the market, this method has high technical requirements. Precise operation is required during the disassembly process, and the slightest carelessness may damage precision components such as cables and screens. If you choose to replace it yourself, be sure to purchase safety-certified replacement batteries from regular channels, carefully check the compatibility of product parameters and equipment, and avoid risks such as Short Circuits and spontaneous combustion caused by battery quality problems.
Nearby mobile phone repair shops: Repair shops near your home often have the advantages of fast response and flexible prices, which are suitable for users who urgently need to solve battery problems and have limited budgets. However, the repair market is mixed. It is recommended to check the reputation and qualifications of the store in advance, actively ask whether it uses original or brand-certified batteries, and keep the repair certificate. If the device is abnormal after the repair, you can trace the after-sales guarantee with the certificate.

Before starting to replace the battery:
No matter which method you choose, be sure to back up all the data on your iPhone. Use iCloud or iTunes to fully back up your contacts, photos, messages, applications, and other important information. This protects your data in case of problems during the replacement process, such as accidental data loss due to improper operation or unforeseen technical problems.

When replacing the battery:
Pay attention to the quality of the battery. If you are not using an Apple-branded battery, make sure the third-party battery you choose is from a reputable manufacturer. Low-quality batteries not only have a shorter lifespan, but may also pose safety risks, such as overheating or battery swelling.

After replacing the battery:
Take some time to calibrate the new battery. Charge the battery to 100%, and then use your iPhone until it is completely discharged. Repeat this process several times to help the device accurately measure the battery capacity and optimize its performance.
