All rechargeable batteries are consumable components, and their performance and capacity will gradually decrease over time.
Have you noticed that your phone is losing power faster and faster? Or did it suddenly shut down one day? These phenomena may be your iPhone sending you a "battery distress signal".
Today we will talk about: 6 danger signs that you must replace the battery, and how to choose a reliable battery replacement solution to avoid expensive repairs or data loss.
6 Warning Signs Your Battery Must Be Replaced
Understanding your battery's health and replacing it when necessary is an important step in maintaining optimal performance of your iPhone. Here are six signs that may indicate you need to replace your battery:
Battery health is less than 80%
You can check the maximum capacity by going to Settings > Battery > Battery Health & Charging. If the battery health is less than 80%, the system may have enabled Peak Performance Management to prevent unexpected shutdowns. In this case, it is recommended to replace the battery to restore full performance.
Battery life is significantly reduced after charging
If your device's battery drains significantly faster under normal use or can't last a full day of daily use, this is often a sign of battery aging. The new iPhone battery can give you all-day battery life, helping you focus on everything that matters.
Unexpected shutdown of the phone
When the battery cannot provide the maximum power required instantly, the iPhone may automatically shut down to protect the internal components. This type of problem is more common in devices with aging or declining battery performance, and can be solved by replacing the battery.
iPhone Slow Performance
To prevent shutdowns caused by aging batteries, iOS may throttle system performance. This may cause apps to open more slowly, scroll less smoothly, or have an overall slower experience than before. After replacing the battery, the system will return to normal performance.
The phone is heating up abnormally during charging or use
Battery aging not only affects performance but can also cause the device to heat up during normal use. Although the iPhone has a strict thermal management mechanism, we recommend that you go to an Apple Authorized Service Provider for testing if heating occurs frequently.
Battery swelling or bulging of the device casing
This is a rare but serious sign that the battery is physically damaged. Stop using the device immediately and take it to an Apple Authorized Repair Center for safe disposal.
How do I safely replace my iPhone battery?
Apple's official replacement prices are high, so many users prefer to look for cost-effective and reliable third-party battery replacements.
