If you are using a refurbished iPhone and the message "Important battery message" suddenly appears, it can be confusing at first. Don't worry, this message has no impact on the performance of your device. We'll explain what's behind it.
Why does the iPhone display this message?
Starting with the iPhone XS, Apple has built in a function that indicates whether the battery has been replaced with a spare part that does not come directly from Apple. This is because the battery is permanently connected to the circuit board from these models onwards. If the replacement is not carried out by Apple itself, the device does not recognize the new battery as "original" - even if it is a certified quality product.
Apple says that this message is for user safety. At the same time, however, there is speculation that it is also intended to make independent repairs and refurbishments more difficult. However, the message has no negative consequences for you.
What does the message mean for your iPhone?
The "Important Battery Message" message simply means that your iPhone cannot verify the built-in battery. The message disappears after a few days and has no effect on the functionality or performance of your device. The only limitation: information about the battery status (such as the maximum capacity) is not displayed in the settings.
Why replacing the battery still makes sense
Refurbished devices undergo strict quality checks before they go on sale. If the original battery of a device no longer offers sufficient capacity, it is replaced with a certified new battery. These batteries meet the highest standards and offer you a user experience that is just as reliable as the original.
Especially with older iPhone models, a battery replacement is often the most sensible option to continue using the device. Replacing a battery directly at Apple can quickly become more expensive than the current value of the device itself. Professional workshops, other specialists and our technical team at Janado therefore rely on certified batteries that are just as safe and powerful - but significantly cheaper. This means your iPhone will remain a loyal companion even after many years.
Third-party batteries are functionally identical to the original Apple parts, but are not recognized as such due to a special chip that only Apple or authorized companies can program. The quality remains unaffected.
This is what the battery replacement means for you
The message "Important Battery Message" is no reason to worry. It simply shows that your iPhone's battery has been replaced. With a certified battery, you can usually start with 100% power and use your device without restrictions. With this notice, Apple wants to ensure that only authorized repair shops use replacement parts - but that doesn't change the fact that your iPhone is well equipped.
