battery life

Hello ~ Have you had the battery changed? If so was it done by Apple or one of their Authorized Service Providers ? It seems it is not an original Apple battery or was installed improperly. This is an excerpt from the article you came from…

*An Unknown Part  message will appear if the battery installation is incomplete or if the battery:

• Was replaced with a nongenuine battery
• Was already used or installed in another iPhone
• Isn't functioning as expected

An additional message might appear that says "Apple has updated the device information for this iPhone." This means that Apple has updated the device information maintained for this iPhone for service needs, safety analysis, and to improve future products.

These messages don't affect your ability to use your iPhone or your battery.
