Whether or not your Apple device is in its original AppleCare warranty period or is covered by AppleCare +, you can verify that its current coverage may be the first step in the repair. Here's how to check what's covered and what's not.
As many as have learned over the years, Apple devices repaired outside AppleCare can be a costly endeavor, especially in view of current laptop repair. Nothing is cheap when it is tied or soldered to a logic card, so you will probably hope your repair tab will be downloaded by Apple. If it is not, things can be costly, fast.
Thankfully, AppleCare's coverage is pretty simple, and you can control all of your devices in one place.
How to check AppleCare status for a single device  There are a couple of different ways you can take to check the AppleCare coverage for a single device. One requires that you have the device serial number at hand, but can be done from any computer with a web browser and Internet connection. The other means that you download an iPhone or iPad app.
If you know the serial number of the current device, go to checkcoverage.apple.com and enter the serial number in the current box. You also need to fill in a security code to show that you are human.
When you are finished, click the "Continue" button and the device information will be displayed, including whether it is covered by AppleCare or AppleCare +.
How to Check the AppleCare Status of All Devices
If you'd rather see all your devices in one place, without entering any serial numbers, download the app "Apple Support "from the App Store and sign in with your Apple ID.
When the screen is loaded, press "Check coverage."
You will see a screen showing each device associated with your Apple ID and a note about whether it is currently covered by AppleCare or AppleCare +. You can press a device to see additional information about it.
