Take ipad4, iOS 10.3.3 system as an example. The specific steps to check the battery health of iPad are as follows:
1. First, turn on the computer, connect the computer with the iPad with a data cable, and download and install software that can detect hardware information on the computer, such as AISI Assistant.
2. After the software is opened, click the "Device Information" option, find "Battery Details" in the device information list, and click again to view the specific life and detailed charging times of the iPad battery.
3. Or make an appointment for battery testing at a local Apple direct store, and you can get a more detailed test report at the direct store.
Under normal circumstances, if the iPad is used normally within one year, the battery health will remain at around 95%. If the iPad is used excessively after purchase, the battery of the iPad may drop to about 80% within two years. If you find abnormal battery health after buying a new iPad, you can ask for a refund within 7 days. If the iPad is purchased through Apple's official channels, Apple will generally support 14 days for no reason to return it.
This answer applies to most of Apple's tablet models.
