iPad Air, iPadOS 26
Many factors can impact your iPad's reported battery health. Limiting the overall number of charge cycles is only one factor. Independent studies suggest that the iPad's Optimised Battery Charging setting provides optimum charging for common usage patterns.
Battery health is effectively an estimate calculated from many factors - as is displayed as a integer value (i.e. rounded down to a whole number). As such, the displayed value is likely to drop quite quickly from its initial 100% value as the iPad is charged a few times.
An iPad's battery is rated to retain at least 80% of its original capacity after 1000 full charge cycles - one full cycle being any combination of charging that together sums to 100% (e.g. 50 + 25 + 15 + 10 = 100 = 1 cycle). Simple arithmetic would therefore suggest that battery health will decline at about 1% for each 50 charge cycles - but this alone does not take into account that the rate of decline is non-linear.
Studies have demonstrated that restricting charging to only 80% of maximum has little if any impact upon the overall longevity of the iPad's battery. This feature does have potential benefit where the iPad is connected to external power for extended periods such as when being used in retail or kiosk applications.
If you are concerned, you would be well advised to seek assistance directly from Apple Support - and request a remote battery diagnostic test. You can contact the Support Team using the Support link at top-right or bottom-left of this page.
Alternatively you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to hands-on test and assess your iPad:

The information about your Battery health will be updated by iPadOS from time to time, especially after a firmware update or upgrade.
The battery capacity does not decrease linear, sometimes it stays at a certain value for a longer time, before it gets updated again. After two years, the battery capacity should be at least 80%.
This also depends on the use of your device.
