User level: Level 1 (5 points)Hi, I have an ipad air M3 and I've owned it for exactly a year. After 218 charging cycles, my battery health is on 89%.
Is it normal or should I be worried?

A reduction of 11% battery health for 218 full charge cycles is indeed greater than might be anticipated. Excluding other factors that can influence battery health over time, on the basis of charge cycles alone, you might reasonably expect a 4-5%% reduction.
"Battery health" is influenced by many factors - this value not necessarily declining in a linear fashion.
An iPad battery is rated to retain 80% of its original capacity (when new) after 1000 full recharge cycles. Any combination of charging that together sums to 100% equates to one full charge cycle (e.g., 50% + 20% + 20% + 10% = 100% = 1 full charge cycle).
As such, you might reasonably anticipate that battery health will decline by 1% for each 50 full charge cycles. Assuming a linear change in reported value, a battery health of ~95% might be expected in nominal conditions.
Other factors can influence overall battery health. High ambient temperatures can permanently reduce the battery's ability to retain full charge - as can maintaining the battery at 100% charge for very long periods of time that leads to chemical aging of the battery. Limiting the battery charge to ~80% of maximum is intended to reduce the chemical aging effect.

Independent studies have demonstrated that for devices in regular use, restricting charging to only 80% of maximum has little if any impact upon the overall longevity or health of the iPad's battery. There is no need to micromanage an iPad's charging strategies.
If you have any concerns for your iPad or its Battery Health you would be well advised to seek assistance directly from Apple Support - and request a remote diagnostic test of your iPad. 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 from Apple devices using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:

The battery drop is a bit unusual but u can be tension free. Nothing is wrong.
