I just bought this ipad for 6 months. whenever I charged from like 50 it's normal but when it reached 80 It always slowdowns and it happens many times. I don't know why and I restart many times. But why when it reaches 80 it takes like 20 minutes and it still the same. Please help me
iPad Air, iPadOS 14
We have seen several reports of iPad Air4 battery charging being apparently limited to approximately 80% of full capacity in some circumstances.
Whilst unlikely, perhaps you have a problem with your Power Adapter. Start here:
If your iPad won't charge – Apple Support
Do you leave your iPad connected to its Power Adapter for extended periods? If so, this is not of itself an issue - as the iPad will optimally manage battery charging. When connected to a Power Adapter for an extended period of time, such as when used in Kiosk or PoS (Point if Sale) applications, iPad will change its charge management strategy - and reduce the maximum battery charge level to about 80% of maximum capacity. This strategy is intended to extend the life of the battery by reducing chemical ageing that occurs when the battery is continuously maintained 100% charge. As soon as a “normal” charge/discharge pattern is resumed, charge to full capacity is restored.
If your iPad has paused charging at ~80%, simply disconnecting the Power Adapter from the iPad for several seconds may trigger completion of the charge.
Other reports seen within this Support Community suggest that temperature may be a contributory factor - to which the Air4 seems particularly sensitive; the iPad is designed to reduce the charging rate if the temperature is too high for optimal charging. Whilst purely speculative, it is possible that the recent iPadOS update has erroneously changed the temperature calibration for your iPad. If so, a future update may correct this irriation.

Recent changes to iPadOS may have altered the charging strategy of your iPad.

Welcome Athidaya,
Thank you for using Apple Support Communities. Based on your post, your iPad slowly charges when it hits 80%. We'll do our best to assist.
If your iPad slows the charge, it could be a few different things. This could be related to how you've been charging your iPad. How are you charging it exactly? Apple recommends to use the charger that came with your iPad and an Apple power adapter. See: Charge and monitor the iPad battery
Since you've been experiencing issues with charging, check out: If your iPad won't charge
If it should persist, have you checked the charging port for any lint or debris that may be blocking the connection to the charger?
Hoping this helps out, take care!
why is my Ipad charging so slow?
