iPad (5th generation) iPadOS 16 when it runs out of battery (0%) when I plug it in the charger and it turns on,it shows 100% but then it shows a 5% low battery warning then when I turn it off and on again it’s at 1%,why?
As described, your iPad battery may have a fault, or may be reaching the end of its usable life. If the battery has failed or is failing, the iPad may unexpectedly turn-off - or may not successfully boot to a running state even when connected to its Power Adapter.
Are you able to use the iPad while remaining connected to your Power Adapter? If yes, while monitoring the indicated battery state, disconnect the Power Adapter; if the indicated battery state suddenly falls, or the iPad shuts-off, this test demonstrates the iPad battery having reached the end of its usable life.
As the iPad5 is now obsolete, Apple no longer offers any hardware service or battery replacement options for your iPad. As such, should you choose to pursue battery replacement, you will need to find a third-party repair shop. These Apple support pages detail available hardware support for vintage and obsolete products:
Obtaining service for your Apple product after an expired warranty - Apple Support
iPad Repair & Service - Apple Support
Given the age and status of your iPad, your best and most cost effective option is to consider replacing your iPad5 with a much newer or current model of iPad. In so doing you will benefit from a fully supported device capable of running the current version of iPadOS - and with it the majority of currently available Apps.

Those are the symptoms of a failing/failed battery and are to be expected considering the iPad's age (9 years as it was released in 2017).
Note that because of the iPad's age, Apple will no longer support or repair the device as it is considered obsolete by Apple. You may want to find a third-party repair shop that will replace the battery. Also note that due to the cost that may be involved, it may be worth putting the cost of the repair towards a new/newer/refurbished iPad. All future repairs will need to be done through a third-party. It doesn't make a whole lot of sense to pump money into an obsolete (according to Apple) device.
Very much the same symptoms I encountered when our iPad 5's battery failed. It could only run for 12-13 minutes on a "full charge" before shutting down.
バッテリーが劣化している。
Congrats...you've just repeated what I just said in my post to the OP.
Be proud.👍
