Ipad Battery stuck at 14% for over 7 hours, just changed to 13%

Hi,

My iPad has been acting very strange lately... it was on 4% when i went to bed and i awoke next morning and it was on 1%, that same day when i put it on charge it would only charge to 6%. Now, it gets even stranger, I came to the conclusion that I would let my iPad charge to 6% then I would swap chargers. This did work, however, it would then stop at a different number. Finally it charged up to 14 percent which is not a-lot but still a reasonable amount. I continued to use my iPad for seperate hours ahead,(the same day, this present day), and the battery was still on 14%. I have been using it for about 5 hours and only 5 minutes ago did it change to 13%. Just now it changed to 12 so its acting a little less strange.

i just thought i might report that, for i will be curious to know why...

Yours Sincerely,

Madeleine

(btw i got my ipad at the start of 2020)
