Random Battery charge level

Since yesterday, although my battery is charged around 70/80%, the charge level suddenly drops to 3/4% (not event touching the phone). Need several reboots to be back to it’s “real” charge level.

I’ve tried with my old battery, same issue (sudden drop of charge level without using the phone, and need to get off the battery or reboot a lot of time to recover the normal charge level…

Any idea?
Thank you

Act accordingly.
For the loose battery please read on here to find some hints.
