iPad 9,7" 2018 battery drain with iPadOS 13

[Frank7f]

Anyone else experiencing battery draining or at least battery lasting sensibly less in comparison to iOS 12 on their iPad?
Some minutes ago I checked notifications on my iPad, spending 10 minutes, and the battery status passed from 30% to 23%. Prior to the update I can remember it lasting even 3 days without a charge, now I can make it last 2 days at best with a low usage. The battery wear level is still pretty low, around 95%. I bought it around early 2019 and I haven't used it much really in the first months.
I've installed all the iPadOS 13 betas without any sensible reduction in battery life, and I am sure enough that this is happening from the last public versions of iPadOS.

I clicked yes but it is a bit difficult to tell for certain.

Update
Since I've written this post I've disabled localization of a lot of app which weren't using it, and also disabled background content updates for some apps for which I didn't care updating in background. I can't tell if this has helped but I think the autonomy has improved if not completely returned to the previous condition. I think that decrease could be caused by a lot of factors, maybe more than one at the same time, for example apps not yet optimized for iOS 13 etc.
