Severe battery drain continues, iOS 13.2.2, iPad Pro

Any new suggestions for a fix? I’ve tried all those listed in online articles.

Have had this problem since installing iOS 13, and 13.2.2 did NOT fix this problem. I unplugged my iPad at 6:15am (after charging to 100% overnight). Started using it to check the news. At 7:45, battery was 72% and dropping fast. it’s 8:15am and I’m at 62%. I’ll not get to noon without full depletion at this rate. I’m having to charge at least twice per day or stay attached to wall plug.

I installed 13.2.2 a few days ago, so apps should have had time to “catch up” with the release. Backlight is set low (too darned low for comfortable viewing). Safari is the big user at 87%, followed by Mail at 12%. No other apps are open. Safari has 4 tabs open, two of which are Apple. I continue to hope (foolishly maybe) that each new release will fix the problem, which began with installation of iOS 13. In another discussion, someone mentions re-doing a setting (clearing something?). I have not tried that yet, but don’t recall specifics and can’t find that discussion. Any help will be appreciated. iPad is my primary computer, and I need to be able to move around with it during the day. I don’t use Siri (some discussions blame Siri, I blame Safari).
