Unfortunately, the first screenshot cuts off before it shows much in the list of what's using up battery life. It appears that number two on the list is Facebook. The FB app is a notorious battery drainer. I'd give some thought to getting rid of it and accessing FB through the browser. You also seem to be using the iPad for handling HomeKit and that seems to be using a lot of battery life. That would continue to happen in the background.
Also, based on the first screenshot, you last charged it to 100% on Tuesday at 7:46am. The screenshot was taken on Thursday at 9:04am and you're not quite to 25%. That doesn't seem "awful" to me. If you plugged the iPad in every night before bed, it would automatically back up to iCloud and be fully charged and ready to go in the morning.
