Have a look at the manifest (use an app like this) and see if any of the services sound relevant to the functionality you need like 'Boot' or 'RunService', etc).
Using the fulll component name of the service that sounds relevant, via Shell run:
am startservice --user 0 the.app.you.want/.Boot
If the service is not exported (you'll see this in the manifest too), you'll need to use root or ADB WiFi to bypass that.
Assuming you starting playing the same day you installed it, and haven't moved devices/emulators since then, you can check when you installed PGR.
In stock Android, this information is hidden, but there are apps that dig deeper and let you view this information. Applications Info (Android, free and open-source) is one of these apps, but if you don't trust it, there are others available you can search for.
Applications Info - Found it on fdroid
Bad Pixels - App to check if any pixels are not working.
CCalc - Calculator
HW-Manager - outdated UI but gets the job done
Lit - Literotica app for android
PalmCalc - App which can convert currency, units, time zones, etc.
Text Aide Very under rated xposed module. It let's you select any text from any app and find it's definition, open as URL, TTS voice, dial, search in Wiktionary, Wikipedia, Google, Bing, Facebook, DDG, GitHub, StackOverflow, Youtube. These are opened in a small pop-up window so that you don't have to leave the app.
It also supports Macro Expansion.
First try to clear system cache. Instructions here: https://www.t-mobile.com/support/devices/android/samsung-galaxy-s10/wipe-cache-partition-samsung-galaxy-s10
Leave your phone alone for two days. If clearing the system cache does not help try following these. Here's what I did to tame the battery drain:

Also note your phone takes a day or two to adjust with these new settings so let your phone learn. You will see a big spike on the first day, but gradually gets better at management.
If problem persists, battery is the issue.
Here's an app that can help you find intents:
https://play.google.com/store/apps/details?id=com.majeur.applicationsinfo
http://api.wahoofitness.com/ is for the iPhone versions, not an Android version; there is no list of intents there.
If you want to discover what intents are available for it, each of which might or might not work for you, you don't need to go to javadecompilers.com to decompile the app. There are some apps on Google Play that will display the Android Manifest or otherwise list intent targets available, such as Applications Info and Stanley.
It's not necessarily possible to tell from the info in your screenshot. The "app name" isn't guaranteed to be unique. If you scroll down further, what does it say that the app was installed by? If it's the Play Store, tapping on it should open the store to the specific package. (You can then "share" the app from the Play Store to get a link including the ID.)
It it's not Play Store, there are several other ways to find the package ID, the easiest being an app like this one from F-droid (also available in the Play Store).
There's a list linked from Sending Intents and AutoShare can import many. You can discover them from an app's manifest (there are some apps that will display the Android Manifest or otherwise list intent targets available, such as Applications Info and Stanley) but it's better if the software authors actually bother to document what they can do (and take requests for new ones): extras might be used to control them, and extras aren't explained in the manifest.
Install applications info. Scroll to relay or search for relay. It will show that ID name.
