Thank you, johnrel, for your feedbacks and suggestions here, as well as your keen interest in the upcoming One UI 5 roll-out.
As we waiting patiently, I would recommend to follow below step-by-step to limit your apps, especially with locations services and background operations.
Google Play Services is a sort of central switchboard for the Google apps built into Android and those installed separately. Instead of each app performing the same tasks, they all work through Google Play Services to get tasks done. As a result, Google Play Services is constantly running in the background of your phone, routing data and otherwise keeping the phone running smoothly.
A) Check the apps on your phone and delete any apps you don't use regularly or don't need in a day. The fewer apps you have, the less usage Google Play Service gets.
B) Set Background Restrictions.
Step 1. Navigate to Settings.
Step 2. Select Battery.
Step 3. Tap Battery usage.
Step 4. Tap the app that says it's being using in the background, and then choose Restricted to restrict battery usage while in the background.
Some apps may be slower to load when you turn off background services. If you need an app to load instantly, leave it on.
C) Set App Limits to use Location.
Settings > Apps > Permission Manager > Location.
D) Apps Permission Manager.
Go through the other permission and toggle off any permission you don't want apps to have.
Settings > Apps > Permission Manager
E) Google Play Services Do in the Background.
Google Play Services enables conveniences like:
Single sign-on, so you don’t have to keep logging into each app as you open it.
Automatic file storage on Google Drive.
The ability to use Google Maps information and data without opening the app.
Security scans for third-party apps.
Location tracking tools so you know where you are.
Google Pay services.
And cloud game saves and leaderboards on Android games.
Before putting off Google Play Services because of the aforementioned lists, take the time to check and confirm whether you need them running in the background.
Google Play Services can't usually be disabled or deleted. Because it does so much in the background for so many apps, turning it off or removing it would probably cause your phone to break down, and apps would either stop working at all or not work at all. Instead, controlling what your other apps do in the background is the focus of managing Google Play Services. If you keep them in line, Google Play Services shouldn't use too much battery power.
