Occasionally there will be a popup saying the phone is putting apps to sleep to save battery. Why doesn’t it just do this all the time? Why does an app need to be “awake” if I am not using it?
Usually connectivity reasons. If an app is asleep, it can’t receive or send notifications, so there would be absolutely no “background” tasks or receiving messages, etc.
Some of that is for data theft reasons, like someone else stated, but definitely not all.
How can they spy on you if they aren’t free to run in the background.
The real answer is: because the OS lets the app decide whether or not to run in the background. And those “free” development frameworks sheap app developers use monetize via background data collection, so make sure the “run in background” flag is set at compile time. So you get flashlight apps that require your location, microphone and background functionality.
Why does an app need to be “awake” if I am not using it?
Because you aren’t the user. You are the product. An awake app steals your data.
Some general examples: Any active navigation keeping track of your location if you switch apps. Pebble monitoring notifications to be sent to a smartwatch. Email or chat client periodically checking for messages.
There is a Developer Setting in Android to instantly kill off-screen apps, but that would make multitasking a hassle.
On that note, what I have witnessed is the opposite, phone OS being overly eager to put apps in sleep / idle mode, to the point of ignoring user settings of “do not optimize battery” and “allow background processing”. Many (most “normal”) apps handle notifications through Google, but many FOSS and independent apps need to run in the background to check for messages, updates, etc.
App devs control this.

Battery saving mode can accomplish that, if you will.
Some apps, however, need to stay “awake” to catch notifications or do some background processing needed for their usual functionality.
Imagine if you were using a navigation app, put it in the background, and after some time, put it on the foreground and it had to start the whole process of locating you and calculating a route to where you were going.
That being said, most apps don’t really need to do anything in the background, except for collecting data about your behaviour.

Wait my phone collects data about me?
I thought the covid vaccine did that.

What did you think the 5G chips in the vaccine were for? Same thing as in your phone.

It’s 5G either way
