The fuss is that 3rd party apps need a persistent notification to stay alive. But, because Google owns pixels, it can skip that step and be less intrusive/visible, which others can not.
Because (from what I’ve read) battery optimization may still kill them, depending on the phone.
Persistent notification was added in response to android 8+ background restrictions. You didn’t need it before.
Apps that need to be constantly alive do that to avoid being killed by the system on android devices that are not stock or pixel. Apps like tasker, accubattery, Internet speed meter, adguard all target the latest android version 12 or higher.
We are on android 14. You can not install apps targeting android 5 from the playstore today.
Unfortunately, that will mean your app can be killed on many smartphones from device makers like xiaomi, Oppo, and huawei, which have aggressive battery optimization. I had this issue on a redmi device where background apps would be killed unless a permanent notification was present.
The WireGuard and tailscale apps work great for me without a persistent notification.
I haven’t tried wireguard. But, I should give them a try and see how it goes in samsung.
I was under the impression that the “Disable battery optimisations” feature was to prevent exactly this. Maybe I misunderstood what it does, but a bunch of apps designed to run in the background tell you to disable this functionality for their app for this very reason.
That is for applications that need access to a LOCAL_SERVICE while not in foreground. That’s like Geolocation or screen orientation. VPN is not one of those. You can kill the foreground application from the recent apps by sliding up.
No real VPN app needs to have an application window and a background service (same thread) running to provide a VPN. If it does, it is doing something else not related to VPN.
If you want to add a pause button, applications can add custom tiles.
