Yes. Lots of people here have much less than even 13GB physical ram. My Pixel 4a has 6GB. So reading a news about how apps have "only" access to 13GB sounds just weird when that's more than twice the total ram you have available.
They have 16GB of RAM physically, 3GB is reserved for AI. So yeah, only 13GB is usable by regular apps, even if you don’t care about any of the AI stuff.
It’s not about a single app, it’s about multitasking without having to reload apps.
At various times I’ve juggled between 4 apps at once on my phone. Say something like Messaging, Firefox, maybe a lemmy app, and Bitwarden for logging into something.
Have you noticed how expensive these things have gotten? Doesn’t it seems like charging you for more RAM than it necessary and then locking 20% of it away for “features” no one wants is a bad thing?
