Minimum RAM required for running /e/OS (now and in future)

I’m considering buying a Murena Teracube 2s. It comes with 4 GB of RAM. How does that compare to the minimum required for /e/OS?

Based on some reviews, it sounds like 4 GB would probably be sufficient for what I would use the phone for (calls, texting, web browsing; no gaming). But I’m wondering if 4 GB will still be enough several years from now.

Based on this and this, my understanding is that the Teracube 2s comes with a version of /e/OS that corresponds to Android 14. Does /e/OS have the same RAM requirements as the Android version that it was forked from? And is that regular Android or Android Go?

Although there’s no way to know for sure when Android 14 will reach its end of life, the trend seems to be about 3 years after release. So Android 14 may only have another year of support. What happens to /e/OS at that point? Does it continue to provide security updates for the fork of Android 14, or does it move up to Android 15?

My understanding is that 4 GB of RAM should still be enough for Android 15, but Android 16 will require 6 GB. In 2 years or so, when Android 15 reaches end of life, what happens to Murena phones with 4 GB of RAM?

Is it possible to upgrade the RAM on a Murena phone?

Welcome to the community. I would like to just address the one thing I guess I can safely answer.

From all I know there is no smartphone at all out there that allows for upgrading RAM.

Hello @jlstrecker, Welcome to the /e/ users forum

i still run /e/OS andoid 13 on a device from 2013 with 2 GB and Quad-core 2.3 GHz without issue.
what make you think about RAM inflatlation in android ?
I can be wrong, but i think it is more the apps that take opportunities of the growing hardware capacities.
When a new version comes, i always read on XDA that it run more smoothly than the previous.

On further reading, I might have been wrong about the 6 GB requirement. I’d found a few articles claiming that Google had announced that, but couldn’t track down the original source. And I’m not finding anything about it in the Android 16 Compatibility Definition.

That is helpful to know, thanks.

generally limitation to upgrade android is due to kernel generation
