This is completely anecdotal, but I feel like using GrapheneOS has increased the lifespan of my phone. Or rather I should say, has allowed me not to have to upgrade as often in order to maintain acceptable performance.

I am still using a Pixel 4a 5G as my daily driver, and couldn't be happier.

I think the reasons are twofold:

1. Ongoing model support and release activity
2. Changing the way I use my phone

In regard to point 2, what I mean is that it has allowed me to dodge bloated OS updates, as well as forced me to use (usually) more performant FOSS alternatives to my previously relied upon apps. Additionally, because it encourages me to adopt a more secure mobile lifestyle, I'm also not using my phone for more intensive (and often more invasive) media and games.

What are your thoughts?
