On average I get like an hour and a half of screen time per day. I use my phone to message people on Signal, I connect it to my bluetooth earbuds and listen to music or a podcast when I go for a run and I occasionally like to take photos. I don’t waste my time scrolling through TikTok for 8 hours like many other people unfortunately do. One week of battery life is pretty rare, but it has happened before. As I said, usually I get 2-3 days out of it when I it charge up to 80%. (charging up to 100% is bad for battery health, so I try to avoid it). I’m sure you will be fine. You can get a Pixel, install Graphene, try it out and give it back and receive a refund if you don’t like it. That’s the good thing about Pixels, installing a custom OS doesn’t void the warranty or anything like that. You can just revert back to the stock OS and everything will be fine.
Signal is finally delivering the stuff we have all been waiting for. First, they implemented post quantum cryptography in the protocol in September, then we got message editing, and now we will finally get usernames. Awesome!
