I would say that for battery life alone, that probably wouldn't be for you yet. Regarding other apps, while they do work, it's quite a severe downgrade from android/iOS - mostly, I think, because the pinephone is so low end hardware. I do use it as my main phone, but that's only because I find hacking it worth those sacrifices. In your case, you'll probably want to wait for the Librem 5 to see how it compares, or for pine64 to release a buffed up pinephone (if they ever do that).
