I'm aware and I have. It's been helpful, but I tend to get into the habit of checking and messaging friends at random when I feel I feel slightly bored. Secondly, they'll often send me links and Youtube videos that I can't open. I'll likely reinstall it again in specific situations, like when I'm traveling abroad. Thirdly, the battery life on my phone lasts a few days without Signal running in the background. I've had the setup I have for about two months and it's working for me, at least right now.
