Battery respecting - private instant messenger (lemmy.zip)

I've always known that SMS are not encrypted and that they are not the safest way of communication. I tried using signal with others all on graphene os, but all phones seem to have their battery drained heavily due to graphene having to run signal in the background for instant notifications.

What do you all use as a safer daily alternative to SMS for mild sensitive info that doesn't drain the battery?

Preferably: trusted, privacy respecting, free, bonus if FOSS

Thanks for the recommendation. I wonder why no one is trying to make an updated version of this app, something similar to it. Seem very neat. I wonder if it is still secure because it is 6 years not updated...

    For the security aspect, I've skimmed through the code, it seems the "building blocks" that they are using (security primitives) are still relevant as of today. Namely I've found AES, ed25519, Hmac. The code itself is mostly taken from Text Secure (now Signal) at a point when they've decided to drop SMS support in order to focus on their own network (bypassing SMS).

    Personally I'd trust it more than raw SMS at least. I think I'd mostly trust it.

    I use Element/XMPP/Signal mostly though. In fact I've stopped using Silence few years ago.. Somehow thinking outside of the SMS box now.

    Guess I'm staying with battery hungry signal...

    Graphene won't let me give it access to sms

    I will try simplex, and see if it drains battery less. As of bow they seem to be tied for battery drain.

    I've tried it out of curiosity, it works for me. I had a link where they recommended clicking though, to fix it and to make it work. I don't see it on your screenshot. I think I got a (slightly different) warning with a link when I tried to open Silence as an app.

    Regardless, it was essentially to open Settings > Apps > All Apps > find Silence > click somewhere (I forgot where exactly) to enable the potentially very unsafe thing of full SMS access. I think it was on the top right where I needed to click in the last step. Afterwards, Silence can be selected as the default SMS handler.

    That being said, I personally mostly use Signal and Matrix nowadays. The phone lasts for.. 2 days probably? IDK. I'm not really happy with either messenger BTW, but it's the best shot for now, for me
