I installed #Signal and #Conversations_im on a clean install of #GrapheneOS on my Pixel 4a and measured the battery impact. The results are shocking!
Both messengers had only one contact: my regular phone.
I used my regular phone to send messages to the Pixel 4a (which was not used for anything else over the course of the experiment).
I always sent the same message via Signal and #XMPP (mixing up which app went first). In total I sent ~32 messages in intervals of 10mins to a few hours.

#Signal isn’t just AWS. It also has a hard dependency on Google’s push notification system (FCM) if you don’t want your battery to catch fire.
Signal’s attitude towards #UnifiedPush and #FDroid speaks volumes.
