> I ran Graphene without a Sim card for 2 months and as soon as I added a Sim card (with of course, difficult to vet networking) the phone is always hot and the battery life reduced by half. Might be a coincidence but also made me rethink how I feel about Graphene

Strange you're being flagged since it's easy to find many other people on the graphene forums reporting the same (unresolved) problem.

Doesn't mean it's guaranteed to be limited to graphene in scope, but definitely seems to be a prevalent issue for some yet-to-be-determined reason.

Possibly related, does anybody know if graphene is vulnerable to Pegasus?
