Same here.

Using iris on the web. Want to stick with them for the time being. Really solid site IMO.

Using web client. Nostrgram and iris.

Damus users can zap me with no issues at all, right?

Using Iris on the web, my iPhone battery drained fast using Damus - so switched to using their desktop version on my laptop.

Try reducing/changing your relays. For me Damus is generally decent on battery usage, even though they’ve done little to optimize
