@PeterCxy @fribbledom I think some heavy media files are the culprit, which it has to keep cached not to decrypt them every time. According to dev menu, Element uses 1,7 Gb on my phone, I do not have a lot of chats, but I do like to paste screenshots into chats with Firefox on desktop and it pastes them as PNGs. Also not an issue for me as I have a lot of free RAM.
