to continue from 2 posts up, I decided to browse MR exclusively today for some time. During browsing MR only, I lost 7% in 16 min and back of my iPad was warm. This was without any kind of content blocker btw.
edit: after manually closing Safari, I opened it again and browsed other sites and lost 2% in 12 min. This is not scientific, but MR site definitely eats up more battery without a content blocker. This just begs for use of blocker. I know mods browse the forum a lot since I got caught twice just today, but they need to be more on top of this kind of thing.
