They do, but they’re incredibly prone to breaking when you pull and sometimes they’re just hard as shit to grip so you have to use a screwdriver to twist and pull.
I don’t think I need to explain why that’s so dangerous.
As someone who has changed hundreds of iphone batteries, the adhesive sucks. At least they changed to a different adhesive around iphone 8 because alcohol does wonders on it. I don’t even attempt to pull the tabs on those anymore.
May I ask how you do that? Do you just…douse the battery in alcohol? There isn’t much of a gap between the adhesive and the battery in my experience, so it just sits inside the chasis and rolls around. I haven’t had any luck with that but I’m probably doing it wrong.
