This is a most excellent place for technology news and articles.
I literally bought an iFixIt kit to open my phone up (for a screen replace rather than a battery swap, but still) and could not get it open after an hour+ of trying. I'd definitely believe it's because I'm inexperienced in modern phone repair, but I'm not a generally unsavvy person. I build computers and mess around with tech as a hobbyist. I had to take it to a shop and return the kit. It's definitely not an easy process for some devices.
