The number one mistake I see with phone battery swaps

I've fixed over 50 phones this month and almost every single one had the new battery glued down WAY too hard, making the next repair a nightmare. A tech in my shop said 'more glue means it holds better,' but that's just not true for modern adhesive strips. How much pressure do you guys actually use when seating a fresh battery?

My buddy used to do the same thing with car trim adhesive. He'd use a whole tube when a few dots would work, and it just made a mess for the next guy. It's the same idea with those battery strips, you only need enough to hold it in place. Overdoing it just punishes the next person who has to open it up.

I get where @shane_knight is coming from, but on phones I've opened, those weak factory strips fail all the time. I use a solid line of adhesive so the battery doesn't shift and wreck the flex cable. A few dots just doesn't hold up to daily drops and heat.

Three years ago I watched a guy's iPhone X battery puff up and snap a flex cable because the factory adhesive was just those little strips and they gave out after a hot day in his car. If you're doing this for a daily driver that gets tossed around, a few dots is gambling with someone's data and screen repair bill. Plus half the time those "next guy" arguments are from people who just don't want to take their time with a heat gun and some isopropyl alcohol to clean up the extra adhesive.
