We have had an iPad and iPad mini mounted in Launchport sleeves in our showroom for several years. It appears in both cases, the iPad's battery has "puffed up" inside the iPad's to the point that the screen is bulging. In one case the screen has a visible issue where the internal battery is pushing on the backside of the screen. They spend most of the time on a wall or desk top charger are rarely used enough to run the battery below 25%. Has anyone else seen this? Does it happen to iPad's without using a Launchport if left connected to a charger too long?
