In this article, Mr. Litchfield explains it on an engineer's level why sealed batteries are an oxymoron.
IPhone users get a better return on their investment which means they upgrade more frequently and don't generally experience the issues. Those that have bought used iphones, generally don't notice an issue until months down the road. Same with editors of these sites. They have access to new handsets far more frequently greatly decreasing the experience of failed batteries.
I happen to live near an Ultrabattery plant. I have a friend that works there. Batteries are big business as is oil. We have the technology to get far more gas mileage out of vehicles than we do now. However, secretly, what would it do to oil if we obtained close to 150 mpg? Same with batteries. We can make them larger to last longer on a charge, but the design of the battery is still the same. Manufacturers tightly sealing vulnerable components inside a phone, means dollars for them and service centers. This is the real motive here.
As Mr. Litchfield explains, I am one of the users that has to hold into my phone until the end of contract. Almost every phone I've owned, has had to have the battery replaced 15-18 months into contract in which there is no warranty. If these were sealed, it would have cost money that is better spent on putting towards a new phone.
Apple is king of devising profits. Their marketing has allowed consumers to accept the design.
Those of us that have been around electronics most of our lives, understand that a chain is only as strong as its weakest link. Batteries are this link and the manufacturers want it that way for their benefit.
