Why did all of the manufacturers decide to prevent the battery from being detatchable at the same time? It almost has to be pressure from government no? There is no seeming legitimate reason they should change it as such.

I think this has less to do with government surveillance and much, much more to do with simple corporate greed.

If you can’t replace the battery in your device, then your only choice is to buy a new one when the battery inevitably dies. Planned obsolescence in the age of portable tech.
