Why do some manufacturers of smartphone have a non-removable battery in their phones?

An integrated battery is more reliable. The biggest source of failures in removable battery phones was the contacts between the battery and the phone. Remove those, and while it now takes tools to remove the battery, they’re not going to fail. Less service calls.

A large source of service problems with removable batteries was damage to the battery while outside the phone. Not removable, less service calls.

A removable battery needs packaging so that it is safe to carry around outside the phone. But phones use LiPoly pouch cells, which are literally a plastic bag full of toxic corrosive chemicals that can easily catch fire or explode if you puncture the bag and contents the wrong way, so that packaging needs to be fairly tough. And that means it costs money and takes up space. So, if you remove the packaging, you can fit a lot more battery into the phone. Remember, there is a premium on battery life on smartphones, and most of them have only barely acceptable battery life anyway. Exploding batteries cause lawsuits, and they explode less inside phones (Samsung learned the hard way that they only explode less and they still have to be very careful).

There is a big, big premium on having a phone that fits in people’s hands. That means it can’t be too thick or too heavy, and the ‘phablet’ style are mostly used by people who tend to carry a handbag or shoulder bag to put them in. So, if you have to fit the extra connectors and three layers of extra packaging into a phone (one layer each side of the battery, and one to protect the works of the phone while the battery is removed), it gets too big and heavy to be a nice product that people will buy.

Integrating the battery makes it possible to build a waterproof phone. That’s actually a very cool feature, and means fewer service calls from water damage.
