What future features would you like to see from mobile tech?

My answer to this would be removeable batteries, but not like they used to be, since companies are now making more flip phones and foldable phones and even making phones almost to the size of phabletts, there is no reason why they couldn't make a normal phone of metal, magnetise the back and have a tiny cell battery inside the actual phone to keep a current there like they do with PC motherboards.

Then a 2nd part of the phone that has the battery in it which can be replaced, and have it so once it connects together it is powered by wireless charging.

Make it so it slots in under the camera's, most wouldn't see the connection since the back never usually gets looked at especially when taking pics or recording video.

That would leave even more room inside of the main part of the phone for more features and give the end user aka the customer the freedom to swap out batteries when needed.

I'm sure with today's technology it could be achieved.
