I remember back when you could take out your smartphone battery at any moment of your choosing. This used to be a very handy way to fix phone freezes (at least temporarily) and a fast way to get your phone to cool off when it got too hot.
Then came the new generation smartphones with the batteries built and locked in. Needless to say you can't take the battery out in case of a phone freeze. You will simply have to wait it out and hope it unfreezes, or wait till the battery runs out.
If the newer models of smartphones had detachable batteries, would you go for it, or stick with the built-in battery models?
