Great designing exercise @Povilas_Grigas, thanks for sharing it.
It would be interesting to see how a phone like this would behave and perform in a daily environment, and knowing if it would be doable from a technical perspective.
The battery bump looks convenient to hold the phone and looks like it would make it less slippery, along with the two camera bumps.
Very nice touch rethinking the charger, why not make it transparent too, though? ๐ค
