I agree. It’s just the “Make it bigger and lighter” doesn’t make sense. If you remove the camera bump and fill it with battery you have a much heavier phone.

The only thing that would significantly add to the weight is a bigger battery

You said get rid of camera bump. That means making the entire device thicker because of the limits of optics. Batteries are already around 25% of the total weight so doubling battery life would increase weight 25%.

You want bigger everything and less weight.
