You want to shift to Android because you want higher moment of inertia and/or higher weight in your phone ? You would be a dream customer to many phone companies. Or perhaps you say all this in jest.
I also have an iPhone, but be fucked if I can keep hold of it, it's so light I can seem to actually get a grip on it for longer than about two minutes at a time.
I've had my eufges phone for over a year and still haven't broken the screen. I mate dropped his, same brand, different model, from a second story access platform from where it fell face down on concrete, the glass screen protector was cracked but the phone was fine.
I do not understand the obsession with lightness and thinness, but that's just me, and I suppose the other few thousand who've bought phones that aren't ultra light ultra thin ultra breakable.
So there’s a proven market for a rugged iPhone.

Your half-kg phone has trained your motor neurons in such a way that they are not prepared when you hold a ~100g phone. I suggest mixed-interval training. Use both phones regularly (you mention the half-kg one is your daily driver). An anti-slip silicone case for your iPhone should also help.
When I hold an iPhone, it sometimes feels heavy to me. I would say my experience is more representative of the general population than yours.
I had exclusively iPhone's for ten years prior, I couldn't keep hold of any of them. A pop socket help a lot.
And I'd argue I'm not alone, how many phone screen replacements do you reckon repair shops across the globe perform every day?
They're too fragile, and too difficult to take care of.
As for battery, stick a powerbank in your bag. Anker do some nice ones. I got 9 days out of one.
