Does a bigger battery always mean greater weight & dimensions?

[Currantly]

So I'm currently considering a new mobile 'phone, but most new devices seem to be over 6 inches now, and not much thinner or narrower than they were a couple of years ago.

It seems like it's not possible to get a mobile that's something like the dimensions & weight of my old S5 mini; 4.5" (113.4mm) & 120 g, with proportionally more raw battery power (yes, I know battery management & efficiency are supposedly much improved )...?

I guess my height limit would be around six inches, if the extra weight gave that much better endurance. I know there are certainly other factors I'm glossing over, but it seems to me as if the real energy density of batteries isn't really progressing as fast as the other components...

Battery tech is pretty stagnant in the mobile space and I think to a degree that is intentional, if batteries are great we would have less reason to replace a phone.

In many cases the effective cost if replacing a battery in a phone these days, outweighs the cost of replacing the phone.

There is also the catch, while bigger phones have bigger batteries, they also have bigger screens, which of all the components, its the one that going to use the most battery, faatee/newer cpus and gpus are more energy efficient so they are less likely to significantly increase consumropn, some may even decrease, with the screen however, there is only soo much they can do to reduce the power draw.

You are going to be hard pressed to find a smart phone with significant battery life, 2 days is about the max you going to get, actually using the phone will significantly decrease that.

Phones consume more power, it is why they receive bigger batteries.

If someone tries to squeeze more power in the same volume, batteries tend to explode or do not last that long.

Packing a huge amount of lithium cells in a tiny space is a risk, it may affect discharge rate and the batteries ability to "vent". This can cause explosion if the battery is not packaged properly.

Yeah, I think lithium battery tech has pretty much reached its limit. How much bigger can 'phones get before we have to call them tablets? Seven inches, I guess. The next advancements will come with dry electrodes & super capacitors.

I'm not really asking for that much more battery life. I'd be happy with 1-2 days, with light/medium usage, in a smaller form factor (4-5 inches)...they can even make it a bit thicker if they want.

Yeah, that's the thing, years of market research has shown that thickness is the key factor for the majority of users, the market wants thinner phones, height/width are irrelivent to them. So in order to pack in batter and really usefulness to an extent, they are making phones taller and wider, but thicker pretty much sits with your low end budget phones that only have decent battery life because it takes 30 seconds to open WhatsApp.

Its that old addige of pick only 2, you not going to get a good phone with a small factor and decent battery life.
