Jailbreak stores have never felt like a particularly strong illustration of what's possible due to their tiny user market - I'd love to see what developers would do if even for a period we could use these devices to anything remotely like their potential.
But really, imagine how much power these things have and if you could actually run a free (as in freedom, in the GNU sense) OS on them and really get access to all that power in a handheld device. Only if.
I have an M1, which is like N-times faster than the laptop I write this on. Yet it collects dust because I'd rather continue to use this old dinosaur laptop because that M1 macbook is a locked down, very fast, shiny Ferrari, but I just want a Honda Civic I can do whatever I want with.
I'm pretty sure battery performance would drop significantly if root was too easy to achieve. The temptation to run "that one more background service" would be far too much for most apps, both free and otherwise.
To get good battery perf out of a device, you need to be extremely good at saying "no", even if that "no" comes at the expense of user freedom and features. Free software is usually extremely bad at this by design, although there are exceptions (Graphene OS comes to mind).
On Apple devices, core system services are written by Apple itself. That puts pressure on the software development side to care about battery perf, as that is what users want (and what increases sales). If software is written by 3rd parties with their own business goals unrelated to device sales, I'm afraid "featuritis" and lower development costs would win out over efficiency, as it usually does in such circumstances.
When you just have to focus on a handful of hardware platforms and when you own the hardware and software, this becomes much, much easier.
Well, except Android :P
My phone runs a build of AOSP that I compiled myself. I can go change the source code to do whatever I want (and I do). It's pretty cool that that's possible IMO. To be fair, the drivers are closed-source
I would assume that an iPhone has similar amounts of unwanted background apps and would also be able to gain battery life instead of losing it if rooted. Obviously if you install spyware, you lose a lot of battery life. Funnily enough, I remember that a few years ago, people were surprised to find that uninstalling facebook increased battery life because it behaved much like spyware.
No offense, but this is one of the most absurd things I have ever read on a hackernews discussion.
I bet if I could get root on iOS I would get even better battery life as I kill off services related to iCloud and other background processes I don’t want running.

There is zero evidence that this is the case. In fact saying “no” to root allows more services and things running on the device than I may want.
Also, iPhones have 20% smaller batteries for the same battery life, but there could be multiple reasons (maybe combined even) for this.
