I can't imagine the iphone is entirely powering down memory. Otherwise just unallocating memory won't change the power consumption.
Those aren’t the only two possibilities though.
Somehow, with 12GB of RAM, I can't get my iPhone 17 Pro to keep more than a few safari tabs open without having them refresh when I come back from an app or two, and it makes me want to throw my phone across the train (Where the internet often cuts out!). A lot of software has been squandering the massive hardware gains that have been made. I hope this changes when it becomes a lot harder to throw hardware at the pro…

Pixels only make sense if you are going to install Graphene. The Google OS is bloated with spyware.
On a Pixel phone you have only Google spyware. On another brand's phone you have all the same Google spyware, plus the spyware from that brand and a permanently locked bootloader.

Memory uses power, this is a major factor in why aggressively stopping things helps. There is a strong argument modern mobile goes too far for this.
This is an argument for having less memory on a hardware level. But once the DRAM is there, it uses power, whether or not it stores useful data or useless data. There's a reason why we say unused RAM is wasted RAM.

Powering down unused physical RAM is absolutely a thing on some systems. For one thing, it's required if you ever want to support physical memory hotplug. The real issue however is that the gain from not doing DRAM refresh is clearly negligible: it's no more than the difference between putting a computer to sleep (ACPI S3), or putting a phone to sleep in airplane mode - and powering it off.
Over investment in AI data centers is having a huge negative impact all over the economy. Other sectors are missing out on investment limiting their growth and stalling the economy. Companies have reduced staff prematurely on the promise of productivity improvements that have not occurred and lost customers to terrible customer service and declining product quality. Many hardware launches are going to be delayed or n…
Would love to know what sectors you would say are obviously under invested. Sounds like an opportunity.

With dram, you have to refresh every cell within a periodic interval. Usually this is handled in hardware. It would be a crazy optimization if unused pages weren’t refreshed. There would have to be a decent amount of circuitry to decide that.
I don't work at that kind of level, so I dunno if the juice would be worth the squeeze (sleep with DRAM refresh is already very low power on phone scales), but it seems doable.
