In daily use I saw that my daughter's T5c used significantly more battery in near idle applications and noticeably less battery in heavy use applications and battery life was comparable to her iPhone 6s. But shortcuts were taken in manufacture and the charging port's insulation crumbled away so now it is just a collectable in a drawer. One side note is the cpu had no heatsink, just that black coating you find on ram.

Is there any ARM that can run full Windows at the level of a decent, midrange x86/64 cpu? My biggest disappointment is the Cherry Trail phones didn't run native Windows 10 as they clearly were capable of, albeit slowly. It would be nice to see Tremont in a phone, but even with full x86/64 W10 support, a video out, and usb-c for a hub, a lot of phone apps would still be missing and sales would likely be disappointing.
Funny you should mention Windows 10 support. I have this obscure netbook which has a Cherry Trail CPU (Intel Atom X5-Z8300). Let me tell you, you would never want to run Win10 on a platform like that unless it was running on anything faster than eMMC storage (which this netbook has and most smartphones still used at the time) even if the CPU itself was fast enough and supported Win10.

On topic, yes one of the biggest problems with Intel/AMD/Nvidia trying to scale down their existing architecture is that they struggle with [idle] power consumption. Hence there really was no reason for ASUS to go Intel again beyond the Zenfone 2 for their smartphone lineup. Samsung already has problems curbing power consumption with their Exynos SoCs and tacking on a scaled down GPU architecture is a very risky move.

It's interesting how different the scales of power are. On my Broadwell laptop the CPU idles at roughy half of what the RAM does. ~600mw vs ~1200mw. At least according to powerTOP under Manjaro 20. On laptops, the CPU's usage is already very low relative to everything else at idle. In phones though, 1800mw would only last 2 or 3 hours, with the screen off. In fact, knowing how much power the RAM takes on a notebook, I'm not surprised phones often have such dismal bandwidth.

"We should make it clear that NVIDIA is a good company, and we respect their attempted transition into being a smartphone company." - Roy Taylor, AMD

Before that T5c became my daughter's (due mainly to unacceptable reception with gsm network where I work) I played with it for a bit. The light use where it ate up the battery a lot compared to the snapdragon 800 in the Lumia Icon I had as my primary was playing and streaming music and podcasts. The heavy use was web browsing desktop format where the T5c was roughly as fast and didn't use much battery where the s800 would get hot it was draining so much battery. T5c never got hot. Still didn't have that good a battery since I put more hours streaming/playing audio than looking for something better than the paper to read at lunch. And the T5c would drain more just sitting there in my locker over the day.

Maybe a ram sized chunk of Optane could be used to quick wake from hibernate to save battery, but wouldn't be cheap. Well it would be cheap if Intel weren't milking that stuff so much. 4GB should be like $10.
But better to leave phone to ARM. It is cheaper and runs the phone apps people crave at least as good. I bet if somebody at Microsoft came on stage at a presentation with an ordinary looking phone they could put in a dock that was connected to a keyboard, mouse and monitor and it ran desktop windows as fast as a 6 core Phenom2 they would get boood off the stage. They would start throwing rotten produce when the guy would start showing all of the wrong apps for a phone getting email, making calls, browsing the web, and somebody would yell "Where's Snapchat? Tinder? Why no podcasts with iheart Radio?" Then the phone would interrupt to connect with another phone windows style and warn of imminent restart from some microcode update. There would be double notifications popping up like a virus infected pc running windows me. It would be a mess.

I used to have hopes for x86 phones running Windows. Still bothers me when they get badmouthed. Now I'm just another sheeple. I should toss that Icon, taunting me with it's camera, great os-native full featured audio, and it's fluid os that still seems a decade ahead of ios13. At least it's app selection is going straight into the toilet. This is a search for Hulu:

I don't know why people game on phones. Daughter sure likes to, but she cares much more about brand and social stuff than any performance specs outside of battery life. She is big on that one.
FPS alone isn't enough to win AMD many fans in the phone segment. There are different priorities.
