Why hasn't any company made a smartphone that has an ultra efficient CPU and on a big battery?

Why would anyone need a quad to octo core phone? Who's going to run autocad on a phone?

Please, someone make a modern 0.1W SOC.
 
So that they can brag how much better their phone is compared to other phones pretty much e-peen. I doubt most people that have the latest phones use anywhere close to the full cpu speed. All they know is that their phone is "faster"
 
I think the new droid maxx is shooting for that idea. It has a quad core snapdragon s4 which is a fairly proven CPU, paired with a stock 3500mah battery. They are claiming 48 hours of battery life.

I think it would be really awesome to see a quality dual core that got amazing battery life.

My gnex is only a dual core and it is super fast, so you don't really need much more.
 
Even though CPUs are getting faster, they are also better on battery life. The reason is the CPU dies are getting smaller, faster and using less power. The same with batteries. Getting better in size and performance. You could always root you phone and downclock the CPU.

think about the battery life on that thing!
The extra cores are basically turned off already when not in use. They turn on when you need them.
 
But if I took away cores and clock speed from my phone then I wouldn't be able to use half the applications that I do...or at least it would be really slow at it. Plus the extra cores and MHz only suck up substantial power if they are used. If all I do is run an ebook reader or document readers/editors on my phone my battery is barely touched. If I fire up epsxe I can burn through a battery in about an hour and a half...but if I didn't have the processing power I do on the phone I wouldn't be able to run epsxe at all.
 
As has been said, having a really powerful SoC doesn't mean it's always under heavy load and sucking the battery. On the contrary, having a powerful SoC just means it can do tasks faster and more quickly race back to an idle state that uses negligible power. The new LG G2 gets impressive battery life despite using a 2.3GHz Snapdragon 800 quadcore, one of the top 3 highest end SoCs available right now.

I've had a lot of Android devices and they are just now getting to the point where they are not ponderous and laggy. They really need a decent cpu to be not frustratingly slow. Even Tegra 3 devices feel slow now.

I don't understand the obsession with battery life, just plug it in when you go to sleep. Any modern phone will last a full day.
 
This is what ARM A5 and A7 are meant to address. Also the Huawai Mate has an amazing 4000 mAh battery which allows the phone to reach 80 hours usage as measured by GSM Arena.
 
I don't get it either. Battery life has stayed something towards constant from first 600MHz single cores to modern 1.5GHz quad cores. I would very very much like to see a 1GHz single core done in modern lithography methods and very high efficiency without the encumbrance of ridiculous core count or clock speed. I only use my phone for instant messaging, irssi and email, so something like that with a very lightweight android ROM (without gapps) would be optimal for me if it helped keep the battery life sensible. That, and I really don't care if it's thicker than high-end phones. If having a plastic screen makes it less prone to shattering, I wouldn't mind that either. I'm not sure how much high resolution displays affect battery life, but 800x480 is totally fine IMO.

Essentially, I want a minimalistic Android phone with focus on good fit and finish despite durable/less shiny looking materials.

Another point I find annoying is the megapixel war. I would much rather have a 3 megapixel sensor in a camera that has half the amount of noise in comparison to higher pixel density sensors.

I don't think Tegra3 was the problem as much as the flash used with it in most designs. My dual core TI4430 OMAP wouldn't be laggy if it had 2GB or more of RAM but the Gnexus is from 2011 IIRC so can't expect too much from something that old I guess. I just gave up trying to use chrome that often.

But for me the battery life in my Gnexus sucks mostly because of all the mobile issues with my provider. Sprint may have "unlimited" data but good like using any when 3G is all you get and it's shaky even with that. I turn data off when I don't need it and my battery can last me all day with moderate texting.

You forget about the biggest power suck in a phone... the screen. Screen resolution and size has increased.... which means more power usage.

Having more applications loaded in memory does not use more power.... the DRAM has to be keep charged anyways.

Check out the HTC One Mini, it sounds like it might be what you're looking for. Great build quality and a beautiful screen, similar to the HTC One. It has a 4.3" 720p display, Snapdragon 400 with a DC @ 1.4 GHz and an Adreno 305, 1 GB of memory (really wish it was 2 GB, but it's still snappy), a 4mp "Ultrapixel" Camera (same one as the HTC One though it lacks OIS), 16GB of internal storage, and a 1800 mAh battery. It's basically a smaller, gimped HTC One.

The development is limited at the moment, right now there is only a Rooted Odex/DeOdex Rom with the AT&T variant and the WWE variant (no AT&T bloat) and a modified kernel (they're waiting on HTC to release the source). Someone is working on CM 10.2 so which will hopefully be out soon.

I got mine yesterday and the battery life is pretty good in my opinion, I made a post about it on the XDA-developers forums here:

http://forum.xda-developers.com/showthread.php?t=2445367

Also, 800x480 is pretty bad. Just look at the Galaxy S2. Once you see a phone with a 300+ DPI you won't want anything else.

I'm not sure does half of this significantly change battery life, just theorizing. However, from my own experiences not having .gapps installed on CyanogenMod 10.1 improved battery life significantly on Samsung Galaxy S. I think some phone with good ROM support and a bulging huge aftermarket battery, like Nexus 4 would be nice enough for me.

I assume a lower resolution panel can do with lower backlight brightness since it has a less dense LCD assembly in front of the backlight, hence why I mentioned the resolution. I assume it's also less stress on the GPU no matter is it 2D or 3D usage. If OLED would be of any help, I really wouldn't mind that either with some minimalistic white on black-theme. For some reason I find the OLED pentile matrix in my Padfone 1 quite cute, it sort of reminds me of CRT days and never bothered me.

I have a ZTE Blade, it's a smaller phone with 800x480 and I think it's bordering towards redundant in pixel density. I don't use tiny fonts or browse websites in desktop-mode so I don't need or want massive PPI. Thanks for the recommendation though, looks nice!
 
I attached a 3500mah battery to my OG Droid. Sounds like the OP exactly lol.

Why not just switch the batteries or drop it in a dumb phone when the smart one dies or get an external battery pack?

My friend was able to use his HTC One for over a day I believe with some custom kernel
 
The already make phones like that. There's just isn't much market share for them. Look at the BB Q10. It fits your title description perfectly and with new dark theme the battery lasts even longer. Yet nobody gives a hoot. The Moto X seems to be going that direction as well.
