Report: Qualcomm's claim on SD820's power efficiency doesn't mean double the battery life Comments

Don't get mixed up and confused... Everything gets connected to the SoC so they all get instructions on how to operate... Everything also get connected to the battery as it's the main power source...
If the SoC drains less energy it's gonna improve your devices usage time to some extent...Unlike the S810 which just heats up and drains your phones battery...
How long the usage time improves is yet to be seen in up coming S820 devices...

Or that my monitor is powered by the PC because of the DVI cable... Your 'logic' is highly flawed.

Oh, Snap HeatDragon! Its finally back with SD820. We need cooling capability not more efficiency.

I would assume that the screen takes most of the power, then maybe the SoC, and then RAM and Memory.
Yes DDR3 and DDR4 even as low power version eat a lot of battery power.

Actually everything on a smartphone is somehow connected to the SoC and it's the SoC that makes everything to work... Hence if the SoC uses less energy that should result in more usage time...
It's all logic...

I can't believe this! Who would be stupid enough to interpret this??
So, if you reduce your electricity expenses by half, do you reduce your overall expenses by half too? What about car fuel, water, newspaper, won't they cost the same as before?
A negative point of this new era is that anything can go viral, and anyone irrespective of education and intelligence, can access the internet.

GoToSchool, 04 Sep 2015Hahahaha so some people interpret twice as efficient as twice the battery life? There's a worl... moreYeah, agree. But what about the massive heat?

hahahah, 04 Sep 2015double eficient means that when prossecor eat 10% from your battery will now need 5% in use ... moreLearn English before saying someone is wrong. Prossecor is processor. U should be You and energie is energy.

Honestly even when you're using an embedded PC Board as a headless server, twice the efficient hardware doesn't mean half the power bills, there's always more stuff connected that sucks wayyyy more juice.
The websites should honestly just take a voluntary online course in logic if nothing else.

double eficient means that when prossecor eat 10% from your battery will now need 5% in use and the rest of energie will be used from display wlan and other chip in phone >>> if u take a phone with same hardware and just change the prossecor that will be few % better and not double

Hahahaha so some people interpret twice as efficient as twice the battery life? There's a world of difference between theory and practice.

I read in some articles the cpu 30% efficient and for the gpu 40% power and efficiency

Twice as efficient with double the performance would mean the same energy drain with double the bang.
The efficiency is performance per watt, while double the performance with the same efficiency means it drains double the power.
Double the performance per watt without increase in performance would mean double the life (providing the rest of the phone does not consume power).
Just for people interested in this.

Look, "twice the power efficiency" doesn't --even-- mean the --CPU-- uses "half the power as before". It means given the --same-- PERFORMANCE LEVEL (IPC), the power usage of the SoC will be half what it was. But if this SoC is 50% faster than the previous chip, it will still use 50% more than that "half" value, so still 75% of the original Chip. And that's before you take anything else into account like 4K screen, etc.

Anonymous, 04 Sep 2015The new Snapdragon 615, 808 and 810 are not enegery efficient like the Snapdragon 801, 805. S... moreAnd of course there was no need for more powerful cpus so 805 was more than enough. Of course, it's unacceptable in modern insanity standards so they had to use something way worse.

The new Snapdragon 615, 808 and 810 are not enegery efficient like the Snapdragon 801, 805.
So the new Snapdragon is gonna be energy efficient like 801 and 805.
So one step back and one step forword.
Going no weare?
