Comments on: Galaxy Nexus on Verizon Could Have Better Than Expected Battery Life? (Updated)

with newer CPUs, each core runs faster and consumes less power than
previous generations (on the same clock speed), which means cpu
intensive operations finish “faster” on a single thread. but when you
split the load on multiple cores, the time (and power) spent processing
threads will also decrease.

An example; if you have a task that takes a single core 10 seconds to
execute 10 threads, it should take a dual core 5 seconds in theory. part
of the power savings comes from the time saved in processing, and part
comes from improved battery life of each core.

some modern designs also designate a “lower power” “helper” core to do
simple tasks and other tasks when the device is on standby. that also
reduces the power consumption considerably (also in theory). some future
designs also will include an additional helping core (probably for
background garbage collection in the case of android). meaning there
will be 2 full fledged cores, and 2 “lower power” cores, making the chip
a quad core…

it’s also worthy to mention that Android 4.0 ICS and future Android
distributions will fully utilize the GPU for UI rendering, relieving the
CPU from those nasty rendering tasks. while GPUs generally consume more
power than CPUs, the time it takes the GPU to render graphics is
exponentially shorter than that of a CPU. This will also result in more
power savings. ICS will also fully utilize all the cores, allowing tasks
to finish in a shorter and other cores to handle garbage collection.

However, when a Gingerbread device gets an official ICS updates, with no
bugs. then, and only then, will we be able to test out those theories.

For those who are concerned about LTE power consumption, all the above
does NOT apply to the power consumed by LTE. The power saved by the OS
on tasks is insignificant compared to the power consumed by the LTE
radio. I’ve read that Qualcomm (and others) is working on a 28nm LTE
modem embedded in their chipset. Now THAT is what you should be waiting
for before you jump the gun. If it were me, I’d wait for a device with
the new chip, which should also be powerd by ICS (or later versions).

As an owner of a dual-core, I have to say battery life is way more important to me than HD screen resolution,

Who removes “r u mad bro” comments? It is very annoying but time spent that way is inefficient..

My DroidX can hit this one day and be dead after a couple hours the next. This screen means nothing.

That really does sound true, I think you are right…

I thought only the GSM version was available so how does this person have an LTE version?

I have no idea what Kellex is replying to because both top comments have been flagged, but I liked his post because Kellex is a boss!

Are you retarded?? That’s the point of a Nexus device.

Depends on what the 4G radio is considered part of. I’d argue it’s probably part of Android OS, but that’s my thought.

Just because they say the screen is 720p doesn’t mean it’ll have superior quality. 720p is just the resolution, and HD is pretty much a gimmick. Look at the superior quality screen in the Motorola Xoom. That thing is a joke. With all that being said I’m not saying that the G Next won’t have a nice screen.

Probably better battery life because there is no BLOATWARE LOL

I think that is not true.
Phone idle comsumed 6% of battery capacity.
It means phone idle consumed 57.75mAh (= 1750 x 0.55 x 0.06)
As I know, phone idle consumes under 5mA.
As a result, phone idle consumed the battery for more than 11 hours.

And if the user used browser application for “the surfing” and the picture of “battery use” have to show that application. but it doesn’t.
I can see only android keyboard application
It does not make sense.
It’s a lie….

Verizon. Hi. Significant portion (maybe major majority) in the Android enthusiast community here.
Umm, yeaahhhh. If you could just go ahead and give us a date that we can give you our money and pick up a Galaxy Nexus, that would be great.
And, before I forget, Friday is Hawaiian shirt day. So if you’d like you can goa ahead and wear a Hawaiian shirt and jeans.
Peter, can I go ahead and talk to you about those TPS reports?
