I'm interested in super thin flexible displays, pick projectors, waterproof from HzO, better battery tech (graphene anode), facial recognition.... The list goes on, quad processors are more of a natural evolution rather than evolution. I'm sure my next phone will have one but I wouldn't upgrade for only that.

Better battery life is always quoted when quad core is mentioned .... how come HTC have not announced the battery lfe/savings yet?

Just because you doubt it doesn't mean it will happen.
And How do you know what every person uses their phone for? If you have widgets a plenty running (Android) and play games etc I guarantee a quad core will help. And again, Software is driven by hardware. So please shut up, no body will make software for quad core yet because it wouldn't sell would it?
And probably right about asking joe public in the street whats in his phone, but I can also say that if it ran slowly and jerky would they not be saying I dunno but it's really slow coz my phones really slow and always shuts down. How can people not see that if the CPU is faster than needed then there are no restrictions in software development. Please stop just because you think you might never need one. It's really annoying.

It will be interesting how these phones translate into real-life battery. I suspect, if you use them a lot...not well. People are suggesting quad-core processors will use less energy than a single-core processor, for that to be true each core would have to use less than a quarter of the energy of the single core. I don't see it happening.

My friends with iPhone 4S have battery drain issues, their phones last half a day max. My friends with android often have phones that last even less and they've tried all sorts - less intensive ROMs, underclocking the CPU etc etc.

If it uses that ARM A15 or whatever it is called, the battery life will go up immensely via that one ultra low power core used for background stuff that makes up 95% of the day.

The main power drag is the screen with IPS displays generally the worst overall.
Compared to the screen, GPS, Wifi and even Data/Voice that low power mode might be bottom of the list on power requirements.

My wife's Iphone 4S lasts for days and she is constantly tapping the screen, and I have a desire HD which lasts a day but then again that has always been a poor phone from day one. And it is nearly 2 years old now.

Wrong. You posted in a thread about android phones. Thus is quite natural to assume you are talking about android. When apple release a quad core phone, it will also have no software that will make use of it.


The same can be said for apple users. Even more so infact.


We wont know for sure until these phones are used in real life situations. However stating four cores running at full pelt will use more energy that a dual core running at full pelt - I am not so sure. You havent taken into account that the quad core will finish its tasks in around half the time. Also this is true whether you are on about dektops, laptops, tablets, ios or android.

With apple no such choice. They give you a dual core processor, and then underclock it. Tough you have to live with it. At least with android we have control over the clock speeds etc. Ahh free choice, what a nice concept.


How about the operating system? The most important thing.

If you refer to the first post titled quad-core phones no where in the post does it mention that the thread is about android phones only.

I am also not going to take you up on your fandroid apple bashing as I simply don't care... Strange that on anandtech benchmarks for the under clocked iPhone beat the galaxy S2, must be that superior software I guess

The spec wars seem to be hotting up and new quad core phones from Huawei look interesting. Links below to two new high spec models expected in Q2/3 2012.

Since only android have quad core phone, what did you think this thread was discussing?..nice try, but no cigar.

My apple bashing, after I specifically requested that this didnt turn into a android v apple thread? You came here to try and put down quad core phones. Why are apple fans posting in this thread? There are no quad core phones from apple on the market. You only came here to knock what manufactures are doing with android devices. Sad really.

Yet it was slower than the motorola droid razr in some tests..what happened to the 'superior' software there?

^^^ and here I was thinking anybody can express their opinions, pro or con. As for a better battery efficiency of quad cores, surely one can manufacture a single core or if that's too complicated, 2 core processor with a low consumption core when in idle mode. It has nothing to do with the number 4. Because it's always about power x time. If 4 processors do something faster than one or two, they will also consume more power. Also 4 processors does not mean things done 4 times faster, there's always a synchronisation accessing shared resources to consider. 4 processors bring more computational power when all cores work simultaneously, but it will cost you in battery life.

There's not even a hint of lag on the SGS2. it's blisteringly quick. This is what Android should have been from the start. I complained about jerkiness on all previous Android phones, even when it occurs for a split second, but no more on the SGS2.

On that note, until software is written to utilize quad cores, I see no reason to upgrade. My SGS2 doesn't break much of a sweat.

Agreed, my s2 is awesome! The only people i've heard complaining about lag are the people who don't ever reboot their phone or at least clear their RAM once in a while when they have a shit ton of apps running in the background. Just tell them to buy i-phones, lovely little toys for people who don't quite get how tech works

I'll be getting the s3 asap. I'm due an upgrade around july/august anyway so meh, free stuff is free stuff. Also, because I work in internet marketing, SEO, Design, App development etc I need to have decent tech for the usual professional dick waving contest. With us lot, how many customizations you've made to your rooted phone and how much you've managed to over clock your big ass computer is what people will judge you on, not how shiny your car is or how much your suit cost

4S last for days? Exactly how?

My now second 4S runs out of battery in less than a day with moderate use

talking in black and white facts such as 4 cores consume more power is not really correct. If you consider old generation cpus against modern i7 cpus which are multi core you will find the power usage surprising.

multi core processing is about doing thinks more efficiently which normally equates to faster and in doing so will less to less power consumption over a less efficient system.

if a quad core CPU (if it were to use all 4 cores say) takes more power over a given task than a single/dual vcore CPU it will do it as a rule more efficiently thus saving power. not all cores have to run full power for every task

^^^ you are comparing old and new cores, i meant 2 or 4 new cores. UI should run on a graphics processor anyway and what is left is not much, unless you run really taxing background / parallel tasks.

Indeed but apparently expressing ones opinion is forbidden around these parts

Also OP, android will certainly not be the only quad core phones out this year, we will likely see both Apple and Windows phones using it and all my comments were aimed at hardware not the OS until you started to try and turn this into some sad fanboy war, I study engineering including ARM so have a great interest in hardware which is what my comments were based on.

Yes modern quad core chips are energy efficient but guess what the dual core versions are too, and if software was all 100% optimised for quad core then it would be more efficient but it never will be, just look how long quad core PCs have been out and still most software works better on 2 cores running faster than 4 cores running slower hence Intel's Turbo Boost.

Again this is just my opinion but it's everybody as valid as yours so please grow up.

No I won't shut up just because it doesn't please you... How rude...

At no point did I say what every person uses their phones for but if you bothered to look at data you see that most people only use a few apps, there are power users but these are few and far between.

Making software work well over 4 cores is difficult and you can never get even close to the performance as shown in synthetic tests.

I also didn't say I will never need quad core but ATM its not worth upgrading for IMO.

The problem is a level of parallelism. You can have preemptive multitasking, you can have multithreading, but processes and threads do not live in a vacuum. There are some situations when you have several computing intensive tasks that work independently and then additional cores will make a difference. But generally speaking, there's communication, dependency on availability of other results. There's competing over shared resources, etc. They all decrease a level of parallelism and thus a potential speed-up that additional cores can bring.

Indeed, marketing would have you believe that a quad core is twice as fast as a dual core hence why people sell computers on eBay by adding all the clock speeds together 4x2GHz is now 8GHz and so forth...

The above 8Ghz etc only looks stupid because its only really done on ebay and is not conventional.
I'm half surprised AMD and Intel don't do it.

Don't give them any ideas lol... I am also surprised that hasn't become the standard to sell processors.

Nothing wrong with expressing opinion. Its when the opinion has a clear bias that I have a problem with. Android may not be the only quad-core phone this year, but they are the only quad-core phones released to date. Thus discussing other OS's is guessing.

As for accusing me of turning this into a fanboy war, you should maybe read the second post in this thread. So maybe get your facts right.

The real issue here, is that whilst the electronic side of things have moved along at a fast rate, battery technology that been stagnant in comparison. If battery technology had moved along at a similar rate, or even slightly slower, then we wouldnt be having the current problem. Thus having to charge your phone on a daily bases has become the norm. Its something you accept when you buy a smartphone. One reason why I think this is the case, is that electronics were used in a desktop computer that was plugged into the mains. This power, efficient were not an issue. When mobile devices came along, especially smartphones, the battery became an issue. I think someone needs to look into battery technology, and produce a battery that can keep a smartphone charged for at least a week. Although in reality it will probably be smaller jumps. At the moment I would take a battery that would keep my phone charged for two days with average use.

I think motorola have the right idea, introduce a phone (razr) with a standard battery. Then introduce a bigger battery pack and back cover for the same phone. This will make the phone heavier and thicker, but at least the consumer has the option. Its a simple solution, using the current technology.

Haha, I wish there more people around could appreciate my modded dick. I have a SE Arc (modded and OC'd) and that does not lag either. Mind you my wifes modded and ZTE Blade which only has Arm 6 at 600 mHz lages very little. The 12 month contract on the Arc has 6 months left and I can't see any of the 4 phones featuring in my short list in August. Well maybe the LG 4x if, as expected the price has fallen through the floor and there is decent community support. What I really want is either the Samsung GS3 or the the Samsun Note 2, maybe the original note if the price is right.
