one way to combat this is that manufacturers use cpu's with multiple cores; therefore requiring larger batteries to handle the power; therefore screen sizes can be bigger.

ios wouldn't gain much from quad-core cpu's since objective-c is inherently more efficient than java.
None of this post makes sense or is accurate.

First, Android currently runs native ARM CPU bytecode at runtime. There is no virtualization or translation at runtime. The same is true of iOS. There are no "extra steps" at runtime.

Second, iOS is capable of gaining quite a bit in performance with a quad-core CPU for applications that would benefit from it (multithreaded, computer-intensive applications). The same is true for Android. Objective-C or Java doesn't change this.

Android doesn't use Dalvik anymore.

ms bought bungie and cortana was the name of the ships ai in halo (seems like some cross-promotion marketing gimmick).

also, seems more appropriate for xbox but the xbox's wake up command is still xbox.

True, but at last check, 98.4% of devices are not running the version of Android that uses ART by default.

Dalvik doesn't use translation as stanley-88888888 suggested. Since 2.3, it's used JIT compiling.

Thank you Jason. That's what I was going to say. Yea, LOLLIPOP doesn't use Davlik but it's on like what... 4% of devices today?

4% is about half as many devices as run IOS 8. So, yes, the fragmentation is a larger problem on Android.

However, back to the original discussion; Dalvik isn't a JVM, and since 2.2 it has been a JIT. It's also worth noting that an objective-C method call is translated to a C call at runtime (even though it is compiled) and this initial call is slow, but it is cached with all subsequent calls. Similarly, JIT is fully cached for subsequent calls.

It's worth noting that ASM.js can actually outperform, both, Objective-C and Java on Dalvik (Haven't tested ART) in many calculations including partial summation and sparse binary tree traversal. So, it's not as simple as saying one is simply faster than the other.

That being said, I'd have to agree with NJBest that, for the right software, a quad core CPU can help both, Android and iOS devices.

In the U.S., yes.

No. The same thing applies when comparing iPhones to Android; the only difference is, the iPhone costs $700 and the Android also costs $700. Would you buy a chromebook for $700 that does your basics well when you can get a fully featured laptop for the same price? No.

Apple doesn't make a innovative product, they make a watered-down and underfeatured product and then charge a bunch because they know people will buy it anyway.

Oh yeah, and not to mention your argument of Apple products just "working" how you want them to is true to Android as well, you're just inexperienced in the platform. I've used both platforms extensively, and doing these things on Android is just as easy.
I cannot be the only one who sees the irony in your comparison.

In all of these Android vs. iPhone arguments, notice it is a single phone/OS vs. an OS yet many seem to forget that. It is one thing to argue against iOS if comparing it to Android, but you cannot compare the iPhone to the Android OS. The irony continues, nearly all who claim that Android is best are also arguing with the top Android handsets in mind (read: the premium Android handsets). It is almost as if everyone on the Android does not want to admit that there are many, many, cruddy Android handsets on the market. To add, even Android fanbois are divided over which handset/skin is the best.

If you want to compare Android against the iPhone, you gotta go with the Nexus as it is the only true Android phone.

And before I get called an iPhone fanboi, keep in mind that I would never own an iPhone. I am a die hard BlackBerry user.

For fun I just compared the specs between the N4 and the i6. Simply comical!

Then I realized that the i6 specs are equal to or lower than the old Galaxy S3 i just retired.

The "experience" of using an iPhone so many tout is like preferring Duplo blocks over Lego.
The thing is that the typical iPhone user really does not care about specs. Why the Android users do not understand this is beyond me.

Apple designs the hardware to run optimally with iOS. There is really no need to up the specs. Android is different in that it is not meant to run on any one particular piece of hardware. In reality, it is kind of meant to do its own thing. Handset manufacturers use specs to 1). optimize the performance of the OS because the OS is not built with any particular set of hardware in mind to begin with, and, 2). Specs sell (Android) phones.

Apple is a software company. Their business model is to also sell their own hardware. When someone buys an iPhone, or an iPad, or a Mac, sure they pay a premium, but with that price they get free access to most of Apple's software offerings that are not only increasingly narrowing in on parity between all of their devices, but also are apps that operate so close to the OS they might as well be a part of the OS. Messages, as an example, feels as if it was built into the phone. Messaging on Android feels as if you are using an app.

Google gives apps away for free (and OSs, too). That is how they get people in. They then mine your information to sell you targeted ads. That is how they make their money.

It is a silly argument to make because they simply do not care. It is like going to a rodeo and trying to convince people that a car is better than a truck only to go back home to your car-loving friends talking about how stupid truck owners are.

There surely is a difference between GOOD marketing and BAD. Actual $'s spent means nothing.
No one said "Apple spent a lot of money and that ='s sales"... no... Apple spent money on a a GOOD ad campaign.

We do need to have a thread like this every now and then. We just need to try and keep the fan boys in check and discuss it like ADULTS.

It's just that Apple is real good at marketing. Real good. I currently use an iPhone. It works good. I really want a Windows phone.

-Cheers.
