Apple Watch to off load complex processing to the iPhone

Apple Watch to off load complex processing to the iPhone
Because the Apple Watch does not have cellular connectivity, it counts on the user's iPhone in order to communicate. Besides depending on the iPhone for this, those who have tested the timepiece say that it also off loads more complex processing needs to the processor on the handset. The timepiece carries an S1 processor that can handle things like basic math. By allowing the iPhone to handle other capabilities for the Watch, it saves battery life on the wearable.

The complex functions are sent from the Apple Watch to the Apple iPhone, and then sent back to the Watch using Wi-Fi. For example, some of the health data picked up by the sensors on the watch will probably get sent to the iPhone for analysis. The final result is then zapped by a Wi-Fi connection to the timepiece. In addition, Apple Watch users will be required to install an app that will help download apps and alternate watch faces, and also take care of the watch settings. This app might come with the release of iOS 8.2 or iOS 8.3.

The Apple Watch is expected to be released early next year, priced at $349. Apple has been showing off the device in France for Fashion Week there, but the watches on display are running a video instead of the OS, suggesting that Apple has some more work ahead of it when it comes to its timepiece.

And an iPhone will off load complex processing to its loyal customers and those loyal customers will off load complex processing to Android users because Apple's loyal customers can't handle complex processing.

What complex processing though? Like, I don't get this same old argument. My G3 lags when I'm switching from Google Now to Chomp, every time. But besides that, what are you doing on your phone that is SO COMPLEX? You guys act like you're processing for the White House on a phone. What are you really doing that's such a big deal?

IF your phone is prossesing for NSA then, yes is prossesing for the White House. That's not so complicated to prosses

Those are great articles but missing many new Android phones (unreleased in US) and the comparisons are quite terrible Why use browser benchmarks (Sunspider & Kraken) to compare CPU performance They mainly test Safari Vs Chrome Vs OEM's browser Unless if they are using the same browser, e.g. testing the iPhone 6 vs the iPhone 5S They should have used a CPU benchmark such as Geekbench for the comparisons (though ARM v8 has an advantage) The A8 is ahead in single core tests, but on par/behind in multicore tests ~4200 - Note 4 (Exynos 8433 ARM v8) ~3200 - NVIDIA SHIELD Tablet (K1 ARM v7) ~3200 - Samsung Galaxy Alpha (Exynos 8430 ARM v7) ~3200 - Samsung Galaxy S5 LTE-A (Snapdragon 805 ARM v7) ~2900 - Moto X (2014) (Snapdragon 801 ARM v7)

I think K1 ARM performance on single core with ARMv8 ~

It's so funny to watch apple make a clunky, complicated watch while Google made theirs simple and easy.

Yes, fandroids always talking about how the iPhone doesn't do as much, but then change their story for another device. So Android users are now happy with LESS options? Lol

No sht head, forcing a complicated UI on such a tiny screen is a stupid idea, something that the old apple would never do.

"For example, some of the health data picked up by the sensors on the watch will probably get sent to the iPhone for analysis." This is a bit incomplete. It's really: "All of the health data picked up by the sensors on the watch will be sent to the iPhone for upload to Apple's servers and then onto insurance companies for analysis."

Wrong company. Apple is the hardware company, remember? Google is the data mining company that makes most of its money off of your data.

Yet Apple is the company that met with all the major health insurance companies, not Google. Apple is the company that does anything for insane profits. After the death of Steve Jobs, there are no rules anymore, no Apple CEO who cares about right and wrong, about a better world.

So you can send some of your health information to your doctor if you want. And I will say you that data minig is not a insanelly profitable bussines, unless you have someone who wants to buy that data. (Or you are the big brother yourself.)

0xFFFF, I have looked at your claims about HealthData and Apple - guess what - you are a bit more paranoid than necessary... Data you input is voluntary and who it is that you want to share this info with is also voluntary. Apple will be in DEEP POOP if it sells, shares, or exposes this data to any entity - so I think Apple is really setting themselves on a trail they must tread carefully - Apple knows this. We'll see how this unfolds - I know many have been waiting for a one stop shop for all Health from any company (including my physician - he owns a Samsung Smartwatch, but mentioned he was waiting for iWatch). We'll see... But 0xFFFF, you're dissing it without any ground consistently - you got any alternatives?

So... offload processing to the iPhone to save battery life on the wearable? Wouldn't that tax the iPhone's battery more then???

It doesn't tax it much, so you still get half a day of battery :)

It's a good idea although I wouldn't be surprised if smart watches already did this for certain apps. As long as the phones battery is not affected greatly and the info doesn't take too long to get back to the watch.
