iPhone 4

When it comes to battery life, Apple's official iPhone 4S specs are a little bit dodgy. According to Apple, the iPhone 4S has one-hour of extra 3G talk time than its predecessor, but the same battery life as the iPhone 4 when it comes to basically every other feature. iLounge decided to investigate how the iPhone 4S improves upon the iPhone 4 in some categories, and how it falls short in others. The tech site put the devices through an extensive battery test and discovered the iPhone 4 actually has a slight edge over the 4S when it comes to battery usage.

In a 3G Data test the iPhone 4S failed to outlast the iPhone 4 in Audio Playback, Video Playback, and Video Recording. The iPhones were pretty even for FaceTime and Wi-Fi with the iPhone 4S clocking in slightly better for Cellular Calls. The chart above shows some of the comparisons for AT&T.

The mystery as to why Siri is exclusive to the iPhone 4S just got a little more interesting. 9to5Mac ported the voice command system from the iPhone 4S to the iPhone 4. In the video below, developer Steven Troughton-Smith demonstrates how Siri looks on the device.

9to5 claims it can recognize spoken commands and speak back to the user. The only problem is Apple's servers are not authenticating commands from the iPhone 4 hardware. Apple fans have been debating whether other iOS devices like the iPad 2 can handle Siri's AI. 9to5's discovery proves there are no technical reasons for Siri being exclusive to the iPhone 4S.

New and existing Sprint customers can pre-order the iPhone 4 with iOS 5 for $99 starting on Thursday. The iPhone 4S can be pre-ordered at 12:01 AM PST (3:01 EST) on Friday via their online store. AT&T or Verizon customers can visit Apple’s website or call 1-800-MY-APPLE to order the iPhone 4S tomorrow.

The iPhone 4S features Apple's dual-core A5 processor, 8-megapixel camera, 1080p HD resolution video recording, iCloud and Apple's new voice command assistant Siri. The iPhone 4S is $199.99 for the 16GB model, $299.99 for the 32GB model and $399.99 for the 64GB model. All prices require a new or upgraded contract.

The new iPhone that Apple announced yesterday impressed some and disappointed others. Though not everyone was satisfied, the new iPhone 4S will hit the streets with a number of impressive, exclusive features. While the list of new features is long, those most touted by Apple are the new iPhone's speed improvements, hence the "S" moniker, for speed. What many customers don't realize is that a one of the main speed improvements in the iPhone 4S won't apply to Verizon and Sprint customers.

As Apple informed us at yesterday's keynote, 3G data download speeds on the iPhone 4S are up to twice as fast as the iPhone 4. This is a result of the fact that the iPhone 4S is capable of HSDPA download speeds up to 14.4Mbps, while the iPhone 4 has a max of 7.2Mbps. The important thing to note here is that Verizon and Sprint are not HSDPA networks. The iPhone 4S will run on CDMA on Sprint and Verizon, not HSDPA, and thus will have the same download speed capability as the iPhone 4.

The iPhone 4S is not the "highly-anticipated" iPhone Apple fans were waiting for. It's safe to assume many fanboys were disappointed by Tim Cook's announcement, but Apple is sticking to its claim that this is the "most amazing iPhone yet." It didn't deliver a new "teardrop" design, or many of the other features we were promised, but it does have the rumored 8 megapixel camera and A5 chip. Hate it, love it or just don't care, here's a list of all the specifications and features for the new iPhone 4S.
