Deep in its lengthy review of the iPhone 5, iLounge has performed an analysis on the battery life of the iPhone 5. The site tested the device under a number of conditions, including both cellular and Wi-Fi web browsing, voice calls, FaceTime calls, video recording, and video and audio playback.

The phone performed fairly well but iLounge found battery life struggled when transferring cellular data or making voice calls, which they speculated was due to a weak signal:

if you’re using your iPhone 5 in places a with a very strong (4- to 5-bar) LTE or 3G signal, your cellular battery life may approach that number, but if not, the cellular antenna will struggle to maintain a signal, and fall well short. Because LTE and 3G/4G towers are in a state of build-out flux right now, our tests suggest that many LTE users won’t come close to Apple’s promised numbers.

iLounge has the detailed results on its battery testing in its iPhone 5 review, but unsurprisingly, mileage will vary greatly depending on a number of factors including health of the battery, signal strength, screen brightness, and other considerations.

Reports about the high-profile split between Apple and Google that saw Apple replace its Google-powered Maps app for iOS with its own solution have continued to trickle out, with AllThingsD now reporting that the lack of turn-by-turn directions on Google's Maps app for iOS was the key motivator for Apple.

[M]ultiple sources familiar with Apple’s thinking say the company felt it had no choice but to replace Google maps with its own because of a disagreement over a key feature: Voice-guided turn-by-turn driving directions.

Spoken turn-by-turn navigation has been a free service offered through Google’s Android mobile OS for a few years now. But it was never part of the deal that brought Google’s maps to iOS. And Apple very much wanted it to be. Requiring iPhone users to look directly at handsets for directions and manually move through each step while Android users enjoyed native voice-guided instructions put Apple at a clear disadvantage in the mobile space. And having chosen Google as its original mapping partner, the iPhone-maker was now in a position where an arch rival was calling the shots on functionality important to the iOS maps feature set.

Apple reportedly pushed hard for voice navigation in Google's maps on iOS, but Google was unwilling to hand over the functionality without concessions from Apple. As detailed by other sources, Google was seeking greater control over the mapping experience on the iPhone, such as Google branding and Google Latitude integration, concessions Apple was unwilling to make.

Combined with the deterioration of the overall Apple-Google relationship and Apple's concerns that Google was collecting too much information from iOS users, Apple ramped up its mapping efforts in order to bring its own turn-by-turn directions to the device, ultimately deciding that it could afford to do away entirely with Google's maps.

While Apple's MacBook Air is already extremely thin and the new Retina MacBook Pro has reduced the thickness of the company's flagship notebook by 25%, work naturally continues on new ways to shave even more thickness from future versions of Apple's notebooks.

Digitimes reports that Apple is working with suppliers on a new process that will enable the company to shave 0.15 mm from the thickness of the light guide used to distribute lighting for the company's illuminated keyboard in the MacBook Pro and MacBook Air.

Apple will reduce the thickness of light guide plates for the illuminated keyboards in its MacBook Air and MacBook Pro models from 0.4mm currently to 0.25mm in 2013, according to sources in Apple's supply chain.

Since the current injection process for the production of 0.4mm light guide plates has been optimized to its limit, makers utilizing extrusion processes are likely to win orders for 0.25mm light guide plates, the sources indicated.

A difference of 0.15mm seems a negligible reduction in thickness that would by itself be essentially imperceptible by users if it were even to translate to slightly thinner overall profiles for the machines, but the company is likely pursuing the reduction for some purpose. Apple is unlikely to significantly alter the overall form factor of next year's MacBook Pro and MacBook Air, but combining small reductions in thickness for multiple components would pave the way for more significant overall reductions down the road.

Kyle Wiens from iFixIt speculates that the added thinness for the keyboard may help prevent the keyboard leaving residual marks on the screen when the laptop is closed.

Amid varied reports claiming that Google has been working on a replacement standalone Maps app for iOS to replace the bundled app included with every version of iOS until last week's release of iOS 6, The New York Times weighs in with its own sources claiming that Google is indeed working on a standalone app for iPhone and iPad and is hoping to have it available in "another couple months or so".

As was noted yesterday by The Verge, Apple and Google still have over a year left on their contract for Google to provide Maps for iOS, and thus Google was caught off guard when Apple announced in June that it would be replacing Google's solution with its own Maps app for iOS 6. As a result, Google still needs several more months to complete work on a standalone offering to be submitted to Apple for inclusion in the App Store.

The New York Times notes that another challenge faced by Google stems from its desire to build 3D imagery into its upcoming Maps app for iOS 6. The functionality was added to the Google Earth app several months ago, but moving it to the more traditional mapping app will require additional work.

Another complication, according to a person with knowledge of Google Maps: Google would likely prefer to release a maps app that includes 3-D imagery so it is comparable to Apple’s. But Google has 3-D images in Google Earth, which is a separate app with a separate code base from Google Maps, so it would take some time to combine the two.

Apple's new Maps app has come under significant criticism for a number of issues, including incomplete or poor imagery, errors in locating points of interest and even cities, and a lack of transit information. As with Google Maps, users can report problems to Apple to help improve the product.

Mac Otakara reports that it has received information from a source indicating that representatives of Apple and Foxconn have been working to source unknown parts from a company with expertise in carbon fiber materials.

According to my source, some engineer of Apple and Foxconn Technology came on Japanese company, which has carbon production in mid-March, and they requested to develop some sample.

I don't have information which is ordered by Apple, source told the number of parts is too large to be called "sample".

Rumors of Apple's interest in carbon fiber, which offers high strength at low weight, have been circulating for a number of years but have yet to come to fruition. Nearly four years ago there were rumors of a carbon fiber MacBook Air, and Apple patent applications have indicated that the company is at least exploring what could be done with such materials.

More recently, a pair of reports had indicated that the iPad 2 might gain a carbon fiber body. Those claims did not come to pass, although both reports had indicated that the information was rather sketchy in nature as Apple may simply have been testing the technology during the company's product development cycle.

With the hiring of Kevin Kenney last year as a senior composites engineer, speculation regarding Apple's plans for carbon fiber has continued to surface. Kenney had previously served as president and CEO of carbon fiber bicycle frame pioneer Kestrel Bicycles.

Amid widespread complaints over Apple's new iOS 6 Maps app, which replaced the Google-powered application that had shipped on iOS devices since the iPhone debuted in 2007, some observers have wondered how much of the shift was due to Apple's desire to reduce its reliance upon on Google and how much might be due to other factors.

In particular, there has been some speculation that demands by Google could also have played a role in Apple's decision, with the suggestion being that Apple may have been forced to roll out its own mapping solution a bit sooner than it had planned for if its contract with Google had been running out.

The Verge now reports that such speculation is unfounded, with Apple and Google having had over a year left on their contract for Google's Maps app. Consequently, Apple could presumably have continued using Google's app in iOS 6 as it worked to improve its own mapping product for a launch with iOS 7 next year.

For its part, Apple apparently felt that the older Google Maps-powered Maps in iOS were falling behind Android — particularly since they didn't have access to turn-by-turn navigation, which Google has shipped on Android phones for several years. The Wall Street Journal reported in June that Google also wanted more prominent branding and the ability to add features like Latitude, and executives at the search giant were unhappy with Apple's renewal terms. But the existing deal between the two companies was still valid and didn't have any additional requirements, according to our sources — Apple decided to simply end it and ship the new maps with turn-by-turn.

Apple's decision apparently caught Google off-guard, as Google is reportedly still several months away from having a standalone maps app ready for submission to the App Store.

With Apple's new Lightning connector on the iPhone 5 dropping to just eight contact pins from the 30 pins seen in the original dock connector and gaining the ability to be inserted in either orientation, many have wondered just how Apple has been able to maintain most of the functions of the original dock connector. Others have wondered why Apple simply didn't shift to micro-USB, an existing standard in a comparable form factor.

Developer Rainer Brockerhoff has been examining Lightning's technical features and over the weekend outlined his thinking on how the "adaptive" nature of the Lightning connector highlighted by Apple during the technology's introduction at the iPhone 5 media event has enabled flexible functionality with a minimum of pins. Brockerhoff notes that the Lightning connector appears able to sense what kinds of devices are being connected and to use chips embedded in the cable to assign pin functionalities appropriate for each situation.

- The device watches for a momentary short on all pins (by the leading edge of the plug) to detect plug insertion/removal.

- The pins on the plug are deactivated until after the plug is fully inserted, when a wake-up signal on one of the pins cues the chip inside the plug. This avoids any shorting hazard while the plug isn’t inside the connector.

- The controller/driver chip tells the device what type it is, and for cases like the Lightning-to-USB cable whether a charger (that sends power) or a device (that needs power) is on the other end.

- The device can then switch the other pins between the SoC’s data lines or the power circuitry, as needed in each case.

- Once everything is properly set up, the controller/driver chip gets digital signals from the SoC and converts them – via serial/parallel, ADC/DAC, differential drivers or whatever – to whatever is needed by the interface on the other end of the adapter or cable. It could even re-encode these signals to some other format to use fewer wires, gain noise-immunity or whatever, and re-decode them on the other end; it’s all flexible. It could even convert to optical.

Double Helix Cables has now shared with AppleInsider a mapping of the pins on the two sides of the Lightning connector, demonstrating that this adaptive assignment of pin functions is required for the reversible nature of the plug.

"Take top pin 2 for example," he wrote in an e-mail to AppleInsider. "It is contiguous, electrically, with bottom pin 2. So, as the plug is inserted into the iPhone, if you have the cable in one way, pin 2 would go into the left side of the jack, flip it the other way and the same pair of pins is going to match up with the other side of the jack (as the electrical contacts in the iPhone's jacks are along the bottom)."

The adaptive nature of the Lightning connector may explain to some degree the rather high cost of cables and adapters for the new standard, as the $29 and $39 adapters for connecting 30-pin dock accessories to Lightning-equipped devices are required to contain hardware capable of working with the dynamically assigned pin functions. In addition, the adaptive nature indicates that the same Lightning interface could evolve over time to support new technologies within existing hardware.

iFixit and Chipworks have partnered on a teardown of the A6 system-on-a-chip, Apple's custom design that powers the iPhone 5. While several of the high-level details such as 1 GB of RAM and a dual-core CPU paired with triple-core graphics have already been shared, the teardown confirms all of these details with high-resolution images showing the various components of the chip.

Perhaps most notably, the custom ARM-based CPU developed by Apple for the A6 appears to have been manually laid out on the die, an expensive and time-consuming process but one that can offer greater efficiency than automatic layout.

- When compared to the rigid, efficient layout of the GPU cores directly below it, the layout of the ARM cores looks a little homespun—at first.

- Generally, logic blocks are automagically laid out with the use of advanced computer software. However, it looks like the ARM core blocks were laid out manually—as in, by hand.

- A manual layout will usually result in faster processing speeds, but it is much more expensive and time consuming.

- The manual layout of the ARM processors lends much credence to the rumor that Apple designed a custom processor of the same caliber as the all-new Cortex-A15, and it just might be the only manual layout in a chip to hit the market in several years.

The report also takes a look into the die, where it confirms that the A6 is manufactured using Samsung's 32-nanometer HKMG process that was trialled earlier this year with the A5 that made its way into the third-generation Apple TV and the revised iPad 2.

Finally, iFixit and Chipworks took a look at a number of other chips from the iPhone 5, sharing die photos from Qualcomm's MDM9615M modem and RTR8600 RF transceiver, a Cirrus Logic audio amplifier chip, and Murata's Wi-Fi/Bluetooth module incorporating a chip from Broadcom with other components.

9to5Mac reports that one of its readers emailed Apple's marketing chief Phil Schiller regarding scratching of the iPhone 5, an issue that we documented on launch day. The issue is most visible on the black models due to the anodized slate color scratching off to reveal the silver color underneath. According to Schiller, such scratching is "normal" with use.

Q: I love my Black & Slate iPhone 5, but I've been seeing some scuffs, scratches and marks throughout the band around the phone along with many others. What should we all do? Any plans to fix this?

Schiller: Any aluminum product may scratch or chip with use, exposing its natural silver color. That is normal.

Not only are users experiencing scratching on their iPhone 5 bodies with normal use, but a number of complaints have surfaced regarding units being scratched right out of the box. According to a a thread in our forums, several readers have reported scratching or scuffing out of the box before the device had even been handled.

While Apple set a company record by selling over five million units of the iPhone 5 during the device's launch weekend, it clearly could have sold even more if supplies had been available. Pre-orders for the iPhone 5 sold through the company's launch day stocks in just about an hour, and shipping estimates for new orders have been sitting at 3-4 weeks since soon after pre-orders began.

Bloomberg reports that Apple's tight supplies at launch are a result of the new in-cell technology being used for the iPhone 5's display. The technology integrates the touch sensors directly into the display rather than adding them as a separate layer, allowing for thinner displays.

Apple used the technology in the first major iPhone overhaul since 2010 to make the device more svelte, an attribute that helped lure a record 5 million buyers in three days. Yet producing in-cell screens is also more painstaking than earlier screen types, contributing to bottlenecks.

KGI Securities analyst Ming-Chi Kuo had previously noted that shifting to in-cell technology would simplify and shorten the display manufacturing process, but low yields of the new implementation have challenged Apple's supply chain partners' efforts to meet demand. Although LG and Japan Display were able to ramp up production, Sharp experienced the most significant difficulties and only began mass shipments of the display into the supply chain two weeks ago.

Reuters reports (via TheNextWeb) that Google's executive chairman Eric Schmidt has denied claims that the company has already submitted a Google Maps application to Apple's App Store.

Google Inc. has not submitted a new Google Maps application to Apple Inc after the iPhone maker dropped the use of it in launching its newest device, the head of the world's top search engine provider said on Tuesday.

The rumor emerged last week shortly after Apple launched iOS 6. In iOS 6, Apple replaced the Google-based Maps on iOS devices with the company's own solution. Apple's Maps have since drawn criticism for areas of poor coverage.

Schmidt told reporters, "We have not done anything yet" and stated that they've been talking to Apple for a long time and talk to them every day.

Update (Sept 25, 1:34am PT): Bloomberg has a slightly different interpretation of Schmidt's comments. Schmidt said that it was up to Apple to approve the app, though they claim that Schmidt declined to say if Google Maps had been submitted.

“We haven’t done anything yet with Google Maps,” Schmidt told reporters in Tokyo today. Apple would “have to approve it. It’s their choice,” Schmidt said, declining to say if the Mountain View, California-based company submitted an application to Apple for sale through its App Store.
