iPhone 5 battery journal and torture testing

I think the best tests of a battery are real-world ones. Rob Pegoraro tested his iPhone 5 in everyday life and found that it matches up great with competitors. My favorite quote:

“Each figure beats any Android phone I’ve tested on an LTE signal, although some 3G models have done better.”

Daily iPhone App: djay for iPhone 5 brings new features to the wider screen

Algoriddim’s music-mixing djay app has been a hit on both Mac and iOS for a while now, so it’s not brand new by any means. But the iPhone version has just been updated with some new features, including compatibility with the iPhone 5′s wider screen. And while a lot of developers have been content to simply spread things out with the extra real estate, Algoriddim has gone the extra mile, and actually added in some functionality that takes advantage of the extra space. You can see the difference above: The new version has volume sliders on each side of the virtual turntables, and the BPM is represented for each track above those sliders.

There are two other big changes in the app that take advantage of new features in iOS 6. The first is that audio can now be routed within the iPhone, which Algoriddim calls a “game-changer” this means that the iPhone can send one signal out of its Lightning dock adapter, and another out of the headphone port at the same time, which means that with the right setup, DJs can listen to one track while another is playing. The latest version of djay, obviously, supports this. And the other change is that you can now buy and display music from iTunes right inside the app, which means users can pick up new jams without ever stopping the beat. Both of these features are pretty impressive, and make a big difference in how djay can be used to play music from the iPhone 5.

A look inside Apple’s Lightning cable

Apple’s iPhone 5 includes a new Lightning cable that drops the number of available pins from 30 down to eight. Besides its smaller size, the new cable is also reversible and lets you insert the plug without worrying whether it’s facing the right way. Apple says the cable has “an adaptive interface,” but doesn’t provide any additional information on this feature. Thanks to Apple Insider, which collaborated with cable expert Peter from Double Helix cables, we now know a few more details on how this adaptive interface works.

According to the report, the Lightning port likely uses the authentication chip within the cable to dynamically assign pins based on the cable’s orientation. When you insert the cable into your iPhone 5, the port determines which type of data is being sent and then assigns the pins based on the cable’s orientation. No matter how you insert the cable, the correct pin assignment is always applied.

Coverage is a great app to see where LTE is and where it isn’t

As high-speed LTE services roll out across the US, many are wondering when their neighborhood will benefit. The iPhone app Coverage (US$2.99) produces zoomable maps that detail 2G, 3G, 4G and LTE coverage across all four major US cellular providers: AT&T, Verizon, Sprint and, for those willing to unlock their iPhones, T-Mobile.

The maps are stored locally, so a data connection isn’t necessary. I used it to explore my Arizona neighborhood, the East Coast and West Coast. My first impression is that broad LTE coverage is still restricted to the biggest cities, and Verizon is clearly way out in front. AT&T is significantly behind (though working on it), and Sprint and T-Mobile are barely players. That’s likely to change as time goes on, and the app will keep the maps updated.

Comparing the iPhone 4/5 displays under a stereomicroscope

Scientist Bryan Jones of the University of Utah wanted to know if the iPhone 5 display really was better than the already-impressive iPhone 4 Retina display. Being a retinal neuroscientist and a photographer, he had access to a Canon 1D Mk III DSLR and a stereomicroscope that let him examine the two displays in detail.

Though it’s hard to capture in an image, Jones says the iPhone 5 pixels are much closer to the glass surface than the iPhone 4. This observation isn’t surprising as the iPhone 5 uses new display technology that combines the touchscreen with the display. This contrasts with the iPhone 4, which sandwiches a separate touchscreen layer between the display and the glass.
