As mobile devices grow increasingly more capable and complex, battery life is easily one of the most important features in smartphones these days. Sadly, it’s also one of the biggest pain points with Apple’s iPhone lineup, as we have seen in just about every survey and study that covers people’s complaints with Apple phones. Because battery technology progresses so slowly — and because Apple insists on making its iPhones as thin as possible — battery life in iPhones likely won’t see any dramatic improvements anytime soon.
We’ve gone over tons of tips and tricks in the past that will help users extent their battery life, and we focused most recently on iOS 8 features that could help improve iPhone battery performance. We have also discussed some new measures Apple is taking to squeeze as much battery life as possible out of its new iPhone 6 and iPhone 6 Plus.
But sometimes it’s just not enough.
When it’s crunch time and your battery is running low, sometimes you need to do everything in your power to keep your phone running as long as possible because outlets are nowhere in sight. We recently shared a bunch of good emergency tips to consider when that happens, but there’s one important one that should definitely be added to that list.
One of the first things a person does when battery life is running low is reduce the brightness on the iPhone’s display, but there’s another simple step that should become second nature just like turning the phone’s brightness down. In the iPhone’s Settings app, go to General > Accessibility and turn “Grayscale” on.
Believe it or not, simply displaying colors on the iPhone’s screen consumes additional battery life, even if the screen’s brightness has been reduced.
Grayscale is a very smart battery saving feature that Samsung has introduced on its newer phones, and iPhone users can take advantage of this similar feature on their iPhones, though the process of enabling and disabling grayscale is more complex on the iPhone since Apple doesn’t yet have a special dedicated battery saving mode in iOS.
You can easily create a shortcut so that triple-tapping the home button on an iPhone will enable this feature. Simply open the Settings apps and go to General > Accessibility > Accessibility Shortcut and check the “Grayscale” option.
After trying to charge upward of US$2,000 for an iPhone 6, grey market dealers in China are slashing prices as Apple prepares to begin sales of the product in the country.
Apple will finally launch its iPhone 6 and iPhone 6 Plus in mainland China on Friday, a month after sales began in the U.S. and several other markets including Hong Kong.
In the meantime, grey market dealers in China had been offering their own stock of iPhone 6 models, smuggled in from other countries. Back on Sept 19, the day of the iPhone 6 launch, merchants in Beijing estimated the first incoming units could reach up to $3,000 or more.
Device Prices, a service that tracks China's grey market for electronics, said the iPhone 6 Plus once fetched a particularly high price. The space grey-color of the 64GB model was being offered at around 15,616 yuan ($2,546), or over double its original price, when it first arrived.
The silver 64GB version of the iPhone 6, on the other hand, was priced at around 9266 yuan (US$1,510).
But grey market dealers have since been cutting prices on the iPhone 6 models, after Apple made it known late last month that the product would arrive soon.
In some cases, grey market vendors are offering the models at an even cheaper price than Apple, according to Device Prices. The space grey 16GB version of the iPhone 6, for example, will cost consumers around 5075 yuan, about 200 yuan less than its official price.
Other models in China's grey market are priced only slightly higher than the official cost offered by Apple. One reason grey market dealers can offer a better deal on the iPhone 6 is because of a Chinese import duty on electronics.
Analysts expect Apple's newest smartphone will sell well in the Chinese market, especially among existing iPhone users who want to upgrade to a bigger screen. In a sign of the demand, JD.com, a top e-commerce site in the country, showed on Monday that over 9 million users had made a reservation to order an iPhone 6 or an iPhone 6 Plus when stock becomes available.
On Monday, December 30, 2013 an iOS 6.1.3, 6.1.4, 6.1.5 untethered jailbreak all iPhones, iPads and iPods was released by @iH8sn0w and @winocm. Its name is p0sixspwn. While many in the jailbreak community should be pleased — particularly those with the iPhone 3GS and other iDevices which don't support the latest iOS 7 jailbreak — it seems this iOS 6.1.3-6.1.5 jailbreak came at a high cost, as other exploits reportedly could have been used to produce the same result.
On Monday morning, Evad3rs team member and evasi0n7 creator Cyril Cattiaux aka @Pod2g posted a series of tweets with regard to how the new p0sixspwn jailbreak was created and released.
While the jailbreak community has been extremely torn by the events of the last week, and few know where to place their loyalty, this latest drama seems like just one more hit to those who simply want to enjoy the freedom jailbreaks provide to their iOS devices.
— pod2g (@pod2g) December 30, 2013
Throughout the evasi0n7 debacle, @pod2g has been the most vocal of the evad3rs team members, writing two public letters to the community to explain the situation that developed with TaiG while also taking responsibility for the damage done and working to rebuild the bridge that was burned with @Saurik. But this morning's tweets seemed to show some frustration with the on-going drama that runs even deeper than has been completely told. It seems in releasing their new jailbreak for iOS 6X, @iH8sn0w and @winocm burnt some incredibly valuable exploits which have been kept carefully by the jailbreak developers for use in research when new iOS devices and firmwares are released. The most unsettling part of all is that burning that exploit was not a necessity.
So what does all of today's drama mean for the jailbreak community? In speaking to @pod2g this morning, it seems the loss is not a small one.
In hearing this description, numerous questions came into my mind. What will happen in the future if Apple patches this exploit? Could it be used in a downgrade tool? If Apple doesn't patch the exploit will a 7.1 jailbreak be released? Both @pod2g and @comex were gracious enough to give me some comment on these points.
"They talked a lot of sh-- about us, but now they've burnt valuable stuff just for 6.1.x ... nobody looked at their jailbreak tool, but they burnt something allowing root on all devices without any effort. Something that jailbreakers were aware of for years now. Something that's usually the entry point for jailbreak research on new iOS versions and devices. Root code execution. Something that usually requires multiple exploits to achieve."
According to @comex, though the exploit burned is valuable, it does not completely negate the ability to create future jailbreaks. According to the former jailbreak developer, "it makes things more difficult, but not impossible."
"Implications are that it'll make life of jailbreakers even harder for future iOS jailbreak developments. And I suppose that we'll never find another root execution and injection exploit of this kind in the future. Basically, it allows files to be made available in the device file system (injection) and allows to execute code as root. For example, we could setup afc2 on new iOS versions to play with the file system and find vulnerabilities."
This exploit, along with some others, was the same one @chpwn used last fall when he produced the infamous iOS 6 failbreak, which prematurely raised the community's hopes. In seeing the value that this particular exploit holds, I asked Cyril if a downgrade tool was in the works, or if by chance, Apple doesn't patch the exploit in 7.1, would the evad3rs be releasing an iOS 7.1 jailbreak using it.
Here is how he replied.
As to a possible iOS 7.1 jailbreak, this was his response.
"A downgrade tool is a completely different story. It requires breaking the boot chain of trust."
To that he added,
"It depends on what Apple patches ... let's say we'd want to burn it for iOS 7.1, we would also need a unsigned code execution vulnerability, a kernel exploit, and a way to stick that at boot."
To emphasize just how valuable the exploit is, @pod2g takes his explanation a bit further.
"But even if we still had that injection and root stuff, not sure that we would release it, because of its value."
"A jailbreak is a whole chain of exploits ... that exploit of @comex's that we did not want to burn in evasi0n7 [would require] 5 vulnerabilities to do the same thing. That's why it is so valuable. The fact that Apple did not patched it in years also is important. It means that it is probably the last thing you'd like to burn when there's nothing remaining."
As a final question, I did ask Cyril what his thoughts were on why @winocm and @iH8sn0w would burn such valuable exploits in the iOS 6.1.3 - 6.1.5 p0sixpwn jailbreak released Monday. Was it truly spite?
To that there seems to be no answer. Cyril's only response was:
I have reached out to @winocm and @iH8sn0w for a response, but thus far have received no reply. If they submit a rebuttal, I will update this post. To download and install @winocm and @iH8sn0w's iOS 6.1.3 - 6.1.5 jailbreak, visit p0sixspwn.com
"Why? I dunno. Perhaps they were not aware it still works on newer versions."

At its special media event today, Apple announced the 4.7-inch iPhone 6 and the 5.5-inch iPhone 6 Plus. Apple is touting a "Retina HD Display" on both phones, as the 4.7-inch iPhone 6 features a 1334 x 750 display at 326 pixels-per-inch while the iPhone 6 Plus features a 1920 x 1080 display at 401 ppi. The iPhone 6 is said to have more than 1 million pixels, while the iPhone 6 Plus is said to have 2 million pixels.
“iPhone 6 and iPhone 6 Plus are the biggest advancements in iPhone history,” said Tim Cook, Apple’s CEO. “The iPhone is the most loved smartphone in the world with the highest customer satisfaction in the industry and we are making it much better in every way. Only Apple can combine the best hardware, software and services at this unprecedented level and we think customers are going to love it.”
The new models feature a number of hardware changes, including a chassis that is 6.9 mm thin for the iPhone 6 and 7.1 mm for the iPhone 6 Plus. Both models feature the next-generation 64-bit A8 chip, which features 2 billion transistors on a 20nm processor. The A8 delivers 25% faster CPU performance and is 13% smaller and 50% more energy efficient when compared to the A7. The device also comes with a next-generation M8 motion coprocessor which can now estimate distance and elevation changes with a new barometer.
Apple states that the iPhone 6 will get 50 hours of battery life for audio, 11 hours for video, 11 hours for WiFi browsing and 10 hours for LTE browsing. With its even bigger body, the iPhone 6 Plus will get 80 hours of battery life for audio, 14 hours for video, and 12 hours for Wi-Fi and LTE browsing. The iPhone 6 now also includes Voice Over LTE (VoLTE) technology, including 20 LTE band, as well as 802.11ac Wi-Fi, which delivers 3x faster Wi-Fi and support for Wi-Fi calling.
The iPhone 6 and iPhone 6 Plus also support a new camera system with a brand-new 8-megapixel sensor, along with a circular true tone flash. Apple is also touting "Focus Pixel" technology, which allows the lens to move in and out to better determine autofocus points. The camera also features next-gen tone mapping and noise reduction. Apple also says the camera is complimented by a new gyroscope and image stabilization built into the A8 processor. Exclusive to the iPhone 6 Plus is an optical image stabilization system.
As for video capabilities, both devices shoot in 1080p at 30fps and 60fps, along with 240fps slo-mo video, which is up from 120fps on the iPhone 5s. The front-facing FaceTime HD camera has also received a new sensor with a f2.2 aperture that lets in 81% more light. Users can also shoot single-shot HDR photos and take HDR video.
Both devices will launch on September 19 in the first wave of countries, with pre-orders starting on September 12. The iPhone 6 will be available in 16 GB, 64 GB, and 128 GB variants for $199, $299, and $399. The iPhone 6 Plus will be available in the same storage capacities for $299, $399, and $499, respectively. Both iPhone 6 models also come in the same Space Gray, Gold, and Silver variants. The iPhone 5c is now free on contract while the iPhone 5s will now be offered for $99
