Google squashes Android 5.0 Lollipop battery-drain bug

The bug was reported by developers with Nexus 5 smartphones but has been resolved just as the updated mobile operating system begins to trickle out.

A bug in Android 5.0 Lollipop was draining Nexus 5 smartphone batteries at a fast clip, but the Wi-Fi-related glitch was fixed by early Thursday.
Nexus 5 users who had received the Android 5.0 update had been complaining that their phone battery would drain much faster than expected when Wi-Fi was enabled. Users piping in on theAndroid Developer Preview site noted that an entry on their device's battery stats screen called "Miscellaneous" was sucking up a lot of juice.
On Wednesday, Google's Trevor Johns, a senior developer programs engineer for Android, confirmed the bug on the Android Developer Preview site:
Android Engineering is aware of an issue affecting Nexus 5 users running Android 5.0 which causes significant "Miscellaneous" battery usage while WiFi is enabled. This appears to be caused by an abnormally high number of IRQ wakeup events.
We are continuing to investigate this issue.
In a comment posted Thursday, Johns reported the resolution saying:
This issue has been fixed in the latest builds, and this issue is now considered resolved. Thanks everyone.
The battery-draining problem itself was ironic since one of the enhancements in Lollipop is a new battery-saving mode that slows down the CPU and turns off background data when your battery is running low. With the Wi-Fi-related glitch fixed, the rollout of Android 5.0 that began as a trickle this week for older Nexus devices should move forward as planned.

These smartphones have the best screens you can find

Beauty may be in the eye of the beholder, but everyone can agree that these smartphones have the most eye-watering displays around.




Editors' Note: This post was originally published September 25, 2012, and is updated continuously.
In addition to all the times we casually glance at our smartphones throughout the day, studies estimate that we spend more than an hour everyday staring into our handsets. That's an hour spent watching videos, playing games, and checking out photos.
manufacturers pour so much into display technology, and why screen size and brilliance It's no wonder why, then, smartphone 
are important to users when considering a high-end smartphone.
These days, stunning 1,080p and 1,440p displays can be found on many top-tier handsets. But CNET rounded up some of the best touchscreens that have come our way recently.
Not only do we take in factors like resolution and pixels per inch (ppi), but we consider brightness, vibrancy, viewing angles, and color tones as well. Take a look at these top-notch displays below and let us know what you think in the reader comments.

In addition to its sharp display, the Droid Turbo has a long-lasting 3,900mAh battery.James Martin/CNET

Motorola Droid Turbo

Equipped with a high-capacity battery, a Snapdragon 805 processor, and a 21-megapixel camera, the Droid Turbo already has the workings of a solid device. But add a crisp 5.2-inch touchscreen with 565ppi and you have one of the most premium handsets around.

According to CNET's Aloysius Low, the Find 7's screen is so sharp, you can barely make out any pixels, even when zoomed into the picture.Aloysius Low/CNET

Oppo Find 7

You might have never heard of the Find 7, but this smartphone from Chinese-based manufacturer Oppo has one of the most impressive displays we've seen. Packing 538ppi, it was one of the first globally available handsets with a 1,440p quad-HD panel.

LG G3

With its 2,560x1,440-pixel resolution and a barely-there bezel, the 5.5-inch G3 gets major bragging rights. And while those specs may not be that discernible against its flagship competitors, or even to the human eye (which is only able to see about 466ppi), there's no denying that LG's marquee device is one sharp smartphone.

Samsung Galaxy Note 4

Because the original Samsung Galaxy Note kicked off the era of big-screen smartphones, it's safe to expect every iteration after the first will sport a stunning and vivid display. The Note 4 is no exception, offering an expansive 5.7-inch quad-HD panel with a number of baked-in software goodies that work with the device's smart S Pen stylus.

Sony Xperia Z3

Having a 1,440p resolution isn't a requirement to land on this list. Case in point? The Xperia Z3. Its 1,080p display is punchy, sharp, and power efficient as well. Sony claims that compared to 2K screens, the Z3's is better for the battery. As such, the handset (which, we add, is also water-resistant) has a reported usage time of two days, and during our battery drain test for continuous video playback, it lasted an impressive 12.5 hours.

Google Nexus 6

Google dropped a big surprise when it announced its newest marquee handset would flaunt a huge 5.96-inch display. But whether or not the size is right for you, there's no denying it still has a great AMOLED screen. Featuring 493ppi, Android Lollipop 5.0, and a Snapdragon 805 CPU, the Nexus is one of the highest-end phablets on the market.

Samsung Galaxy S5

Though Samsung cranked up the resolution for its Korean Galaxy S5 variant (in fact, it has an envelope-pushing 576ppi), the company still improved on its original Galaxy S5's 1080p screen. For one, it's equipped with a useful display panel and accompanying technology, which helps it to adapt to different lighting environments. The over-saturated tones that often plague AMOLED screen have also been toned down, leaving colors more realistic, but still striking. 

Mozilla makes Firefox for iOS a priority again

In a major reversal, Firefox's leader tells Mozilla community members he wants the open-source browser on Apple's mobile devices. A better mobile presence is key for Firefox's future.

Mozilla apparently is trying anew to gain a browser foothold on iOS, the operating system that powers Apple's iPhones and iPads.

Johnathan Nightingale, vice president of Firefox at Mozilla, told Mozilla community members about the idea on Tuesday at the non-profit organization's Mozlandia event in Portland, according to Twitter accounts from several at the meeting.

"We need to be where our users are so we're going to get Firefox on iOS," Mozilla Release Manager Lukas Blakk said, apparently giving an account of Nightingale's speech, in a tweet that TechCrunch spotted.

Matthew Ruttley, Mozilla's manager of data science, added, "Firefox for iOS!! Let's do this!!!" in the tweet pictured above. Other Mozilla community members at the event chimed in with their own accounts of the news, quoting Nightingale and Mozilla President Li Gong.

The move is a change of strategic direction for Mozilla -- one among several as the non-profit organization tries new ways to retain its influence in the face of new challenges. Those challenges include the climbing popularity of Google's Chrome browser and Firefox's faint presence in the smartphone and tablet market, where people spend more and more of their computing lives. A decade ago, Mozilla's mission was to break the dominance of Microsoft's Internet Explorer, but now its top priority is to bring openness to what the organization sees as the "jails" of iOS and Android.

In 2012, Mozilla showed a browser for iOS called Junior, but the effort ultimately didn't bear fruit. In 2013, Mozilla said it wouldn't build Firefox for iOS because of objections to the limits Apple places on third-party browsers.

Mozilla confirmed the work in a brief statement, calling it experimental but declining to reveal further details.

"We are in the early stages of experimenting with something that allows iOS users to be able to choose a Firefox-like experience," Mozilla said. "We work in the open at Mozilla and are just starting to experiment, so we'll update you when we have more to share."

Diminishing share of usage

A better presence on smartphones and tablets is crucial for Mozilla's effort to remain relevant in today's computing world.

Firefox remains a significant force on the Web and in charting standards that make the Web a more viable competitor to iOS, Android, Windows and OS X. But its share of usage is slipping. As a share of desktop and mobile browsing, Firefox has slipped to 11.6 percent of usage, according to figures from analytics firm StatCounter. On tablets and smartphones, its share of usage was just 0.5 percent in November.

For Firefox, Google no longer is the global default search engine.

Mozilla has branched out to mobile with a version of Firefox for Google's Android OS and with its own Firefox OS in lower-end smartphones, but Firefox for iOS is different. That's because Apple doesn't permit others' browser engines on its mobile OS. Instead, third-party browsers, such as Google' Chrome and Opera's Coast, must use an Apple-supplied engine.

For Mozilla, that's been a big sticking point, because it undercuts the organization's mission to use Firefox to encourage the use of open Web technologies instead of technologies locked to one company's computing platform.

For example, Apple's browser engines don't support the WebRTC technology for real-time communications on the Web. WebRTC is core to Firefox's Hello service for online chat, which competes directly with Apple's FaceTime.

Apple's boost to others' browsers

With iOS 8, though, Apple has improved conditions for third-party browser makers. The browser engine it supplies for the purpose now is significantly faster at running Web-based JavaScript programs, meaning that third-party browsers on iOS can better match Safari's own performance.

The move was made in response to requests from programmers writing iOS programs, Apple said in June at its developer conference. Releasing a version of Firefox for iOS might not be everything Mozilla could want, but it might give the organization more influence with Apple than it has on the iOS sidelines.

There's also room for some customization on top of Apple's browser engine core. Browser makers can customize user interfaces, support new network software like Google's SPDY, set search engine defaults, and synchronize people's browsing history and bookmarks.

Two other big changes are the shift away from Google as Firefox's global default service for fulfilling searches through the browser -- Mozilla has just begun switching to Yahoo as the default in the US -- and the presentation of advertisements on Firefox's new-tab page. One early ad Mozilla showed was for "Citizenfour," a documentary film about former NSA contractor Edward Snowden, who leaked information about intelligence services' online surveillance activities.
