Do you want to buy an iPad 3?

CloudTags: iPad 3, iPad HD, battery , battery life , laptop batteries ,

In two days Tim Cook will take the stage to announce the iPad 3 or iPad HD, the Apple tablet we’ve anticipated for quite a while.

Leading up to the announcement PriceGrabbersurveyed 1,829 of its users to find out what features they want in the iPad 3.

You might be surprised to find out what nearly half of the respondents want from the iPad 3.

Of those surveyed 42 percent of iPad owners planned on upgrading to the iPad 3.

Most of these upgraders plan to buy the new iPad before the end of 2012, but 11% want the iPad 3 during the first week. With A Retina Display, better camera and upgraded processor, it make sense that many current iPad owners want to upgrade.

The number of upgrading iPad owners isn’t surprising, but the features that survey respondents want from the new iPad are.

Over half of the respondents said they want a cheaper iPad 3, but that’s not all.

53% want longer battery life from the iPad 3. That’s surprising because the iPad 2 delivers 10 hours of use.

In the real world, the iPad 2 can easily last an entire day unless you are playing games like Infinity Blade II non-stop. While the iPad 3 will likely have a better battery, the new Retina Display and processor are expected to use more power, resulting in a battery life that doesn’t change much.

The rest of the survey’s results are:

49% indicated SD card to store data
44% indicated better camera with flash
44% indicated new A6 processor
41% indicated built-in HDMI port
36% indicated wireless synchronization facility

Those results are pretty easy to comment on. The SD card slot and HDMI port won’t happen anytime soon, though Apple does have adapters for both. The camera hole on the back of the iPad 3 seems to be larger, which should mean a better camera, but there’s no hole for a flash. It seems that only the iPhone gets a camera with a flash.

The new A6 processor seems likely, unless it’s an A5X chip. But either way, there will be a better CPU.

And, oddly enough, wireless sync, which already exists for the iPad, garnered 36 percent.

Are you planning on buying an iPad 3 when it goes on sale? If so, is battery life the most important deciding point for you? Let us know in the comments below.

How does Windows 8 fare? Battery life test

CloudTags: battery , battery life , laptops，laptop batteries , Samsung NC 10

Tablets and Ultrabooks are on the rise and Windows-on-ARM (WOA) tablets are on the horizon. For Windows 8 to succeed in today’s — and tomorrow’s — market for both low- and high-powered portable devices, Microsoft needed to get rid of its “fat” Windows without losing functionality. The goal was to not just increase responsiveness, but also to improve battery life, which is obviously one of the core criteria for everyone shopping for a new laptop or tablet. How does Windows 8 fare? We’ve got answers”:

Microsoft’s promise: Less energy consumption

Redmond pushed out almost a dozen blog posts that either demonstrate their battery life/power consumption improvements or show off how new their new features (e.g. USB 3.0 support, Connected Standby, Live Tiles, Metro Apps) are built with saving power in mind.

Here are the highlights:

All background Metro-style apps will be suspended; only the foreground app consumes resources and thus battery life. If an app is not on screen and actively used, it shouldn’t drain battery. Only a set of apps will be allowed to use background activity (e.g. for music playback or printing).

Improved idle usage of the OS.
On-system drivers, such as the USB host controllers and keyboard drivers, put the device into low-powered modes sooner.
Memory deduplication mechanisms to reduce RAM workload.

Battery life benchmark: Windows 8 consumer preview

“We think of power as a critical system resource, just like CPU utilization, hard disk activity, or memory consumption.” explains Pat Stemen, a Program Manager on the Windows Kernel team, on the B8 blog.

So how power-friendly is the new Windows exactly? We wanted to put Windows 8 CP up for a test run on a variety of laptops and see how it stacks up against Windows 7 SP1. Here’s the hardware I used:

Laptop A — Acer Aspire 7551G. A Run of the mill 17-inch laptop with a Phenom II X4 CPU and 4 GB of RAM. Good for multimedia, but not particularly well-suited in the battery life department.

Lapotp B — Samsung NC 10. One of the better 2008-era netbooks. The usual yada-yada specs (Atom N270 1.6 GHz, 1 GB RAM). Low performance, extremely good battery life.

Laptop C — 13″ MacBook Air (2011) equipped with a 1.8 GHz Core i7, 4 GB of RAM and a 256 GB SSD drive.

* I didn’t test on an ultrabook, but the MacBook Air running Windows matches the most current ultrabooks in terms of specs, battery power and form factor.

All three represent very different laptops, targeted at very different audiences. Evaluating these devices should give a good glimpse of what to expect on the battery life front.

Test scenario

I used PCMark 7′s “Lightweight” test, which simulates typical workloads such as adding music to Media Player, browsing the web, copying files and scanning for malware while leaving a couple of seconds of idle time in between. I looped the test until the battery of the device ran dry. Second, I just let the laptop sit there, do nothing and just “die”. While that’s not a particular realistic scenario, it demonstrates idle usage which is very important for battery life: Remember, you’re not constantly pushing your CPU to its limit — while you’re reading something, sitting in a meeting or just waiting in between presentation slides, your laptop needs to go into idle as fast as possible and stay there until you do something. It is a good basis for judging power management.

Since third party software usually impacts battery life, I installed only the very basic programs such as Office 2010, TeamViewer, SnagIT, Adobe Reader and Flash on both machines. In all cases, I used the “Balanced” power saver mode and cranked up brightness to about 50-70%, while leaving Wi-Fi on.

Results

I repeated each test run exactly three times to avoid discrepancies. In each and every case I got pretty much same results (+/- 5 minutes). Results are measured in minutes:

Microsoft has done its homework. Idle performance of Windows 8 seems to best that of Windows 7 SP1 in every case. This is especially true on the MacBook Air: Here, idle battery life increased by 51 minutes. Even under the PCMark 7 workload, it managed to squeeze 24 minutes of additional battery life out of the machine. Our trusty old Samsung NC 10 ran for 40 more minutes in “idle” while it gave me another 20 minutes under typical workload. While that’s not a lot, it may just mean the difference between wrapping up a movie or work on an airplane and having to stare at a blank screen for the rest of the flight.

Overall: While there are no major leaps, these are all solid improvements across the board.

Apple iPad in man s hand jpg 300x168 5 Things Journalists Ought to Know About Tablets Journalists and photographers need to rethink how they package – and how they get paid for – their work when it comes to tablet computers. Tablets, predicted to become the reading device of choice in the next few years, will change the demand and market for information.

Those are some of the takeaways from a “Hacks and Hackers” meetup held at Storify headquarters in San Francisco called, “New rules of storytelling: The rise of tablets.”

Talking about the burgeoning demand for touchscreen-friendly information were John Knight, a co-founder and editor of Closed Mondays, whose recent tablet projects include Al Gore’s “Our Choice” and Tim Ferriss’s “4-Hour Chef.”

Here are five more points worth touching on for journalists and photographers when it comes to tablet publishing.

1. There’s No Money in Tablet Publishing – Yet

Once Magazine, launched in September, has a revenue sharing model that will hopefully pay journalists and photographers decent rates for their work. Readers currently pay $2.99 for each edition. When answering a question from the audience about whether tablet publishing provides a decent paycheck, Once‘s Knight said, “No! Just kidding. Sometimes. Well, it could… If we have 20,000 subscribers, it would be decent paycheck. I mean, if we could pay $2,500 for the photos and $1 a word, that would be decent. First, you have to establish yourself. The onus right now is on contributors to market… There’s not a market for us right now any more than there is for contributors.”

2. Your News Organization Is Interested in Them

Back in January, Forrester research predicted that U.S. consumers would buy more tablets than computers by 2015.

In addition to launching hundreds of dedicated apps, news organizations have heeded the call to create content consumable on tablet computers with initiatives ranging from Rupert Murdoch’s iPad-only publication The Dailyto a Philadelphia media group subsidizing tablets for readers. The result? The Economist recently reached100,000 subscribers for its iPad version.

3. Tablet Publishing Isn’t Necessarily About Interactivity or Extreme Stories

Once‘s format doesn’t allow readers to pinch and zoom on photos, for example. “That’s how it was shot and this is how you look at it,” Knight said. He added that the photos are carefully chosen and crafted, and that the reader isn’t the professional, plus it’s more work for the publisher. One of Once‘s more popular stories, Knight said, isn’t “war photography, but a story about a retirement community in Arizona.” The photos chronicle the daily activities of the over-55 members from gymnastics to crocheting.

4. Tablet Publishing May Reverse the Traditional Text-to-Photo Ratio

Once magazine publishes three stories per edition, each story contains 15-20 photos accompanied by 800 words of text, the opposite of your usual word-heavy glossy magazine where two or three pics accompany 10,000 words of copy.

5. Get Ready for the “Bookification” of Content

Rymill’s latest project is the “4-hour Chef,” specifically made for the Kindle Fire. The free app, designed for first-time tablet users, gives a “taste” of the forthcoming Tim Ferriss book of the same title. Launched right after Thanksgiving, it’s a combo cookbook, diet and exercise regime that promises to get readers into fighting shape before the expansive Christmas holidays.

using cellphone New Phone Batteries Technology Promises Charge 10 Times Faster and Longer Life

They’ve created an electrode for lithium-ion batteries that allows the batteries to hold a charge up to 10 times greater than current technology and charge 10 times faster.

As well as better batteries for cellphones and iPods, the technology could lead to more efficient, smaller batteries for electric cars, says the team. The technology could hit the market in the next three to five years.

With current technology, the performance of a lithium-ion battery is limited. How long a battery can maintain its chargeis limited by how many lithium ions can be packed into the anode or cathode. Meanwhile, the speed at which it recharges is limited by the speed at which the lithium ions can make their way from the electrolyte into the anode.

Kung’s research team has been able to stabilize the silicon in order to maintain maximum charge capacity, by sandwiching clusters of silicon between the graphene sheets. This allows for a greater number of lithium atoms in the electrode while utilizing the flexibility of graphene sheets to accommodate the volume changes of silicon during use.

Tips To Make Your Cell Phone Battery Last Longer

Most phones now days don’t need the backlight to view the screen, so it might be wise to leave the backlight off.
Regardless of how well you care for your battery, it will die eventually. When it does, you may be able to have it refurbished by sending it to the manufacturer or bringing it back to the retailer. If it cannot be refurbished, or if you just want to get a new battery, be sure to recycle it, either by returning it to the manufacturer or retailer, or by bringing it to a recycling center. Most major retail electronics stores have drop-off boxes for recycled phones.
Check to see if your phone has a “Battery Save” option. If so, you can turn this on to increase the life of your battery.
You should not have to turn off your phone to charge it. Most battery chargers deliver more than enough current to power your phone and charge it at the same time. Doing so will not lengthen the charge time, and leaving a phone on allows the user to be aware of its fuel gauge, so that you can remove it when the battery is full.
When using a car charger, do not charge the battery when the inside temperature of your car is hot. Wait until the car has cooled before you plug in the phone.
Nickel Metal Hydride (NiMH) batteries naturally get quite warm while charging, unless you use a specialized “slow charger”. If your phone uses a NiMH battery, do not worry about the heat generated during charging unless it becomes so hot that it is uncomfortable to touch.
mAh is an abbreviation for milli-ampere hours which are units of electrical charge. Larger values, for batteries of the same battery voltage, indicate that the battery has a larger capacity and will power your phone for a longer period of time before charging.
There are numerous battery retailers and discounters that will answer questions you have regarding prolonging the life of your cell phone battery.
If your phone is connected to your email, make sure it’s not set to check your email every 15 minutes or half an hour. This means that every time it checks, you lose a little battery. Set it to where it doesn’t check automatically, and you’ll save a lot of battery this way.

Looking to buy a new laptop for Your Student? Our list of priorities will help you find just the right one.

laptop school1 Student Laptop Guide: What You Need, What You Don’t Your laptop is hopelessly outdated. Maybe you’re accustomed to using the family computer at home, and will need one of your own as you head off to college. Or perhaps you’re a high school student who just can’t take another year of sharing your computer with relatives. Whether you’re a parent purchasing for your child or a student spending your own limited funds, you should look for a few key things when buying a laptop for academic life. With our list of what to consider and what to avoid, the dizzying array of choices just might seem less overwhelming.

What You Need

1. Long Battery Life

If you’re a college student, you’ll be carrying this thing around all day, taking notes in class and finishing up assignments at the last minute. A 4-hour battery won’t cut it.

2. Low Weight

hp pavilion dm1 783550 g1 5183846 Student Laptop Guide: What You Need, What You Don’t

Your bag will be heavy enough with all those books in it. Although an extra pound or two doen’t seem to make a big difference at first, it adds up quickly. Look for something under 4 pounds–your shoulders will thank you.

3. Good Keyboard

lenovo thinkpad x220 823936 g1 5183850 Student Laptop Guide: What You Need, What You Don’t

You’ll do a lot of typing on this machine. It isn’t just about writing papers, either: Online chat, Facebook, Twitter…95 percent of what you’ll be using this laptop for involves more typing than anything else. Find a laptop on which you can type quickly, comfortably, and accurately.

4. High-Definition, Low-Light Webcam

For video chat, duh! It’s fun with your friends–and if you’re off at college, your parents will appreciate the ability to see your smiling, hung-over face every now and again. Nearly every laptop has a built-in webcam, but not all are created equal. Look for a high-def webcam that works well in low light.

5. Warranty or Protection Plan

We don’t often recommend extended coverage plans for technology, but students are notoriously rough on laptops. Notebooks get tossed into bags and dropped, accidentally kicked by clueless roommates, spilled on by clumsy classmates, you name it. Choosing a durable laptop is a good start, but make sure that you aren’t without your second-most-critical piece of technology (next to your phone) the day before a big assignment is due.

6. Security Software

Laptops are stolen all the time at schools, even from students who are really careful. Look into software that will help you recover a missing laptop and keep your private information safe, such as GadgetTrack, Hidden, or LoJack. You definitely want to run a good antivirus program, such as Avast or Microsoft Security Essentials, as well.

How Today’s Students Use Technology

What You Don’t Need 1. Quad-Core Processor

There’s nothing wrong with a quad-core processor; for most of what a student uses a laptop for, however, two cores is plenty. A dual-core CPU typically uses less power and costs less, while providing plenty of performance for writing, researching, goofing off online, and editing photos.

2. Powerful Discrete Graphics

A good graphics chip is useful for a lot of things, from better video quality to faster web browsing. A powerful discrete graphics chip is practically mandatory for playing modern top-shelf 3D games, too. Unfortunately, they come with a bunch of drawbacks: They generate heat, they eat through your battery, they make the system bigger and heavier, and of course they cost more. Stick with a high-quality integrated graphics offering (such as AMD’s) or a modest discrete graphics chip.

3. Solid-State Drive

SSDs are a lot faster than traditional hard drives, and arguably more durable. They also offer a lot less capacity and can add hundreds of dollars to the cost of a laptop. We love SSDs, but the typical college or high school student doesn’t need one. A student needs the capacity to hold lots of music, videos, and photos in a laptop that’s affordable enough not to bankrupt you if it has to be replaced.

4. Touchscreen microsoft touchscreen surface at and t store5 300x200 Student Laptop Guide: What You Need, What You Don’t

Touch is all the rage these days, and it’s even popping up on a few laptops. But laptop software optimized for touch isn’t commonly available yet. A touchscreen is a costly–and mostly useless–feature on a laptop right now, especially for budget-conscious students. Maybe Windows 8 will change all that next year. For the time being, however, save the touchscreens for your phones or tablets.

5. 4G Wireless

A 3G cellular modem dongle can be a good way to obtain emergency Internet access when you can’t get on Wi-Fi, but a student certainly doesn’t need WiMax or LTE. Access plans cost enough already without the extra amount for 4G speed. Students taking a break from homework can wait to watch a YouTube clip or Netflix movie until they get back on Wi-Fi.
