Samsung developing flexible ‘rollable’ batteries

Posted by wicked October - 17 - 2014 - Friday Comments Off

Say what you want about Samsung, but these guys have invested a ton of what they earn in profits back into their in-house R&D – which is why they don’t rely so heavily on outside suppliers all that much. The Galaxy Note Edge is really a shining evidence of how they have furthered their in-house AMOLED technology. But Samsung won’t stop with display technology – it is reportedly investing much in flexible batteries, the kind you can use with action-type wearable devices.

Samsung is putting a lot of focus on the wearable market which is now a pretty competitive market after the gadgets launched this year, specifically at the recent IFA 2014 in Berlin. That is why they are investing in batteries that will accept curved form factors and roll-able devices. Imagine what that could contribute to the general lightness and flexibility of a device.

Recently, Samsung SDI unveiled their progress in this area during the ongoing InterBattery 2014 exhibition in Seoul, South Korea. Using its own materials and design, Samsung unveiled a battery that would still function even when rolled like a paper cup. Pretty nifty, if we may say so.


We can think of one startup project that might need this – the flexible Portal fitness tracker-slash-smartphone – but sadly, Samsung has put a 3-year development period for their flexible batteries. The Portal is due to debut next year. Samsung may need to realistically consider what products it will use the technology on, and if they can find the raw materials to mass produce such a technology.

Scientists create batteries that recharge incredibly fast

Posted by wicked October - 15 - 2014 - Wednesday Comments Off

One of the places that smartphone and tablet technology is rapidly evolving is in the batteries we use to power the devices. A larger battery is a nice thing, but batteries can only be so large before the portability of the device they are in is affected.

One way that scientists are working to improve battery technology is in how fast a battery can charge. If the battery can charge fast enough, it doesn’t have to be large to give smartphones longer runtime. A scientist from Nanyang Technological University has created a new high-tech battery that is capable of recharging to 70% capacity in only two minutes.

This battery tech could be a huge breakthrough not only for mobile devices, but also for other products such as electric vehicles. These next generation lithium-ion batteries are expected to survive 10,000 charging cycles, making them about 20 times more durable than current generation batteries.

Scientists at the university replaced traditional graphite used for the anode of a battery with a new gel material using titanium dioxide, a cheap and abundant material found in soil. The team developed a method to turn the normally spherical titanium dioxide particles into nanotubes that are able to speed up chemical reactions in a new battery, allowing for faster charging. There is no word on when this new battery tech might be commercialized.

Ampy charges your smartphone through your own kinetic energy

Posted by wicked October - 13 - 2014 - Monday Comments Off

Poor battery life is unfortunately still a concern for many smartphone owners, with some handsets unable to last a full day in the hands of a power user. Ampy, a new Kickstarter project, aims to solve this issue without the hassle of remembering to charge up your battery pack. Instead, it stores kinetic energy from your daily walking and exercise routines.

The little pack connects up to your smartphone like any other battery accessory, but generates its own store of power from your movements. Ampy’s 1000mAh cell can be charged up through walking, 10,000 steps is apparently quite average for a single day, a 30 minute run, or a hour long bike ride. From this exercise, Ampy can keep a typical smartphone powered up for 3 hours, a smartwatch for an extra 24 hours, and can keep a fitness tracker juiced up for 3 whole days. Not bad for something that you don’t have to connect to the mains, although you can still charge it from the wall via a micro-USB connection if you’re feeling lazy.

Ampy charging figures

Alongside the charging pack, Ampy comes with an app that tracks the calories you’ve burnt off and the power generated from your exercise. Ampy also offers a small accessories kit, which consists of an arm band, clip, and sleeve to keep the pack in place whilst you’re on the move.

In the future, Ampy hopes that its kinetic technology can be built into smartwatches and other wearables to help power them without the need to charge from a mains supply.

Ampy will cost $95 when it starts shipping next June. The Kickstarter project has already surpassed its funding goal of $100,000, but backers can still grab their Ampy at a slightly discounted price.

AMPY powers gadgets using movement

Posted by wicked October - 10 - 2014 - Friday Comments Off

One of the biggest challenges that mobile users face is keeping their gadgets charged up when they are out of the home or office all day and use their smartphone frequently. Often the only choice is to go with a battery case of some sort to keep things running. A new option has hit Kickstarter called AMPY.

AMPY is a device that promises to charge your smartphone using your movement. AMPY is a wearable device that harnesses movement as you walk around during the day and turns that movement into power to keep your smartphone or other gadget running.

AMPY also interfaces with an app that will keep track of stats for you like how much time you spent running or walking, and how many steps you took. It will charge any iPhone, Android device, or USB device.

Inside the small AMPY case is a lithium ion battery to charge devices. Power in that battery also stores your activity data for about a week. The project is seeking $100,000 and has raised over $52,000 as of writing. A pledge of $75 or more will get you an AMPY with shipping expected in June.

DROID TURBO may have 3,900mAh battery

Posted by wicked October - 10 - 2014 - Friday Comments Off


A new leak about the upcoming Motorola DROID TURBO for Verizon indicates the battery will be a massive 3,900mAh unit. This should provide plenty of battery life for the DROID TURBO. Last year’s DROID MAXX had a 3,500mAh battery and was one of the larger batteries on the market. Combined with a possible QHD display and 3GB of RAM, the DROID TURBO could find itself competing at the high end of the market.

The image came courtesy the TaoBao web site, an online retailer in China and was posted by Twitter user @owen199208211. The model number of the battery in the image is EQ40 which is the same model number listed in an FCC database entry filed earlier.

As with leaked information from unusual and only vaguely identified sources, the big question is whether the image is a fake or not. Hopefully we will know the answer before the end of the month as some think Verizon is ready to release the new DROID TURBO the last week of October.

Come comment on this article: DROID TURBO may have 3,900mAh battery

DROID TURBO Will Have a 3,900mAh Battery

Posted by Kellex October - 9 - 2014 - Thursday Comments Off

An image in a listing posted up at TaoBao, a Chinese shopping website like eBay or Amazon, just gave us the official size of the battery in the yet-be-announced-but-all-sorts-of-leaked DROID TURBO. We pointed out through an FCC listing that the battery in the device fell under model number EQ40, which we assumed meant it would be large like last year’s DROID MAXX, a device that used a 3,500mAh battery under the model number EU40.

Assuming this listing is correct and this is the EQ40 that will be featured in the DROID TURBO, you are looking at a device with a 3,900mAh battery. That, my friends, is huge. With a battery that size, you should have no trouble getting through two days of use. 

Couple that massive battery with its 5.2-inch UHD (or QHD?) display, 3GB RAM, 21MP camera, Moto suite of services, and (hopefully) mostly stock Android, and you may have the best DROID in years.

The DROID TURBO has not been announced yet, but sources of ours told us to expect it by October 30, with an announcement on the 28th or 29th.

Galaxy Note 4’s battery benchmarked, good results

Posted by wicked September - 29 - 2014 - Monday Comments Off

The Samsung Galaxy Note 4 already launched in its home market in Korea, so they are able to play around with the unit earlier than us. There are evidences that the new model will start hitting American shores by mid-October, so until then, we will have to be satisfied with benchmarks from Korea. This particular one is a battery test done with a Korean Galaxy Note 4 running an Exynos chipset.

Specifically this would be the Exynos 5433 octa-core chip, with a big.LITTLE architecture set of four 1.8Ghz Cortex A15 processors and four 1.4Ghz Cortex A7 processors. The battery tests had three iterations – first was a WiFi test with the phone’s stock browser being refreshed every 5 seconds. The second was a video playback test done by looping a 1080p .mkv on the Note 4’s default player. The last test was a graphics rendering test looping GLBenchmark 2.5’s Egypt HD C24Z16 test.


With all these tests, we could say that those planning to buy the Samsung Galaxy Note 4 with its monster 3,220mAh battery should be relatively pleased. The Note 4 lasted almost 12 hours on the video test at 100% brightness, a bit more when brightness was lowered to standard viewing settings. This places the new model in the top 5 devices with longest battery life in this test. The Note 4 also lasted 7 hours on the WiFi test at max brightness, and a full 1.5 hours longer on standard brightness – again placing the device in the top tier of devices that last longer on this test. On the graphics render loop, the Note 4 lasted 3 and a half hours – this drops the Note 4 to the middle of the pack or better, still a relatively good place for it to be.

We have to remember that the Note 4 has a gigantic screen, and with that it still performed really well. The Note 4 also has a higher max brightness level than the Note 3. The only other question would be if the quad-core Snapdragon 805 would perform just as great as the Exynos chipset seems to have done.

samsung galaxy s5 vs htc one m8 aa (15 of 19)

Recently we put together an infographic based on information we had collected from previous AA polls. The theme was whether or not the “spec war” was still as important as it once was. The vast majority said no, which falls in line with Motorola’s Rick Osterloh’s prediction that high-end, high-priced smartphones could eventually go the way of the dinosaur.

So if raw specs aren’t as important, what would we like to see improve instead? In our poll-based infographic an overwhelming 58% said battery life. We’ve also seen this sentiment expressed in various comment threads on our site, in our forums and across the web. In fact, whenever we report on a new handset attempting to claim the “thinnest ever” title, we usually see a number of comments saying that being thin isn’t as important as a good battery.

Of course, not everyone feels this way. Some folks are in their cars or homes a lot were they can constantly charge, others simply are willing to sacrifice battery life for thinness and perceived greater beauty. So how can OEMs appeal to both sides? The answer seems simple enough: create at least two different models for each major phone release, one that focuses on design and being thin, with another focusing on battery life even at the cost of a thicker body.

Honestly, this isn’t a novel concept, as we’ve seen Motorola offer up a “Maxx” version of its Droid family more than once, offering the same specs but with a much beefier battery. So what’s the downside here, and why aren’t more OEMs doing this? Other than potential added development and marketing costs (though probably minor), we can’t see too many downsides, though we admit we aren’t handset manufacturers so perhaps there is a bigger factor that we just don’t realize.

What do you think, would you like to see OEMs offer up a “Maxx” (or Plus, or BFB or whatever they want to call it…) variant for all major flagships, and even on some of their mid-rangers as well? How much of a premium would you be willing to pay over the standard ‘skinner’ model, if any?

Samsung Power Sharing cable lets you spread the love

Posted by wicked September - 24 - 2014 - Wednesday Comments Off

Have you ever suffered from battery envy? That’s when your friend or colleague still has his device fully charged or with high battery levels while yours is slowly petering out. Now if your friend is really nice, and you don’t have a power bank or any other way to charge your device, then Samsung’s newest accessory would come in handy. The Power Sharing cable lets you do exactly what its name suggests: share power between Samsung devices.

The accessory works simply enough: it shares power directly from one Samsung device to another that is needing a quick charge. So whether it’s a smartphone, tablet, Bluetooth headset or a wearable that’s needing a boost, you can now do so with the power of this cable. Not all devices however will be able to share their power. As of now, it’s just the following: Galaxy S 5, Galaxy Tab S 10.5, Galaxy Tab S 8.4, Galaxy Alpha, Galaxy Avant, and the Galaxy Note 4. But as to which can receive battery life, it’s actually any device that has a micro USB. So even non-Samsung devices can technically receive a power boost with this cable.


The cable has arrows to indicate which way the power will flow from one device to another. To be able to control the amount of power that you want to share, you need to download the Power Sharing app. It monitors the progress of the power sharing as well as the aforementioned option as to how much power your device should share. After all, you need to also ensure your device will not run out of juice.


You can download the app from the Google Play Store or the Samsung App Store. The Power Sharing cable is available for $19.99 through the Samsung online store, but may also be ordered through other online stores.

Pixel Battery Saver turns off pixels to save power

Posted by wicked September - 23 - 2014 - Tuesday Comments Off

There are times when we all want more life from the battery in our smartphone or tablet. An app called Pixel Battery Saver claims to be able to turn off pixels on your screen to reduce power consumption and make your battery last longer by overlaying a black mesh on the screen. The developer of the app says that some AMOLED screens on smartphones don’t work with the app, so your mileage may vary.

The app applies a black mesh look over the screen of the smartphone and the user can control the density of that mesh overlay. The quality of images on screen is reduced with the app active, but if all you need to do is check the time it might not matter. The app is offered in premium and free versions.

In the free version, the install button is disabled preventing the installation of other apps while Pixel Battery Saver is running. The developer says that is due to Android security and that in the premium version there is an option to get around that issue. The app was updated this month and the update brings a fix for a bug in the Navigation Bar Overlay.

Pixel Battery Saver is 2MB in size and is on version 1.3.2. The app requires Android 4.1 or higher and has been installed 1000-5000 times according to Google Play.
