Charger that can charge your phone in just 15 minutes
A charger that can charge your smartphone phone in just 15 minutes has been developed by the researchers. It is an external phone charger. It has been named ‘Petalite Flux battery’. It can charge your smartphone from empty to full in just 15 minutes. It will be launched at the end of the August during the Indiegogo crowd funding.
Development of charger:
Originally this charger was developed by a graduate from the Aston University named Leigh Purnell. The Petalite Flux battery is small enough to fit in your pocket or bag and you don’t even need to plug your phone into electricity socket or computer USB slot.Where to get:
You can per-order the Petalite Flux battery at www.petalite.co.ukAccording to a recent survey, 92% of British people feel tensed if battery of their smartphones runs out. So, to cover up the problem Purnell decided to create the world’s fastest charging external battery. Thus, he established Petalite Battery Systems in 2014.
Leigh is a Technology and Enterprise Management graduate. He said” I founded Petalite Battery Systems to permanently remove the stress and worry of having a mobile phone on low battery when you are out and about. It is an increasingly large problem in modern life, especially if you are relying on your phone to direct you somewhere or are waiting for important information to be sent to you."
Also, UNU Electronics has developed a new Ultrapak Portable Battery Pack Series. This device can charge-up your smartphone sufficiently in 15 minutes to be able to recharge most smartphones completely.
The battery pack is available in two variants: Ultrapak Go and the Ultrapak Tour for $59.99 and $99.99 respectively. The Ultrapak Go has a 3000mAh battery capacity that can fully charge in 30 minutes, while the Ultrapak Tour has a 10000mAh large battery capacity that takes 100 minutes to charge fully.
Charger like these will change the way we use our phone and take off the stress to charge our phone regularly.
Internet connectivity to battery-less devices
Internet connectivity to battery-less devices!?
Soon we will be able to connect to the internet without using any batteries in their devices.A new communication system in which radio signals are used as power source and which then reuses existing WI-Fi infrastructure to provide internet connectivity to the battery-less devices.This way communication was termed as 'Wi-Fi' back scatter.It was bought up by the engineers from the University of Washington.According to the engineers, this technology will play a major role in the concept of 'Internet of things'.
About:
As said by Mr.Shyam Gollakota, a University of Washington assistant
professor of computer science and engineering,"If Internet of Things devices are going to take off, we must
provide connectivity to the potentially billions of battery-free devices that
will be embedded in everyday objects,”He also added “We now have the ability to
enable Wi-Fi connectivity for devices while consuming orders of magnitude less
power than what Wi-Fi typically requires.”
This new way of communication will be soon published at the he Association
for Computing Machinery’s Special Interest Group on Data Communication‘s annual
conference this month in Chicago. The team behind 'Wi-Fi' back scatter technology plans to
set up a start up company on the same very soon.
Research and Development:
Wi-Fi back scatter is based on old research according to which low powered devices such as wearable devices or temperature sensors had the capability to run without batteries or cords.This was possible with the help of radio signals in the air.The new research has taken this old research to the next level by providing these devices with internet connectivity.
Challenges:
This technique had to face a set of challenges as providing Wi-Fi connectivity was not an easy task since it required a lot of power consumption.The engineers build an ultra-low power tag prototype that also consisted of an antenna and circuitry that helped Wi-Fi enabled devices to consume less power.Actually Wi-Fi signals moving between the router and the smartphone are looked by these tags.
This Wi-Fi back scatter can provide communication with a Wi-Fi device at a rate of 1kbps with about 2 meters of distance between the devices.The researchers are planning to extend the range to about 20 meters.They will also have patents filed on the technology.
Co-author Joshua Smith, a University of Washington associate professor
of computer science and engineering and of electrical engineering said, “You might think, how could this possibly work when you have
a low-power device making such a tiny change in the wireless signal? But the
point is, if you’re looking for specific patterns, you can find it among all
the other Wi-Fi reflections in an environment."
Thanks to back scatter, soon we will be able to access internet with the help of a wrist watch or any such wearable devices and that also without batteries!
If
Internet of Things devices are going to take off, we must provide
connectivity to the potentially billions of battery-free devices that
will be embedded in everyday objects,” said Shyam Gollakota, a UW
assistant professor of computer science and engineering. “We now have
the ability to enable Wi-Fi connectivity for devices while consuming
orders of magnitude less power than what Wi-Fi typically requires.” -

Charge your smartphones with water droplets
You will soon be able to charge your smartphone with water droplets. According to some scientists, water droplets can be harnessed electricity which in turn can be used to power electronic devices.
Researchers at MIT (Massachusetts Institute of Technology) have discovered that humidity in air can be used to power your smartphone or laptop. According to them, water droplets jumping from a highly repelling surface can be used to power electronic devices.
It was discovered that water droplets spontaneously jumped away from super hydrophobic surfaces during condensation. Then it gained electric charge in the process. The research team has demonstrated that this process might be used to power electronic devices as this process generates small amounts of electricity.
In a press release MIT explained its discoveries: “Last year, MIT researchers discovered that when water droplets spontaneously jump away from super hydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices.”
According to the report, “super hydrophobic surface” with silica based nano-coatings can repel water. This technology can be used to charge your electronic devices. Apart from this it can also be used to produce clean water and generate power.
MIT also reported that this process can also be used to generate power simply by giving the second plate a hydrophilic surface. As the droplets jump, they carry charge from one plate to the other. If the two plates are connected through an external circuit, that charge difference can be harnessed by power.
Nenand Milijkovic, MITs post-doctoral fellow stated that what we need to do is to create a relationship between water present in the air (humidity) and a source of power and energy.
Milijkovic told MIT that water will condense out in the atmosphere, which is a natural phenomenon.
“The atmosphere is a huge source of power and all you need is a temperature difference between the air and the device.”
Google to launch $100 Android One during Diwali
According to reports, Google has planned to launch its first Android One smartphone in October this year in India.
Google announced about the Android One platform at the Google I/O conference. Under this platform, Google decided to bring out affordable smartphones into the market. These smartphones will cost around $100.
India and Indonesia have emerging markets for such affordable phones. Google expects to reach around 5 billion people through Android One devices in these markets.
The Android One handsets will be directly updated by Google (which is similar to the Google Play editions and Nexus smartphones).Hardware and software reference points will also be given in these smartphones. Also, the manufacturers will be able to install their own apps in these devices.
Micromax will be the first Android One device which will be priced $100 as mentioned by Google before. Sources say that it will be exclusively launched on Flipkart. This handset will have 4.5 inch display screen, dual SIM capability, integrated FM radio, and expandable memory. According to Pichai, at the Google I/O conference, Android One smartphones will come with Play Auto Installs. This app tells uses which apps are recommended for a smartphone.
Google is working with chip maker company MediaTek for its new Android One platform. The companies have been discussing about this in the last six months.
Google has also tied up with domestic handset manufacturers like Karbonn, Spice, Intex and Celkon to launch the smartphones.
Google has planned to invest Rs. 100 Crores on marketing and advertising on the android one program in India. It also plans to launch Android One devices around the festival of Diwali. Sundar Pichai, Google’s senior VP in charge of android, chrome and apps is expected to visit India for this program; further details would be available after his visit.

Nokia X Android Devices Will Run Windows Phone
There is bad news for Nokia fans who want Android on Nokia Smartphone because Microsoft is going to shift fron Android to Windows Platform.
Microsoft is going to shutdown Android for its Nokia X series smartphones announced by company's CEO Satya Nadella. This is the major changing step taking by Satya after being acquiring NOKIA this year.He also said X2 never had a chance, it is as good as dead.
Microsoft is going to shift NOKIA X from Android Platform to Windows Platform. Its expected that it might be follw the path of Lumia Devices.
Nokia has cooked Android back in February this year to create a new platform for its own smartphones. Nokia launches two Android smartphones this year under the Nokia X series. These two smartphones perform well in market and users give positive feedback. These phones lies between Series 40 based lo-cost Asha series and its Lumia Windows phones in pricing-wise.
Today’s announcement shouldn’t come as a surprise. Those following along saw the Nokia X line as a non-starter for Microsoft. Supporting the Android ecosystem simply didn’t align with Microsoft’s vision — even if the X line was designed for low-cost, developing regions. As Darrell stated in February, if you want Android on a Nokia phone, the X2 is your last chance.
Yesterday's announcement by Staya Nadella was quite surprising. Along with the discontinuation of Nokia X series Nadella also announces the 18,000 job cuts from Microsoft which include 12,000 jobs from Nokia. Microsoft also going to merge Nokia workforce to Microsoft. So if you want Android on Nokia, Nokia X2 is your last chance.

Microsoft smartphones with 1 week of battery life!
Microsoft is looking to change the idea of having to charge
our smart devices multiple times a day as the company believes that battery
technology is usually ignored unlike other components.
The software giant has put forward an idea of making
innovations in battery tech so that smartphones and tablets are able to deliver
a full week of charge. Microsoft's Senior Researcher in the Mobility &
Networking Research Group at Microsoft Research, Ranveer Chandra amazed
everyone with the idea at MIT Technology Review's Digital Summit in San
Francisco.
Mr. Chandra said that current devices are forcing users to
charge these devices every night while some unfortunate users have to charge
their smartphones multiple times a day. He says that Microsoft aims to change
that as it is looking to change the way how smart devices use power. As
smartphones and tablets are becoming more powerful, battery technology has
majorly stayed untouched.This has to be tackled.
As told by Chandra,one of the ideas that Microsoft is
working on at the summit is the one in which two smaller batteries would be
used in a device instead of a single large one. While one battery handles
powerful processes such as gaming, the other would power the phone with enough
juice to manage the background processes when idle. Such prototypes have been
reported to increase battery life by 20 to 50 percent.
Microsoft is also working on a project called E-Loupe which
monitors resource-demanding apps, slowing them down when the program predicts
that it is appropriate to do so. The research team at Microsoft is also working
on tool for developers which will help them predict how much power-hungry their
apps are. This can help them optimize their apps accordingly which would
enhance battery life on devices.
Even though the 1-week battery backup idea seems quite
unlikely for now, LG has already shown tremendous improvement in optimizing
battery usage in its devices like LG G2 and G3. Smartphone like the LG G3 was
expected to kill battery life due to its huge 5.5-inch Quad HD display. But the
Korean company surprised everyone with the battery performance on its flagship
smartphone by introducing a new technology called 3A and according to tests at PhoneArena, it has delivered.
The "A" in the name of this technology means
"Adaptive" while the number "3" signifies the number of
functions in the technology such as adaptive frame rate, adaptive clocking and
adaptive timing control. Experts believe that this technology helps LG G3's battery
last as long as a device with 1080p display resolution.
How LG has succeeded in this technology is dropping
framerate to 30fps whenever the activity on the smartphone's display is none.
The adaptive clocking and timing control affect the processor by under-clocking
it whenever the full use of the processor is not needed.
We could have seen better results if LG had used such
technology in the previous flagship smartphone like LG G2 which features a Full
HD display.
Hopefully Microsoft will also be able to come out with such
technology soon so that our smartphones can give similar battery performances
as mobile phones used to when they weren't "smart".
Android 5.0 to be announced by Google soon
Release date of Android 5.0 is yet to be
announced by Google,but it is most likely that the company will release it at
the I/O 2014 conference and might name it Lollipop
(though the name is not official yet).
At present, all the devices in the Google Play Store have their
clocks set at 4:40 which points to the current version of KitKat. Two weeks time
is remaining for the Google I/O
conference, so it could mean that we will witness the release of Android 5.0 at
the end of this month. Other important announcements expected at the Google I/O
includes Android TV and might also focus on the Android Wear.
In the past, Google has used the following clock times for its
various Android releases in the past:
Gingerbread (Nexus S): 2:30
Honeycomb (Moto XOOM): 3:00
Icecream Sandwich (Galaxy Nexus): 4:00
KitKat (Nexus 5): 4:4
Honeycomb (Moto XOOM): 3:00
Icecream Sandwich (Galaxy Nexus): 4:00
KitKat (Nexus 5): 4:4
Everyone’s waiting for timing this year.
Issue of some non-functioning non-working Moto G smartphone resolved
Over the
last couple of days, the issue of some non-working Moto G smartphones was discovered.
Motorola Mobility said it has resolved this issue and apologized for what it
called was a “one-off error”. Motorola’s retail partner Flipkart offered a
monetary credit and a full refund if a customer wished to replace the faulty
handsets.
Motorola
(US based smartphone maker) had informed customers over the last two days that
some of its best-selling Moto G handsets shipped into India did not have
registered and verified International Mobile Equipment Identity (IMEI) numbers,
which rendered the devices useless. An IMEI is a 15-digit unique code that
helps cellular networks to identify valid phones. It is the unique identity
number of each device, which is used to track it when stolen or misplaced.
The devices
with IMEI numbers beginning from 3533 and that with 16 GB memory versions were most
likely facing connectivity issues. This came out when Motorola communicated with
some of its customers who were facing problems. "This particular issue is
now resolved and the affected Moto G devices have been registered with all
network operators. All impacted customers can activate their phones
immediately," a Motorola Mobility spokesperson said on Wednesday.
Motorola
said that as a goodwill gesture to those affected,the popular e-commerce
website Flipkart - the handset maker's exclusive retail partner - has credited
Rs 1200 into Flipkart wallets or accounts of impacted customers for any
purchase. That apart, Motorola has offered to replace the faulty handset or
fully refund customers who did not wish to wait for a replacement.These steps
were taken as an apology for the glitch.
The
number of complaints received or the number of devices that were replaced or
cases in which it refunded customer’s money were not revealed by neither
Motorola and Flipkart. India is
the most critical geography for Motorola, where the smartphone market continues
to be one of the top growing ones and is expected to cross 80 million units by
end of the year.
The
company's international come back started with the Moto G launch in India last
year and it strengthened its position in the consumer's mind with the global
launch of Moto E here, which has been sold out since it was put on sale on
Flipkart.com. The US-based company had wrapped up operations in India in August
2012, but has chosen the online-only strategy on its come back into the India
market since late 2013.
Motorola
Mobility, which is in the transition phase of being transferred to Lenovo from
Google, said that verification of IMEI numbers with Indian mobile operators was
carried out at the back-end. It added that the problem emerged in a single
batch due to a 'one off error' and that "measures have been taken
internally that can't be disclosed."
Analysts
are divided on the impact of this situation on Motorola with some of the view
that it may create a chink in the company's online-only strategy with others
highlighting that the incident was a small one-off.
"It's
good that Motorola acted proactively and offered either to exchange the devices
or refund the money which would help them pacify the consumers to certain
extent," said Gartner's principal analyst Vishal Tripathi. "But
somewhere, this situation will shake consumer's confidence and would impact a
bit of brand value".
A
Delhi-based industry watcher said that despite having a retail presence only
online, the device maker has offline service centers and a call centre for
resolving any issue faced by its customers.
"The
company has taken responsibility and owned up immediately. Moreover, such a
problem occurs very rarely and it's a small issue," the person said.
