Every year smartphone owners beg companies to build phones with better batteries and every year these companies only give us lighter and thinner devices that still deliver mediocre battery life. Will this ever chance? If a fuel-cell developer called Intelligent Energy has any say, we could have smartphones whose batteries last up to a week within the next two years. More →
With each passing year, companies like Apple and Samsung manage to make smartphones faster while also packing them with increasingly advanced features. That’s all well and good, but battery technology, in contrast, has seemingly hit a plateau in recent years. It’s hardly a surprise, then, that the one feature request shared by most all smartphone users is prolonged battery life.
A lot of the tips we’ve been hearing about how to improve the performance of our batteries turn out to have been tall tales. CNET’s Sharon Profis has put together a great video that specifically debunks three of the most common myths about batteries: Namely, that you should wait for batteries to completely drain before recharging them, that you should charge a device fully the first time you turn it on, and that you shouldn’t “overcharge” your battery by leaving your phone plugged in after its battery has fully charged.

Despite numerous technological advancements that have given us an increasing number of highly sophisticated toys in recent years, we still haven’t solved all our problems with battery life. Yes, battery life is a top concern for many smartphone makers and also for electric vehicles and almost anything that requires large amounts of energy to operate. Battery life and battery efficiency have yet to get a definitive fix, but various research products are aiming to offer the fix we’ve been waiting for.
Such is the case with a team from the University of Cambridge, which has created the “ultimate” battery: a lithium-oxygen battery that uses graphene electrodes to offer high-density, more than 90% efficiency, and can be recharged for up to 2,000 times. More →
Remember Iron Man’s transparent smartphones? They might become reality sooner than you think thanks to an unusual new type of battery that’s not only transparent, but it can also charge via solar power. The technology could also be used for other products in the future, such as smart office and home windows that would be able to let the sun’s light pass through them, but also recharge and store energy.

Now this is intriguing. The Telegraph over the weekend reported that U.K.-based tech company Intelligent Energy has invented a new type of smartphone battery that runs on hydrogen and can purportedly last a week per charge. More →
What does your smartphone’s battery look like when it overheats? A little bit scary, as a new video posted by University College London shows. The video was posted as part of a project being conducted by UCL Chemical Engineering PhD student Donal Finegan and Dr Paul Shearing, who are trying to understand more about the reasons that lithium-ion batteries fail. This is important because these batteries are increasingly being used not only in our phones but also in electric cars. More →
If there’s one common complaint shared across Android and iPhone users it’s that battery life could always stand to be better. Though there have been advancements in lithium-ion battery technology over the years, the software we run these days is much more complex than it was during the early smartphone era days. In other words, battery efficiency is having a tough time keeping up with how rigorously we use our devices.
No matter how advanced our gadgets get from year to year, the fact remains that battery technology isn’t able to keep up. Just look at the Apple Watch, a smartwatch that’s going to be more powerful than the first iPad, but which will need constant charging. Similarly, many mobile devices that are already available in stores aren’t able to meet the battery needs of all consumers either, even though handset makers are constantly devising ways to improve battery life.
One such battery project belonging to MIT startup SolidEnergy might provide a solution for significantly increasing battery life on mobile devices starting as soon as this year. More →
Researchers from Stanford including former U.S. Secretary of Energy and Nobel laureate Steve Chu are currently working on “fixing” lithium-ion batteries in order to offer a longer charge to various devices that require such batteries, including smartphones and electric cars. More →
Two scientists from the University of Toronto have figured out a way to create cheaper, lighter and more flexible solar cells, CNET reports, which could allow more users in the future to harness energy directly from the sun for different purposes. More →
Researchers from the University of Tokyo in cooperation with the University of Kyoto and Japan’s National Institute for Materials Science are studying a new technology that would significantly improve charging times for Lithium-ion (Li-ion) batteries, which could then be applied to various products including electric vehicles as well as smartphones and tablets.

The LithiumCard isn’t the only credit card-sized battery for mobile devices seeking crowd-funding, as there’s also a TravelCard project that offers iPhone and Android smartphones exactly the same perk: a credit card-like device that packs enough energy to bring life to a dying smartphone. More →
