Unless you live in a cave, this article highlights a topic that has come across all of our minds; Smartphone battery life. We have all been frustrated at having our phones die when we most need them. It is quite obvious that although many features of phones have been revolutionized with additions like ultra thin size and super light weight, the phones battery life seems to remain the same. To achieve optimum battery life would help companies dominate the market and contribute to very high sales. Even a phone that one has never considered before can pique the curiosity of buyers if it has excellent battery life. Imagine that, Blackberry coming back into the market because its phones can last for several hours even after incessant use. Chief technology officer Mujeeb Ijaz at A123 Systems states a concern amongst all buyers, “Give me a better battery because it doesn’t last long enough.” The message cannot be any more explicit, the Smartphone with the best battery life will be the first to be picked off shelves at Best Buy (if you still go there to actually buy products). However, every year we get a new phone that looks completely different than the previous one and has some different functions; however its battery life is pretty much the same. Companies have been working hard to improve their standing in the market in terms of attaining a better position in the domain of battery life. Apple, Google, Samsung, various Universities and even several start-ups are facing cut-throat competition amongst themselves in figuring out ways to extend the life of smart phones. Samsung has been designing new types of batteries with wearable computers in mind and it has introduced compact curved batteries that can be installed inside wristbands. It introduced Dream Battery last year, which uses solid electrolytes (instead of the liquid or polymer used by lithium-ion batteries) to eliminate the risk of explosions and other safety problems for flexible electronics. uBeam, a start-up in California, is experimenting with technology that involves piezoelectricity — a form of charge that is created in vibrations of certain crystals and ceramics. It is essentially attempting to develop a system in which devices pull energy from the air. Apple obviously has been trying its luck at battery enhancing technology for a while. It received a patent for a flexible battery that could fit in a wristwatch or tablet and even posted a job listing seeking engineers who specialize in solar energy. We can only hope that the technologies that are being developed now are truly effective and not a flash in the pan as we have continually seen for years. So the crux of the matter is that whoever comes up with the most effective and cheap way to keep out batteries alive longer will come out of this race victorious.
