Phone Battery Lasting 400 Years!


Imagine your phone coming with a battery that could last for 400 years! That's a good news.

According to the news, the technology was found by mistake when the university student, Mya Le Thai, was experimenting different metals and scenarios to see what happens. When she used manganese dioxide and a type of electrolyte gel to coat the gold wires, she saw the drastically longer battery life cycle.

A laptop or phone's battery's lifetime is measured on how many times battery could be made completely empty and then completely recharged. That's one cycle. And normal laptop batteries could run 300 to 500 such cycles.

What Mya Le Thai found was that with the new way, the battery sustained for over 30,000 cycles. That's equivalent to a battery lasting for up to 400 years! That's immense!

Though, they have only mentioned laptop batteries, but I guess they would be able to use the technology for mobile phones and all the other rechargeable devices.


 Update: The article previously interpreted the technology as not having to recharge the battery at all. But, as pointed out by a fellow reader, the battery still needs to be recharged but only its lifespan extends up to 400 years. Thank you, Emlyn O'Regan for pointing it out.

User just gets what he wants in the minimum time and with best support from the software side. Microsoft needs to just do that with the whole Windows. Let's consider Office's awesome things that is making them popular among users. Why Office is best is because it takes care of the smallest interaction of the user with the software i.e. automatic spell-check, automatic capital first word, automatic bullets and a lot more that I personally don't know. But, I understand that Office tries to make things better at every level of interaction the user has with Office suite. That's also the case of most iProducts and Android software. They are tracking the littlest things and are trying to make them easier, better and deliver a good experience to an average user. Now take a look at Windows. To my personal experience, for most average u

iPhone 7 Hints Radical Design Improvements of the Next iPhone

It is obvious, isn't it? Apple is planning to remove the traditional home button from its iPhone and when it does, it will replace the functionality with a thinner home button at the lower bezel, integrating the touch ID on the screen and thus shortening upper and lower bezel to reduce the form factor of the iPhone. Meanwhile, making the home button static and backed up by the taptic engine in iPhone 7 is only a field test and also getting people accustomed to the idea of taptic engine feedback from a virtual button or a long thin strip of a button at the lower bezel or whatever type of button Apple chooses to make iPhone smaller in hands. Otherwise, do you really think that an 'inconvenience' like making the whole lower part of the phone vibrate when pressing the home button on iPhone 7, is a thing that Apple would allow? I don't think so. Apple takes care of the littlest inconveniences and this one is a big one comparatively. But, if you think that in the ne
