Kim’s Opinion: Smartphone batteries are a killjoy

Remember the last time you got a new smartphone? All the new parts, charging cable, setting it up, signing in to services, adding apps. It was all so fun.

The most amazing thing of all? The battery lasted for days. Now, not so much. It’s science.

Have you ever wondered why your gadget’s lithium-ion battery lasts for days when it’s new and then not anymore? Many people believe manufacturers do this on purpose to entice you to buy a new phone.

Well, top researchers at Stanford, M.I.T. and the University of Bath discovered how we thought a lithium-ion battery works is wrong — as in dead wrong.

It was thought lithium flows in one direction. The researchers found it flows back and forth, creating empty pockets that damages the battery. This destroys the battery’s lifespan.

Armed with that new knowledge, look for longer-lasting batteries in a few years.

But isn’t it amazing? Your smartphone is millions of times more powerful than all of NASA’s combined computing in 1969 and a battery is the killjoy.
