The state of smartphone battery technology [early 2016]

Good battery life is key to any smartphone. Sure, you want a bigger display or a better camera, or even a faster fingerprint scanner (biometric security FTW), but, if there is nothing left to power the device at the end of the day then what’s the point?

Every year we get to see some of the best smartphones on the market. Ones with bigger screens, more efficient processors and great cameras. Yet it seems that battery technology remains stagnant all year round. Actually battery technology hasn’t changed much for decade.

Just a second, guys. Let me plug in my laptop. So where were we?

Do you remember last year’s Samsung Galaxy S6? One of it’s most touted features was a 2550 mAh battery. Pathetic.

So what’s going on? Why are smartphone batteries so lame? It all begins with the infamous Lithium-ion cell. 

What is a lithium-ion cell?

You’ve probably heard about the Lithium-ion cell, right? According to Professor Wikipedia, who has a PhD in everything: A lithium-ion battery (sometimes Li-ion battery or LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.

So basically a Lithium-ion battery is just a cell where lithium ions move back and forth while charging and discharging. That’s all the knowledge I’m going to give you because any additional information might bore you all to death.

PROS: Lithium-ion cells have a relatively simple design, and it is easily maintained.

CONS: When used in smartphones, battery life sucks. Hard. Here’s why…

Limitations of the lithium-ion cell

Fun fact: it is said that modern-day smartphones have more processing power than the computers that were used by NASA to send men to the moon. This is the major reason why lithium-ion cells are inconvenient when incorporated with smartphones. Smartphones are a lot powerful when compared to their previous iterations. They seem to get more powerful and efficient with each passing year.

Faster processors are more power hungry, although they’re being built to efficiently utilize battery life. So, I came up with this mind-blowing equation which took me just a few seconds to make, really.

Powerful processors = bad battery life

I don’t want to live in a world where I’m constantly stressed about the percentage of battery life remaining on my smartphone. When I want ...
