The science of smartphone batteries and how to keep them charged - li ion battery cell

Every time a new iPhone is released, every Apple enthusiast wants to have a feature: improve battery life.
We may disagree on the headphone jack, but we all want smartphones that can hold more power.
How else can we catch the Pokémon?
The latest video from the American Society of Chemistry gives some advice on making the battery life longer
Of course, all of this is knowledge of chemistry.
Smartphones like the iPhone use lithiumion batteries.
They are light and charge longer than other types of batteries, but they also start to degrade once they are made.
Your smartphone battery will get worse and worse over time and will eventually die (
Although to be honest, you might break the screen before that).
Its final demise is inevitable.
But you can postpone the inevitable.
First of all, let's eliminate some myths: you don't need to keep your electronics powered off all the time before charging.
This "fact" is actually from nickel-
Mainly battery.
These batteries go through something called a "memory effect" and if a battery that is not fully discharged is charged with a partially full battery, it "forgets" some capacity.
If you have three eggs in your fridge and leave nine empty places in your beautiful little egg rack, but go to the store and buy only six eggs to fill these places, that's too
Nine seats in the morning and nine eggs after shopping. But wait!
You can have 12 eggs in your egg rack. Disaster.
Just like you can remedy this ridiculous egg distribution by buying a call after you run out of that nasty nine eggs, nickel batteries can usually "remember" their full capacity by running out to zero and starting again.
One of the advantages of lithium --
Ion batteries are not as forgetful as we assume egg eaters.
Therefore, it is not necessary to exhaust the battery to zero.
In fact, as explained in the video above, you 'd better keep the battery at 50-
Dessert.
As Eric Limer explained for Popular Mechanics, lithium-
The charging capacity of the ion battery depends on how much lithium ion it can embed in both electrodes.
These components degrade and hold less ions when you go through the charging cycle.
The Battery University recommends a partial discharge, because the burden on the cell phone battery is greater from scratch.
If you keep running out of it, your battery will lose capacity faster.
But the real lithium is heat. ion killer.
Heat accelerates all the chemical reactions, and the chemical reactions inside the battery are no exception.
Not only can the process of battery drainage be accelerated in the short term, but it can also cause the battery to degrade and hold less ions.
Even the heat of your body is enough to help kill the battery faster
So try not to put your phone in your pocket.
Finally, if you need to put the phone down for a while and don't want it to die completely, charge it to about 50% before you turn it off.
Batteries that are not charged can become unstable or even explode, so smartphones and laptops fail
If the battery is dead, it will kill them safely.
The neck hurts, but it's better than a cell phone explosion.
At this point, please consider this as a reminder to open in your Galaxy note 7.
These phones are recalled due to a battery failure that occasionally causes them to catch fire.
To protect users who may not be able to respond to Samsung's recall, the company has released a software update that keeps the phone's battery at 60% or less
Probably to avoid overheating.
