3 Myths About Smartphone Batteries That Need to Die - buy lithium ion battery

Nothing is more important than taking out a new smartphone from the box and enjoying the time you can use it between two charges.
But about a year later, battery life began to decrease.
What caused it?
We debunked some popular myths about extending battery life.
You may have a friend or even a smartphone salesperson telling you that it's not good to have the battery plugged in overnight.
But on the other hand, who wants to wake up at three in the morning. m.
Unplug their phones?
Relax, my friend.
The battery of your phone is smarter than you think.
When you plug in your smartphone at night, lithium-
The ion battery starts charging slowly until it is full or "saturated" at 4 ". 1 volts.
"Then it's off," said Isidor Buchmann, founder and CEO of Cadex Electronics and founder of Battery University, an educational site.
"It's like it's on the shelf and there's no connection at all.
Therefore, if the charger is working properly, it is impossible for your mobile phone battery to "overcharge" beyond the limit of 4 knots ". 1 volts.
But is it harmful for batteries to be fully charged for a long time?
It depends on what you expect from your cell phone battery.
"If someone wants to keep the battery forever, then you can call it 'overcharging, '" says Bachmann '. ".
"But consumer products like smartphones, people don't care about battery life.
Two or three years later, the glass broke and you bought a new one and the old battery still has some longevity.
"Technologies like satellites and electric vehicles that have a longer life span are another matter.
In this case, the engineer must take special precautions to extend the life of lithiumion batteries.
For example, a rechargeable battery in an electric car will not fill up 100% of the power and will not run out of all power.
"They work in the middle where the battery has the least pressure over time," says Bachmann . ".
So you don't need to wake up at night and unplug your phone full of electricity.
The whole purpose of charging a smartphone is to maximize its time before plugging in.
You want it to be 100% in the morning so it can last for the day (or most of the time ).
No, before charging, it's better to plug in your phone every once in a while throughout the day instead of letting the battery run out completely.
Capacity of 40 to 80% is the best choice.
As stated on the Battery University website, "similar to mechanical devices that wear faster after a lot of use, the discharge depth (DoD) determines the number of cycles of the battery.
The smaller the discharge (low DoD), the longer the battery lasts.
If possible, avoid full discharge and charge the battery more frequently between use.
"(The Defense Department refers to how much energy the battery provides.
The Ministry of Defense is 0% of the fully charged batteries;
In the 70% charged battery, it is 30% ).
However, once every three months, the battery should be calibrated by letting it run out until the "low battery" light appears and is fully charged.
In fact, the threat of heat to battery life is much greater than your charging practice.
Putting your phone on a sunny windowsill or car dashboard is a guaranteed way to drain its capacity.
"It's like a box of milk," says Bachmann . " Bachmann really wrote a book about rechargeable batteries.
"It won't last long if it's not in the fridge. With a lithium-
Ion batteries, corrosion will lead to aging of the battery.
"Interestingly, if you store lithium, there may be problems with the combination of overheating and full charging
For a long time between use, the ion battery.
Battery University tested lithium.
The ion battery was stored at different temperatures for a whole year.
Batteries stored at 100% degrees Celsius (104 degrees Fahrenheit) will lose 35% of their total capacity within a year.
Under the same conditions, a battery with an initial charge of only 40% will lose only 15% of its capacity after three months.
That's why people in the battery industry store and transport batteries at controlled temperatures without fully charging them.
Again, does that mean you should put your smartphone in the fridge for the night?
No, it's crazy, unless you're not going to use it for a year, or you just like the feeling of using an iPhone in the morning.
For all lithium, a certain degree of loss of capacity is inevitable
The ion battery, Bachmann explains, does not have any factor that will allow your battery to fully charge, completely run out, too much circulation, too much heat.
But all this will have an impact on them.
The good news is that your child will throw the phone into the toilet before the battery runs out.
