IS IT NECESSARY TO CHARGE A NEW SMARTPHONE FOR 8HOURS

 

After buying a new phone

We all have a question in mind

How many hours to charge this new smartphone

Smartphone shop vendor says to charge the new phone for 8 hours

Is it really necessary to charge a new smartphone for 8 hours

As it won’t take 8 hours to charge the newly bought smartphone

Then why these smartphone vendors are saying to charge the newly bought smartphone for 8 hours

There is a science behind this

Let’s see the science behind this

Actual topic 

A few decades before

Smartphones and other gadgets come with nickel-based batteries, that is nickel-cadmium battery or nickel hydrate battery

But now

It’s changed to lithium ion or lithium polymer battery

So we have got another question

Why the battery has changed from nickel-based batteries to lithium-based batteries

Because lithium-based batteries are better than nickel-based batteries

Let’s see why

Nickel-based battery has many disadvantages which are not there in the lithium-based battery

Let’s see that

In nickel-based batteries that is nickel cadmium or nickel hydrate battery, there is no provision to check whether the battery is fully charged or not

So these batteries are charged 8 hours or charged overnight

Now let’s see the second disadvantage of nickel-based batteries

Nickel based batteries have memory effect

Let’s explain this by using an example

So that even non-techy people could easily understand this

Consider you charge nickel-based batteries daily when it becomes 40% and charge till 89%

Then the nickel-based battery consider 40% as a lower point and 80% as the highest point

It will keep a memory for these lowest and highest points in it

Now let’s see the third disadvantage

The self-discharge rate in the nickel-based battery is higher as compared with the lithium-based battery

Another advantage of using lithium-based battery over the nickel-based battery is that lithium battery is slimmer than nickel-based battery

Now 99% of batteries in smartphones are lithium-based batteries

 

CONCLUSION

There is no need of charging a new smartphone for 8 hours or overnight. It was only  true for nickel-based batteries

But now it’s not needed to charge 8hours,  Now more 99.99% of batteries comes with lithium-based batteries

Lithium-based batteries are only needed to charge until the battery becomes full
