Battery Charging Methods & Terminology: The Definitive Guide

0

After the introduction of iPhones, the mobile phone industry has seen a revolution. The advancement it has gone through made smartphones an essential ingredient in our daily life. Now, every single person has either a smartphone or a tablet. 

Every smartphone has a different configuration, some might have a good screen other might offer you a better performance. So, you can choose one according to your need and desire. We often overlook something that powers your smartphone, that is its battery.

In this article, we are going to cover that topic. And are going to burst a lot of bubbles. Battery Capacity and Battery charging are summoned by a lot of myths and illogical statements. 

Let’s help you in getting in-depth knowledge about “battery” and its charging.

The chemistry behind battery:-

Battery Charging

Every action in this world has to undergo a chemical process and your battery is no exception to this rule.

All the battery manufacturers tend to have their unique way of making a battery. One thing that’s common between all of them is that all of them store chemical energy but the difference arose due to the variation in their chemical process.

If you have a nickel-cadmium battery, then the chances of your battery getting charged quickly are good but its biggest demerit is that the battery starts to deteriorate if you constantly charge it without it being fully discharged, these phenomenon is called memory effect.

On the other hand, if you have nickel metal hydrate batteries then you have to keep checking if your battery is full charge as they are very vulnerable to overcharging.

But the most prominent battery type we are witnessing nowadays is the Li-ion or Lithium-ion battery. They have some merits and demerits that we are going to talk about in this article.

Lithium-Ion Battery:-

Battery Charging 1

As mentioned earlier Lithium-Ion batteries are the most common battery nowadays. So, let’s see a few of its characteristics:-

Li-ion Lifespan:-

Lithium-ion batteries are free of any kind of demerits that we have seen in Nickel Cadmium or Nickel-metal hydrate. They neither have the memory effect nor are they vulnerable to overcharging.

But one their biggest demerit is that they deteriorate every time after the completion of the charge-discharge cycle.

So, you might have to constantly replace them as each of these batteries are made to work till a particular rated cycle. And it is better to replace them afterward as they can be dangerous at times. 

But thanks to the advancement in technology, the lifespan of these batteries has increased. They have stretched their charge-discharge cycle window.

The only problem due to this advancement is that the battery is fixed in the device itself and replacing it can be a little heavy on your pocket.

Increase your battery lifespan:-

Even though, your charge-discharge cycle is responsible for your battery getting deteriorate it is not the only thing. Here is the list of things you can do to increase your battery lifespan:-

Turn off your mobile data:-

If you are not using your mobile data or wifi it’s better to turn them off for a better battery lifespan as they both consume a lot of your battery. 

Decrease your brightness

It is advisable to decrease your phone’s brightness if you are using it indoors, even better you should enable adaptive brightness. You should decrease your display’s timeout as to decrease the screen on-time to increase the battery life

Kill the background apps:-

Disable background applications as they tend to suck battery even if they are not being used.

Disable all the connectivity:-

One of the best ways to disable all the connectivity is to just turn airplane mode on at times, or better shut down your phone if you are not using and are not expecting a call.

If you can’t do that because of your job or something, then you should at least disable GPS when you are not tracking or being tracked.

Block Adds:-

Androids are very notorious for showing ads. Apart from them being super annoying, they shrink your batteries as well. So, disable advertisements while browsing, chrome as this option.

Proper Mobile Temperature:-

Don’t keep your mobile in a hot or cold condition, the best temperature for a smartphone and its battery is anywhere between 6 to 30-degree Celcius, anything above or below that can be bad for your device.

Don’t use your phone while charging, as it can give your device heatstroke and can cause your battery to deteriorate.

Good charge window:-

Don’t allow your battery to go past 30% or exceed 80%, as you don’t want your device to feel the urge of charging the device quickly by going down 30% and to complete a charge-discharge cycle by reaching 100%.

Say ‘NO’ to third party chargers:-

It is recommended that one should not use a third-party charger as there are a lot of manufacturers who tend to have a specific charger and charger’s rating.

How to revive a dead Lithium Battery:-

Battery Charging

If you discharge your battery time and time again it becomes dead. Now you can’t charge your battery, because your charge is manufactured to detect the battery if it has some voltage.

For example, if there is a battery, which has the least voltage magnitude of 20V, and if your battery’s voltage is lower than that your charger will not be able to detect it, therefore, will not be able to charge the battery.

To revive your battery you should first connect it to a power source(do not connect it directly to the main supply) and once the battery’s voltage has reached the minimum threshold voltage. Your charger will be able to recognize it.

Note: In no circumstances plug your battery to the main supply

If this didn’t work then you should replace the battery and get the new one.

Ensure your battery’s safety:-

Lithium batteries are very vulnerable to malfunction but because of the latest advancement, you don’t need to go above and beyond for its safety.

Ensure a smooth surface:-

But if you are a little conservative and you have a previous-gen laptop, smartphone, etc then you should try looking at the surface of the battery. If you see any kind of bulge then it means that it’s the time to replace your battery. 

Maintain its calm!

Another thing that you can do to ensure your battery’s safety, firstly don’t let your device overheat, and even if it did then wait for the battery to cool-down before charging or using it.

Maintain your Jack(charging port):-

You shouldn’t use an improper jack, as it can cause your charger to heat up and its power deteriorates. 

Keep it dry:-

This is one is OG. We have heard our moms screaming “do not leave your phone on the dining table”.  It’s not the dining table that is bad for your phone, it’s the water that might get spilled on it.

So, make sure that you keep it away from any presence of H2O. In case of your phone getting a little wet, you should immediately keep it near the sun, if your device has a removable battery then remove it.

One thing that you should always keep in mind, your battery is very crucial. A malfunctioned battery can explode sometimes. So, always keep this at the back of your mind. 

Advantage and Disadvantages of Li-ion battery:-

Battery Charging 3

Yes, Li-ion has many advantages but some disadvantages as well. In this section, we are going to discuss both its merit and demerits. 

Advantages:-
  • Li-ion provides you with higher energy density, with the help of which manufacturers can easily extend the battery capacity by doing some twitches in its electronic components.
  • Can either be discharged or fully charged unlike nickel lithium or nickel-cadmium.
  • It is very easy to maintain these batteries as they don’t have any memory.
  • Can be charged very quickly if the right charger is used.
Disadvantage:-
  • Very vulnerable to heat and cold. Any extremes are not appreciated here.
  • The old Li-ion batteries age pretty quickly, the have someone of the worst aging effect, when stored in a place with lower temperature, almost 30% of your battery will be sucked out.
  • They are more expensive than the previous nickel-cadmium battery, but since they work better the value is there.

Myths about battery Charging:-

After going through the previous sections, there might be few doubts that might have throttled your mind, a few of the old thoughts that your parents, relatives, or friends might have told you. It’s time to burst all the mythological bubbles.

1. Overnight Battery Charging will make your battery malfunction:-

The thing with this myth is that even though I know that it’s false, still, I can understand where it’s coming from. As mentioned earlier in the article, the previous version of Lithium batteries can deteriorate after the completion of charge-discharge cycles. 

Another thing is that if your phone heats while charging then it is better for you to not charge it overnight as it is not the overnight charging that’s causing damage, it’s your battery that needs a replacement.

And you need to replace it now as it can be really dangerous. You might have heard a few incidents where someone’s iPhone has exploded, that’s because of their battery and not the overnight charging.

2. If you want to get a shock, talk while your phone is charging:-

This is not particularly true, but there is some aroma of truth in it. Talking to someone on a phone is completely normal in this millennial world but the problem begins when you start using a third-party charger.

Third-party chargers or the chargers who are not compatible with your device can give you shock through your metal fingerprint sensor or your metal speaker.

If you are using a perfectly normal charger then it’s fine until your phone heats up and starts hurting your ears

3. If you turn off your Phone it will never start again:-

It’s absurd. This is as false as the flat earth. Don’t you turn your laptop or desktop off? If they didn’t stop working why won’t your phone do that.

The only case when you should be beware of your phone getting switched off is when it automatically switches off(for that look “How to revive a dead Lithium Battery” section)

Your smartphone serves you day and night, therefore, it needs some rest. Which is why you should try to give it a break time-to-time.

4. Auto-brightness is false:-

Auto-brightness is one of the best features ever introduced in smartphones. Auto-brightness can save a lot of battery for you because you might not need the harsh brightness caressing your eyes in an indoor scenario.

In one of the surveys, it was concluded that this feature can save you up to 20-30% battery in the case of Android phones and 50-60% for iPhones. Therefore, it is advisable to use Auto-brightness if your phone has one.

5. Charge your battery one when it is 0%:-

This rule is a thing of the past and also the one who believes in it. This rule applies to the old nickel-cadmium batteries, but because of the introduction of Li-ion, no manufacturer uses them.

So, now you don’t have to reduce your battery to nil before charging it, instead, in my, opinion you should charge your phone when the battery is somewhat between 30-40%.

6. No third-party chargers:-

This rule is somewhat true as it is very difficult to find the right charger. But if you can, then go for it. These chargers are made up of cheap materials, these materials are vulnerable to heavy electricity.

A cheap third-party charger might be made up of substandard components, especially a substandard data cable, they may use the wrong voltage or ampere charge.

That’s one of the biggest reasons why the company keeps saying “buy from us”. That’s because they know the compatibility of their devices and what will be best for it. But if you can search and find a well-branded charger then you should buy it.

7. Web Browsers accelerates the draining of your battery:-

This myth is not entirely false. Yes, your browser can accelerate the draining of your battery, that being said, you should not stop using the browser completely. What you can do is to restrict yourself from watching youtube videos on it.

The biggest battery drainer is the one thing that you are addicted to. For some of us, it might be games such as PUBG or Fortnite and for others, it can be Social media such as Instagram and Facebook.

When it comes to Instagram or Facebook, the biggest battery drainer is the video that you watch on these platforms. As they are loaded with graphics, sucking battery out of your phone.

8. You are dealing with battery issues, download this:-

Downloading another application to save battery which is drained due to excessive application, is bullshit. The best way to save your battery from draining out is to not download too much and use the in-build battery saver.

9. Always try and keep your phone fully charged:

There are some freaks out there, who don’t like their phone battery to drop a notch. They want their battery to always be 100%, not even 99%.

I just want to ask them, what do you think would be better: your phone’s battery being 100% or your phone’s health being 100%.

There is nothing wrong with charging your phone up to 100% as we have now removed the charge-discharge cycle out of the occasion, but anything can damage your phone and excessive certainly can.

10. If your battery is over-heating put it in the freezer:-

Please don’t do that, your battery is vulnerable to extreme heat as well as extreme cold. Therefore, snath this page from your book of ideas. Overheating of your phone’s battery is a serious problem, therefore, do not take it lightly.

Try getting in touch with a proper consultant. You should try contacting your phone’s customer care for the best possible support. If your phone has a non-removable battery then please don’t try to snap the battery out of it somehow.

Summary:-

A nickel-cadmium battery will charge quickly, but its biggest demerit is that the battery starts to deteriorate if you constantly charge it without it being fully discharged, these phenomenon is called the memory effect.

Nickel metal hydrate is very vulnerable to overcharging and heating.

Li-ion is the current chemical element used to make batteries, they neither have the memory effect nor are they vulnerable to overcharging.

They are a lot of ways by which one can easily increase its battery such as turning off the mobile data, decreasing its brightness, blocking adds, etc.

Sometimes when you discharge your battery to an extent which is less than its minimum rating. As your charger will not be able to detect the battery.

To revive the battery one can use an active component such as a voltage source, just plug-in and let the battery absorb voltage till it equals the threshold voltage.
