Step By Step Process On: How To Charge Battery Correctly?

Here I will explain you step by step process of how to charge battery correctly? let’s see how to charge battery correctly.


  1. Android phone with a lithium battery
  2. Battery charger
  3. Knowledge of phone’s charging habits


First, understand the basics of lithium batteries in phones. These are the most common type of battery in use today, and there are pros and cons to using them. One con is that they can suffer from “memory effect” if they are constantly charged to the same level (say, 60%). This will eventually lead to the capacity of the battery decreasing to that level. However, this effect is much less prominent in lithium batteries than in older types of batteries like nickel-cadmium or nickel-metal hydride. With those older batteries, it was always important to make sure you depleted them fully before recharging, and to always recharge them to 100%.

With modern lithium batteries, it’s actually the opposite that is true. Because of the chemistry of these batteries, you want to minimize the amount of time they spend without a very high or very low capacity. Both of these put strain on the battery and can lead to degradation over time.


That’s not to say that having a battery at 100% all the time is bad. Your battery is there to be used, after all. But if you’re constantly charging it from 80% up to 100%, it’s going to age faster than it would otherwise. This is because of the strain that this puts on the internals of the cell.

Some recent Android phones, like the ASUS ZenFone 7 Pro, actually give you a score for your charging habits. This lets you know if it would help to make some changes. And on the ASUS ROG Phone 3, there’s even an option to cap the regular charge limit at 80%. This is because that phone has a ginormous 6,000mAh battery, so you probably don’t always need that full charge to get through the day.

Other brands, like OnePlus, have software features that learn when you normally wake up and make sure to only charge the final 80% when it’s actually needed. This leaves you with a full charge in the morning. It’s a really nice balance between battery health and practical use.


Overnight charging is actually a really interesting point here. Because obviously charging overnight risks your phone being at that less-than-ideal 80-100% range for longer. That’s even more true when you consider fast charging.

Fast charging can already age your phone battery more quickly because of

How Do You Charge A Battery Properly?

Batteries are an essential part of our lives – they power our phones, our laptops, and even our cars. But how do you charge a battery properly?

It turns out, there is a right way and a wrong way to charge a battery. The wrong way can shorten the battery’s lifespan, and even cause it to burst into flames. So, it’s important to know how to charge your battery properly!

Here are some tips on how to charge your battery the right way:

1. Avoid extreme temperatures.

Batteries don’t like extreme temperatures, either hot or cold. So, when you’re charging your battery, make sure to do it in a cool, dry place.

2. Don’t overcharge.

You might think that it’s better to keep your battery topped off, but that’s actually not the case. Overcharging a battery can shorten its lifespan and even cause it to catch fire. So, it’s important to only charge your battery until it reaches 100%, and then unplug it.

3. Use the right charger.

Not all chargers are created equal. Some chargers are made specifically for certain types of batteries, so it’s important to use the right charger for your battery. Using the wrong charger can damage your battery and shorten its lifespan.

4. Avoid charging overnight.

Leaving your battery plugged in overnight is a bad idea. Not only is it a fire hazard, but it can also damage your battery. If you must charge your battery overnight, make sure to unplug it as soon as it reaches 100%.

5. Don’t use a damaged charger.

If your charger is damaged, don’t use it! Using a damaged charger can damage your battery, and even cause it to catch fire.

following these tips, you can charge your battery the right way and avoid damaging it.

At What Percentage Should I Charge My Phone?

We all want our smartphones to last as long as possible, and one way to help extend the lifespan of your device is to avoid charging it to 100%. While it may seem counterintuitive, it’s actually better for your battery to charge it to only 80-90%.

Here’s why: when you charge your phone to 100%, the battery is subjected to what’s called “voltage stress.” This stress can lead to a deterioration of the battery’s capacity and longevity.

So what’s the best way to charge your phone? Avoid full cycle (0-100%) and overnight charging. Instead, top up your phone more regularly with partial charges. Ending a charge at 80-90% is better for the battery than topping up to completely full.

Of course, there are exceptions to this rule. If you’re going to be without a charger for an extended period of time, it’s better to charge your phone to 100% before you go. And if you’re going to be using your phone for an intensive activity like gaming or navigation, you may want to charge it to 100% to avoid running out of power at an inopportune time.

But in general, it’s best to err on the side of caution and keep your phone’s battery somewhere between 80-90%. Your phone will thank you for it in the long run!

Furthermore, It’s best to charge your smartphone by avoiding full cycles and overnight charging. Instead, charge it more regularly with partial charges. Ending a charge at 80-90% is better for the battery than charging it to 100%.

At What Percentage Should I Recharge My Battery?

How much should you charge your phone battery? It depends on who you ask. Apple, Google, and Samsung all have different recommendations.

Apple used to recommend charging iPhones to 100 percent, but it has since changed its tune. Now, the company says that “it’s fine to use your iPhone in this state.” Google’s recommendation is similarly straightforward: “Charge as much or as little as needed. You don’t need to teach your phone how much capacity the battery has by going from full to zero, or zero to full, charge.” Samsung advises charging regularly and keeping the battery above 50 percent.

So, what’s the best practice? It seems that there’s no consensus. Which means that it’s up to you to decide how to charge your phone. If you’re worried about battery life, err on the side of caution and charge more often. If you’re not as concerned, feel free to charge less frequently.

As well as that, Google and Samsung both recommend not fully charging or fully depleting your phone’s battery. Instead, they suggest charging it regularly and keeping the battery above 50 percent.

When Charging A Battery Which Goes On First?

When you are charging a battery, the positive terminal should be connected first, followed by the negative terminal. When disconnecting the cables from an old battery, you should disconnect the negative terminal first, followed by the positive terminal. This ensures that there is no sparks or short circuits when connecting or disconnecting the battery.

Along with, It is important to disconnect and connect batteries in a certain order to avoid damage. To disconnect the cables from an old battery, first disconnect the negative cable, then the positive cable. To connect a new battery, first connect the positive cable, then the negative cable.

What Percent Should You Charge Your Phone?

There is no definitive answer to this question since it depends on a number of factors, including how often you use your phone, how long you keep your phone charged, and what kind of phone you have. However, as a general rule, it is generally recommended that you charge your phone to between 50-80% to ensure optimal battery life.
