Charging Overnight

Most of us use our cellphones as an mp3 player, a portable game console, a television, and a notebook - all in one little box. As a result, a charge is required to power up the apps and provide you with a better experience. As a result, its battery must be in good working order.

What can we do to make a battery last longer?

Many people advise against charging your phone overnight. “Everyone wants their phone to be completely charged when they wake up in the morning so that it will last the entire day.”

People would not advise leaving your phone plugged in all night, which may seem unsafe and paradoxical.

Let's go further!

When the battery is connected in for a long time, it has a negative impact on its longevity (only little degradation occurs). Lithium-ion batteries are used in the majority of current gadgets. Despite the fact that lithium-ion batteries are rechargeable by nature, they are extremely sensitive to continual high voltage and current, such as that found in household plugs (230-240 V in India / 110 V in the US).

Consider this scenario: you leave your phone plugged in and charging overnight every night for a year, or more than three months in total. A battery's capacity will undoubtedly be reduced as a result of this level of stress.

Thankfully, the situation isn't as severe as it appears, because every brand's manufacturer is aware of the problem and is doing all possible to prevent battery damage.

For example, when your battery capacity reaches 100 percent, the adapter will turn off the current to the battery, and when it reaches 99 percent again, it will continue charging...actually, that is the problem.

So that the top companies can come up with a better solution, which stipulates that a very little current (charging current) should be retained, almost exactly 0.03 amps, in order to avoid the aforementioned effect on the smartphone. Because the mobile processor will be performing certain minor tasks such as OS management, the 0.03 amps current will flow.

It is completely safe to charge your phone while it is turned off because once the battery level reaches 100 percent, there will be no electricity flowing because the load is turned off.

Basically, a USB cable consists of 4 conductors namely:

Data+, Data-, Positive, Negative.

          Because batteries can only store dc, the adapter's output will be a DC supply. So that the Red(+ve) and Black/Grey are both present (-ve).

Let's not connect a voltmeter in series to the red wire and a voltmeter in parallel to the red and black wires.

We’ll get the following data on an avg smartphone:

Voltage, battery level and current data

The difference in volts and current (when voltage is low, the current rises, and vice versa) is caused by the RESISTANCE in the circuit, which is easily understood by Ohm's Law.


Voltage and current rating after 100 percent


    You'll notice that some of the items in a tech store are more pricey than others if you look closely.

True, high-quality chargers contain circuit chips with good ratings that prevent overcharging. As a result, it's a good idea to invest in a superior charging adapter.

 And what about charging cables?

    Poor-quality cables/adapters: Your phone will overheat as a result of these. Batteries are sensitive to heat. That's why leaving your phone in a closed car in the heat of summer is so dangerous to it. Until you cool it off, it'll be sluggish and slow. 

A battery left on charge will generate heat, but it will come from the interior of the phone's body, which is probably more damaging in the long run.

You can slow down this damaging process by removing your phone from its case while charging it, but this will not totally address the problem. There's also some additional advice flying around the internet that I'll have to disprove as lies.

So think about investing in a high-quality adaptor for your phone that is well worth the money.

The capacity of batteries has increased to match the demands of our more power-hungry electronics, while their size has dropped. The truth is that engineers could create a new type of lithium-ion battery that could charge in seconds and last for more than a day.

Short Answer !!

          Of course, YOU CAN CHARGE YOUR PHONE OVERNIGHT, nevertheless, the negative impact on your smartphone's battery is minimal! .. If you expect to use your phone for more than 6 years, for example, don't charge it overnight... The battery could last for 5 years plus a few months. Normally, most of us would upgrade to a new phone before 5 years. As a result, it won't be a big deal!
