Fast charging | Charging technology | mobile


Hey all, Welcome to Geeksforjobs

introduction :

Do you want to charge your phone fast? Want to know about the charging and discharging process? Confused between Warp Charge, Quick Charge, Flash Charge and Adaptive Charge? … Let’s look in detail from head to toe in fast charging.

Fast charge


Batteries are classified into two types based on recharging capabilities.

They are

  • Rechargeable batteries and
  • Non-Rechargeable Battery.


In general, these batteries have two electrodes. One is positive and the other is negative. And electrolytic catalysis reaction to convert it into a new substance.

Non Rechargeable:

Catalysis reaction occurs only once in non-rechargeable batteries, so once discharged there is no possibility of charging.


But in case of rechargeable batteries, catalysis reaction has the potential to occur every time after discharge.

Catalysis absorbs electricity when we recharge the battery and produces electricity, discharging a chemical reaction.

simple words:

In simple words a battery has two sides known as the electrolytic field.

When we started using our phones one side goes through the negative charge circuit to the other side. And when there is no negative charge on the first side, the battery drains.

When charging our device the negative charge travels in the reverse direction. It goes from the other side to the first side.

The area of ​​electrolytic can occur as long as they want to prevent the direct transmission of negative charge between the two sides.

charge controller:

The charging process is quite simple. Before going into fast charging, learn something about the charge controller.


Normal electricity is measured in watts, current in amps and volts in volts.

More current and higher voltage result in a decrease in charging time and lifetime.

Charge controllers are used to protect our device from fast spikes current. Lithium-ion batteries are typically measured in amps. A charge controller is used to control the battery during entering and going out.

The amount charge draws there are usually based on the type of software.


There are four types of USB versions. They are USB 1.0, USB 2.0, USB 3.0, USB 3.1.

USB 1.0 and 2.0 are typically only capable of up to 2.5 watts. And 3.0, with capacity up to 4.5 while the top end can reach 100w in 3.1.


USB PD known as USB power distribution is developed by the USB implementer platform. It has a capacity of up to 100watts.

Any manufacturer can use this USB. We can charge our iPhone and Pixel phones with it.

For iPhone, we have to spend a few more rupees for this. Because Apple will not provide its inbox. But in the case of Pixel phones, they are provided with an inbox.

Tech giants are more willing to sell their phones by advertising their charging speeds, but fail to add effects to it.

Nothing in this world comes without some form of effects and fast charging is not an optional case.

heat :

The heat incident occurs in the rapid process of transferring negative charges from one side to another. So the device may feel as if placed in an oven.

Life span :

As a result of heating, the battery life will decrease with respect to the increase. In watts. We cannot expect a big lifespan for those phones using this fast charging technologies.


And the transmission between the two sides is more rapid than the first, so the electrolytic area should be wider than normal so that from one part to another can be avoided when there is fast transmission. This affects the battery capacity.

Apple :

Brands like Apple are assured to update their customers for a period of at least 5 years if they use fast chargers like realme, oppo with 65w and 100 + watt reducing the lifetime of their phones Give.

Until now, he refused to use high watts in his charger and settled with a 10w charger in the bus box.


And to reduce e-waste they planned to get the charger out of their box … it could help normal iPhone buyers by reducing the need to buy a standard 10w when purchasing a phone.


Finally, if people want their phone to settle for longer periods of time with around 20w and below bus chargers … a relatively 30w charger can be reduced by 30% and a 40w reduction in lifetime over a year of 40w usage. Can reduce
