Hi Mi Fans,
In the present trend, smartphones are the alien devices running our lives from the morning till night. But, what runs these smartphones? ‘Batteries’. Our topic of interest for today is targeting the technologies which are exceptionally made to improve the charging style of smartphones.

Fast charging has taken over the running trend of conventional chargers. What exactly is this fast charging and technologies related to it? Should you buy a fast charger for your smartphone? Let's get into details.

Fast Charging :-

The fast charging technology basically charges your phone faster than a conventional charger would do. You normal charger will charge your phone at a specific amount of voltage and current that it can take load of. This specific amount of voltage and current then passes from your charger through the phone circuit to charge your phone’s battery.

Fast charging is different and better as compared to conventional chargers. Fast charging enables the current to fluctuate as per your phone's needs. It’s a process of supplying the current demand to acquire a better charging speed.

How Fast Charging Works :-
Before we dive into the weeds, let's start with the fundamentals.
Every smartphone has a battery, and every battery delivers power in more or less the same way.

Cells consisting of two electrodes (one positive and one negative) and an electrolyte, catalyze reactions that convert compounds into new substances. Over time, ions -- atoms with too few or too many electrons -- form in the electrodes, driving a flow of electrons to the battery's negative outer terminal and supplying your phone with an electric charge.

In non-rechargeable batteries, those chemical reactions occur only once. But in the rechargeable lithium-ion batteries that power smartphones, the reactions are "reversible." When the battery discharges, the chemical reaction produces electricity, and when the battery recharges, the chemical reactions absorb power.

Quick Charge Technologies :-
Quick charge technology is brought to you by Qualcomm. Quick Charge 1.0 was first introduced in 2013 which was able to charge your phone 40% faster than the usual phones. This was then deployed and used in all the Snapdragon based devices. As at present we have reached an advanced version of Quick Charge Technologies, let’s hop onto to its newer versions.

Quick Charge 2.0 :-
Explaining Quick Charge 2.0 in simpler words; it lets more power to enter and do the charging honors without harming your battery or phone’s charging circuit with its power controlling regulator. With the use of 9 volt, 2 amp of power it will take your battery from 0% to 60% in 30 minutes.

Quick Charge 3.0 :-
Although it doesn’t differ from what is offered in 2.0 but, the criteria is applied again. It regulates and manages to push in more power than the older version. Which means Quick Charge 3.0 can choose between wider ranges of voltage with its Intelligent Negotiation for Optimum Voltage (INOV). This allows 3.0 to charge faster for an efficient battery run, taking your battery levels from 0% to 70% in 30 minutes.

Quick Charge 4.0 :-
Qualcomm has now introduced it latest flagship Snapdragon 835 which is packed with features along with Quick Charge 4.0. It is 20% faster and 30% efficient. With Intelligent Negotiation for Optimum Voltage (INOV) it also has real-time thermal management helping the power supply to stay cooler for safe battery charging performance.

It has the capacity and dynamic to take your battery from 0% to 50% in just 15 minutes. Qualcomm has quoted its new release by saying it as 5 for 5, which means 5 hours of battery life in 5 minutes. It doesn’t stop here, the innovation in the newer version; Quick Charge 4.0 goes on and on.

Should You Buy A Fast Charger :-
You can buy a fast charger if you know the technology used in it is compatible with your phone. If your charger has quick charge technology and your phone doesn’t, it will heat up your phone and can harm the current passing chip located in your device. All of this can slowly damage you battery performance and your phone as well.

In a potential phone, normal charger won’t harm the battery or phone but it won’t affect the charging speed as well. If you want to know if your phone supports Quick charge technology or not, you can consult Qualcomm’s website, Click Here.

Conclusion :-
Fast charging technology is a blessing to smartphone world. As we see more and more features being added to smartphones, charging facility is also being developed alongside. Fast charging has definitely added up to fast and efficient use of chargers and phone batteries. It also has developed a new era which is enabling the travelling time period less dependent on power banks and power supplies. You can spend less time on a charging station and can have hours of battery life to use while travelling.

Thank you

Some of the outlets in your house are likely 20 amp outlets , wired with 12 evaluate cable as shown at Essay Help UK forum. Others are 15 amplifiers, wired with 14 evaluate (smaller) cable. Will a 100 watts lamp attract more present, hence more energy, hence give more mild, on a 20 amp store vs. a 15 amp? Of course not. The store provides 110 to 120 v, mild bulb has an effective level of resistance when running up a little more than 100 ohms, causing in a little less than an amp of present and so a energy use of 100 h. However much present the store can supply, as long as it's at least as much a the fill requires
