Fast vs Fast vs Fast Charging: Comparison


All premium and mid-priced mobile phones come with fast charging technologies. Different brands call these by different names and from a customer’s perspective this can be a bit confusing.

This article is about explaining different fast charging techniques such as fast charging, fast charging and dashboard charging.

What is fast charging?

It is a licensed Qualcomm technology that works with all flagship phones that come with Snapdragon Android. It is recommended to use a power adapter supplied with the handset to use the fast charging feature as efficiently as possible.

Any suitable third-party adapter will also work. Other than that, if you use a different adapter, charging will take place at a normal pace.

The technology works on the idea of ​​maximizing the transfer of the phone’s charging while also making the phone work efficiently while charging.

What is fast charging?

It’s the same technique that fast charging uses. It is a marketing gimmick used by smartphone manufacturers and because of that, the customer can get confused between fast charging and fast charging.

Fast charging maximizes the phone’s charging power while the handset operates efficiently. There will be an improved version for the same, also called Quick Charge 2.0. This allows the phone to be charged with a power of 36 Watts.

The high alternating current from the socket is converted into the amount on which your device can be safely charged.

The current drawn from the outlet varies from device to device, but normally it draws between 1-2.4 amps.

The more current that is drawn, the faster the charging will be. The latest Quick Charge available is Quick Charge 5, read more about it on the Qualcomm website

So when choosing the handset, keep in mind that the device may draw more current, which will lead to faster charging.

What is fast charging?

Fast charging is a feature supported by some modern phones and tablets that start it up in a very short time. The reason many devices take so long to charge normally is the limited amount of power they can absorb at one time; typically five watts or less.

This is a design choice that keeps production costs down for standard wall warts and also ensures that the relatively small batteries in mobile gadgets won’t fry from overloading with too much current.

The charging process

You may have noticed that your phone charges at a higher rate initially and then gradually slows down. There are 3 stages in charging:

Phase 1: Constant current: as the voltage increases to the maximum threshold; the current remains constant. This is the stage where the power is delivered to the phone quickly and thus the maximum charge in less time.

Stage 2: Saturation: This is the stage where the voltage has reached its peak i.e. the maximum threshold point and now the current drops instead of remaining stable.

Stage 3: Trickle/Topping: This is the stage where the phone’s battery is fully charged and there is still power, the power will periodically charge a low ‘topping’ amount as the phone consumes the battery.

This particular standard is set for charging the phones so that the phones overheat and can explode. Different manufacturers have adopted this technology and given it different names. The basic idea is the same with different techniques to achieve the same result, which is fast charging. For example:

Qualcomm Quick ChargeSamsung Adaptive Fast ChargingOnePlus Warp ChargingOppo Super VOOC Charging

What is adaptive fast charging?

This is the fast charging technique available in Samsung handsets, especially the Galaxy series. With this technique, the maximum power that can be drawn is 18W.

Best of all, it knows when the battery is fully charged and the power turns itself off even when the phone is plugged in; hence the name ‘adaptive’ to it. It automatically changes the charging speed so that the battery lasts a long time.

What is supercharging?

This charging technology was introduced by Huawei. This charging technique is compatible with Huawei and Honor handsets. The basic idea is that it optimally alternates voltage and amps while charging. The handsets have an integrated power regulator chip in the phone that does the magic.

What is Dash Charge Technology?

OnePlus phone comes with dash charging technology. The Dash charging technology was originally created by OPPO. The idea of ​​dash charging technology is that it doesn’t increase the voltage, rather it draws more current which is drawn through a thick charging cable that draws more amps at a time.

The system uses an 11 Voltage charging connector that draws 5 Amps of current. It can provide a maximum power of 55 Watts. This offers faster charging compared to the fast charging technique. This is a really smart choice as you can use the phone while it is charging as the phone does not heat up.

What is the VOOC rate?

VOOC ie Voltage Open Loop Multi-step Constant-Current Charging is a fast charging technology introduced by OPPO† The VOOC flash charging circuit lowers the temperature of the charging adapter and creates an interface between the phone and the adapter that maintains charging speed and charging safety. It can consume up to 50W of power to enable fast charging in their phones.

Rapid vs VOOC vs Quick Charge: Which is the Best Charging Technology?

Rapid vs VOOC vs Quick Charge: Which is the Best Charging Technology?

The simple logic behind how fast the phone charges depends on the amount of voltage drawn.

A major problem with the greater amount of voltage being drawn is that it leads to heating of the battery and makes it volatile or drastically shortens battery life. Most phones nowadays allow us to charge quickly.

When we talk about fast charging, we think of 3 major technologies, fast charging, VOOC charging and fast charging.

These 3 fast charging technologies use different techniques to charge our phones faster.

The most popular and widely used technology is fast charging because there are many accessories that support fast charging. Though the charging speed is slower compared to VOOC, but due to the availability of truckloads with compatible accessories, it is one of the most widely used fast charging technologies.

The fast charging is also USB-PD compatible, which means that USB-PD compatible phones can use a fast charging cable and vice versa.

VOOC charging technology.

This technology produces mild to moderate heat because the voltage regulation is done inside the phone. What the VOOC charging technology does is regulate the current and this regulation is done through the adapter and not the phone, which reduces the heating of the battery. But one drawback is that you cannot use a VOOC charger to charge non-compatible phones.

In conclusion, VOOC is undoubtedly the best fast charging technology available in the market today. It charges the phones the fastest compared to the other fast charging technologies available today. It does not heat the battery very well, so the battery life of the mobile phone is longer compared to fast and fast charging.

Some frequently asked questions:

What is the difference between Qualcomm Quick Charge and Oneplus Dash?

The idea of ​​Oneplus dash charging technology is that it doesn’t increase the amount of voltage, rather it draws more current drawn through a thick charging cable that draws more amps at a time.

The idea of ​​Qualcomm Quick Charge is that it draws a lot of current while preserving the number of Amps used. Dash Charge technology provides faster charging compared to the Quick Charging technique.

Are fast charging and fast charging the same thing?

Yes, they are the same with brands doing the marketing gimmick.

Which is better: super fast charging or fast charging?

Super fast charging is disabled by default, even if the handset supports it. The reason is that it draws a lot of current which can hinder battery life. Super fast charging uses 25W-45W while charging and fast charging consumes 15W of power. It depends on the adapter you are using.

Which is better: fast charging or slow charging?

Fast charging and slow charging, both have their pros and cons. Fast charging can charge your battery in minutes, but the power can get warm and freeze if you try to use the phone while it’s charging.

Also, the battery life may not last long as compared to the slow charging batteries. The downside of slow charging is that it charges the battery slowly and in the world where the phones offer a 5 minute battery charge, it is in high demand to work with slow charging batteries.

Are VOOC and dashcharge the same?

Yes, it’s the same. The technology used is the same. It is called VOOC charge in OPPO handsets and Dash Charge in OnePlus handsets.

Dart charge vs VOOC charge. What is better?

Yes, it’s the same. The technology used is the same. It is called VOOC charge in OPPO handsets and Dash Charge in OnePlus handsets.
