Many new smartphones come with the fast charging feature. Unlike the preceding years, we
no longer need to wait for hours on end before we can recharge the batteries of our devices. Manufacturers nowadays boast of fast charging speeds and phones that could get charged in less than 30mins.
There are even phones that claim to get 100% charged in 20 minutes or less!

So, what is the fastest
charging phone? How does fast charging work? Let's take a look.


What Is Fast Charging?

As the name implies, fast charging is a feature that enables you to charge or
power your device in less time than you would for a normal
device. Fast charging entails sending more power into your
device in a relatively short period of time. In fast charging, the number of watts
(W) entering into your device's battery is increased.
The average smartphone receives about 2.5W to 6W
while charging from its USB port. Fast chargers raise that
amount about 10 times, with
some phones heading towards 240W! You should note that
not all phones support fast charging and that all chargers
aren't fast chargers.

For fast charging to work, you need a charger and a phone
that supports fast charging. So, if you use a fast charger on a phone that doesn't support fast charging, or doesn't have the fast charging features, it would charge at normal speed. The same thing happens when you use a normal charger on a fast charging phone—your phone
gets charged at normal speed.

How Does Fast Charging Work?


Watt is the SI unit for Power. Power is the product of the
current in amperes and the voltage in volts. Increasing the
current or voltage also
increases the power that flows through the charger and into the device. In fast charging, either the voltage or current is increased—while the
other stays put.

When the voltage increases, the device heats up faster
while thicker cables are needed when the current is increased instead.

Different companies have their fast
charging techniques. Some of them include:

¤Qualcomm (Quick
Charge)


¤USB Power Delivery.


¤OnePlus (Dash Charge).


¤Samsung Adaptive Fast Charging


¤Huawei’s (Super
Charge)


¤MediaTek (Pump
Express or PE)]


¤OnePlus Warp Charging

What Is the World’s Fastest Charging Phone?

The fastest charging phone right now is arguably the Redmi Note 12 Explorer from Xiaomi, which comes with a 210W maximum charging speed. It's
4,300mAh battery can fill up from 0-100% in around 9 minutes.

A close runner-up is the iQOO 10 Pro that comes with a top
charging speed of 200W, which is advertised as enough to juice up the phone from 0-100% in about
10 minutes.

Of course, i can't forget to mention OnePlus here too, as the OnePlus 10T supports 160W and
with the SuperVOOC charger.

The upcoming GT Neo 5 by Realme will support 240w charging speed, 0 to 100% in 10mins.

incredible, I did like to see the impact of fast charging features on the over all health of a battery life cycle as against conventional 5watts - 45watts chargers

Let's look at Xiaomi 200W charging. The 200W HyperCharge tech needs a charger that can support the speed and a phone that can handle the extra power. That is to say, it’s up to the user to decide whether
to use the 200W charger or a regular one. The faster charger will require a separate purchase (for some company it comes in side the box). Using the 200W power only in emergency situations might help save the phone’s battery health.

When asked about battery health degradation related to the new charging speed. Xiaomi answered that the battery capacity would drop to 80% after 800 charging cycles at 200W.

So you might have to think twice about using 200W charging
frequently.

Xiaomi said that its findings are better than the current
regulations in China that say smartphone battery life should
degrade to 60% only after at least 400 cycles. That’s an
incredibly low bar for battery health.

Oppo also confirmed that its 40W battery charging tech degrades the battery health to 70% capacity in the same number of cycles that 15W needs to lower the maximum capacity to 90%.

My advice is to get maybe a normal 45w to charge the phone as normal and only use the 120w in emergency situation like when your neighbour on gen for 20 min to pump water

omo, I'll just stick to a minimum of 18watts & be enjoying fast charging while counting down on my battery cycle count 😀.

Educative

My redmi 11 pro + 5 g charges from 1-100% in less than 20 minutes when the fast charge is activated.

Very educative......... My Samsung A50 charges from 0 -100% in 1hour:20minutes...

It uses 120W PD3.... GsmArena said 0-100% in 15mins. But note there is difference between 100% and full charge.

Btw, how many hours of screen time do u get on a full charge?

I've been using OnePlus 7 since 2019. Battery life is still very good.

yes, though its not the original follow come Samsung charger, the original take me only 60 minutes, but it has spoiled.

Interesting, thanks for the feedback, what wattage of charger do you currently use anyway?

ohh.... You for just close eye buy the original

Yeah i just read it, but the 300w is for a "modified" note 12 discovery. The technology is yet to be released out yet. Maybe for upcoming models. Even the note 12 discovery with 240w is for china only. So they might equip their new phones with this 300w
