Fast charging has become one of the areas of most innovation in the smartphone industry in the last few years.
Smartphone manufacturers out of China have pushed higher and higher charging rates so that now we have reached the point where you can charge a flagship phone with a big battery in just half an hour. This deals away with the need for nightly charges and is a huge convenience. Needless to say, this one feature has become an important criterion in picking up your next phone, especially for the most demanding users. However, we should also mention that super fast charging may come with some cost to the long-term battery longevity.
Below, you will find the fastest charging phones out there along with a few details about the technologies used by each of the companies making them.
Which is the fastest charging phone in the world?
The Vivo iQOO 7 holds the title of the fastest charging phone in the world so far in 2021. The phone features 120W fast charging speeds and its 4,000mAh battery recharges fully from 0 to 100% in just about 18 minutes.
Phone charging speeds by brand
Below, you will find the supported charging speeds for all major phone brands.

iPhones Fast Charging Explained
However, starting with the iPhone 12 series, Apple no longer includes a charger in the box and you need to purchase one separately. Apple is selling its own official 20W USB-C Power Adapter for around $20, and you will also need a USB-C to Lightning cable if you don’t own one.
Can you use a third-party power adapter that is not made by Apple and still get those fast, 20W charging speeds? The answer is mostly yes, but make sure that the adapter you purchase supports the USB Power Delivery (USB-PD) standard. For example, a standard Samsung phone charger also supports the same USB-PD standard and will also deliver a fast charge to iPhones safely. You also have numerous third party options with names like Anker being among the most reliable brands.
Samsung Galaxy Fast Charging Explained
Interestingly, the latest Samsung phones (including the S21 Ultra) don’t support the 45W fast charging speeds that Samsung introduced with the Note 10, and instead max out at 25W. Samsung will not officially confirm what’s the reason behind that, but long-term battery preservation might be one possible reason.
Earlier Samsung phones like the Samsung Galaxy S10 Plus, S10 and S10e only support the Qualcomm QuickCharge 2.0 standard and they max out at charging speeds of 15W.
Google Pixel Fast Charging Explained
Can you use a faster 25W or 45W power adapter to charge Google Pixel phones even quicker? The answer is no, the phone is configured to receive a maximum charge of 18W so you won’t see any benefit from plugging it to a more powerful charger.

OnePlus Fast Charging Explained
What this means is two things: one, it is a proprietary solution which means that you need to use the OnePlus charger with the OnePlus cable to make use of the fastest charging speeds (thankfully, both are provided for free in the box), and second, it means that other chargers like a USB Power Delivery charger will not be able to deliver its maximum output on OnePlus phones.
In reality, we have found the proprietary OnePlus charger to work extremely well and one advantage it has over other technologies is that it is able to maintain the fast charging rates even while you are using your phone. On other phones, in contrast, charging rates drop noticeably if you use your phone while charging.
Huawei Fast Charging Explained
Can you use a third party power adapter with Huawei phones? The answer is yes, but don’t expect to get the same fast charging speeds.
Oppo and Realme Fast Charging Explained
Chinese company Oppo is not popular in Western markets, but its budget off-shoot Realme is picking up pace in many places across the globe, and one of the key selling features is a super fast charging rate.
The technology is similar to what is used in OnePlus phones (which are part of the Oppo group of companies). It’s called Super VOOC 2.0 and it uses pumps up power at a rate of 10V and 6.5A, and it also uses GaN technology to achieve that in a relatively compact package.
This charger, however, will only work with few very specific phones and will charger other phones at a rate of just 10 watts.
Xiaomi and Redmi Fast Charging Explained
The charger provided in the box also supported the QC4.0+ and Power Delivery 3.0 standards, so it is technically compatible with many other phones as well.
