Although many contemporary phones do not come with fast chargers, they may have fast charging capabilities.
There are several tests you can do to find out if your smartphone is charging as fast as possible.
How to tell if your phone is fast charging
Some phones make it easier than others by showing “charging fast” or “charging fast” on the lock screen.
Even if your phone doesn’t display this type of information, you can determine whether or not it’s charging to its maximum capacity in other ways.
Check for visual or audible cues

When charging fast, the Nothing Phone (2) , for example, displays the words “Charging Fast”, although many Android phones will display the same message.
However, instead of the single sound when you connect the charger, iPhones will now emit two “ding” sounds to indicate fast charging.
To find out how your phone indicates that fast charging is enabled, it is necessary to check the handbook or the manufacturer’s website as different manufacturers may use different techniques.
Use third-party apps

If your phone isn’t giving off a visual or auditory signal, you can still determine the speed at which it’s charging. Install Ampere on iOS or Android by going to the app store on your phone.
With the help of this useful program, you can calculate the wattage by measuring the incoming charging current and voltage. We’re using the Moto G7 Power as an example. A charger that can produce 5V at 3A, 9V at 2A or 12V at 1.5A.
We can get approximate values using Ampere which indicates that it charges at 5V and 3000mAh (very close). As a result, it’s charging the phone as fast as possible at 5V/3A, or 15W, which is why Motorola describes the charger as 15W on its website.
What is fast charging?
The phrase “fast charging”, which usually refers to faster than normal charging rates, is not well defined. Fast charging also depends on the phone, charger and cable used; There is no common standard or charger for this.
Qualcomm’s QuickCharge is supported by many Android phones, although its features vary. Some manufacturers like Samsung have their own features, such as super fast charging. But iPhones can also charge quickly.
Does my phone come with a fast charger?
You need to be aware of the wattage your phone can charge as well as the wattage of your charger to ensure that it is charging as quickly as possible.
By examining the label on the charger, you can determine its wattage. Watts equals voltage times amps, so if the output is 5V at 3A, the charger will be 15W. Divide the output (if specified in mA) by 1000 to get amps.
To find out what the maximum charging wattage is for your phone you will need to look up the exact specifications of your particular model online. If your charger’s wattage is equal to your phone’s maximum charging wattage, you have the fastest charger for your phone.

If not, you may want to consider using a higher wattage charger; Here are some top picks for USB chargers. Conventional charges typically provide 5W, while computer USB connectors typically provide 2.5W.
Keep in mind that even the best power banks available have different capacities, depending on the wattage available at each connector, when it comes to fast charging phones. If your charger lacks power, consider getting a good USB charger or power bank.
What about fast wireless charging?
The minimum wattage for wireless chargers that adhere to the Qi or Qi2 standards is often 5W, but many can offer 7.5W, 10W, or even 15W—although some phones can take advantage of higher rates.
Fast wireless charging, if supported by the phone type, is often slower than using a USB connection and a fast charger. If your phone isn’t compatible, there are still ways to add wireless charging to any phone.
Here are some of the best wireless chargers available right now for your consideration.
