Fast charging technology allows us to charge the battery of our mobile phones in a few minutes. Given its advantages, it is not surprising that more and more manufacturers choose to include this technology in their devices. Currently, Many mobile phones have 100W or 120W fast chargingIt even reaches 240W in some cases (like the Realme GT 3).

Of course, it is important not to forget that it is also important to take advantage of fast charging. We need to use a charger with sufficient power: Otherwise we will not be able to make the most of the fast charging of the mobile phone. If you are not sure if the chargers in your home are compatible with fast charging for your mobile phone, there is an application that can help you find out.

Ampere allows us to check if we benefit from fast charging of the mobile phone

We are talking about Ampere, an Android application available for free on Google Play that can help us Accurately measure the charging speed of any chargerThe application is not only useful to know how fast our mobile phone actually charges; we can also use it to know the maximum capacity of the battery, its health status or the number of battery cycles.

The performance of the application is simple. To check how fast the charging is, we will have to connect mobile phone to power and open the appAfter a few seconds, Ampere will show us the milliampere with which we are charging, as well as the voltage of the charger used.

If the number at the top of the screen (milliamperes) is shown in green, it means: the device is charging properly. If it is negative and shown in orange, it means that the mobile phone is using battery (i.e. not charging). The second happens if your charger is not working or if you open the app without plugging your phone into power.

Before analyzing the information that the application shows us, it is important to be clear about the information about charging our mobile phone, which we can find in the user manual of the device. For example, the battery of the Pixel 6 that I used to test the application offers 30W fast charging.

It is recommended that you test the app when the battery is almost empty, as this is when the phone is charged using the maximum power available. As we commented, Ampere tells us the mA value we charge The device interface is listed at the top, and the voltage is listed below.

To calculate power in watts (W), we need to multiply the voltage in volts (V) by the current in amps (A). Therefore, We must convert mA to amps by dividing by a thousand.. When we have the equivalent value in amperes we can get the power (2050 mA/1000 = 2,050 A). In my case, 3.997 volts (V) multiplied by 2.050 amps (A) gives me 8.19385 watts (W).

By comparing this result with the information on the charger we use and the technical specifications of our mobile phone, we will be able to find out if the charger is suitable for charging the battery at the maximum possible speed. For example, if the Pixel 6 has a 30W fast charge and we charge it at around 8W, it would be better to use another charger.

APPLICATION Accumulating over 10 million downloads and has excellent ratings. Although it has some paid functions (such as Widgetsnotifications and alerts), the free version (with ads) is more than enough to learn more about charging our phones.
