Applications to know the status of your battery are very useful to keep an essential component for your phone under control, but with the hodgepodge of fast charging on the one hand and that more and more phones come without a charger and we have to recycle some of those we have at home (but then they may not be compatible), the result is that sometimes we do not take advantage of the fast charging of our phone. Brands, models, amps and voltages are a recipe for disaster… until Ampere came to my Android phone.
So if like me, hopping between three houses with a laptop, two phones, and a few cables, you want take advantage of the chargers at home to get a stable charge and as fast as possible for your mobile, try downloading Ampere (available for Android only). Note: although there is a paid Pro version, the free one is enough for these tasks).
How ideal is this charger for my phone?
It is important to keep in mind that although more Watts invite you to think of a faster charge, that does not mean that it offers the best results. Although with Ampere you can know the state of our battery and for that alone it is already interesting, it also indicates the exact voltage, the real maximum capacity, allows you to configure alerts when it heats up and what interests us most for this application scenario: knowing the power of charge in mAh that is entering it. Because we are going to use Ampere as a power meter for the mobile (so we save buying the device).
The next step is know the information related to the charging of your phone, something that you can find both in the manuals, websites with the specifications or in the Xataka analysis. In my case it is a Samsung Galaxy A71, with load at 25W. Its original charger offers an output voltage of 5.0 V – 3.0 A or 9.0 V – 2.77 A. It will help you make comparisons
Now grab that charger you have at home and charge your phone. Ideally, your phone have battery low enough to draw more accurate conclusions.
At that moment open the Ampere application and leave it running so you can see how the energy measurement evolves at the top (at the bottom you will find the data on the status of your battery that we mentioned earlier).
Ampere displays a milliamp (mA) value at the top, where we’ll see the minimum, maximum, and average load number. And now it’s time for some basic math: Watts is the product of Volts times Amps. (physics formula of the urged: Power = Voltage x Intensity). To simplify the calculation a bit, you can round the units and don’t forget to go from mA to Amps (dividing by a thousand).
With the numbers done, Compare the Watts data with the specifications of the charger and your Android device to know the performance. So, if you are charging at 10 but the phone is designed for 25W charging as is my case, there is room for improvement. As an approximation, standard fast chargers show data that is around 3000 mA compared to 1000 mA for slow ones. Another interesting fact: with Ampere you can see the download times as you use the phone, interesting to appreciate those applications that eat up the battery.
On the other hand, the fact that the range between the maximum and minimum intensity recorded is wide means that the charge of that charger does not stand out for its stability.
