How to test the performance of the Android charger?

If the charger is different, the charging speed of the Android device will change.If the charger has a problem, it may not be possible to charge at the speed according to the specification.

If you have experienced charging on Android devices, or want to measure the charging speed, please read the following:Tell us how to use Android devices to be charged properly.

Apps that optimize charging

Android has no function to check if the device is well charged.

So you need to rely on a third -party app.With Android 11, you can use simple functions to manage battery performance, and you can check the "Settings" "Battery and Device Care".

The Google Play Store has many apps that monitor charging.The most commonly used is "AMPERE" and "ACCUBATTERY".

I tested various charging apps, but these two are outstanding.Both apps support more than Android 5 (Lollipop).

Here, we will try to charge Android smartphones with Micro-USB and USB-C using Ampere.

Charging speed test

All you have to do is prepare a charger and insert it.Connect a charger that can be used safely to a wall outlet, personal computer, mobile battery, etc.

To measure all the performance of the charger most accurately, connect it to a genuine USB power adapter and insert an adapter into a handy outlet.

If you connect to a personal computer, you will get a different result, but I will explain it later.

AMPERE can check the charger and battery status in detail and measure how much power you are currently charging, so you can check the charging speed.

If you look at the image above, you will see what information is displayed.It takes about 10 seconds to measure a smartphone.The left side is the screen being measured.

If you purchase a PRO version, you can avoid displaying the ad at the bottom of the screen, but it is a fairly modest advertisement, so 1.It will not be enough to pay for $ 18.

In the Pro version, the icon indicating the charging level is also displayed on the status bar.

The color of the text is orange when it is not charged, and green when charging.If you are not charging, you will see how much the smartphone is currently using the battery.

The dark screen does not exhaust the battery than the bright screen (see below).When the screen is brighter, you use a lot of batteries.In addition, the application update in the background, Wi-Fi, and the strength of radio waves also affect.

The app itself is very simple and easy to see.

Tap the circular icon of the battery mark displayed in the app to open the Android "battery and device care" and display a detailed battery data.

When the number of amp is displayed negatively, the battery is used, so when it is displayed in plus, it is charged.

The amount of smartphone work is large (there are many background tasks, there are many open apps), and if you consume a battery than usual, you may get a low value when testing, but this is charged.It's not because of the bowl.

For example, if you charge 370mAh at 1,050mAh while consuming 370mAh as shown in the image, it will actually be charged at 1,050mAh -370mAh = 680mAh.

How much charging speed can be expected

Even if the charger is different, the charging speed when inserted into the wall outlet can be seen by looking at the power adapter label.

Somewhere in the USB power adapter, the adapter specifications will be displayed in label or small letters.The specifications at the time of manufacture are described in detail.

Check the value of "output".In this case, it is 1,000mAh.Therefore, you can expect a charging speed that deduct the amount consumed by the smartphone from 1,000mAh.

For this test, Samsung Galaxy A51, Samsung genuine high-speed charging adapter, and USB-C cable were used.I think your charger and smartphone are different from what we used this time.

But don't worry.If you use this app to find out that there is no value that should be obtained from the adapter specification, take the following measures.

To improve charging speed

If you do not get the expected charging speed, there is a way to increase the charging speed.

For example, if you use a smartphone in the cabin and turn off the screen during charging, the charging speed will be much faster.There are other ways to make the battery as long as possible, even if you don't do that.

Is your Android device properly charged?

You can test the charging status of Android devices by using third -party apps such as AccubataTerry or Ampere.

These apps display a number of batteries and charging, so you can analyze whether your smartphone is charged correctly.
