How can I calibrate Samsung Galaxy J7 (2016) battery?

Answer 1

Method 1: general

The first method is pretty generic and simply need our mobile and charging cable.

1. Charge your mobile with a wall charger and the terminal on.
2. When is loaded to 100% disconnected from the wall and turn off the phone.
3. Off we go back to plug it into the wall until mark a 100% load.
4. When reaches 100% turn it on and use as normal until it turns off completely.
5. When you run out of battery and plug it goes back to the charger d epared until it reads 100%.

Method 2: With the app CurrentWidget: Battery Monitor without Root

If the first method does not work we can try this app.

1. We consult our battery capacity. We can see in the box, the official website ...
2. CurrentWidget downloaded: Battery Monitor Google Play Store.
3. Activate the widget like any other widget in Android.
4. Mobile charge until the widget tell us that is 100% and the mA look that tells us.
5. By unchecking the same amount of mA indicating the box or leave it plugged manufacturer until you check.
6. When dial restart the phone.

Method 3: With the Battery Calibration app with Root

If we have made root access to our mobile Android we can also try Battery Calibration.

1. Install the Battery Calibration app from the Google Play Store.
2. Mobile plug the wall charger.
3. We open the app and give SuperUser permissions.
4. We hope that the number of mV indicating the app stops increasing, whether branded or not 100%.
5. When that figure has stopped press the Battery Calibration option.
6. Restart the phone.

Method 4: Recovery with the Custom Root

Finally, if you do not want to use applications have root access but we can calibrate our battery with a few simple steps.

1. 100% loaded the phone with a cargdor wall.
2. We enter Recovery mode.
3. Wipe battery stats select the option that it does is delete the file battery stats.
4. We return to the main screen and restart the phone.

After using any of these methods it is advisable to make several full charge cycles, ie, let the battery drain completely and when we connect to the outlet does not disconnect until it reads 100%.

Comments

I have a doubt in the first method of SIN ROOT; The battery capacity of my smartphone is 1700 mAh, at that capacity is concerned? Would the widget have to show that amount? :)

This figure is probably correct, effectively the battery capacity is the number with mAh, what model is your phone?

It is an galaxy j7, I tried the first method but the widget showed values that oscillated when pressing on it, I was not very clear how to use the application to do the calibration: /

As I see, the capacity of that model is 1750mAh
As I understand it, the widget shows you the current charge of the battery, and this value will oscillate by the natural use of the cell phone. You must leave it loading until you reach the number that should have your mobile, 1750 in this case, then shut down and restart.
I have not tried the widget personally, although I find it a little strange that those steps are enough to calibrate a battery
