Do you have less and less battery in your mobile? The fact that the battery capacity gradually decreases over time is normal. But if it has lost too much in a short time, then it is very likely that what you need is a recalibrated. In general, sudden blackouts, or power outages in our device, are due to a poor battery calibration of the mobile, consequence of the use we make of them. To solve these problems, we give you some little tricks, and we talk about Battery Calibration, an ideal application for these cases.

The use we make of mobile phones means that, in the vast majority of cases, we are not taking advantage of them in the correct way. We think that because it is from Lithium, It does not matter if we charge the battery when it still has half left, or if we disconnect the charger halfway, and the truth is that the battery does not lose too much by these actions, but after a while, it begins to have reading failures thereof.

Common failures are usually sudden restarts, after which the battery of our mobile phone has mysteriously fallen. The casual blackouts when I had a lot of battery. Or the shutdown when he still had left about 10% as if this is already over. All these errors occur because the mobile is not capable of read battery information, nor know the capacity you have at all times. Sometimes this also occurs after installing a new ROM, so whenever it is done it is advisable to calibrate the battery.

To do this, we need to be Root, and have permissions of Super user. First, we totally download Battery. Once the mobile is turned off, then we try to turn it on again. The normal thing is that it still has battery left, and for that reason, we turn it on and let the reserve it contained discharge. Once this is done, we plug in the mobile and let, while off, charge 100%. When it is complete, we unplug, turn on the device, and plug it back in, so that it charges a little with the terminal on. Meanwhile, we install Battery Calibration, we start it, and click on the button that has the same name.

With this, we will have already achieved that our Android takes that point as that of the Maximum capacity battery. In addition, it takes care of delete file old that contained the battery information, and generate a new one with the correct data. Battery Calibration can be downloaded from Google Play for free. Although we can only use it if we have Root permissions, if we do not have them we can follow the loading and unloading procedure mentioned. The more cycles we carry out like this, the better results we will obtain and the better the battery will work.
