The happy battery of the iPhone, although little by little it is improving, and even the Plus devices show a more than exceptional performance, there are still many users who the autonomy of the iPhone is insufficient. But this is not all, and it is also possible that the iPhone turns off when according to the indicator it still has a battery. This is an addition to the instability of autonomy that can make us lose patience. Nevertheless, en Actualidad iPhone We teach you how to solve the error that causes the iPhone to turn off when it still has battery.
The first thing we can do is calm down and perform what is known as a "Hard Reset", To do this we will press the Power button and the Home button for 5 seconds, the iPhone will turn off and start automatically. In users of the iPhone 7 in any of its variants, as it does not have a physical Home button, they must press the Power button and the Volume button down to restart the device.
If one day after performing this Hard Reset our battery has not returned to normal, we must first make sure that we are running the latest stable version of iOS, once updated we will make a full charge to the device. Now we will take care of using it until it turns off, but it will not remain here, when it turns off we will try to turn it on, and so on constantly until it does not do it anymore. Now, We will put it to charge, and when it starts automatically we will put it in "airplane mode" and we will not use it until it reaches 100% of the battery, when we will disconnect them and check if we still have the problem of premature shutdown.
If none of these solutions take effect, we will have to restore the device through iTunes, in this way it will be returned to calibrate iPhone battery. But it might not be enough, if it continues to fail it means that we have a hardware defect in the battery, so We will contact Apple for a replacement or repair solution.
Yes, this is known as calibrating the battery of our Smartphone or IPhone. This happened to me that it was turned off at 15% and I tried doing this and the truth is that now it lasts up to 1%.
