The batteries are one of the components of smartphones that biggest headaches gives manufacturers and if you ask Samsung that saw a problem with the Samsung Galaxy Note 7 battery echoed its launch. But the question that many of us ask ourselves is why the phone turns off before it runs out of battery .

The technology has evolved leading to batteries with a higher load capacity, faster charging times and even wireless charging without wires, but despite all this they continue to give serious problems.

Why does the phone turn off before it runs out of battery?

image If you've gotten here, it's because on more than one occasion you've seen how your mobile with 10% of battery suddenly shuts down only and without warning. This has an easy explanation, the batteries are composed of lithium ions, turning them into small explosive elements if certain circumstances exist. For this reason you can not introduce sensors inside the batteries that reliably show us the remaining charge.

To solve this, a statistical system has been designed using an algorithm that is responsible for calculating the remaining battery. This algorithm is responsible for showing the percentage of remaining battery in our mobile. The problem is that this algorithm becomes inaccurate in the long term, as the batteries age and deteriorate .

To all this, we have to add the functionality that many manufacturers implement to automatically turn off the device when low battery remaining values ​​are reached . This is done to maintain a minimum load that keeps the device's internal clock running.

All these measures are what cause your phone to turn off before it runs out of battery and I regret to tell you that there is no miracle solution, if your battery is discharged quickly, you have to buy a new device.
