How to increase the autonomy of your smartphone?

The question that arises is: What can a user do?

One of the biggest concerns when buying a new smartphone and yours drums and consequent autonomy. Manufacturers still have a long way to go before they can present a device that does not have to go to the load after a few hours of use. The question that arises is: What can a user do?

To answer this question in a more informed way, let’s first revisit some concepts and notions about batteries smartphones, so we know what we’re talking about.

As with any type of battery, there is a flow of electrons that leaves one pole, feeds the equipment and then enters the opposite pole. Also, the battery must be connected to a higher voltage outlet to recharge.

If this worked in practice as in theory, there would be no problems and we would have batteries that would work for hundreds of years. Unfortunately, there are reactions and undesirable effects during the process negatively and gradually influencing the functioning of our battery. And for now we cannot avoid them.

Lithium battery problems

Before I start listing the things that don’t work, I’d like to reinforce that the batteries Lithium batteries are currently essential for smartphones and other low-power devices, as they are smaller and lighter than other technologies.

They can be constructed in such a way that they efficiently fill the spaces, they unload little when not used (5% less against 20-30% for others) and they don’t suffer from the memory effect, so we don’t need to load them to the maximum or wait for them to discharge to plug into the outlet.

That said, chemistry is not as safe as others. In fact, in addition to requiring several systems of safety mandatory inside, they have weak points and some tips can optimize their use.


The first problem of batteries lithium is the temperature. Every batteries they suffer from the heat, but lithium ones are particularly sensitive. One example is that people who live in colder regions have batteries that last longer than those who live in torrid regions.


In addition to the temperature, our batteries suffer a lot from the overload. I mean that if loaded with unofficial chargers and with very high currents, they can catch fire or explode. That’s why there are several protection circuits inside.

ADVICE: only use official chargers and do not leave your smartphone charging for more than 8-10 hours.

Full discharge

At batteries Lithium batteries can be irreparably damaged if they reach 0% charge. This is partly avoided by a system of safety It turns off the phone if the battery reaches 5% (indicating, however, that it is at 0%), but it is still dangerous to reach such low levels – it can die even if not charged.

ADVICE: keep a charge between 20 and 80%. As already said, these batteries do not suffer from the memory problem. It is even preferable to make more recharges that last less time than just one of longer duration.

inevitable deterioration

The biggest problem of batteries lithium is that, even if not used, they go through the process of deterioration, losing up to 20% of charge per year. This means that, even when preserved in the best way, after two years its capacity will be half, and with it the time operation of our smartphone.

ADVICE: don’t buy batteries reserve if not extremely necessary (in which case, keep them following the above temperature advice).

Tips to extend your Android battery life

Recapitulating the measures to be taken or avoided to optimize your battery life:

Finally, remember that after 2 or 3 years, maybe sooner, the battery must be replaced in order for the time of use may be satisfactory again.
