How to charge the mobile phone to maximize battery life

We will explain how to charge your mobile phone maximizing battery life , so you can slow down its degradation. The batteries in your mobile have a fork of 300 to 500 charge cycles, from which its performance begins to degrade and the maximum energy it supports begins to reduce.

Each time we make a 100% battery charge, a battery cycle is completed, although one day we make 25 and another one 75, and if your mobile batteries have a fork of 300 to 500 charge cycles, this can do After two years, the health of the battery begins to suffer . This is normal, although there are some practices that lead to faster degradation that should be avoided, and some tricks can also help you maximize this lifespan.

Try to keep the battery between 20 and 80% charge

There are several studies that suggest that keeping the battery between 20 and 80% charge is beneficial for its life. Other studies state that it is even better to keep it between 40 and 80% – and even going to the extreme, between 40 and 60% -, although the golden rule is to keep it between 20 and 80%.

When the charge rises to 80% you will be forcing and degrading the battery ion cells, which means that your health suffers and autonomy decreases over time. The same happens when the battery goes down 20%, which we will be forcing. Therefore, by keeping it within these limits, what you are going to achieve is not to put so much stress on the batteries and prolong their life.

Maybe once a month it is good to discharge the battery completely and charge it 100% to synchronize the battery indicator of the operating system, but nothing more. By doing this, we will ensure that Android or iOS always shows the exact percentage of charge that the battery has left, but it is not something we should abuse.

How to keep batteries always between 20 and 80%

The big question is how to always keep that charge on your mobile. IOS users have it easier , since one of the novelties of iOS 13 on the iPhone has been a system that makes the night recharge stop at 80% to, through artificial intelligence, estimate the time at that you disconnect the mobile every morning and prepare it to be 100% charged when you wake up and need your mobile. Thus, it will not exceed 80% more than in the end.

On Android mobiles, the thing is very complicated, because you will have to root your mobile and install third-party tools such as Magisk Advanced Charging Controller , a program with which you can set minimum and maximum upload and download limits. It is used from the terminal, but there is a graphical interface for this tool called AccA .

There are also other options for which you will also need to have the rooted mobile, such as Battery Charge Limit . There are also other applications without root that do not limit the charges, but they do notify you when the limits you want are reached to start charging or stop doing it, such as Battery Charge Notifier .

It’s not so bad to leave the phone charging all night

In any case, you also have to know that lithium-ion batteries do not have the memory effect of other old battery types. This means that if we charge a 100% battery before it has been discharged, its long-term capacity will not be reduced , since they are prepared for these behaviors.

Nor is there any danger of leaving the mobile charging overnight , since new generations of lithium-ion batteries or lithium polymer do not suffer from having them for long periods connected to the current to charge them. In many cases, the batteries simply disconnect the input flow when they detect that they are already 100% charged.

Only if that charge is reduced will the battery charge be activated again, but it will do so in small intervals that allow for example that when we get up we have the mobile charged to 100% but also without it being hot as it could happen if we take the device as soon as that level is reached.

By this I mean that it does not imply an extra degradation, although as we have seen in the first points, you would have the degradation that involves continuously charging the mobile to more than 80% . Although this no longer has to do with the fact of charging it all night or not, but with the percentages of loading.

Keep your cell phone’s battery calibrated

The operating system of your mobile uses a series of internal algorithms to calculate the percentage of battery you have at all times. These percentages today are usually quite reliable, but you can always do things that unintentionally affect your calculations and fail slightly, so that they do not calculate the percentage of remaining battery in a completely correct way, being uncalibrated . Therefore, once a month or every few months it may be useful to calibrate the battery .

How to do it depends on the operating system. Apple offers very precise instructions on how to calibrate the battery: first you have to charge the cell phone battery 100%, and then discharge the battery completely until it turns off when it reaches its limit. Then, let the mobile stand 6 or 8 hours before charging it to end the residual excess battery that may be present, and recharge the mobile for another 6 or 8 hours with the device turned off.

In Android there are no methods imposed by manufacturers, but in general you can do a process very similar to Apple with everyone else. First charge the battery fully, and after making sure you do so, charge it until it automatically turns off. Let the mobile stand for 4 hours in case there is any residual excess battery, and then charge it again with the mobile turned off. Wait until it is 100% and leave it a little more just in case.

Try to prevent the battery from overheating

Another important tip to take care of your cell phone battery is to prevent the battery from overheating , since heating reduces its performance and shortens its life. For example, if you see that playing a particularly demanding game, everything starts to warm up, it may be better to take small breaks, and especially take it into account when using it continuously.

If, for example, you travel by car while using a map application to navigate, be careful if the mobile phone directly gives sunlight through the windshield, as it can cause it to overheat with almost total safety. Ideally, in cases such as this one, look for a space where you don’t get direct sunlight inside the car.

Obviously, you should not leave it exposed to the sun even if you are not using it. Therefore, be careful to leave it in direct light when you are at the beach or the pool, and also leave it in the typical car seat where it always gives light. Nothing will happen to leave a few minutes, but especially on hot days try not to leave it in direct light.

This also applies when charging the mobile battery , for example, not allowing it to charge on a small table or other place where it is giving direct sunlight. Or even on the beach, if you carry a portable charger, do not leave it in full sun.

Use the original chargers whenever you can

And we end up talking about the chargers. Each usually has very specific characteristics, something that manufacturers rarely mention, which makes people end up overlooking. Therefore, it is advisable to use the charger that comes with the mobile whenever you can, and above all, avoid using those cheap chargers of doubtful quality that you can find in many stores. They can serve to help you in specific moments, but do not abuse them.

In the case that you have to buy a new charger and you cannot get an original one, look carefully at the voltage and intensity of the original charger or that the mobile phone supports, which will appear in the instruction booklet, the device box, or the Charger with the letters V for voltage volts and A for intensity amps.

It’s not like it’s going to be something that damages your battery so much, but it’s going to help you have a much faster and more optimized charge . You will also have the assurance that the materials and construction of the loader are correct and there is less chance of any damage.
