The battery in your smartphone: a little about proper operation

Based on materials from

Your smartphone is a real miracle of technology, a powerful computer in a small case that can handle a huge number of tasks. But all his power is instantly reduced to zero when his battery is running out. A removable battery is becoming less common and therefore the question of how best to take care of the battery in your smartphone is becoming more pressing. Fortunately, it is not that difficult to successfully save its resource – it is only important to follow a few simple rules.

We will not talk about the simplest rule 'do not kill the remaining charge for toys and finally turn off unnecessary GPS and Wi-Fi, if the phone's' power 'is running out, and you desperately need it for the next hour.' But the recommendations below are quite capable of helping you maintain the health of the battery worker.

The battery in your smartphone: a little about proper operation

Maintain an optimal charge level

You may have heard something about the 'memory effect' of the battery. The fact that if you do not 'train' the battery, charging it completely and discharging it to zero, it will lose some of its capacity. Forget it when applied to your smartphone.

Battery 'memory' is a reality, but this applies to nickel-based batteries, and lithium-ion in your device should be handled slightly differently. More specifically, recharge when you have the opportunity.

In order to maximize the life of such a battery, you need to keep it more than half charged for the maximum time. But a full charge and then a discharge to zero will not allow anything good to be achieved, moreover, only harm if you repeat this often. A full charge and discharge about once a month for calibration is quite enough. Of course, if you constantly bring the battery to the limit values, it will not cause it to explode or anything, but it can shorten its life.

You cannot keep the phone on a charge all the time, because the battery overheats. Fortunately, the charger is smart enough to stop charging when the battery is fully charged. Moreover, it is harmful for the battery to be fully charged all the time. Therefore, it is best to remove the phone from the charge before it reaches 100%, and you should not leave it when it is already charged.

Let's summarize. If you want to extend the life of your smartphone battery, try to keep the charge between 40 and 80%. Better several such cycles per day than completely emptying the battery and then charging it fully.

Keep cool

Now that we have dealt with the problem of sub-optimal charging, we can begin to fight the enemy, which is much more terrible than her. It's hot. Your battery degrades much faster in heat, no matter how actively its resource is used.

At an average temperature of 0 ° C, a lithium-ion battery loses 6% of its capacity per year. At 25 ° C this number rises to 20, and at 40 degrees it reaches 35%. This doesn't mean sticking your phone in the freezer – just don't leave it in an overheated car or similar.

Avoid wireless charging

Wireless charging is an advantage for a modern smartphone, but it also comes with a cost. Current induction wireless chargers have a big drawback – they generate heat. Heat that literally roasts your battery. Nothing good about that. Regular wired charging is not as convenient, but it is much healthier for the battery.

Avoid death from starvation

If you are going to leave the lithium-ion battery for a long time, it is better that it retains about 40% of the charge, and then it will not discharge to zero. Li-ion batteries do not 'drain' of energy until they are used, unless they lose 5 to 10% per month.

But discharging to zero, such batteries become unstable and even dangerous to charge. And in order to prevent the battery from exploding, it has a kind of self-destruct mechanism, a built-in circuit that shuts down (read, 'kills') it. The plus is that you are insured against a puddle of acid from the battery, and the minus is that you can be left without a battery at all.

Use fast charging only when needed

Many new phones support fast charging – charging from zero to half in half an hour. Ideal solution for extreme situations – and very harmful to the battery.

Lithium-ion batteries live a long, prosperous life when charged at low speeds. But since fast charging occurs only at the beginning of a cycle, and phones and chargers are smart enough to increase the load only when necessary, there won't be much trouble. But if you're not in a rush, it's best to charge your smartphone the old fashioned way slowly and with a low-voltage charger.

Finally, don't strain yourself!

Taking care of your battery is easy … and being lazy is even easier. And still everything will be all right, if only your head is all right. Usually, lithium-ion batteries last 3-5 years, during which time people change devices most often. And such technical trifles as leaving the phone on charge overnight or putting it on a fast one sacrifice correctness for convenience.

However, avoiding absolutely painful torture for the battery is simple – after all, there is nothing difficult in not leaving the smartphone in the heat or not discharging it to zero. And then it will please you more than once by the fact that it can keep the battery charge for a long time.
