Download battery care for android. Battery Care v6.10 Mod (Power Saver). Basic rules for using batteries

Batteries on this moment the weakest link of all mobile technologies, they develop much more slowly compared to others. In smartphones, the battery lasts at best for two days, this is even with average use. Moreover, if they are not properly looked after, they can seriously lose in capacity. Unfortunately, there is a lot of misinformation about batteries.

Some of the most persistent myths come from older battery technologies and are actively applied to new technologies. Have you heard from the seller in the store the advice to “train” the battery with two or three charge-discharge cycles? Let's see if this is necessary.

Full charge

At the old nickel cadmium batteries there was a "memory effect", they had to be completely discharged from 100% to 0% in order to maintain capacity. Modern devices use lithium-ion batteries, which work on a different principle and do not have a memory effect. In fact, a complete discharge of a lithium-ion battery is detrimental to him. Therefore, the devices provide protection against this, your smartphone will signal much earlier than a full discharge in order to preserve the “health” of your battery. Therefore, without fanaticism, if you infect and you need to leave or talk, safely disconnect from the charger, do not be afraid that this will harm you, it is not necessary to maintain a full charge-discharge cycle.

There is only one problem that small charges and discharges can lead to. Your laptop will be a bit embarrassed by a little drain and may show incorrect battery life estimates. For a laptop, manufacturers recommend performing a full discharge about once a month to help calibrate the time estimate (if that matters to you at all).

Temperature effects

High temperatures can reduce battery capacity. This affects all types of devices, especially for laptops that get seriously hot when performing complex tasks, and the battery heats up accordingly. This heating helps to reduce battery life.

If you have a laptop that is always plugged in, removing the battery can extend battery life by reducing exposure to heat. You won't see much of a benefit under normal use, but if you're using a laptop for demanding gaming, the benefits are substantial.

Conditions environment are also a problem. For example, if you leave your device in a car on a sunny day, the battery will wear out faster. Low temperatures have a similar effect. As they say, wherever you throw a wedge everywhere, in Russia the winter is cold and the summer is hot - we are exposed to all harmful temperature factors.

Don't leave the battery at 0%

Do not leave the battery in a completely discharged state. If this happens, do not panic and run headlong to the outlet, but when your smartphone is dead, do not throw it in a box and do not keep it there for a week. If you let a discharged battery sit for too long, its capacity will tend to zero.

Store batteries at 50% charge

On the other hand, storing a fully charged battery for an extended period of time can also result in loss of power and shorten battery life. Ideally, you should store the battery at 50% charge if you are not going to use it for a while. Manufacturers recommend leaving the battery at 50% if not expected to be used for up to six months.
Storing the battery fully discharged may cause the battery to die, while storing the battery at fully charged, will lose some capacity and shorten the life of your battery.

The laptop is constantly online conveniently, but ...

On the one hand, there is nothing to worry about, but the battery is always fully charged, and it also heats up under intense load. If your laptop is generating a lot of heat, removing the battery is a good idea. If your laptop doesn't get hot, keeping it plugged in all day shouldn't be a problem.

Conclusion

Like all other types of batteries, lithium-ion batteries wear out over time, holding less and less charge. The capacity of the most best batteries will reach up to 80% of their original capacity after / up to 1000 full discharge cycles, average from 300 to 500 cycles.

By adhering to the above, batteries will wear out more slowly over time. Let's hope that you change the device before the battery fails.

It doesn't matter how many gigabytes random access memory and megapixels is inside your smartphone. Moreover, they do not play a role clock frequency processor, number of cores, display resolution and other similar characteristics. That's right, if the device's battery starts to lose all its vital juices in a couple of hours, even the presence of water protection and a fingerprint scanner will not save its owner. However, it is still possible to prevent the development of such a scenario. To do this, you should follow a few rules, which we will now get acquainted with.

Fuck perfectionism

I don’t know about you, but personally I am a hardened perfectionist. For example, it's hard for me to look at the accidental violation of symmetry where it should be, mistakes in words and many other things like that. In addition, it is difficult for me to disconnect my devices from charger until the coveted 100 percent appears at the top of their displays. It turns out that this is not recommended.

According to our colleagues from phonearena, lithium-ion batteries prefer several short charges over one full charge. This will affect the number of charge cycles. In other words, the battery will last longer.

Avoid discharge

As we have already learned, the maximum charge of the battery negatively affects its life. However, there is something worse. We are talking about a complete discharge, upon the occurrence of which the phone turns off automatically. Bringing your device to such a state is categorically not recommended.

Ideal indicator

Not less than important information: Your smartphone's battery is at its most comfortable between 40 and 50 percent charge. Despite the constant flow of electricity, in this case, the battery cells do not wear out.

Avoid high temperatures

Perhaps, everyone has heard about the harmful effects of high temperatures on a smartphone. But what about numbers? A battery will lose 80 percent of its capacity if kept at 60 degrees Celsius for a year.

Among the more adequate data is the loss of about 20 percent of the capacity when using the device at 25 degrees Celsius.

Avoid cold temperatures

Cold has exactly the same effect on the battery as heat. Be careful next winter.

Do not be lazy to go to the outlet

If the smartphone is still discharged and turned off, you need to immediately connect it to the charger. Otherwise, after a while, the battery protection circuit will be put into the so-called sleep mode. The consequences can be dire.

Do you monitor the health of your battery? Share your secrets in the comments to this article.

Though various models There are a great many smartphones and tablets, all of them - happy or not so - owners have one thing in common - each of them, when buying his mobile device, assumes that his new "electronic friend and assistant" will be able to do without recharging for a long time. After all, a mobile device is mobile for that, in order to please its owner a little away from some of the benefits of civilization - in this case, from an electrical outlet.

But not everyone is lucky. Sometimes dreams are shattered when faced with harsh reality. After all, if the battery of even the “coolest” and “fancy” smartphone or tablet suddenly begins to completely give up its “life force” in just a couple of hours, then no cores / gigabytes and megapixels will no longer matter, and it will absolutely not give a damn what branded label printed on the body of the device. Even the most expensive and fashionable device will not bring joy with a battery that is too low-capacity, improperly operated or “killed in the trash”.

The most advanced users know that the battery capacity is highly dependent not only on its factory settings, but also on correct operation, which does not allow the battery to grow old ahead of time. In Russian, you need to use the battery of a smart or tablet correctly and wisely, so that he is not lazy and gives out everything he is supposed to, and also does not suddenly die before the time measured at the factory.

That's just with the correct handling of the batteries of electronic devices, we will now understand.

And as usual, I'll start with a warning. There are a lot of subtleties in the operation of batteries, and even if they are briefly described, the article will still come out a little voluminous. Especially for those who “do not know all the letters, or have difficulty putting them into words,” we have prepared a short, lightweight version of the guide “”. It outlines the most basic rules in general terms. That's enough for a start. A quick guide can also be useful to those who always have no time, but want everything at once. Well, this is not the smallest article addressed to those who want to understand the topic and understand the details.

Battery life

The declared capacity of the battery is steadily declining due to its aging. These devices are not only subject to wear, but also have their own service life, which developers and manufacturers have measured for them. On too for a long time The “life” of batteries is not calculated - physico-chemical processes are continuously taking place inside them, which slowly but surely destroy the internal structure.

If we take the natural "lifetime" of the battery, then it is designed for about 2 years. But this figure is very, very approximate - the operating conditions affect it too much. Natural reasons that shorten this period include a strong overcharge or a complete discharge of the battery, as well as factory defects in the power management circuit.

Another influencing factor is the activity of use - the number of charge / discharge cycles and the condition of the battery cells themselves.

Basic rules for using batteries

The first rule: exclude even the slightest possibility short circuit when the battery contacts through any object (or wiring, conductive liquid, etc.) close to each other. If, for example, the tablet is non-separable, and the battery cannot be pulled out of it, then everything is somewhat simpler. If the battery is removed without problems, then you need to look both ways and not throw it anywhere.

• modern battery mobile device cannot be disassembled;
• you can not charge it in the cold;
• do not put the battery or device with it in water or fire;
• do not use the battery at very high (greater than 45°C) or low (less than 0°C) temperatures;
• do not store the battery completely discharged - complete discharge dramatically accelerates its aging.

Battery capacity and discharge rate are greatly affected by high temperatures - it has been proven that when used at 25 degrees Celsius, the actual capacity drops by almost 20%. Severe cold can be even more destructive.

If you notice that your smartphone or tablet has become very hot due to the battery, I strongly recommend that you stop using it and contact the service for a check. Even if the battery is visually swollen, it should be replaced immediately.

A fairly common used and relevant rule: if you still didn’t keep track, and your mobile device was discharged to zero and automatically turned off, you should connect it to charging as soon as possible. Otherwise, after a certain period of time (in different devices various) a special battery protection circuit will switch the battery to the so-called "sleep mode". The consequences of this are highly dependent on the device of a particular device and can be very deplorable. It is not so rare that only specialists succeed in “awakening” it again. service center, and even then sometimes with great difficulty and for a lot of money.

It is also recommended to keep the tablet cool and away from the knees. Without fanaticism, of course - you should not climb into the refrigerator with him - but you should not allow the device to overheat - if you lie in bed with it, do not bury it in a soft feather bed and do not wrap it in a blanket - it will not freeze without you. Any electronic device should be cooled normally, and mobile too. At least due to natural air circulation.

Types of modern batteries

By type, they can be divided into two groups: already obsolete and still modern.

The first group includes rechargeable batteries nickel-based - nickel-cadmium and nickel-metal hydride. At one time (not so distant), these technologies were considered quite advanced. However, nickel batteries had one extremely unpleasant feature that completely crossed out their advantages - their "memory effect" was very pronounced.

I will try to explain "on the fingers" to those who are not familiar with the term "memory effect". Let's say your battery is half discharged, and you, without waiting full discharge connected it to the charger. The point from which a new charge began is immediately taken by the nickel battery as 0, and the volume of the remaining “space free from the charge” is taken as the full volume of the battery. Accordingly, if you connected the battery to charging when there was still 50% of the charge left in it, its full volume will immediately be set to half of the factory one. Return normal capacity such a battery could only succeed in a repeated long and tedious “buildup” process, and even then not always. Naturally, here I exaggerate a little, and in practice everything came out a little less sad. But exactly what "slightly". There was little pleasant in the “memory effect” for the user, and even the nerve cells were burned by the users ...

Now you can forget about the batteries of the nickel group, they are completely outdated. They can still occasionally be found in various inexpensive household devices. However, they are no longer used in mobile devices. Unless, of course, you didn’t take it into your head to make yourself happy with a penny smartphone assembled in some basement “on Uncle Liao’s knee” from ten-year-old waste products. Well then it becomes entirely your problem.

The group of more modern batteries includes lithium-based batteries. "Memory effect" formally they also have. However, in a practical sense, it is such that you can simply forget about it. Forgot? Anyway, we won't go back to it.

The first generation of lithium batteries - lithium-ion - is now a thing of the past. They were replaced by new devices. The most advanced technology today has lithium-polymer batteries, which have a number of advantages over their predecessors:

• due to the increased capacity, they can be made more compact and light, and this is extremely important for mobile devices;
• they have the lowest self-discharge, that is, they discharge more slowly during storage;
• separate battery cell high voltage. This means that it is theoretically possible to create batteries consisting of only one cell, which will greatly simplify and reduce the cost of the device;
• lithium polymer batteries have very low maintenance costs;
• and for a snack: these batteries have a long service life. The longest of all that exist on the market.

The vast majority of batteries in today's tablets and smartphones belong to the lithium-polymer group.

Well, now let's move on to the most "delicious" (almost - the very best, I still leave for the end of the article).

Charging the battery in various situations

You often hear advice to "pump" your battery immediately after purchasing the device. If you are lazy, you can not do this, nothing bad will happen. In the days of nickel batteries, this was a mandatory process, now it is optional. However, there is one point. During the first charge-discharge cycle, the device's power controller is calibrated, and in the future it will work more correctly. Although no one forbids carrying out this procedure not at the first start, but a little later.

Further. In daily use, be aware that lithium batteries prefer several short charges over one full charge. This has the most positive effect on their service life.

More. Quite often it is advised not to leave your smartphone or tablet on charge all night. Like, it kills the battery. This is one of the myths. Indeed, batteries are very sensitive to recharging, but modern electronics have long been able to turn off the device when it is fully charged. And in the future, it will only occasionally reconnect again for a short period of time to replenish what was spent. So there is no danger in long-term overnight charging - as soon as the battery is fully saturated, charging will be interrupted.

Despite the above that modern batteries do not need to be "pumped", I recommend doing this once a month or two. I explain.

Despite all the "advanced" current devices are still not perfect. The sensor showing the degree of charge may go astray. Also, the power controller can go astray. In this case, for example, you may notice (or may not notice) oddities in the behavior of the remaining charge indicator - an inadequate forecast of the remaining operating time.

To bring the electronics back to life, once a month or two, fully discharge the battery, and then charge it to 100% in one go. To fix the sensor and calibrate the power controller again. By the way, the battery life from this can last a bit.

A little about discharge

I already wrote, but I will repeat again. DO NOT let the battery drain to “total exhaustion” when the device automatically turns off. It would be better not to allow the discharge even by half. Therefore, if you decide to “pump” the battery of your device (as advised a little higher), I strongly recommend that at the end of the discharge you independently control and “catch” the state as close as possible to zero, but not yet 0, ideally - 1%. Or at least 3%. The matter is facilitated by the fact that in most devices with default settings the system throws warnings at 15% remaining charge, then at 5% and then at 3%.

And finally, the very best:

How and what to charge the battery in different situations

Remember the basic rule for charging batteries: the weaker the charging current, the longer it will take, but the battery itself will last MUCH LONGER. This rule applies to all batteries of any type without exception. That is, if you are not in a hurry, charge the battery with the weakest charger you have. You can also attach the device to a computer - the charging current supplied via USB is very small and greatly contributes to ensuring that your battery "does not go to another world" ahead of time.

If you need to charge the device urgently, you can use a powerful charger.

Again, without fanaticism, I still would not recommend connecting the smartphone battery to the KamAZ battery charger. Unless, of course, you like expensive, loud and spectacular fireworks.

There is a problem that in modern powerful smartphones and tablets with capacious batteries(usually from 2000 mAh and above) powerful chargers are also included. After all, the manufacturer is not at all interested in you buying one device from him and using it for years. And the sooner your battery “expires”, the sooner you will run to the store for a new one with money in your hands. And even for a new smartphone / tablet, if you pull the battery out of it and replace it is problematic.

Therefore, I advise you to look in stores for a charger with a capacity of about 20% of the capacity of your battery. If you managed to find this - use it for everyday charging. And use the charger from the kit when you need to charge quickly.

By the way, it will sometimes be useful to use non-native chargers from third-party manufacturers. You can ask a friend-parents-children, etc. Extra training for your battery.

The charging process will also depend on the resistance of the hooked cable. In practical terms, though, you won't really notice it.

By the way, it is better not to try to charge a completely dead battery with a weak device - if it is empty, then the full potential of a standard charger will be required to charge it, since in this case enough a large number of energy. At least at the beginning of the procedure, until the empty battery capacity is replenished at least a little.

More. During charging, it is not recommended to make active movements with your device, and even more so to subject it to heavy loads. Not only will this greatly increase the charging time, but it can also significantly reduce the life of the battery and charge controller. And then cause their premature failure.

Although, I think that checking mail and reading articles on websites will not harm the device. As long as you don’t feel like chasing some heavy toy while charging.

Well, if you feel like leaving your smart or tablet on charge all night, then no problem - take the weakest of your chargers. Or attach the device to a computer or laptop plugged into the outlet - most of them (though not all), even in the "sleep" state, can supply charge to a device connected to them via USB.

And as a result, let me remind you again. Do not allow extreme situations, that is, a complete discharge or recharge. Remember that the optimal charge for the "lifetime" of the battery is 40% -60% of the full capacity. These values ​​and try to maintain. Indeed, within these limits, even with a constant influx of electricity, the battery cells practically do not wear out.
