That the battery must be completely discharged so that it does not lose its maximum capacity. Allegedly, the device “remembers” how much energy you spend before the next connection to the power grid, and in the future it can no longer contain more than this amount. This phenomenon is called the “memory effect” and is typical for old nickel batteries, but not for new ones - lithium-ion.

Moreover, complete discharge harms modern batteries, significantly reducing their service life. Below you can see a table of the relationship between Depth of discharge and the number of Discharge cycles that the device can withstand.

batteryuniversity.com

It turns out that the more the battery is discharged, the fewer cycles it can last. Battery University, an organization that researches energy storage, recommends not allowing the charge level to drop below 30%.

2. And do not abuse full charges

Users often charge batteries to 100% to maximize device autonomy. Or, in the case of laptops, they do not unplug them from the sockets for a long time. There is nothing wrong with such exploitation as long as it does not become a habit. If the charge level reaches the maximum too often, it can accelerate battery wear.

Battery University members give the following comment on this matter: “Partial charging is better than full charging.” According to their observations, the device must be disconnected from the power supply until the battery is 80% full. If we recall the recommendation from the previous paragraph, we can formulate a simple rule:

To make your battery last longer, keep it charged at 30-80%.

3. But once every 1-3 months, completely discharge and then charge the battery to 100%

This advice contradicts the previous two. But now we will explain everything. Laptops and smartphones on Android and iOS show the remaining battery power in percentage or minutes and hours. After a large number of incomplete cycles, this counter may lose accuracy. But after calibration, the numbers on the screen again begin to correspond to the real state of affairs. If you calibrate your battery once every 1-3 months, it will not harm it.

4. Avoid overheating the device

High temperatures negatively affect battery life. In the table below you can see the relationship between an increase in temperature (Battery temperature) and a decrease in battery capacity (Permanent capacity loss).

That is why it is very important to ensure that they do not overheat.

5. Connect the device to the power supply correctly

It would seem that what could be simpler than putting the gadget on charge? But there are pitfalls here too.

For example, a damaged or counterfeit charger can damage the battery and the gadget as a whole. Not to mention the danger it poses to surrounding people. Therefore, always use only working and certified chargers from brands you trust.

Additionally, if you charge smartphones and other gadgets from your laptop via USB, this may put an unwanted strain on its battery. To avoid draining the battery in this way, make sure the laptop is plugged in and not in sleep mode.

6. Charge your gadget halfway if you plan not to use it for a long time

Let's say you're leaving home for a month or two and don't want to take all your gadgets with you. Then you need to properly prepare them for inactivity. Apple and other manufacturers recommend turning off devices in such cases, leaving about 50% charge in the battery.

Modern smartphones consume battery energy extremely actively when compared with conventional push-button phones. Why? The main source of power consumption is the screen - the larger it is, the higher its resolution, the higher the energy consumption. And this is only the main source, there are many additional ones. Accordingly, you usually have to charge your smartphone once a day or two days. How long exactly should it be charged?

You must understand that there is no exact answer to this question, since everything depends, firstly, on the model of the device that you are going to charge, and secondly, on the situation in which you have to charge the gadget. What does it mean? This means that depending on the charging method, the gadget can charge for different times. So, if you use a branded charger and charge your smartphone from the mains, it can charge in, say, 3 hours when fully discharged to 100%. If you do this from a computer’s USB port, this figure can be multiplied by 1.5-2, and all because USB technology only produces a certain amount of current, which limits the charging speed of the device.

Generally speaking, fully charging a smartphone from the mains takes, on average, 1.5-3 hours. Accordingly, if a smartphone has a 1500 mAh battery, it will probably charge much faster than a smartphone with a 3000 mAh battery.

Want a more specific example? Let's take several generations of iPhones.

Here's what we got:

• iPhone 5SE, 6, 6S: 2 hours 10 minutes

• iPhone 6 Plus, 6S Plus: 3 hours 40 minutes

• iPhone 7: 2 hours 20 minutes

• iPhone 7 Plus: 3 hours 40 minutes

The above shows the approximate average time for charging an iPhone from 0 to 100%, but we would like to remind you once again that these data are only approximate and may vary.

Most people still believe that a new smartphone, in particular its battery, should be immediately discharged to zero after purchase. And only then can the new battery be used to its maximum potential. Unfortunately, this is not the case at all.

The fact is that a modern cell phone differs from its prehistoric predecessors not only in its touch screen, the presence of the Internet and a built-in camera, but also in its battery.

Previously, mobile phones were equipped with iron-nickel batteries, which actually had to be discharged immediately after purchase. This is due to the fact that these types of batteries had the so-called “memory effect”. The essence of the effect is very simple: when the battery was charged from 20%, the device accepted 80% as a full charge. Thus, due to the first unsuccessful charge, you have already lost 1/5 of your potential energy reserve. Therefore, it is not surprising that buyers of new smartphones are worried about such an issue as the first charge.

But there is no need to panic. Nowadays, in modern smartphones, iron-nickel batteries have been replaced by lithium-ion batteries (i-ion). Therefore, in modern realities, it is correct to ask not how much to charge this or that device, but how to do it correctly.

Modern smartphones, for example, Honor or iPhone, require more regular recharging rather than charging the device in 1 times from 0 to 100%.

Under no circumstances should you allow your smartphone to discharge to 0% - such actions lead to the device gradually beginning to lose a potential amount of energy that cannot be restored in the future.

This is why smartphones remind you of low battery charge already at 20% and repeat when 10% remains. Remember that if your battery reserve has reached such a low value, then it must be charged. The optimal battery charge is between 40 and 80%. Stick to it, and then your smartphone will live as long as possible.

Also, experts from the Battery University portal note that it is advisable to charge the smartphone with 50% of the remaining energy. If you follow this nuance, then, according to research, the life of the battery will increase by 4 times. If the smartphone has restored its power reserve to 100%, then you should not leave it on charge, since the device’s battery overheats, which also leads to a reduction in potential.

However, if you have a lifestyle where your smartphone can only be charged at night, then energy-saving sockets are sold on the modern market especially for you. This device has a built-in timer. Therefore, if you know that your gadget will reach its maximum charge in an hour and a half, set the time on the timer and relax.

Also, high-quality original smartphones already have built-in charge controllers, which, when reaching 100%, independently turn off the flow of additional energy.

However, you need to periodically discharge the device before turning it off, but not more than once a month. This is due to the fact that due to regular recharging, the sensors that monitor the remaining energy may become confused. It is because of this that your device may unexpectedly turn off at 10%. Therefore, once a month, do not be afraid to discharge the equipment before turning it off, and then charge it to 100%, because in this way you will restore the correct operation of the sensors.

By the way, you can learn about the capabilities of your battery easily and for free thanks to the Battery Life application. It will show the number of charge cycles of your device, battery wear, and also indicate which specific applications require the most energy.

How to properly charge a Xiaomi phone

If you are thinking of purchasing a new and fashionable Xiaomi or have already acquired the ultimate Redmi 4x, then there is no point in worrying: charging such a device is much easier than discharging it, because the battery capacity of the latter is 4100 mAh.

However, if your “Xiomi” still loses ground and turns off at 20% charge, there is no need to panic - our instructions are universal and suitable for all types of modern smartphones. You just need to calibrate the charge sensors by discharging the phone to 0% and charging it to 100%.

If this does not help you, then the problem is probably due to the technical aspects of the device. In this case, do not be lazy to refer to the instructions, paying attention to what it says about the recharging duration. Leave the phone connected to the outlet for the specified amount of time. After this, if the phone is 100% charged, you can unplug it. Next, adhere to the above rules. If the phone still continues to act up, then you should contact technical support for advice.

How to properly charge your Android phone

Basically, modern smartphones produce monolithic devices without the ability to change the battery. Dead battery - consider a new smartphone. That is why many owners of modern devices have become so careful about the health of the battery.

However, Android owners have repeatedly noticed that their phone begins to discharge faster in hot weather. The fact is that a lithium-ion battery drains much faster if you allow the device to overheat. Therefore, make sure that your smartphone is not charged while lying in the sun or near a radiator that is on.

Also, owners of Android smartphones are accustomed to using low-quality chargers, as well as cheap Chinese power banks. Despite the similarity in appearance, the contents of such devices are seriously inferior to their original counterparts. Therefore, no one can guarantee how many years such charging will last, and how its operation will affect your phone.

It is also worth considering that a traditional charger is divided into two types of charge:

1. Transformer: a traditional charger that charges the device with a constant, equal amount of energy.
2. Pulse: A charger with a built-in timer that stops the constant flow of energy after 4 hours of use. After this period of time, charging supplies the equipment with small impulses, maintaining the device’s charge without dangerous overheating.

How to properly charge a Samsung phone

As for the Korean media giant Samsung, for example, charging the Galaxy correctly is a piece of cake. In addition to the fact that the entire line of smartphones has Android software, which is constantly updated, the contents of the models are getting better and better every year.

For example, the Samsung Galaxy S9 has a battery capacity of 3000 mAh, while its big brother S9+ has a capacity of 3500 mAh. It is not so easy to waste such a charge, but it is possible.

Remember, if your device is discharged, under no circumstances leave it in this state for a long time. One of the most common reasons why customers contact technical service is the reluctance of the smartphone to turn on after a long discharge.

Otherwise, if you follow the above rules, there is no reason to worry. Samsung is reliable technology.

How to properly charge your phone battery with a frog

If you still haven’t acquired a smartphone with a built-in battery, and your phone cannot be charged using a standard charger, then you can always resort to using a “frog”.

The frog is a charger that can replenish the energy of completely different batteries. Externally, this unit has nothing in common with an ordinary amphibious creature - on one side of the device there is a plug for the socket, and on the other side there is a clamp that ensures contact with the battery.

An important advantage of this device is its versatility, which can charge both a phone battery and a camera battery. The operating principle is very simple: you just need to remove the battery from the device and connect it to the frog terminals. Once you plug the device with the battery into the outlet, the indicator lights will tell you whether it is charging. The light will also change to green when the battery is 100% charged.

It is also worth noting that modern models of this device have acquired adapters and a USB port for phones with a built-in battery.

So, let's summarize:

• do not allow your smartphone to discharge to 0% (except for monthly preventive discharge);
• if it is discharged, put it on charge as quickly as possible;
• try to recharge your smartphone during the day;
• completely discharge and charge the device once a month;
• do not leave your smartphone on charge all night unless you use an energy-saving outlet;
• Do not allow the device to overheat.

What secrets help you extend the life of your smartphone battery? Share in the comments!

Batteries in mobile devices are vulnerable: incorrect charging or charging for too long can damage lithium-ion batteries and their capacity will decrease. The experts at Cadex (a manufacturer of battery analyzers) have a couple of tips to help you extend the life and optimize the efficiency of your mobile device's battery:

• Do not leave the appliance plugged in overnight. In most cases, the charger does not automatically turn off once the battery is fully charged, and a continuous flow of power will overload the battery and can damage it.
• Charge the battery not 100%, but only partially, for example 85%. This will increase its service life.
• Do not wait until the battery is discharged to 10% or lower. If possible, recharge it in at least small portions.

Experts at Cadex estimate that conventional lithium-ion batteries, if discharged to 10% and then fully charged, can withstand 300 to 500 such cycles before losing their effectiveness. At the same time, if you connect your mobile device to the mains without waiting for the charge level to drop below 50%, battery life can increase fourfold.

What's behind these charging tricks?

In principle, of course, it is correct that batteries should neither be fully charged nor discharged. However, in most (modern) devices, manufacturers have already taken care of this problem. For many smartphones, charging stops once the battery is (almost) 100% charged, even if the device remains plugged in.

The process only resumes when battery reserves drop below a certain level (for example, 95%). We made this statement based on our experience of measuring the charging time of various devices in the Chip laboratory.

The same applies to discharge. In this regard, manufacturers also make sure that the device avoids turning off when the battery is completely depleted. That is why 0% displayed on the display, as well as 100%, must be treated leniently, since these numbers do not always correctly reflect the actual state of the battery. These measures taken by manufacturers, by the way, are also pointed out by specialists from Cadex.

Beware of deep battery discharge

With normal use of the device, you are unlikely to do much damage to it. Cadex's recommendations, in our opinion, entail some inconvenience and are more suitable for those users who are too sensitive to their battery.

This is the case if you do not use your phone for a long time, leaving it with an empty battery. Only then does the so-called “deep discharge” occur, which can actually damage the battery.

The mobile phone is a miracle of modern civilization. It performs a lot of tasks and functions. It is difficult to live without a phone in the modern world. In today's dynamic world, it is important that the phone is always at hand and accessible for communication. In this article I will talk about how to properly charge your phone to extend its life and be always in touch.

The batteries in modern gadgets - from the iPhone to Bluetooth headphones - are lithium-ion (aka li-ion) batteries. This is a new type of battery. They have significant advantages over NiMH and other rechargeable batteries that have been used in the past.

The working process of lithium-ion batteries is as follows:

When the battery is charged, positively charged lithium ions move from one electrode, called the cathode, to another, known as the anode, through an electrolyte solution in battery element. This causes electrons to concentrate on the anode, on the negative side. When battery discharges, the opposite happens. As for these electrons, they move along circuits that are external to battery , providing juice.

Compactness of modern batteries

These electrons actually provide energy for your smartphone or tablet.

Li-ions are compact in size. Therefore, it is not surprising that every year smartphones become thinner and more elegant. Improvements in phone design keep pace with the development of batteries. They also become smaller and lose weight.

A lithium-ion battery is usually charged in two stages. First, a process called direct current occurs. This is the part that is really quite simple. A charger for your phone or tablet will apply a constant current of electricity to the battery to return all those electrons to the anode.

The higher the constant current, the faster the battery can charge. High-voltage fast chargers use this first stage to charge quickly (by adding extra voltage to the battery).

Two stages of phone charging

When the battery is 70 percent charged, the procedure changes. In the second stage, the charger ensures that the voltage, that is, the difference in current between the battery and the charger, remains the same. In practical terms, this means that as the battery gets closer to being fully charged, the current the charger sends to it decreases. When the battery becomes full, its charging speed slows down. Once you reach 100 percent, the charge has a hard time leaking into the battery.

All modern lithium-ion chargeable devices have some sort of intelligent power management. It is designed to prevent the battery from overcharging. They'll keep your phone's battery topped up and ready to go overnight with minimal charge.

Most lithium-ion batteries have a rated life of 500 to 1,500 charge cycles.

One cycle is just one charge. But how much energy you expend at one time is a measure called depth of discharge (DoD). She plays a big role. Lithium ions really don't like deep discharge depth. A li-ion that goes through 100% DoD (the user runs it to zero before 100%) can degrade to 70 percent of its original capacity in 300-500 cycles. With a DoD of 25 percent when the user plugs it in, once it gets to 75 percent, that same battery can be charged up to 2,500 times.

What is much more dangerous to the health of the battery is heat. Lithium-ion batteries despise heat. A lithium-ion battery that is exposed to temperatures of about 100 degrees Fahrenheit for a year will lose about 40 percent of its total charge capacity. At 75 degrees it will only lose about 20 percent.

It's better to recharge your smartphone more often

What is not a problem is the number of recharges. Contrary to what you might think, leaving your phone or laptop on all the time is not bad for its battery. This is because your gadgets are actually quite smart.

Meanwhile, a danger you may not be aware of is complete discharge. When your battery stops turning on your phone, it doesn't mean it's actually empty. It is simply not enough for the device to fully operate. When fully charged from 0%, the battery life is significantly consumed.

How can I take care of my precious lithium ion battery

Here are some practical tips for properly charging your battery. They can significantly increase the life of the phone.

Charge your phone more often

This charger is smarter than you think. Leaving your phone on the charger all night (or all day) is much better for your battery than running it at 0%.

Yes, you can leave your laptop on all the time

Don't worry about overcharging the batteries in your gadgets, and especially don't worry about overcharging your laptop. What we just said about phones also applies to laptops. Many laptops are smart enough to cut off the power completely when fully charged.

But maybe you can take out your laptop battery while it's charged if you can

The biggest danger to your phone is not overcharging, but high temperature.

If you use your laptop as a desktop and generate a lot of heat, it's definitely worth getting a removable battery to keep it from overheating and deteriorating.

Do not block ventilation openings.

Keep your phone in a cool place

Speaking of temperature, make sure you don't leave your phone in the sun all day. Also, beware of fast chargers. Although your phone and charger in general are smart enough to minimize damage from high voltage chargers. Many ultra-fast powers can generate additional heat.

Store batteries with a small amount of charge

Charge your phone halfway. Over time they will gradually lose charge. When it drops into the danger zone to 25%, it is better to connect the gadget to the charger again.

Don't let your battery rule your life

If you follow the most basic rules, if you can minimize exposure to heat, your phone will be fine.

Don't be obsessed with taking care of your battery. Just remember two things:

1. Modern lithium-ion batteries are much smarter than the nickel batteries used in the past. Do not trust the opinions of people who advise you to use your charger differently. Follow these rules. They are not suitable for nickel batteries.
2. Your batteries will die. It's unavoidable. No amount of following the rules will save you from having to replace your battery or phone. You can only extend the service life by 1 - 2 years.
