Proper charging of the smartphone battery after purchase. How to charge a new battery on your phone: a few secrets

It seems that it can be more banal than charging your phone? Plug the charger into a power outlet and plug the cord into the charging port and let it charge. And if the gadget is completely at zero, then put it on all night to receive energy from the power grid, and in the morning it will be ready to rush into battle. However, everything is not at all so obvious, and how long you charge your smartphone depends on how long it will last you.

Charging your smartphone correctly is almost a science

Should I charge my phone battery to 100%?

In fact, it is recommended to do this infrequently. To be precise, about once a month it is desirable to "reboot" the battery - that is, completely discharge and then charge up to 100%. This will allow lithium ions, which is one of the main components, to completely go through the entire recharge cycle and maintain the maximum possible capacity. But you shouldn't do this all the time.

When to charge your phone

If the answer “when it was discharged” came to your mind, then you are not quite right. Many smartphone manufacturers say that you need to keep your battery somewhere between 50% and 90% charged as much of the time as possible. The fact is that too low and too high a battery level causes it to exhaust its resource faster. So the gadget will serve you longer than it could.

Should I leave my phone to charge overnight?

For the same reason, you should not leave your smartphone plugged into a power outlet overnight. While most modern smartphones have built-in sensors to disable charging when they reach 100%, they don't fully protect against this. In addition, your smartphone will gradually lose its charge and immediately get it up to 100%. Which consumes a lot of battery life.

The best policy is to charge your phone to 90 percent before bed and turn on airplane mode. Thus, the gadget will almost not lose battery power until the morning, and a sudden call, if someone has the wrong number, will not wake you up. How do you charge your smartphone? tell us about it in our Telegram chat.

Can any charger be used to charge a smartphone

This is highly undesirable. If possible, use the charger that comes with the device, as it will definitely have the correct performance indicators such as power, amperage and other characteristics. Otherwise, try to use chargers from certified manufacturers. Cheap alternatives from Aliexpress can easily damage the battery.

Can fast charging technology damage a smartphone

Most support some form of fast charging. The standard in this case is an 18 watt power supply (while conventional chargers operate at a power of 5 watts). But Samsung even sells a 45 watt charger! While fast charging by itself won't harm your phone's battery, which is built specifically to run at such capacities, the heat generated during the charging process will potentially affect battery life. So we would recommend using fast charging only in emergency situations, and in ordinary life use standard means.

New battery for the phone: how to charge it correctly?

After purchasing a phone in a mobile electronics store or receiving an order from an online store, we immediately begin to study a new device. I would like to explore all its possibilities at once, personalize it with the help of melodies, wallpapers, and other "chips". After the first impulse weakens, the owner of the gadget thinks about how to properly operate his device. The most important part of using your phone is charging it. How well you charge your phone will determine how long it will last. In addition, it is important to know how to properly charge a new phone battery. This will be discussed in this article.

To properly operate your phone, you need to have an idea of ​​what kind of batteries it uses. Most modern phones use . Over the past decade, they have become the dominant battery type in smartphones, tablets, and laptops. Among them there are varieties such as batteries. They differ in the composition of the electrolyte. Otherwise, they are very similar.

The advantages of lithium batteries include high energy intensity, low self-discharge, no memory effect and good discharge current. True, in devices with a discharge current of 10-20C (C - capacity), such batteries cannot work. There, their place is still occupied. An example of such a scope can be called a mobile power tool, warehouse equipment, etc. The disadvantages of lithium batteries include a short service life and a rather high cost.

The service life is about 500 charge-discharge cycles. The time frame is from 1 to 4 years, depending on the intensity of exploitation. Lithium batteries irreversibly lose their capacity not only during operation, but also during storage. It is worth adding that at low temperatures, lithium batteries lose their ability to deliver current.

I would like to say about such types of batteries as. These batteries were used in mobile electronics (phones, laptops, players) before mass production of commercial lithium batteries was established.

Nickel-cadmium batteries are characterized by a long service life (up to 1 thousand cycles), low price and operation in a wide temperature range. Their advantages include easy recovery of capacity after long-term storage or deep discharge. Naturally, there are also disadvantages. This is harmful cadmium in their composition, high self-discharge and "memory effect". All these disadvantages forced specialists to develop a replacement for them in the field of mobile electronics. Nickel-metal hydride batteries were supposed to be such a replacement. They have a much smaller "memory effect", low self-discharge and can deliver a high discharge current. But they have a rather high cost, the service life is comparable to lithium, and the specific energy consumption is much lower. Therefore, they could not become a full-fledged replacement for cadmium.

How to properly charge a new phone battery

Now directly about how to charge a new smartphone battery. After purchasing the device, wait until it is completely discharged. Now you will say that you have seen recommendations about the need not to fully discharge lithium batteries. That's right, this should be done only 2-3 times on a new phone battery, as well as during periodic calibration, which will be discussed below. That is, first we discharge the new battery before turning it off. Lithium batteries have a controller that monitors the discharge and charge of the battery. At a critically low voltage, a signal is sent to the operating system of the phone and the device turns off. Thus, deep discharge of the battery is prevented.

After the battery of the phone is dead, you need to fully charge it. Before that, we recommend that you familiarize yourself with the manual of the mobile device and find out the exact time for a full charge of the battery. After that, you should charge the phone in the off state for the specified time until it is fully charged. As a rule, a fast charge takes 2-3 hours. At the same time, the battery is charged by 80-90% of its nominal capacity. Such a charge is quite suitable during operation and is even recommended, but not for a new battery.

To fully charge the battery of the smartphone will take from 10 hours to a day. The exact time depends on the parameters of the battery (voltage, capacity) and on the characteristics of the charger. The phone is kept switched off. So, the new battery will be concentrated on the accumulation of charge, and will not give it to power the phone's microcircuits. After charging the smartphone, use it until it is completely discharged and charge it again in the specified way. So, 2-3 times. Further in the process of operation, you can already safely charge the battery not completely or not completely discharge it. But more on that below.

If you still have an ancient gadget with an alkaline battery, then you need to “build up” there. And not only a new battery, but also during further operation. If this is not done, then Ni-Cd or Ni-MH batteries will lose capacity as a result of the "memory effect".

But what if you only have a rechargeable battery and no phone? How to charge it? We recommend reading the material about.

If charged to 100%, will it affect battery life?

To answer these questions, we have collected all the information you need.

Many people have already become addicted to smartphones, so much so that some have even become nomophobes (nomophobia is the fear of being left without a smartphone).

Also, many people are constantly worried that their phone can run out of power at any time. However, few people think that battery life is also important.

Battery life

For the average user, the battery can last about 3-4 years, but this figure can be significantly increased if you follow some tips.

It is immediately worth noting that so far there are no eternal batteries. Most smartphone manufacturers report that their devices are designed for 300-500 charge cycles.

According to Apple, iPhone batteries can reach 80% of their capacity after 1,000 charge cycles.

After that, phone batteries can no longer maintain a charge for a long time.

Here are some tips on how to properly charge your smartphone (iPhone or Android phone), tablet or laptop.

How to properly charge the battery

Many people wonder whether it is worth discharging the battery to zero before starting to charge it.

To answer this question, it is worth learning more about the term "memory effect"

What is the "memory effect"?

Batteries are able to remember how much charge is left (only works when there is still charge in the device and it has not been completely discharged).

If you frequently charge from 20% to 80%, then the battery can "forget" about 40% that were not charged (from 0 to 20% and from 80 to 100%).

However, this applies to old nickel-metal hydride and nickel-cadmium batteries, but does not apply to lithium-ion (Li-ion) and lithium-polymer (Li-pol) batteries (we will talk about the latter below).

Li-ion and Li-pol batteries don't suffer from "memory loss" so they should be charged frequently but not completely, and don't let them drain to zero.

How to properly charge your phone/tablet/laptop

Do not charge your battery from 0 to 100%

The rule of thumb for lithium batteries is to keep them at 50% or more at all times. When the charge drops below 50%, recharge it if possible. The best option is to charge the battery a little several times a day.

But don't charge it to 100%. This, of course, will not be fatal to the battery, but regular charging to the maximum will significantly reduce battery life.

It is worth noting that when discharging-charging by 50%, you can increase the battery life up to 1,500 cycles.

To summarize: it is better to charge the battery from 40% to 80%, do not let the charge fall below 20% and rise to the maximum.

Charging the battery correctly

How often can the battery be charged to 100%?

Despite the fact that completely discharging a phone or laptop is not very good, there is still one exception. Lithium batteries (Li-ion and Li-pol) need to be discharged to 0% at least once every 2 months.

This technique is similar to rebooting a computer, or a summer vacation for people. This action also applies to smartphones and laptops.

Such training will help the device calibrate the electronics that are responsible for the correct display of the charge level.

How to properly charge the battery

Should you charge your phone overnight?

Most modern smartphones are smart enough to stop charging when the battery is full, so there's not much risk of leaving your phone charging overnight.

However, it is worth knowing that after a full charge, the battery of a phone, tablet or laptop will feed the device from time to time so that the charge remains maximum. This action keeps the battery in a state of "stress", thereby gradually reducing its capacity.

If you leave your device to charge overnight for a year, you will notice that your phone or laptop runs out of power faster than it used to.

How to properly charge a new phone or laptop

Now, with modern technology, there is no special instruction on how to charge a new phone or tablet. You just start using it, maintaining the charge between 40 and 80%

Previously, if you purchased a new smartphone or a new battery for your phone, then it needed a “buildup”. This means that the battery had to be discharged to zero (until the phone / tablet / laptop turned off). They even advised the new battery to be discharged and charged up to 100% 3-4 times. Now this is not necessary.

Lithium-polymer battery

It is worth noting that the technology for creating lithium-ion batteries improves approximately 1-2 times a year. Therefore, it becomes increasingly difficult to understand the behavior of new batteries after extended storage.

The lithium-ion battery has many advantages, but still, it has some problems associated with safe operation, as well as high cost.

To solve these problems, lithium-polymer batteries (Li-pol) were created, which appeared relatively recently.

More and more modern smartphones, laptops and tablets use this type of battery. In addition, such batteries can be found in modern radio-controlled toys.

What is the difference between Li-pol and Li-ion batteries

Left Li- ion battery, right Li- pol battery

Lithium-ion batteries use a liquid electrolyte, and therefore there are problems when using them. Lithium-polymer batteries work in much the same way, but have a different structure and dry electrolyte instead of liquid. Dry electrolyte is a solid polymer and looks like a plastic film.

Today it is possible to create lithium-polymer batteries up to 1 mm thick, as well as to make them of any shape. It is also worth noting that the aluminum or steel case, which is used in Li-ion batteries, has been replaced with foil in Li-pol batteries.

How to charge lithium polymer batteries (Li-pol) batteries

It is worth remembering that a lithium-polymer battery must have certain voltage limits during its entire life. Most often it is from 2.7 (minimum charge) to 4.2 (maximum charge).

These batteries have a lower capacity, but a longer service life. Li-pol batteries do not like full discharge and charging up to 100%. The boundary condition for such batteries has a bad effect on their service life.

To maximize the life of lithium-polymer batteries, it is worth keeping the charge in the range of 40% - 60% (in extreme cases, between 30 and 80%.).

New Li-pol batteries when buying, they have a charge level just within these limits.

We charge the smartphone correctly

Is fast charging worth it?

Many Android phones have a fast charging feature (this can be Qualcomm Quick Charge, or, in the case of Samsung phones, Adaptive Fast Charging).

These phones have a special code found on a chip, also known as the Power Management IC (PMIC). This chip communicates with the charger and signals to it that a more powerful voltage is needed for a fast charge.

Fast charging heats up the battery, so you should also remove the case. Experts advise turning off the fast charging function if possible.

How to properly charge your phone battery

High and low temperatures harm the battery

* In order not to harm your phone, tablet and laptop, do not leave the device in a closed car, near a stove or heater, or in direct sunlight.

* The same goes for low temperatures, so don't leave your electronics in a cold room, and in winter, don't carry it in an outside jacket pocket.

* A very useful thing for a laptop in the summer is a special stand that provides good ventilation for the device.

How to properly charge the battery of a smartphone or laptop

Can any charger be used?

If possible, use the same charger that came with your phone. If you decide to purchase a charger from a third party, make sure the manufacturer approves its use.

Cheap alternatives can harm your phone. There have already been cases of ignition of cheap chargers.

* Do not wait until the battery is completely discharged.

* Do not charge to 100%. After 80%, you can safely disconnect from the adapter.

* If the battery is still discharged, immediately put it on charge.

* Ideally, the battery charge should be kept at 50%. This is difficult to do, so you can keep the charge between 30 and 80%.

* Frequent charging from the outlet is harmfulLi-pol batteries. Try sometimes to charge from a laptop (just plug your phone into a USB port). At the same time, it is better not to connect anything else to the laptop, otherwise there will not be enough current for charging.

* Li-pol batteries do not like prolonged exposure to high and low temperatures.

* Once every 2-3 months, you need to completely discharge and charge the Li-pol battery i.e. calibrate.

* When you decide to replace the lithium-polymer battery, carefully look at its characteristics (voltage, connector, type, etc.) - they must completely match the characteristics of the battery being replaced.

* Lithium batteries, no "memory effect", therefore, they do not need to be "overclocked", that is, discharged and fully charged several times.

* Do not leave the battery discharged for too long. It is better to keep the battery charged by about 40-50%.

* Every month batteries lose 5-10% of their capacity when fully discharged.

* If you leave a discharged battery for a long time, eventually it will not be able to hold a charge.

* Spare batteries should also be charged at 40-50% and only then store for future use.

Modern smartphones are extremely active in consuming battery power 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 power consumption. And this is only the main source, but there are many additional ones. Accordingly, you usually have to charge your smartphone once a day or two days. How much exactly should it charge?

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, say, 3 hours when fully discharged to 100%. If this is done from the USB port of the computer, the indicated figure can be multiplied by 1.5-2, and all because USB technology produces only a certain amount of current, which limits the charging speed of the device.

Generally speaking, a full charge of a smartphone from the network lasts, 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 the iPhone of several generations.

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 is an approximate average iPhone charging time from 0 to 100%, but once again we recall that these data are only approximate and may vary.

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

Moreover, full discharge harms modern batteries, significantly reducing their service life. Below you can see a table of the relationship between the depth (Depth of discharge) and the number of discharge cycles (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 that the charge level should not fall below 30%.

2. And do not abuse full charges

Users often charge batteries up to 100% to maximize device autonomy. Or, in the case of laptops, they do not disconnect them from outlets 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 its maximum too often, it can accelerate battery wear.

Battery University contributors comment on this: "Partial charge is better than full charge." According to their observations, the device must be disconnected from the mains until the battery is 80% full. If we recall the recommendation from the previous paragraph, we can formulate a simple rule:

For longer battery life, keep it at 30-80% charge.

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

This advice contradicts the previous two. But now we will explain everything. Notebooks and smartphones on Android and iOS show the remaining energy in the battery as a 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 the battery once every 1-3 months, it will not harm it.

4. Don't let your device overheat

High temperatures adversely 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).

lifehacker.com

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

5. Connect the machine correctly to the mains

It would seem, what could be easier than putting the gadget on charge? But even here there are pitfalls.

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

In addition, if you charge smartphones and other gadgets from a laptop via USB, this can create an unwanted load on its battery. To avoid draining the battery in this way, make sure that the laptop is connected to the mains and is 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 away from 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.
