The iPhone 4 battery is charging. The iPhone is discharged - what to do and how to charge it without a power supply

Articles and Life Hacks

Information on charging rules is of interest to many users who want their smartphone battery to last as long as possible. This is especially true for all new owners who do not know how to properly charge your iPhone... Of no less interest is the question of how, because too quiet a sound makes using the device uncomfortable.

The list of topics of interest to them is very diverse. What is the best way to charge your smartphone with frequent use? How many charge cycles do I need after purchase? Let's consider the answers to them in more detail.

IPhone battery and the main rules for charging it

Currently, iOS devices have built-in polymer lithium-ion batteries.

It should be noted that lithium is not only the lightest metal (which makes the device lighter), but in combination with the rest of the battery materials provides a longer battery life. Such batteries can be charged at any time, unlike nickel batteries, with which you must definitely wait until they are completely discharged.

However, after iPhone purchases It is highly recommended to fully discharge and charge the device 2 times in a row. The charging time is at least 4 hours.

As a rule, it is in the first hours of charging such batteries that up to 80% of their capacity is replenished, and then recharging with a weak current continues. The very first stage takes 2 hours, and the next one takes 2 more hours (provided that mobile device will not be used while charging).

It is useful to carry out a full discharge-charge cycle of the battery with frequent use of the iPhone about 1 time per month.

So how do you properly charge your iPhone? There are some basic guidelines on this topic.

So, it is in his power to disable the delivery of notifications from App Store and active delivery Email, download new data less often and use location search services (item "Geolocation" in the main settings). All this will allow the battery to work without recharging for much longer.

Other tips: turn off Wi-Fi (3G, Bluetooth), turn down the brightness, turn off the equalizer and backlight, and use less third-party apps.

You can also save battery power by turning off your social music network from Apple called Ping (available from firmware version 4.3). To do this, go to the main settings, select the "Restrictions" item, enter the password, then find the Ping item and disable it.
In order for the battery of the device to work longer, it is advised not to leave it in the open sun or inside a heated car (even in a case), and also to allow exposure to low temperatures.

Charging iPhone correctly: short instruction

In the box, along with the smartphone, you can find those components that you need to charge the device. In particular, it is a network adapter and USB cable.

If the smartphone was brought from the United States, network adapter maybe a flat plug. In this case, for a small amount, you can purchase a special adapter for a European outlet. At the same time, it is allowed to use charging from a computer via a USB cable, although this is not always convenient.

In addition, the user can also buy a European network adapter - however, it will cost him a little more.

Now a little about the charging itself. It is strongly recommended to use branded accessories, but in no case pirated products. You can charge your iPhone both from your computer and from the network via an adapter.

Although the battery that comes with a new phone has a small amount of energy (quality control result), it needs to be charged for the first time, which should last for about a day, or at least overnight. Thanks to the inventors who came up with a three-stage battery charging technology. Thanks to this, the phone battery works at the highest possible level for it.

Instructions: how to charge a new phone battery correctly

Connect the charger cable to iPhone. Insert Charger into an outlet.
Please be patient as it will take a long time to charge your phone for the first time. If the battery is charging inside the phone, it is best to turn it off unless otherwise instructed in the device's instruction manual. The first charge takes at least 12 hours.
After completing the first charge, completely discharge the battery. Only then put new phone for the next recharge. This will "stretch" the battery - to achieve the maximum possible capacity. To completely drain the battery in a new phone, use it in the usual way... But if you need to speed up this process, you can start video playback, download several large files via Wi-Fi, play "heavy" games, etc. The more times you repeat the "full discharge - full charge" cycle of the battery, the longer the time autonomous work your mobile phone will delight you.

Tips and hints

If your phone does not turn on after 12-24 hours of recharging, or the battery indicator shows a minimum level, do not be alarmed - this sometimes happens with devices that have just rolled off the assembly line. Leave it to charge for another 12 hours, and then try turning it on again. If the problem persists after that, contact the service center. Have a technician investigate the cause of the problem or replace the battery.
Knowing how to charge a new phone battery, you should not disconnect it from the power adapter after a couple of hours, even if the indicator shows the maximum level. Leave the device connected for the 12-24 hours recommended here. The indicator often does not correctly show the charge level of new batteries.
Never charge the battery in a hot car or a sunny window sill. This can cause the battery to overheat, leak its contents, or even explode. In addition, never insert a damaged battery into the phone or try to charge it, as this can lead to undesirable consequences: damage to the handset and even injury to the user.

After one and a half to two years of active use of a smartphone, you should

The battery is the heart of the smartphone. Without its correct operation, you cannot get everything you would like from the device. Of course, if your iPhone's battery runs out quickly, you can buy and not worry about it. But a quick discharge is only the first sign that soon Apple's device will need to be carried in. How to distinguish this and what to do if the smartphone battery does not work? Also, the question often arises of how to replace the iPhone battery. It is important to figure out in time whether this is possible.

Why do smartphone batteries deteriorate over time?

Unfortunately, the battery is practically the only "iron" part of the gadget that is subject to physical aging. Over time, it will begin to lose capacity, which will cause the charge to be consumed much faster. Even lithium-ion and lithium polymer batteries that do not have the "memory effect" that spoiled the nickel-cadmium batteries used in older models.

Loss of capacity appears after a certain amount charge-discharge cycles. In their process, the battery loses its capacity. It will charge faster, but it will also consume energy too quickly. Manufacturers specifically reckon that the battery will last no more than 1000 full charge cycles without losing capacity. After that, it begins to decline quickly enough.

How to charge your iPhone to avoid ruining your battery

To properly charge your device, you need to remember some rules. Such an elementary action also requires a competent approach. Otherwise, there is a chance that the battery will soon say goodbye to a good third of its capacity, and you - with several hours of device operation.

General charging rules

It is necessary to remember some of the nuances and features when using, which every smartphone owner should definitely know. Compliance with them will keep the battery in good order.

Can't discharge iPhone to 0%. A full charge-discharge cycle will shorten the life of the device. It is much more profitable to charge it after it reaches the 30% mark. In this case, the battery will suffer less. For example, when discharged to 100%, the battery will “live” only 500 discharge cycles. If you constantly put it on charge, as soon as the energy mark reaches 50%, the number of cycles will increase to 1500.
Do not use the device while charging. Not only will energy accumulate more slowly - there is a risk that the battery will be damaged this way. In addition, then the gadget will overheat, which is not good for the battery, as well as for other electronic components.
It is necessary to use only high-quality USB-cables and special ones for them. A poor-quality wire can not only fail to fit - its characteristics will not match the gadget: it can ruin the charge controller. And replacing the latter is a big problem.
Do not store the battery in a discharged or fully charged state. Not using an iPhone? Charge it to 50% and leave it lying. In this case, its battery will last much better.
It is recommended to completely discharge the battery once a month until the smartphone turns off by itself. This will allow you to calibrate its capacity due to the presence of minimal "memory effect".

At the same time, it is worth dispelling several myths that swarm around the old memory around modern batteries for phones and tablets. They are not just useless today. These myths harm the device and its owners to some extent.

do not leave the smartphone on charge for a long time. Wrong - modern iPhones are equipped with a charge controller. If the battery is full, not a drop of energy will enter it, the controller will not allow this. Consequently, the "recharge" effect will not occur;
you cannot recharge the smartphone until it is discharged to 0%. This is very harmful advice, since in this case the battery will live less. It has been dragging on since the times nickel cadmium batteries, which "memorized" the last value of the battery before charging, and then allowed to take energy strictly before it.

These two myths are a relic of the past, when phones did not have even a fraction of what they can now. Previously, it was easy to ruin the battery by leaving the device on charge overnight, and lose some of the capacity simply by charging the battery with 10-20% energy. Now this is no longer relevant - technologies have stepped forward, so they will allow you not to worry about such trifles.

How to charge a new iPhone battery

Each new battery requires a special treatment at first. It must be calibrated in a certain way so that there are no problems with the duration of its further work. It is especially important to immediately start calibrating a new battery from the first days of "life" inside a smartphone. Because then correcting the situation and restoring the lost capacity due to improper charging will be quite difficult.

Of course, the battery that went on sale together with the purchased smartphone, or any other, "out of the box" has a certain amount of energy. It is advisable to carry out the first charge immediately after the purchase, by setting the smartphone to charge for 12 hours. At the same time, you should not turn it on and even more so use the iPhone - the charging process should take place in complete rest for the device.

After 12 hours, it is necessary to discharge the battery before turning off the gadget on its own. This procedure allows you to calibrate the battery by squeezing the full capacity out of it. Without it, some of the battery reserves remained in a "sleeping" state. Therefore, the period that the device could stretch without recharging would be somewhat reduced.

This full charge and discharge cycle can be repeated several times. But you should not get carried away - one or two calibrations will be enough. Otherwise, the battery will last longer, but it will also run out of charge / discharge cycles faster. That is, he will develop his resource and stop holding energy as he was originally supposed to.

Immediately after carrying out such a calibration procedure, you can fully use the gadget. That being said, it is important to remember how to properly charge your iPhone and what not to do with it. This will allow

Which cable to use to charge iPhone

It is necessary to correctly select all components and consumables for your Apple device. And if either special glass may not be branded, then it must necessarily be, if not Apple's, then at least certified. Unfortunately, there are a number of reasons for this.

The first is a tricky system charging iPhone... Regular lightning cords will not work for her. In order for the energy to start flowing into the battery, a special chip is needed in the plug. Otherwise, a smartphone running iOS 7 or more new version, will literally swear at an uncertified cable. This ID chip doesn’t fit into cheap Chinese wires that could harm the iPhone. Therefore, you will have to buy more or less high-quality and expensive cords. Such models will comply with the MFi (Made From iPhone / iPad / iPod) license. Apple certifies certain firms by receiving a small percentage on cable sales. Consequently, the products of such a company can be safely bought.

The second reason is the risk of accidentally burning the iPhone charge controller with a poor-quality cable. Even if the product is certified, in the lower price category there is a chance to accidentally stumble upon a wire that is not equipped with the chip needed to control the current. Of course, the device itself will cope with the voltage for some time - but constant drops and increased load will first disable the chip controller, and then burn the battery. And a low-quality cord will quickly fray and break. Braided cables, for example, can live a very long time.

Which cables can you buy for the iPhone

There are several specific companies that are closely engaged in the manufacture of special products for the iPhone, including Lightning cables... It is worth paying attention to the models produced by these brands. Because they all meet Apple standards and have worked flawlessly for years.

The first company - with its unusual solutions and beautiful appearance products for the iPhone. USB cables from this company are striking in their variety. The manufacturer is not limited to standard solutions and colors. You can find literally everything on sale - braided cords, flat ordinary cables and wires of incredible colors. The quality, in turn, is as high as the originality of Remax. The product is able to work for several years without interruption. This is why Remax is loved by many iPhone owners.

Then you can mention. The firm is not as diverse as the previous representative of the Apple accessories market. But on the other hand, you can find quite interesting and convenient solutions for any purpose. For example, a spring cable, which is ideal for. It does not break or break - it is too difficult to damage such a wire.

By purchasing cables from these manufacturers, the buyer will never receive a fake that can damage the iPhone while charging. Because these brands are responsible for quality with their own reputation and Apple's MFi license. Naturally, they do not want to lose it.

What you need to do to avoid charging your smartphone so often

If you're worried about your iPhone running out of battery quickly, it's probably not a poor charger or aging battery. Chances are, the problem lies within the software component.

It is important to understand that all applications and functions used, even if they work in background will draw energy from the battery. Therefore, it is necessary to constantly turn them off so that they do not consume the battery. What parameters and applications to pay attention to:

Wi-Fi, Bluetooth, 3G Internet - users often forget to turn off these services after use, and they continue to broadcast the signal that no one needs into space.
Geolocation - it should be turned on only when you need to directly navigate the terrain or put a mark on virtual map cities. In other cases, it is not needed.
Increased screen brightness. Display is the main reason fast discharge battery. Most often, the brightness of the screen is increased on a sunny street in order to at least see something. But this problem can be solved or similar on the display.
"Heavy" applications - Skype, MS Office for smartphones and the like. If any unnecessary applications work in the background - they need to be turned off. And then the energy will not be spent on them.

In addition, it is important not to forget to exit any applications when they are finished, even if you still need them. For example, you might want to minimize the browser to the background if you don't need it right now.

Unfortunately, a number of other reasons can also negatively affect the battery. Do not overheat the smartphone battery above 35-40 degrees Celsius. Excessive heating will degrade the capacity. Hypothermia below -15 degrees Celsius has a similarly unpleasant effect on the battery. Therefore, you should not carry your iPhone in your bag or outside pocket in winter. But you can buy either fabrics made in the form or - it will warm the gadget, which will allow you to use it outside in winter. And in the summer, you cannot charge it on the windowsill or on the dashboard of the car.

How to know when it's time to change the battery

The battery can be diagnosed on your own, it is not necessary to contact service center for making a "diagnosis". Most devices are easy enough to get a good look at and work with them for a couple of hours.

The most striking sign is the disconnection of the device, when a little charge supposedly remains inside the battery. Typically, the iPhone turns off when the charge is 10-20%. This is a prime example of a battery malfunction. In addition, if it loses its charge in just a matter of hours, this is already a sign of damage or aging: no program can drain the battery so quickly. But if the smartphone heats up, there is a risk that it is faulty. If the battery or processor is warm, this is an indicator that your iPhone is actively working. That is, there is energy, but it is spent on something else. Perhaps a virus has sneaked onto the device. It is worth checking what the reason is with the help of the service center.

The main symptom of battery degradation from time to time or mishandling is that the charge is lost too quickly and the time required to replenish it is reduced. If before the time of the smartphone was enough for the whole day, but now it suddenly began to "starve" after a few hours - this is a reason to think. However, do not forget that this may be influenced by a large number of applications or high screen brightness.

The next diagnostic option is to examine the battery itself for deformation. Unfortunately, for iPhone this advice is not an easy one, because you will have to disassemble the device case for inspection. Although at a sufficiently serious level of wear, it will be possible to determine the deformation "by eye".

To do this, you need to examine the back cover if it is made of plastic. It will rise a little, acquire a kind of hump. This is a sign that the battery underneath is swollen. The reason is that over time, the battery begins to emit gas during degradation. And as soon as this process has begun, you need to replace the battery. Accidental shock or overheating can contribute to a microexplosion.

If the smartphone is made of metal or glass (like latest versions iPhone), the battery will not deform the back cover. But on the other hand, it will affect the operation of the touchscreen - the display will be slightly convex and may creak when pressed. In addition, if the display is swollen, it will gradually begin to peel off. However, this can happen not because of the battery, but after falling without. In any case, it is worth visiting a service center to find out the cause of creaking and stains.

Can I replace the battery on an iPhone by myself?

Apple adheres to a strict principle - never make smartphones with an opening back cover. And they still do it - the iPhone is very difficult to open to replace the battery. This can only be done by an experienced person who previously faced a similar need.

Of course, replacing the battery on an iPhone of any generation is possible. But this will take a little time and enough courage. Unfortunately, there is a great chance of accidentally damaging your smartphone in the process. Therefore, it is worth entrusting the opening of the gadget and the replacement of the battery to professionals from the service center. They will be able to make your device live a long and happy life.

How to replace iPhone battery

Different models of smartphones from Apple have a different principle of opening and removing the battery. Somewhere it will be more difficult, somewhere it will be easier. Naturally, such an intervention carries a certain risk.

But it's worth remembering - first you always need to stock up on certain tools. Otherwise, it will not work to open the smartphone. You need to find:

A flat plastic object for opening the latches.
A special five-blade screwdriver called Pentalobe.
Suction cup is powerful enough.
A regular Phillips screwdriver.
Long, thin object for lifting the battery.
A small, soft piece of cloth.

This toolkit is enough to open any device without any problems, albeit with a certain risk of ruining the smartphone. Naturally, you need to buy a new battery. Before disassembling the Apple case, be sure to turn off the device.

iPhone 4

First of all, you need to take a five-pointed screwdriver and unscrew the two barely visible screws located near the charging connector.

Then gently slide the back with two fingers. iPhone panel from the charging connector. It will move a few millimeters. After that, you can lift it up - just gently pull on the upper edge, which protrudes beyond the body. The device must be put with the charging connector towards you, with the screen facing down.

It is necessary to disconnect the battery cable. It is located closer to the lower left corner of the battery. To do this, you need to very carefully unscrew the screw and disconnect the silver connector. IMPORTANT! Do not touch the contacts with metal objects! This will provoke short circuit- and then the phone will definitely have to be carried to the service center. It is very important not to bend any fasteners in the process. In addition, there is also a latch under the cable fixing screw. coaxial cable- a small bar that is attached under the train itself. It must be put in place before assembly.

After that, you can start removing the battery from the case. And this is where the problems begin. The bottom line is that the battery, in order to avoid "dangling" inside the case, keeps on good glue. And so you have to literally rip it off from the case. But for this, you can warm up the battery with a hairdryer - it is still damaged and will go for disposal. If the battery is still needed, it is not worth heating it, you will have to tear it off like this.

To remove the battery, you need to pull on the plastic tab (not for the train!), and put some long and durable object into the gap formed. Preferably plastic. Then they, like a crowbar, need to very carefully lift the battery (do not press on the space under it - there is a risk of damaging the device), simultaneously pulling it out by the plastic tab.

After that, you need to install a new battery - and you can put your smartphone back. If you did not have a protective cover or film, then dust and dirt will surely accumulate under the cover. It is recommended to remove it before assembly.

iPhone 5

This generation understands differently than the previous one. This time, you will need to remove the front panel with the display and touch-screen, and not the back cover. Therefore, the risks during disassembly are much greater - there is the possibility of accidentally damaging the screen and camera cable. First of all, you need to unscrew the two screws with a five-pointed slot near the Lightning connector.

Then take a suction cup and attach it to the display just above Home buttons.

It is necessary to raise the display - and in the gap formed, disconnect the ribbon cable of the Home button, for which shove some thin plastic object and very carefully pick it up first the bracket that covers the plug, and then the ribbon itself.

And then with the same object, you need to very carefully squeeze the latches that hold the screen in place. After that, you need to EXTREMELY gently lift the display. It also sticks to the trains in the upper part, it is important not to break them. Place the display at right angles to the chassis. To the right of the battery, in the very corner of the device, there is a bar with several screws. They have different lengths - it is important to remember where which one.

The bracket must be carefully removed and then disconnected with a plastic tool the shield cables located under it.

Then we find the bracket on the screws, located below the plastic tab. It must be removed by unscrewing all the screws, and then remove the battery cable with a plastic tool. When assembling, it is important not to confuse the screws - they have different lengths.

Then you need to pry the battery with a plastic tool to remove it from the slot. You can gently run a few times around the perimeter, detaching the battery from the glue on the case. Models 5S and older use double-sided tape, which will need to be pulled out before removing the battery.

It is important not to damage motherboard... After that, you can safely install the battery, prepared for replacement, and assemble the gadget in the reverse order.

The iPhone 6 is disassembled in a similar way - only the position of the screws and cables can change. You will also need to pull out three stickers under the battery, which are located at the bottom of the device under the battery.

As you can see, it is easier to disassemble a nuclear warhead than an iPhone of any generation, if you do not have some experience and skill. Therefore, we recommend that you contact the service center in order to exclude the possibility of accidental damage during the battery replacement process. To give the gadget to the craftsmen means to provide it with high-quality repairs without consequences.

So, today we will talk about charging the iPhone and how to properly do this process. If you want your iPhone battery to last as long as possible, then this material is for you.

In fact, this topic has been touched upon thousands of times and each time we learn something new. But there are some points that are simply outdated, or just plain lies.

In addition to the main topic, I would like to touch on a couple more points about charging:

Probably since the very first phones appeared, we were very worried about this issue. We tried from time to time to fully discharge and fully charge.

Today it is not relevant at all. Batteries have become completely different and today the whole point is only in the number of charging cycles.

For example, if you bought a phone, then in the next two years you can definitely not worry about how exactly it is worth charging your iPhone. Like the smartphone itself, the battery will wear out over time and must be replaced.

The capacity of the battery will decrease over time and it will not depend on your charging methods at all. So we just don't think about this question.

To make the process of charging the iPhone faster, there is not so much that needs to be done. Here you can divide this question into two parts: with the help of the phone itself, or with the help of additional means.

The first method is quite simple - when you put the phone on charging and you understand that you need to somehow speed up this process, then just turn on the Airplane mode, or turn off the phone completely.

The second method requires replacing your power supply, or just buy a Power Bank. If you buy any of these, just make sure the output current is 2 amps.

You bought a brand new iPhone and now you don't know how to charge it for the first time. The main thing is not to panic in this situation, everything will be fine.

As I wrote a little above, exactly how you charge your phone does not matter at all. Therefore, when you have little charge left or you just need to charge according to the situation, then we just do it and are not afraid.

The further state of your battery depends only on the type of use of the smartphone. If you like to actively play games and drain the battery very quickly, then of course you will have to change not in two years, but for example one and a half years.

Each person has a different way, so we just use it and don't bother.

I want to say yes and yes again. Even by going to the official Apple website, you can find confirmation of this. The power supply from the iPad is simply more powerful, because you need to fill the volume more.

So you can charge, but it's better not to get carried away with it. After all, the number of cycles will certainly decrease, and the days before the battery change is approaching.

I only recommend using this option if you really need to quickly charge your gadget. In other cases, we use the standard version.

Speaking of Chinese cables, this is an evil that can burn your iPhone. It is not necessary to use original cables, there are a bunch of others that charge quite well.

Just look at the packaging or there is support for Apple certification. If it is, then everything with your phone will be ok.

Hello everyone! It would seem that the answer to this question is quite simple and you need to charge the iPhone exactly as long as the charge is full and its indicator stays on near the battery icon. As soon as the battery indicator "turned green" and filled completely - that's it, you can safely disconnect the charger. Is it logical? Of course!

However, there is another side to the issue. For example, some users want to know the exact number of hours and minutes that the iPhone should be on charge. And they have the right to do so - such data is never superfluous. Also, especially often I am asked about how much should be recharged new, just bought iPhone.

In general, I can only explain all this fuss about “charging duration” by the fact that some kind of magic is still hovering around the iPhone. Beginners are afraid of doing something wrong and damaging the device in any way, even when it comes to something as simple as recharging. Looking ahead, I can note that this is almost impossible. But first things first, let's start!

The first thing to pay attention to is that the charging time, even for two identical iPhones, will never be 100% the same. The rate of filling with energy depends on many factors, and here are some of them:

How much the battery is initially filled.
Is the original wire used (power supply).
Where does the power come from (computer or outlet).
Adapter power. For example, Apple is officially charging the iPhone. And of course, in this case, everything will go much faster.
Whether the smartphone is in airplane mode, connected to Wi-Fi or cellular networks, etc.

And this is not all the moments! So if your friend's phone charges in 2 hours, and yours in 2 hours and 30 minutes, then this in no way means that you have a marriage, and you should run to change it.

However, there are some average iPhone charging times and they depend primarily on the battery capacity of a particular model:

Model	Average charging time
iPhone 4, 4S, 5	1 hour 40 minutes
iPhone 5S, 5C	1 hour 50 minutes
iPhone 5SE, 6, 6S	2 hours 10 minutes
iPhone 6 Plus, 6S Plus	3 hours 30 minutes
iPhone 7	2 hours 20 minutes
iPhone 7 Plus	3 hours 40 minutes
iPhone 8	2 hours 10 minutes
iPhone 8 Plus	3 hours 30 minutes
iPhone X	3 hours 30 minutes
iPhone XS	3 hours 20 minutes
iPhone XS Max	3 hours 50 minutes
iPhone XR	3 hours 40 minutes

A few important notes about this table:

This means how long the charging takes from 0 to 100%.
Some models were combined into one line due to the fact that their battery capacity differs very slightly, and it makes no sense to verify the time with an accuracy of minutes.
The data is indicated using a standard (included in the kit) power supply (5 Watt, 1 Ampere current).
All figures are approximate, just for guidance. You can have more or less.

A useful feature! Useful for those who want to charge faster - use airplane mode. In places with an uncertain signal of the cellular network, such an operation will help speed up the process by 20-30%.

It is also important to remember about such things:

Up to 80% of the iPhone is the so-called fast charging, the next 20% is recruited much more slowly.
How long does it take to charge new and newly purchased iPhones? The same as those already used. Without any frills and perversions (like fully charged three times, then discharged to the end, etc.). Modern batteries do not need such calibrations.
Upon reaching full charge no need to run and rush to turn it off. Nothing bad will happen - special controllers are built into the iPhone itself, the power supply unit and even the wire, which will not let the smartphone "oversaturate" with energy and thus deteriorate.
iPhone can be charged many times. Not even that. Many times! Why? Read personal experience about how I, after 2.5 years of use, and what happened to her.

Conclusion: charge the iPhone as much as it (and most importantly, you!) Needs. Don't chase hard numbers and don't make life difficult for yourself.
