Do-it-yourself marking of iPhone 4 battery outputs

The battery is the Achilles heel of modern smartphones, and the iPhone 4S is no exception. Almost any flagship with active use is discharged to zero every day. This is the price of a compromise, thanks to which today's devices can demonstrate amazing power, have large and clear displays, but at the same time are “packed” into a thin, elegant case, in which for a large battery that can hold a charge during active use, well, at least for a couple of days, there is no place.

The enormous load on the battery leads, however, not only to daily discharge, which users are already accustomed to, but also to rapid wear of the battery, and this is a more serious problem. If you consider that the iPhone 4S, like any other iPhone, has a non-removable battery, and replacing the battery in the service costs a lot of money, it becomes quite sad. However, we hasten to please you - replacing the battery on an iPhone 4S is not such a difficult task, and if you have the proper tools, you can do it yourself.

In this article we will tell you what replacing the battery in an iPhone 4S looks like, and also give detailed instructions, which will help you change your battery yourself. But first, we must explain how to understand that it’s time to change the battery, and also talk about the tools that will be required to perform the procedure for replacing a dead battery on an iPhone 4S smartphone.

Battery aging is not a one-time process; it wears out day after day and in each subsequent cycle the battery discharges a little faster than the previous one. And, in general, this is the norm. However, how can you understand that the situation has gone beyond normal and your smartphone needs a new battery? There are at least two signs that will help you figure it out:

When performing everyday tasks, the battery should not be discharged by several percent at once (however, if you play “heavy” games, this situation may be quite normal and does not indicate that it is time to change the battery).

Advice! For better control batteries, set the digital charge display in your iPhone settings - you can do this in the following way: go to the “Settings” menu, then “General”, “Statistics” and activate the “Charge in percentage” slider.

The smartphone should not turn off spontaneously when the charge is 20% or more (of course, there may be other reasons for this behavior, but if the problem is not with the battery, most likely such unexpected shutdowns will be accompanied by strong heating of the device).

Another telltale sign that it’s time to change the battery on the iPhone 4S is the swelling of the smartphone’s body. The fact is that batteries emit gas during operation. It accumulates under the battery shell and slightly inflates it. But! If the battery is already very old and a lot of gas has accumulated, it will become cramped. Trying to get out, he will begin to “move” everything that is in the way, as a result, cracks may appear on the back cover, or it will simply seem to be slightly raised. In this case, you cannot delay, otherwise more serious repairs will be needed.

What tools are needed to replace the iPhone 4S battery?

In order to change the battery on an iPhone 4S with your own hands, you will need a special kit for disassembling Apple equipment; it can be purchased on sites like Aliexpress, Ebay, etc. for very modest money. As a matter of fact, on these same sites you can new battery buy, but keep in mind that you will have to wait, these sites offer free delivery, but it is quite long.

If the matter is urgent, it is better not to take risks and buy everything you need in a regular offline store that specializes in selling various parts and tools for repairing certain electronics.

Of course, you can do it with various non-special means - you will need two screwdrivers - a Phillips and an asterisk, thin tweezers and a flat spatula - we will use it to pry off the battery. But! A special kit for disassembling Apple equipment has one very huge advantage - most of the tools are plastic, which means that if, due to inexperience, you “stick” into any contact, it will not be damaged, but non-special tools, as a rule, are metal, and there is a risk of causing irreparable harm to the smartphone. In general, we recommend that only professionals use metal non-special tools.

Instructions for changing the iPhone 4S battery yourself

Well, here we actually get to the point. So, how to replace an iPhone battery with your own hands? Here's what you need to do in a nutshell: remove back cover, disconnect the old battery, install a new one and put the cover back. Seems quite simple, right? Well, let's look at the process in detail and step by step:

Take a star screwdriver and unscrew the screws holding the back cover of the iPhone - they are located on either side of the connector into which you insert the charging cord. Don't be afraid to mix up the screws - they are identical.
Are the screws loose? Then we place the smartphone on the table with the screen down and slightly move the cover up, and then remove it.
Now you need to unscrew the screw that secures the battery connector; for this you will need a Phillips screwdriver.
The connector is free - unclip it - a flat spatula will help.
Now look carefully - the small black part is the coaxial cable retainer - you need to pull it out so that it doesn’t get lost while we remove the battery and turn the smartphone back and forth. Remove with tweezers.
Well, it’s time to pull out the battery, to do this we’ll pull the special tab - keep in mind that the battery won’t give way so easily, because it’s glued. A flat spatula will also come in handy here; you can safely pry off the battery with it.
Did you manage? Great - now all that remains is to install a new battery in place of the old one and follow all the above instructions in reverse order - return the coaxial cable clamp to its place, latch the connector, secure the latch with screws, put on the cover and tighten the screws holding it in place.
That's it - you've done it!

By the way, these instructions will also work for replacing the battery on an iPhone 4!

Let's summarize

As you can see, changing an iPhone battery is really not difficult, but, of course, being careful is very important. IN modern smartphones All the “hardware” is packed as tightly as possible - the thin case obliges you, and therefore you need to act extremely carefully and work with special tools so as not to damage anything. And finally, a very important piece of advice - if you are even a little unsure of your abilities, go to the service!

If your iPhone 4 begins to perform noticeably worse in offline mode, then most likely its battery has lost its properties (). Fortunately, replacing the battery on an iPhone 4 is not the most difficult process, and can be done at home. Detailed Process disassembling the iPhone 4 and replacing the smartphone battery was discussed in this manual.

The theoretical life limit of iPhone batteries: 400–500 complete charge-discharge cycles. After this, the battery loses more than 20% of its capacity. In practice (due to improper battery care and non-compliance with the rules of use) much less. If we take into account the standard mode of using the phone - discharging it to zero during the day and charging it every night - then the battery can be drained in less than a year. Let's figure out how to change the battery to various models iPhone smartphones.

When is it time to change the battery on your iPhone?

The battery is swollen

First, let's decide whether it's worth changing the battery? The first sign can be seen and felt physically - the battery has begun to “swell”. Gases accumulate under the battery shell, which increase its volume. It is worth noting that swelling of the battery is not associated with a long service life - even after 10 years of continuous operation, the battery should not inflate like a balloon. Most often this is a consequence of external damage to the battery. For example, if you hit him or dropped him on the floor. Be careful, accumulated gases are explosive and may detonate on impact. If you are not confident in your abilities, do not change it yourself - carry it to service center.

In all generations of iPhone, the back cover is not removable, so it is not so easy to notice the swelling of the battery. However, it is possible. In plastic models you can feel that back panel it bulges somewhat or even cracks under the pressure of the increased battery volume. In aluminum and glass iPhones, the swelling of the battery is reflected on the screen of the device. If a bulge forms on it, and pressing causes liquid crystal stains and creaking, then we can talk about swelling of the battery.

The phone runs out quickly

With this point, everything is obvious - if the phone begins to discharge faster than in the first months after purchase, then you need to change the battery. However, it is always worth remembering the psychological factor: maybe it just seems to you that it is quickly discharged? Don't rely on intuition - rely on specific numbers in your smartphone settings. There is a separate “Battery” item, where you can study the statistics of charge consumption and the operating time of the device since the last full charge.

On Apple smartphones, it is possible to view accurate statistics of how many percent of capacity the battery has lost during its entire operation. iPhones collect information about charge-discharge cycles and analyze it. The prepared data is intended for service center employees, so to see it, you need to install the iBackupBot program (or a similar one designed to receive complete information about the device). It’s not difficult to understand how the program works: just install it on your computer, launch it and connect your iPhone via USB. iBackUpBot will connect to your phone itself and display all the collected data. Click on the More Information link, a window with detailed device parameters will open. In the Battery section, find the line BatteryCurrentCapacity: this number is the battery capacity as a percentage.

The More Info window has battery usage statistics

What tools will you need?

If you want to do everything the way Apple intended, then you will need a proprietary screwdriver for the pentalobe bolts that are located on the bottom edge of the smartphone; iSlack device - a kind of pliers, only with suction cups (for removing the screen); original accumulator battery Apple for your device model.

iSlack - iPhone disassembly tool

The suction cup can be used instead of iSlack

If you don’t want to overpay for branded tools, then you can buy Chinese screwdrivers somewhere on AliExpress, and also order any suction cup there that would be convenient to attach to the screen, so that you can then carefully lift it. You can even find a plausible copy of iSlack if you look hard enough.

That's all: no more bells and whistles are required. Essentially, just two tools. Now let's talk about how to replace the device's battery.

How to replace the battery on iPhone 4/4s, 5/5s, 6/6s, 7

It’s worth saying right away that The best way Changing the battery on an iPhone means taking the device to a service center. The cost of such work is 1500 - 3000 rubles. If you don't mind the money or are not confident in yourself, it is better to turn to professionals. Especially if your device is still under warranty.

Well, if you are confident and full of strength, let's figure out how to replace the battery correctly. G The main thing: do not forget to turn off the device before you start disassembling it!

The principle is similar for all iPhone models starting from model 5. 4 and 4s are dealt with slightly differently.

How to change the battery on iPhone 4/4s

The first thing to do is unscrew the two screws on the bottom edge of the device. On the sides there are connectors for charging and connecting to a computer. The base of the screw does not have a straight or cross-shaped recess, but a special, star-shaped one. This type of notch is officially called Pentalobe, such screwdrivers can be found in online stores iFixit, eBay, AliExpress and others.
First you need to unscrew the two screws on the bottom edge
The next step is to remove the back cover. Slide the lid away from you about three millimeters, and then use a suction cup or iSlack to lift it up. If you are not well prepared and you do not have such devices at hand, you can try to remove the cover by hand. But do it very carefully and carefully so as not to damage the device. Place the phone in front of you with the display facing down. It is recommended to place something soft under the display so as not to scratch it later, since removing the battery will require a lot of fiddling.
To remove the cover, move it slightly away from you
Now you need to disconnect the battery. Remove the small Phillips screw that secures the battery to the smartphone's motherboard. Then carefully grab the silver connector and very carefully pull it up and slightly towards the battery. Be careful: underneath there is a black fastening element, and if this element bends, it will be very, very bad.
Disconnect the battery connector from the board
Now let's remove the battery. Perhaps at this stage you will feel all the pain that service center workers feel when they hear the word Apple. You might even end up hating Apple. Basically, the battery is glued to the case, and to remove it, you need to pull the plastic tab while prying the battery up with something thin. It is glued tightly, so you need to pull hard, but at the same time try not to tear all the insides of the iPhone. You can use a hairdryer to heat the glue to make it more pliable. But don't overheat the device. Having finally detached the battery, do not rush to clean the glue: you can put new battery.
Pull out the plastic tab to remove the battery
Final stage. Clean the case, connect a new battery and reassemble the device.

iPhone 5/5s

We start, as in the case of the iPhone 4/4s, by unscrewing the screws on the bottom edge of the smartphone.
Remove the two screws to release the screen
Now you need to lift the screen, not the back cover, like the iPhone 4/4s. To do this, we use iSlack or a combination of a suction cup and some thin and soft tool to pry the screen from below. Be careful not to damage the Home button. Then, when the screen is slightly raised above the device body, you need to disconnect the cable connecting it to motherboard. Carefully pry the connector and unhook the Home button connector.
Insert the device into the recess on the tool and secure the suction cups
After attaching the suction cups, gently press down on the handles to lift the screen
Unfasten the connector cover
Disconnect the connector
The screen can now be raised
The screen can now be lifted off the device. But the display is still attached to the body at the top of the device. Take a Phillips screwdriver and remove the four screws holding the silver cover in place. Under it you will find connectors connecting the display to the device. Pry them with a soft tool and disconnect the display from the device. After these operations, you can move the screen away. Let's take care of the battery.
Disconnect the connector
After disconnecting all connectors, you can move the screen to the side
First, disconnect the battery from the board. To do this, unscrew another metal plate below the battery. Then pry up the connector and disconnect it from the board.
Unscrew the bolts and remove the metal plate
Disconnect the plug from the board
Now slightly pull out the black plastic tab. Cut it in half. Now carefully grab one half and pull it up. You will see a cloudy, stretchy film. Pull it around the battery as if you were trying to pull out a rope stuck under something heavy. Having pulled out the film completely, repeat the same with the second half of the black tongue.
Cut the tongue in half
Pull the tape out from under the battery
Once you have removed both halves of the film, pry up the battery and pull it out. Install a new one in its place and assemble the device.
Remove the battery after heating it with a hairdryer

iPhone 6/6s

Replacing the battery on the iPhone 6 and iPhone 6S is similar in all its steps to replacing the battery on the 5th generation iPhone. The same tools can be used. Unless you have to buy another iSlack if you use it.

Unscrew the two pentalobe bolts from the bottom edge of the device. On the sides of the Lightning port. Take a torx screwdriver and do everything as always.
Now we remove the screen. We use iSlack or a combination of something thin and soft and a suction cup. Raise the screen from the side of the Home button.
Use iSlack to raise your screen
Do not rush to remove the screen completely - the display is still attached to the motherboard!
Take a Phillips screwdriver and unscrew the bolts holding the silver metal plate under which the display connectors rest. We remove the plate, disconnect the display, and move the smartphone screen away. In the same way, unscrew the screws from the metal cover covering the battery connector. Disconnect the battery from the motherboard.
Unscrew the bolts on the metal plate and remove the connectors
Unscrew the bolts on the metal plate and remove the battery connector
Now you should warm up the battery with a hairdryer so that the glue acquires a more pliable consistency. Like the iPhone 5/5s, the sixth-generation iPhone's battery is held in place by adhesive tape. We take out the plastic tab, cut it into two halves, and then pull out each half separately.
Pull the adhesive tape from under the battery
After these operations, the battery can be removed. We put the new battery in place, connect its connector and assemble the smartphone in the reverse sequence to this one.

iPhone 7 and iPhone 7 Plus

Repairing iPhone 7 and 7 Plus differs from the 6th and 6s generations in just one step. Among other things, you will need to disconnect the Taptic Engine, which prevents the battery from being removed.

If you didn't know: in the 7th generation iPhone Apple abandoned the mechanical Home key. Instead, in the round frame there is a touch key equipped with tactile feedback. And the vibration motor responsible for this was called Taptic Engine. “Some kind of vibration motor has its own name?” - could well pop up in your head. However, oddly enough, such an honor is fully justified, because it would be hard to call the Taptic Engine an ordinary vibration motor. Its action resembles not so much a vibration as a push, which gives a certain feeling of the depth of pressure. It’s a strange and difficult to describe feeling, but Apple fans, as usual, are delighted.

So. To begin, of course, unscrew the two pentalobe screws on the bottom edge of the device.
Unscrew the screws on the bottom edge of the device
Then, using a suction cup and a soft, thin screwdriver or iSlack, pry the screen up above the Home button as gently as possible. Experts from iFixit recommend warming up the device before starting disassembly. Use a hairdryer for this, but make sure that the device does not overheat.
Disconnect the connectors from the board
Remember that the display is still attached to the motherboard! If you pull it too hard, trying to move it away, you can break the connecting tires. For convenience, let's disconnect the screen from the body. To do this, unscrew the screws from the two metal plates under which the cords from the screen go, and then disconnect the plugs from the board. Don't forget to be careful.
Now that the screen is not attached to the body in any way, you can put it aside. Now let's unscrew the Taptic Engine, since it prevents us from disconnecting the battery from the board. And before you unfasten the Taptic Engine, you need to unscrew the screws on the black plastic cover. After removing the cap, disconnect the battery connector that was hidden under it.
Pull the tape to release the battery
Now the battery is no longer secured by anything: you can remove it and put a new one in its place. Connect it to the board and assemble the smartphone in the reverse order to this.

Problems that may arise

Loss of performance

The worst that can happen if you disassemble the device yourself is loss of functionality: partial or complete. If you decide to do everything on your own, then you are your own guarantee. So you will have to compensate for the mistakes of your crooked hands. However, there is no need to panic right away. Perhaps you just missed something, forgot to connect some connector. Disassemble the device again, go through all the instructions and make sure that every bolt is screwed in and every plug is connected. There is a possibility that the battery you purchased is damaged or does not fit your iPhone model. This often happens if you buy cheap, non-original batteries.

If something like this happens: deal with the hardware or take the phone to a service center. Some useful tips:

If it stops working Home button and a conversational microphone, then the problem is localized in the lower cable of the device. Double-check the connectors on the bottom of the device.
If the screen begins to shimmer when pressed, it means that the battery is not lying tightly: something is sticking out and pressing through the screen. Either you did not install the battery carefully enough, or the battery does not fit your device model.
The iPhone began to turn off and reboot spontaneously. The problem is most likely a damaged motherboard. Most often the problem occurs because the screws were mixed up during assembly. Longer ones were planted in place of shorter ones, which led to damage. Disassemble and reassemble the device, carefully examining the fastenings. If you are lucky, the device will work as it should. If not, the damage is irreversible and the board needs to be replaced.

Loss of warranty

Of course, if the repair was not carried out by an Apple service center, the warranty will be void. And no, you won’t be able to fool service centers. Apple, like many other manufacturers, implants special sensors into the device. And if the device is opened, the counter inside the sensor increases. The service center employees will reset this sensor, but for this you will have to thoroughly hack operating system. But why do this? If your phone is under warranty, why didn’t you contact the service center?

So now you know how to replace the battery on your iPhone. Remember that the devil's accuracy is necessary in this matter, otherwise the device may be damaged. And do not forget that any unauthorized opening of the device leads to loss of warranty. So if your phone was purchased recently, try to get a free battery replacement at a service center or wait until the battery expires. warranty service won't end.
