It's no secret that over time, the battery level of many gadgets decreases. Therefore, it does not hurt for each owner to get acquainted with how the battery is replaced in a tablet with their own hands. Of course, you can not think too much and use the services of a repair service. But if there is a desire to learn something on your own, it never hurts to try. The acquisition of specific simple skills will help not only to understand how to replace the battery in the tablet, but also to spend time with benefit, significantly saving your own budget.
Reasons for battery failure
If there are constant voltage surges in the electrical network, the battery may not be able to cope with a sharp change in current amplitude and periodically malfunctions. In this case, the tablet may turn off suddenly, and then "starts" on its own. Of course, this can significantly reduce battery life.
Some types of lithium-based batteries have a relatively short life, despite other advantages. The capacity of the battery decreases over time and should therefore be replaced.
Damage to the tablet battery itself may also occur due to temperature changes or increased current load when using especially powerful devices for charging gadgets.
How to choose the right battery
Before buying a battery, you need to understand what kind of power source was installed in the device before. As a rule, this is written on the battery itself. Usually, the vast majority of gadgets have lithium-based batteries: lithium polymer (Li-pol) or lithium-ion (Li-ion).
Also, before purchasing, you should know the exact size of the battery, so if in doubt, it is better to show the old battery to the seller as a sample. For curiosity, you can measure the battery yourself, finding out what its length, width and thickness are, in order to know exactly all the necessary parameters in the future.
The battery capacity is selected either the same as that of the old one, or you can take a battery with larger capacity but the same size as before. At a cost, it will cost more, but the tablet will work much longer. Batteries that are standard in inexpensive tablets have a maximum capacity of 4000 mAh.
In order not to have to change the power source again and again, it is better to purchase a battery with a capacity of at least twice the previous one. Experts in the field of electronics advise even to purchase a cell with a minimum capacity of 7000 mAh.
Due to the fact that the market offers a huge number of tablets different modifications may have trouble finding desired battery. Power supplies with increased level capacities are sold in specialized online stores, or you can contact any author of popular articles on the topic of electronics repair, which can help in purchasing the right battery.
Replacing the battery in a Samsung tablet
Unlike other cheaper Chinese models, changing the battery for Samsung is quite simple. This will not be difficult even for a beginner, since replacing the battery on a tablet is more High Quality always occurs without spending additional effort and using a minimum number of tools or improvised means. You will need a Phillips screwdriver, a plastic spatula and tweezers.
To remove the battery, you must first disconnect the display from the body of the gadget, using a plastic spatula. It is removed easily, it is only important to make sure that you pry the latches in the corners in time to avoid damage due to negligence.
Inside the tablet, several stickers will be immediately visible that protect the cable. Stickers are removed with tweezers, the latches of the loops open and are removed. Using a standard Phillips screwdriver, the screws that hold the battery are unscrewed. The old battery is removed, a similar new one is installed in its place. There should be eight screws fixing the battery inside the tablet.
The speed of work and the very process of installing a power source in a Samsung tablet is also simplified due to the fact that there is no need to solder the wires with a soldering iron: the battery itself is equipped with a plastic plug that covers the wires, which is easily inserted into a special “socket” on the motherboard.
After installing a new battery, the cable must be carefully snapped back, pressing lightly and not forgetting about the corners.
Replacing the battery in a "budget" Chinese-made tablet
The process of replacing the battery in such gadgets is possible on your own, but it will be much more risky and time-consuming due to the fact that ordinary Chinese manufacturers often very casually refer to the internal "stuffing" of the tablet. Of course, the cost of such a device is an order of magnitude lower than that of the same Samsung, but do-it-yourself repair can turn into a solution to a fragile technical puzzle. For example, one has to carefully and scrupulously understand where is going this or that posting, or pretty tinker with removing the cover.
When working with many Chinese gadgets, the question always arises whether it is possible to change the battery on a tablet, which, at first glance, is not possible to open. Getting to the battery itself can be difficult: it seems that the screen is tightly attached to the case, and flimsy plastic latches go tight and can break when pressed hard. However, craftsmen in the field of electronics suggest using a regular plastic card. With its help, it is quite possible to remove the battery without damaging the device itself.
First, you should carefully inspect the gadget, visually "testing" it for at least a small gap (slot) between the display and the case. You can carefully try to pry the gap with your fingernail, ensuring that it becomes sufficient for a plastic card to penetrate into it. Insert the card into the slot, swipe it around the entire perimeter of the tablet, trying to raise the display. Pry off the corners of the device with a card, carefully opening all possible latches. As soon as the tablet is almost completely opened, carefully detach the display from the case with your hands.
Most often, the battery in such devices is attached to double-sided tape. To remove it from the device, you need to lightly pry it with a card from below and pull it up. In this case, you should pay attention to the fact that the battery is soldered to the motherboard with two wires. Gotta remember them correct position- this will be needed when installing a new power supply.
After removing the old battery from the device, the insulation is removed from both wires of the new one, then it will be necessary to tin them with a soldering iron and solder them correctly to the board, remembering that red wires are "+" and black wires are "-" . After that, check the soldering of the contacts with a magnifying glass to avoid a short circuit.
The new battery is placed in the same place. First, carefully fold the wires, then the battery, then, pressing it lightly, glue it with double-sided tape, fix all the removed cables, including the WiFi antenna.
Among similar options there is also a series of "Bliss" from Nexus. If the question arises of how to change the battery on a tablet of this type, the presence of screws at the end of the device can “save” the situation. To wield a plastic card in this case you don’t have to, because its body can be removed easily with a screwdriver. Inside, Bliss looks almost the same as many Chinese counterparts, all its wiring, including battery contacts, are soldered to the system board.
Before you finally close the tablet, it is advisable to check the operation of the buttons and the presence of backlash in the motherboard. You can immediately turn on the device and check its operation. If the tablet does not turn on, it's okay: most likely, the battery may not be sufficiently charged. The battery should be charged, and the gadget will be ready for use again.
Have you noticed that your favorite - iPhone 5th model, began to discharge too quickly? There are two options. Either recently you have begun to use it too actively, or the battery has lost a certain percentage of capacity over time and now it needs to be changed. Apple technology is, first of all, a brand known throughout the world. And only then smartphones and tablets. That is why the cost of replacing the battery in service centers can sometimes be equated to extortionate. In this regard, we decided to write for you detailed instructions, where it is intelligibly told and clearly shown how to change the battery on an iPhone 5.
How to change the battery on iPhone 5
We want to say right away that the process is not easy. And if you have not previously carried out such procedures, it is better not to risk the safety of your device, its performance and take the gadget to a service center. There, the battery will be replaced by professionals who have successfully repaired far from one hundred smartphones. Ready to take a risk and confident in your abilities? Then let's get started!First, let's define what we need. So, for self-replacing the battery, we need a set of small screwdrivers that are designed to unscrew very small bolts. It is also better to get plastic tools and a suction cup - they are needed for smooth and harmless disconnection of contacts, modules. These are sold in specialized stores.
Disassembling the iPhone 5 case to replace the battery
Well, now the fun begins - the parsing process. Be extremely careful, careful and as vigilant as possible. You must do the following:Basically, too complicated process You can’t name battery changes on the 5th iPhone. Rather, it requires scrupulousness and accuracy, otherwise it will be possible to lose the full functionality of the gadget.
Theoretical life limit for iPhone batteries is 400-500 full charge-discharge cycles. After that, 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 "planted" in less than a year. Let's see how you can change the battery to various models iPhone smartphones.
When is it time to change your iPhone battery?
Battery swollen
First, let's decide whether it is worth changing the battery? The first sign can be seen and felt physically - the battery began to "swell". Gases accumulate under the shell of the battery, which increase its volume. It should be noted that battery swelling is not related to long term service - even after 10 years of continuous operation, the battery should not swell 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, the accumulated gases are explosive and can detonate on impact. If you are not confident in your abilities, do not change it yourself - carry it to a service center.
In all generations of the 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 the back panel sticks out a little or even cracks under the pressure of the increased battery. In aluminum and glass iPhones, battery swelling is reflected on the screen of the device. If a bulge forms on it, and pressing causes liquid crystal stains and creaks, then we can talk about swelling of the battery.
Phone drains quickly
With this point, everything is obvious - if the phone starts 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? Do not rely on intuition - rely on specific numbers in the smartphone settings. There is a separate item "Battery", in which you can study the statistics of charge consumption and the operating time of the device from the last full charge.
On Apple smartphones, it is possible to see exact statistics, how many percent of the capacity the battery has lost over the entire period of 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 similar, designed to receive complete information about the device). It is easy to understand how the program works: just put it on your computer, run it and connect your iPhone via USB. iBackUpBot will connect to your phone and display all 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 in percent.
The More Info window has battery usage statistics
What tools will be needed
If you want to do everything the way Apple intended, then you will need a branded screwdriver for the pentalobe bolts that are located on the bottom of the smartphone; iSlack device - a kind of pliers, only with suction cups (for removing the screen); original Apple battery for your device model.
iSlack - iPhone Disassembly Tool
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 order any suction cup there that would be convenient to attach to the screen, so that you can then carefully lift it up. You can even find a plausible copy of iSlack if you search hard enough.
That's all: no more lotions are required. In fact, there are only two tools. Now let's talk about how to still replace the battery of the device.
How to replace the battery on iPhone 4/4s, 5/5s, 6/6s, 7
It should be said right away that The best way changing the battery on the iPhone is taking the device to a service center. The cost of such work is 1500 - 3000 rubles. If you do not feel sorry for money or you 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 energy, 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 parsed somewhat differently.
How to change battery on iPhone 4/4s
- The first thing to do is unscrew the two screws on the bottom of the device. On the sides of the connector 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 recess 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 three millimeters, and then use the 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 with your hands. But do it very carefully and carefully so as not to damage the device. Place your phone face down in front of you. It is recommended to put something soft under the display, so as not to scratch it later, since to remove the battery, you will have to tinker a lot.
To remove the cover, slide it slightly away from you.
- Now you need to disconnect the battery. Remove the small Phillips screw that nailed the battery to the smartphone's motherboard. Then gently grab the silver connector and very gently pull it up and slightly towards the battery. Be careful: there is a black fastener under it, 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 employees experience at the word Apple. You might even hate Apple. In general, the battery is glued to the case, and to pull it out, you need to pull on the plastic tab while prying the battery 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 hair dryer to heat up the glue to make it more pliable. But don't overheat the device. Having finally unfastened the battery, do not rush to clean the glue: you can put a new battery on it.
Pull out the plastic tab to remove the battery
- Final stage. Clean the case, connect a new battery and assemble the device.
iPhone 5/5s
- We start, as in the case of the iPhone 4/4s, by unscrewing the screws on the bottom of the smartphone.
Loosen the two screws to release the screen
- Now you need to lift the screen, and not the back cover, like the iPhone 4/4s. To do this, 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 body of the device, you need to disconnect the cable connecting it to motherboard. Gently pry up on the connector and unhook the Home button connector.
Insert the device into the recess on the tool and attach the suction cups
After sticking the suction cups, gently press the handles to lift the screen
Unfasten the connector cover
Disconnect connector
Now the screen can be raised
- The screen can now be lifted off the device. But the display is still attached to the case at the top of the device.. Take Phillips screwdriver and unscrew the four screws that hold the silver cover. Under it, you will find the connectors that fasten the display to the device. Pry them with a soft tool and remove the display from the device. After these operations, you can remove the screen away. Let's take care of the battery.
Disconnect connector
By 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.
Loosen the screws and remove the metal plate
Disconnect the plug from the board
- Now slightly pull out the black plastic tab. Cut it in half. Now gently grasp one half and pull it up. You will see a cloudy stretching film. Pull it around the battery as if you were trying to pull out a rope stuck under something heavy. After pulling out the film completely, repeat the same with the second half of the black tongue.
Cut tongue in half
Pull the tape out from under the battery
- Once you've removed both halves of the film, pry up on 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 hair dryer

iPhone 6/6s
Replacing the battery on the iPhone 6 and iPhone 6S is similar in all of its steps to replacing the battery on the 5th generation iPhone. You can use the same tools. Unless iSlack has to buy another one if you use it.
- We unscrew the two pentalobe bolts from the bottom of the device. On the sides of the Lightning port. We take a star-shaped screwdriver and do everything as always.
- Now we take the screen. Use iSlack or a combination of something thin and soft and a suction cup. Raise the screen from the side of the Home button.
Raise the screen with iSlack
Do not rush to remove the screen completely - the display is still attached to the motherboard! - We take a Phillips screwdriver and unscrew the bolts holding the silvery metal plate under which the display connectors rest. We remove the plate, disconnect the display, remove the smartphone screen away. In the same way, we unscrew the screws at the metal cover covering the battery connector. Disconnect the battery from the motherboard.
Unscrew the bolts on the metal plate and remove the connectors
Loosen the screws on the metal plate and remove the battery connector
- Now it’s worth warming 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 tongue, cut it into two halves, and then pull out each half separately.
Pull the adhesive tape out from under the battery
- After these operations, the battery can be removed. We put the new battery in place, connect the connector to it and assemble the smartphone in the reverse order to this one.
Video subtitle: How to change the battery on iPhone 6s?
iPhone 7 and iPhone 7 Plus
iPhone 7 and 7 Plus repair differs from 6th and 6s generations in just one step. Among other things, you will need to disconnect the Taptic Engine, which interferes with the removal of the battery.
In case you didn't know: in the 7th generation iPhone Apple abandoned the mechanical Home key. Instead, in a round edging is a touch key, equipped with tactile feedback. And the vibration motor responsible for this was called the Taptic Engine. " Given name some kind of vibration motor there? - could well pop up in your head. However, oddly enough, such an honor is fully justified, because the language will not turn around 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 pressing. Strange and indescribable sensations, but Apple fans, as usual, are delighted.
- So. First, of course, unscrew the two pentalobe screws on the bottom of the device.
Loosen the screws on the bottom of the device
- Then, using a suction cup and a soft, thin screwdriver or an iSlack tool, pry the screen up as gently as possible above the Home button. iFixit recommends warming up the device before starting disassembly. Use a hair dryer 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 hard, trying to move it away, you can break the connecting tires. For convenience, let's detach the screen from the case. To do this, unscrew the screws at 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, you can put it aside. Now unscrew the Taptic Engine, as it prevents us from disconnecting the battery from the board. And before you detach the Taptic Engine, you need to unscrew the screws from the black plastic cap. After removing the cover, disconnect the battery connector that was hidden under it.
Pull out 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 reverse order.
Problems that may arise
Loss of efficiency
The worst thing that can happen if you disassemble the device yourself is the loss of performance: 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 jambs of your crooked hands. However, you should not panic right away. Perhaps you just missed something, forgot to connect some kind of connector. Disassemble the device again, go over all the points in the instructions and make sure that every bolt is screwed in and every plug is connected. There is a possibility that the battery you bought is damaged or does not fit your iPhone model. This often happens if you buy cheap, non-original batteries.
If something like this happened: deal with the hardware or take the phone to a service center. Some useful tips:
- If the Home button and the conversational microphone stop working, then the problem is localized in the lower cable of the device. Recheck the connectors on the bottom of the device.
- If the screen began to shimmer when pressed, it means that the battery is not tight: something sticks out and pushes through the screen. Either you did not install the battery carefully enough, or the battery does not fit your device model.
- iPhone started shutting down and restarting randomly. The problem is most likely a damaged motherboard. Most often, the problem occurs due to the fact that the screws were mixed up during assembly. The longer ones were planted in place of the shorter ones, causing damage. Disassemble and reassemble the device, carefully examining the fasteners. If you're 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 in service center Apple voids warranty. And no, it will not work to deceive service centers. Apple, like many other manufacturers, implants special sensors into the device. And if the device is opened, then the counter inside the sensor increases. Service center employees reset this sensor, but for this you will have to thoroughly hack operating system. But why do it? 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 accuracy of the devil is necessary in this matter, otherwise the device may be damaged. And do not forget that any unauthorized opening of the device leads to a loss of warranty. So if your phone was recently purchased, try to get a free battery replacement at a service center, or wait until the expiration date warranty service won't end.
At battery the car has a certain operating period. When it becomes unusable, you have to replace it. After purchasing a suitable battery from a reliable supplier, such as 1AK-M, you should think about how to properly replace it. Basically, this procedure cannot be called complex. Everything is done quite simply, so even a novice motorist can cope with such work.
Important Points
To replace old battery on a new one, you will need to prepare a pair of open-end wrenches in advance.
All work should be done with gloves. Thus, it will be possible to protect the skin on the hands from possible burns. It is best to use rubber gloves for these purposes so that the liquid cannot directly contact the skin.
Removing the old battery
At the very beginning, you need to turn off the engine and turn off the electrics in the car. Before pulling the battery out of the car, it is worth removing the negative terminal with an open-end wrench. Then the positive terminal is removed. You need to disconnect the wires so that there is no short circuit. Some models of batteries are attached from below, but there are also those that are fixed from above.
If the vehicle is equipped big amount electronics, it is undesirable to turn off the power in it, because all settings will be reset. To prevent this, you must additionally connect a second battery.
How to install a new battery?
Before you start installing a new battery in a car, you first need to clean the terminals from rust and dirt. Cleaning is done with sandpaper or a brush for metal.
Next, the battery is put back. Only all manipulations must be performed in reverse order. After installing the battery, fixed fasteners. Then the positive terminal is connected and then the negative one. In order to protect the terminals from premature corrosion, it is recommended to pre-coat them special tool. Today, such compounds are presented in the form of gels or liquids, they can be purchased at any car dealer. Finally, the operation of all systems is checked and the engine is turned on.
After getting acquainted with detailed information Regarding replacing the battery in the car, you can try to do everything yourself. After all, such work does not present any particular difficulties.
Perhaps, few of the motorists have passed the “this cup” - a battery that has failed at the most inopportune moment. Especially unpleasant similar situation V winter time when the battery is most exposed to critical temperatures and, having exhausted the reserve, is finally discharged. How to act in such a situation? There is only one answer: go to the nearest auto shop and buy a new battery. After purchasing the battery, you will need to install it. There are two options here - tow the car to the nearest service station, or replace the battery with your own hands. With the first option, everything is clear, but how to replace car battery not everyone knows on their own. Today we will talk about this, simple in general, operation.
To begin with, you will have to purchase a battery that is suitable in size and, most importantly, performance. You can buy exactly the same battery as you installed, or you can buy another manufacturer. It happens that it is difficult to find a complete analogue of your battery in the store, and therefore you have to choose from what is available. We will not name specific battery manufacturers - the leaders of this market can be found in any search engine. By the way, there you can also pick up a battery that meets all your parameters, as well as find out if such a product is available in the store where you are going to go shopping.
Suppose the process of acquiring a battery was successful, and you brought it to the car. Now let's install a new battery, having previously removed the old one. To do this, you will need wrenches of different calibers, a screwdriver and rubberized gloves. Before disconnecting and removing a failed device, let's ask ourselves a question: is there such equipment in the car as a radio, navigator, on-board computer. If at least one of the listed devices is available, we advise you to ask for a loan for another battery, which can be used to power the listed car equipment. This must be done in order to avoid resetting all existing settings and subsequent reprogramming and elimination of errors that may occur when “rebooting” the battery. We connect the second battery before pulling out the old battery. Once back-up power is obtained, the spent battery can be removed. We do this in several steps:
1. . A 10 wrench is usually suitable for this procedure, although some models may have different threads. Therefore, it is important to have a wrench with interchangeable heads on hand.
In fact, there is not much difference in whether we first disconnect the “positive” or “negative” terminals, but automotive electricians recommend starting with the “positive” one, since electricity runs from "positive" to "negative" terminal.
2 . Removing the old battery. At different models Car batteries are installed differently. It happens that in order to dismantle the battery, it is enough to remove the terminals, push the halves of the casing, which protects the battery from external influences, and, pulling the handle, remove the device from the slots. In many modern cars the battery is screwed to the bottom of the casing (to ensure its stability), then you have to sweat, unscrewing the nut that "holds" the battery. To do this, you may need a wrench with a head of 13 and with an extension cord, with which you will need to unscrew the fixing nut. After this operation is completed, move apart the halves of the casing and pull out the battery. Keep in mind that the battery is quite heavy (13 to 20 kg) so you may need some help.
3. Installing a new battery. Before installing new battery, it is necessary to clean the terminals that could be oxidized during long-term operation(Typically, new batteries will last 4-7 years). We clean the terminals with an old toothbrush soaked in a solution of baking soda.
Battery terminals
After that, we carefully install the new battery into the grooves, fasten it, check how firmly it stands in the groove by gently rocking from side to side. Then we put on the clamps. If you removed the "positive" and then the "negative" terminals first, then to new battery first we connect the "negative" terminal, and then the "positive". To prevent the “positive” terminal from sparking when in contact with the battery, we put on it a special plastic cap, which can be purchased with a new battery. To prevent the terminal fasteners from corroding, you can spray them with lithium grease(Litol-24). If your car is equipped with an alarm or central locking, you must open the car doors and remove the key from the ignition before installing a new battery.
After installing the battery, check its operation. To do this, insert the key into the ignition, start the car and check the correct operation of all electronics on board. By the way, you can find out how long, even approximately, a new battery will last - just look at the "minus" of the battery, where the manufacturer stamps two digits, the first of which means a week (can be converted into a month), and the second - the year of production .
