If your iPhone battery no longer makes it through the day, replacing it is usually an easy decision. The harder part is choosing what to replace it with.

Alongside the standard-capacity OEM batteries, repair shops now offer high-capacity options that promise more usable time between charges. Some give a modest increase, while others are capacity much higher than the battery originally fitted to the phone.

At first glance, that sounds simple. In practice, capacity matters alongside cell quality, battery management, temperature control, charge reporting, and long-term stability. Let’s use the REPART iPhone 13 battery as an example, then look at why the capacity increase changes from one iPhone model to another.

What Does "High-Capacity" Really Mean?

The standard iPhone 13 battery is capacity at about 3,227mAh and 12.41Wh. The REPART iPhone 13 high-capacity battery is capacity at 3,450mAh, 3.84V, and 13.25Wh, with a 4.47V charge-limit voltage. That works out to roughly 7% more rated capacity.

Seven percent may not sound dramatic, but for someone who regularly finishes the day with little charge left, even a modest increase can be useful. The important point is that 7% is not a rule for every model.

For example, the iPhone 16 Pro has a standard-capacity figure of 3,582mAh, while a REPART high-capacity option is rated at 3,800mAh. That is an increase of about 6%. The iPhone 16 Pro Max shows a bigger spread. A standard-capacity battery is around 4,685mAh. REPART offers a 5,050mAh TI version and a 5,297mAh Select version, roughly 8% and 13% higher respectively.

Across the wider Select range, REPART lists some batteries with capacity increases of up to 39% compared with standard OEM-spec replacements. So when you see "high-capacity," don't assume a fixed percentage. Check the actual mAh figure for the model you're repairing.

Does More mAh Mean More Runtime?

Usually, the more genuine capacity gives the phone more energy to work with. But a 10% increase in mAh does not guarantee exactly 10% more screen time.

How long an iPhone lasts depends heavily on how it's used.

Watching video at moderate brightness is very different from recording 4K video, gaming, using GPS, or dealing with a poor cellular signal. Screen brightness, background apps, 5G, temperature, and processor load all change power use. That's why it's better to talk about rated capacity rather than promising a fixed number of extra hours.

A 3,450mAh iPhone 13 battery has more rated capacity than a 3,227mAh battery. Assuming both batteries are working properly, that gives the phone a larger energy reserve. The exact difference you notice from day to day will depend on how you use it. The standard iPhone 13 capacity of 3,227mAh and 12.41Wh is also documented by iFixit.

The Battery Chip Matters Too

Capacity gets most of the attention because it's easy to compare. The electronics attached to the cell are less visible, but they have an important job. The REPART iPhone 13 battery uses a TI chip solution with Impedance Track technology. REPART rates the system for 1% state-of-charge precision.

In plain language, the battery-management system is trying to answer one question accurately: how much usable charge is actually left? It's harder than it sounds.

Battery voltage changes with temperature, load, age, and state of charge. Poor fuel gauge can lead to the familiar "ghost percentage" problem, where a phone appears to have plenty of battery left and then drops quickly or shuts down sooner than expected.

TI's Impedance Track approach is designed to estimate remaining capacity using factors such as battery impedance, temperature, discharge behavior, and age.

It doesn't create extra capacity. It helps us track the capacity that's already there more accurately.

What Does Less Than 10µA Standby Consumption Mean?

REPART also specifies less than 10µA static consumption for the battery management board. This does not mean the whole iPhone uses less than 10µA overnight. The phone is still powered by wireless connections, background services, notifications, memory, and other hardware.

The figure refers only to battery-management electronics. Keeping that draw low reduces the energy the battery board uses while the phone is idle. It's a small part of overall battery life, but it shows that efficiency is being considered beyond simply increasing cell capacity.

Temperature Control Still Matters

Lithium-ion batteries don't like extreme heat or cold. Temperature affects charging, available power, and long-term battery health. The REPART iPhone 13 battery includes integrated IC thermal monitoring for real-time temperature control, including low-temperature charging conditions.

That matters because added capacity should not come at the expense of basic protection. A good high-capacity battery needs to balance energy density with stable charging and discharge behavior. A bigger mAh number isn't automatically better if the battery management system or cell quality is poor.

Does a High-Capacity Battery Wear Out Faster?

Not necessarily.

Battery aging is affected by heat, charge cycles, charging conditions, storage, cell chemistry, and manufacturing quality. Two batteries with the same capacity can age very differently. REPART describes its iPhone 13 battery as using a Pure Cobalt cell, intended to provide stable chemistry and slow capacity degradation.

That's useful to know, but specific lifespan promises still need long-term test data. For repair shops, the practical question isn't just how many mAh are printed on the label. It's whether the battery combines useful capacity with dependable fuel gauging, temperature monitoring, low board consumption, and consistent cell quality.

So, Is a High-Capacity iPhone Battery Worth It?

If the phone already needs battery replacement, a high-capacity option can be a sensible upgrade. For the iPhone 13, the jump from 3,227mAh to 3,450mAh is about 7%. On other models, the increase may be smaller or considerably larger.

The iPhone 16 Pro Max, for example, can move from around 4,685mAh to 5,050mAh or 5,297mAh depending on the REPART battery series. For a light user, the difference may be modest. For someone spending the day on calls, navigation, video, social apps, or mobile work, extra stored energy can be useful.

The same applies to repair shops.

A standard-capacity battery remains the straightforward replacement, while a high-capacity version gives customers an upgrade option when longer runtime matters to them.

It also gives technicians a clearer way to offer different levels of replacement instead of treating every battery as essentially the same product.

Don't Choose a Battery by Capacity Alone

This is probably the most important point. A battery with the biggest mAh number isn't automatically the best battery. If the cell quality is poor, the fuel gauge is inaccurate, or the battery-management board draws too much power or doesn't handle temperature properly, the extra capacity won't mean much. That's why the specifications behind the numbers matter.

With the REPART iPhone 13 battery, the 3,450mAh capacity is only one part of the story. The TI chip solution, Impedance Track fuel gauging, low static board consumption, thermal monitoring, and Pure Cobalt cells are there to support how the battery operates in everyday use.

For a repair shop or refurbisher, those details can matter just as much as the capacity increase itself.

The Bottom Line

High-capacity iPhone batteries can provide longer use between charges, but the improvement isn't the same for every model. The best way to judge one is to look past the words "high-capacity." Check the actual mAh increase, cell quality, battery-management system, temperature monitoring, and how accurately the battery reports its remaining charge.

For REPART's iPhone 13 battery, the 3,450mAh rating provides roughly 7% more nominal capacity than the standard 3,227mAh figure. Other models can offer different gains, and some batteries in REPART's wider high-capacity range are rated considerably higher than standard-capacity replacements. So rather than thinking of a high-capacity battery as a miracle upgrade, think of it as something more practical: more stored energy, with the electronics and cell design needed to manage that energy properly.

An iPhone battery is three things at once: a lithium cell (the energy store), a Battery Management System (BMS) board that manages charging, and an authentication IC the chip iOS uses to verify the part is genuine. Each tier handles all three differently.

iPhone Battery Comparison

A battery consists of three parts: a lithium cell (the energy store), a battery management system (BMS) board for charging, and an authentication chip for checking authenticity. All three are handled differently by each tier.

*Apple extended design cycle life from 500 cycles (iPhone 14 and earlier) to 1,000 cycles for iPhone 15 and later a meaningful improvement most buyers overlook.

What is a diagnostic-compatible battery?

Batteries manufactured by third-party iPhone parts brands like REWA include a proprietary authentication chip pre-programmed to pass iOS' encrypted hardware handshake. Therefore, health reports are accurate, warnings aren't persistent, and there is no need to transfer chips.

The BMS Authentication Problem

Since iPhone XS, Apple batteries contain an authentication IC that performs an encrypted handshake with the logic board. Whenever the handshake fails, iOS disables the Battery Health display and flags the part as incompatible, mismatched, or absent. There are two types of aftermarket iPhone batteries: ones without the IC entirely and those with a generic IC that fails the check. The battery still charges and works, but its health data is permanently unavailable.

The Used-Pull Nuance

A used-pull battery is a genuine Apple battery that has already been installed and used in another iPhone. On supported models, iOS can verify the battery as a genuine Apple part after the repair and calibration process is completed. For iPhone 15 and later running iOS 18 or later, Settings will show the battery as "Used" rather than new.

Because the battery has already been used, its battery health, cycle count, and first-use history don’t reset when it is moved to another phone. So if a supplier sells a battery at 85% health, that means the battery has already degraded to roughly 85% of its original maximum capacity it is not equivalent to a new battery. Apple also notes that previously used parts can have inconsistent performance depending on their prior use and condition.

For that reason, always buy used-pull batteries from a trusted supplier with clear grading standards, and check the reported battery health, cycle count, physical condition, and warranty whenever possible.

iPhone Screen Comparison

An iPhone screen replacement involves more than simply swapping the glass and display. The overall result depends on the display technology and quality, such as OLED or LCD, the touch and display electronics that control how the screen communicates with the iPhone, and the calibration data used for features such as True Tone, brightness, and color accuracy. Apple calibrates genuine replacement displays through its repair process, and on supported models Repair Assistant installs the required calibration data after installation.

Lower-quality aftermarket screens may still work, but they can differ noticeably in brightness, color accuracy, touch response, power consumption, and True Tone performance. In practice, each screen tier handles these areas differently, which is why two replacement displays that look similar on paper can provide very different everyday experiences.

Why LCD is a Downgrade on iPhone 12 and Later

Starting with the iPhone 12, Apple moved its main iPhone lineup to OLED displays, while the iPhone SE continued using LCD. That means an “LCD screen for iPhone 14” is an aftermarket conversion rather than a replacement that matches the display technology Apple originally designed for the phone.

These budget LCD replacements can still make the phone usable and may cost considerably less, but they generally cannot match a good OLED for deep blacks, contrast, color quality, brightness, and viewing experience. OLED pixels can also switch off individually when displaying black, while an LCD relies on a backlight that remains powered, so Dark Mode does not provide the same display power-saving advantage as an LCD replacement.

Exact brightness varies widely between aftermarket screens, so it is better to judge a specific panel by its tested specifications rather than assuming every budget LCD falls within a fixed unit range. Apple continues to use OLED displays in its new iPhone 17 models as well.

Soft OLED vs. Hard OLED vs. LCD

Apple introduced OLED with the iPhone X, and its modern OLED iPhone displays use flexible panel construction rather than the rigid glass-substrate panels commonly sold as hard OLED replacements. In the repair market, soft OLED generally refers to an OLED built on a flexible plastic substrate, which can better tolerate bending and impact than a rigid glass-based hard OLED panel.

Hard OLED screens are usually cheaper, but their rigid construction makes the display layer more vulnerable to cracking after a drop. LCD replacements work differently: they need a backlight behind the entire panel, so they cannot switch individual pixels completely off for true black, are typically thicker, and do not get the same dark-screen power-saving advantage as OLED, where each pixel produces its own light. 

The Diagnostic-Compatible Screen Breakthrough

REWA's  diagnostic-compatible aftermarket iPhone screens are designed to work with Apple's Repair Assistant without requiring technicians to transplant the original display IC or manually program True Tone data. On supported models, the replacement can complete the diagnostic process without triggering the usual "Unknown Part" warning, while features such as True Tone remain available without the traditional chip-transfer procedure. REWA markets this as a major step forward for aftermarket screen repair because it removes one of the most difficult and time-consuming parts of display replacement. 

Which Part Should You Actually Buy?

The right tier depends on the device, the use case, and who is doing the repair. These are the scenarios that matter in practice.

Frequently Asked Questions

Will a third-party iPhone battery show an Unknown Part message?

It can, but not every third-party battery behaves the same way. Apple says an iPhone may show Unknown when a replacement battery is nongenuine, cannot be verified, has been modified, or has not been properly linked to the device after repair. Some newer diagnostic-compatible aftermarket batteries, including products sold by REWA, are designed to complete Apple's Repair Assistant process.

Is a used-pull iPhone battery safe to install?

A used-pull battery can be a reasonable replacement if it is genuine, undamaged, properly tested, and still has sufficient capacity, but being an original Apple part does not make it equivalent to a new battery. On supported models, particularly iPhone 15 and later with iOS 18 or later, Apple allows a genuine battery previously installed in another iPhone of the same model to be reused and identifies it as Used in Parts and Service History. Its previous usage does not disappear: battery capacity, cycle count, and first-use history reflect the battery's actual life. So a battery sold at 90% health has already lost roughly 10% of its original maximum capacity. When buying a used-pull battery, check its health, cycle count, physical condition, testing history, and supplier warranty, and avoid batteries showing swelling, damage, or other signs of deterioration. 

Do third-party iPhone screens keep True Tone?

Some aftermarket iPhone screens can retain or restore True Tone, but it depends on the screen, repair method, iPhone model, and iOS version. Apple warns that True Tone may not work correctly with a nongenuine display because replacement displays may not have the same calibration and integration as an original Apple screen. Traditional aftermarket repair methods can involve transferring or programming display-related data, while newer diagnostic-compatible screens are designed to simplify the process. For example, REWA currently sells diagnostic-compatible screens that it says can complete Repair Assistant without an original display IC transplant, and some models do not require a separate True Tone restoration procedure. It is therefore inaccurate to say that every LCD or In-cell screen is physically incapable of supporting True Tone; compatibility should be checked for the exact replacement screen and iPhone model.

What is the difference between Soft OLED and Hard OLED iPhone screens?

The main difference between Soft OLED and Hard OLED is the substrate underneath the OLED panel. Soft OLED uses a flexible polyimide-based substrate, while Hard OLED uses a rigid glass substrate. Both are self-emitting OLED technologies, so both can produce deep blacks and high contrast without an LCD backlight. The flexible construction of Soft OLED makes it more tolerant of bending, frame flex, and installation stress, while rigid Hard OLED is generally more sensitive to uneven pressure or housing deformation and is commonly positioned as the more affordable aftermarket option. However, Soft OLED does not automatically guarantee better brightness, color accuracy, touch response, or overall quality a well-made Hard OLED can outperform a poor-quality Soft OLED, so the individual screen specification and supplier quality still matter.

The Summary in Three Sentences

For most people repairing a current flagship iPhone, Tier 3 Premium diagnostic-compatible parts from REWA or REPART hit the sweet spot: near-OEM display and battery performance, no iOS warnings, certified, and under warranty at a fraction of Apple's service price. Tier 1 Original parts are worth the premium only if you have AppleCare+, need enterprise compliance, or are preparing a device for resale at OEM condition. Tier 4 Budget aftermarket is acceptable only for low-value devices where function matters more than features expect degraded brightness, possible ghost touch, and persistent iOS notifications.

The key difference between soft OLED and hard OLED is the substrate: soft OLED uses a flexible polyimide base, while hard OLED uses rigid glass. Both are self-emitting panels that produce deep blacks and high contrast but soft OLED tolerates frame flex better and is the standard premium aftermarket tier, while hard OLED delivers similar image quality at a lower price.

Beyond substrate material, choosing the right replacement requires checking brightness, touch response, refresh rate, bezel fit, cover glass, and calibration. The construction label is a starting point, not a complete quality rating.

There is no doubt that Apple is the most innovative tech company in the world. Each year, they release new iPhones that are not only technologically advanced but also user-friendly and stylish. Many loyal Apple customers constantly look forward to getting their hands on the latest iPhone. Apple's success can never quite be replicated by other companies even when they release similar products.

Conclusion: 

iPhone 14 Pro is equipped with some amazing and innovative features this year, including a dynamic island, always-on display, a 48MB camera, etc. There isn't much good news as a repair shop when it comes to repairing the iPhone 14 Pro. The display still needs to be replaced, which is risky. There is also a possibility that the glass could be broken.

Some repair shops and distributors, due to the lack of professional purchasing guidance, fail to monitor storage temperature and humidity after purchasing batteries and cells in bulk, and also fail to charge the batteries in time. These wrong storage methods may result in battery failure after being stored for more than 3 months, such as poor voltage, battery bulging, etc., which will cause unnecessary losses.

Today, REWA shares battery storage and precautions, along with ways to recharge them, to help you store batteries and cells correctly, thereby save operating costs.

Why Should Batteries Be Stored Properly?

Lithium batteries are commonly used in phones, tablets, and other electronic devices. There are strict requirements for the storage of lithium batteries in terms of temperature and humidity. In terms of battery charging and discharging, temperature has the greatest influence among all environmental factors.

Lithium batteries' electrochemical reactions are related to ambient temperature. Firstly, if the temperature is too low, the battery will lock and there will be no voltage output. Battery lock means that when battery power drops to an extremely low state, the battery will automatically lock to protect battery health and user safety. Secondly, excessive temperatures will accelerate the battery's self-discharge rate, which is not conducive to long-term storage.

Additionally, lithium batteries cannot be left in a low-power state for an extended period of time, which will result in a reduction in battery life, and it is irreversible. For this reason, it is necessary to maintain the battery's performance by checking its voltage every three months as well as performing charge and discharge cycles if necessary.

How to Store Batteries Correctly?

If distributors or repair shops purchase batteries and cells in bulk, we recommend that they build a dedicated warehouse for storing batteries and cells in the following manner:

How to Recharge Batteries and Cells?

To maintain battery performance, REWA recommends testing battery voltage every 3 months. If the voltage is too low, the battery needs recharge.

Recharge Steps:

1. Use Multimeter to check batteries' voltage.

2. Use Battery Charge Activation Board and DC Power Supply to recharge batteries.

Guidelines:

1. Please store batteries according to the supplier's product instructions to ensure a safe voltage level. Different batteries may have different standard voltage levels.

2. When the battery voltage drops below the safe threshold, it is imperative to recharge it promptly and safely.

3. Note that deeply discharged batteries subjected to high-current charging may overheat, swelling, or damage. Therefore, for safe recharging, it is recommended to combine trickle charging with regular charging.

Please be aware that recharge operations require expertise. If needed, please contact REWA for customized recharge solutions. REWA provides both individual and bulk recharge solutions for batteries and battery cells.

Summary

The batteries and cells used in electronic devices, including mobile phones, tablets, smart watches, etc., are consumables with a limited lifespan. They can usually be charged and discharged 300-500 times. Thus, mastering the optimal storage method is equivalent to extending the battery's life and ensuring that your investment will yield a greater return.

Attempting to correct the Unknown Part warning issue on your own is not advisable, as it can potentially damage your device further. Instead, you should seek the help of a professional or an authorized repair shop.

What parts of the iPhone are most likely to cause the 'Unknown Part' warning message?

The parts of the iPhone that are most likely to cause the 'Unknown Part' warning message are the battery, screen, and camera modules. These components are functionally essential, and if they are not original or are not working correctly, they can cause the warning message to appear.

When to update your iPhone's software to prevent the 'Unknown Part' warning

It is suggested that you update your iPhone's software to the latest iOS version regularly, as new software updates usually fix bug issues, which might prevent the 'Unknown Part' warning from appearing on your iPhone camera.

What are some signs that the 'Unknown Part' warning indicates a more serious issue?

Suppose you experience other issues with your iPhone, such as a crashing app or an unresponsive screen. In that case, it may indicate that the 'Unknown Part' notification is related to a more serious issue. In such cases, it is recommended that you visit the Apple Store or seek professional help to diagnose and fix the issue.

How can I know if my iPhone is still covered by warranty?

You can check if your iPhone is still covered by warranty by going to the Apple website, clicking on 'Check Coverage,' and entering your device's serial number. The website will indicate if your device is still covered by warranty or not.

What to expect when taking your iPhone to the Apple Store or professional repair service

When you take your iPhone to the Apple Store or professional repair service, you can expect a thorough inspection of your device to diagnose the cause of the 'Unknown Part' warning. If the matter is related to a replaceable part, they will replace it with an original OEM part. The replacement cost will depend on whether your device is still covered by warranty or not.

Are you facing battery issues with your iPhone 12 Mini? Does your phone's battery life seem to be significantly shorter than when you first bought it? If so, it may be time to replace the battery. In this article, we will provide a step-by-step guide to replacing the battery in your iPhone 12 Mini. We will also introduce an innovative method that uses REFOX pre-programmed battery tag-on flex cable to make the process more efficient and convenient.

Why Replace Your iPhone Battery?

iPhone batteries are designed to retain 80% of their capacity for up to 500 charge cycles, which typically lasts for around 18-24 months for most users. However, as time passes, the battery in your phone may degrade, causing it to lose its ability to hold a charge. This can lead to shorter battery life and slower performance.

Replacing the battery in your iPhone can help to restore its performance and extend its lifespan. With a new battery, your phone will be able to hold a charge for longer and perform better.

Tools to Follow this Guide

It is important to have the right tools on hand when following a guide for repairing an iPhone battery or display. We have used a number of tools and repair parts in this guide to make our work more efficient and time-saving. The following is a list of the resources we used.

How to Replace iPhone Battery

It can be complicated to replace the battery in an iPhone 12 Mini. The good news is that with the right tools and an appropriate guide, anyone can replace an iPhone battery successfully. In addition, we used innovative methods and advanced tools in this guide in order to increase success rates. Please find below a step-by-step guide that will assist you:

Step 1: Remove the Battery

The first step in this guide is to separate the old battery from the iPhone 12 Mini. In order to accomplish this, we used the REFOX RS52 Cell Phone Screen Holder. As soon as the battery has been removed, it is important to peel off the protective tape and remove the bracket. 

Step 2: Remove the Battery BMS Board

The next step is to remove the battery BMS board.  To separate the BMS board, remove the protective tape carefully, remove the bracket, and use ceramic scissors to disconnect the anode and cathode. 

Step 3: Gringding And Soldering

Now you need to use a grinding pen to grind the solder point. Put the battery cell into the welding clamp fixture, and settle the cathode lead and anode lead under the BMS board. Be sure to align the anode and cathode leads respectively. After aligning the battery leads, solder them with the spot welder. After soldering the leads, fold them well and put them on the protection bracket. Then, wrap another layer of protection tape around the outside. Connect the tag-on flex to the battery and fold it to the right position as shown below. 

Step 4: Install the New Battery

Install the new battery back into your iPhone 12 Mini and turn it on.

Step 5: Check Battery Health

Click "Settings>Battery>Battery Health & Charging" and then check the battery condition. You should see that the maximum capacity is 100%.

Note: In order to boot up, you must connect the power cable or use the same type of battery

The New Method

In the past, it was necessary to operate through a programmer, battery detection modules, and tag-on flex to restore battery health and cycle time. However, with the new REFOX pre-programmed battery tag-on flex, the process has become more efficient and convenient.

The new method for battery data repair with iPhone 12 Mini battery cell replacement is similar to the previous method. The main purpose is to transplant the original Battery BMS board to solve the pop-up message, which allows the phone to detect the same battery code as the original after battery replacement.

After connecting the tag-on flex, you can reboot directly with the REFOX pre-programmed battery tag-on flex. You no longer need to connect the power cable or use the same type of battery to boot up.

With the introduction of the iPhone X in 2017, Apple Inc. introduced the Face ID feature. This feature improved the security of the Apple iPhone by almost 20 times compared to Touch ID while also providing additional convenience for the user. Since then, Apple has released several models of iPhones and iPads that come with the Face ID feature. However, it can be troublesome when Face ID is not working, causing inconvenience.

There are some traditional methods for fixing Face ID issues that involve disassembling the phone, welding, and aligning the device, which is time-consuming and labor-intensive. To solve this problem, REWA Tech introduced the latest and innovative REFOX RP30 multi-functional programmer. The RP30 can not only solve iPhones with Face ID issues, but it can also restore battery health and the true tone function of iPhones. It is our belief that by mastering the use of this device and technique, one will be able to greatly increase the efficiency of iPhone repairs.

How to Fix iPhone Face ID

REWA Tech understands the complexity of the Face ID repair or solution for iPhones, which is why we have designed a very simple solution for you to use. The only thing you need to do is to follow a few simple steps in order to resolve the issue.

Step 1. Preliminary judgment

The first thing we need to confirm is whether the failure of Face ID was caused by the dot fusion projector or not. So we turn on the phone to check Face ID. The screen shows that there is a problem detected with the TrueDepth camera. Face ID has been disabled. Then we dial the number to see if the proximity sensor and flood illuminator work properly. While focusing, the camera shows move farther away when set to portrait mode. Therefore, we can make a preliminary judgment that the issue of Face ID failure is caused by the dot fusion projector.

Step 2. Testing

After judgment, place the phone screen face down on top of the heating pad to heat it. We choose to use a screen opener to take the screen off and remove the battery and Face ID.

Next, put the battery and screen back into the phone and connect the phone to the computer. Then link the Face ID to the RP30 Projector for testing. The results show that the dot projector was fused. So we can use the latest solution to repair it.

Step 3. Fixing

Back up the data on the dot projector and connect the programmer to the high-voltage power cable.

Click activate and wait for the activation process to be completed. After the activation process, snap the dot projector cable onto the programmer and then write in the data that has been previously backed up. Then remove the dot project cable and snap the Face ID.

Be sure to pay attention to the folding process. If you have doubts about this, you can check our video or contact us for further discussion.

Step 4. Check

Connect the Face ID to the programmer again for the test. The test result is normal. Put Face ID back on the phone and install the battery and screen. Turn the phone on to test. Face ID can be set normally and unlocked successfully.

Above is the latest Face ID repair solution shared. Since this is a very simple and easy-to-follow solution that requires no soldering, level 2 technicians can now easily correct complex Face ID problems.

To Summarize

Fixing Face ID issues on an iPhone used to be a complicated process that required disassembling the phone and performing complex operations. However, with the introduction of the RP30 multi-functional programmer, level 2 technicians can now easily fix complex Face ID problems without soldering or complicated operations. This not only saves time but also reduces labor costs, making it an excellent choice for cell phone repair shops looking to improve their efficiency and customer satisfaction.

The no-soldering solution for fixing Face ID represents a significant advancement in the field of phone repairs. The step-by-step process for using the RP30 programmer is easy to follow, and the results are impressive.
