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.

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.

Programmer: Easy steps of replacing battery or display on the iPhone

Normally we replace the original iPhone screen or battery with the third-party one when it confronts a screen or battery problem. Overall, it's more cost-effective. 

But after replacing it with the new battery, the alert message from iPhone will pop up starting from the XS Series since the replacement is not the iPhone original. Not only this, the cycle of the battery shows different from the original one. Though it will not affect the battery's performance on iPhone. We need a multifunctional iPhone repair programmer to restore data in this condition as well as to repair the Face ID dot matrix. 

Now we use REFOX RP30 Multi-function Restore Programmer for iPhone as an operation reference.

In the first place, there are some steps for REFOX RP30 Multi-function Restore Programmer. It's unnecessary to use the external flex cable for the replacement of the iPhone XS/XS MAX/XR to remove the Important Battery Message. We just need to solder the original battery board to the new battery, then connect it to the repair programmer and recalibrate the data on it. That's done. 

But the battery since iPhone 11, we need an external flex cable except for the operation as above. After soldering the original battery board to the new battery, connect the flex cable with the motherboard ”Important Battery Message“ is displayed. Then we install the new battery. Go to "Setting" to view the battery health information. The maximum capacity is 100% and there is no“Important Battery Message”

It's time to put this RP30 Multifunctional repair programmer into your shopping cart. Good to improve your work efficiency!

If your phone battery is in a low health condition, like 80%, it's time to replace a new one. Here are some tips for display replacement. We will bring you a case iPhone X as a reference. All you need is a repair kit and a new battery. The repair kit should be included as below: tweezers, screwdrivers, pry piece, suction cup, heating pad, spudger, battery adhesive, and waterproof adhesive.

Firstly, please long press the phone to turn it off. Then you can use a pentagon screwdriver to unscrew the screws at the bottom of the phone. Please pay attention to putting the screws aside well. You can place the screen face down on the pad for about 2-3 minutes after the heating pad is up to the temperature of 70—80°c. And fix the suction cup at the bottom of the phone, lift the screen gently, and insert a pry piece underneath. Gradually move around the edge of the display, separating the screen along the gap. The display assembly is still connected to the iPhone by cables, so don't try to remove it completely. Again, please pay attention to the position of the cable to avoid damage. The angle should not be greater than 90 degrees to prevent breaking the flex cable. The process of removing the cover is done.

Next, use a Tri-wing screwdriver to unscrew the screws on the shielding cover of the cable connector. You can use a spudger slightly to extricate the battery and the connector between the screen and motherboard. Now, continue to follow instructions step by step. Detach the earpiece speaker flex cable, and remove the old display assembly.

Then, please use tweezers to clean up the battery adhesive. It's suggested to detach the Taptic Engine and loudspeaker better to remove the adhesive at the bottom of the battery. Again, use a Tri-wing screwdriver to unscrew the screws on the speaker flex cable and detach the shielding cover.
 
After taking out the loudspeaker and Taptic Engine, let's continuously remove the battery adhesive. Because the adhesive at the bottom of the battery has been for a long time, it's hard to remove it. We need to drop some alcohol to help clean up. Drop the alcohol around the edge of the battery, and leave it to penetrate and evaporate. Use tweezers to make it lose, take out the old battery, and continue to remove the rest adhesive. Please keep removing the waterproof adhesive around the frame. And replace the Taptic Engine and loudspeaker. Remember to tighten the screws and replace it with the new battery.
 

Tear off the film of the battery adhesive, and make its glue adhere to the battery. Press it slightly, and tear off the film. Please put on the new battery, and press it slightly. Use a spudger to disengage the battery connector. Reassemble the display cable, touch cable, and continuously.
 
Please turn it on. Check the health condition of the battery. 
It shows the maximum capacity of the battery now is 100%. Please turn it off. Tear off the waterproof adhesive. Make it adhere to the phone body. Press lightly with tweezers to make it adhesive. Tear off the film. Reassemble the display cable and touch cable. Reassemble the earpiece speaker flex cable, and connect the battery. Install the shielding cover, and tighten the screws. Take off the waterproof adhesive around the frame. Buckle the phone screen.

Please turn it on again. Let's do some battery tests. 
First is the wired charging test. Next is the wireless charging test. It's working. Both are working.

The above guidance is about the battery replacement process. If you have any problems or advice, please leave us a comment below. 
 

There are some myths around iPhone batteries and the genuine battery alert. Today we will walk you through these myths.

Is the size of aftermarket high-capacity batteries bigger?

Nowadays, the latest technology is used to produce batteries of old models, which increases the density of battery while keeping the original size.

Are genuine batteries more durable than aftermarket batteries?

They are almost the same. Our batteries are made of A quality cells with proven technology. Through rigorous tests, the cycle count of more than 80% of the batteries can exceed 600 while more than 60% surpass 800.

Will aftermarket batteries slow the phone?

No, it will not slow the phone unless you buy inferior ones and the output voltage is low.

For battery replacement of 2018 models and higher ones, “Important battery message” will pop up. If the battery cell (XS-13 Pro Max) is changed with original data unchanged, there is no“Important battery message”. To make the message disappear if the data is changed, models of XS -XR doesn't need a flex while a tag-on flex is required for 11-13 Pro Max. If you don’t have the skills for cell replacement, you can directly choose our batteries.

We have also published detailed videos on how to remove the genuine battery message alert. Please feel free to share your thoughts on iPhone battery.
