The iPhone is one of the best mobile devices out there, but it has to be said that the battery is one of the weaker parts of the iPhone. A new iPhone can be charged once a day for normal use. But as the iPhone's battery ages, it need to charged two or three times a day or more. This is a bad experience, and you may always worry that your phone is running out of battery. The iPhone has a battery health on the settings page to show how well your iPhone's battery is being used. When the maximum capacity data is lower than 80%. It's time to replace your phone's battery.

From ios 13.2 and after iphone XS, iPhone pop-up important battery message if we replace a new battery. This warning message make a lot of advanced users annoying. And the battery health page, the maximum capacity cannot be updated to 100%. How to solve this problem?

  • Step 9: Solder the BMS board to the new battery cell.

The new battery cell with the old battery board(BMS), so you get a combined battery that won't pop up after you install it back into the iPhone.

The battery health, and the maximum capacity data is updated to 100%.

After installing a new battery, the iPhone's battery health data cannot be restored to 100%, even if you transplant the principle battery motherboard. These data are recorded on the chip on the battery motherboard. To use programmer tools to modify the data. Different models use different methods.

For A11 cpu and below iphone models: iPhone X / iPhone 8 series / iPhone 7 series / iPhone 6s series / iPhone 6 series / iPhone 5 series / iPhone se etc.

There will be no pop-up messages and battery health problem on these models, and you can replace third-party batteries with confidence.

For A12 CPU iPhone models: iPhone XS Max / iPhone XS / iPhone XR.

These models of iPhone, after transplanting the battery motherboard to the battery cell, get a synthetic battery. Then use programmer tools for data updates. There are many of these programmer tools, for example: W28 Pro, JCID V1s, and QIANLI iCopy Plus

  • Step 1: Connect the battery to the Programmer.
  • Step 2: Use Qianli datamodification software.
  • Step 3: Click Reading, battery data on the BMS board can be seen.
  • Step 4: Recalibrate the cycle times and battery efficiency.
  • Step 5: Click Write-in

For A13 CPU and above iPhone models: iPhone 11 Series / iPhone 12 Series / iPhone 13 Series.

these iPhone is encrypted and cannot be accessed. That is to say, even if you replace with the original battery cell, the battery data sitll can't be read. Worse still, you can't correct the battery health and cycle count. The only solution available on the market is to use an external cable to connect to the battery cable. They call Teg-on flex

Step1: Prepare a battery transplanted with the original (old) battery motherboard.

Step2: Prepare a tag-on flex for your phone model.

Step3: Connect the tag-on flex to the battery cable, but pay attention to the positive and negative directions.

Step4: Bend the battery and tag-on flex to allow the battery to fit on the phone

Step5: Connect the tag-on flex to the potential programmer, paying attention to the direction of the connection.

Step6: Connect the potential programmer to the computer, open the Qianli software, and modify the data.

Step7: Install a non-native battery to your phone, start up, pop-up important battery message.

Step8: Shut down and reinstall the modified battery.

Notice:

1. When connecting the tag-on flex and the battery, you need to pay attention to the direction of the positive and negative poles, otherwise the battery will be damaged due to short circuit.

2. When the tag-on flex is connected to the programmer tool, you need to pay attention to the direction of the positive and negative poles, otherwise the battery will be damaged due to short circuit.

3. Before installing the battery with modified data, don't forget to install a non-native battery to the phone to reset the phone's battery data.

This seems to reset the battery health data to 100%, but I have to say, this solution fools the iPhone and us, because when you remove the tag-on flex, it shows that the battery health data does not change. The data we modified is actually written into the tag-on flex chip. So if you don't care about the issue of iPhone battery health data, you can ignore this process.

In addition, this solution is more happened in the used mobile phone market. In fact, the battery health data of many mobile phones is very low. The merchant only needs to connect the tag-on flex to the battery and modify the data. In order not to arouse the suspicion of customers, crafty merchants often modify the maximum capacity of battery health to about 98%, and consumers are completely unaware of all this.

Apple spares no effort to encrypt iPhone parts, which greatly increases the difficulty of repairing our phones. Although there will be new solutions to slove these problems, but it's not perfect. Apple strips consumers of repair rights, even though we paid for them. It is undeniable that Apple invented the iPhone and subverted the smartphone industry, but should Apple also care about the needs of consumers? Not everyone can easily replace a new iPhone, although Apple wants consumers to buy a new iPhone rather than repair it.
