Apple has encrypted the battery of iPhone XS and models above. Once you replace the battery, you will get the “Important Battery Message” and “Service” message. To make matters worse, the cycle count of the new battery will show the cycle count of the original battery.
-
Especially the battery data of iPhone 11 series and iPhone 12 series still can’t be accessed. It has been verified by technicians that the “Important Battery Message” will show up after you put in an aftermarket battery or a genuine Apple battery.
-
You can only avoid the problem by letting Apple Stores or Apple Authorized Service Providers replace your battery.
-
-
-
To solve the problem, the latest solution has been verified. Today we will share solutions concerning iPhone XS series, iPhone 11 series and iPhone 12 series.
-
First of all, we will introduce the structure of the battery. The battery can be roughly divided into two parts – BMS board and battery cell. The battery management system board mainly serves as a protection board but also saves battery data. The battery cell is where the power is stored.
-
-
-
Taking iPhone XS for example, we need to prepare a battery data corrector and a new battery cell that can be an original one or an aftermarket one. Disassemble the phone and remove the battery.
-
Then we need to Spot Weld the BMS board of the original battery to the new battery cell. Remove the protective tape on the BMS board. Please do not break the flex cable.
-
Disconnect the cathode and anode of the battery with a pair of scissors.
-
-
-
-
Please be noted that you can only turn on the phone by a power cable. The above step takes advantage of bugs in iOS and is a very important step. Then we install the new battery. Go to “Settings” to view the battery health information. The maximum capacity is 100% and there is no “Important Battery Message”.
-
Different from iPhone XS series, the battery data of iPhone 11 series and iPhone 12 series is encrypted and cannot be accessed. That is to say, even if you replace with the original battery cell, the battery data still can’t be read. Worse still, you can’t correct the battery health and cycle count.
-
Recently, we have got the latest battery data corrector on the market. Through verification, the corrector can effectively remove the “Important Battery Message” of iPhone 11 series and iPhone 12 series. Next, we will share the operation process in detail by an iPhone 11 Pro.
-
Remove the BMS board of the original battery. Solder the BMS board to the new battery cell.
-
-
-
Then connect the battery to the programmer. Click reading. Recalibrate the cycle times and battery efficiency.
-
Connect the power cable to turn on the phone. “Important Battery Message” is displayed.
-
Then we install the new battery. Go to “Settings” to view the battery health information. The maximum capacity is 100% and there is no “Important Battery Message”.

Hey i have an iPhone 13 and it's got important Battery message for no Reason, it's never get a battery replace beside it's never open before also it's only run 6 months, the only issue i think is happend is i used a another charging adapter that all, is this is an apple where if you used another charging adapter you got an battery error, then it's not a smartphone Company its a piece of trash, i would bever ever buy anything from this brand
"RIP apple"
I have iPhone 13 mini and just like you, mine suddenly got important battery message despite never got it replaced nor repaired. Furthermore, my phone was acting weird, it won't charge and the battery percentage stayed at whatever it is although being used for hours.
Because it's my main phone, I can't have it to official repair store (because then my phone needs to stay for at least a week there), then I went to local repair store nearby and they said for whatever reason my original battery flex or its BMS board is broken.
I replaced the battery right away. Now it works perfectly eventhough I have to see that important battery message everytime I go to setting.
