Guide overview

Before you begin

For iPhone XS and above, when a third-party battery or a genuine replacement battery is replaced by a third-party repair shop that isn't one of Apple's authorized partners, the battery health menu will show a warning about being ‘unable to verify this iPhone has a genuine iPhone battery’. How to remove the annoying message? Check out below and see how REWA LAB fixes the problem with a hardware solution.

Step 1

Why the important battery message appears

⌕

Why the message appears after battery replacement?
Chips used in batteries of iPhone XS and above feature an authentication module which stores information that can be used to pair the battery cell with the phone’s logic board.
To remove the Important Battery Message, we can transplant the battery management system of the original battery to the replacement battery.

Step 2

Remove Original BMS

⌕

Here we will use a new iPhone XS battery cell.
Tear off the insulation tape on the original battery management system. Then remove the protective cover. Remove the battery management system with Cutting Nipper afterwards.
Be careful during your operation. Do not tear the battery flex cable or damage the battery management system.

Step 3

Weld Original BMS

⌕

Now we need to weld the original BMS onto the new battery cell.
Cut off a part of the nickel sheet on the new battery cell. Then place the BMS in the right position. Do not confuse the anode with the cathode.
Continue to weld the BMS with the welding machine. Once done, apply the protective cover and insulation tape.

Step 4

Test

⌕

Activate the battery with the activation board. Then get the battery installed.
Connect the screen and then the battery. Power on and test. There is no important battery message this time.
