Due to the high price of Apple’s original batteries, many iPhone users are looking for alternative battery replacement options. When it comes to iPhone XS battery replacement, you may often hear the term “cell replacement”.If you have already started to wonder what battery replacement is, then it is very necessary for you to read this article!
1. What Is a Battery Cell?
To put it simply, replacing the battery cell is actually a type of battery replacement, just in a less common way.
An iPhone battery consists of two main parts:
-
Battery cell – responsible for storing power and determining how long your phone can last on a charge. In other words, the battery cell can be seen as the “core” of the battery.
-
Battery flex cable (with protection board) – responsible for recording charging cycles, battery health, and the unique serial number.
Starting from the iPhone Xs series, Apple has encrypted the battery protection cable. When replacing a non-original battery phone, when reading the information of the protection cable, it will find that the battery information is inconsistent with the original phone, and it will prompt an unknown component, and will not display the battery efficiency.
Battery cell replacement means swapping out the old cell for a new one while keeping the original flex cable intact. Starting with the iPhone XS series, Apple encrypted the flex cable data. If you replace the entire battery without the original chip, the system detects a mismatch, shows an “Important Battery Message”, and hides the battery health display.
2. Why Choose to Replace the Battery Cell?
On iPhone XS and later models (such as XR, 11, 12, 13), Apple’s battery encryption makes third-party replacements more complicated. Even swapping an original battery from another identical iPhone will trigger the “unable to verify this iPhone has a genuine battery” warning.
This encrypted battery information is stored on the battery protection cable. When replacing a battery cell, the original battery's protection cable is used, so the phone system still reads the old battery's information. The phone won't indicate a battery replacement, and the "unknown component" message won't appear, allowing the battery health indicator to display normally.
3. What Is the “Original Flex Cable + High-Capacity Cell” Solution?
-
Original flex cable: Retains the iPhone’s original data chip, so the phone continues to read the same information as before.
-
High-capacity cell: A premium replacement battery cell with a larger capacity than the original.
By combining these two, the replacement battery avoids detection as “non-genuine,” performs better, and offers a seamless user experience.
4. Key Advantages of This Solution
No Pop-Up Warnings
Since the original flex cable is reused, the system recognizes the replacement as the same battery. This prevents the “unable to verify this iPhone has a genuine battery” message and allows normal battery health display.
Battery Health Works Normally
Unlike standard third-party replacements, this method lets you check maximum capacity and peak performance directly in Settings, just like with an original Apple battery.
Longer Battery Life with High-Capacity Cell
The high-capacity cell not only restores performance but also offers greater capacity than the stock battery. In many cases, the new cell provides even longer usage time than the battery your iPhone had when it was brand new.
Nearly Invisible Replacement
Because the original Apple flex cable is retained, it’s almost impossible to tell the battery has been replaced without opening the device. This is especially valuable if you plan to sell or trade in your iPhone later.
5. Who Is This Solution For?
-
Users of iPhone X, XS, 8, 7, and other earlier models
-
Heavy users who require longer battery life and stronger endurance
-
iPhone owners who want to keep the original experience without seeing the “non-genuine battery” warning
-
Second-hand iPhone users who plan to sell or trade in their device and want to maintain its value
For users considering an iPhone XS battery replacement (and other earlier models), the original flex cable + high-capacity cell solution is one of the smartest choices. It combines Apple-level compatibility with the benefits of extended battery life, avoids frustrating pop-up warnings, and keeps the battery health feature fully functional.
If your iPhone battery no longer lasts as long as it should, this method can make your device feel brand new again—without the high cost of an official replacement.
