Standard or Cell Only: which to choose
Both replace a worn iPhone SE 3 battery. The difference is what happens to the battery IC, the small board that tells iOS which battery is fitted, and that decides what the phone shows afterwards.
| Feature | Standard (this part) | Cell Only |
|---|
| What you get | Complete battery with its own new IC, no adhesive | Bare cell, no IC board, adhesive included |
| Your original battery IC | Replaced | Soldered onto the new cell |
| Parts and Service History | “Unknown” | Reads as your original battery |
| Battery Health | Shows a percentage from iOS 18 | Comes from the data stored on your original IC |
| Skill needed | A standard battery swap | Micro-soldering |
| Best for | A straightforward, lower-cost swap | Keeping the phone reading the battery it already had |
Choose Standard for a straightforward swap with no soldering, when an “Unknown” label in Settings does not matter. If the phone should keep reading its original battery, the Cell Only version keeps the original IC but needs micro-soldering.
About the iPhone SE 3 replacement battery
This is a complete replacement battery for the iPhone SE 3: a new lithium-ion polymer cell with its own IC board and connector, supplied without adhesive. It fits as a straight swap, with no soldering.
The iPhone SE 3, the third-generation iPhone SE, was released in 2022. At 2018 mAh it is a compact battery, sized for the 4.7-inch body the iPhone SE 3 shares with the iPhone 8. The iPhone SE 3 is opened from the screen side, so the display comes off before the battery can be reached.
The original iPhone SE 3 battery carries model number A2819 on its label. Checking it against the old battery before you start confirms you have the right replacement.

Compatible iPhone SE 3 model numbers

It does not fit other iPhone models: the iPhone SE 2 uses a 1821 mAh battery. Check the model number in Settings > General > About, or use Apple’s guide to identifying your iPhone.
How to fit the iPhone SE 3 replacement battery
For technicians and experienced repairers. Work on an ESD-safe bench, and never lever against a lithium battery: a punctured cell can catch fire.
- Prepare the bench. Precision screwdrivers, a heat mat or heat gun, a suction handle, plastic picks and fine tweezers.
- Open the phone from the screen. Heat and lift the display, then unplug the battery connector before touching anything else.
- Remove the old battery. Pull the adhesive tabs out slowly at a low angle, then lift the battery out without bending or puncturing it.
- Prepare the frame. Apply fresh battery adhesive strips, which are not supplied, where the old battery sat.
- Fit the new battery. Line it up, press it into place, and reconnect it.
- Test and close. Check the phone boots and charges, then reseal it with fresh display adhesive.
After the swap, Parts and Service History (Settings > General > About) lists the battery as “Unknown”, because iOS cannot verify an aftermarket battery. Battery Health still shows a percentage, 100% on a new battery, though Apple notes that health readings for a battery it cannot verify might not be accurate. The phone charges and runs normally. Apple explains both in its guides to Parts and Service History and genuine iPhone batteries.

Frequently asked questions
How is the Standard battery different from Cell Only?
Standard is a complete battery with its own new IC, fitted as a straight swap. Cell Only is a bare cell that keeps the phone’s original IC but needs soldering.
Will iOS show the battery as Unknown?
Yes. Parts and Service History lists it as “Unknown”, because iOS cannot verify an aftermarket battery. The phone charges and runs normally.
What will Battery Health show?
From iOS 18, a percentage: 100% on a new battery. Apple notes that health readings for a battery it cannot verify might not be accurate.
Do I need to solder?
No. It is a complete battery, so it swaps in without soldering. Soldering is only needed for the Cell Only version.
Is the iPhone SE 3 battery the same as the iPhone SE 2 battery?
No. The iPhone SE 3 takes a 2018 mAh battery and the iPhone SE 2 a 1821 mAh battery, each shaped for its own phone, so the two are not interchangeable.
Is battery adhesive included?
No. The battery comes without adhesive, so fit fresh battery adhesive strips when you install it.
Which iPhone SE 3 models does it fit?
Model numbers A2595, A2782, A2783, A2784 or A2785. Check yours in Settings, then General, then About.
Is this an Apple original battery?
No. It is an aftermarket battery, not an Apple part.
What warranty comes with it?
6 months against manufacturing defects. Physical damage, punctures and damage caused while fitting are not covered.
