Fit, charge, done
- No “Unknown Part” or “Important Battery Message”.
- Battery Health shows normally in Settings.
- No chip work and no programming.
- 1-year replacement warranty.
Standard · Shows Unknown Part
Lowest price: same backup, shows “Unknown Part”
- Same capacity and the same day-long backup as any new battery.
- iPhone shows “Unknown Part” or “Important Battery Message” in Settings and hides the Battery Health %. Nothing else changes.
- To make it show as original, a technician must move the BMS (battery management system) chip strip from your old battery onto this one (soldering). If that is not done properly, it can damage the battery.
- 3-month replacement warranty, as long as the chip has not been moved and the battery shows no signs of tampering. No warranty once the chip is moved.
- Pick Standard if you care about battery backup, not the message.

Fit it yourself
You have Standard selected: fit it exactly as below. It works with full backup and shows “Unknown Part”. Moving the BMS chip from your old battery is optional, needs a technician with soldering tools, and ends the warranty.
Premium and Standard fit the same way: a straight swap, no programming. If you have opened a phone before, you can do it at home in about 45–60 min. If you would rather not, any local mobile repair shop will fit it for about ₹300–₹500. We don't offer fitting for iPhones.
Difficulty
Moderate
The battery is reached from the front: the screen lifts off first, then the battery comes out.
Tools you need
P2 PentalobeY000 Tri-pointPhillips #000Suction cup · picks · spudgerHair dryer
Steps
- Power off the iPhone and remove the two P2 pentalobe screws next to the charging port.
- Warm the bottom edge with a hair dryer for a minute. Lift the screen with a suction cup and slide a pick around the edge. Open it like a book; don't pull the cables.
- Remove the connector cover plate (Y000 tri-point and Phillips #000 screws). Disconnect the battery first, then the screen.
- Remove the parts covering the battery's pull-tabs (the bottom speaker or Taptic Engine, depending on the model), then pull the tabs slowly and flat. Don't pry or bend the old battery.
- Place the new battery (adhesive already on it), press it down, and connect the screen first and the battery last.
- Switch on and test before closing. Close the screen, refit the two bottom screws, and charge to 100% once.
Good to know: the screen seal is not included. Without a new seal the phone works normally but is less water-resistant than before. Damage caused while fitting is not covered by warranty.

Returns
No returns or refunds on batteries. Batteries are a safety item and can't be resold once they leave us. If your battery is faulty when it arrives, we replace it under warranty (see the Warranty tab).
Unboxing video needed
- Record one continuous video from the sealed parcel until the battery is out and inspected.
- Report any problem within 24 hours of delivery on WhatsApp with the video and photos.
Warranty
| Premium (Direct Swap) | 1 year replacement warranty by Sparesonly.in |
|---|---|
| Standard, fitted as it is (no chip change) | 3 months replacement warranty by Sparesonly.in, if the battery shows no signs of tampering |
| Standard, chip moved | No warranty. Moving the chip is soldering work on the battery that we can't check or control. |
Covered
- A manufacturing fault: the battery does not hold charge, does not power the phone, or Battery Health (Premium) reads abnormally low within the warranty period.
Not covered
- Swelling or bulging caused by heat, a faulty charger or physical pressure.
- Damage during fitting: a bent, torn or punctured battery, a damaged connector or flex, or a bent battery from prying.
- Physical damage, liquid damage, or cut or tampered cables or connectors.
- Normal wear: capacity slowly dropping with use and charge cycles.
- Standard: any battery where the BMS chip strip has been moved, or that shows signs of tampering.
To claim, message us on WhatsApp with your order number, the unboxing video and, for Premium, a Battery Health screenshot. We test the returned battery and replace it if it is faulty. For Standard, we also check the battery strip for signs of the chip being moved.
iPhone 12 battery: your questions
When should I replace my iPhone 12 battery?
When Maximum Capacity in Settings → Battery → Battery Health & Charging drops below 80%, or when the phone shuts down at 20–30%, drains fast or feels slow.
Will it fit my iPhone?
Only the iPhone 12 (6.1-inch, 2020): models A2172, A2402, A2403, A2404. It does not fit the iPhone 12 mini, iPhone 12 Pro Max, iPhone 13.
What is the difference between Premium and Standard?
Premium is a direct swap with no warning message, normal Battery Health and a 1-year warranty. Standard costs less and gives the same backup, but shows “Unknown Part”; it has a 3-month warranty as long as the chip is not moved.
Does Standard work without moving the chip?
Yes. Full backup and normal charging. It only shows “Unknown Part” or “Important Battery Message” and hides the Battery Health %.
Does moving the chip void the warranty?
Yes. The warranty ends as soon as the BMS chip strip is moved, because the soldering can damage the battery and we can't check that work.
Can I fit it myself?
Yes, if you are comfortable opening a phone. It takes about 45–60 min with the right tools (see Fit it yourself). Otherwise, a local repair shop will fit it for about ₹300–₹500.
Which tools do I need?
P2 Pentalobe, Y000 Tri-point, Phillips #000 screwdrivers, a suction cup, opening picks and a spudger. Tools are not included; you can add a kit on this page.
Does the battery come with adhesive?
Yes. The adhesive strips are already on the battery. The screen seal is not included.
Will my iPhone stay water-resistant?
Only if the screen is resealed with a new seal. Without one it works normally but resists water less than before.
How do I calibrate the new battery?
Use the phone normally until it reaches about 10%, then charge to 100% without interruption. Battery Health settles within a day or two.
Can I return the battery?
No. Batteries can't be returned or refunded. A faulty battery is replaced under warranty when reported with the unboxing video.
What does the warranty not cover?
Swelling from heat or bad chargers, damage while fitting, physical or liquid damage, tampered cables and normal capacity loss over time. For Standard, also any battery where the chip has been moved.
Do I get a GST invoice?
Yes, with every order. Businesses can claim input tax credit.
How fast will it reach me?
Chennai same day, rest of Tamil Nadu next working day, Kerala, Bengaluru and Hyderabad in 1–2 days, rest of India in 2–7 days.
