🔋 Is Your iPhone 12 Battery Letting You Down?
The iPhone 12 and 12 Pro launched in 2020. With over four years of daily charging behind them, many are now well below the 80% health threshold Apple considers serviceable. The phone itself is still capable — the battery is the only reason it feels like a downgrade. Replacing the battery is significantly cheaper than a new phone and restores the experience to day one.
📉 Health Below 80%
Settings shows "Service Recommended". iOS may throttle performance to compensate for a weak cell.
⚡ Sudden Shutdowns
Phone dies at 20–30% charge. The displayed percentage is no longer accurate of actual remaining capacity.
🔥 Gets Hot Charging
Rising internal resistance in a degraded cell generates more heat during every charge cycle.
🐢 Performance Throttled
iOS limits CPU speed to protect a weak battery. Apps stutter. The camera is slow. Games drop frames.
🔌 Charging Twice A Day
A phone that used to comfortably last all day now struggles past afternoon. Less capacity equals fewer hours.
✅ The Fix: New Battery
A 0-cycle Greencell 2815mAh battery restores full capacity and iOS health reporting shows 100% from day one.
🔬 Diagnosable — iOS Battery Health Works Correctly
The Greencell Diagnosable battery communicates directly with iOS — no extra tools or programming required.
🔴 Standard Aftermarket Battery
A standard third-party battery shows "Service — Battery health reporting is not supported for this iPhone" in Settings permanently. iOS cannot communicate with it. No health percentage. No accurate charge data.
🟣 Greencell Diagnosable BMS
The Greencell battery includes a compatible Battery Management System chip. iOS reads genuine capacity, voltage, and cycle data automatically on first boot after installation. Nothing extra needed.
🟢 The Result After Install
Settings → Battery → Battery Health shows 100%. No service warnings. No "not supported" messages. iOS calibration works normally. The battery behaves as a genuine replacement from first charge.
Note: If other non-genuine parts such as a screen or camera module are already installed, Apple's Repair Assistant diagnostic flow may not fully complete. This does not affect battery function or iOS health reporting — the battery itself works correctly regardless.
🏭 Why Greencell? — Brand, Quality & Certifications
Greencell is a reputable battery brand distributed through professional mobile repair channels. Every Greencell battery is individually tested before dispatch. Capacity, voltage, and watt-hour ratings are verified and stated accurately — unlike budget cells that ship with inflated unverified specs. The 12-month warranty is possible only because Greencell has confidence in what they produce.
✅ CE Certified
Verified compliance with European safety and electromagnetic compatibility standards — not a self-applied sticker.
✅ ROHS Certified
Free from lead, mercury, cadmium, and other restricted hazardous substances. Safe to handle and dispose of through e-waste.
🔒 Multi-Layer Safety
Overcharge protection, overheat cutoff, short circuit protection, and temperature control all built into the battery management circuit.
🧪 Individually Tested
Every unit is tested before leaving the facility. Not batch-sampled — each battery is verified for capacity, charge acceptance, and safety circuit function.
⚠️ Installation Notes — iPhone 12 / 12 Pro Battery Replacement
The iPhone 12 and 12 Pro open from the front display. The display assembly must be carefully lifted to access the battery. These models carry an IP68 waterproof rating — the adhesive seal around the display must be replaced correctly during reassembly to maintain water resistance. Do not rush the seal reapplication. Work in a clean, dust-free area.
Tools Needed (DIY)
Pentalobe P2 driver, Phillips 00, suction handle, opening picks, spudger. Heat gun or hair dryer to soften display adhesive. Display adhesive tape for resealing.
Adhesive Strips Included
Fresh pull-tab adhesive strips are included in the box. Remove the old battery cleanly by slowly pulling each tab. Apply the new strips before seating the Greencell battery.
In-Store Installation Available
Bring the iPhone and part to Shop 3A, 152 Woogaroo St, Forest Lake QLD 4078. Our technicians handle iPhone 12 and 12 Pro battery replacements in store, including display resealing.
📱 Compatibility — iPhone 12 and 12 Pro
The iPhone 12 and iPhone 12 Pro share the same battery. One Greencell unit fits both models. Confirm your exact model before ordering.

Frequently Asked Questions
What does "Diagnosable" mean for this iPhone 12 battery?+
Diagnosable means the battery includes a compatible Battery Management System chip that communicates directly with iOS. When you install the Greencell Diagnosable battery and power on the iPhone, iOS reads the battery data automatically — no extra tools, no programming, no external device needed. Settings → Battery → Battery Health shows 100% from the first charge cycle. Standard aftermarket batteries without this chip show "Service — Battery health reporting is not supported for this iPhone" permanently. The Greencell Diagnosable battery eliminates that warning from day one.
Will iOS battery health show 100% after installing this?+
Yes. The Greencell Diagnosable battery is specifically designed to display 100% battery health in Settings → Battery → Battery Health after installation. This is a 0-cycle battery — it has never been charged before dispatch. iOS reads the Greencell battery data and confirms full capacity with no warnings. Allow the iPhone to complete one full charge cycle after fitting the battery for the reading to fully stabilise. The "Service Recommended" and "not supported" messages that appear with standard third-party batteries do not appear with this Greencell unit.
Does this battery fit the iPhone 12 Mini or 12 Pro Max?+
No. This battery fits the standard iPhone 12 (6.1-inch) and the iPhone 12 Pro (6.1-inch) only. These two models happen to share the same battery, so one Greencell unit covers both. The iPhone 12 Mini uses a smaller battery with different dimensions. The iPhone 12 Pro Max uses a significantly larger battery. Fitting a mismatched battery is a safety hazard and will not function correctly. Check your model in Settings → General → About → Model Number. Australian iPhone 12 is A2403. Australian iPhone 12 Pro is A2407.
Are the adhesive strips included in the box?+
Yes. Pull-tab adhesive strips sized for the iPhone 12 / 12 Pro battery bay are included in the box. The existing adhesive strips stretch and release when you pull the tabs slowly during removal. The Greencell pack includes fresh replacement strips to seat the new battery securely. You do not need to purchase a separate adhesive kit for the battery. Note that the display adhesive seal around the perimeter of the screen is a separate item — if you want to restore the IP68 waterproof rating fully, you should also apply a display seal strip during reassembly.
How hard is the iPhone 12 battery replacement as a DIY job?+
The iPhone 12 opens from the front display, which requires more care than the iPhone 14's rear-opening design. You need to heat the display adhesive, suction it open carefully, and disconnect the screen before reaching the battery. The battery itself pulls out cleanly using the pull-tab strips. The main challenge for maintaining IP68 water resistance is correctly resealing the display adhesive on reassembly. For confident home repairers with proper tools and iFixit guides, it is a manageable intermediate repair. For anyone not comfortable with display removal, bringing the phone to our Forest Lake store is the better option.
Is this a genuine Apple battery?+
No. This is a Greencell branded aftermarket replacement battery, not an Apple OEM part. Apple sells genuine batteries through Apple Stores and authorised service providers at a higher cost. The Greencell battery matches the iPhone 12 / 12 Pro original specification of 2815mAh at 3.83V, carries CE and ROHS certifications, includes Diagnosable iOS compatibility, and is backed by a 12-month warranty. For most repair shops and DIY repairers, it is the practical, cost-effective choice that delivers full battery health reporting without the Apple service premium.
What safety protections does the Greencell battery include?+
The Greencell iPhone 12 / 12 Pro battery includes four built-in protection circuits: overcharge protection cuts the charge current when the battery reaches maximum voltage; overheat protection shuts off charging if temperature exceeds safe thresholds; short circuit protection disconnects the battery instantly if a short is detected; and temperature control monitors the cell continuously during use. These circuits are part of the Battery Management System chip. CE and ROHS certifications confirm the battery meets verified safety and materials standards. Each unit is individually tested before dispatch.
What happens with Apple's Repair Assistant if I have non-genuine parts installed?+
Apple's Repair Assistant is a diagnostic tool in newer iOS versions that can verify parts after a repair. If other non-genuine components such as a display, camera module, or Face ID sensor are already installed in the iPhone, the Repair Assistant diagnostic flow may not fully complete. This does not affect whether the Greencell battery itself works correctly — the battery installs, charges, and reports iOS health normally regardless. The Repair Assistant limitation is specific to Apple's multi-part diagnostic sequence and is not a limitation of the Greencell battery. If you have questions about your specific situation, call us on 0480 039 913 before ordering.
What does the 12-month warranty cover?+
The 12-month Greencell warranty covers manufacturing defects and battery failure under normal operating conditions after correct installation. Covered issues include failure to charge, sudden capacity loss not caused by external damage, and safety circuit failures. The warranty does not cover physical damage from incorrect installation, puncture, water ingress after fitting, or capacity degradation from normal charge cycling over time. Australian Consumer Law rights apply to all purchases from JPC Mobile independently of this warranty. Warranty claims are handled at Shop 3A, 152 Woogaroo St, Forest Lake QLD 4078, or by calling 0480 039 913.
