iPhone 16 Plus Replacement Battery

The iPhone 16 Plus replacement battery is a zero-cycle 4674 mAh aftermarket cell that matches the original Apple capacity, voltage, and watt-hour rating. Built around a Texas Instruments battery management IC and supplied as the cell only (no pre-installed adhesive, to match the iPhone 16 Plus’s powered debond install process), it restores a tired iPhone to all-day runtime. Supplied by GA Tech NZ from local stock with same-day weekday dispatch and a 6-month manufacturing-defect warranty.

  • Original-spec 4674 mAh / 18.11 Wh capacity for runtime that matches the factory cell.
  • Zero-cycle Li-ion chemistry with 3.875 V nominal and 4.5 V charging cutoff, identical to Apple’s reference design.
  • Cell ships without pre-installed adhesive; powered debond install requires fresh adhesive strips and a 9V or USB-C PD power source (sold separately).
  • iOS 18 and later display Battery Health percentage after install, with “Unverified” label in Parts & Service History.
  • NZ stock, same-day dispatch, 6-month warranty, plus in-house fitting available through GA Tech NZ.

More Info

The iPhone 16 Plus replacement battery is a high-quality 4674 mAh aftermarket cell engineered to restore your iPhone 16 Plus to original-spec runtime. In particular, capacity, voltage, watt-hours, and physical dimensions all match Apple’s reference design, so the battery drops into the existing chassis with no shimming, no fit issues, and no surprises at boot. In addition, NZ stock, professional-grade build, and a 6-month warranty round out the package.

Why choose this iPhone 16 Plus replacement battery?

This iPhone 16 Plus replacement battery brings four advantages that matter for a daily-driver repair: an original-spec 4674 mAh cell that restores factory-equivalent runtime, a Texas Instruments battery management IC for safe charging and discharge protection, an install workflow matched to the iPhone 16 Plus’s service profile, and full NZ logistics with same-day dispatch from local stock. The cell ships zero-cycle, which means it has not been charged or discharged before reaching you, so you get the full design lifespan from day one.

Product information:

  • First, this is an aftermarket replacement battery cell for the iPhone 16 Plus. Of course, GA Tech NZ holds no affiliation with Apple Inc., and this listing is not a genuine Apple battery replacement.
  • Additionally, the cell ships without pre-installed battery adhesive; replacement adhesive strips are sold separately. However, display adhesive (for resealing the screen) is sold separately.
  • Therefore, GA Tech NZ recommends professional installation to protect the flex cables and battery connector. In addition, GA Tech NZ offers in-house iPhone 16 Plus battery replacement.

iPhone 16 Plus replacement battery overview

First, this iPhone 16 Plus replacement battery fits Apple iPhone 16 Plus (model numbers A3082, A3289, A3290, A3291). The 16 Plus uses its own cell, separate from the 16, 16 Pro, 16 Pro Max, and 16e. Once the battery is seated and connected, the cell uses standard Li-ion chemistry matched to Apple’s reference design, so the iPhone 16 Plus powers on, charges, and holds charge the same way it did with the factory cell.

For context, Apple’s original iPhone 16 Plus cell rates at 4674 mAh, 3.875 V nominal, 4.5 V charging cutoff, and 18.11 Wh. As a result, this replacement battery matches every one of those numbers, which is what makes the runtime feel native after installation. In practice, customers commonly report that a tired iPhone 16 Plus jumps from a few hours of standby back to a full day on a single charge, which is the result of swapping a worn cell back to fresh, factory-spec capacity.

Who is this iPhone 16 Plus replacement battery for?

In particular, this battery suits three groups of buyers. First, iPhone 16 Plus owners whose original cell has degraded below acceptable runtime and who want to keep using the device for another couple of years. Second, NZ repair shops and trade technicians who need a reliable, local-stocked iPhone 16 Plus battery for paid repair work. Third, experienced DIY repairers who already own the precision tools and have replaced a screen or battery before. However, for first-time DIY repairers, GA Tech NZ offers professional fitting through the in-house repair service to remove the risk of damaging surrounding flex cables.

How long will the iPhone 16 Plus replacement battery last?

Typically, a new Li-ion cell retains 80 percent of its design capacity through roughly 500 full charge cycles, which works out to two or three years of normal daily use. After 500 cycles, capacity will begin to taper, and the next replacement window opens. Meanwhile, GA Tech NZ’s 6-month warranty covers manufacturing defects in the first 6 months from delivery, and the cell itself is built to deliver the full Li-ion design lifespan when charged within Apple’s voltage range.

NZ stock, dispatch, and in-house fitting

Since 2017, GA Tech NZ has supplied spare parts and repair services across New Zealand. Because GA Tech NZ holds the iPhone 16 Plus battery in local stock, weekday orders placed before 2pm ship the same day with tracked overnight courier delivery nationwide. Generally, urban delivery sits at $8 and rural at $13, with most orders landing the next business day. In addition, buyers who want a fitted result can book in-house iPhone 16 Plus battery replacement. Meanwhile, for complementary parts and tools, browse the iPhone parts and repair tools categories. Finally, to confirm Apple-published specifications for the iPhone 16 Plus, see the Apple iPhone 16 Plus technical specifications or the iPhone 16 Plus listing on GSMArena.

How to install the iPhone 16 Plus replacement battery

Generally, the iPhone 16 Plus battery sits beneath the display, secured by adhesive strips and connected via a flex cable to the logic board. Typically, a trained technician completes the full swap in 20 to 30 minutes. Therefore, GA Tech NZ offers in-house iPhone 16 Plus battery replacement for buyers unfamiliar with iPhone disassembly.

  1. Prepare the workspace and tools. First, use a clean, dust-free bench, a precision pentalobe and Phillips screwdriver kit, a suction cup, plastic opening picks, and a non-marring spudger.
  2. Power off the iPhone and open the chassis. Then remove the two pentalobe screws beside the USB-C port, apply gentle heat around the display perimeter, and lift the screen carefully with the suction cup. Of course, the display opens like a book from the right-hand side.
  3. Disconnect the battery and display. Next, remove the logic board shield, disconnect the battery flex first to isolate power, then disconnect the display and front sensor flex cables.
  4. Remove the old battery. First, apply electrical current to the battery’s debond tab using a 9V battery (90 seconds) or a 5 to 20V USB-C PD power source. After the adhesive releases, lift the battery from the chassis carefully. Meanwhile, avoid puncturing the cell.
  5. Seat the new replacement battery. After that, apply fresh battery adhesive strips to the chassis (sold separately), then place the new cell in position. Additionally, take care not to crimp or fold the flex cable.
  6. Reconnect and test before closing. Then reconnect the battery flex, display flex, and front sensor flex. Afterwards, power on the iPhone and verify it boots normally, accepts charge, and reads charge percentage in Settings.
  7. Close the chassis. Finally, reattach the logic board shield, reseal the display with fresh display adhesive (sold separately), and refit the two pentalobe screws to complete the install.

Compliance and testing

First, the supplier holds standard CE Declaration of Conformity (EU Council EMC Directive 2014/30/EU) and FCC Supplier’s Declaration of Conformity (FCC Part 15 Subpart B / ANSI C63.4:2014) for this battery line. In addition, the supplier holds standard lithium-battery transport and safety documentation, including UN38.3 test reports, MSDS, 1.2M drop test, and air transport identification under CNAS-accredited testing. As a result, the battery line ships with the compliance paperwork required for safe NZ courier transit.

Frequently asked questions

About capacity, fit, and runtime

What capacity is this iPhone 16 Plus replacement battery?

Specifically, the iPhone 16 Plus replacement battery is rated at 4674 mAh, 3.875 V nominal, 4.5 V charging cutoff, and 18.11 Wh. As a result, these numbers match the original Apple cell specification exactly, which is why runtime after installation tracks the factory experience closely.

Will the iPhone 16 Plus replacement battery restore my runtime?

Yes, indeed. Because the cell is zero-cycle and built to Apple’s original capacity specification, a tired iPhone 16 Plus typically returns to all-day standby and full-day mixed use after the swap. However, real-world runtime depends on screen brightness, mobile signal strength, and background app activity.

How long will the iPhone 16 Plus replacement battery last?

Generally, a new Li-ion cell retains 80 percent of its design capacity through approximately 500 full charge cycles. With normal daily use, that works out to roughly two to three years before the next noticeable degradation. Meanwhile, GA Tech NZ’s 6-month warranty covers any manufacturing defects in the first 6 months from delivery.

Will this battery fit my iPhone 16 Plus model number?

Specifically, this pack fits iPhone 16 Plus A3082, A3289, A3290, A3291. The 16 Plus uses its own cell, separate from the 16, 16 Pro, 16 Pro Max, and 16e. Therefore, confirm your A-number in Settings > General > About before ordering.

iOS behaviour, installation service, and warranty

What does iOS show in Battery Health after installation?

First, on iOS 18 and every iOS release after (including the current iOS version iPhone 16 Plus runs), Settings > Battery > Battery Health displays a real percentage for this replacement battery. In Settings > General > About > Parts and Service History, the battery is labelled “Unverified” because the cell does not carry Apple’s serialised identifier. In particular, this label is informational only. By contrast, on older iOS versions (iOS 13 through 17), Apple hid the percentage behind a Service notice; in addition, Apple changed this behaviour in iOS 18. Ultimately, the battery itself charges, discharges, and powers the iPhone 16 Plus the same way as the factory cell, regardless of the label.

Will this battery fit an iPhone 16 or iPhone 16 Pro Max?

No. The iPhone 16 Plus uses its own 4674 mAh cell. The standard iPhone 16 carries a 3561 mAh cell and the 16 Pro Max uses a similar-capacity 4685 mAh cell in a different physical size.

Can GA Tech NZ fit this battery for me?

Yes, indeed. In fact, GA Tech NZ offers in-house iPhone 16 Plus battery replacement. Generally, the full job takes 20 to 30 minutes in the workshop and includes a final test before handover.

How fast is delivery within New Zealand?

Generally, weekday orders placed before 2pm dispatch the same day with tracked overnight courier delivery nationwide. In addition, urban delivery is $8 and rural is $13. As a result, most orders arrive the next business day.

What warranty and return policy applies?

First, GA Tech NZ provides a 6-month warranty against manufacturing defects on this iPhone 16 Plus replacement battery. However, the warranty does not cover physical damage, installation errors, or water damage. In addition, GA Tech NZ accepts change-of-mind returns on unopened parts in new unused condition within 7 days of receipt under the GA Tech NZ terms and conditions.
