An iPhone battery replacement in Auckland costs between roughly $69 and $300 NZD at iRepair, depending on your model and whether you choose a genuine Apple or high-quality aftermarket battery. It is one of the most common — and most cost-effective — repairs we do, and it takes about 45 minutes. This guide covers pricing for every current iPhone, the signs your battery is failing, and how to choose between genuine and aftermarket.

Signs Your iPhone Needs a New Battery
Lithium-ion batteries wear out with every charge cycle — most iPhones noticeably degrade after about 500 full cycles, or roughly two years of daily use. Watch for these signs:
- Battery Health below 80% — go to Settings > Battery > Battery Health & Charging. Below 80% Maximum Capacity, Apple no longer considers the battery to be at peak performance, and you may see a "Service" recommendation.
- Unexpected shutdowns — the phone powers off at 30%, 20%, or in the cold, even though it shows charge remaining. This is the classic sign of a worn cell that can no longer deliver peak current.
- Rapid drain — the battery drops from 100% to flat far faster than it used to, or doesn't last a full day with light use.
- Performance throttling — iOS deliberately slows a phone with a degraded battery to prevent shutdowns. A battery swap restores full speed.
- Heat or swelling — a hot phone during normal use, or a screen or back that is lifting, means the battery may be swelling. Stop using the phone and bring it in — a swollen battery is a safety risk, the same danger we cover in our swollen laptop battery guide.
Genuine Apple vs Aftermarket Batteries
Like screens, the battery decision comes down to genuine Apple versus high-quality aftermarket. Both have a place:
- Genuine Apple batteries — identical capacity and chemistry to the original, and the Battery Health percentage displays normally with no "Unknown Part" or "Service" warning in Settings. Best for phones under two years old and anyone who wants the exact factory experience. Costs more.
- High-quality aftermarket batteries — reputable cells that match or exceed original capacity and perform excellently day to day. On iOS they may show a battery-health notice (Apple pairs genuine batteries to the device), but charging, runtime, and safety are not affected. A cost-effective choice for older phones or tighter budgets.
At iRepair we explain both options before you commit and never fit a cheap, uncertified cell. The same genuine-versus-aftermarket trade-offs apply to screens and other parts — our genuine Apple battery vs aftermarket guide goes deeper on the technical differences, and our iPhone screen replacement cost guide covers the same decision for displays.
Why Battery Health Matters — and What "80%" Really Means
Apple rates an iPhone battery to hold up to 80% of its original capacity at 500 complete charge cycles under ideal conditions. Once you drop below 80%, you are running on materially less capacity than the phone was designed around, which is why drain and shutdowns accelerate. Newer models (iPhone 15 and 16) are rated to 80% at 1,000 cycles, so they last longer before needing a replacement — but the same rules apply once they get there.
Replacing the battery resets Maximum Capacity to 100% and removes any performance throttling iOS had applied. For most people, a battery replacement is the single cheapest way to make an ageing iPhone feel new again.
How Long Does an iPhone Battery Replacement Take?
At iRepair Avondale, most iPhone battery replacements are completed in 30–45 minutes while you wait. The process:
- Check-in and diagnosis — we confirm battery health and check for swelling or water ingress (5 minutes)
- Screen removal — the display is carefully lifted to access the battery (10 minutes)
- Battery swap — the old cell is removed, new adhesive is fitted, and the replacement battery installed (10–15 minutes)
- Testing & calibration — we verify charging, health readout, and reseal the water-resistance gasket before handback (5–10 minutes)

We are at 391 Rosebank Road, Avondale, serving customers from across Auckland including New Lynn, Mt Albert, Henderson, Waterview, Blockhouse Bay, and Green Bay.

Is It Worth Replacing the Battery or Upgrading?
A battery replacement costing a fraction of a new handset — on a phone worth $800–$1,900 — is almost always the smarter financial move. You keep your data, your settings, and a phone you already know, and you restore full battery life and performance for far less than buying new.
The only time we advise against it is when the phone has multiple failing components at once — a degraded battery plus a cracked screen plus charging problems — and the combined repair approaches the price of a replacement handset. For a full breakdown of that decision, read our repair vs trade-in comparison. If your phone is charging slowly or not at all, it may be the port rather than the battery — see our iPhone charging problems guide first. And if you are weighing a laptop battery too, our Auckland laptop repair guide covers battery and other common faults.
