iPhone 12 Pro Max Battery Replacement Melbourne
From $99 · 15–20 minutes · Same Day · Lifetime Warranty
6.7-inch Super Retina XDR OLED · A14 Bionic · 2020 · 3687 mAh
The iPhone 12 Pro Max came with Apple's largest battery at the time — a 3687 mAh cell — but its larger 6.7-inch display and 5G mmWave capability offset much of that advantage. By 2024–2025, many 12 Pro Max owners are reporting battery health below 80%, triggering iOS Performance Management on what should still be a high-performance device. iTech Repairs replaces iPhone 12 Pro Max batteries from $99 in Melbourne, with same-day service at Braybrook and Spotswood.

The iPhone 12 Pro Max has a larger battery than its siblings but its sensor-shift optical image stabilisation (OIS) system — unique to the Pro Max in the 12 lineup — also consumes additional power, particularly during video recording.
Signs Your iPhone 12 Pro Max Battery Needs Replacing
Faster Drain Than Expected for a Big Phone
Users bought the Pro Max for its larger battery. When it no longer outlasts a standard-sized phone, it's a clear sign of significant capacity loss.
Video Recording Drain
The 12 Pro Max's sensor-shift OIS and Dolby Vision HDR video recording are power-intensive. A degraded battery struggles to sustain these features for extended sessions.
Charge Percentage Jumping
Battery percentage dropping suddenly from 40% to 15% in minutes — indicating cells that can no longer discharge linearly.
Overnight Standby Loss
Losing 20%+ battery overnight in airplane mode or low-signal areas — a sign of a failing cell rather than software drain.
The 12 Pro Max's sensor-shift OIS, 5G modem, and 6.7-inch display remain useful tools. Restoring the 3687 mAh capacity at $99 means getting the big-phone battery life you paid for — without needing to buy a new device.
