iPhone Battery Health Explained
Understanding Capacity Levels
100% - 90% (Excellent)
Near-new condition. Your phone will easily last a full day of heavy use without needing a charge.
89% - 80% (Good)
Industry standard for refurbished. The battery is still healthy and supports normal peak performance.
Below 80% (Degraded)
Considered "consumed" by Apple. You may experience unexpected shutdowns. Avoid buying phones in this range.
The 80% Rule for Refurbished iPhones
When shopping for a refurbished iPhone in Australia, the golden rule is to never accept a device with less than 80% battery health. Reputable sellers guarantee this minimum capacity, ensuring the phone can still deliver peak performance without unexpected shutdowns.
How to Maintain Your Battery Health
Avoid Extreme Heat
Leaving your phone in a hot car or direct sunlight degrades the lithium-ion battery faster than anything else.
Use Optimized Battery Charging
Keep this feature enabled in your settings. It learns your routine and waits to finish charging past 80% until you need it.
Don't Let It Die Completely
Try to keep your battery between 20% and 80% for optimal long-term health. Deep discharges stress the battery.
When Should You Replace the Battery?
If your refurbished iPhone’s battery eventually drops below 80%, you don’t need a new phone. A simple battery replacement (usually around $100-$150 AUD at an authorized repairer) will restore it to peak performance, extending the life of your device by years.
