Fix My Mobile helps Australians resolve iPhone battery and charging problems across models from iPhone 8 to iPhone 15. iPhones use lithium-ion batteries that degrade over time, and faulty charging accessories often stop the battery charging process. If the battery in your iPhone is draining quickly, not charging when plugged in, or showing low battery capacity, you can troubleshoot or book a replacement battery service for your iPhone repairs with our team today.
Why iPhone batteries degrade
iPhone batteries degrade because lithium-ion cells lose capacity with each charge cycle. Heat, poor charging habits, and heavy use all affect battery performance. Apple designs batteries to balance performance and safety, but every battery in your iPhone eventually loses efficiency.
A common sign is faster iPhone battery drain even after a full charge. For example, an iPhone 13 with 500 cycles may show a decrease in battery life down to 80% of original capacity. Background app refresh and charging your iPhone in hot environments further degrade the battery’s health.
Key reasons for battery degradation
- Normal charge cycles reduce battery capacity
- Heat and heavy use affect battery performance
- High-drain apps and features increase charging frequency
How to check your iPhone battery health
iOS provides built-in tools to check your iPhone battery and performance. Go to Settings > Battery > Battery Health & Charging to see maximum capacity, performance status, and service recommendations. Apple alerts users when they need to replace the battery.
For example, an iPhone 14 showing 75% battery capacity may drain completely before charging to full, affecting battery performance and daily use. Monitoring your battery’s health helps keep your iPhone reliable.
Steps to check battery health
- Open Settings
- Tap Battery
- Select Battery Health & Charging
- Review maximum capacity and service notes
Common charging problems in iPhones
Charging issues often come from faulty accessories or blocked ports. A faulty charging cable or adapter may prevent your iPhone from charging properly. Debris in the charging port can stop your iPhone charging capabilities completely.
For example, an iPhone isn’t charging when plugged in but works on wireless charging, which suggests port obstruction. A faulty charging cable or adapter can also cause the iPhone does not charge problem.
Common charging issues
- Faulty charging cable or adapter
- Debris in charging port
- Software bug affecting battery charging
- Misaligned wireless charging
Troubleshooting steps for charging issues
Simple troubleshooting steps can get your iPhone charging again. Use a certified charger and cable, and test with a different adapter if the iPhone is not charging. Clean the port carefully and restart your device. Updating iOS may also solve battery not charging bugs.
If your iPhone isn’t charging when plugged in despite trying different accessories, you may need a battery service or charging port repair. For example, an iPhone 15 model that refuses to charge after port cleaning likely needs professional repair.
Why is my iPhone not charging?
Your iPhone may not charge because of a faulty cable, adapter, or debris. Test different charging accessories to get your iPhone charging properly.
Should I let my battery drain completely before charging?
No. Allowing the battery in your iPhone to drain completely before charging shortens lifespan. Charge your iPhone between 20% and 80% to improve battery longevity.
How do I know if my cable is faulty?
If your iPhone does not charge with one cable but works with another, the first cable is faulty. Always use certified charging cables and adapters.
How much does battery replacement cost?
Prices vary. Apple offers standard rates, while independent repairers like Fix My Mobile provide competitive battery replacement options.
When to replace your iPhone battery
You need to replace the battery when its health falls below 80%, or if the iPhone battery and performance cause shutdowns or poor usage times. Frequent charging and rapid drain are also signs.
For example, an iPhone 8 that needs charging three times daily shows clear battery problems. A replacement battery restores charging capabilities and performance.
Indicators you need to replace the battery
- Battery capacity below 80%
- Rapid iPhone battery drain
- Unexpected shutdowns
- iPhone not charging when plugged

How to extend your iPhone’s battery life
You can improve battery life by adjusting habits and settings. Enable Low Power Mode, reduce background app refresh, and avoid heat. Use certified charging accessories to keep your iPhone charging properly.
For example, charging an iPhone 15 overnight with a certified cable helps maintain the battery’s health and charging capabilities. Proper care extends both short-term iPhone battery life and long-term performance.
Tips to extend battery life
- Enable Low Power Mode
- Avoid extreme heat or cold
- Use authorised charging cables and adapters
- Update iOS regularly
When this may not be the right fit
If your iPhone is covered by AppleCare or warranty, Apple support may be the best option. Their repairs are backed by Apple guarantees. However, turnaround time may be longer than Fix My Mobile.
How to judge if you need this now or later
Battery replacement is urgent if your iPhone battery not charging or shutting down unexpectedly. If your device still lasts a full day, you may wait until battery capacity drops further. The choice depends on daily usage needs.
