For your first repair, we recommend referring to the IFIX mobile phone repair video, which will give you a better understanding of your phone.
1. Preparations Before Repair
1.1 Check Warranty Status
- Verify if the iPhone is still under Apple’s warranty or AppleCare+ coverage.
- Unofficial repairs may void the warranty (except in regions with "Right to Repair" laws).
2.1 Accurate Diagnosis
- Use Apple’s official diagnostics tool (*Settings > Privacy & Security > Analytics & Improvements > Start Diagnostics*).
- Document symptoms: when they occur, triggering conditions, error codes, etc.
3.1 Prepare the Right Tools
- Basic toolkit: P2 pentalobe screwdriver, Y000 Phillips screwdriver, suction cup, spudger.
- Professional tools: Anti-static wrist strap, heat gun/heating pad (for screen removal).
- Recommended: iFixit toolkit (reliable quality).
2. Key Notes During Repair
1.1 Safety First
- Disconnect the battery first (lithium batteries can catch fire if punctured).
- Use plastic tools instead of metal to avoid short circuits.
- Work in an anti-static environment (use an anti-static mat if possible).
2.1 Parts Compatibility
- Ensure replacement parts match your exact iPhone model (even within the same generation, there may be differences).
- Note regional variations (e.g., Chinese models may have different components).
3.1 Disassembly Tips
- Arrange screws in order (different screws may have varying lengths).
- Take photos of each step to document the connector and screw positions.
- Apply appropriate force (many fragile flex cables inside).
4.1 Special Notes for Screen Repairs
- True Tone display requires transferring the original screen chip or using a programmer.
- Face ID repairs are extremely complex—not recommended for beginners. 
4. Post-Repair Steps
1.1 Functional Testing Checklist
- Test all buttons.
- Full touchscreen responsiveness check.
- Microphone/speaker test.
- Wireless functions (Wi-Fi, Bluetooth, cellular).
- Biometrics (Touch ID/Face ID).
2.1 Software Calibration
- New batteries need a full charge-discharge cycle for calibration.
- Screens may require True Tone recalibration (needs professional tools).
3.1 Disposing of Old Parts
- Lithium batteries require special recycling (do not throw in regular trash).
- Consider the resale value of original parts (e.g., OEM screens).
5. When to Seek Professional Help
Stop DIY repairs if you encounter:
- Visible damage to the logic board (bending, burn marks).
- Liquid damage before full drying.
- Persistent issues after multiple attempts.
- Unusual heat or smoke during repair.
