Camera Tips
- 5x Telephoto: Tap the 5x preset for optical zoom. The 3D sensor-shift OIS keeps shots steady. Use for portraits, wildlife, and distant subjects. Digital zoom up to 25x.
- 48 MP Main Camera: In Settings > Camera > Formats, enable Resolution Control to capture full 48 MP ProRAW or HEIF images. For everyday, the default 24 MP mode balances detail and file size.
- Night Mode: Automatic in low light. Keep the phone steady for 2-3 seconds. For astrophotography, use a tripod and the 30-second Night mode exposure.
- Portrait Mode: Select Portrait from the mode bar. Adjust depth control after taking the shot. The 5x telephoto creates a flattering compression for portraits.
- Action Mode: For smooth video while moving, tap the Action mode icon (running figure). It uses the ultra-wide camera and crops slightly.
- ProRAW & ProRes: ProRAW for maximum editing flexibility. ProRes video (up to 4K 60fps) for professional workflows. Requires high-capacity storage.
- Spatial Video: Record spatial video for Apple Vision Pro (requires enabling in Settings > Camera > Formats). Works with the main and ultra-wide cameras.
Action Button Customisation
- Go to Settings > Action Button.
- Swipe through the available actions: Silent mode, Focus, Camera, Flashlight, Voice Memo, Magnifier, Translate, Accessibility, Shortcuts, or No Action.
- You can assign a Shortcut that opens a menu of options (e.g., choose between Flashlight, Camera, and Voice Memo). Create the Shortcut first, then assign it.
- Press and hold the Action button to trigger the action. A quick haptic feedback confirms activation.
USB-C Connectivity
- Charging: Use any USB-C cable and adapter. For fast charging, use a 20W or higher USB-C PD charger (0 to 50% in 30 minutes).
- Data Transfer: Connect to a Mac or PC with USB-C. The phone supports USB 3 speeds (10Gbps). Use a USB-C to USB-C cable for best performance.
- External Displays: Connect to a USB-C monitor or TV (up to 4K HDR). The phone mirrors or extends the display.
- Accessories: Connect USB-C flash drives, SSDs, keyboards, mice, and Ethernet adapters. The phone can charge small devices like AirPods via USB-C (up to 4.5W).
Battery & Charging
- Battery life: Up to 29 hours of video playback. Heavy use (gaming, 5G) will reduce runtime.
- Fast charging: 20W USB-C PD charger gives about 50% in 30 minutes.
- MagSafe wireless charging: Up to 15W with a MagSafe charger. Standard Qi chargers provide 7.5W.
- Battery health: Go to Settings > Battery > Battery Health & Charging to check maximum capacity and enable Optimised Battery Charging. For long-term health, consider the 80% Limit option if you charge overnight.
- Reverse wired charging: The iPhone 15 Pro Max can charge AirPods or Apple Watch via USB-C at 4.5W. Enable in Settings > Battery > Reverse Charging (or it works automatically when connected).
Troubleshooting & Common Problems
| Problem | Likely Cause | What to Try |
|---|---|---|
| Action button not working | Not configured, or the assigned shortcut failed | Go to Settings > Action Button and reassign. Test a different action. If using a Shortcut, ensure the Shortcut works manually. |
| Camera app crashes | Software glitch, or low storage | Restart the phone. Clear camera cache (iOS doesn’t have direct cache clear; restart or offload the app). Check Settings > General > iPhone Storage and free space. |
| 5G battery drain | Weak 5G signal, or background apps | Switch to 4G/LTE in Settings > Cellular > Cellular Data Options > Voice & Data. Turn off Background App Refresh for unused apps. |
| Wi-Fi or Bluetooth not connecting | Router or interference | Restart router and phone. Forget network and reconnect. For Bluetooth, toggle off/on and re-pair. Reset network settings if persistent. |
| Overheating during gaming or camera | Intensive load | Remove case, avoid direct sunlight, close background apps. The phone will throttle performance to cool down. |
| Face ID not working | Dirty TrueDepth camera, or mask | Wipe the front camera area. Re-scan your face. If wearing a mask, enter passcode or use Apple Watch unlock. |
| USB-C port not charging | Debris or wrong cable | Clean the port with a wooden toothpick. Use a USB-C PD charger and quality cable. |
