The Always-On Display keeps key information visible even when your phone is locked.

To adjust it:

Settings → Display & Brightness → Always On

3. Unlock the Full 48MP Camera Power

One of the biggest reasons people upgrade to a used iPhone 14 Pro Max is the camera.

By default, photos aren’t always taken at 48MP. To enable full resolution:

Settings → Camera → Formats → Apple ProRAW

Turn on 48MP ProRAW for maximum detail.

Best situations for 48MP:

• Landscapes

• Architecture

• Travel photography

• Editing later in Lightroom

Keep in mind: 48MP photos take up much more storage space.

4. Use the Hidden 2x Zoom Trick

Your used iPhone 14 Pro Max offers 0.5x, 1x, 2x, and 3x zoom options.

The 2x zoom is especially clever — it crops into the 48MP sensor for sharp, high-quality images.

Perfect for:

• Portraits

• Food photos

• Street photography

Many users overlook this feature completely.

5. Improve Portrait Mode Instantly

Portrait photos look incredible on the used iPhone 14 Pro Max, but you can enhance them even further.

You can even change focus after the photo is taken.

For best results:

• Use natural light

• Avoid harsh overhead lighting

• Keep your subject 1–2 metres away

6. Action Mode for Smooth Video

If you record videos while walking, Action Mode is a must.

It stabilises footage dramatically — almost like using a gimbal.

Use it for:

• Travel videos

• Family moments

• Pet videos

• Social media content

Action Mode makes the used iPhone 14 Pro Max feel like a professional video camera.

---

7. Cinematic Mode for Professional-Looking Clips

Cinematic Mode allows background blur in video with automatic focus shifting.

Best used in:

• Outdoor settings

• Interviews

You can edit focus points after recording, giving your used iPhone 14 Pro Max serious creative flexibility.

8. Check Battery Health (Especially Important on Used Devices)

Go to:

Settings → Battery → Battery Health & Charging

Battery Saving Tips

To maximise battery performance:

• Disable Always-On Display if unused
