28 Tips and Tricks for iPhone 15, 15 Plus, 15 Pro, 15 Pro Max: Unlock Your iPhone’s Full Potential
The iPhone 15 series is packed with features, but not all of them are obvious at first glance. Whether you’re a first-time iPhone user or upgrading from an older model, this guide will walk you through 28 essential tips and tricks to help you customize your device, extend battery life, take stunning photos, and protect your privacy—all. Let’s dive in!
Battery & Charging Tips
(Save power, extend battery life, and keep your iPhone running smoothly.)
1: Check Your Battery Health
Your iPhone’s battery health tells you how much charge it can hold compared to when it was new. To check:
- Open Settings > Battery > Battery Health & Charging.
- Look at Maximum Capacity:
- 100%: Your battery is brand new.
- Below 80%: Consider replacing the battery for better performance.
Why it matters: A healthy battery lasts longer between charges. If you notice your phone dying quickly, this is the first place to check.
2: Enable Optimized Battery Charging
This feature slows down charging overnight to reduce wear on your battery.
- Go to Settings > Battery > Charging Optimization.
- Select Optimized Battery Charging.
Pro Tip: For even better battery health, enable 80% Limit (iPhone 15 Pro only). This stops charging at 80% to minimize long-term damage.
3: Use USB-C for More Than Charging
The iPhone 15’s USB-C port isn’t just for charging. Try these:
- Transfer Files: Plug in a USB-C flash drive to save photos or videos.
- Connect Accessories: Use a USB-C microphone for clearer video calls.
- Charge Other Devices: Power up your AirPods or Apple Watch.
| iPhone Model | USB Speed | Best Uses |
|---|---|---|
| iPhone 15/15 Plus | USB 2.0 | Charging, basic accessories |
| iPhone 15 Pro/Pro Max | USB 3.0 | Fast file transfers, pro cameras |
Note: USB 3.0 is 20x faster than USB 2.0. You’ll need a USB 3.0 cable (not included in the box).
Camera & Photography Tips
(Take pro-level photos and videos with these hidden features.)
4: Shoot in 48MP Mode

- Go to Settings > Camera > Formats.
- Turn on ProRAW & Resolution Control.
- Open the Camera app and tap the HEIF Max icon (looks like mountains).
Why it matters: 48MP photos are perfect for printing or cropping without losing quality.
5: Auto Portrait Mode
Your iPhone automatically saves depth data for photos of people, pets, or objects. To use:
- Take a regular photo (no need to switch to Portrait Mode).
- Open the photo and tap Edit.
- Tap the Portrait icon to add background blur.
Pro Tip: Adjust the blur strength by sliding the f-stop bar (e.g., f/2.8 for heavy blur, f/16 for minimal blur).
6: Use the 5x Zoom on iPhone 15 Pro Max
The Pro Max model has a dedicated 5x zoom lens for crisp close-ups:
- Open the Camera app.
- Tap the 5x button for optical zoom (no quality loss).
- Pinch to zoom up to 25x digitally (works best in bright light).
