You just spent a small fortune on a titanium slab. It’s heavy, the screen is massive, and honestly, if you're only using it to scroll TikTok and send iMessages, you're wasting about 80% of what that A18 Pro chip can actually do. Most people think they know their way around iOS 18, but the real iPhone 16 Pro Max tricks aren't found in the "Tips" app that Apple forces onto your home screen. They’re buried under layers of menus or require a specific tactile rhythm that most users never stumble upon.
The iPhone 16 Pro Max is a weird beast. It’s the first time Apple really leaned into dedicated hardware for photography with the Camera Control button, and yet, that’s the one feature everyone seems to struggle with. It’s finicky. It’s sensitive. But once you calibrate it? It’s a game changer.
Mastering the Camera Control friction
The new button on the right side isn't actually a "button" in the traditional sense. It’s a high-precision force sensor coupled with a capacitive surface. If you’re just clicking it to take a photo, you’re missing the point. One of the best iPhone 16 Pro Max tricks involves the "light press" vs. the "double light press."
Try this: Open the camera, then lightly press the button once. You’ll see the zoom slider. But if you double-light-press, you get the full menu—Exposure, Depth, Zoom, Cameras, Styles, and Tone. The trick here is to go into your Settings > Accessibility > Camera Control and change the "Light Press Force" to "Firm." This prevents you from accidentally triggering the menu when you’re just trying to focus. Also, for the love of everything holy, turn off the "Clean Preview" mode if you actually want to see your UI while adjusting these settings.
Customizing the click
Did you know you can swap what that button does entirely? You aren't stuck with the stock Camera app. If you’re a pro user, you likely prefer Halide or Blackmagic Cam. In the settings, you can map the Camera Control to launch these third-party apps instantly. It makes the phone feel like a dedicated Leica or Sony rig rather than a smartphone with a lens attached.
The Action Button is underutilized
Remember when we just had a mute switch? That’s gone. The Action Button is now the nerve center of the device, yet most people just set it to "Flashlight" and call it a day. That’s a waste.
The real power lies in Shortcuts. You can create a folder of eight different shortcuts and map the Action Button to show that folder in a menu. Or, better yet, use a "Conditional Shortcut." This is where it gets nerdy. You can program the button to do different things based on the time of day or your location.
- If you’re at home in the morning, it opens your coffee maker app.
- If you’re at the gym, it starts your "Heavy Lifting" Spotify playlist.
- If it’s after 10 PM, it toggles your smart lights and turns on Do Not Disturb.
It takes ten minutes to set up but saves you hours of digging through folders every month. It’s about friction reduction.
Audio Mix is the sleeper hit of the year
Apple didn’t talk enough about the four "studio-quality" mics on this thing. If you’re recording video in a crowded bar or on a windy street, the audio usually sounds like garbage. Enter Audio Mix. This is one of those iPhone 16 Pro Max tricks that feels like literal magic.
After you shoot a video, hit "Edit" and tap the Audio Mix icon (it looks like three overlapping circles). You get four options: Standard, In-Frame, Studio, and Cinematic. "In-Frame" is the standout. It uses machine learning to identify the person speaking on camera and then digitally deletes every sound coming from outside the camera’s field of view. It’s essentially a virtual shotgun microphone. "Studio" mode makes it sound like the person is wearing a lavalier mic by removing room reverb. If you're a content creator, this basically kills the need for an external mic for quick social clips.
Dealing with the 6.9-inch display
Let’s be real: this phone is a surfboard. Even if you have huge hands, reaching the top corners is a recipe for a dropped screen.

Reachability is the old-school fix, but here’s the modern version: Back Tap. Go to Settings > Accessibility > Touch > Back Tap. Map "Double Tap" to "Reachability" and "Triple Tap" to "Control Center." Now, you just rap your finger on the frosted glass on the back of the phone to bring the top of the screen down. It’s much more reliable than trying to swipe the very bottom edge of the display, which often just triggers an app switch by mistake.
Visual Intelligence and the new Siri
With the A18 Pro, Siri is actually... useful? Sort of. Using the Camera Control button, you can long-press to trigger Visual Intelligence. It’s Apple’s answer to Google Lens. Point it at a restaurant to see hours and ratings. Point it at a flyer for an event, and it’ll automatically extract the date and add it to your Calendar. It’s built into the system level, so it doesn't feel like you're opening a separate search tool. It’s just "there."
ProRAW and Log Video: Stop filling your storage
The Pro Max has a 48MP Wide and a new 48MP Ultra Wide. By default, it shoots 24MP images to save space. If you want the full 48MP detail, you have to enable ProRAW Max. But here’s the thing: a single photo can be 75MB.
A better trick? Use JPEG XL. It’s a newer format Apple introduced that gives you the massive resolution and dynamic range of ProRAW but at a fraction of the file size. You have to toggle it in the Camera settings under "Formats."
And for video, if you aren't color grading your footage in DaVinci Resolve or Final Cut, do NOT shoot in ProRes Log. You will run out of space in ten minutes and the footage will look grey and washed out. Stick to "High Efficiency" unless you are literally making a movie.
Battery Longevity is a setting, not a myth
The 16 Pro Max has the best battery life of any iPhone ever, period. But lithium-ion batteries hate being at 100% all the time.
Apple added a new granular charging limit in iOS 18. Instead of just "Optimized Battery Charging," you can now set a hard limit at 80%, 85%, 90%, or 95%. If you plan on keeping this phone for three or four years, set it to 90%. It prevents the battery chemistry from degrading as fast. You lose a bit of daily runtime, sure, but the Pro Max has so much juice that 90% is still more than enough to get through a heavy day.
The "Hidden" Game Mode
Whenever you launch a heavy game like Resident Evil Village or Genshin Impact, the phone automatically triggers Game Mode. It doubles the Bluetooth polling rate for controllers and AirPods (reducing lag) and shuts down background tasks.
But you can actually see the impact by checking your "Background App Refresh" settings. If you’re noticing stutters in gaming, the trick is to turn off background refresh for everything except the essentials like Mail or Messaging. The A18 Pro is fast, but it’s still susceptible to thermal throttling if too many apps are fighting for the CPU.
Actionable Next Steps
To get the most out of your device right now, do these three things:
- Remap your Action Button to a "Folder" of your most-used apps or a custom Shortcut.
- Calibrate your Camera Control force to "Firm" in Accessibility to stop accidental menu pop-ups.
- Shoot a 10-second video of yourself talking in a noisy room, then apply the "Studio" Audio Mix in the edit menu just to see how wild the noise cancellation actually is.
The iPhone 16 Pro Max is only as "Pro" as you make it. If you treat it like a 15 Plus, you're missing out on the sophisticated hardware integration that justifies the price tag. Take the time to dig into the Accessibility and Camera menus—that's where the real power lives.
