In the ever-evolving world of smartphones, competition continues to intensify between brands offering flagship devices. This year, two powerful contenders have entered the spotlight: the OnePlus 13T, also known in some regions as the OnePlus 13s, and the much-anticipated iPhone 16 Pro Max. Both devices come packed with top-tier hardware, sleek designs, and advanced software experiences. But when it comes down to pure performance, which one stands out?
In this detailed analysis, we’ll explore every aspect of their speed, usability, and overall experience — from boot-up times to gaming performance and everything in between. Whether you’re a power user, gamer, or everyday smartphone owner, this comparison will help you understand which device might better suit your needs.
Design and In-Box Accessories: A Tale of Two Approaches
Let’s start by looking at what you get straight out of the box.
When unboxing the OnePlus 13T, users are greeted with not just the phone but also a silicone protective case and a powerful 80W charging brick. In today’s world, where many brands have started removing chargers and accessories from their packaging, OnePlus deserves credit for still including these essentials. This small gesture not only saves buyers extra expenses but also ensures a seamless setup from day one.
On the other hand, the iPhone 16 Pro Max follows Apple’s minimalist packaging approach. Inside the sleek box, you’ll primarily find the phone and a USB-C charging cable — no charger or case included. While this may align with Apple’s environmental goals, some users might find it inconvenient, as they’ll need to purchase these accessories separately.
Processing Power: Snapdragon 8 Elite vs A18 Pro
Under the hood, both smartphones boast incredible processing power, but they take different paths to get there.
The OnePlus 13T runs on Qualcomm’s Snapdragon 8 Elite chip, built on the advanced 3nm process by TSMC. This chipset features a custom Orion CPU architecture, designed to deliver exceptional performance and energy efficiency. Paired with ColorOS 15, the phone promises a buttery-smooth user experience.
Meanwhile, the iPhone 16 Pro Max houses Apple’s latest A18 Pro chip, also built on a 3nm process. With its tightly integrated iOS ecosystem, the A18 Pro aims to balance raw speed with long-term software support and stability.
Both processors are engineered for flagship-level performance, but how do they stack up in real-world use?
Boot-Up Test: Speed Right from the Start
Kicking things off with a boot-up speed test, the OnePlus 13T surprises by booting up faster than the iPhone 16 Pro Max. While the difference may only be a few seconds, it showcases OnePlus’s commitment to optimizing startup performance.
This quick start can be attributed to faster memory initialization and lighter pre-installed services on the OnePlus device, while iOS tends to load more background processes at startup.
Although most users won’t reboot their phones daily, a quicker boot time can still reflect a phone’s general responsiveness.
App Launch Speed: Everyday Usage Faceoff
Next, let’s dive into launching everyday apps like the dialer, App Store, camera, and settings.
In the dialer test, the OnePlus 13T opened the app just a split-second faster than the iPhone. When launching the App Store (Google Play Store vs Apple App Store), the OnePlus again took the lead, loading content swiftly and rendering interface elements faster.
The camera app, especially for selfies, opened quicker on the OnePlus as well — a notable advantage for those who love spontaneous photo moments.
Even when jumping into settings, the OnePlus maintained its speed edge. While these differences are minor, they accumulate in day-to-day use, making the phone feel snappier overall.
Display Cutout Design: Hole-Punch vs Pill
Moving beyond speed, it’s worth noting the design differences on the front of these devices. The OnePlus 13T sports a small center hole-punch cutout for its selfie camera. This design feels unobtrusive and modern, offering more usable screen space.
In contrast, the iPhone 16 Pro Max retains its pill-shaped cutout, housing both the selfie camera and Face ID sensors. While Apple’s Dynamic Island software feature adds functionality around this cutout, some users may still prefer the cleaner look of a single hole-punch.
Gaming Performance: Pushing Graphics to the Max
Gaming is where both smartphones shine.
Starting with Genshin Impact, one of the most graphically demanding mobile games, both devices performed admirably at maximum graphics settings. Interestingly, the iPhone 16 Pro Max loaded the game slightly faster, offering quicker in-game asset rendering and smoother initial animations.
However, when switching to another popular game, Wuthering Waves, the OnePlus 13T pulled ahead, opening the game faster and maintaining more consistent frame rates during intense battles. The superior cooling system and GPU optimization in the OnePlus seem to give it a slight edge here.
Moving to PUBG Mobile, the iPhone once again loaded faster, while in Call of Duty Warzone Mobile, the OnePlus regained its lead.
No matter which platform you choose, both devices can handle high refresh rates, ultra graphics settings, and long gaming sessions without overheating or throttling — making them ideal for mobile gamers.
Everyday Apps: Instagram, Spotify, and More
For daily social and streaming apps like Instagram, Spotify, and Starbucks, the OnePlus 13T consistently launched these apps a tad quicker. While these milliseconds may not drastically change your user experience, they reinforce the snappy performance of OnePlus’s software-hardware integration.
Apple’s iOS, meanwhile, continues to prioritize smooth animations and transitions, which can feel slower in comparison but are intentionally designed for a seamless visual experience.
Rendering and Exporting: Creative Workflows Tested
When it comes to heavier tasks like video rendering and exporting in apps like Adobe Premiere Rush, the iPhone 16 Pro Max takes the crown. Thanks to its superior neural engine and hardware acceleration for creative apps, the iPhone exported large files noticeably faster.
This makes the iPhone a stronger choice for content creators who rely on mobile video editing or work with large photo and video files on the go.
RAM Management: Keeping Apps Alive
In RAM management tests, the OnePlus 13T showcased impressive multitasking capability, keeping more apps running in the background without needing to reload. It successfully held demanding games like Genshin Impact and Wuthering Waves open while switching between multiple other apps.
The iPhone, while still strong in multitasking, refreshed some heavier apps like Wuthering Waves, likely due to iOS’s stricter memory management policies aimed at preserving battery life.
If you frequently juggle between apps, the OnePlus 13T may give you a smoother experience without as many reloads.
Biometrics: Fingerprint Scanner vs Face ID
Security and convenience also differ between these two devices. The OnePlus 13T uses an in-display fingerprint scanner, which was both quick and reliable during testing.
The iPhone 16 Pro Max, sticking with Face ID, remains one of the most secure and fast facial recognition systems available. Both authentication methods unlocked their respective devices in under a second in most conditions.
Whether you prefer unlocking your phone with a finger or a glance comes down to personal preference — both systems work well.
Shortcut Keys: Action vs Custom
Finally, comparing their physical shortcut buttons: the iPhone’s Action Key felt slightly faster in executing assigned tasks compared to the OnePlus 13T’s customizable shortcut button. While the difference was minimal, Apple’s tight hardware-software integration gives its Action Key a slight speed advantage.
Final Verdict: Which Flagship is Right for You?
After comparing these two powerhouse devices across boot times, app launches, gaming, multitasking, biometrics, and more, it’s clear that both the OnePlus 13T and iPhone 16 Pro Max excel in different areas.
✅ If you value faster boot-ups, quicker app launches, better RAM management, and included accessories, the OnePlus 13T shines as a speed-focused flagship that still offers excellent value.
✅ If you prioritize video rendering performance, software longevity, tighter ecosystem integration, and superior Face ID, the iPhone 16 Pro Max might be the better fit.
Ultimately, your choice depends on your priorities: whether you want sheer speed in daily interactions or long-term software stability and creative app performance.
No matter which device you pick, both represent the pinnacle of smartphone innovation in 2025 — proving that competition continues to push mobile technology forward.
